AI/ML Enabled High‐Throughput Design and Synthesis for Energetic Molecules

Materials Genome Engineering Advances, EarlyView.
Novel design methods for a special kind of functional molecules — the energetic molecules—are summarized. Both classic Machine Learning (ML) and Artificial Intelligence (AI) generative models are utilized for the high‐throughput design of these energetic molecules, and a sort of high‐energy low‐sensitivity molecules are obtained.

Synergistic Effects of Phenolic Resin and Polymer Architecture on Crosslink Density and Damping in Poly(Epichlorohydrin‐Co‐Ethylene Oxide‐Co‐Allyl Glycidyl Ether) (GECO) Elastomers

Journal of Polymer Science, EarlyView.
Phenolic resin reduces crosslink density and alters the viscoelastic response of GECO elastomers. The magnitude of these changes depends strongly on polymer architecture. Damping performance is governed by the combined effects of network density and molecular structure, not resin content alone, providing a framework for designing advanced vibration ...

Structural and Stability Analysis of de Novo Designed Proteins Incorporating a Plant Self‐Incompatibility Motif

Proteins: Structure, Function, and Bioinformatics, EarlyView.
ABSTRACT Artificial protein design enables the creation of stable scaffolds beyond those evolved in nature. Incorporation of native functional motifs into de novo scaffolds provides a promising strategy to mimic natural interactions while altering structural frameworks.

Coordination chemistry of bicyclic\ud guanidines and guanidinates [PDF]

, 2011
A [5:5] ligand based on the bicyclic guanidine 1,4,6-triazabicyclo[3.3.0]oct-4-ene [Htbo] has been synthesised. Two of these tbo units have been linked via a carbon bridgehead to form a novel bidentate ligand. Based on the knowledge that the electronic properties and specific steric interactions at a metal can lead to new insights into the relationship

Synthetic polymer nanocarrier enhances dsRNA stability but not RNAi efficacy in Brassicogethes aeneus

Pest Management Science, EarlyView.
Experimental setup for dsRNA feeding in Brassicogethes aeneus to evaluate the effect of a synthetic polymer nanocarrier on RNAi efficiency. The experiment assessed whether the nanocarrier enhances RNAi after oral dsRNA delivery. (a) Stability of dsRNA–nanocarrier complexes was tested in simulated gut conditions. (b) Gene expression of αCOP and dre4 was

Exploring the Fragmentation of Sodiated Species Involving Covalent‐Bond Cleavages for Metabolite Characterization

Rapid Communications in Mass Spectrometry, EarlyView.
ABSTRACT Rationale Electrospray (ESI), the most popular desorption/ionization technique used in mass spectrometry‐based metabolomics, generates both protonated and deprotonated molecules, as well as adduct ions, sodium being the most frequent monoatomic cation entering their composition.

Impact of Positively Charged Backbone Modifications on the Properties of Spherical Nucleic Acids

Small, EarlyView.
A synthesis of spherical nucleic acids (SNAs) featuring cationic backbone modifications is presented, together with an analysis of their emerging properties. Introducing positively charged guanidinium groups near the SNA surface enhances cellular uptake and offers a pathway toward more precise control over SNA internalization.
