Provision of a daily high protein and high energy meal: Effects on the physical and psychological wellbeing of community-dwelling, malnourished older adults; a randomised crossover trial.

Objectives: To determine whether daily provision of a high protein, high energy meal for 12-weeks to under-nourished older adults living independently in the community can improve physical, physiological, and psychological outcomes.

Design: A randomised crossover trial.

Setting: Participant homes within a 15-mile radius to meal supplier; Dartmoor Community Kitchen Hub.

The Utility of Multimodality Imaging in a Patient with Ebstein Anomaly.

• Ebstein anomaly (EA) has varied presentations that require complex decision-making. • Imaging is important before surgery to optimize timing and choose method of repair. • Postoperatively, patients with EA require follow-up with multimodality imaging.

Elucidating local diffusion dynamics in nickel-rich layered oxide cathodes.

Elucidating Li-ion transport properties is essential for designing suitable methodologies to optimise electrochemical performance in Ni-rich cathodes for high energy density Li-ion batteries. Here, we report the local-scale Li-diffusion characteristics of a series of nickel-rich layered oxide cathodes, prepared microwave methods, using muon spin relaxation methods. Our results detail the effects of cation dopants, selected for structure stability, on transport properties in candidate nickel-rich chemistries.

Liquid-Phase Approach to Glass-Microfiber-Reinforced Sulfide Solid Electrolytes for All-Solid-State Batteries.

Deformable, fast-ion conducting sulfides enable the construction of bulk-type solid-state batteries that can compete with current Li-ion batteries in terms of energy density and scalability. One approach to optimizing the energy density of these cells is to minimize the size of the electrolyte layer by integrating the solid electrolyte in thin membranes. However, additive-free thin membranes, as well as many membranes based on preprepared scaffolds, are difficult to prepare or integrate in solid cells on a large scale.

Direct Observation of Dynamic Lithium Diffusion Behavior in Nickel-Rich, LiNiMnCoO (NMC811) Cathodes Using Muon Spectroscopy.

Ni-rich layered oxide cathode materials such as LiNiMnCoO (NMC811) are widely tipped as the next-generation cathodes for lithium-ion batteries. The NMC class offers high capacities but suffers an irreversible first cycle capacity loss, a result of slow Li diffusion kinetics at a low state of charge. Understanding the origin of these kinetic hindrances to Li mobility inside the cathode is vital to negate the first cycle capacity loss in future materials design.
