Laser Ultrafast Confined Alloying of Sub‐5 nm RuM (M = Cu, Rh, and Pd) Particles on Carbon Nanotubes for Hydrogen Evolution Reaction

open access: yesAdvanced Science, EarlyView.
In this work, the synthesis of carbon nanotubes (CNTs) supported sub‐5 nm dominant intermetallic RuCu, RuRh, and RuPd NPs are succeeded by the proposed method of nanosecond laser ultrafast confined alloying (LUCA), which is featured by its unique ultrafast heating and cooling rates and high stability for long‐term alkaline HER catalysis application ...

Novel Gas Sensor Signal Acquisition Method: Amplifying Sensor Signals and Enabling Efficient Gas Identification

open access: yesAdvanced Science, EarlyView.
This study presents a novel method to improve sensitivity and gas identification in resistive gas sensors by dividing operation into reaction and signal detection phases. The reaction phase optimizes chemisorption, while the signal detection phase, using a read‐bias technique, enhances sensitivity.

Minimizing Energy Demand in the Conversion of Levulinic Acid to γ‑Valerolactone via Photothermal Catalysis Using Raney Ni

open access: yesAdvanced Science, EarlyView.
Upgrading lignocellulosic wastes into value‐added compounds represents an excellent option to reduce the current overreliance on fossil fuels. γ‐Valerolactone is especially attractive for its multiple applications such as biofuel or green solvent.
