Analysis of the raman frequency shifts for the lattice modes and vibrons related to the thermodynamic quantities in the? phase of solid nitrogen
(2013)The thermodynamic quantities of the isothermal compressibility, thermal expansion and the specific heat are calculated here as a function of pressure by using the observed Raman frequencies of the lattice modes and vibrons ... 
Black hole solutions and Euler equation in Rastall and generalized Rastall theories of gravity
(World Scientific Publishing, 2019)Focusing on the special case of generalized Rastall theory, as a subclass of the nonminimal curvaturematter coupling theories in which the field equations are mathematically similar to the Einstein field equations in the ... 
BoseEinstein condensation of noninteracting charged Bose gas in the presence of external potentials
(Elsevier Science Publishers B.V., 2001)We investigate thermodynamic properties of noninteracting charged bosons in the presence of externally applied electric and magnetic fields. Using the semiclassical density of states, we obtain the condensate fraction, ... 
Characterization of thermally poled germanosilicate thin films
(Optical Society of American (OSA), 2004)We report measurements of the nonlinearity profile of thermally poled lowloss germanosilicate films deposited on fusedsilica substrates by PECVD, of interest as potential electrooptic devices. The profiles of films grown ... 
Charged bosons in a quasionedimensional system
(American Physical Society, 2000)The groundstate properties of a system of charged bosons in a quasionedimensional model with a neutralizing background are investigated within the hypernettedchain approximation. Strong correlation effects drive the ... 
Density profile of a BoseEinstein condensate inside a pancakeshaped trap: Observational consequences of the dimensional crossover in the scattering properties
(Elsevier Science B.V., 2002)It is theoretically well known that twodimensionality of the scattering events in a BoseEinstein condensate introduces a logarithmic dependence on density in the coupling constant entering a meanfield theory of the ... 
Dynamic correlation effects on the plasmon dispersion in a twodimensional electron gas
(The American Physical Society, 2003)The chargedensity oscillations (plasmons) of a lowdensity twodimensional uniform electron gas are studied within the framework of finite temperature and frequency dependent (dynamic) version of Singwi, Tosi, Land, and ... 
Investigation of binding properties of dicationic styrylimidazo[1,2a]pyridinium dyes to human serum albumin by spectroscopic techniques
(John Wiley and Sons Ltd, 2017)The binding interaction between two dicationic styrylimidazo[1,2a]pyridinium dyes and human serum albumin (HSA) was investigated at physiological conditions using fluorescence, UV–vis absorption, and circular dichroism ... 
NonBoltzmann stationary distributions and nonequilibrium relations in active baths
(American Physical Society, 201612)Most natural and engineered processes, such as biomolecular reactions, protein folding, and population dynamics, occur far from equilibrium and therefore cannot be treated within the framework of classical equilibrium ... 
Nonthermal Quantum Channels as a Thermodynamical Resource
(American Physical Society, 2015)Quantum thermodynamics can be understood as a resource theory, whereby thermal states are free and the only allowed operations are unitary transformations commuting with the total Hamiltonian of the system. Previous ... 
Orientational transition and complexation of DNA with anionic membranes: weak and intermediate electrostatic coupling
(American Physical Society, 2019)We characterize the role of charge correlations in the adsorption of a short, rodlike anionic polyelectrolyte onto a similarly charged membrane. Our theory reveals two different mechanisms driving the likecharge ... 
Radiochemical study of Co2+ sorption on chlorite and kaolinite
(Akademiai Kiado Rt., 1999)In this work, the sorption behavior of Co(II) ions on natural chlorite and kaolinite as a function of time, concentration and temperature was studied. 60Co radiotracer method and the batch technique were used. The kinetic ... 
A radiotracer study of the adsorption behavior of aqueous Ba2+ ions on nanoparticles of zerovalent iron
(2007)Recently, iron nanoparticles are increasingly being tested as adsorbents for various types of organic and inorganic pollutants. In this study, nanoparticles of zerovalent iron (NZVI) synthesized under atmospheric conditions ... 
Retinal proteins as model systems for membrane protein folding
(Elsevier BV, 2014)Experimental folding studies of membrane proteins are more challenging than watersoluble proteins because of the higher hydrophobicity content of membrane embedded sequences and the need to provide a hydrophobic milieu ... 
Temperature dependence of the energy of a vortex in a twodimensional Bose gas
(Elsevier, 2004)We evaluate the thermodynamic critical angular velocity Ωc(T) for creation of a vortex of lowest quantized angular momentum in a strictly twodimensional Bose gas at temperature T, using a meanfield twofluid model for ... 
Thermodynamic parameters of Cs+ sorption on natural clays
(Akademiai Kiado Rt., 2002)The sorption behavior of Cs+ on kaolinite, chloriteillite, and bentonite clays as a function of time, cation concentration, and temperature was studied using the radiotracer method. Sorption data were well represented by ... 
Trapped interacting Bose gas in nonextensive statistical mechanics
(The American Physical Society, 2002)We study the BoseEinstein condensation (BEC) phenomenon in an interacting trapped Bose gas using the semiclassical twofluid model and nonextensive statistical mechanics. The effects of nonextensivity characterized by a ...
