In this article presented the results of a study on improving mechanical properties composite materials based polyethylene. A composition filled with thermoplastic polymer - polyethylene modified kaolin-graphite filler is proposed, which will allow obtaining high-quality products local raw materials, simplifying material composition, and expanding their performance due to improved strength trib...

The present study focused on developing Alkali Activated Fine Aggregate (AAFA) by palletization method. AAFA was manufactured using Ground Granulated Blast Furnace Slag (GGBS) and alkali activator solution at ambient conditions. Sodium hydroxide of six molarity sodium silicate to ratio 2.5 used. AACA's properties are similar Natural except for flakiness elongation index. water absorption Abrasi...

Alkali activated binders are a promising alternative to the use of Portland cement in manufacture concrete for curbing CO2 emissions. Novel sources silicates have been investigated recent years reducing cost and environmental impacts associated with chemical activators. This study describes production solid sodium silicate (SS) activating powder from bamboo leaf ash (BLA). Bamboo leaves were ca...

Pain has a strong emotional dimension, and the amygdala plays a key role in emotionality. The processing of nociceptive mechanical and thermal information was studied in individual neurons of the central nucleus of the amygdala, the target of the spino-parabrachio-amygdaloid pain pathway and a major output nucleus of the amygdala. This study is the first to characterize nociceptive amygdala neu...

Alkali-activated binders (AABs) stand out as promising candidates to replace ordinary Portland cement (OPC) since waste can be used raw material for their manufacture. This study addresses the environmental feasibility of using weathered bottom ash (WBA) and metakaolin (MK) alkali-activated binder precursors (AA-WBA/MK). Different proportions WBA MK were mixed (100/0, 75/25, 50/50, 25/75, 0/100...

Palladium (II) coordination complexes catalyze the reaction of alcohols with ketones to yield ethers. During the catalytic cycle, the alcohol adds selectively to the β-carbon (anti-Markovnikov). In this work, mechanism and kinetics for the reaction of methanol with methyl vinyl ketone (MVK), being catalyzed by Pd, has been theoretically investigated in detail. Using quantum mechanical approach,...

Activated carbon has many applications in the environment, cosmetology, medicine and industry. The surface of each activated can be modified to obtain desired adsorption properties. Chemical activation greatly affect efficiency, control activity application carbon. aim study was modify selected by chemical physical methods, while maintaining these parameters so that it could used medicine. Powd...
