Traditional approaches to the formation of mesostructured inorganic films from block-copolymer and surfactant templates rely on simultaneous assembly of amphiphilic structure-directing agents and inorganic sol–gel precursor species into ordered hybrid structures. Variations in sample composition and processing conditions have afforded considerable control over the local (nanometer-scale) morpho...

Almost ever since the advent of the microelectronics adventure, silicon-based MOSFET (metal–oxide–semiconductor fieldeffect transistor) technology has been largely dominant. However, for a few years now this technology has exhibited some fundamental limitations in tackling the increasingly challenging issues of miniaturization and improvements in processing speed and power consumption. Hence, n...

We have developed methods to exfoliate MoS 2 in large quantities in surfactant-water solutions. This method can be extended to a range of other layered compounds. The layered material tends to be exfoliated as relatively defect free flakes with lateral sizes of 100s of nm. in layered crystals and can be metals, semiconductors or insulators. [1] In addition, some are thermoelectric materials, [2...

A field-scale plot study was conducted at Virginia Tech’s Prices Fork Research Farm, to evaluate the transport of nutrients in runoff from manure and fertilizer applied at P-based agronomic rates to cropland planted to corn. Simulated rainfall events representing 2to 10-year storms in southwest Virginia, occurring 1 and 2 days following manure and fertilizer application were used to generate ru...

Heritable ectopic mineralization disorders represent a phenotypically diverse group of conditions characterized by deposition of calcium phosphate complexes in soft connective tissues. The prototype of such conditions is pseudoxanthoma elasticum, and related conditions with overlapping clinical features include generalized arterial calcification of infancy and arterial calcification due to CD73...

In recent years, a number of reactions leading to the liberation of inorganic pyrophosphate have been described. Since the only known reaction leading to a net decrease in the concentration of inorganic pyrophosphate is that of hydrolysis, the properties of inorganic pyrophosphatases are of interest. The discovery of an inorganic pyrophosphatase in muscle was made by Lohmann (2) and one was dem...

Inorganic dispersion is of great importance for actual implementation of advanced properties of organic-inorganic composites. Currently, electron microscopy is the most conventional approach for observing dispersion of inorganic fillers from ultrathin sections of organic-inorganic composites at the nanoscale by professional technicians. However, direct visualization of macrodispersion of inorga...

Strong inorganic acid mists containing sulfuric acid are known to be human carcinogens based on sufficient evidence of carcinogenicity from studies in humans that indicate a causal relationship between exposure to strong inorganic acid mists containing sulfuric acid and human cancer. Occupational exposures to strong inorganic acid mists containing sulfuric acid are specifically associated with ...
