A new 'cool' blue
(American Chemical Society) Throughout history, people have sought vibrant blue pigments. The Egyptians and Babylonians used lapis lazuli 6,000 years ago. In 1802, a French chemist synthesized cobalt blue. More recently, in 2009 scientists discovered YInMn Blue, otherwise known as " Oregon Blue. " But most of these pigments have limitations in terms of cost, stability, color or toxicity. Now, researchers inACS Omega report a new class of 'cool' blue colorants that are inexpensive, durable and more environmentally friendly. (Source: EurekAlert! - Social and Behavioral Science)

Mutual control of coherent spin waves and magnetic domain walls in a magnonic device
The successful implementation of spin-wave devices requires efficient modulation of spin-wave propagation. Using cobalt/nickel multilayer films, we experimentally demonstrate that nanometer-wide magnetic domain walls can be applied to manipulate the phase and magnitude of coherent spin waves in a nonvolatile manner. We further show that a spin wave can, in turn, be used to change the position of magnetic domain walls by means of the spin-transfer torque effect generated from magnon spin current. This mutual interaction between spin waves and magnetic domain walls opens up the possibility of realizing all-magnon spintronic ...

Itaconyl-CoA forms a stable biradical in methylmalonyl-CoA mutase and derails its activity and repair
Itaconate is an immunometabolite with both anti-inflammatory and bactericidal effects. Its coenzyme A (CoA) derivative, itaconyl-CoA, inhibits B12-dependent methylmalonyl-CoA mutase (MCM) by an unknown mechanism. We demonstrate that itaconyl-CoA is a suicide inactivator of human and Mycobacterium tuberculosis MCM, which forms a markedly air-stable biradical adduct with the 5'-deoxyadenosyl moiety of the B12 coenzyme. Termination of the catalytic cycle in this way impairs communication between MCM and its auxiliary repair proteins. Crystallography and spectroscopy of the inhibited enzyme are consistent with a metal-centered...

Atomic-scale spin sensing with a single molecule at the apex of a scanning tunneling microscope
Recent advances in scanning probe techniques rely on the chemical functionalization of the probe-tip termination by a single molecule. The success of this approach opens the prospect of introducing spin sensitivity through functionalization by a magnetic molecule. We used a nickelocene-terminated tip (Nc-tip), which offered the possibility of producing spin excitations on the tip apex of a scanning tunneling microscope (STM). When the Nc-tip was 100 picometers away from point contact with a surface-supported object, magnetic effects could be probed through changes in the spin excitation spectrum of nickelocene. We used thi...

Fermi-arc diversity on surface terminations of the magnetic Weyl semimetal Co3Sn2S2
Bulk–surface correspondence in Weyl semimetals ensures the formation of topological "Fermi arc" surface bands whose existence is guaranteed by bulk Weyl nodes. By investigating three distinct surface terminations of the ferromagnetic semimetal Co3Sn2S2, we verify spectroscopically its classification as a time-reversal symmetry-broken Weyl semimetal. We show that the distinct surface potentials imposed by three different terminations modify the Fermi-arc contour and Weyl node connectivity. On the tin (Sn) surface, we identify intra–Brillouin zone Weyl node connectivity of Fermi arcs, whereas on cobalt (Co) termi...
