TL;DR: N nanometer-sized pH probes were dispersed in droplets to report pH via surface-enhanced Raman spectroscopy, and found that the pH in the core of a droplet is higher than that of bulk solution by up to 3.6 pH units, suggesting the accumulation of protons at the air/water interface.

TL;DR: A three-layer mask consisting of outer layers of a flexible, tightly woven fabric and an inner layer consisting of a material designed to filter out particles is recommended, which should produce an overall efficiency of >70% at the most penetrating particle size and >90% for particles 1 m and larger if the mask fits well.

TL;DR: In this article, the first room temperature seed-mediated synthesis of gold nanoparticles (AuNPs) in the presence of citrate and a gold salt was reported, and the authors investigated the AuNP growth mechanism via time resolved UV-vis spectroscopy, dynamic light scattering, and transmission electron microscopy.

TL;DR: The results indicate the broad applicability of this gold nanoparticle/bacterial cellulose nanocomposites for analyte detection and its use under low and high pH conditions.

TL;DR: The objective of this work was to characterize the aerosol emissions from the operation of a fuse-deposition modeling 3D printer, and suggests that aerosols are not a result of volatilization and subsequent nucleation of ABS or direct release of ABS aerosols.
