An assessment of the feasibility of using the existing equipment of a rotary kiln cooler drum for heat treatment of a carbon-containing filler to produce synthesis gas using production waste in the form of a dust fraction of heat-treated petroleum coke or... see more

The physical and chemical properties of products from the carbon-thermal reduction of oxide chromo-containing ore raw materials have been investigated. This is necessary to determine the parameters that reduce the loss of Cr in the processing of ore mater... see more

In the present paper, porous materials were prepared from the hydrothermal treatment of aqueous solutions of tannin, a renewable phenolic resource extracted from tree barks, containing dissolved salts of transition metals: V, Cr, Ni and Fe. Hydrothermal t... see more

Herein, a promising method to prepare efficient N-doped porous carbon-supported Fe2O3 nanoparticles (Fe2O3/N-PCs) ORR electrocatalysts is presented. The porous carbon was derived from a biomass i.e., mulberry leaf through a cost-effective approach. The ex... see more

The eco-friendly brake composite has been still an interesting issue in the development of brake friction materials. Wastes of S. Macrophylla (mahogany) fruit skin and coal fly ash are available as organic ingredients of bio-composite brakes. In this rese... see more

The object of research is the processes of obtaining magnetite particles by the method of chemical condensation with the aim of subsequent use in the conversion of carbon monoxide, which is formed during the combustion of carbon-containing materials in co... see more

This paper addresses the prospects of recycling waste from oil and gas extraction in order to manufacture building materials. The principal possibility has been established to apply the examined samples of drilling sludge as the basic raw material and a m... see more

Smart textiles are fabrics that have been developed or modified with new technologies providing added value to the wearer. The emerging smart textile technologies have to take into account the aesthetics and comfort of the textiles, using at the same time... see more
