BINGA, Zimbabwe — More than a decade after Zimbabwe's government began seizing sprawling white-owned commercial farms, a new fight is brewing here over who will profit from the nation's vast bounty of platinum, chromium, nickel and diamonds.
About 2 billion years ago the Bushveld Complex which is one of the largest differentiated igneous bodies on Earth, containing major deposits of platinum, chromium, and vanadium was emplaced in the northern Kaapvaal craton.
Although the TAXUS Liberté and ION paclitaxel-eluting stents use similar polymer and drug, the ION stent incorporates a novel thin-strut platinum chromium metal alloy and cell design.
The aim of this study was to evaluate the safety and efficacy of the novel platinum chromium TAXUS Element paclitaxel-eluting stent (PES) compared with the TAXUS Express PES (Boston Scientific, Natick, Massachusetts) in treating coronary artery stenoses.
We sought to evaluate the clinical outcomes with a novel platinum chromium everolimus-eluting stent (PtCr-EES) compared with a predicate cobalt chromium everolimus-eluting stent (CoCr-EES) in patients undergoing percutaneous coronary intervention (PCI).
Inorganic nanoparticles such as magnetic nanoparticles (iron oxide), gold, platinum, chromium, manganese, zinc, selenium, titanium, molybdenum, palladium, silica, copper, cerium oxide, and silver nanoparticles, bimetallic, nanoshells, and nanocages have been continuously used and modified to enable their use as a therapeutic and diagnostic agent.
The authors sought to evaluate the final 5-year safety and effectiveness of the platinum-chromium everolimus-eluting stent (PtCr-EES) in the randomized trial, as well as in 2 single-arm substudies that evaluated PtCr-EES in small vessels (diameter <2.5 mm; n = 94) and long lesions (24 to 34 mm; n = 102).
The PROMUS Element Plus US Post-Approval Study (PE-Plus PAS) was a prospective, open-label, multicenter, observational study designed to examine outcomes in everyday clinical practice in patients treated with everolimus-eluting, platinum-chromium PROMUS Element Plus stents at 52 centers in the United States.
His two original partners, Mrs Fong and Mrs Lo, became directors in a new company, called Sino-Zimbabwe Development Limited, which received rights to extract oil and gas, and to mine gold, platinum and chromium.
With the increasing demand for small ignition devices, the investigation of heavily semiconductor or metallic film bridge, especially doped polycrystalline silicon, titanium, platinum, and chromium bridge, has attracted much attention in recent years [1 7].
Although two-step and other sequential methods are known for the preparation of such catalysts, the newly developed method described here will led more efficiently to catalysts, having a small particle size, of the platinum cobalt chromium alloy.
