Detection of bioaerosols, or primary biological aerosol particles (PBAPs), has become
increasingly important for a wide variety of research communities and scientific questions. In …

Trap** a single aerosol particle allows detailed investigation of its fundamental properties
over extended time periods without external interferences. Optical trap** has developed …

MXenes, a large family of two-dimensional materials that are intensely investigated for a
broad range of applications, are unstable in water, spontaneously forming TiO2. Several …

The development of a micromotor with unique spiky morphology based on sporopollenin
exine capsules (SECs) is reported here. A widely abundant natural material extracted from …

The attribution of single particle sources of atmospheric aerosols is an essential problem in
the study of air pollution. However, it is still difficult to qualitatively analyze the source of a …

Understanding airborne survival and decay of microorganisms is important for a range of
public health and biodefense applications, including epidemiological and risk analysis …

Weak interaction between flocculants and antibiotics is a limitation in the flocculation of
combined contaminants of heavy metals and antibiotics. To solve this problem, a novel …

Atmospheric particles experience various physical and chemical processes and change
their properties during their lifetime. Most studies on atmospheric particles, both in laboratory …

From the early optical-tweezers approach, which uses a single tightly focused laser beam to
levitate dielectric or absorbing micron-sized particles, to the recently developed optical traps …

In 1832 Hamilton predicted that a collimated light beam propagating through a biaxial crystal
parallel to one of its optical axes refracts as a slanted cone within the crystal and emerges as …
