Gamma‐Glutamyl Cysteine Ligase Activity as a Proxy for Human T Cell Function and Drug‐Induced Immunosuppression

open access: yesAdvanced Science, EarlyView.
GLed, a reversible lanthanide‐based GSH sensor that enables real‐time, single‐cell measurement of Gamma–Glutamyl Cysteine Ligase (GCL) activity ‐whose role in human T cells remains unclear‐ is developed. GLed directly links GCL activity to T cell effector functions and reveals its modulation by immunosuppressive drugs, identifying GCL as a critical ...

Microwave‐Assisted Synthesis of Cu/Co‐Based Nanoheterostructures for High‐Efficiency Alcohol Oxidation

open access: yesAdvanced Science, EarlyView.
Cu/Co‐based core‐shell nanocrystals (NCs) enable efficient hybrid water splitting via methanol and ethanol oxidation (MOR and EOR), outperforming traditional oxygen evolution reaction (OER). Synthesized via a one‐pot microwave process, the NCs evolve into oxide clusters that deliver high electrocatalytic activity and stability, enabling effective ...

Pulsed Laser Synthesis of Carbon Nanostructures from Organic Molecular Liquids: Structure, Kinetics and Photophysical Properties

open access: yesAdvanced Science, EarlyView.
The non‐focused nanosecond pulsed laser irradiation of aromatic liquids produces amorphous carbon nanodots (CNDs) or curved‐graphene quantum dots (c‐GQDs) by surface‐catalyzed 0‐order reactions under kinetic control. C hybridization partially changes from sp2 to sp3. O‐based groups passivate the surface.

On the Enhanced p‐Type Performance of Back‐Gated WS2 Devices

open access: yesAdvanced Electronic Materials, EarlyView.
A scalable method for directly growing WS2 enables robust and persistent p‐type behavior in back‐gated FETs, independent of metal contacts, thickness, or ambient conditions. Electrical measurements reveal minimal Schottky barrier heights and stable thermionic transport, while first‐principles simulations suggest tungsten vacancies or WO3 species as the
