Lowering salivary pH with sugar‐containing gum augments salivary nitrite production and blood pressure reduction with dietary nitrate (beetroot juice)

British Journal of Clinical Pharmacology, EarlyView.
Acutely lowering salivary pH (with sugar‐containing acidic gum vs. sugar‐free gum) augments salivary nitrate reduction to nitrite, plasma nitrite concentration, and blood pressure lowering with dietary nitrate. Modifying salivary pH reveals a mechanism by which the nitrate‐nitrite‐NO pathway may be upregulated/inhibited, with potential for other ...

1D/3D Heterojunction for High‐Efficiency Hole‐Transport Layer‐Free Carbon‐Based Wide‐Bandgap Perovskite Solar Cells

Carbon Energy, EarlyView.
By modifying wide‐bandgap high‐Cs perovskite surfaces with quaternary ammonium salts of varying alkyl‐chain lengths, tetrapropylammonium bromide (TPABr) is shown to successfully construct a 1D/3D heterojunction. This structure effectively passivates interface defects and optimizes energy level alignment, achieving a champion efficiency of 20.14% with ...

Synthetic Strategies for Activity‐Based Probes to Decode Ubiquitin‐Like Modifiers

Chemistry – A European Journal, EarlyView.
ABSTRACT Ubiquitin‐like proteins (Ubls) such as SUMO, NEDD8, ISG15, URM1, UFM1, FAT10, ATG8/ATG12, and FUBI are essential regulators of cellular homeostasis, controlling processes from protein stability and trafficking to immune signaling and autophagy.

S‐Doped Carbon Nitride Thin Films From a Triazole Precursor

Carbon Innovation, EarlyView.
Sulfur‐functionalized carbon nitride thin films are synthesized via low‐temperature chemical vapor deposition using a triazole‐derived precursor. Tunable sulfur incorporation modulates electronic and optical properties and enables efficient visible‐light photocatalysis with high conversion and selectivity.
