Published: July 2015

A surprising 20-fold increase in chemiluminescence efficiency was observed for dialkyl luminol derivatives in comparison with the parent compound. This effect could be a direct consequence of steric gearing which facilitates the transition from the intermediate endoperoxide to the electronically excited phthalate. Mechanistic aspects of this process have been supported by computational calculations (CASPT2//CASSCF).

Dual-Anion-Rich Polymer Electrolytes for High-Voltage Solid-State Lithium Metal Batteries.

ACS Nano

Solid polymer electrolytes (SPEs) are promising candidates for lithium metal batteries (LMBs) owing to their safety features and compatibility with lithium metal anodes. However, the inferior ionic conductivity and electrochemical stability of SPEs hinder their application in high-voltage solid-state LMBs (HVSSLMBs). Here, a strategy is proposed to develop a dual-anion-rich solvation structure by implementing ferroelectric barium titanate (BTO) nanoparticles (NPs) and dual lithium salts into poly(vinylidene fluoride) (PVDF)-based SPEs for HVSSLMBs.

Background: In current years, the CRISPR (clustered regularly interspaced short palindromic repeats) based strategies have emerged as the most promising molecular tool in the field of gene editing, intracellular imaging, transcriptional regulation and biosensing. However, the recent CRISPR-based diagnostic technologies still require the incorporation of other amplification strategies (such as polymerase chain reaction) to improve the cis/trans cleavage activity of Cas12a, which complicates the detection workflow and lack of a uniform compatible system to respond to the target in one pot.

Results: To better fully-functioning CRISPR/Cas12a, we reported a novel technique for straightforward nucleic acid detection by incorporating enzyme-responsive steric hindrance-based branched inhibitors with CRISPR/AsCas12a methodology.

This study systematically investigated the effects of ultrasonic treatment timing on the formation and emulsifying properties of chickpea protein isolate (CPI) and citrus pectin (CP) complexes. Results showed that introducing ultrasound during the CPI pre-treatment stage significantly enhanced the emulsifying activity and stability of the complexes. Notably, compared with the independent CPI, the emulsifying activity index of CPIU-CP soared from 0.

The mechanistic understanding of how alkylamines impact Ni-metallophotoredox C-N coupling to form diarylamines remains unclear. In this study, 12-alkylamines were evaluated as additives to determine their effects on the synthesis of diarylamines in a flow photochemical system. Notably, -hexylamine demonstrated the most significant promotional effect.

Porous liquids have traditionally been designed with sterically hindered solvents. Alternatively, recent efforts rely on dispersing microporous frameworks in simpler solvents like water. Here we report a unique strategy to construct macroporous water by selectively incorporating hydrophilicity on the surfaces of hydrophobic hollow carbon spheres (HCS).
