Chemical physics is a subdiscipline of chemistry and physics that investigates physicochemical phenomena using techniques from atomic and molecular physics. The term was first used by professor A. Eucken in 1930. The main branches of chemical physics are studies of electronic and molecular structure, spectral properties of chemical substances and dynamic behavior of chemical processes. The chai...

We have synthesized a graphene oxide (GO)-based theranostic nanodelivery system (GOTS) for magnetic resonance imaging (MRI) using naturally occurring protocatechuic acid (PA) as an anticancer agent and gadolinium (III) nitrate hexahydrate (Gd) as the starting material for a contrast agent,. Gold nanoparticles (AuNPs) were subsequently used as second diagnostic agent. The GO nanosheets were firs...

Management of burn injury is an onerous clinical task since it requires continuous monitoring and extensive usage of specialized facilities. Despite rapid improvizations and investments in burn management, >30% of victims hospitalized each year face severe morbidity and mortality. Excessive loss of body fluids, accumulation of exudate, and the development of septic shock are reported to be the ...

Noncovalent binding interactions between proteins are the central physicochemical phenomenon underlying biological signaling and functional control on the molecular level. Here, we perform an extensive structural analysis of a large set of bound and unbound ubiquitin conformers and study the level of residual induced fit after conformational selection in the binding process. We show that the re...

The physicochemical nature of chitin and chitosan, which influences the biomedical activity of these compounds, is strongly related to the source of chitin and the conditions of the chitin/chitosan production process. Apart from widely described key factors such as weight-averaged molecular weight (MW) and degree of N-acetylation (DA), other physicochemical parameters like polydispersity (MW/MN...

The effect of comparatively small pressure changes on the composition of low pressure hollow cathode DC discharges is investigated with a combination of experimental diagnostic techniques and simple models of the plasma kinetics. The plasma precursors considered are H2, Ar/H2 mixtures, and air. In all cases, sudden characteristic composition changes are observed in the pressure interval between...

In recent years, the upgrading of lignocellulose bio-oils from fast-pyrolysis by means ketonization has emerged as a frontier research domain to produce new generation biofuels. Propionic acid (PA) is extensively investigated model reaction over metal oxides, but activity other materials, such phosphates, mostly unknown. Therefore, PA was preliminarily in gas phase both phosphates and oxides Al...

1221 THERE HAS BEEN A GROWING INTEREST IN ETHNIC AND RACIAL DIVERSITY IN RELATION TO SLEEP PARAMETERS. THE STUDY OF DIFFERENCES IN SLEEP between racial groups may lead to an increased understanding of genetic and environmental contributions to sleep physiology and its disorders. Numerous studies of sleep have examined differences in sleep parameters and sleep related symptoms by gender and age,...
