Advanced Engineering Materials, EarlyView.This study explores aerosol jet‐printed (AJP) surface roughness, its effects on the performance of microwave electronics, and its process contributors. First, an electromagnetic model is vetted for AJP's unique roughness signature. Simulations are built which show process‐induced roughness is as significant as conductor resistivity in driving microwave

Polarized laser-wakefield-accelerated kiloampere electron beams
, 2019 High-flux polarized particle beams are of critical importance for the investigation of spin-dependent processes, such as in searches of physics beyond the Standard Model, as well as for scrutinizing the structure of solids and surfaces in material ...

Selective C−C Coupling by Spatially Confined Dimeric Metal Centers
iScience, 2020 Summary: Direct conversion of carbon dioxide (CO2) to high-energy fuels and high-value chemicals is a fascinating sustainable strategy. For most of the current electrocatalysts for CO2 reduction, however, multi-carbon products are inhibited by large ...

Advanced Engineering Materials, EarlyView.Morphological features of three defect types in metal additive manufacturing (AM)—lack of fusion, keyhole, and gas‐entrapped pores—are statistically characterized using best‐fit distributions evaluated via coefficient‐of‐determination, Kolmogorov–Smirnov test, and quantile–quantile plots.

Scintillation reduction for combined Gaussian-vortex beam propagating through turbulent atmosphere
, 2011 We numerically examine the spatial evolution of the structure of coherent and partially coherent laser beams (PCBs), including the optical vortices, propagating in turbulent atmospheres.

Eos, Transactions American Geophysical Union, 1983 There is a growing, interdisciplinary field of research which I prefer to call lidar meteorology. It involves the probing of the atmosphere with laser beams to measure the various physical parameters of concern to atmospheric scientists. When this is done with a high‐energy, pulsed laser, that is, with a lidar system, the atmosphere can be monitored at

Advanced Engineering Materials, EarlyView.This study presents rapid evaluation methods for scan strategies in powder bed fusion (PBF) of polymers with a NIR laser as an example for its application. It uses line buffer‐based calculations and point density fields to predict the performance of four different scan strategies. The methods show promising results in laser‐based PBF of polymer samples,
