Rethinking ethanol separation in continuous spirit production from a process intensification perspective

Journal of Chemical Technology &Biotechnology, EarlyView.
Abstract Continuous neutral‐alcohol and food‐grade ethanol production is an energy‐intensive process in which distillation and rectification alone account for 50–85% of total plant energy use. While significant advances in separation technology have emerged over the past two decades, the spirits industry continues to rely predominantly on multi‐effect ...

Thiolate Salt Mediated Dynamic Silyl Ether Exchanges for Polymer Network Design and Deconstruction

Macromolecular Rapid Communications, EarlyView.
This work introduces thiolate salts as mediators for dynamic silyl ether exchange. This platform enables the synthesis of reprocessable covalent adaptable polymer networks (CANs) and allows for sterically controlled, and tunable deconstruction of silyl ether‐containing thermosets.

Carbonized polymer dots with aqueous‐stable room‐temperature phosphorescence: Mechanism, matrix engineering, and application

Responsive Materials, EarlyView.
This review focuses on inorganic and organic matrices that enable aqueous‐stable room‐temperature phosphorescence (RTP) in carbonized polymer dots (CPDs). It explains the underlying RTP mechanisms, highlights how matrix engineering provides spatial confinement and bonding interactions to stabilize triplet excitons in water, and demonstrates key ...

Layered Nickel–HHTP Networks for Efficient Chemiresistive Sensing of CH4 and CO2

Small, EarlyView.
First single‐crystal structure of Ni‐HHTP reveals alternating radical‐rich and closed‐shell layers forming a periodic, sandwich‐like framework. Coordinated and lattice water modulate interlayer spacing. The defined structure enables correlation between architecture and chemiresistive sensing toward CO2 and CH4, supported by theoretical insight into ...

Oxaziridines: Versatile Reagents in Modern Organic Synthesis

The Chemical Record, EarlyView.
Being capable of transferring an O atom and N‐group/atom, oxaziridines are considered multitasking agents. These are employed for diverse organic transformations, such as epoxidation of olefins, α‐ and γ‐hydroxylation/amination of carbonyl compounds, oxidation of sulfides, [3+2]cycloaddition with unsaturated systems.
