-Poly[[(8-amino-quinoline)-cobalt(II)]-di-μ-azido].

The title coordination polymer, [Co(N)(CHN)] , was synthesized solvothermally. The Co atom exhibits a distorted octa-hedral [CoN] coordination geometry with a bidentate 8-amino-quinoline ligand and four azide ligands. Bridging azide ligands result in chains extending along [100].

Arabidopsis HAK5 under low K availability operates as PMF powered high-affinity K transporter.

Plants can survive in soils of low micromolar potassium (K) concentrations. Root K intake is accomplished by the K channel AKT1 and KUP/HAK/KT type high-affinity K transporters. Arabidopsis HAK5 mutants impaired in low K acquisition have been identified already more than two decades ago, the molecular mechanism, however, is still a matter of debate also because of lack of direct measurements of HAK5-mediated K currents.

Lessons Learned from Community Partnership During the COVID-19 Pandemic.

Underserved communities have been disproportionately affected by the COVID-19 pandemic. The Project Promoting Engagement and COVID-19 Testing for Health (PEACH) study was designed to understand the attitudes, beliefs, and infrastructure associated with COVID-19 risk, testing, and prevention behaviors in people living with, caring for, or at risk for type 2 diabetes. The purpose of this joint community-academic partnered manuscript is to share lessons learned for maintaining community partnerships through the challenging times of a pandemic.

Phase Space Spin-Entropy.

Quantum physics is intrinsically probabilistic, where the Born rule yields the probabilities associated with a state that deterministically evolves. The entropy of a quantum state quantifies the amount of randomness (or information loss) of such a state. The degrees of freedom of a quantum state are position and spin.
