High Temperature Compressive Strength and Creep Behavior of Si-Ti-C-O Fiber-Bonded Ceramics
(Elsevier, 2017)
Fiber bonded silicon carbide ceramic materials provide cost-advantage over traditional ceramic matrix composites and require fewer processing steps. Despite their interest in extreme environment thermostructural applications ...

Compressive strength degradation in ZrB2-based ultra-high temperature ceramic composites
(Elsevier, 2011)
The high temperature compressive strength behavior of zirconium diboride (ZrB2)-silicon carbide (SiC) particulate composites containing either carbon powder or SCS-9a silicon carbide fibers was evaluated in air. Constant ...

Performance improvement in olive stone's combustion from a previous carbonization transformation
(Elsevier, 2018-09)
Under the framework of circular economy, agricultural wastes are an interesting carbon-based feedstock for thermal energy and power generation. Their use could extend the availability of biomass-based fuel and, at the same ...

Monolithic supports based on biomorphic SiC for the catalytic combustion of hydrogen
(Royal Society of Chemistry, 2016)
Catalytic hydrogen combustion was studied with H2/air mixtures in conditions that simulate the H2 concentration of the exhaust gases from fuel cells (3–4% v/v H2 in air). Pt-impregnated monoliths based on porous biomorphic ...

Environmentally friendly monolithic highly-porous biocarbons as binder-free supercapacitor electrodes
(De Gruyter, 2018)
A simple, low-cost and environmentally friendly method has been used to obtain highly porous biomorphic carbon monoliths with a good combination of interconnected macro-, meso- and microporosity, and good electrical ...

Biological strategy for the fabrication of highly ordered aragonite helices: the microstructure of the cavolinioidean gastropods
(Nature Publishing Group, 2016)
The Cavolinioidea are planktonic gastropods which construct their shells with the so-called aragonitic helical fibrous microstructure, consisting of a highly ordered arrangement of helically coiled interlocking continuous ...

Microstructure, elastic and inelastic properties of partially graphitized biomorphic carbons
(MAIK Nauka/Interperiodica, 2015-03)
The microstructural characteristics and amplitude dependences of the Young's modulus E and internal friction (logarithmic decrement delta) of biocarbon matrices prepared by beech wood carbonization at temperatures T (carb) ...

Effect of catalytic graphitization on the electrochemical behavior of wood derived carbons for use in supercapacitors
(Elsevier, 2015)
Porous graphitic carbons were successfully obtained from wood precursors through pyrolysis using a transition metal as catalyst. Once the catalyst is removed, the resulting material mimics the microstructure of the wood ...

Precision and accuracy of stress measurement with a portable X-ray machine using an area detector
(International Union of Crystallography, 2017-02)
The use of portable X-ray stress analyzers, which utilize an area detector along with the newly adopted 'cosα' or full-ring fitting method, has recently attracted increasing interest. In laboratory conditions, these ...
