AB  - Activated carbon is a highly porous and adsorptive material that is widely used for various applications such as wastewater treatment, air purification, and energy storage. Activated carbon can be produced from various raw materials, including biomass, which is a sustainable and renewable resource. The process of producing activated carbon from biomass involves two main steps: carbonization and activation. In the carbonization step, the biomass is heated in the absence of oxygen to convert it into carbon. The resulting carbonaceous material is then activated using a chemical or physical process to create a highly porous structure with a large surface area. One way to activate the carbonized biomass is to use bases as activators. Bases such as potassium hydroxide (KOH) and sodium hydroxide (NaOH) have been used as activators due to their ability to promote the development of micropores and mesopores in the carbon structure. Activated carbon was characterized by various techniques such as scanning electron microscopy (SEM), Brunauer–Emmett–Teller (BET) analysis, Fourier transform infrared (FTIR) spectroscopy and X-ray diffraction (XRD) analysis. These techniques provide information on the surface area, pore size distribution, functional groups, and crystal structure of activated carbon.

AB  - Thermo-chemical conversion via the pyrolysis of cigarette butt (CB) filters was successfully valorized and upcycled in the pre-carbonization and carbonization stages. The pre-carbonization stage (devolatilization) of the precursor material (cellulose acetate filter, r-CAcF) was analyzed by micro-scale experiments under non-isothermal conditions using TG-DTG-DTA and DSC techniques. The results of a detailed kinetic study showed that the decomposition of r-CAcF takes place via complex mechanisms, including consecutive reaction steps and two single-step reactions. Consecutive stages include the α-transition referred to as a cellulose polymorphic transformation (cellulose I → II) through crystallization mechanism changes, where a more thermodynamically ordered system was obtained. It was found that the transformation rate of cellulose I → II (‘cellulose regeneration’) is strongly affected by the presence of alkali metals and the deacetylation process. Two single-step reactions showed significant overlapping behavior, which involves a nucleation-controlled scission mechanism (producing levoglucosan, gaseous products, and abundant radicals) and hydrolytic decomposition of cellulose by catalytic cleavage of glycosidic bonds with the presence of an acidic catalyst. A macro-scale experiment showed that the operating temperature and heating rate had the most notable effects on the total surface area of the manufactured carbon. A substantial degree of mesoporosity with a median pore radius of 3.1695 nm was identified. The presence of macroporosity on the carbon surface and acidic surface functional groups was observed.

AB  - The examination of different raw materials as precursors for obtaining carbon materials is an important area of research due to the wide range of applications for carbon materials in various fields, including energy storage, catalysis, and electronic devices. Some of the commonly studied precursors for carbon materials include biomass, petroleum-based precursors, waste materials, natural materials. The selection of a precursor material depends on various factors, such as the intended application of the carbon material, the availability and cost of the precursor, and the properties of the resulting carbon material. Different precursors can result in carbon materials with varying structures, porosities, and surface chemistries, which can affect their properties and performance in different applications. In our work, we used cherry pits, sour cherry, vineyard peach pits, bean and pea husks. The properties of the initial precursors were tested and then they were treated physically and chemically at different temperatures and times. Correlation of the properties between the initial and final samples was made, as well as their potential application in relation to the obtained properties.

AB  - IQOS (I-Quit-Ordinary-Smoking) is a brand of heated tobacco. It is an alternative to traditional cigarettes, which involves heating tobacco rather than burning it. IQOS devices heat tobacco sticks, called HEETS or HeatSticks, to a temperature that is high enough to release nicotine and flavor, but not high enough to produce smoke. After consuming IQOS, we treated the remains of HEETS with pyrolysis at 800 degrees. In this way, we have protected the environment from pollution, and in addition, we have obtained carbon material, which further has various applications. The obtained final product was tested using different methods and based on the tested properties, it can be said that the material can potentially be used as an energy fuel, a supercapacitor, for the removal of organic compounds, a drug carrier, etc.

AB  - Brassinosteroids (BRs) are a class of plant hormones that play important roles in regulating various physiological and developmental processes in plants. One of the most effective BRs involved in modulating crop growth is 24-epibrassinolide (24-EBL). The effects of different concentrations of 24-EBL on various biochemical and biophysical parameters critical to early growth stages and seedling development were investigated using two maize hybrids, ‘ZP 434’ (a new-generation hybrid) and ‘ZP 704’ (an older-generation hybrid). The evaluation of results is based on measurements of germination percentage, morphometric parameters, redox status, comparative analysis of thermodynamic parameters (such as Gibbs free energy, enthalpy, entropy), and the concentration of specific sugars in different parts of maize seedlings. The results indicate that the germination and initial growth of maize seedlings are influenced by the flow of crucial sugars from the remaining seed (as a source of nutrients) towards the plumule and radicle (as sink organs). Furthermore, alterations in Gibbs free energy play a significant role in these sugar transfers within the maize seedlings. The seed germination was most affected by the highest concentrations of 24-EBL, showing inhibitory effects, whereas lower and moderate concentrations of exogenously added 24-EBL exhibited a beneficial influence on the initial phases of seedling growth. The mentioned approach gives new insights into source–sink relationships and can be used as a quantitative measure of the germination energy, which until now has been a qualitative criterion in seed science.

AB  - This paper presents the results for gross alpha and gross beta activity in leaves samples: Fig (Ficus carica), Vine (Vitis vinifera L.), and Apricot (Prunus armeniaca). Samples were collected in Iraq (Sulaymaniyah, Kurdistan region), and in the Serbia (Belgrade), in the summer 2018. The analysis was done in dried and milled samples as well as in the annealed samples, using gas flow proportional counter. Determination of gross alpha and gross beta activity presents rapid method, essential for the analysis of radioactivity in environmental samples. The gross alpha activity is defines as the total activity of alpha emitters, and originates from the decay chains of 238U and 232Th, which quantity depends on the geological and geographical formation of natural radionuclides. The main contributor to the gross beta activity is natural long-lived isotope 40K, as well as 210Pb, 228Ra. The gross beta measurements also include a contribution from anthropogenic radionuclides 137Cs and 90Sr. Radionuclides that emitting low-energy beta radiation (3 H and gaseous or volatile radionuclide such as iodine) cannot be detected by gross beta activity measurements.

AB  - This paper presents distribution and seasonal variations of tritium, radioactive isotope of hydrogen, in Sava River in Belgrade. Tritium besides its natural origin also has an artificial origin, through human activity including the operation of nuclear power plants, nuclear weapons manufacturing and atomic bomb tests. Knowing the concentration of tritium in the Sava River in Belgrade is important because it is located downstream from the Krško Nuclear Power Plant in Slovenia. Analysis of tritium concentrations in surface water samples were done in composite monthly samples during 2017-2022. Tritium activity was determined by liquid scintillation spectrometer using electrolytic enrichment. Seasonal variations were estimated by determination of average monthly concentrations and seasonal indices.

AB  - The work presents findings from our and other researcher investigations, carried out on different cultivars using some non-standard fertilizers (preferentially based on plant phytohormones, amino acids ant plant and other extracts). The work demonstrates that these non-standard fertilizers is highly effective in biofortification (increasing the nutritional value of food of plant origin) in different crops. Also, natural origin of these non-standard fertilizers makes it suitable for use in organic agriculture. Furthermore, it also contributes to improving yield and different plant physiological and growth parameters. Additionally, that non-standard fertilizers induce excellent resistance crops to abiotic stresses connected with heavy metals and other toxic elements, which makes them suitable for the program of phytoremediation of polluted soil.

AB  - Cigarette butts (CBs) are the most common type of litter on earth, with an estimated 5.5 trillion discarded annually. Apart from being unsightly, CBs pose a serious threat to living organisms and ecosystem health when discarded in the environment because they are toxic to microbes, insects, fish and mammals. In spite of the CB toxic hazard, no studies have addressed the effects of environmental conditions on CB decomposition rate. Numerous proposals have been made to prevent or mitigate cigarette butt pollution, but none has been effective; unsurprisingly, several studies have reported that CBs are the most common item retrieved by clean-up activities in public areas such as beaches and parks. The aim of this study was to collect a certain quantity of CBs, to examine the raw CB, their composition and properties, and then translate them into carbon material as a source of carbon, and as such material also examine the properties and its potential application, and therefore contribute to the preservation of the environment. Physicochemical properties of raw and carbonized CBs were studied by using element analysis, XRD (x-ray diffraction), Fourier-transform infrared (FTIR) spectroscopy, Field emission scanning electron microscopy (SEM), X-ray fluorescence (XRF) analysis.

AB  - The essence of this study is synthesis of a newly developed and efficient heterogeneous catalyst based on aluminum oxide support promoted with potassium iodide (KI) as active dopant responsible for pronounced catalyst activity. Modified sol–gel, reflux and hydrothermal method were used for synthesis of aluminum-oxide support using aluminum isopropoxide as a precursor. The γ-Al2O3 support and KI/γ-Al2O3 catalyst samples were examined by various experimental techniques. Effects of several operational parameters were considered and those are: methanol to sunflower oil molar ratio, catalyst loadings, reaction time and reaction stirring rate. The obtained results indicated that modified sol–gel method for synthesis of γ-Al2O3 catalyst support is the most favorable for obtaining the catalyst with superior catalytic performances in transesterification of sunflower oil. A maximum conversion (triglycerides to methyl esters) of 99.99% was achieved using the SG-KI/γ-Al2O3-770 catalyst under following optimal process parameters: 15:1 methanol to sunflower oil molar ratio, 2.5 wt% catalysts loading, 600 rpm stirring rate and 4 h of the reaction run.

The precursor was first treated with hydrothermal synthesis and then mechanochemically activated with various hydroxides and finally carbonization was done to promote activation.It can be concluded that by acting of different hydroxides (NaOH, BaOH, LiOH, KOH) in the same mass ratio and using the same precursor and the same process, totally different materials with different structure and morphology are obtained.The initial composition of the precursor as well as the final product (active carbon materials) were analyzed using a proximative and ultimate method. The active area surface, volume and pore size was determined using the BET method. Verification of surface-active reaction groups in the identified structures was carried out through Fourier-transform infrared (FTIR) spectroscopy. Morphology of resulting activated carbon materials has been investigated by scanning electron microscopy (SEM) and X-ray diffraction (XRD). The application of the obtained materials is reflected in the fact that we removed the waste, we prevented the pollution of nature, and on the other hand we have obtained material that can be used for various purposes, for example, air and water filters, heating briquettes, fertilizer for plants, superconductors, etc.

In order to improve the performances of cono block, a selection of particle size from 1 mm to 40 mm of hemp shiv was made. The optimization of the mass ratios of the components was also done. The results show that there is a positive effect of reducing the dimensions of the hemp shiv particles on the mechanical properties of the formed cono block. Also, there is a significant influence of the mass ratio of the components on the mechanical properties of the obtained cono blocks.

AB  - Otpad od cigareta u vidu opuška je jedan od najviše zastupljenih oblika otpada na svetu. U sebi sadrži više od 5000 toksičnih sastojaka i hemikalija koje predstavljaju ozbiljan rizik po zdravlje divljih životinja, ljudi i morskih i slatkovodnih organizama. Svake godine se širom sveta proizvedu milijarde cigareta, što rezultira akumulacijom više tona toksičnog otpada. U zavisnosti od uslova okoline i vremenskih prilika, celuloznim acetatnim filterima može biti potrebno i do 10 godina da se u potpunosti razgrade i za to vreme u okolinu konstantno ispuštaju teške metale i toksične hemikalije. Iako moguće metode odlaganja sakupljenih opušaka od cigareta uključuju spaljivanje i odlaganje na deponije, tehnike mogu rezultirati ispuštanjem opasnih isparenja i mogu biti skupe. Obrada i recikliranje opušaka i njihova konverzija u različite materijale bi mogli biti potencijalno rešenje za nastalo zagađivanje životne sredine. Do objavljivanja ovog pregleda postoji nekoliko studija i radova o reciklaži opušaka sa ohrabrujućim rezultatima i u određenom broju istih su proučavane metode, uključujući recikliranje opušaka u asfaltnom betonu i pečenoj cigli, kao izvor ugljenika, materijal koji apsorbuje zvuk, inhibitor korozije, nosač biofilma i mnogi drugi.
AB  - Cigarette waste in the form of cigarette butts is one of the most common forms of waste in the world. It contains more than 5,000 toxic ingredients and chemicals that pose a serious risk to the health of wildlife, humans and marine and freshwater organisms. Billions of cigarettes are produced worldwide every year, resulting in the accumulation of tons of toxic waste. Depending on the environmental conditions and weather conditions, cellulose acetate filters can take up to 10 years to completely decompose, during which time heavy metals and toxic chemicals are constantly released into the environment. Although possible methods of disposing of collected cigarette butts include incineration and landfilling, techniques can result in the release of hazardous fumes and can be expensive. Treatment and recycling of cigarette butts and their conversion into different materials could be a potential solution to the resulting environmental pollution. Until the publication of this review, there are several studies and papers on cigarette recycling with encouraging results and a number of them have been studied methods, including recycling cigarette butts in asphalt concrete and baked brick, as a carbon source, sound-absorbing material, corrosion inhibitor, biofilm carrier and many others.

AB  - In order to clarify relationship between apricot kernel shell biomass slow pyrolysis mechanism and its main constituents (viz. hemicelluloses, cellulose and lignin), the reactivity effects of main constituents on pyrolysis characteristics were determined by the non-isothermal simultaneous thermal analysis. It was found that four-step (parallel) reaction model is suitable for studying the slow pyrolysis process, within the semi-global model which excludes the strong interaction between biomass constituents (pseudo-components). The application of the proposed model was allowed by the results obtained from KAS iterative isoconversional (model-free) approach. The valorization of the model was confirmed by the process optimization. The complex (cumulative) apricot kernel shell pyrolysis rate curves at different heating rates are successfully resolved into the individual decomposition rate curves (arising from thermal conversion of hemicelluloses, cellulose, and primary/secondary lignin fragments) by four-parameter Fraser–Suzuki function. Besides hemicelluloses and cellulose pyrolyses, the proposed model distinguishes primary and secondary lignin reactions, which enhance the gaseous products releasing (primarily CO and CO2 gases) and charification of the solid residue (increased the bio-char yield). © 2020, Akadémiai Kiadó, Budapest, Hungary.

AB  - Polyphenols present in different plant cell organelles increase the resistance of plants to various types of environmental stresses. We investigated the possibility of increasing the content of bioactive compounds in the seed of yellow soybean variety Laura. The soybean was treated during vegetation with five products based on plant extracts, on the assumption of enrichment of plants with various nutrients. Soybean flour extracts were screened spectrophotometrically for total phenolic content and antioxidant activity. The antioxidant activity was evaluated using three methods. The content of phenolic acids was determined by HPLC, and the raw protein content was estimated by the Kjeldahl method. Depending on the treatment, variations in the quantity of individual phenolic acids with up to 90% higher concentration as compared to the control were observed. Controlled usage of certain plant extracts can increase the concentration of the target group of bioactive compounds in the samples. The synergistic effect of proteins and phenolic compounds on the antioxidant activity of extracts was detected. The results of this study are not only important from the aspect of plant resistance to various types of stress, but also when considering soybean as a functional food. © 2019 by the Serbian Biological Society.

AB  - 24-epibrassinolide (24-EBL) is plant steroid hormone that can regulate several physiological effects in plants, including promotion of cell growth and induction of heat stress tolerance. The purpose of this work is to investigate the influence of various concentrations of 24-EBL on the dehydration mechanism of seedlings of two maize hybrids (ZP434 and ZP704). Control and treated samples were subjected to isothermal conditions for dehydration processes. The effects of carbohydrates and mineral contents on the possible changes in the dehydration mechanism (from kinetics standpoint) were investigated. Comparing control samples to samples treated with 24-EBL, it was found that different dehydration mechanisms exist. The differences arise from the influence of 24-EBL, that causes a significant increase of phosphorus values for ZP704, whilst the reverse was identified for ZP434. It was assumed that the plumule sensitivity to dehydration stress originates from the interaction of water with primary amino groups as cations in polyamines, for lower concentrations of 24-EBL. It was found that the temperature variation (105–130 °C) leads to situations where trehalose does not arrive fast enough to “replace the water” because its handicap to binds (by hydrogen bonds) to biomolecules instead of water. It was found that 24-EBL cause changes of carbohydrates properties, which are important for the defense mechanism from environmental stresses. © 2018 SAAB

AB  - Proposed distributed reactivity model of dehydration for seedling parts of two various maize hybrids (ZP434, ZP704) was established. Dehydration stresses were induced thermally, which is also accompanied by response of hybrids to heat stress. It was found that an increased value of activation energy counterparts within radicle dehydration of ZP434, with a high concentration of 24-epibrassinolide (24-EBL) at elevated operating temperatures, probably causes activation of diffusion mechanisms in cutin network and may increases likelihood of formation of free volumes, large enough to accommodate diffusing molecule. Many small random effects were detected and can be correlated with micro-disturbing in a space filled with water caused by thermal gradients, increasing capillary phenomena, and which can induce thermo-capillary migration. The influence of seedling content of various sugars and minerals on dehydration was also examined. Estimated distributed reactivity models indicate a dependence of reactivity on structural arrangements, due to present interactions between water molecules and chemical species within the plant.
