Equivalent dose in quartz from young samples using the SAR protocol and the effect of preheat temperature
(Pergamon-Elsevier Science Ltd, 2006-09)
Major concerns in the dating of samples younger than a few hundred years by the optically stimulated luminescence (OSL) technique are thermal transfer and partial bleaching. Thermal transfer during preheating enhances the ...
Hybrid high dimensional model representation (HHDMR) on the partitioned data
(Elsevier B.V., 2006-01-01)
A multivariate interpolation problem is generally constructed for appropriate determination of a multivariate function whose values are given at a finite number of nodes of a multivariate grid. One way to construct the ...
Vapor-induced film formation from low-T-g particles for different solvent compositions
(Elsevier Inc, 2006-05-15)
The photon transmission method was used to study latex film formation from poly(vinyl acetate) (PVAc) particles induced by two different solvents. Films with the same latex content were prepared from PVAc particles and ...
Phase transitions of kappa-carrageenan gels in various types of salts
(John Wiley & Sons Inc, 2006-11-05)
Sol-gel and gel-sol phase transitions of K-carrageenan in various types of salts were studied using photon transmission technique. Here, LiCl, NaCl, KCl, MgCl2, CaCl2, and SrCl2 were chosen as the proper salts for the ...
Universal behaviour of gel formation from acrylamide-carrageenan mixture around the gel point: A fluorescence study
(Taylor & Francis Group, 2006-08)
The steady state fluorescence (SSF) technique was used to study the sol-gel transition, for the solution free radical crosslinking copolymerization of acrylamide (AAm) with various carrageenan content. N, N'- methylenebis ...
Small molecule desorption prior to dissolution of a polymeric glass
(Wiley Subscription Services, Inc., A Wiley Company, 2006-07-15)
Poly(methyl methacrylate) (PMMA) discs in various molecular weights (M-w) were prepared by free-radical polymerization. Pyrene (Py) was introduced during polymerization as a fluorescence probe. In situ steady state ...
Two remarks on a generalized Davey-Stewartson system
(Elsevier Ltd, 2006-03-01)
We present two results on a generalized Davey-Stewartson system, both following from the pseudo-conformal invariance of its solutions. In the hyperbolic-elliptic-elliptic case, under some conditions on the physical parameters, ...
Film formation stages for poly(vinyl acetate) latex particles: a photon transmission study
(Springer-Verlag, 2006-07)
Photon transmission technique was used to monitor the evolution of transparency during film formation from poly(vinyl acetate) (PVAc) latex particles. The latex films were prepared below the glass transition temperature ...
Effects of annealing on morphology of polymer/polymer (PS/PMMA) blend; a fluorescence study
(John Wiley& Sons Inc, 2006-05-05)
Steady state fluorescence (SSF) technique conjunction with optical microscopy were used to study the morphology of polystyrene (PS)/poly(methyl methacrylate) (PMMA) blend upon annealing above glass transition in elevated ...
Electrochromic switching of WO3 nanostructures and thin films
(Springer-Verlag, 2006-04)
We present transmission measurements through tungsten tri-oxide nanostructures and thin films prepared by sol-gel process on micro-contact printed substrates. Identical electrochromic switching times are found for both the ...
