Atomic Tuning of Metal‐Support Interactions for Pathway‐Selective CO2 Photoreduction on TiO2

open access: yesAdvanced Science, EarlyView.
Single‐atom Fe and Cu catalysts anchored on TiO2 steer photocatalytic CO2 reduction toward distinct pathways. Fe sites favor rapid *CO desorption and selective CO formation, whereas Cu sites stabilize *CHO intermediates, enabling deep reduction and C─C coupling. Combined spectroscopy and DFT calculations reveal how metal–support interactions and oxygen

Compensatory Interplay Between Clarin‐1 and Clarin‐2 Deafness‐Associated Proteins Governs Phenotypic Variability in Hearing

open access: yesAdvanced Science, EarlyView.
Functional compensation between clarin‐1 and clarin‐2 in cochlear hair cells. Hearing loss associated with CLRN1 mutations shows striking phenotypic variability; however, the underlying mechanisms remain poorly understood. This study reveals that clarin‐1 and clarin‐2 function cooperatively in cochlear hair cells to sustain mechanoelectrical ...

An analysis of turbulent diffusion flame in axisymmetric jet [PDF]

open access: yes
The kinetic theory of turbulent flow was employed to study the mixing limited combustion of hydrogen in axisymmetric jets. The integro-differential equations in two spatial and three velocity coordinates describing the combustion were reduced to a set of

Ultraviolet Photodetectors Based on 4H‐SiC With Honeycomb‐Like Light‐Trapping Structures

open access: yesAdvanced Science, EarlyView.
A facile photoelectrochemical etching method creates honeycomb‐like light‐trapping microstructures on SiC. These microstructures suppress UV reflection and enhance absorption by extending the optical path and facilitating multiple internal reflections, while strengthening the local electric field.

In Situ Electrochemical Activation of Pseudo‐Layered NbS3 via Interlayer Expansion and Dual Redox for High Mg‐Ion Storage

open access: yesAdvanced Science, EarlyView.
A quasi‐1D pseudo‐layered NbS3 cathode for magnesium‐ion batteries can be created through electrochemically induced interlayer expansion. The widened ion‐transport channels enable fast magnesium ion diffusion and unlock coupled cationic‐anionic redox chemistry.

Effect of Air Quantity Distribution Ratio on Flame Height of Flue Gas Self-Circulation Burner

open access: yesJournal of Applied Fluid Mechanics, 2020
It is a difficult scientific problem of applied fluid mechanics that the flame is too long and does not match the furnace chamber in a small restricted heating space. This paper aims to investigate the effect of the air quantity distribution ratio on the

Dynamic Supramolecular Polyurethane Elastomers Enabling Bioinspired Strain‐Adaptive Stiffening to Resolve the Softness–Strength Paradox

open access: yesAdvanced Science, EarlyView.
Segmental‐level molecular engineering of a supramolecular polyurethane elastomer integrates strain‐adaptive chains, soft elastic segments, and dynamic hydrogen bonding motifs. This design reconciles skin‐like softness with muscle‐level strength, offering a sustainable and high‐performance material platform for next‐generation artificial skin and soft ...
