Abstract
The main focus of this review is a new class of neutral molecules containing chemically bonded rare gas atoms. These compounds are given by the general formula HRgX, where Rg denotes a rare gas atom and X denotes an atom or group of atoms having high electron affinity. They are usually produced by photolysis of a HX precursor in low temperature rare-gas matrices. These novel compounds are highly polar and form weakly bound metastable complexes with other molecules via non-covalent interactions. In this review, we discuss theoretical studies of the structure, bonding, properties and factors influencing the energetic stability of these rare-gas species, the preparation and vibrational spectroscopy of these molecules and some theoretical approaches to understanding the nature of these molecules, with experimental studies discussed where appropriate. The complexes formed by the rare-gas compounds exhibit unusual structural and spectroscopic features, which are also discussed in the review.

Advances of Heterocyclic Chemistry with Pesticide Activity
Global food safety and security will continue to be a global concern for the next 50 years and beyond. Plant diseases have had a significant impact on food safety and security throughout the entire food chain, from primary production to consumption. While conventional chemical pesticides have been traditionally used for ...read more
Calculation design of covalent/metal organic framework based catalysts
This research area combines theoretical computation and screening with machine learning for the design of covalent/metal organic framework-based catalysts, bridging the disciplines of organic chemistry, physical chemistry, computational chemistry, materials science, and machine learning. It covers several critical aspects: designing and synthesizing organic catalysts for improved performance, applying computational methods ...read more
Carbohydrates conversion in biofuels and bioproducts
Biomass pretreatment, hydrolysis, and saccharification of carbohydrates, and sugars bioconversion in biofuels and bioproducts within a biorefinery framework. Carbohydrates derived from woody biomass, agricultural wastes, algae, sewage sludge, or any other lignocellulosic feedstock are included in this issue. Simulation, techno-economic analysis, and life cycle analysis of a biorefinery process are ...read more
Catalytic C-H bond activation as a tool for functionalization of heterocycles
The major topic is the functionalization of heterocycles through catalyzed C-H bond activation. The strategies based on C-H activation not only provide straightforward formation of C-C or C-X bonds but, more importantly, allow for the avoidance of pre-functionalization of one or two of the cross-coupling partners. The beneficial impact of ...read more
