Producing dried powders from blueberry pomace allows to reduce its environmental impact and gives value to this waste material. This work aims to evaluate the effect of particle size (fine or coarse) of blueberry pomace dried at 70 ºC on its fibre content and main physicochemical properties, including antiradical capacity, total phenols and anthocyanins content, hydration and emulsifying properties. The effect of storage on antioxidant properties was also evaluated. Results showed a significant effect of particle size on fibre content and consequently, on water retention, holding and emulsifying capacity of the powder. Neither phenols nor anthocyanins were affected by particle size or storage time. Keywords: blueberry pomace, powders, fibre, antioxidant properties.

Porous Sic

Polycarbosilane (PCS) and SiC powders, in which PCS acted as binder, were adopted as starting materials to fabricate porous SiC ceramics. During pyrolysis, PCS experienced an organicinorganic transformation and bonded SiC powders at a low temperature of 1273K. The flexural strength of porous SiC ceramics increased with increasing PCS content and shaping pressure, while the porosity decreased with increasing the PCS content, shaping pressure and particle size of SiC powders. The fracture surface of porous SiC ceramics was observed.

The purpose of this research was to fabricate the particle board from the coffee husk. The coffee husk from Chumphon province of Thailand was collected, prepared and separated into four groups such as outer husk, inner husk, the mixture of inner and outer husk and husk from the milling process. The coffee husk particle sheet was formed by the compression molding with the heater. Then the coffee husk particle sheets were the mechanical properties testing. The results showed the coffee husk particle sheet from milling process pass the Thai industrial standard (TIS.876/2547). However, the results of swelling and water absorption indicated that all the coffee husk sheet were not passed the TIS.876/2547. The effect of coffee husk particle size on mechanical properties was clarified. The coffee husk particle sheet from the particle size of 2, 4 and 6 mm was mechanical testing and follow TIS.876/2547. The coffee particle size of 2 mm showed the passing the standard. Moreover, the effect of isocyanate adhesive on mechanical properties was investigated. The weight percentage range of isocyanate adhesive on coffee husk from 7 to 13 %wt was carried out. The weight percentage of 9, 11 and 13 showed according to TIS.876/2547. From the experiment indicated that the coffee husk could be applied to the wood particle board industrial.

Operating Temperatures

Nanocatalytic particles of Gold (Au), Platinum (Pt), and Palladium (Pd) are highly reactive at room-temperature and can be used to generate heat in micro-scale devices for portable power generation. No pre-heating is required for light-off and high steady-state operating temperatures can be sustained with high density alcohol-air premixtures. Preliminary experiments conducted in our lab and those reported by Hu and co-workers at Oak Ridge National Lab have measured peak operating temperatures ∼ 300–500 degrees Celsius using near-stoichiometric methanol/air and ethanol/air premixtures at ambient initial temperature and atmospheric pressure. The effect of particle size, morphology, mass loading, and flow residence time are reported for different mixture stoichiometries. Temperature measurements and gas species analyses are also tabulated. Interestingly, smaller particles were observed to be less reactive than larger particles for the same mass loadings for select conditions. Materials characterization of the particles has also been conducted to characterize the specific surface area of the catalyst and evaluate the importance of particle sintering, morphology changes, and particle distribution.

Biogenic Hydroxyapatite

The work is devoted to investigation of porous glass-ceramic composite materials on the basis of biogenic hydroxyapatite and sodium borosilicate glass prepared from starting powders with different particle sizes (<50 ?m and <160 ?m). Starting hydroxyapatite/glass weight ratio was 1.0/0.46 and sintering temperature was ~800?C. Microstructural characterization of the surface and fracture of the samples revealed a decrease in sizes of grains and pores with decreasing the particle size of the precursor powder. However, porosity of the composites practically did not depend on the particle size and was equal to 32.5-33.0%. The same tendency was observed for the compression strength (66-67MPa). However, investigation of structural-mechanical properties using an indentation method, where dominant load is applied to the surface layers of sample, showed up the effect of the particle size of the starting powder on the mechanical properties of the composites: the smaller particle size, the higher mechanical properties.

Activated carbon also known as activated charcoal is a common term for carbon materials, which comprises charcoal. Activated carbon has a good adsorption capacity against gases and pollutants in liquids because of its wide surface. The material used in this research was tropical black bamboo, with the variation of particle size -10+20 mesh, -20+40 mesh, -40+60 mesh and -60+80 mesh.  There are 2 processes to produce activated carbon, i.e. carbonation and activation. In this research, the carbonation is set at 380°C in 1 hour. Then, each size of carbon was activated by H3PO4 9.8% along 24 hours. The analysis conducted were moisture content, ash content, iodine number, and functional group analysis using Fourier Transform Infrared Spectroscopy (FTIR). The smaller particle size, the more pores will be produced and it caused the surface area higher. The results showed that variation of particle size had effect on the characterization and quality of activated carbon, where moisture content is between 10.60 to 4.05%, ash content is 1% to 0.2% and iodine adsorption is between 710 mg/g to 900 mg/g. In FTIR analysis, it showed that all of the samples had O-H, C=C, and C-O functional group.
