Following conditions were met while carrying out the research: – in terms of their physical properties, natural materials meet the natural conditions; – geometrical parameters of the gasification site are reproduced in the model with the provided principles of static similarity; – lithological structure of the rock coal thickness considers its changes within the deposit area; – hierarchical dependence of the mining and geological factors forming the stress train state of rock mass; – CRMG versatility is provided by the balanced behavior of chemical reactions and physical velocities of the gasification processes.
Research into Dissociation Zones of Gas Hydrate Deposits with a Heterogeneous Structure in the Black Sea.

The presence of such structures altered the thermal properties of the land, changed the energy budget on the ground surface, and changed the surrounding atmospheric circulation characteristics.

Plasma Pretreatment of Spacer The surface modification of feed spacers aims to enhance specific properties by altering the surface chemistry (functionalization).
Notably, plasma polymerization allows for the deposition of monomers that do not require functionalities associated with conventional thermo-chemical polymerization, such as unsaturation or ring structures.

Influence of the pH Value of Comb-shaped Polymer on the Adsorption between the polymer and Ca2+ Ions Guorong Duan1,2,a, Xin Wang1,b, Guohong Huang2,c, Ying Gong2,d 1Key Laboratory for Soft Chemistry and Functional Materials of Ministry Education, Nanjing University of Science and Technology, Nanjing, 210094, China 2Ruidi Engineering & Technology Center, Nanjing Hydraulic Research Institute, Nanjing, 210024 China aduangr2003@yahoo.com.cn, bwangx@mail.njust.edu.cn, cghhuang@nhri.cn, dgymm1984@163.com Keywords: comb-shaped; polymer; conductivity; adsorption Abstract.
Its structure consists of a grafted long-chain macromolecule structure; the backbone chain has large numbers of carboxylic acid groups, the branch chains are nonionic polyglycol structures.
Current studies of comb-shaped polymers mainly focused on the relation between their structure and application; this relationship was often used to propose the practical compositions of this comb-shaped macromolecule.

The chemical structure and crystallographic of calcium phosphate bioceramics are similar to that of natural bone [5].
The positions of these absorption bands groups indicate the crystallinity of the HA structure is formed [33].
