AB  - A new technology based on bio-templating approach was proposed in this paper. Egg-shell membrane (ESM) has been employed as a natural biotemplate. Fibrous oxide ceramics was prepared by wet impregnation of biological template with water solution of cerium nitrate. The template was derived from membranes of fresh chicken eggs. Repeated impregnation, pyrolysis and final calcination in the range of 600 to 1200 degrees C in air resulted in template burnout and consolidation of the oxide layers. At low temperatures, the obtained products had structure which corresponded to the negative replication of biological templates. Unique bio-morphic CeO2 microstructures with interwoven networks were synthesized and characterized by scanning electron microscope (SEM) and X-ray diffraction (XRD), whereas low-temperature nitrogen adsorption (BET) method was used in order to characterize porous properties.

AB  - Hafnium carbide powder was synthesized by sol-gel polycondensation of hafnium chloride with citric acid. The starting materials were dissolved in water and mixed homogeneously on a hot plate until precursor gel was formed. Pyrolysis of this gel resulted in monoclinic hafnia which after subsequent heat treatment transformed into hafnium carbide. The obtained materials were analyzed by means of X-ray diffraction and scanning electron microscopy. The results showed that the obtained carbide powders were composed of nearly equiaxed particles with narrow size distribution. Characterization by nitrogen adsorption showed that the obtained powders were micro- and mesoporous materials with high specific surface area. (C) 2012 Elsevier Ltd and Techna Group S.r.l.

AB  - The new porous carbon materials were obtained by templating procedure using mesoporous silica (SBA-15) as template. The ordered mesoporous silica materials were synthesized by using Pluronic P123 (non-ionic triblock copolymer, EO20PO70O20). SBA-15/cryogel carbon composites were obtained by sol gel polycondenzation of resorcinol and formaldehyde in the presence of different amount of SBA-15. The polycondenzation was followed by freeze drying and subsequent pyrolysis. One set of SBA-15/sucrose carbon composites was prepared by using sucrose as carbon source. The silica template was eliminated by dissolving in hydrofluoric acid (HF) to recover the carbon material. The obtained carbon replicas were characterized by nitrogen adsorption-desorption measurements, X-ray diffraction and scanning electron microscopy (SEM). It was revealed that the samples have high specific surface (533-771 m(2) g(-1)), developed meso- and micro-porosity and amorphous structure. Porous structure of carbon replicas was found to be a function of the carbon source, properties of SBA-15 and silica/carbon ratio. Room temperature adsorption of nitrogen and adsorption of phenol from aqueous solutions were investigated. (C) 2012 Elsevier Ltd and Techna Group S.r.l. All rights reserved.

AB  - Dense Ce0.8Sm0.1Gd0.1O2-delta electrolytes were fabricated by sintering of CeO2 solid solutions which were prepared from metal nitrates and NaOH using self propagating room temperature synthesis (SPRT). Three different routes were employed to obtain CeO2 solid solution powders: (I) hand mixing of reactants, (II) ball milling of reactants and (III) ball milling of Ce0.8Sm0.2O2-delta and Ce0.8Gd0.2O2-delta solid solutions previously prepared by ball milling of corresponding nitrates and NaOH. Density measurements showed that ball milling, which is more convenient than hand mixing, is an effective way to obtain almost full dense samples after presureless sintering at 1550 degrees C for 1 h. These samples had larger grain size and consequently higher conductivity than the samples obtained by hand mixing. The highest conductivity of 2.704 x 10(-2) (Omega cm)(-1) was measured at 700 degrees C in a sample prepared by route II. It was found that reduced grain size in samples obtained by hand mixing leads to a decrease in grain boundary conductivity and therefore decrease in the total conductivity. The results showed that mixing of single doped ceria solid solutions improved densification and inhibited grain growth. (C) 2012 Elsevier Ltd and Techna Group S.r.l. All rights reserved.

AB  - Porous CeO2 was obtained by bio-inspired route using egg shell membranes (ESM) as a template. ESM extracted from the fresh chicken eggs were washed with distilled water and immersed in solution of Ce(NO3)(3) x 6 H2O for seven days. Samples were subsequently thermally treated at temperature ranging from 600 to 1200 degrees C in argon and air.To study the crystallization process, samples were heated to temperature ranging from 600 to 1200 degrees C, in air, at different temperatures (600, 800, 1000 and 1200 degrees C). Samples were characterized by nitrogen adsorption measurements, X-ray diffraction (XRD) and scanning electron microscopy (SEM). XRD of samples revealed that well crystallized CeO2 is obtained even at temperature as low as 600 degrees C. SEM images confirmed that morphology of obtained CeO2 is a replica of the morphology of the original ESM.

AB  - Hafnium carbide powder was synthesized by sol-gel polycondensation of hafnium chloride with citric acid. The starting materials were dissolved in water and mixed on a hot plate until a precomposite gel was formed. Pyrolysis of these gels resulted in monoclinic hafnia and cubic hafnium carbide materials, which after subsequent heat treatment completely transformed into hafnium carbide. The obtained materials were analyzed by means of X-ray diffraction and electron microscopy investigations. The results showed that the obtained carbide powder was composed of nearly equiaxed particles of narrow size distribution. Characterization by nitrogen adsorption showed that the precomposite gels and the composite powders were micro and mesoporous materials with high surface areas.

AB  - The ordered mesoporous silica SBA-15 materials were synthesized using Pluronic P123 (non-ionic triblock copolymer, EO20PO70O20), under acidic conditions. SBA-15/carbon cryogel composites were obtained by sol gel polycondensation of resorcinol and formaldehyde followed by freeze drying, and subsequent pyrolysis, in the presence of different amounts of SBA-15. For comparison purpose, SBA-15/carbon composite was also prepared using sucrose as carbon source. These materials were characterized by room temperature nitrogen adsorption-desorption measurement, X-ray diffraction, scanning electron microscopy (SEM) and Fourier transform infrared (FT-IR) spectroscopy. It was revealed that the samples have amorphous structure, high specific surface area (350-520 m(2) g(-1)) and developed meso- as well as microporosity. The porosity of structure depends on the carbon source and Si/C ratio which can be easily controlled by varying concentration of starting solution. (C) 2012 Elsevier Ltd and Techna Group S.r.l.

AB  - Coniferous wood (fir) was transformed by pyrolysis into carbon preforms, which were subsequently converted into biomorphic ceramics by the pressure infiltration technique with colloidal silica. An in situ reaction between the silica and the carbon template occurred in the cellular wall at a high sintering temperature. Depending on the employed atmosphere, non-oxide (SiC) or oxide (SiO2) ceramics were obtained. The morphology of the resulting porous ceramics and their phase composition were investigated by scanning electron microscopy (SEM/EDX) and X-ray diffraction (XRD). The experimental results showed that the biomorphic cellular morphology of the wood maintained in both the SiC and silica ceramics, which consisted of only the beta-SiC phase and SiO2, respectively.

AB  - In this paper the possibility of using diatomaceous earth as Si precursor for low temperature synthesis of silicon carbide (SiC) by carbothermal-reduction reactions was studied. A diatomaceous earth of Serbian origin and carbon black as reducing agent were used. The green bodies with constant C/SiO2 ratio (C/Si = 4) were heated at temperatures between 1,250 degrees C and 1,550 degrees C with controlled Ar flow atmosphere. Phase evolution was followed as a function of annealing time and sintering temperature. It was found that reaction proceeded via many intermediate phases. The comparatively low reaction temperature is attributed to the nano-porous nature of the raw material. By means of XRD and SEM investigations powders have been characterized. The results show that diatomaceous earth can be very effective source for obtaining of silicon carbide powders.
