In this work, green synthesized cobalt monometallic and cobalt–zinc bimetallic NPs were prepared by bioreduction of metallic salts with Cymbopogan citratus plant extract. Biosynthesized nanoparticles (NPs) characterized using diverse techniques such as FTIR, UV-Visible spectroscopy, SEM, XRD, EDX analyses. UV-visible spectra for green-synthesized in the range between 300 to 350 nm, which confir...
Elizabeth Conrad and the children had eagerly awaited the Mediterranean cruise that would take them to Greece and the Greek Isles. Theodore Conrad had been invited to lecture in Athens and this would mean opportunities to visit the Acropolis, Parthenon and Agora; then traveling to Rhodes to see its Colossus, the Asclepion, a renowned center of healing, and finally Kos, the birthplace of Hippocr...
Figure 1: In this x-ray composite image made with the electron microprobe, red represents aluminum, green, magnesium, and blue, iron. A glassy impact-melt vein with several large vesicles cuts through the breccia on the right side.

Barium chromate, Prussian blue, and cobalt-cobalticyanide can be precipitated in vivo in the endothelium of mesenteric vessels by injection of the appropriate anions into the blood stream, and topical application of the precipitating cations to the exposed mesenteries of mice and frogs. Precipitation in the endothelium occurs in the form of a diffuse fine punctate precipitate, and also as conti...
The published crystal structure in the paper by Zibaseresht & Hartshorn (2006) is almost certainly that of the nickel complex and not the copper complex as originally identified. Refinement of the copper occupancy was consistent with the presence of a lighter transition metal ion in the structure, and residuals improved significantly when the complex was refined as the nickel or cobalt salts. U...
Nowadays, materials with great potential for environmental protection are being sought. Metal–organic frameworks, in particular those cobalt species as active sites, have drawn considerable interest due to their excellent properties. This review focuses on describing cobalt-based MOFs the context of light-triggered processes, including dye degradation, water oxidation and splitting, carbon diox...
Shards of Blue-and-White Ming porcelain from shipwrecks Portuguese ships found on the coasts South Africa plus a shard Mombasa (Kenya) were analyzed by optical microscopy, SEM-EDS and Raman microspectroscopy (458 nm). Whereas signature body paste compositions which are based mullite, quartz an amorphous phase with minor presence anatase feldspar very comparable whatever variable alumina content...
