Inhibiting Lattice Distortion of Ultrahigh Nickel Co-Free Cathode Material for Lithium-Ion Batteries.
Nano Lett
January 2025
College of Chemistry and Materials Science, Hebei University, Baoding 071002, Hebei, P. R. China.
Ultrahigh nickel cathode materials are widely utilized due to their outstanding energy and power densities. However, the presence of cobalt can cause significant lattice distortion during charge and discharge cycles, leading to the loss of active lithium, the formation of lattice cracks, and the emergence of a rock salt phase that hinders lithium-ion transport. Herein, we developed a novel cobalt-free, aluminum-doped cathode material, LiNiMnAlO (NMA), which effectively delays the harmful H2-H3 phase transition, reduces lattice distortion, alleviates stress release, and significantly enhances structural stability.

Exp Physiol
January 2025
Centre for Healthy Ageing, Health Futures Institute, Murdoch University, Perth, Australia.
Blood flow restriction (BFR) combined with low work rate exercise can enhance muscular and cardiovascular fitness. However, whether neural mechanisms mediate these enhancements remains unknown. This study examined changes in corticospinal excitability and motor cortical inhibition following arm cycle ergometry with and without BFR.

Age Ageing
January 2025
Division of Psychiatry, University College London, London, UK.
Background: Age-related hearing loss and mild cognitive impairment (MCI) independently increase dementia risk. The Ageing and Cognitive Health Evaluation in Elders randomised controlled trial (RCT) found hearing aids reduce cognitive decline in high-risk older adults with poor hearing.
Methods: This pilot RCT in London memory clinics randomised people with MCI (aged ≥55, untreated hearing loss defined as Pure Tone Average 0.
Role of Grape () Extracts of Different Cultivars Against γ-Radiation Induced DNA Damage and Gene Expression in Human Lymphocytes.

Radiation therapy uses ionizing radiation (IR) to kill cancer cells. However, during radiotherapy normal cells are also damaged and killed by the generation of reactive oxygen species. Polyphenolic compounds are known to mitigate the damaging effects of radiation.

Front Physiol
January 2025
Center for Transplantation Sciences, Department of Surgery, Massachusetts General Hospital, Harvard Medical School, Charlestown, MA, United States.
Introduction: Exercise is widely recognized for its benefits to chronic kidney disease (CKD) patients. However, the specific impact of different exercise modalities on CKD-related outcomes remains unclear. This study sought to summarize the effects of different exercise modalities on the main outcomes impacted by CKD.
