Creatine-mediated ferroptosis inhibition is involved in the intestinal radioprotection of daytime-restricted feeding

open access: yesGut Microbes
Ionizing radiation-induced intestinal injury (IRIII) is a catastrophic disease lack of sufficient medical countermeasures currently. Regulation of the gut microbiota through dietary adjustments is a potential strategy to mitigate IRIII.

In Situ Utilization of Co‐Existing Metal Ions to Fabricate Single‐Atom Catalyst for Boosting Fenton‐Like Activity

open access: yesAdvanced Science, EarlyView.
A metal‐free TQBQ‐COF with pre‐designed anchoring sites captures coexisting Cu²⁺ from wastewater to form a single‐atom catalyst within 1 min. This in‐situ fabrication boosts visible‐light photo‐Fenton activity, enabling efficient removal of organics pollutants via 1O2 and holes.

Sustained and Efficient Ethanol Oxidation by Tethering Tunable N‐Donors Onto Integrated MXene/Pd‐Electrodes

open access: yesAdvanced Science, EarlyView.
Three novel 3D layered integrated electrodes for Pd‐catalysed ethanol oxidation are developed; their innovative design features N‐heterocyclic amide linkers grafted on an MXene, co‐anchoring Pd nanoparticles via “hand‐in‐hand” coordination. The resulting well‐defined Pd (111) catalytic sites help achieve extremely stable long‐term cycling with ...

ZIF‐67‐Confined Pd Single‐Atom Catalysts Implanted Into Polydopamine‐Modified Bamboo Microchannels for Robust Continuous‐Flow Hydrogenation

open access: yesAdvanced Science, EarlyView.
The report presents a facile room‐temperature method to stabilize Pd single‐atom catalysts within ZIF‐67 crystals during their formation. Despite an ultralow Pd loading (0.0014 wt%), the catalytic microreactor, featuring atomically dispersed Pd‐N4 sites in ZIF‐67, demonstrates superior robustness and maximized Pd utilization, significantly ...

Risk factor analysis and development of nomogram prediction model for central venous catheter-related thrombosis in burn patients: a retrospective observational study

open access: yesThrombosis Journal
Background Central venous catheter (CVC)-related thrombosis (CRT) has become a common iatrogenic complication in burn patients. Early and precise prediction is the foundations of effective prevention of CRT. However, there is not specific tool to predict

Selective and Long‐Term Stable Ammonia Electrolysis Using Pt–WOx Catalysts with Suppressed NOx Formation and Enhanced Activity

open access: yesAdvanced Science, EarlyView.
This study reports photodeposited Pt nanoparticles on WOx nanowires (Pt–WOx (P)) as a bifunctional catalyst for ammonia electrolysis. Strong metal–support interactions promote electron transfer to Pt, lowering the energy barrier of the rate‐determining step and suppressing NOx formation.

Establishment and evaluation of a novel rat model of the fourth ventricle hemorrhage

open access: yesAnimal Models and Experimental Medicine
Background Hemorrhagic expansion into the fourth ventricle is an independent risk factor for poor outcomes in intraventricular hemorrhage (IVH) patients. However, to date, available animal models of IVH are limited to models of supratentorial ventricular
