Crystallography of Stress Corrosion Cracking in Pure Magnesium
A crystallographic characterization study has been made of the transgranular stress corrosion cracking in pure Mg tested at room temperature in aqueous NaCl-K2CrO4. Selected area electron channeling and photogrammetry were used to determine the cracking orientation. The fracture surfaces consisted of flat parallel {22…
The identification and X-ray structure of the diphosphatotris(nonatungstophosphato)nonacobaltate(II) heteropolyanion
The P5Co9W27O119H1716– anion has 3/m symmetry, and contains nine CoO6 octahedra sharing oxygen atoms with one another and with three α-B PW9O34 moietries and two PO4 groups.
Structural characterisation of [Au10Cl3(PCy2Ph)6](NO3)(Cy = cyclohexyl) and the development of a structural principle for high nuclearity gold clusters
[Au10Cl3(PCy2Ph)6](CO3) which has been synthesised in low yield from Au(NO3)(PCy2Ph) and NaBH4 has a toroidal geometry based on a hexagonal ring of edge- and face-sharing tetrahedra which share a common central vertex.
Liposomes as drug carriers in cancer therapy.
Liposomes, microscopic particles composed of lipid bilayer membranes, can carry water-soluble drugs in their aqueous compartments and lipid soluble drugs in their bilayers. Over the last 10 years, they have been studied more intensively than any other type of drug carrier. The first impulse, as with other pharmaceutic…
Early steps in the free radical polymerisation of 3,4-dihydroxyphenylalanine (dopa) into malanin
Pulse radiolysis and flash photolysis-initiated one-electron oxidation of 3,4-dihydroxyphenylalanine (dopa) and other catecholamines have allowed the direct measurement of the kinetics of semiquinone disproportionation leading successively to the corresponding melanin precursors dopaquinones and dopachromes.
5—FABRIC SOFTNESS, HANDLE, AND COMPRESSION
The result of subjective finger-pressure assessments of fabric softness are compared with objective measurements of compression. Good correlation between them is reported for a set of non-woven and a set of woven fabrics. Relations between the touch, compressibility, mass, thickness, density, and specific volume of th…
Kinetics of polymorphic solid-state transformations
Solid-state polymorphic transformations can have a profound influence on the processing and storage of some crystalline powders. Using classical models of nucleation and growth a framework is developed which highlights the importance of crystal size on the transformation rate. A key parameter in this theory is the rat…
L-Sorbose metabolism in Klebsiella pneumoniae and Sor+ derivatives of Escherichia coli K-12 and chemotaxis toward sorbose
L-Sorbose degradation in Klebsiella pneumoniae was shown to follow the pathway L-sorbose leads to L-sorbose-1-phosphate leads to D-glucitol-6-phosphate leads to D-fructose-6-phosphate. Transport and phosphorylation of L-sorbose was catalyzed by membrane-bound enzyme IIsor of the phosphoenolpyruvate-dependent carbohydr…
In vivo measurement of regional brain tissue pH using positron emission tomography
Carbon-11-labeled dimethyloxazolidinedione ([11C]DMO) was injected intravenously into human subjects, and serial positron emission tomographic (PET) scans were obtained until brain-blood equilibration was achieved or could be accurately predicted from dynamic PET and 11C blood data. Knowledge of regional brain-blood p…
Luminescence of Pb2+ Centers in SrS and SrSe Phosphors
The emission and excitation spectra of the SrS: Pb 2+ and SrSe: Pb 2+ phosphors were measured at low temperatures. The 3 A 1u → 1 A 1g emission band at 374 or 392 nm is observed at 80 K in addition to the 3 T 1u → 1 A 1g emission band at 368 or 383 nm for SrS: Pb 2+ or SrSe: Pb 2+ , respectively. On these emission ban…
Control of reactivity at the porphyrin periphery by metal ion co-ordination: a general method for specific nitration at the β-pyrrolic position of 5,10,15,20-tetra-arylporphyrins
The site of nitration by nitrogen dioxide on a range of metalloporphyrins has been found to be dependent on the co-ordinated metal; copper(II), nickel(II), and palladium(II) complexes are nitrated specifically on the porphyrin β-pyrrolic position while magnesium(II), zinc(II), chloroiron(III), and cobalt(II) complexes…
Moisture Regimes and Morphological Characteristics in a Hydrosequence in Central Massachusetts
Abstract Moisture regimes and associated soil mottling patterns were investigated over a 2‐y period in a Paxton‐Rainbow‐Ridgebury‐Scarboro hydrosequence in central Massachusetts. Changes in physical conditions in these coarse‐loamy fragipan soils were monitored with well points, tensiometers, soil temperature probes,…
Surface-enhanced Raman scattering and the preparation of copper substrates for catalytic studies
Copper surfaces producing enhancement of the Raman scattering cross-section for adsorbed molecules comparable to the largest enhancements observed on silver have been prepared. These substrates are suitable for investigations of reactant intermediates in heterogeneous catalytic reactions, since they exhibit strong enh…
Refinement of the crystal structure of wollastonite-2M (parawollastonite)
The structure of woBastonite-2M from Death ValJey, CaJifornia, USA, Ca3(Si30g), is monoclinic with space group P21!a, a = 15.409(3), b=7.322(1), c=7.063(1)A, {3=95.30(2)', Z=4 and Dx=2.92g cm-3, and was refined to R (unweighted) =0.038 and R(weighted)=0.031 using 3886 non- equivalent reflections. WoBastonite-2M contai…
Studies of the simulation of silane coupling agent structures on particulate fillers; the pH effect
Abstract The molecular structure of γ‐methacryloxypropyltrimethoxysilane (γ‐MPS) deposited on the surfaces of particulate mineral fillers was modeled by adjusting the pH of an aqueous alcoholic solution of the silane in absence of a substrate. Hydrolyzates obtained from the solution were studied by gel permeation chro…
Corrosion in power generating equipment
This book reviews the causes of corrosion-related events responsible for a significant loss of power plant availability. Problems that occur in the steam generating, geothermal, and nuclear components of power generating systems are discussed. Topics considered include the fundamental aspects of localized environmenta…
