Electrogenerated chemiluminescence (ECL) microscopy shows promise as a technique for mapping chemical reactions on single nanoparticles. The technique’s spatial resolution is limited by the quantum yield of emission and diffusive nature ECL process. To improve signal intensity, dyes have been coupled with plasmonic nanoparticles, which act nanoantennas. Here, we characterize optical properties ...

Calcium carbonate hexahydrate (ikaite) is a rare mineral that forms as metastable species in the organic-carbon-rich sediments of King George Basin, Bransfield Strait, Antarctica, consequence early diagenetic decomposition organic matter under cold water (−1.4 °C) and high pressure (200 bar) conditions. Large crystals grow sediment immediately below transition between microbial sulfate reductio...

The reproducibility of patch test results is of critical importance due to their use as a diagnostic tool in allergic contact dermatitis. This study attempted to validate the reliability of the results obtained with allergEAZE (AE), a new standardized brand of syringe-administered allergens for patch tests. This approach is used as a method of diagnosing contact dermatitis; the diagnosis being ...

We present a case of cytomegalovirus (CMV) retinitis in an AIDS patient who survived for 10 months after the start of his ocular problems. The retinitis responded to dihydroxy propoxy methyl guanine (DHPG) but relapsed four to six weeks after each course of treatment with progressive retinal destruction. One relapse was therefore treated with trisodium phosphoformate hexahydrate (Foscarnet). Th...

The effects of methylcobalamin (vitamin B12) injection (75mg kg ) on cobalt levels in autism spectrum disorders (ASDs) and potential toxic effects of cobalt on human neurons were evaluated. A cohort of ASDs (n1⁄4 72) presenting to the Genetic Centers of America were evaluated for the frequency of methylcobalamin injections and cobalt levels using Laboratory Corporation of America (LabCorp) test...

This paper focuses on the synthesis and mechanism of carbon nanospheres (CNS) coated with fewand multi-layered graphene (FLG, MLG). The graphitic carbon encapsulates the core/shell structure of the Ni/NiO nanoparticles via the chemical vapor deposition (CVD) method. The application of the resulting CNS and hybrids of CNS-FLG and CNS-MLG as reinforcement nanofillers in a polypropylene (PP) matri...

Sodium bis(L-cysteinato)zincate(II) hexahydrate (1) and bis(0-ethvl-L-cysteinato)zinc(II) (2) have been prepared from respectively alkaline (pH > 1 1 ) and neutral aqueous solutions and their structures determined by X-ray structural analysis. N ,S-coordination of the Zn atoms with the formation of two five-membered chelate rings is observed for both com plexes. The deprotonated carboxylate gro...

Fluorescent-labeled molecules have been used extensively for a wide range of applications in biological detection and diagnosis. A new form of highly luminescent and photostable nanoparticles was generated by doping the fluorescent dye tris(2'2-bipyridyl)dichlororuthenium(II)hexahydrate (Rubpy) inside silica material. Because thousands of fluorescent dye molecules are encapsulated in the silica...
