The core of intermediary metabolism in autotrophs is the citric acid cycle. In a certain group of chemoautotrophs, the reductive citric acid cycle is an engine of synthesis, taking in CO(2) and synthesizing the molecules of the cycle. We have examined the chemistry of a model system of C, H, and O that starts with carbon dioxide and reductants and uses redox couples as the energy source. To inq...

Protein domain motion is often implicated in biological electron transfer, but the general significance of motion is not clear. Motion has been implicated in the transfer of electrons from human cytochrome P450 reductase (CPR) to all microsomal cytochrome P450s (CYPs). Our hypothesis is that tight coupling of motion with enzyme chemistry can signal "ready and waiting" states for electron transf...

With the increasing interest in establishing directional etching methods capable of atomic scale resolution for fabricating highly scaled electronic devices, the need for development and characterization of atomic layer etching processes, or generally etch processes with atomic layer precision, is growing. In this work, a flux-controlled cyclic plasma process is used for etching of SiO2 and Si ...

Correction for ‘On the environmental competitiveness of sodium-ion batteries under a full life cycle perspective – cell-chemistry specific modelling approach’ by Jens F. Peters et al. , Sustainable Energy Fuels 2021, 5 6414–6429, DOI: 10.1039/D1SE01292D.

The chemistry practicum activity in school is impossible due to the COVID-19 pandemic, whereas very important train soft skills and understanding of materials. This research aimed develop 5-e learning cycle-based simple guideline module for students class XI. development model used was a 4-D model. quality product assessed by one material expert, media five reviewers (chemistry teachers high sc...

saeed baghery was born in amol/mazandaran (iran) in 1985. he completed his b.sc. in pure chemistry in 2009 from islamic azad university of amol, mazandaran, iran. he was graduated from m.sc. degree under the supervision of dr. seyed mohammad vahdat in organic chemistry from islamic azad university of amol, mazandaran, iran. he is currently organic chemistry ph.d student under the supervision of...

The Merrifield-Simmons index is one of the most popular topological indices in chemistry and in mathematical properties; there is a correlation between this index and boiling points. The MerrifieldSimmons index of a graph is defined as the total number of its independent sets, including the empty set. This paper proposed an edge grafting theorem operation, which is certain kind of edge moving b...

Ozone depletion results in greater amounts of UV-B radiation that had an impact on terrestrial and aquatic biogeochemical systems. Biogeochemical cycles were the complex interactions of physical, chemical, geological and biological processes that control the transport and transformation of substances in the natural environment and therefore the conditions that humans experience in Earth's syste...

A feature scale simulator for atomic layer deposition (ALD) is presented that combines a Boltzmann equation transport model with chemistry models. A simple but instructive chemistry is considered; one reactant species adsorbs onto the surface, and a second reactant reacts with it from the gas phase (Eley–Rideal). This work includes potential desorption of the adsorbed species during purge steps...
