Phototauntomerism of o-nitrobenzyl compounds: o-quinonoid aci-nitro species studied by matrix isolation and DFT calculations [PDF]
, 2001 Photolyses of 2-nitrobenzyl methyl ether and 2-nitrotoluene with 254 nm light have been investigated in Ar and N2 matrices at 12 K, and have been found to give o-quinonoid aci-nitro species as the primary photoproducts, along with other products.

High turnover in electro-oxidation of alcohols and ethers with a glassy carbon-supported phenanthroimidazole mediator. [PDF]
, 2017 Glassy carbon electrodes covalently modified with a phenanthroimidazole mediator promote electrochemical alcohol and ether oxidation: three orders of magnitude increase in TON, to ∼15 000 in each case, was observed compared with homogeneous mediated ...

Targeting TNBC: core–shell polycationic polyurea dendrimers with inherent anticancer activity
FEBS Open Bio, EarlyView.Core–shell polycationic PURE dendrimers were tested in TNBC‐derived tumor models. Both formulations selectively targeted TNBC and effectively reduced tumor volume. PUREG4‐OEI48 suppressed tumor growth without detectable toxicity, whereas PUREG4‐OCEI24, despite showing efficacy, induced hepatic toxicity.

Selective Electrochemical Conversion of Biomass-derived Valeric Acid to Ethers/Esters
International Journal of Electrochemical Science, 2018 To quantitatively convert biomass into value-added chemicals or biofuels is still a great challenge. Herein, we develop an efficient electrochemical method to convert the biomass-derived valeric acid into ethers (butyl methyl ether and butyraldehyde ...

Advanced Functional Materials, EarlyView.This study presents novel anti‐counterfeiting tags with multilevel security features that utilize additional disguise features. They combine luminescent nanosized Ln‐MOFs with conductive polymers to multifunctional mixed‐matrix membranes and powder composites. The materials exhibit visible/NIR emission and matrix‐based conductivity even as black bodies.
