Protein substructure decomposition To represent and analyse 3D substructure composition, we built on Geometricus (v.0.5.0, Python v.3.9)44, and use 16 rotation invariant moments45,46,47 and one chiral invariant moment48. These moments were calculated on α-carbon coordinates for overlapping k-mers...
Synthesis or Direct Combination Reaction - Reactants form a more complex product. Decomposition or Analysis Reaction- A reactant breaks into two or more smaller products. Single Displacement or Replacement Reaction- Also called a substitution reaction, this occurs when the ion from one reactant chan...
Regular patterns can form spontaneously in chemical reaction-diffusion systems under non-equilibrium conditions as proposed by Alan Turing. Here, we found that regular patterns can be generated in uphill-diffusion solution systems without a chemical reaction process through both in-situ and ex-situ obs...
Determine whether or not the following reaction is an example of a decomposition reaction. If not, what type of reaction is it? Li(s) + H2O(l) arrow LiOH(aq) + H2(g) Determine whether or not the following reaction is a single displace...

Brominate (as Br−) in a geothermal reservoir is usually the biochemical indicator for organic decomposition. The higher Br− contents reflect a strong biochemical reaction and the reduction environment, namely a closed system in the geothermal reservoir. Fig.7 indicates the weakly positive correla...
also employed density functional theory (DFT) methods to predict the products, mechanism, and relative rate-determining steps of the decomposition of urea with NiOOH as the catalyst [36]. In their research, three possible pathways were proposed, in which all have the same initial step of urea...
This catalytic reaction has been widely investigated in the various areas for instance elimination of organic pollutants from water through decomposition of contaminants into harmless materials like water, inorganic salts and so on [116], [117]. Fenton reaction in the cancer cells termed ferroptosis,...
a prediction for how to utilize these intrinsic processes to artificially construct the desired specific and functional nanostructures. We try to describe the most directive and effective way to control the structures of nanocrystals for researchers who can master the major reaction mechanism and grasp ...
