Role of Fe Impurity Reactions in the Electrochemical Properties of MgFeBO.

We investigate magnesium-iron pyroborate MgFeBO as a potential cathode material for rechargeable magnesium-ion batteries. Synchrotron powder X-ray diffraction and Mössbauer spectroscopy confirm its successful synthesis and iron stabilization in the high-spin Fe(II) state. Initial electrochemical testing against a lithium metal anode yields a first charge capacity near the theoretical value (147.

Swimming-Induced Pulmonary Edema in a Member Participating in a Special Tactics Selection Course.

Background: Swimming-induced pulmonary edema (SIPE), also called immersion pulmonary edema, is a form of exertional pulmonary edema associated with swimming and/or water immersion without aspiration. Most case reports on SIPE feature young, healthy patients who were scuba-diving, surface swimming, snorkeling, or breath-hold diving before experiencing symptoms of dyspnea, chest pain/tightness, cough, and hemoptysis. The incidence of SIPE is thought to be between 0.

Borates . aluminates: comparing the anion for lithium-ion batteries.

Lithium borate and aluminate salts bearing a hexafluoroisopropoxy ligand have been prepared and investigated for use in lithium-ion batteries and Cu‖Li cells. Lithium aluminate salts have poorer air tolerance but Li[Al(hfip)] resulted in superior battery cycling, with lower overpotentials for plating and stripping in Cu‖Li cells.

Multiplex digital profiling of DNA methylation heterogeneity for sensitive and cost-effective cancer detection in low-volume liquid biopsies.

Molecular alterations in cancerous tissues exhibit intercellular genetic and epigenetic heterogeneity, complicating the performance of diagnostic assays, particularly for early cancer detection. Conventional liquid biopsy methods have limited sensitivity and/or ability to assess epigenetic heterogeneity of rare epiallelic variants cost-effectively. We report an approach, named REM-DREAMing (Ratiometric-Encoded Multiplex Discrimination of Rare EpiAlleles by Melt), which leverages a digital microfluidic platform that incorporates a ratiometric fluorescence multiplex detection scheme and precise digital high-resolution melt analysis to enable low-cost, parallelized analysis of heterogeneous methylation patterns on a molecule-by-molecule basis for the detection of cancer in liquid biopsies.

Displacive Jahn-Teller Transition in NaNiO.

Below its Jahn-Teller transition temperature, , NaNiO has a monoclinic layered structure consisting of alternating layers of edge-sharing NaO and Jahn-Teller-distorted NiO octahedra. Above where NaNiO is rhombohedral, diffraction measurements show the absence of a cooperative Jahn-Teller distortion, accompanied by an increase in the unit cell volume. Using neutron total scattering, solid-state Nuclear Magnetic Resonance (NMR), and extended X-ray absorption fine structure (EXAFS) experiments as local probes of the structure we find direct evidence for a displacive, as opposed to order-disorder, Jahn-Teller transition at .
