Conductive Porous Solid Framework Mechanically Stabilized Si Anode.

Micron-sized Si anodes garner renewed attention due to their advantages of low cost, small specific surface area, and high energy density. However, micron-sized Si anodes undergo significant volume changes during lithiation/delithiation, leading to particle cracking and pulverization. This study employs the tape casting method and ultrafast high-temperature sintering technology to construct a porous sheet, within which a solid framework constrains the Si particles.

Maximizing interface stability in all-solid-state lithium batteries through entropy stabilization and fast kinetics.

The positive electrode|electrolyte interface plays an important role in all-solid-state Li batteries (ASSLBs) based on garnet-type solid-state electrolytes (SSEs) like LiLaZrTaO (LLZTO). However, the trade-off between solid-solid contact and chemical stability leads to a poor positive electrode|electrolyte interface and cycle performance. In this study, we achieve thermodynamic compatibility and adequate physical contact between high-entropy cationic disordered rock salt positive electrodes (HE-DRXs) and LLZTO through ultrafast high-temperature sintering (UHS).

Improved Electrochemical Performances of LiCoO at Elevated Voltage and Temperature with an In Situ Formed Spinel Coating Layer.

Although various cathode materials have been explored to improve the energy density of lithium-ion batteries, LiCoO is still the first choice for 3C consumer electronics due to the high tap density and high volumetric energy density. However, only 0.5 mol of lithium ions can be extracted from LiCoO to avoid side reactions and irreversible structure change, which typically occur at high voltage (>4.

DR5 and DcR2 are expressed in human lumbar intervertebral discs.

Study Design: To conform the 3 media way of the apoptosis for the degenerative lumbar disc with DR5 (TRAIL-R2) and DcR2 (TRAIL-R4), as one of the tumor necrosis factors family.

Objective: To detect the expression of the DR5 (TRAIL-R2) and DcR2 (TRAIL-R4) protein and mRNA in human herniated and normal lumbar intervertebral discs (IVD).

Summary Of Background Data: The pathogenesis of lumber intervertebral disc herniation and degeneration is still unclear.
