Abstract Nanometer sized cadmium sulfide particles were prepared in N,N‐dimethylformamide, using thiourea as the sulfurizing agent and thioglycerine as stabilizer. For particles with diameters of less than 40 Å the size dependent solubility was utilized to separate the particles according to their size. The absorption…

A rigorous modal analysis of lamellar gratings, i.e. gratings having rectangular grooves, in conical mountings is presented. It is an extension of the analysis of Botten et al. which considered non-conical mountings. A key step in the extension is a decomposition of the electromagnetic field in the grating region into…

Twenty-five gram-negative bacteria and one gram-positive bacterium capable of growing on poly(3-hydroxyoctanoic acid) [P(3HO)] as the sole source of carbon and energy were isolated from various soils, lake water, and activated sludge. Most of the isolates degraded only P(3HO) and copolymers of medium-chain-length (MCL…

A dynamic model that computes the flashover voltages of polluted insulators energized with DC voltage is presented. The salient feature of this model is that it takes into account the configuration of the insulator profile at every instant, which plays an important role in the flashover process of the DC polluted insu…

There has been much recent effort in the design of optimal chromophores for second-order nonlinear optical (NLO) applications. Most studies of organic molecules have focused on donor-acceptor π-conjugated molecules containing aromatic groups. We will show that the NLO response of aromatic donor-acceptor chromophores i…

It is known that two proteins of the cellulosomal complex of Clostridium thermocellum (SL and SS) together degrade crystalline cellulose. SL is a glycoprotein of 210,000 Da which enhances the binding to cellulose and the activity of SS, an endoglucanase of 83,000 Da. We have previously reported the cloning of a DNA fr…
