Stereoselective synthesis of a- and b-linked glucopyranosylamide derivatives via the in situ generation of glucosyl isoxazolines has been performed utilizing a
The role of small-angle x-ray and neutron scattering (SAXS and SANS) in the characterization of cement is briefly reviewed. The unique information obtainable
Despite intensive research for over a century, the main binding reaction product of cement hydration, calcium-silicate-hydrate (C-S-H) gel, is not fully

A study was conducted of the room temperature photoluminescence behavior of AlxGa1-xAs as a function of tensile, equi-biaxial stress for x = 0, 0.198, 0.36, 0
The R&E tax credit was originally designed incorrectly, and subsequent attempts to restructure it have not addressed the major deficiencies. Moreover, in the 25
Given an unconditionally stable algorithm for solving the Cahn-Hilliard equations, we provide the mathematical basis for arbitrary accuracy -- we present a

The effects of amine base quencher on the photoacid catalyzed deprotection reaction-diffusion front in model photoresists was measured by combination of neutron
Evaluation has always been an important part of scientific research, and in information retrieval, this evaluation has mostly been done using test collections
We employ scanning confocal laser microscopy (SLCM) to obtain topographic images of the surface of an aluminum alloy subjected to various levels of uniaxial
The Fourier transform microwave spectrum of dimethyl methylphosphonate studied by us previously is reanalyzed here to obtain more physically reasonable

The theoretical existence of photon-number-splitting attacks creates a security loophole for most quantum key distribution (QKD) demonstrations that use a
We evaluate the frequency dependence of the nonlinear response in High Temperature Superconductor YBa2Cu3O7-x thin films by simultaneously measuring the
The Vickers indentation fracture toughness test or VIF is addressed by considering its origins and the numerous equations that have been applied along with the
We have recently introduced several important improvements in the measurement of distillation curves distillation curves for complex fluids. The modifications
