Accuracy of Discrete-Continuum Solvation Model for Cations: A Benchmark Study
Metal ions play important roles in chemistry, biochemistry, and material sciences. Accurately modeling ion solvation is crucial for simulating ion-containing systems. There are different models for ion solvation in computational chemistry, for example, the explicit model, continuum model, and the discrete-continuum ...
Introduction Metal ions play important roles in chemistry, biochemistry, material, and environmental sciences.1 In these fields, many chemical reactions happen in the liquid phase. Thus, accurate modeling of ion solvation is crucial for simulating ion-containing systems. One method of modeling ion solvation involve...

Scalable Force Fields for Metal-Mediated DNA Nanostructures
: Force fields were developed for metal-mediated DNA (mmDNA) structures, using ab initio methods to parameterize metal coordination. Two mmDNA structures were considered, using cytosine/thymine mismatches with coordinated Ag and Hg metal atoms. These base pairs were parameterized with the proposed computational fram...
Introduction The programmable self-assembly characteristics of DNA render it an optimal platform for fabricating nanoscale architectures with precise spatial control and structural versatility.1 Further customizability has been demonstrated with modification of the nucleotides themselves, ranging from modification ...

Esterification of Carboxylic Acids utilizing Eosin Y as a Photoacid Catalyst
: Esters represent a vital functional group in organic chemistry and are prominently featured in valuable molecules. Traditional approaches for ester synthesis from acids typically entail the use of strong acids and toxic activating agents. Photoacid-catalyzed organic synthesis has recently come to the fore in severa...
Introduction Esters are the most fundamental functionalities in organic chemistry considered to be invaluable for pharmaceutical chemistry and other chemical industries. Amongst them, cinnamic esters and α-keto esters are widely prevalent in many biologically active compounds. Traditional methods to synthesize ester...

Prediction of Drug Metabolites Using Neural Machine Translation
Metabolic processes in the human body can alter the structure of a drug affecting its efficacy and safety. As a result, the investigation of the metabolic fate of a candidate drug is an essential part of drug design studies. Computational approaches have been developed for the prediction of possible drug metabolites in ...
Introduction Metabolic processes involve chemical reactions that are mediated by enzymes and take place to sustain life, either by providing energy and building blocks to the cells or by eliminating potentially harmful compounds. Certain enzyme families are responsible for the elimination of xenobiotics, that is compou...

Separation of disaccharide epimers, anomers and connectivity isomers by high resolution differential ion mobility mass spectrometry
Glycans are ubiquitous, structurally diverse molecules that have specific and general roles involving metabolism, structure, and cell-to-cell signalling. Functional specificity depends strongly on the complexity of structures that polysaccharides can adopt based on their subunit composition, length, extent of branch...
Introduction Glycans are of crucial importance in biological systems.1, 2 Most cells in nearly all organisms are adorned with glycans that can have key roles in cell signaling and cell-to-cell recognition. Glycans contribute both generally and specifically to virtually all biological pathways, which can affect dist...
