“…Irradiating high-energy electrons impacts the chemistry of the suspending medium in liquid cells, such as O 2 , CO 2 , and H 2 O, giving rise to metastable molecules and radicals, such as OH • , O 2 •– , e h – , O 2+ , H 2 O 2 , CO*, H 3 O + , HO 2 • , and 1 O 2 (Figure d). − Ling et al selected environmentally sensitive and widely concerning black phosphorus (BP) nanoflakes as an example to propose an innovative approach for simulating the oxidation–reduction process of solids in the complex environment triggered by ubiquitous free radicals . Free radicals have a crucial impact on the fate of redox-active substances and trigger the corrosion of solid surfaces in the environment.…”

Visualizing the structure and processes in liquids at the nanoscale is essential for understanding the fundamental mechanisms and underlying processes of environmental research. Cutting-edge progress of in situ liquid-phase (scanning) transmission electron microscopy (LP-S/TEM) and inferred possible applications are highlighted as a more and more indispensable tool for visualization of dynamic environmental processes in this Perspective. Advancements in nanofabrication technology, high-speed imaging, comprehensive detectors, and spectroscopy analysis have made it increasingly convenient to use LP S/TEM, thus providing an approach for visualization of direct and insightful scientific information with the exciting possibility of solving an increasing number of tricky environmental problems. This includes evaluating the transformation fate and path of contamination, assessing toxicology of nanomaterials, simulating solid surface corrosion processes in the environment, and observing water pollution control processes. Distinct nanoscale or even atomic understanding of the reaction would provide dependable and precise identification and quantification of contaminants in dynamic processes, thus facilitating trouble-tracing of environmental problems with amplifying complexity.

“…The primary direct detection of CS2 was made 15 years later, in 1995, by comparing the unidentified spectral lines of Comet 122P/de Vico in the UV-Visble region with the experimental spectra of supersonically cooled CS2 [8]. In addition to comets, CS2 has also been observed on planetary bodies such as the Jovian system [9,10], Earth's moon [11], etc.…”

Sulfur Ice Astrochemistry: A Review of Laboratory Studies

Sulfur is the tenth most abundant element in the universe and is known to play a significant role in biological systems. Accordingly, in recent years there has been increased interest in the role of sulfur in astrochemical reactions and planetary geology and geochemistry. Among the many avenues of research currently being explored is the laboratory processing of astrophysical ice analogues. Such research involves the synthesis of an ice of specific morphology and chemical composition at temperatures and pressures relevant to a selected astrophysical setting (such as the interstellar medium or the surfaces of icy moons). Subsequent processing of the ice under conditions that simulate the selected astrophysical setting commonly involves radiolysis, photolysis, thermal processing, neutral-neutral fragment chemistry, or any combination of these, and has been the subject of several studies. The in-situ changes in ice morphology and chemistry occurring during such processing are often monitored via spectroscopic or spectrometric techniques. In this paper, we have reviewed the results of laboratory investigations concerned with sulfur chemistry in several astrophysical ice analogues. Specifically, we review (i) the spectroscopy of sulfur-containing astrochemical molecules in the condensed phase, (ii) atom and radical addition reactions, (iii) the thermal processing of sulfur-bearing ices, (iv) photochemical experiments, (v) the non-reactive charged particle radiolysis of sulfur-bearing ices, and (vi) sulfur ion bombardment of and implantation in ice analogues. Potential future studies in the field of solid phase sulfur astrochemistry are also discussed in the context of forthcoming space missions, such as the NASA James Webb Space Telescope and the ESA Jupiter Icy Moons Explorer mission.
