Graphene aerogel (GA) was synthesized by chemical reduction of graphene oxide (GO) using ethylene diamine as a reducing agent, which was then followed by a freeze-drying process. In this work, we produced GA by hydrothermal process followed by freeze-drying. The produced adsorbent was then deployed to study the TC adsorption process.

Ebook "Fundamentals of soil science (8th edition)" revision of a bestselling text shows that soil is three-dimensional and dynamic. This concept is developed in the first two chapters and is built on throughout the book. Chapters 3 through 7 explore soil physical properties and water, with expanded coverage of tillage and traffic and an increased emphasis on water and wind erosion processes. Chapters 8 through 11 discuss the biological aspects of soils as well as their mineralogical and chemical properties.

Ebook "Polycyclic aromatic hydrocarbons: Their global atmospheric emissions, transport, and lung cancer risk" presents a comprehensive analysis of the global health impacts of polycyclic aromatic hydrocarbons (PAHs) in ambient air, conducted on the basis of a high-resolution emission inventory, global chemical transport modeling, and probabilistic risk assessment. One of the main strengths of the thesis is the concentration downscaling process, which provides a linkage between emissions and exposure concentrations at a comparatively high resolution.

In this research, in an attempt to make use of the kaolin resources in Vietnam, we present a synthetic process of zeolite A via hydrothermal from kaolinite, together with the modification process of zeolite A using different metallic cations. The characteristics of the prepared zeolite LTAs such as chemical composition and crystalline structure, as well as their catalytic activity in the methanation reaction of carbon dioxide (CO2) to methane (CH4) were extensively investigated.

Nowadays, supercapacitors have been among popular electrochemical energy storage devices in modern life. Plenty of active materials have been investigated and developed to meet the increasing demands for high-performance supercapacitors. In this study, we introduce a facile chemical synthesis route in combination with a subsequent calcination process to fabricate the oxide/hydroxide composites of nickel (Ni) and copper (Cu) as active materials for highperformance asymmetric supercapacitors.

In porous aquifers, the central-to-sea cross-section highlights meteoric water dominance from rain and surface sources. Groundwater undergoes exchange-absorption with silicate minerals, enriching Ca2+ and Mg2+ (reducing Na+). Seaward, dissolution and leaching of salts in marine-origin sediments (mQ2, mQ13, mQ12-3, and mN22) prevail. The results of this paper provide necessary information for the effective management of groundwater quality.

A major challenge for outdoor uses of methylammonium lead halide (MAPbX3) solar cells is the poor durability of the perovskite film under humidity. This instability is due to limitations of the dipping or spin coating process in producing MAPbX3 films through a direct reaction between PbI2 and methylammonium iodide (MAI) in an organic solvent. In this study, we devised an eco-friendly and cost-effective method to fabricate MAPbX3 films using an aqueous solution of Pb(NO3)2 and MAI vapour. I

A study of the state of the theory of fuzzy sets shows that until recently in Russia there were almost no studies in the chemical sector of the economy and finance using fuzzy analysis and forecasting, although by that time all necessary prerequisites for modeling financial systems had been created. The current situation in Russia is characterized by a high degree of science lagging behind the requests of state and commercial supply chain management.
