SAXS Research at NSRRC
Small-angle X-ray scattering (SAXS), a scattering tool of atomic spatial resolution and high penetration power, provides a non-destructive scattering tool in structural characterization for surfaces, interfaces, as well as bulks, and is an decent complimentary technique to the direct imaging tools such as the SEM, TEM, and AFM in nanostructure research. Capable in probing structural information...
متن کاملHigh-flux Magnetorheology at Elevated Temperatures
Commercial applications of magnetorheological (MR) fluids often require operation at elevated temperatures as a result of surrounding environmental conditions or intense localized viscous heating. Previous experimental investigations of thermal effects on MR fluids have reported significant reductions in the magnetorheological stress with increasing temperature, exceeding the predictions made b...
متن کاملSAXS study of crotapotin at low pH.
The structure of crotapotin, a protein extracted, from the venom of the Crotalus durissus terrificus, in solution at pH = 1.5, was studied by SAXS. The experimental results yield structural parameter values of the molecular radius of gyration Rg = 13.6 A, volume v = 16.2 x 10(3) A3 A3 and maximal dimension Dmax = 46 A. The distance distribution function deduced from the scattering measurements ...
متن کاملStructure of Laminar Coflow Spray Flames at Different Pressures
Experiments were conducted on laminar spray diffusion flames of ethanol/argon burning in oxygen at pressures of 1 and 3 atm. The flames were physically characterized by measuring droplet velocities and sizes by phase-Doppler anemometry, and gas temperature by thin-filament pyrometry and thermocouples. The flames exhibited a cold core, where little vaporization occurred, surrounded by a primary ...
متن کاملHigh sodium chloride concentrations inhibit staphylococcal enterotoxin C gene (sec) expression at the level of sec mRNA.
Expression of the staphylococcal enterotoxin type C gene (sec) is regulated in response to both high NaCl concentrations (osmolarity) and the accessory gene regulator (agr). agr is a global regulator that alters the expression of many genes in Staphylococcus aureus. In this report, we have demonstrated that osmoregulation of sec occurs at the level of mRNA independently of an intact agr allele....
