The interface between bottom anti-reflective coatings (BARCs) and a model deprotected photoresist, poly(4-hydroxystyrene) (PHS), was investigated using near...
In this review article, we discuss the implications for the morphology of an immiscible polymer blend, or in general, an emulsion, in the limit when the two...
Scanning tunneling microscopy/spectroscopy on Kondo systems consisting of magnetic atoms adsorbed upon non-magnetic metal surfaces has demonstrated the ability...
Three iterations of PERMIS Workshop Papers (2000, 2001 and 2002) contain theoutlines of the theory of performance measures.: PERMIS'2003 will begin to...

We present a new, two dimensional phase field model of grain boundary statics and dynamics. We begin with a brief description and physical motivation of the...
In the extrusion of linear low-density polyethylene (PE), fluoropolymer-processing additives (PPA) are used to eliminate the surface defect known as sharkskin...
For many contemporary physics experiments, the use of an optical cavity has become a powerful tool for enhancement in detection sensitivities, nonlinear...
We propose a dual electromagnetically induced transparency (EIT) based multiwave mixing scheme that retains the significantly enhanced conversion efficiency...

The triose sugars with empirical formula, C 3H 6O 3, consist of the aldehyde form, glyceraldehyde, and the ketone form, 1,3-dihydroxy-2-propanone. Recently, the...
The reaction with hydroxyl radicals in the troposphere is the main atmospheric removal process for the majority of gases of industrial and natural origin. Their...
The magnitude of the stimulated Raman gain spectrum will depend on the absolute wavelength of the pump laser. For many fibers, this dependence can be cast as a...

An experimental examination of a 10 Ω}; and a 2 Ω}; time-domain reflectometer (TDR) for measuring low-impedance transmission line characteristics is presented...
Several studies have shown the importance of particle losses in real homes due to deposition; however, none have shown the impact of using a central forced air...
We investigate the existence of quantum quasi phase transitions for an ensemble of ultracold bosons in a one-dimensional optical lattice, performing exact...

Multiple sequence alignments of the eight glutathione (GSH) transferase homologues encoded in the genome of Escherichia coli were used to define a consensus...
We present an iterative algorithm for calibrating vector network analyzers based on orthogonal distance regression. The algorithm features a robust, yet...
