Molecules, ices and astronomy
1.25 Over the past 40 years, about 140 distinct molecular species have been detected in a wide range of astronomical locations (see http://www.cv.nrao.edu/~awootten/ allmols.html). We now know that molecules are present within our galaxy in the atmospheres of cool stars, in stellar envelopes, in planetary nebulae, in the ejecta of novae and supernovae, in diffuse and dense clouds in the interst...
متن کاملThe source of HLA molecules on platelets: Does platelets adsorb soluble HLA molecules from their environment?
Background: The origin and function of human leukocyte antigen (HLA) class I molecules on platelets are still highly arguable. Given the differences in the results of the previous studies in this regard, the lack of research in recent years, and the clinical importance of HLA class I molecules, the absorption capacity of platelets for soluble HLA class I molecules was studied in this investigat...
متن کاملSecond Virial Coefficients for Nonspherical Molecules and Their Experimental Measurements
The virial coefficients can be obtained from statistical mechanics in connection with the intermolecular potentials. The intermolecular potential of polyatomic molecules is usually assumed to consist of a spherically symmetric component plus a contribution due to asphericaity of the molecular charge distribution. In this study, the second virial coefficients have been calculated for N2...
متن کاملPutting molecules in their place.
Each class of microscope is limited to imaging specific aspects of cell structure and/or molecular organization. However, imaging the specimen by complementary microscopes and correlating the data can overcome this limitation. Whilst not a new approach, the field of correlative imaging is currently benefitting from the emergence of new microscope techniques. Here we describe the correlation of ...
متن کاملSuperconducting THz Detectors and Their Applications in Radio Astronomy
It is common knowledge now that the THz region, loosely defined from 0.1 THz to 10 THz, is rich in scientific and technological opportunities. For example, THz astronomical observations may help answer key questions in the field of astronomy and cosmology. In fact, an entirely new class of galaxy, formed at a very early stage in the universe, has recently been discovered through THz observation...
