Tendencies of Coal Industry Development in Ukraine [PDF]
, 2017 Ukraine is a country with vast coal reserves of all grades. The estimated coal reserves in Ukraine are around 4% of the world coal reserves. We have three coal basins located on the territory of Ukraine: Donetsk, Lviv-Volyn and Dniprovsky.

Advanced Functional Materials, EarlyView.Machine learning potential (MLP) enables large‐scale molecular dynamics (MD) simulations, uncovering dynamic surface reconstruction of SnO₂ and SnS₂ under CO₂ reduction reaction condition. The negative dipole moments upon *OCHO adsorption are the primary factors driving the leftward shift of the volcano plot.

Annals of Coal Mining and the Coal Trade [PDF]
Nature, 1905 IN a former volume (noticed in NATURE, vol. lix. p. 337) the author carried his annals of coal I mining down to the period of the Select Committee of the House of Commons on Accidents in Mines in 1834. He now continues the subject to the passing of the Coal Mines Inspection Act of 1850, and to the establishment of the Royal School of Mines. This volume,

Coking coals of the Arctic zone of Russia
Georesursy, 2019 Rational and cost-effective development of the richest hydrocarbon resources of the Arctic region of Russia is impossible without the resumption of solid fuel production. On the Arctic coast of Russia there is the largest base of coking coals of valuable

Coal extrusion in the plastic state [PDF]
, 1977 Continuous feeding of coal in a compressing screw extruder is described as a method of introducing coal into pressurized systems. The method utilizes the property of many bituminous coals of softening at temperatures from 350 to 425 C.

Laser‐Induced Graphene from Waste Almond Shells
Advanced Functional Materials, EarlyView.Almond shells, an abundant agricultural by‐product, are repurposed to create a fully bioderived almond shell/chitosan composite (ASC) degradable in soil. ASC is converted into laser‐induced graphene (LIG) by laser scribing and proposed as a substrate for transient electronics.
