Microspheres made from highly transparent glass can perform as very high quality optical microcavities or optical microresonators. Ceramic microspheres are used primarily as grinding media. Hollow microspheres loaded with drug in their outer polymer shell were prepared by a novel emulsion solvent diffusion method and spray drying technique.
By heating up different elements so atoms evaporated and were then condensed in an inert argon atmosphere, fine particles of almost all the elemental solids were made and then analyzed using electron microscopes. The decahedral particles were found for all face centered cubic materials and a few others, often together with other shapes. [23 ...
Micromeritics is the science and technology of small particles pioneered by Joseph M. DallaValle. [1] It is thus the study of the fundamental and derived properties of individual as well as a collection of particles. The knowledge and control of the size of particles has importance in pharmacy and materials science.
Particulates or atmospheric particulate matter (see below for other names) are microscopic particles of solid or liquid matter suspended in the air.The term aerosol refers to the particulate/air mixture, as opposed to the particulate matter alone, [1] though it is sometimes defined as a subset of aerosol terminology. [2]
All everyday objects that can be touched are ultimately composed of atoms, which are made up of interacting subatomic particles, and in everyday as well as scientific usage, matter generally includes atoms and anything made up of them, and any particles (or combination of particles) that act as if they have both rest mass and volume.
The scientists theorize that these microbes are the descendants of life that thrived in the lake before its top became permanently frozen. In Jurassic Park, the Chaostician Ian Malcolm ...
Dust is made of fine particles of solid matter. [1] On Earth, it generally consists of particles in the atmosphere that come from various sources such as soil lifted by wind (an aeolian process), volcanic eruptions, and pollution. Dust in homes is composed of about 20–50% dead skin cells. [2]
Russia's Foreign Ministry on Saturday denounced new U.S. sanctions against Moscow's energy sector as an attempt to harm Russia's economy at the risk of destabilising global markets and said the ...
