This article focuses on the effect of particle size on the additive manufacturing process.

The BeNano 180 Zeta Pro is the latest zeta potential and particle size analyzer from Bettersize Instruments. The 180 can perform DLS, ELS, and SLS, rendering it a highly accurate and versatile machine.

In a new study, exhaled aerosols were compared between infected SARS-CoV-2 patients and healthy controls for the first time. A preprint version of this study, which is yet to undergo peer review, is available on the medRxiv* server.

Based on the particle size evolution of tectonic coal in formation process, the differences between tectonic coal and intact coal in pore structure and initial gas desorption characteristics were studied. Then, the influences of particle size reduction on pore structure and initial gas desorption characteristics were investigated; and the initial gas energy release model was derived, which was used to calculate the gas expansion energy of tectonic coals with different particle sizes. This study concludes that the particle size of tectonic coal will be reduced under the pulverization effect dur...
