With the increasing attention to environmental hygiene and air quality, disinfection of bioaerosols has become a highly focused research area. Therefore, it is critical importance find a...
The Raman scattering technique was used to investigate the low-lying intermolecular modes in liquid and vitreous glycerol from 65–353°K. It found that while integrated intensity of polarized spectrum decreases with decreasing temperature, depolarization ratio remains more or less constant (≅ 0.68). A large decrease occurs near glass transition temperature. Considering a normal mode vibration is responsible for both ir absorption scattering, we have derived an expression which relates...
The technique of hyper-Rayleigh scattering is used to determine and compare the first hyperpolarizabilities (β) five structurally similar m-substituent phenyl-amine based chromophores using both internal external standards. Contribution from two photon absorption induced fluorescence observed signal carefully removed. with m-substituted phenyl ring, that stabilizes maximal charge-transfer state through resonance effect, are found have larger static β values redshifted electronic peaks (λmax)...
Centrosymmetric furan-containing cyclophandienes 3 and 4, synthesized by our furan annulation protocol, have been shown to exhibit extraordinarily large Stokes shifts second-order nonlinear optical beta values. The values for 4 measured at 1.32 mum are 208 530x10(-30) esu, respectively. of similar those respective cyclophenes 1 a 7 in which strong hyperpoarizable interactions between two twisted pi-systems (oligoaryl bridging double bond) might take place. Symmetry breaking due the resonance...
Abstract The effect of physical aging on the tracer diffusion coefficient D camphorquinone in polysulfone is investigated. It shown that if sample sufficiently annealed and nearly complete, temperature dependence will reflect primary α‐relaxation process host polymer. In range between T g (=185°C) 165°C, found to be a function time, time given by = At −μ , with μ approximately equal unity. © 1994 John Wiley & Sons, Inc.
Laser induced holographic grating relaxation studies of camphorquinone (CQ) diffusing in liner polystyrene (PS) (with both narrow and wide molecular weight distribution) crosslinked PS bis-phenol-A-dimethacrylate as the crosslinking agent) are carried out. Diffusion coefficients CQ polymer hosts obtained from decay rate intensity diffracted laser grating. The diffusion (D) polydispersed samples compared with that nearly monodispersed sample. found to be equal types over whole temperature...
Abstract In this study titanium–zirconium–molybdenum alloys (Ti 50 Zr ) 100‐ x Mo ( Mo; = 0 at.%, 1 3 5 at.% or 7 at.%) were investigated, focusing on the effect of molybdenum addition their microstructures and mechanical properties. Transmission electron microscopy observations revealed that binary Ti alloy was composed entirely an acicular hexagonal structure α’ phase. When content β ω phases. However, when more added, only equiaxed, retained phase observed. Tensile tests at room...
Abstract Quasielastic light (QEL) scattering studies of semidilute solutions polystyrene in benzene and plus diethyl phthalate mixed solvents have been carried out. Comparisons are made between experiment theoretical results. It is found that the relative amplitude viscoelastic modes depends on coupling parameter β (defined text). For with β=0, no component observed QEL spectrum, consistent prediction. The a relaxation time distribution spectrum PS solvent to depend time. Steady state values...
