Cobalt, the forgotten mineral, found to offer anti-inflammatory and antioxidant health benefits
(Natural News) A study conducted by two American doctors showed that cobalt, a mineral that’s a crucial component of the batteries that power smartphones, doesn’t get credit for having two of the most important attributes that contribute to overall health: antioxidant and anti-inflammatory properties. “The human health-supporting properties of dietary cobalt are underappreciated,” said the paper’s authors, Dr....

Globus Medical lands Anthem coverage win for Secure-C spinal implant
Globus Medical (NYSE:GMED) last week said it won a coverage decision for its Secure-C cervical spine implant from health insurance giant Anthem (NYSE:ANTM). Audubon, Pa.-based Globus said the decision means the device is covered by the major third-party payers in all 50 states. Anthem has more than 73 million lives under its coverage umbrella, according to Globus. The Secure-C device won pre-market approval from the FDA in 2012 and is is designed to restore normal movement to the neck in patients with disc problems that produce neck and arm pain. It consists of 2 cobalt-chrome endplates and a centr...

Strangers in the Land: A Congolese Murder Case
A man walks down the street. It's a street in a strange world. Maybe it's the Third World. Maybe it's his first time around. He doesn't speak the language. He holds no currency. He is a foreign man. He is surrounded by the sound. The sound! Cattle in the marketplace, scatterlings and orphanages. He looks around, around.By Jan LundiusSTOCKHOLM / ROME, Jan 21 2019 (IPS)I thought about this song by Paul Simon while I in 2011 spent a few weeks in Kinshasa.

Powerful X-ray beams unlock secrets of nanoscale crystal formation
(Georgia Institute of Technology) High-energy X-ray beams and a clever experimental setup allowed researchers to watch a high-pressure, high-temperature chemical reaction to determine for the first time what controls formation of two different nanoscale crystalline structures in the metal cobalt. The technique allowed continuous study of cobalt nanoparticles as they grew from clusters including tens of atoms to crystals as large as five nanometers. (Source: EurekAlert! - Biology)

A linear cobalt(II) complex with maximal orbital angular momentum from a non-Aufbau ground state
Orbital angular momentum is a prerequisite for magnetic anisotropy, although in transition metal complexes it is typically quenched by the ligand field. By reducing the basicity of the carbon donor atoms in a pair of alkyl ligands, we synthesized a cobalt(II) dialkyl complex, Co(C(SiMe2ONaph)3)2 (where Me is methyl and Naph is a naphthyl group), wherein the ligand field is sufficiently weak that interelectron repulsion and spin-orbit coupling play a dominant role in determining the electronic ground state. Assignment of a non-Aufbau (dx2–y2, dxy)3(dxz, dyz)3(dz2)1 electron configuration is supported by dc magnetic su...

Ultralow-loading platinum-cobalt fuel cell catalysts derived from imidazolate frameworks
Achieving high catalytic performance with the lowest possible amount of platinum is critical for fuel cell cost reduction. Here we describe a method of preparing highly active yet stable electrocatalysts containing ultralow-loading platinum content by using cobalt or bimetallic cobalt and zinc zeolitic imidazolate frameworks as precursors. Synergistic catalysis between strained platinum-cobalt core-shell nanoparticles over a platinum-group metal (PGM)–free catalytic substrate led to excellent fuel cell performance under 1 atmosphere of O2 or air at both high-voltage and high-current domains. Two catalysts achieved ox...

Should You Develop Your Own Material Specification and Skip ASTM ’s?
The basic format for an ASTM standardized metal alloy for medical uses includes a specification of the required elements as well as one or more undesirable elements for which there is a maximum allowable amount. For example, ASTM F2886, last approved in 2017, covers Metal Injection Molded Cobalt-28Chromium-6Molybdenum Components for Surgical Implant Applications. While the name gives part of the recipe, a more-detailed list of elements specifies that chromium must be between 27 and 30%, and molybdenum between 5 and 7%. Thus, these major required alloying elements together constitute 32 to 37% of the mix. Twelve other eleme...

Transformation of simple precursors into structurally complex cyclobutanes, present in many biologically important natural products and pharmaceuticals, is of considerable interest in medicinal chemistry. Starting from 1,3-enynes and ethylene, both exceptionally inexpensive starting materials, we report a cobalt-catalyzed route to vinylcyclobutenes, as well as the further enantioselective addition of ethylene to these products to form complex cyclobutanes with all-carbon quaternary centers. These reactions can proceed in discrete stages or in a tandem fashion to achieve three highly selective carbon-carbon bond formations ...
