Theory and simulation of spectral line broadening by exoplanetary atmospheric haze

, 2018
Atmospheric haze is the leading candidate for the flattening of expolanetary spectra, as it's also an important source of opacity in the atmospheres of solar system planets, satellites, and comets.

Stabilization of Bio-Oss® particulates using photocurable hydrogel to enhance bone regeneration by regulating macrophage polarization

Frontiers in Bioengineering and Biotechnology, 2023
Bone substitutes are widely used in maxillofacial and oral surgeries. However, in clinical practice, bone substitutes with various forms, including separated particulates, powders, and blocks, have exhibited poor handling properties and space maintenance

Apparatus for sampling particulates in gases [PDF]

, 1973
A device for sampling particulates in gases is described. The device is used to obtain samples of the upper atmosphere. The equipment used a common source of gas pressure to provide the driving gas of an air ejector pump.

Instillation of Particulate Suspensions to the Lungs

Bio-Protocol, 2017
Inhaled fine particulates are thought to cause chronic pulmonary inflammation through the deposition of particulates into the lungs. To investigate the effect of fine particulates on the lungs, instillation of suspension of particulates into the lungs is

A Review of the Fire and Explosion Hazards of Particulates

, 2014
Particulate fires and explosions cause substantial loss of life and property. With the goal of understanding, preventing, or at least mitigating particulate fire and explosion hazards, we review basics.

The influence of physical and chemical linkage on the properties of nanocomposites [PDF]

, 2005
It has been shown by several groups that the mechanical and electrical behavior of composites changes quite substantially, and often beneficially, when the filler particle size is less than 100 nm in diameter.

Eulerian simulation of the fluid dynamics of helicopter brownout [PDF]

, 2008
A computational model is presented that can be used to simulate the development of the dust cloud that can be entrained into the air when a helicopter is operated close to the ground in desert or dusty conditions.
