A quantitative interpretation of diffuse neutron scattering has yielded an accurate description of the defect structure of CaO stabilized zirconia (CSZ) at 290 and 1550 K. The defect structure is based on the correlated distribution of two different types of microdomains within the disordered structure. The first micr…

Machine learning (ML) is transforming all areas of science. The complex and time-consuming calculations in molecular simulations are particularly suitable for an ML revolution and have already been profoundly affected by the application of existing ML ...Read More
In order to investigate the role of the Eu2+ luminescent centers in determining the electro-optical characteristics of red-emitting CaS:Eu thin-film electroluminescent (TFEL) devices with inherent memory, light irradiation effects on these characteristics were studied. Both the threshold voltage and the response time…

A straightforward numerical-graphical method is applied to achieve a flat fission power density (FPD) in a catalyzed deuterium-deuterium fusion-driven hybrid blanket by using a mixed fuel made of a nuclear waste actinide (244CmCO2) and natural UO2 with variable fractions of fuel components in the radial direction. The…

Plasma etching of ITO (In 2 O 3 :Sn indium tin oxide) thin films has been performed using a CH 4 /H 2 plasma. Etching occurs above a substrate temperature ( T s ) of 60°C and the etch rate increases with increasing T s , while amorphous like or polymer-like carbon deposits onto the ITO films below 60°C. The apparent a…

A novel process using polyaniline for plating through hole technology has been developed. Polyaniline was dip-coated onto printed circuit boards and in turn acted as a thin conducting electrode for the electrolytic metallization of Cu on the through holes. This eliminates the necessity for expensive precious metal see…
Dense, fine‐grained silicon carbide (SiC) ceramics were fabricated by a hot‐pressing technique using pyrolyzed polycarbosilane powders. Hot‐isostatic pressing treatments were also applied to some of these hot‐pressed samples. The grainsize range of the obtained sintered bodies was from 0.2 to 1.4 μm, which was much fi…

Soluble organic matrix isolated from dorsal carapaces of the blue crab, Callinectes sapidus, inhibited CaCO3 crystallization when free in solution. Immobilized matrix complexes, prepared by crosslinking soluble matrix to decalcified crab carapace, promoted CaCO3 formation in that crystallization in the presence of the…
Localization lengths of electronic states on one-dimensional Fibonacci quasicrystals are calculated exactly within a decimation-renormalization scheme. A self-similar pattern is obtained for the localization lengths along the spectrum as the numerical resolution is improved. Properties of the states in the spectrum ar…
Abstract Consequences for classification, structure and properties are assessed in the simplest case of an uncrystallizable chemically unspecific polymer, atactic polystyrene (a‐PS), for these studies, in closely monodisperse form. The mechanism first proposed by Berghmans and collaborators, namely liquid‐liquid phase…
Fatigue crack propagation rates in tension‐tension load cycling were measured in ZrO 2 ‐12 mol% CeO 2 ‐10 wt% Al 2 O 3 ceramics using precracked and annealed compact tension specimens. The fatigue crack growth behavior was examined for Ce‐TZPs of different transformation yield stresses obtained by sintering for 2 h at…
A ceramic, Joule‐heated, slurry‐fed melter will be used to vitrify Savannah River Site high‐level waste at the Defense Waste Processing Facility (DWPF) in Aiken, SC. The entire vitrification process must be performed remotely and the borosilicate host glass must accommodate a variety of waste compositions. The control…
