Optically addressable molecular spins for quantum information processing
Spin-bearing molecules are promising building blocks for quantum technologies as they can be chemically tuned, assembled into scalable arrays, and readily incorporated into diverse device architectures. In molecular systems, optically addressing ground-state spins would enable a wide range of applications in quantum information science, as has been demonstrated for solid-state defects. However, this important functionality has remained elusive for molecules. Here, we demonstrate such optical addressability in a series of synthesized organometallic, chromium(IV) molecules. These compounds display a ground-state spin that ca...

Metal-organic magnets with large coercivity and ordering temperatures up to 242{degrees}C
Magnets derived from inorganic materials (e.g., oxides, rare-earth–based, and intermetallic compounds) are key components of modern technological applications. Despite considerable success in a broad range of applications, these inorganic magnets suffer several drawbacks, including energetically expensive fabrication, limited availability of certain constituent elements, high density, and poor scope for chemical tunability. A promising design strategy for next-generation magnets relies on the versatile coordination chemistry of abundant metal ions and inexpensive organic ligands. Following this approach, we report th...

Reduction by reduction: Novel approach to mitigating chromium contamination in wastewater
(Tokyo University of Science) Chromium in its hexavalent state (Cr(VI)) is a major water pollutant. It can be treated, however, by converting it into the less toxic trivalent chromium or Cr(III) via 'reduction.' While several methods to facilitate this reduction exist, they are costly and restrictive. Now, scientists have come up with a technique to achieve efficient Cr(VI) reduction with a photocatalytic system in water. This method not only is cost-effective but also has direct applications in wastewater treatment. (Source: EurekAlert! - Biology)

How a toxic chromium species could form in drinking water
(American Chemical Society) The water crisis in Flint, Michigan, brought much-needed attention to the problem of potentially toxic metals being released from drinking water distribution pipes when water chemistry changes. Now, researchers reporting in ACS' Environmental Science& Technology have investigated how hexavalent chromium, known as Cr(VI), can form in drinking water when corroded cast iron pipes interact with residual disinfectant. Their findings could suggest new strategies to control Cr(VI) formation in the water supply. (Source: EurekAlert! - Biology)

Study shows heating in vaping device as cause for lung injury
(University of California - Irvine) Early results of an experimental vaping study have shown significant lung injury from E-cigarette (eC) devices with nickel-chromium alloy heating elements. The findings were consistent, with or without the use of nicotine, vitamin E oil or tetrahydrocannabinol (THC), which have previously been thought to contribute to the life-threatening respiratory problem.

Iron-based superelastic alloys with near-constant critical stress temperature dependence
Shape memory alloys recover their original shape after deformation, making them useful for a variety of specialized applications. Superelastic behavior begins at the critical stress, which tends to increase with increasing temperature for metal shape memory alloys. Temperature dependence is a common feature that often restricts the use of metal shape memory alloys in applications. We discovered an iron-based superelastic alloy system in which the critical stress can be optimized. Our Fe-Mn-Al-Cr-Ni alloys have a controllable temperature dependence that goes from positive to negative, depending on the chromium content. This...

Finding toxic carcinogenic metals faster in foods and water
(University of Johannesburg) Finding out if the food and water we consume are safe from toxic and carcinogenic metals can now be much faster and simpler. Researchers at the University Johannesburg developed an efficient and more sensitive method to test for dangerous levels of heavy metals, like arsenic, cadmium and chromium in vegetables and water. The method can be used to test other foods also. A clay-based adsorbent makes testing for several metals at the same time possible. (Source: EurekAlert! - Medicine and Health)

Diabetes and COVID-19 Link
I have results from my clinic…
Three of my diabetic patients went into remission after using hyperbaric oxygen therapy (HBOT).
Two patients had type 1 diabetes… and another had type 2 diabetes. All three recovered with oxygen therapy.
Most mainstream doctors would scoff at the idea… they “know” there’s no cure for diabetes. And to be treated for it with oxygen seems laughable.
If you’re a regular reader, you know more about oxygen therapy than 99% of the general public, including most doctors.
But the reason diabetes responds so well to oxygen may surprise you…
It also explains why ...
