Dynamic Transition Metal Network via Orbital Population Design Stabilizes Lattice Oxygen Redox in Stoichiometric Layered Cathodes.

Li-ion batteries employing stoichiometric layered Li metal oxides as cathodes are now reaching the energy density limits due to single cationic redox chemistry. Lattice oxygen redox (LOR) has been discovered in these materials, as a high-energy-density paradigm observed in Li-rich materials. Nevertheless, the origin of this process is not understood, preventing the rational design of better cathode materials.

Van der Waals phase transition investigation toward high-voltage layered cathodes.

High-voltage phase transition constitutes the major barrier to accessing high energy density in layered cathodes. However, questions remain regarding the origin of phase transition, because the interlayer weak bonding features cannot get an accurate description by experiments. Here, we determined van der Waals (vdW) interaction (vdWi) in LiCoO via visualizing its electron density, elucidating the origin of O3─O1 phase transition.

New Insight into Bulk Structural Degradation of High-Voltage LiCoO at 4.55 V.

The aggravated mechanical and structural degradation of layered oxide cathode materials upon high-voltage charging invariably causes fast capacity fading, but the underlying degradation mechanisms remain elusive. Here we report a new type of mechanical degradation through the formation of a kink band in a Mg and Ti co-doped LiCoO cathode charged to 4.55 V (vs Li/Li).

Efficacy Analysis of Physical Therapy in Treating Chronic Prostatitis: Unblocking Obstructed Glandular Ducts Could Be a Novel Treatment Strategy.

Objective: This study investigates the efficacy of physical therapy in treating chronic prostatitis grounded on the glandular duct blockage theory.

Methods: The study includes patients who were diagnosed and treated for chronic prostatitis between November 2022 and July 2023 at Renhui clinic in Jiangmen, Guangdong and Renhui frontline clinic in Shenzhen Guangdong. The recorded data includes the frequency of physical therapies including prostate massages, rectal probe high-frequency vibration treatment, and low-intensity extracorporeal shockwave therapy (Li-ESWT).

An Anomalous Electron Configuration Among 3d Transition Metal Atoms.

Physical properties of materials are mainly determined by valence electron configurations, where different valence shells would induce divergent phenomena. In compounds containing Sc , 3d electron occupancy is expected, the same as other transition metal atoms like Ti . But this situation still awaits experimental verification in inorganic materials.
