Teeth bleaching is one of the treatments for teeth discolouration. Teeth bleaching can do in-home or in-office. The material for that use in-office bleaching is 35% hydrogen peroxide. Hydrogen peroxide is a chemical compound that is tough and has a micro ... see more

One of the most promising materials for storing hydrogen in solid state would be included in metal-carbon composites. In order to obtain nanocrystalline metal particles encapsulated by crystalline or amorphous carbon, mechanosynthesis of zirconium-carbona... see more

Kulit singkong merupakan bahan alami dengan kandungan selulosa mencapai 33.33%. Dalam rangka pemanfaatan kulit singkong sebagai alternatif polimer alam maupun energi terbarukan, maka diperlukan proses delignifikasi untuk memisahkan selulosa dari hemiselul... see more

This work is devoted to the study of the activity of monometallic (Fe/Al2O3) and bimetallic (Fe-Mo/Al2O3) catalysts supported to carrier ?- Al2O3. It has been discovered that the bimetallic catalyst is more active than the monometallic catalyst in the met... see more

The use of liquid hydrogen as a fuel will be inevitable in the aviation of the future. This statement means that manufacturers will also implement liquid hydrogen for cooling all superconducting aviation equipment of an electric propulsion system. The dev... see more

In relation to the main element of the hydrogen storage and supply system based on the hydro-reacting composition – the gas generator – an algorithm for its control has been developed. The development of such an algorithm is carried out in three stages. A... see more

This paper presents the results of a study on the catalytic activity and selectivity of nickel and palladium catalysts in hydrogenation reactions of nitro- and acetylene compounds. It was shown that the activity and selectivity of nickel catalysts in the ... see more

The aim of this study was to obtain new catalysts for the processing of carbon-containing polymer waste based on polyethylene and polypropylene, represented mostly by lids from beverages bottled in plastic containers, which accumulate in huge quantities i... see more
