Unlocking Four-electron Conversion in Tellurium Cathodes for Advanced Magnesium-based Dual-ion Batteries.

Magnesium (Mg) batteries hold promise as a large-scale energy storage solution, but their progress has been hindered by the lack of high-performance cathodes. Here, we address this challenge by unlocking the reversible four-electron Te/Te conversion in elemental Te, enabling the demonstration of superior Mg//Te dual-ion batteries. Specifically, the classic magnesium aluminum chloride complex (MACC) electrolyte is tailored by introducing Mg bis(trifluoromethanesulfonyl)imide (Mg(TFSI)), which initiates the Te/Te conversion with two distinct charge-storage steps.

Electrodeposition of Ni-Mo alloy coatings from choline chloride and propylene glycol deep eutectic solvent plating bath.

Ni-Mo alloy coatings were deposited on a copper base material from a non-aqueous plating bath based on a deep eutectic solvent (DES) of choline chloride and propylene glycol in a 1:2 molar ratio containing 0.2 mol dm NiCl · 6HO and 0.01 mol dm (NH)MoO·4HO.

Composite and Surface Functionalization of Ultrafine-Grained Ti23Zr25Nb Alloy for Medical Applications.

In this study, the ultrafine-grained Ti23Zr25Nb-based composites with 45S5 Bioglass and Ag, Cu, or Zn additions were produced by application of the mechanical alloying technique. Additionally, the base Ti23Zr25Nb alloy was electrochemically modified in the two stages of processing: electrochemical etching in the solution of HPO and HF followed by electrochemical deposition in Ca(NO), (NH)HPO, and HCl. The in vitro cytocompatibility studies were also done with comparison to the commercially pure titanium.

Crystal Structure Evolution, Microstructure Formation, and Properties of Mechanically Alloyed Ultrafine-Grained Ti-Zr-Nb Alloys at 36≤Ti≤70 (at. %).

Titanium β-type alloys are preferred biomaterials for hard tissue replacements due to the low Young modulus and limitation of harmful aluminum and vanadium present in the commercially available Ti6Al4V alloy. The aim of this study was to develop a new ternary Ti-Zr-Nb system at 36≤Ti≤70 (at. %).

Ionic Liquids: A Simple Model to Predict Ion Conductivity Based on DFT Derived Physical Parameters.

A model able to a priori predict ion conductivities of ionic liquids (ILs) is a desired design tool. We here propose a set of simple conductivity models for ILs composed of small ions by only using data easily derived from standard DFT calculations as input; ion volume, ion mass, ion moment of inertia, and the ion-ion interaction strength. Hence these simple models are totally without any need for experimental parametrization.

Deviations of inorganic and organic carbon content in hypomineralised enamel.

Objectives: The purpose of this study was to discriminate hypomineralised enamel of permanent first molars from normal enamel by means of spectroscopic methods.

Methods: The present study was conducted using Multi spot Raman Fourier Transform Spectroscopy, Diffuse Reflectance Infrared Fourier Transform Spectroscopy (FTIR) and X-ray diffraction (XRD).

Results: Raman spectroscopy indicated significantly more B-type carbonate and hydrocarbons in hypomineralised enamel diagnosed as MIH (Molar Incisor Hypomineralisation).

"Ionic liquids-in-salt"--a promising electrolyte concept for high-temperature lithium batteries?

A novel electrolyte concept for lithium-ion batteries, termed "ionic liquid-in-salt", is introduced. Our feasibility study on (1 - x)EMIMTFSI:(x)LiTFSI, 0.66 ≤ x ≤ 0.

Novel antiplatelet agents in the prevention of cardiovascular complications--focus on ticagrelor.

Atherothrombosis, thrombus formation as a result of atherosclerotic plaque rupture, is a major modern health problem, often underlying coronary artery disease, stroke, and peripheral arterial disease. After the treatment of an acute thrombotic episode, long-term therapy is warranted as a secondary prophylaxis of such events and their complications. Because of the importance of platelets' involvement in the initiation and propagation of thrombosis, antiplatelet drugs have come to the forefront of atherothrombotic disease treatment.
