Abstract Measuring soil health indicators (SHIs), particularly soil total nitrogen (TN), is an important and challenging task that affects farmers’ decisions on timing, placement, and quantity of fertilizers applied in the farms. Most existing meth

Physics of Plasmas. 30
Kinetics of ion and neutral atom emission features were compared for nanosecond laser-produced plasmas generated from several metal targets (i.e., Al, Ti, Zr, Nb, Ta) and an alloy containing all of these as principal alloying elements. Plasmas were p

This study explores the adoption of laser-induced breakdown spectroscopy (LIBS) for the analysis of lateral-flow immunoassays (LFIAs). Gold (Au) nanoparticles are standard biomolecular labels among LFIAs, typically detected via colorimetric means. A

As cancer continues to be one of the world’s leading killers, efforts to replace expensive and invasive therapies that cause harmful side effects led to the exploration of cold atmospheric plasma (CAP) and electroporation (EP) as efficient and sele
This chapter provides a brief overview of the physics behind ultrafast laser-induced breakthrough spectrometry (LIBS) generation, emission, and plume fundamentals. A comparison between nanosecond LIBS and ultrafast LIBS is discussed wherever it is ap
