Sulfur source-mediated transcriptional regulation of the rhlABC genes involved in biosurfactants production by Pseudomonas sp. strain AK6U

open access: yesFrontiers in Microbiology, 2014
Despite the nutritional significance of sulfur, its influence on biosurfactants production has not been sufficiently studied. We investigated the expression of key biosurfactants production genes, rhlABC, in cultures of Pseudomonas sp.

Unveiling the Electrolyte and Solid Electrolyte Interphase in Sodium Ion Batteries: Mechanisms, Progress, and Perspectives

open access: yesAdvanced Materials, EarlyView.
This review summarizes the recent advances in sodium‐ion battery electrolytes (including organic, aqueous, gel, ionic liquid, and solid‐state types) and their influence on the solid electrolyte interphase (SEI). It discusses SEI formation, aging, and optimization, as well as cases where no SEI forms, providing insights into the critical relationship ...

Revealing the Neglected Role of Passivation Layers of Current Collectors for Solid‐State Anode‐Free Batteries

open access: yesAdvanced Materials, EarlyView.
An in situ X‐ray absorption spectroscopy experiment revealed that the surface passivation layers on copper and stainless steel interact with the sulfide‐based solid‐state electrolyte upon contact, leading to the formation of various interfacial species.

Fast and Reversible Red Emission Modulation in Photoswitchable Molecules Toward Optical Data Storage

open access: yesAdvanced Optical Materials, EarlyView.
A series of intense red‐emitting BTCPO4 photoswitches is synthesized, and their photophysical properties, such as fluorescence quantum yield, fatigue resistance, and reversible cyclization, are reported. The issue of slow reverse cyclization, which hinders fluorescence modulation (ON‐OFF) of these molecules, is overcome by utilizing energy transfer to ...

The Influence of Interfacial Chemistry on Magnesium Electrodeposition in Non-nucleophilic Electrolytes Using Sulfone-Ether Mixtures

open access: yesFrontiers in Chemistry, 2019
One of the limiting factors in the development of magnesium batteries is the reversibility of magnesium electrodeposition and dissolution at the anode. Often irreversibility is related to impurities and decomposition.

Recent Progress in Strategies to Enhance the Spin‐Orbit Coupling of Multiresonance Thermally Activated Delayed Fluorescent Materials for Narrowband Organic Light‐Emitting Diodes

open access: yesAdvanced Photonics Research, EarlyView.
For multiresonance thermally activated delayed fluorescent emitters, the reverse intersystem crossing (RISC) process is of paramount importance. This review summarizes two approaches to enhance the RISC rate by improving spin‐orbit coupling: the heavy atom strategy and the long‐range charge‐transfer/short‐range charge‐transfer strategy.

Bis(3-nitrophenyl) sulfone

open access: yesActa Crystallographica Section E, 2008
The asymmetric unit of the title compound, C12H8N2O6S, an important diphenyl sulfone derivative, contains one half-molecule; a mirror plane passes through the SO2 group. The dihedral angle between the two symmetry-related benzene rings is 40.10 (13)

Light Mediated Sulfonylation/C–H Activation/Annulation of Benzimidazoles Derivatives Catalyzed by Diarylmethylium Tetrafluoroborate Salts: An Experimental and Computational Study

open access: yesAdvanced Synthesis &Catalysis, EarlyView.
Through the exploiting of visible‐light, a key photoactive complex, and an acid‐catalyzed proton‐coupled electron transfer, polycyclic sulfonylated benzimidazoles are obtained through a domino process including sulfonylation, C–H activation, and annulation. Diarylmethylium tetrafluoroborates are employed as inexpensive organocatalyst capable of forming

Fe‐Photocatalyzed Decarboxylative Giese‐Type Reaction of α‐N, O or S Carboxylic Acids: Insight into the Mechanism of the Radical Formation

open access: yesAdvanced Synthesis &Catalysis, EarlyView.
Electron‐deficient alkenes can be functionalized with α‐amino, α‐alkoxy and α‐alkylthio radicals formed by Fe‐photocatalyzed decarboxylation of the corresponding carboxylic acids. The reactions proceed under smooth ligandless conditions with inexpensive base and in the absence of oxidant. A mechanistic computational TD‐DFT study supports the occurrence
