Unassisted Switchable Dual‐Photoelectrode Devices Utilizing p‐n Carbon Quantum Dots as “Semiconductor Electrolytes”: Optimization Between H2O2 and Solar Electricity Production

open access: yesAdvanced Science, EarlyView.
p‐n type carbon quantum dots (N‐CQDs) are designed as a conceptually‐new “semiconductor electrolyte” to develop a self‐driven photoelectrochemical cell that can be switched to optimize between H2O2 production and electricity generation under visible‐light illumination with water and O2 as reaction reagents.

Boosting Organic Long Persistent Luminescence by Enhancing Charge Separation Processes in Three‐Component Systems

open access: yesAdvanced Science, EarlyView.
Electron donor TMB is introduced into BF2bdk‐PhB system to enhance charge separation process. The resultant three‐component materials exhibit visible‐light‐excitable OLPL afterglow lasting for several hours under ambient environment, with OLPL efficiency of ≈10% and display OLPL brightness comparable to inorganic materials.

Human Schlafen 14 Cleavage of Short Double‐Stranded RNAs Underpins its Antiviral Activity

open access: yesAdvanced Science, EarlyView.
SLFN14 is associated with human diseases. SLFN14 is found to cleave RNAs containing short duplexes. The cryo‐EM structures of SLFN14 and SLFN14‐hairpin RNA complex reveal that SLFN14 assembles into a ring‐like dimer; two RNase domains form an RNA‐binding groove accommodating a hairpin RNA.

Electronic Microenvironment Regulation of Bismuth‐salophen Single‐site Catalysts for Enhanced Selectivity in CO2 Electrolysis to Formic Acid

open access: yesAdvanced Science, EarlyView.
The microenvironment modulation of Bi SSCs via electronegative group (─F/─H/─OMe) modification demonstrably suppresses the HER at high current densities, achieving a HCOOH FE of 95%. The ─F group optimizes the electronic structure of Bi, significantly enhancing CO2 adsorption and reducing the energy barrier for *OCHO intermediate formation, thereby ...

Imprinting Electrically Switchable Scalar Spin Chirality by Anisotropic Strain in a Kagome Antiferromagnet

open access: yesAdvanced Science, EarlyView.
It is shown that anisotropic strain offers a novel approach to control the magnetic ground state in heterostructures of a Kagome antiferromagnet, unlocking new functionalities. This strain induces finite scalar spin chirality, resulting in a pronounced Berry curvature in momentum space, leading to room‐temperature anomalous Hall effect.

Near Room‐Temperature Ferromagnetic Phase Achieved in 4d Ruthenate via Interfacial Ferrimagnetic Coupling and Octahedral Rotation Engineering

open access: yesAdvanced Science, EarlyView.
Transition metal oxides combining strong spin‐orbit coupling, near‐room‐temperature ferromagnetism, and high conductivity are rare. A Ca0.5Sr0.5RuO3 interfacial phase between LaMnO3 layers has all these features, high Tc, enhanced magnetization, and reduced coercivity.

Loss of STARD7 Triggers Metabolic Reprogramming and Cell Cycle Arrest in Breast Cancer

open access: yesAdvanced Science, EarlyView.
Breast cancer cells undergo metabolic and transcriptomic reprogramming to support aberrant cell proliferation. Their mitochondria rely on the transfer of phosphatidylcholine from the endoplasmic reticulum to their membranes by STARD7, a candidate upregulated in breast cancer, to be functional.

Ecofriendly Upcycling of Poly(vinyl chloride) Waste Plastics into Precious Metal Adsorbents

open access: yesAdvanced Science, EarlyView.
Poly(vinyl chloride) waste plastics are simply transformed into high‐performance precious metal (PM) adsorbents via a facile and green hydrazine‐functionalization process. The resultant adsorbent effectively and selectively recovers PM from real‐world leachates via its combined chemisorption and reduction mechanisms.

Advanced Atomic Layer Modulation Based Highly Homogeneous PtRu Precious Metals Alloy Thin Films

open access: yesAdvanced Science, EarlyView.
A unique idea of atomic layer modulation (ALM) that sequentially pulses DDAP and Ru(TMM)(CO)3, two precursors with one counter reactant O2 to produce ALM‐PtRu homogeneous PtRu bimetallic alloys at the nanoscale. It smartly adjusted precursor pulse time and temperature, ensuring stoichiometric and compositionally atomistic controlled highly ...

Nanoscale Metal‐Organic Framework‐Based Self‐Monitoring Oxygen Economizer and ROS Amplifier for Enhanced Radiotherapy‐Radiodynamic Therapy

open access: yesAdvanced Science, EarlyView.
A Fe (III)–Pt (II) porphyrin framework‐based radiosensitizer (FPTM‐LP) is constructed to serve as an oxygen economizer, hypoxia self‐monitoring device, and reactive oxygen species (ROS) amplifier. The glutathione (GSH)/pH‐responsive release of lonidamine achieves oxygen‐economization to combat hypoxia‐induced radioresistance guided by near infrared ...
