Predicting and Rationalizing Piezoelectricity in Racemic Bioorganic Molecular Crystals

open access: yesAngewandte Chemie, EarlyView.
Racemic molecular crystals, composed of equal mixtures of chiral enantiomeric components, are predicted to exhibit significant piezoelectric responses and favourable mechanical flexibility. This study identifies organic and bioorganic racemates as promising candidates for sustainable, lead‐free materials, enabling next‐generation applications in energy

An Integrated DNA Nanoprobe for Intranuclear Imaging and in Situ Profiling of OGG1 Activity

open access: yesAdvanced Science, EarlyView.
The TP‐SA nanoprobe, integrating an AS1411 aptamer for nuclear delivery and a FRET array for signal amplification, enables real‐time tracking of nuclear OGG1 activity. It reveals cell‐line‐specific basal OGG1 levels and shows clinical promise using pneumonia patients’ lavage fluid.

Reenvisioning the De Mayo Reaction: A Boron‐Enabled Cycloaddition Approach

open access: yesAngewandte Chemie, EarlyView.
An oxa‐boracycle conformational lock strategy enables photocatalytic [2+2] cycloaddition to afford densely substituted cyclobutylboronates. The conformational constraint suppresses triplet relaxation and promotes productive bimolecular reactivity.

An Overview of Saturated Cyclic Ethers: Biological Profiles and Synthetic Strategies

open access: yesMolecules, 2019
Saturated oxygen heterocycles are widely found in a broad array of natural products and other biologically active molecules. In medicinal chemistry, small and medium rings are also important synthetic intermediates since they can undergo ring-opening and

High Free‐Volume Imidazole‐Based Ionomers for High‐Temperature Proton Exchange Membrane Fuel Cells

open access: yesAdvanced Science, EarlyView.
High free‐volume imidazole‐based ionomers (PF4IM‐72) enable enhanced phosphoric acid uptake and efficient proton transport, delivering peak power densities of 0.645 W cm−2 at 160 °C and 0.838 W cm−2 at 200 °C in HT‐PEMFCs. This work highlights a promising platform for next‐generation ionomers with improved high‐temperature performance and stability ...

Enhancing Interfacial Charge Transport in Gold Nanoparticle@Polyaniline Hybrids via N‐Heterocyclic Carbene Linkers

open access: yesAngewandte Chemie, EarlyView.
An amino‐functionalized NHC‐Au complex is employed as a conductive molecular linker to couple large Au NPs with PANI, yielding Au NP@NHC‐PANI hybrids with an electronically well‐defined interface. SAMs of these hybrids reveal enhanced charge transport compared with Au NP@PANI.

Resistant Peanut Genotype Reprograms Rhizosphere Metabolism to Enhance Bacterial Wilt Suppression

open access: yesAdvanced Science, EarlyView.
The resistant peanut genotype selectively recruits beneficial bacteria, which coincides with the activation of salicylic acid (SA)‐dependent systemic acquired resistance (SAR) against Ralstonia solanacearum. Keystone rhizosphere metabolites are positively correlated with both beneficial microbiome assembly and SAR gene expression.
