Enhanced Activity for CO Oxidation over WO<sub>3</sub> Nanolamella Supported Pt Catalyst
WO<sub>3</sub> nanolamella supported Pt catalyst has been prepared
and applied for CO oxidation in this work. A significantly enhanced
activity has been achieved, compared to that of the Pt catalyst supported
by the WO<sub>3</sub> nanoparticle. The catalyst characterization
using X-ray diffraction (XRD), scanning electronic microscopy (SEM),
high-resolution transmission electron microscopy (HRTEM), and N<sub>2</sub> adsorptionâdesorption confirms that the WO<sub>3</sub> nanolamella supported Pt catalyst possesses higher Pt dispersion,
improved metalâsupport interaction with a higher electron density
of Pt, and a weak adsorption of CO, leading to the significantly enhanced
activity for CO oxidation

Automatically Aligned and Environment-Friendly Twisted Stacking Terahertz Chiral Metasurface with Giant Circular Dichroism for Rapid Biosensing
Chiral metasurfaces are capable of generating a huge
superchiral
field, which has great potential in optoelectronics and biosensing.
However, the conventional fabrication process suffers greatly from
time consumption, high cost, and difficult multilayer alignment, which
hinder its commercial application. Herein, we propose a twisted stacking
carbon-based terahertz (THz) chiral metasurface (TCM) based on laser-induced
graphene (LIG) technology. By repeating a two-step process of sticking
a polyimide film, followed by laser direct writing, the two layers
of the TCM are aligned automatically in the fabrication. Laser manufacturing
also brings such high processing speed that a TCM with a size of 15
Ă 15 mm can be prepared in 60 s. In addition, due to the greater
dissipation of LIG than that of metals in the THz band, a giant circular
dichroism (CD) of +99.5 to â99.6% is experimentally realized.
The THz biosensing of bovine serum albumin enhanced by the proposed
TCMs is then demonstrated. A wide sensing range (0.5â50 mg
mLâ1) and a good sensitivity [ÎCD: 2.09% (mg
mLâ1)â1, Îf: 0.0034 THz (mg mLâ1)â1] are
proved. This LIG-based TCM provides an environment-friendly platform
for chiral research and has great application potential in rapid and
low-cost commercial biosensing

Porous MS<sub>2</sub>/MO<sub>2</sub> (M = W, Mo) Nanorods as Efficient Hydrogen Evolution Reaction Catalysts
Highly
efficient and stable electrochemical catalysts of porous
one-dimensional (1D) MS<sub>2</sub>/MO<sub>2</sub> (M = W, Mo) nanorods
have been developed for the hydrogen evolution reaction (HER). The
materials are synthesized via a âlow-temperature conversionâ
method. The as-prepared catalysts exhibit numerous advantages: abundant
amount of exposed MS<sub>2</sub> edges, high conductivity, and enhanced
mass transport. The MS<sub>2</sub>/MO<sub>2</sub> nanorods show efficient
