Polymeric materials near the liquid-solid transition (LST) exhibit a very distinct relaxation pattern. The reference point for analyzing these patterns is the instant of LST at which relaxation becomes self-similar over wide ranges of the relaxation time. The universality of this transition and its consequences have been explored extensively during the past decade. This study will present an ov...

Calculations have been presented for the intermediate scattering function, dynamic structure factor, and dynamic susceptibility of a complex correlated system undergoing relaxation with independent vibrations. The vibrational contribution was approximated by a Debye spectrum, smoothed at high frequency, while the coupling model was used to describe the relaxation. This model asserts for nonpoly...

Colloidal suspensions that are out of thermodynamic equilibrium undergo physical aging wherein their structure evolves to lower the free energy. In aqueous suspension of Laponite, physical aging accompanies increases of elastic and viscous moduli as a function of time. In this work, we study temporal evolution of elastic and viscous moduli at different frequencies and observe that freshly prepa...

The hypotensive effect of garlic has been well-documented in human subjects and animals. Since endothelial activity regulates vascular reactivity in physiological and pathophysiological conditions, the aim of the present study was to investigate the effect of garlic on endothelium-dependent and independent relaxation of rat aorta for elucidation of mechanism of the garlic anti-hypertensive effe...

The relationship among dynamic relaxation, deformation and microstructural heterogeneity of amorphous alloy is one the important research contents in field physics. In this paper, we utilize Zr<sub>48</sub>(Cu<sub>5/6</sub>Ag<sub>1/6</sub>)<sub>44</sub>Al<sub>8</sub> bulk with excellent glass forming capability good thermal stability a...

The inverse Faraday effect (generation of a time-independent magnetic moment under the action circularly polarized electromagnetic wave) in mesoscopic superconducting samples with finite gap excitation spectrum is analytically described. Within modified time-dependent Ginzburg–Landau theory (Kramer–Watts-Tobin equations) for thin disks, it shown that temperature dependence optically induced non...

The dynamics of electron solvation following excitation of the charge-transfer-to-solvent precursor state in iodide-doped methanol clusters, I(-)(CH(3)OH)(n = 4-11), are studied with time-resolved photoelectron imaging. This excitation produces a I···(CH(3)OH)(n)(-) cluster that is unstable with respect to electron autodetachment and whose autodetachment lifetime increases monotonically from ~8...
