Heme/NADH Mimics Co‐Decorated Allosteric Capsules for Regulating Oxygen Activation and Upregulating Intracellular Methionine Depletion

open access: yesAdvanced Science, EarlyView.
Through modifying the switchable µ‐oxo bridged FeIII‐porphyrins moiety and NADH mimics into a metal‐organic capsule, multiple responsive manners for O2 activation, chemical oxygenation and metabolic transformation have been demonstrated for upregulating intracellular methionine depletion and accumulation of methionine sulfoxide to achieve effective ...

Engineering Separated Dual O2 Reduction Cores into One Polymer Framework for Boosting Hydrogen Peroxide Production

open access: yesAdvanced Science, EarlyView.
Here the rational design of two O2 reduction cores into one polymer framework is showcased for synergistically facilitating H2O2 production via the “selfmarketing & cooperation” strategy. Photoactive units of pyrrolo[3,2‐b]pyrrole and porphyrin are successfully settled in covalent organic polymers (COPs) through polycyclizations of the relevant ...

Hybrid Plasmonic Nanorods/VO2 Photodetectors Sensitive to Short‐Wave Infrared Photons with Fast Response

open access: yesAdvanced Electronic Materials, EarlyView.
Together with the low external DC bias required (0.5V) and the fast response speed (trise down to 14 ms), the present hybrid plasmonic‐VO2 thin film photodetectors suggest a viable approach toward the development of effective photodetection in the SWIR spectrum.

Highly Active IrRuOx/MnOx Electrocatalysts with Ultralow Anode PGM Demand in Proton Exchange Membrane Electrolyzers

open access: yesAdvanced Energy Materials, EarlyView.
MnOx‐supported IrRuOx exhibits outstanding OER performance in both liquid electrolytes and real cell environments. The MnOx not only enhances the dispersion of IrRuOx but also induces a compressive strain effect. The incorporation of Ru leads to surface reconstruction.

Batch Extractive Distillation with Light Entrainer [PDF]

open access: yes, 2006
Use of a light entrainer in batch extractive distillation is justified when the mixture boils at a high temperature, or when an appropriate heavy or intermediate entrainer cannot be found.

A history of gastrectomy is a risk factor for choledocholithiasis in patients undergoing cholecystectomy: A single center retrospective study

open access: yesAnnals of Gastroenterological Surgery, EarlyView.
This retrospective study suggests that gastrectomy is a risk factor for choledocholithiasis. Especially in terms of the differences in reconstruction methods, the median time from gastrectomy to development of choledocholithiasis was 5.5 years for Roux‐en‐Y, which was significantly faster than 20 years for Billroth I and 35 years for Billroth II ...
