recommendations! Published in 2018 at "Journal of Quantitative Spectroscopy and Radiative Transfer"

DOI: 10.1016/j.jqsrt.2018.04.027

Abstract: Abstract Trapping a single aerosol particle allows detailed investigation of its fundamental properties over extended time periods without external interferences. Optical trapping has developed into a powerful tool to perform such single-particle studies. However, trapping… read more here.

DOI: 10.1021/acs.analchem.2c00130

Abstract: Effective and arbitrary manipulation of particles in liquid has attracted substantial interest. Acoustic tweezers, a new and promising tool, exhibit high biocompatibility, universality, and precision but lack arbitrariness. In this work, we report a gigahertz… read more here.

DOI: 10.1021/acs.analchem.2c04043

Abstract: The refractive index points to the interplay between light and objects, which is rarely studied down to micronano scale. Herein, we demonstrated a conventional bright-field imaging technique to determine the local refractive index of single… read more here.

DOI: 10.1021/acs.analchem.9b01819

Abstract: In the atmosphere, there are several different trajectories by which particles can nucleate ice, two of the major pathways are deposition and immersion freezing. Single particle depositional freezing has been widely studied with spectroscopic methods… read more here.

DOI: 10.1073/pnas.2411414122

Abstract: Significance Concentrated particle suspensions are ubiquitous materials in industrial processes and natural phenomena. Often they exhibit a viscosity divergence at high shear, known as discontinuous shear thickening (DST). The origin of DST can be traced… read more here.
