This study investigates the effect of roughness on interfacial properties of an n-alkanethiolate self-assembled monolayer (SAM) and uses hydrophobicity to demonstrate the existence of upper and lower limits. This article also sheds light on the origin of the previously unexplained gradual increase in contact angles with increases in the size of the molecule making the SAM. We prepared Au surfac...

Anatase TiO(2) nanosheets-based hierarchical spheres with over 90% {001} facets synthesized via a diethylene glycol-solvothermal route were used as photoanodes of dye-sensitized solar cells, which generated an energy conversion efficiency of 7.51%.

OBJECTIVE To discover the cause of acute renal failure in 36 children aged 2 months to 6 years who were admitted to two hospitals in Delhi between 1 April and 9 June 1998. METHODS Data were collected from hospital records, parents and doctors of the patients, and district health officials. Further information was obtained from house visits and community surveys; blood and stool samples were c...

Cage-like silica hollow spheres loaded with superparamagnetic iron oxide nanoparticles incorporated in their macroporous shells are synthesized in a facile manner through a one-step oil-in-diethylene glycol (DEG) microemulsion route.

Alcohol-related intoxications, including methanol, ethylene glycol, diethylene glycol, and propylene glycol, and alcoholic ketoacidosis can present with a high anion gap metabolic acidosis and increased serum osmolal gap, whereas isopropanol intoxication presents with hyperosmolality alone. The effects of these substances, except for isopropanol and possibly alcoholic ketoacidosis, are due to t...

New macrocyclic polyether-diester ligands (3-5) containing the 4H-pyran-4-one subcyclic unit have been prepared by treating various glycols with dimethyl chelidonate (10). In the reaction of compound 10 with ethylene glycol and diethylene glycol, two noncyclic diester and tetraester (6-9) were produced in each case. The new marcocyclic ligand 4 formed stable complexes with benzylammonium pe...

We present a group theoretical analysis of several classes of organic superconductor. We predict that highly frustrated organic superconductors, such as κ-(ET)(2)Cu(2)(CN)(3) (where ET is BEDT-TTF, bis(ethylene-dithio)tetrathiafulvalene) and β'-[Pd(dmit)(2)](2)X, undergo two superconducting phase transitions, the first from the normal state to a d-wave superconductor and the second to a d+id st...

Magnetite nanocrystal clusters are being investigated for their potential applications in catalysis, magnetic separation, and drug delivery. Controlling size distribution is of paramount importance often requires tedious trial-and-error experimentation to determine the optimal conditions necessary synthesize with desired properties. In this work, magnetite were prepared via a one-pot solvotherm...

Few cases, if any, of death from drinking diethylene glycol have been reported in this country. This substance is, of course,, largely used as an antifreeze fluid in radiators of rmotor-cars, and is sold under a variety of trade names in this country, in America, and probably elsewhere , without any restrictions. There is little or no mention of the toxicity of this substance in British literat...
