Radiometric Constraints on the Timing, Tempo, and Effects of Large Igneous Province Emplacement
Geophysical Monograph Series, Page 27-82., 2021 Exploring the links between Large Igneous Provinces and dramatic environmental impact
An emerging consensus suggests that Large Igneous Provinces (LIPs) and Silicic LIPs (SLIPs) are a significant driver of dramatic global environmental and biological changes, including mass extinctions.

The Effect of Blue and Infrared Laser Melting Frequency on Oxide Morphology in 304L [PDF]
arXivContinuous Wave Laser Beam (LB) melting offers control over the localized heating and cooling of melt pools for welding, brazing, additive manufacturing, and solidification. Research into laser-liquid metal interactions have primarily focused on the heat and mass transport under large thermal gradients imposed by the localized melting conditions ...
arxiv
Solidification type welding process experiments in conditions of microgravity were performed. The role of convection in such phenomena was examined and convective effects in the small volumes obtained in the laser weld zone were observed.

Correlative Characterizations Reveal the Structure‐Bonding‐Property Relationship at a Local Scale
Chemistry–Methods, EarlyView.Grain boundaries (GBs) modify the local microstructures, chemical bonding, and carrier transport of polycrystalline materials, influencing their overall mechanical and functional properties. We developed a correlative characterization method by combining several advanced ex‐situ and in‐situ techniques to reveal the relationship between structure ...

Plasma Production by Laser Ablation of Heavy Metals
Contributions to Plasma Physics, EarlyView.ABSTRACT An Nd:YAG focused laser operating at 1064 nm, 3 ns pulse width, 360 mJ pulse energy, is employed to irradiate heavy metals, such as Ta, W, Pt, Au, and Pb. The in‐vacuum irradiation produces an expanding plasma at the target surface which has high density, temperature, and kinetic energy of emitted ions. Ions have a velocity of the order of 104
