Orthogonal Quintuple‐Stimuli Responsiveness in an Ultrastable, Ultrabright Cu16 Nanocluster via Molecular and Supramolecular Engineering

Advanced Optical Materials, EarlyView.
Through simultaneous molecular and supramolecular engineering, an atomically precise nanocluster Cu16 with ambient ultrastability and ultrabright luminescence is constructed. Cu16 employs a dual structural/luminescent channel mechanism to achieve orthogonal responsiveness to five external stimuli, demonstrating multidimensional signalling capability ...

Molecular Electrocatalyst Enables Direct Electrochemical Capture and Conversion of CO2 up to Atmospheric Concentration

Angewandte Chemie, EarlyView.
A molecular manganese electrocatalyst enables the direct electrochemical capture and conversion of dilute CO2 (1% – 0.2%) to CO with nearly unit Faradaic efficiency, achieving high efficiency even at atmospheric concentrations (420 ppm). By bypassing energy‐intensive pre‐concentration steps, this integrated approach highlights a sustainable pathway for

Carbon dioxide capture from air in buildings – Design and techno-economic feasibility of practical systems

Journal of CO2 Utilization
Direct Air Capture (DAC) is needed alongside other CO2 removal methods to ensure that the total amount of CO2 required is removed from the atmosphere so that global warming can be limited to below 2 °. While large-scale DAC farms are a promising solution,

Tumbling Magnetic Microrobots for Targeted In Vivo Drug Delivery in the GI Tract

Advanced Robotics Research, EarlyView.
We introduce a microrobot design and integrated system for on‐demand targeted drug release in the gastrointestinal tract. The microrobot has an embedded magnet for actuation with external magnetic fields and is visualized in real time using ultrasound. It has two drug release ports sealed with a thermally sensitive wax. Local heating of the wax using a

Arylhydrazines: Convenient Homogeneous Reductants for Scalable Cross‐Coupling

Angewandte Chemie, EarlyView.
Reductive cross‐couplings enable efficient C–C bond formation but are limited by the heterogeneity of Zn or costly reagents like TDAE. We report arylhydrazines as inexpensive, convenient reductants for Ni‐catalyzed sp2–sp3 coupling of aryl halides and secondary alkyl iodides. Mechanistic studies support hydrazine‐mediated NiII reduction for a NiI/NiIII

An integrated solution to mitigate climate change through direct air capture and diabatic compressed air energy storage

Energy Conversion and Management: X
Direct air capture (DAC) is a technology designed to capture CO2 directly from ambient air for carbon removal, while compressed air energy storage (CAES) involves compressing and storing air for later use in energy generation.
