With an increase in the population and industrialization, a lot of valuable natural resources are depleted to prepare and manufacture products. However industrialization on the other hand has waste disposal issues, causing dust and environmental pollution. In this work, Aluminium Metal Matrix Composite is prepared by reinforcing 10 wt% and 20 wt% of wet grinder stone dust particles an industria...

Steel composites reinforced with alumina nanoparticles were prepared by powder metallurgy process. Samples containing two different amounts of carbon (0.35 and 0.55 wt.%) and 0-5 wt.% Al2O3 nanoparticles were fabricated by mixing, compacting and sintering of diffusion bonded Distaloy AE powder. The density, hardness and wear tests were performed on the prepared samples. Fu...

The study analyzed the physical and chemical properties of dry-torrefied (DT) wet-torrefied (WT) biomass. Hemicellulose was mainly degraded by torrefaction, contents glucan lignin were relatively increased. degradation rate biomass higher in WT (18.25%–23.13%) than DT (3.12%–3.83%), it increased with increasing reaction time. Torrefaction improved crystallinity from 36.88% raw material to a max...

I n chemical pulping a large part of the wood is dissolved during digestion. The dry matter content of the generated black liquor is typically 12 to 18 wt% [1, 2]. In the case of kraft black liquors four main groups of organic constituents are present, 30-45 wt% ligneous material, 25-35 wt% saccharinic acids, about 10 wt% formic and acetic acid, and 3-5 wt% extractives. It also contains about 1...

BACKGROUND TRR14 protein is a small protein, a member of a multigene family in Arabidopsis which was found as the fi rst protein during screening seedlings for their resistant to the trehalose sugar. OBJECTIVES A number of TRR14-overexpressing plants were subjected to the characterization in the present research, among which, the associated morphological features and changes accompany growth ...

Tribological characteristics of fine-grained WC–8 wt%Ni with different surface finishing conditions corresponding to sequential wire electrical discharge machining (wire-EDM) or grinding were investigated by performing dry reciprocating sliding experiments on TE77 pin-on-plate equipment with WC–6 wt%Co as mating material. Surface finishes and wear surfaces were characterized using surface topog...

Kinetics of nitrogen release by Daphnia mugna (0.2-0.4 mg dry wt) and Daphnia pulex (ca. 0.03 mg dry wt) were followed by measuring ammonium (plus primary amines) in water flowing past individual animals. Culture media water was pumped slowly (6 ml *h-l) through an incubation chamber (volume 0.05 ml) containing a daphnid and then either mixed with o-phthalaldehyde reagent for continuous analysi...

heterogeneous proton exchange membranes (pem) are synthesized using the dry phase inversion technique. the casting solutions are prepared by dispersing a finely ground cation exchange resin particle in n,n-dimethylacetamide (dmac) solution of polyvinyl-chloride (pvc). results show that ion exchange capacity is increased with the addition of 1 %-wt nanosilica (from 0.14 to 0.27 meq/g) while it i...
