Transient Laser‐Shocked Synthesis of Amorphous Layer‐Supported Metal Nanocrystals for Efficient Nitrate Reduction

Advanced Materials, EarlyView.
A general, versatile laser‐shock synthesis process is reported to produce various bimetallic CuNi, CuFe, CuCo, and medium‐entropy CuFeCoNi heterostructures, in which crystalline metal nanoparticles are anchored to amorphous hydroxide supports. During nitrate reduction reaction, the heterostructures undergo dynamic amorphous/crystalline reconstruction ...

Anisotropic beam spreading in uniaxial crystals

Optics Communications, 2004
The anisotropic spreading of a paraxial beam propagating orthogonally to the optical axis inside a uniaxial crystal is investigated. The lack of rotational invariance around the propagation direction suggests to consider the mean square width (MSW) of the beam in any transverse direction, which turn out to be a quadratic form of the unit vector ...

Beam-width spreading of vortex beams in free space

2017 International Conference on Optical Instruments and Technology: Optoelectronic Devices and Optical Signal Processing, 2018
Based on the extended Huygens-Fresnel principle and the definition of second-order moments of the Wigner distribution function, the analytical expression for the beam-width spreading of Gaussian Schell-model (GSM) vortex beams in free space are derived, and used to study the influence of beam parameters on the beam-width spreading of GSM vortex beams ...
