Impact of optimised quasi-block structures on the properties of polymer electrolytes.

A set of ionic quasi-block copolymers were investigated to determine the effects of their composition and structure on their performance in their application as solid-state battery electrolytes. Diffusion and electrochemical tests have shown that these new quasi-block electrolytes have comparable performance to traditional block copolymers reaching ionic conductivities of 3.8 × 10 S cm and lithium-ion diffusion of 4.

Morphological Evolution and Solid-Electrolyte Interphase Formation on LiNiMnCoO Cathodes Using Highly Concentrated Ionic Liquid Electrolytes.

Employing high-voltage Ni-rich cathodes in Li metal batteries (LMBs) requires stabilization of the electrode/electrolyte interfaces at both electrodes. A stable solid-electrolyte interphase (SEI) and suppression of active material pulverization remain the greatest challenges to achieving efficient long-term cycling. Herein, studies of NMC622 (1 mAh cm) cathodes were performed using highly concentrated -methyl--propylpyrrolidinium bis(fluorosulfonyl)imide (CmpyrFSI) 50 mol % lithium bis(fluorosulfonyl)imide (LiFSI) ionic liquid electrolyte (ILE).

Effects of therapeutic touch on blood hemoglobin and hematocrit level.

Background: Therapeutic Touch (TT) is a widely used complementary therapy. This study investigated the effects of TT on hemoglobin and hematocrit level in students who were basically healthy.

Method: The volunteers with a hemoglobin level less than 12 grams per deciliter (g/dl) were randomly assigned to three groups of TT, mimic therapeutic touch (MT), and control.
