Closed‐Loop Recyclable Solid Polymer Electrolytes via Dynamic Lipoate Cross‐Linking

open access: yesAngewandte Chemie, EarlyView.
A visible‐light‐driven, closed‐loop recyclable solid polymer electrolyte is built from a bio‐derived lipoate cross‐linker, poly(ethylene glycol) bis(lipoate) (PEG‐LP2), synthesized from α‐lipoic acid. Dynamic disulfide exchange enables efficient DBU‐catalyzed depolymerization and photo‐repolymerization, regenerating membranes that retain high ionic ...

Pesticide MRLs as Trade Barriers: Evidence From Vietnam's Coffee and Rice Exporters

open access: yesAgribusiness, EarlyView.
ABSTRACT As tariffs have declined globally through bilateral and regional trade agreements, food safety standards have emerged as significant determinants of agricultural trade flows. This study examines the impact of maximum residue limits (MRLs) for five pesticides—Azoxystrobin, Chlorpyrifos, Chlorantraniliprole, Clothianidin, and Cyhalothrin—on ...

Engineering BN‐Doped Open‐Shell Polycyclic Hydrocarbons for Enhanced Photothermal Conversion and Therapy

open access: yesAngewandte Chemie, EarlyView.
Two novel bonded BN‐doped polycyclic hydrocarbons BN‐Dira and BN‐Tetra with open‐shell character were rationally designed and synthesized. Their molecular structures were unambiguously confirmed by crystallographic analysis. Facilitated by their intense absorption in the NIR region, high PCE (83.6%) and good photothermal stability, BN‐Dira and BN‐Tetra

SigmaFormer: Augmenting transformer encoders with COSMO sigma profiles for pure component property prediction

open access: yesAIChE Journal, EarlyView.
Abstract Transformer‐based molecular models pretrained on SMILES strings demonstrate strong performance in property prediction. However, these model often lack explicit integration of molecular surface charge distributions that govern intermolecular interactions such as hydrogen bonding and polarity.

Epsilon/zeta toxin-antioxin systems in gram-negative bacteria [PDF]

open access: yes, 2015
Their genetic repertoire allows bacteria to adapt to constantly changing environments and to survive inhospitable conditions. Such genetic modules are toxin-antitoxin (TA) systems, which increase the survival of a population by inducing dormancy or cell death of a subpopulation of cells.

Real‐Time Multicolor Fluorescence Microscopy via Cross‐Channel Acquisition and Deep‐Learning‐Based Inference

open access: yesAdvanced Intelligent Discovery, EarlyView.
Sequential multicolor fluorescence imaging in dynamic microsystems is constrained by acquisition speed and excitation dose. This study introduces a real‐time framework to reconstruct spectrally separated channels from reduced cross‐channel acquisitions (frames containing mixed spectral contributions).

Deep Learning–Based Extraction of Promising Material Groups and Common Features from High‐Dimensional Data: A Case of Optical Spectra of Inorganic Crystals

open access: yesAdvanced Intelligent Discovery, EarlyView.
We report a novel interpretation method for deep learning models based on feature extraction and clustering. Applying this method to an atomistic line graph neural network (ALIGNN) model trained on optical absorption spectra of 2,681 inorganic compounds obtained from first‐principles calculations, we successfully identify key factors underlying ...

Fluorescent Hydrogel‐Based Strain Sensor With Machine Learning‐Augmented Performance

open access: yesAdvanced Intelligent Discovery, EarlyView.
Fluorescent hydrogel strain sensor based on carbon quantum dots enabling optical readout of deformation through strain‐dependent emission changes, coupled with Random Forest analysis to capture nonlinear fluorescence‐concentration relationships and identify optimal sensing conditions. Hydrogels are ideal matrices for bio‐integrated wearable sensors due
