Ultrasonic Vibration Assisted Laser Processing: A Hybrid Paradigm for Extreme Surface Enhancement
Rare Metals, Volume 45, Issue 10, October 2026.ABSTRACT Traditional laser processing techniques offer many advantages, but they often encounter limitations such as heat‐affected zones, recast layers, residual tensile stresses, and poor surface finish. The integration of ultrasonic vibration (UV) presents a promising hybrid approach to overcome these challenges by introducing beneficial effects like

A Quantum Degenerate Mixture of $^{87}$Rb and $^{133}$Cs [PDF]
, 2011 This thesis reports the formation of a dual-species Bose-Einstein condensate of $^{87}$Rb and $^{133}$Cs in the same trapping potential. Quantum degenerate mixtures exhibit rich physics inaccessible to single species experiments and provide an ideal ...

Small, Volume 22, Issue 55, 1 October 2026.Force‐driven microneedles are presented as active therapeutic microdevices that overcome the diffusion limits of conventional patches. By integrating gas generation, magnetic actuation, cavitation, or iontophoresis, these systems drive payloads deeper into tissue, enabling faster, more controlled delivery and highlighting key design principles and ...

Excited state spatial distributions in a cold strontium gas [PDF]
, 2012 This thesis describes the development of a new technique for measuring the spatial distribution of Rydberg atoms in a cold strontium gas. Strontium atoms are cooled and trapped in a magneto-optical trap and coherently excited to Rydberg states in a two ...

Efficient associative ionization of ultracold lithium and the long-lived Li_{2}^{+}
Physical Review ResearchWe report on the efficient production of Li_{2}^{+} ions in a magneto-optical trap (MOT) of Li atoms prepared in an ensemble of 2S, 2P, and 3S states. A linear Paul trap surrounding the MOT is used to trap and investigate the time evolution of the ion ...
