A green and energy-efficient technique for production of porous carbon-mineral chars from agricultural wastes (rice husk, wheat bran) sedimentary carbonaceous feedstocks (high-ash peat, coal) was developed.It is based on partial combustion in fluidized bed a deep oxidation catalyst at low temperatures (465 -600 • C).This yields with an elevated mineral content that depends feedstock used, gaseous products complete oxidation.It found the obtained have developed porosity BET specific surface area ca.50 -170 m 2 g -1 , pore volume 0.05 -0.17 ml•g ash 16 -79 wt.%.They were additionally characterized by TGA FTIR.Their testing as adsorbents heavy metal ions (by example Cu 2+ ) organic dyes methyl green) revealed their adsorption capacities are comparable to those produced conventional pyrolytic approaches.

ABSTRACT Titanium alloys are utilized in many fields of science, engineering, and technology because their superior mechanical tribological properties. The investigation goal is to develop an innovative composite for use the automobile industry by applying additive processes such as selective laser melting reinforcing titanium alloy with bio-silica. Bio-Silica (BS) nanoparticles extracted using agricultural waste Calotropis gigantea reinforcement. Industrial Grade (IGT) nanocomposites employed making bio-silica reinforcement 0, 5, 10, 15%. IGT/BS properties, microhardness, tensile (ultimate yield) strength, compressive were investigated. According investigation's outcomes, 15wt.%IGT/BS had better characteristics. L9 Taguchi's orthogonal array illustrate wear trials. ANOVA used optimize outcomes. was determine ideal process parameters that would result lowest possible rate coefficient friction (COF). findings indicated applied load 30 N, sliding velocity 4 m/s, distance 2000 m may achieve wear. ANOVA, most significant factor (30%) influencing
