AI Article Synopsis

  • - The study explores coarse-grained models of liquids like CH(3)SH, CH(3)CHO, and CHCl(3), focusing on their ability to mimic results from more detailed atomistic models while saving on computational time.
  • - Anisotropic Gay-Berne and electric multipole potentials are used in the coarse-grained approach, showing that it can qualitatively match findings from the atomistic model (AMOEBA force field).
  • - The effectiveness of the coarse-grained model heavily relies on the precise definition of the anisotropic GB particles and the proper selection of EMP sites, making attention to these details critical for accuracy.

Article Abstract

Coarse-grained studies of CH(3)SH, CH(3)CHO and CHCl(3) liquids, based on anisotropic Gay-Berne (GB) and electric multipole potentials (EMP), demonstrate that the coarse-grained model is able to qualitatively reproduce the results obtained from the atomistic model (AMOEBA polarizable force field) and allows for significant saving in computation time. It should be pointed out that the accuracy of the coarse-grained model is very sensitive to how well the anisotropic GB particle is defined and how satisfactorily the EMP sites are chosen.

Three choline chloride (ChCl)-based deep eutectic solvents (DESs) as a new type of green solvents were used for the ultrasound-assisted extraction (UAE) of bioactive compounds from Mentha spicata L. DES containing ChCl and malonic acid (MalA) was selected as the most promising, providing a more effective extraction of antioxidants from spearmint. Response surface methodology (RSM) and a Box-Behnken design (BBD) with three variables, ChCl:MalA molar ratio, water content (WC) in DES, and extraction time (t), were implemented for optimizing the extraction conditions.

HIV-1 remains a global challenge, especially in high-prevalence areas like South Africa. This study explores the relationship between inflammation and metabolism in people with HIV, focusing on immune markers and the tryptophan-kynurenine (Trp-Kyn) pathway. We examined immune markers (hsCRP, suPAR, IL-6, NGAL, and sCD163) and Trp-Kyn metabolites (QUIN, Trp, Kyn, Trp/Kyn ratio, and kynurenic acid) in n = 69 treatment-naive South African people with HIV.

Evaluating the practical utility of endangered plant species is crucial for their conservation. Nevertheless, numerous endangered plants, including Sinocalycanthus chinensis, lack historical usage data, leading to a paucity of guidance in traditional pharmacological research. This gap impedes their development and potential utilization.

ConspectusLight-driven polymerizations and their application in 3D printing have revolutionized manufacturing across diverse sectors, from healthcare to fine arts. Despite the popularized notion that with 3D printing "imagination is the only limit", we and others in the scientific community have identified fundamental hurdles that restrict our capabilities in this space. Herein, we describe the group's efforts in developing photochemical systems that respond to nontraditional colors of light to elicit the rapid, spatiotemporally controlled formation of plastics.

Marine biofouling negatively impacts marine industries and ship navigation. However, current coatings are based on a single antifouling mechanism, which is insufficient to cope with the complex and ever-changing marine environment. Herein, multifunctional antifouling coatings were developed using a material system containing perfluoropolyether and caprolactone chains.
