Experimental studies on curling development of artificial soils

open access: yesJournal of Rock Mechanics and Geotechnical Engineering, 2019
Soil curling is an important phenomenon associated with volume changes induced by increasing soil suction upon desiccation. The study of soil behaviors associated with drying in soils (e.g.

Highly Selective Electroreduction of CO2 to CH4 on Cu–Pd Alloy Catalyst: the Role of Palladium‐Adsorbed Hydrogen Species and Blocking Effect

open access: yesAdvanced Science, EarlyView.
The blocking effect induced by the Pd atom would interrupt the C─C coupling reaction by increasing the intermolecular distance between adjacent *CO and *CHO intermediates adsorbed on the Cu atoms when introduced Pd into the Cu lattices and the *CO protonation effect of palladium‐adsorbed *H species boosts the CH4 formation on the Cu–Pd alloy catalyst ...

A Bias‐Tunable Multispectral Photodetector Based on a GaN/TexSe1‐x Homo‐Type Heterojunction with a Unidirectional Barrier

open access: yesAdvanced Science, Volume 12, Issue 17, May 8, 2025.
A bias‐tunable multispectral photodetector based on a TexSe1‐x/GaN homo‐type heterojunction with a unidirectional barrier is proposed. By modulating the bias polarity and magnitude, the device's spectral response range can be extended from UV to the SWIR region.

Sustainable High‐Performance Aqueous Batteries Enabled by Optimizing Electrolyte Composition

open access: yesAdvanced Science, EarlyView.
Lithium‐free aqueous batteries provide a safe, low‐cost alternative to lithium‐ion batteries for energy storage. This study introduces an optimized electrolyte using inexpensive salts, enhancing both energy density and cycling stability. The resulting battery delivers high power and efficiency, demonstrating strong potential for supercapacitor ...
