AB  - The hydrolytic stability of two nano-SiO2-based UF composites with derivates of coumarin (names as K-1 and K-2) was investigated. K-1 is 3-nitro-4-(p-tolylamino)-2H-chromen-2-one and K-2: 4-((3-nitro-2-oxo-2H-chromen-4-yl)amino)benzenesulfonamide. Two types of nano-silica-based urea–formaldehyde (UF), composite materials with a formaldehyde-to-urea (F/U) ratio of 0.8, were synthesized (UF/K-1/SiO2, and UF/K-2/SiO2). The hydrolytic stability of modified UF composite was determined by measuring the mass loss and liberated formaldehyde concentration of modified UF composite after acid hydrolysis. Obtained results showed that the hydrolytic stability of modified resins with derivates of coumarin was enhanced. The formaldehyde emission of modified UF/K-1/SiO2 composite is lower compared with UF/K-2/SiO2 composite. The thermal behavior of materials was studied by non-isothermal thermo-gravimetric analysis and differential thermal gravimetry supported by data from ATR-IR spectroscopy. The shift of temperature values for selected mass losses (T5%) to a high temperature indicates the increase in thermal stability of samples based on UF resin modified with K-2. © 2020, Springer-Verlag GmbH Germany, part of Springer Nature.

AB  - Urea-formaldehyde resin (F/U ratio of 0.8)/thermally activated montmorillonite (UF/Delta TK10) nanocomposite was synthesized. The hydrolytical, thermal, and UV radiation stability of UF/Delta TK10 nanocomposites are determined. UF hybrid nanocomposites have been irradiated with UV light with a wavelength of 254 nm and 366 nm, and after that, their radiation stability was evaluated. The free formaldehyde (FA) percentage in all prepared samples was determined. The sample was characterized by using X-ray diffraction analysis (XRD), nonisothermal thermogravimetric analysis (TGA), differential thermal analysis (DTA), and differential thermal gravimetry (DTG), with infrared (FTIR) spectroscopy. Crosslinked UF/Delta TK10 nanocomposite shows the highest resistance to acid hydrolysis after UV irradiation at a wavelength of 254 nm. The values for T-5% are identical for the unirradiated and UV irradiated (wavelength of 366 nm) UF/Delta TK10 nanocomposite. It can be concluded that this sample is thermally most stable and shows good resistance to UV irradiation.

AB  - The thermal stability of organic-inorganic nano-composites prepared by a two-stage polymerization of urea-formaldehyde resin (UF) with furfuryl alcohol (FA) and TiO2 before and after irradiation has been researched. The two resins of urea-formaldehyde–TiO2 composites, named: UF/TiO2 and UF/TiO2/FA, were synthesized. The thermal stability of obtained materials was studied by non-isothermal thermo-gravimetric analysis (TG), differential thermal gravimetry (DTG) and differential thermal analysis (DTA). UF hybrid composites have been irradiated (50 kGy) and after that their radiation stability was evaluated on the basis of thermal behavior. The free formaldehyde (HCOH) percentage in all prepared samples was determined. The minimum percentage values of free formaldehyde (0.04% and 0.03%) for UF/TiO2 and UF/TiO2/FA, respectively, after irradiation dose of 50 kGy are detected. The shift of temperature values for selected mass losses (T10%) to a high temperature indicates the increase in thermal stability of samples based on UF resin modified with FA.

AB  - The powder recycled rubber (PRR) can be used as a filler and a modifier for elastomeric materials and asphalt. Composites based on elastomers and recycled rubber powders are a serious challenge for the environment. The main goal of this paper was to study the effect of rubber powder on the mechanical properties of elastomeric composites based on three precursors of the network. Triple blends were prepared using non-polar natural rubber (NR), polyisoprene rubber (BR), and styrene-butadiene rubber (SBR) (mass ratio 40/40/20). In all rubber compounds, the carbon black (CB)/PRR mass ratio is constant (60). Samples were prepared using two roll mill. The characteristics of hardening (optimum cure time, scorch time, minimum and maximum torque) of rubber mixtures were tested. Tensile strength, modulus at 100% elongation and elongation at break are decreasing with PRR ratio is increasing. It is due to poor adhesion of PRR into NR/BR/SBR/CB matrix. The thermal degradation temperature shifts to a higher temperature up to 5 phr of PRR in NR/BR/SBR/CB rubber blends. Fourier-transform infrared spectra of NR/BR/SBR/CB/PRR samples show that the absorption bands shifted 7–15 cm−1 to higher wavenumbers and confirmed rubber–filler interaction. Morphology was assessed by scanning electron microscopy. POLYM. COMPOS., 40:1307–1314, 2019. © 2018 Society of Plastics Engineers. © 2018 Society of Plastics Engineers

AB  - In this applicative work, two types of silica filler were used to increase the adhesion strength between steel and elastomeric hybrid materials based on chlorosulfonated polyethylene rubber (CSM) and polychloroprene rubber (CR) as network precursors. Precipitated silica (PS) with the average size of primary particles 15 nm and diatomaceous earth (DE) with the average size of primary particles 28 μm were used to ascertain differences in metal-elastomer compounds adhesion strength caused by different particle size. The ratio of network precursors in CSM/CR rubber blends was 50:50 (w/w). The filler loading was in the range of 0–35 phr. Characteristics of the obtained composites were examined by combining the cure kinetics, adhesion strength and the dynamic mechanical properties. The viscoelasticity of obtained hybrid materials was assessed by the mechanical spectrometer (in a single cantilever bending mode) in the temperature range from −50 °C to 150 °C using multifrequency mode.

AB  - The elastomeric materials based on NR/BR/SBR ternary rubber blend were investigated. The polyisoprene (NR), butadiene (BR) and styrene butadiene (SBR) rubbers were used as network precursors and carbon black (CB) as an active filler (60 phr) for elastomeric materials preparation. For sample preparation, the mass ratio of NR to BR was constant, 1:1, but the SBR content was varied from 0 to 80 phr. The morphological, mechanical and thermal properties of prepared elastomeric materials were determined using scanning electron microscopy (SEM), mechanical tensile measurements and thermogravimetric analysis (TGA). Mechanical properties were assessed before and after thermooxidative aging during 168 h at 100 °C. The values of tensile strength, elongation at break, and hardness decrease up to 40 phr of SBR content and after that are increasing, but abrasion resistance of ternary rubber blends increases. The thermal decomposition temperature obviously shifted to a higher temperature for the sample with 40 phr of SBR. © 2019, CI and CEQ. All rights reserved.

AB  - The goal of this work was to synthesize and characterize ternary rubber blends based on polyisoprene (natural rubber (NR)), polybutadiene rubber (BR), and styrene-butadiene rubber (SBR) (NR/BR/SBR = 25/25/50) reinforced with different loading silica (SiO2) nanoparticles (0-100 part per hundred parts of rubber (phr)). The specimens were subjected to thermooxidative aging at 100 degrees C, for two times: at 72 and 168 h, respectively, and then mechanically stretched to fracture by tension with a Zwick 1425 (Zwick GmbH, Ulm, Germany) universal tensile testing machine. Rheological and mechanical properties were used as characterization of the ternary rubber blends. The reinforcing performance of the filler was investigated using rheometric, mechanical, and swelling measurements, thermogravimetric analysis, scanning electron microscopy, and Fourier transform infrared spectroscopy with attenuated total reflectance. Hardness, tensile strength, elongation at break, and swelling degree were assessed before and after thermal aging. There was a remarkable decrease in the optimum cure time (t(c90)) and the scorch time (t(s2)), which was associated with a decrease in the cure rate index of (NR/BR/SBR = 25/25/50) ternary rubber blend with 60 phr of filler loading. Interaction between rubber blend and SiO2 nano-filler is confirmed by moving absorption band from 1450 cm(-1) to 1480 cm(-1).

AB  - Elastomers are very often used in severe environments, for instance, in nuclear power plants, where they may be degraded by high-energy radiation and heat. The ageing behaviour of materials used in different equipments is very important. Elastomers based on chlorosulfonated polyethylene (CSM) are used for cable jacketing materials and have excellent radiation resistance needed in nuclear power stations. In the current work, the influence of gamma-irradiation dose (100, 200 and 400 kGy) on the ageing of reinforced blends based on CSM, styrene butadiene rubber (SBR) and natural rubber (NR) has been evaluated. The content of silica in CSM/SBR and CSM/NR rubber blends was varied. The curing behavior of compounds was estimated using the oscillating disk reometer. The irradiation of nano composites has been performed in air in the Co 60 radiation sterilization unit with the dose rate of 10 kGy h(-1). The thermal properties were studied by thermogravimetric test. The mechanical properties (hardness, modulus at 100% elongation, tensile strength and elongation at break) were determined before and after irradiation. A decrease in the elastic modulus and in the strain at break has been observed with increasing irradiation. At higher doses, the network chain scissions become the main degradation process, the cross-linked topology becomes irregular, and material contains more and more weak zones, which deteriorate the ultimate properties.

AB  - In this study, the thermal behavior of modified urea-formaldehyde (UF) resin with nanosilica (nano-SiO2), wood flour (WF), and their mixture of SiO2/WF was investigated. Five modified UF hybrid composite materials with 0.8 F/U ratio with different filler were synthesized using the same procedure. The thermal behavior of materials was studied using nonisothermal thermogravimetric analysis, differential thermal gravimetry (DTG), and differential thermal analysis and supported by data from infrared spectroscopy. The shift of DTG peaks to a high temperature indicates the increase in thermal stability of modified UF resin with hybrid SiO2/WF fillers, which is confirmed by the data obtained from the Fourier transform infrared spectroscopic study. It was estimated that the UF/WF samples based on nano-SiO2 have better thermal stability.

AB  - Chlorosulfonated polyethylene rubber (CSM) was blended with chlorinated natural rubber (CNR) with various formulations and blend ratios (CSM/CNR: 100/0; 75/25; 50/50; 25/75; 0/100) keeping the total waste rubber powder (WRP) content constant at 50 phr (parts per 100 rubber). Rheological, mechanical, dynamic mechanical and thermal aging properties as well as irradiation resistance were used as characterization of the blends. The amount of CNR in blends significantly affected the properties of the blends. The CSM/CNR/WRP rubber blend (50/50/50) possessed higher tensile strength compared with pure CSM and CNR rubber even after irradiation or thermal aging. Modulus, tensile strength and hardness of the blends appeared to increase, but elongation at break decreased progressively with increasing CNR content. These properties decreased in rubber blends after thermal aging. After irradiation, hardness, modulus and tensile strength increased up to 200 kGy and then decreased significantly for the blends with high CNR content, whereas no change in modulus was observed. CNR and CSM showed damping peaks at about 65 and -45 degrees C, respectively, and these values correlate with the glass transition temperatures (T(g)s) of CNR and CSM, respectively. The shift in the T-g values was observed after blending, suggesting an interfacial interaction between the two phases probably caused by the covulcanization in CSM/CNR blends.

AB  - This work aimed to study the effects of gamma radiation on the properties of ethylene propylene diene terpolymer/chlorosulfonated polyethylene rubber blend reinforced with 50 phr of carbon black and cross-linked either with sulfur/tetramethylthiuram disulfide or dicumyl peroxide. Irradiation doses were 100, 200, and 400 kGy. It was observed that doses higher than 200 kGy practically destroy the assessed properties of all obtained elastomeric materials, irrespective of used curing system. However, samples cured with sulfur showed a pronounced decrease in mechanical properties.

AB  - In order to minimize emission of formaldehyde from urea formaldehyde resins (UF) and to improve their thermo-oxidative behavior, the effect of low gamma-irradiation on hydrolytic and thermo-oxidative stability of nano-silica modified UF resin, modified UF resin with wood flour (Pinus silvestris L.) as natural filler and modified UF resin with mixture of SiO2/WF fillers were investigated. The hydrolytic stability of modified UF resins was determined by measuring the mass loss and liberated formaldehyde concentration of modified UF resins after acid hydrolysis. The studied modified UF resins have been irradiated (50 kGy) and effect of gamma-irradiation was evaluated on the basis of percentage of liberated formaldehyde before and after irradiation. The minimum percentage (1.23%) of liberated formaldehyde and mass loss of a 25.35% were obtained in wood flour modified UF resin after 7-irradiation which indicate significant improvement in the hydrolytic stability compared to other modified UF resins. The effect of gamma-irradiation was evaluated also on the basis of thermo-oxidative behavior of the same modified UF resins before and after irradiation. The thermo-oxidative behavior was studied by non-isothermal thermo-gravimetric analysis (TG), differential thermo-gravimetly (DTG) and differential thermal analysis (DTA) supported by data from IR spectroscopy. After gamma-irradiation, the shift of DTA peaks a higher temperature indicates that thermo-oxidative stability of modified UF/SiO2/WF is increase. (C) 2014 Elsevier Ltd. All rights reserved.

AB  - Opalized white tuff (OWT) with 40 mu m average particle size and 39.3m(2)/g specific surface area has been introduced into polyisoprene rubber (NR). Their reinforcing effects were evaluated by comparisons with those from precipitated silica (PSi). The cure characteristic, apparent activation energy of cross-link (E-ac) and reversion (E-ar), and mechanical properties of a variety of composites based on these rubbers were studied. This was done using vulcanization techniques, mechanical testing, and scanning electron microscopy (SEM). The results showed that OWT can greatly improve the vulcanizing process by shortening the time of optimum cure (t(c90)) and the scorch time (t(s2)) of cross-linked rubber composites, which improves production efficiency and operational security. The rubber composites filled with 50 phr of OWT were found to have good mechanical and elastomeric properties. The tensile strengths of the NR/OWT composites are close to those of NR/PSi composites, but the tear strength and modulus are not as good as the corresponding properties of those containing precipitated silica. Morphology results revealed that theOWT is poorly dispersed in the rubber matrix. According to that, the lower interactions betweenOWT and polyisoprene rubber macromolecules are obtained, but similar mechanical properties of NR/OWT (100/50) rubber composites compared with NR/PSi (100/50) rubber composites are resulted.

AB  - Two types of nanosilica-based urea-formaldehyde (UF) hybrid materials with formaldehyde to urea (F/U) ratio (0.8) were synthesized without (UF + SiO2) and with coumarin (4-chloro-3-nitro-2H-chromen-2-one). Obtained composites have been irradiated (50 kGy) and their radiation stability was evaluated on the basis of thermal behavior before and after irradiation. The thermal properties of materials were studied by nonisothermal thermogravimetric analysis, differential thermal gravimetry, differential thermal analysis and differential scanning calorimetry supported by data from infrared spectroscopy. The free formaldehyde percentage was determined for all prepared samples. The shift of temperature values for selected mass loss to a high temperature indicates the increase in thermal stability of materials with coumarin after gamma-irradiation. The free formaldehyde percentage was reduced after irradiation from 15% to 3% for sample without coumarin and from 7% to 4% for sample with coumarin. The asymmetric stretching vibrations of -N-CH2-N- absorption band and nu(as)(Si-O) of siloxane or silicone in FTIR spectra of irradiated coumarin compound are shifted to higher wave number values and confirmed its higher thermal stability.

AB  - Acrylonitrile butadiene rubber (NBR) and ethylene-propylene diene monomer (EPDM) rubber compounds have been prepared without and with 50 phr contents of high abrasion furnace carbon black (HAF). Cure characteristics, namely, minimum (M-1) and maximum torque (M-h), scorch time (t(s2)), the optimum cure time (t(c90)) and the cure rate index (CRI) have been investigated. Prepared compounds have been subjected to gamma radiation doses up to 200 kGy to induce radiation crosslinking and degradation process under atmospheric conditions. Mechanical and physical properties, namely, tensile strength (TS), elongation at break (Eb), hardness (Sh-A), Flory-Huggins parameter (chi), the crosslink density (nu) and the molecular weight of the rubber between two crosslinks ((M) over bar (c)) have been followed up as a function of irradiation dose. The morphology investigations of prepared compounds were carried out using SEM micrograph. The results obtained indicate that improvement to irradiation has been attained in different properties of carbon black reinforced NBR and EPDM rubber compounds with respect to unloaded ones.

AB  - The nonlinear viscoelastic behavior of the composites of rubber filled with carbon black, silica, carbon nanotube (CNT), clay and surface-modified nanosilica were studied. The behavior of carbon black-filled rubber is thoroughly analyzed with the intention of developing a constitutive model able to reproduce both static and dynamic material responses. Several nonlinear viscoelastic models have been examined thoroughly and for each of them advantages and disadvantages are highlighted. A series of experiments concerning both static and dynamic tests were performed aimed at measuring all the relevant nonlinear effects. Temperature and strain rate dependencies were investigated and discussed. The standard methodology was applied to perform both tensile and compressive quasi-static tests. Some shortcomings of this procedure, resulting in a unreliable stress-strain constitutive curve around the undeformed configuration, were identified. This lead to the design a non-standard cylindrical specimen able to bear both tensile and compressive loading. Consequently, the influence of the shape factor was removed and the same boundary conditions, in tension and compression, were applied. This allowed the stiffness around the undeformed configuration to be evaluated in detail. The quasi-static experimental results also allowed the influence of the Mullins effect on the quasi-static response to be investigated: during the loading cycles, there is a significant reduction in the stress at a given level of strain, which is a consequence of the internal material rearrangement, i.e., the Mullins effect. This damage phenomenon is sometimes reported to induce transverse isotropy in the material, which is usually assumed to be isotropic. The Payne effect becomes more pronounced at higher silica loading. The filler characteristics such as particle size, specific surface area, and the surface structural features were found to be the key parameters influencing the Payne effect. A nonlinear decrease in storage modulus with increasing strain was observed for unfilled compounds also. The results reveal that the mechanism includes the breakdown of different networks namely the filler-filler network, the weak polymer-filler network, the chemical network, and the entanglement network. The model of variable network density proposed by Maier and Goritz has been applied to explain the nonlinear behavior. The model fits well with the experimental results. The interaction between epoxidized elastomeric matrix and silica as filler was extremely improved, even in the presence of very low content of epoxy groups into the polymer chain.

AB  - The thermal stability of organic-inorganic composites prepared by a twostage
polymerization of urea-formaldehyde resin (UF) with micro- and
nano-TiO2 before and after irradiation has been investigated. Composites of
urea-formaldehyde and particles of TiO2 of different size were synthesized,
namely: Composite 1 (UF+ micro-TiO2) and Composite 2 (UF + nano-
TiO2). The thermal stability of obtained materials was studied by nonisothermal
thermo-gravimetric analysis (TG), differential thermal
gravimetry (DTG) and differential thermal analysis (DTA). Hybrid
composites based on UF resin have been irradiated (50 kGy) and after that
their radiation stability was evaluated on the basis of thermal behavior. DTG
peaks of both composites are shifted to a higher temperature after
irradiation, but Composite 1 after irradiation shows less change in thermal
behavior than Composite 2.

AB  - Three types of nanosilica-based urea-formaldehyde (UF) hybrid composite materials with a formaldehyde-to-urea (F/U) ratio of 0.8 were synthesized (UF with SiO(2)Resin 1, UF+SiO2+thiourea [TU]Resin 2 and UF+SiO2+thiosemicarbazide [TSC]Resin 3). The thermal behavior of obtained materials was studied by nonisothermal thermogravimetric analysis (TGA), differential thermal gravimetry (DTG), differential thermal analysis (DTA) and differential scanning calorimetry (DSC) and supported by data from Fourier transform infrared spectroscopy (FTIR). Nanosilica-based UF hybrid composites have been irradiated (50kGy) and after that their radiation stability was evaluated on the basis of thermal behavior. The percentage of free formaldehyde in all prepared samples was determined. DTG peaks of unmodified nanosilica-based UF resin (UF with SiO2) are shifted to a high temperature. The minimum percentage values of free formaldehyde (3%) for samples based on UF with SiO2 and UF+SiO2+TSC after irradiation dose of 50kGy are detected.

AB  - In this study, the effect of gamma-rays on the mechanical and thermal properties of polymer composites based on chlorinated isobutylene-isoprene rubber/chlorosulphonated polyethylene rubber blend with varying contents of carbon black (CB) filler was investigated. The samples were irradiated at ambient conditions with 100, 200 and 400kGy radiation doses. Tensile strength and hardness are increasing with CB content and radiation dose is increasing, while elongation at break is decreasing. Loss of mass of 0.5, 10 and 30% was calculated for the samples from their respective thermogravimetric curves. The thermal stability of the nanocomposites was improved by both the degree of loading with filler and the cross-linking induced by gamma-irradiation.

AB  - Biogenic silica (BSi) was added at different ratios to some polymer blends of polyisoprene rubber (NR) and chlorosulphonated polyethylene rubber (CSM) cured by conventional sulfur system. The reinforcing performance of the filler was investigated using rheometric, mechanical and swelling measurements, differential scanning calorimetry (DSC), thermogravimetric (TGA) and scanning electron microscopy (SEM) analysis. There was a remarkable decrease in the optimum cure time (t(c90)) and the scorch time (t(s2)), which was associated with an increase in the cure rate index (CRI), with filler loading up to 30 phr in the different blend ratios. The tensile strength and hardness was 4-5 Sh-A higher in the case for the different blend compositions, while the resistance to swelling in toluene became higher. SEM photographs show that the filler is located at the interface between the different polymers which induces compatibilization in the immiscible blends. DSC scans of the filled blends showed shifts in the glass transition temperatures Tg which can be attributed to the improve interfacial bonding between filler and NR/CSM matrix. A higher thermal stability of NR/CSM/BSi composites was detected. (C) 2013 Elsevier Ltd. All rights reserved.

AB  - Blend of polybutadiene (BR) rubber with varying ratios of chlorosulphonated polyethylene rubber (CSM), BR/CSM, keeping the total waste rubber powder (WRP) content constant at 50 phr (parts per 100 rubber) have been prepared on a laboratory-size (300 x 600 mm) two-roll mixing mill maintained at 40 +/- 5 degrees C. The mechanical properties, namely tensile strength (TS), tensile modulus at 100% elongation (M100), elongation at break (Eb%) and hardness have been followed up as a function of irradiation dose (dose rate of 10 kGy h(-1) and total absorbed dose of 100, 200, 300 and 400 kGy) as well as blend composition. The results indicated that the addition of CSM has improved the properties of BR/CSM rubber blends waste rubber powder filled composites. The improvement in mechanical properties of the BR/CSM/WRP (50/50/50) rubber blends is in correlation with homogenous WRP distribution which has been assigned by scanning electron microscopy. Also BR/CSM rubber blends waste rubber powder filled composites are thermally and irradiation more stable than BR and CSM rubbers alone. (c) 2012 Elsevier Ltd. All rights reserved.

AB  - This paper investigates the effect of carbon black filler (CB) (loading 60-100 phr) on the cure kinetics, mechanical properties, morphology and thermal stability of acrylonitrile-butadiene/ethylene-propylene-diene (NBR/EPDM) rubber blends. The determination of cure characteristics was estimated by Monsanto Oscillating Disc Rheometer R-100. Mechanical properties such as tensile strength, elongation at break, modulus at 200% and 300% elongation, hardness, have been measured at room temperature on an electric tensile testing machine (Zwick 1425) according to ASTM D 412. Morphology of the cross linked system was carried out by scanning electron microscope (SEM). The cure kinetics were determined from three temperature rheokinetic curves (T-1 = 160 degrees C, T-2 = 180 degrees C and T-3 = 190 degrees C). From obtained results of NBR/EPDM/CB (80/20/70) composite, a correlation between mechanical properties and calculated activation energy of cross link (E-ac) and reversion (E-ar) process can be concluded. Maximum tensile strength values and synergism for this blend has been observed. The apparent activation energy values (E-a) of degradation were determined by the Kissinger method for NBR, EPDM and NBR/EPDM/CB rubber blend. E-a for the NBR/EPDM/CB rubber blend composite is lower (45.1 kJ/mol) compared to E-a for the rubber based on NBR (156 kJ/mol) and EPDM (75 kJ/mol), which indicates easier formation of rubber blend.

AB  - The non-isothermal degradation processes of acrylonitrile-butadiene and ethylene-propylene-ethylidenenorbornene rubber compounds were investigated with thermogravimetric analysis (TGA) and derivative thermogravimetry (DTG), using the different calculation procedures. It was found that the acrylonitrile-butadiene (NBR) and the ethylene-propylene-diene (EPDM) rubbers degradations represent the complex processes, where there are conversion regions with a constant value of the apparent activation energy (E-a). It was established that NBR and EPDM degradation under nitrogen atmosphere can be described by the one and a half order (n = 3/2) and the first order (n = 1) reaction kinetics, respectively. A linear dependence was observed between lnA and E-a, known as the kinetic compensation effect (KCE). The linear dependence was also established between the change of the entropy Delta S-not equal and E-a, for the formation of the activated complex from the reagents. These dependences are related to assumption that the kinetic mechanisms of the non-isothermal degradation of the NBR and EPDM samples are very similar. (c) 2012 Elsevier Ltd. All rights reserved.
