Targeted multielement substitution of a lead-free relaxor ferroelectric perovskite distorts the lattice structure and induces strong polar disorder, leading to high-polar-entropy ferroelectric oxides with a high electrocaloric effect and long lifetime.

Here, the authors performed plasma proteomics and metabolomics analysis and identify the vinculin (VCL) pathway as a key mediator of lung exudation in SARS-CoV-2 infections, particularly associated with Omicron infection. In a mouse model of infection inhibition of VCL leads to reduced lung pathology.

The mantle has contributed more largely to tungsten mineralization processes and tungsten pre-enrichment in the crust than previously thought, based on multi-isotope data analysis of major tungsten provinces worldwide coupled with machine learning.

Here, the authors introduce a hydroxy-silicon proton acceptor as OER catalyst which greatly accelerates the deprotonation process in OER and prolong the cycle life of zinc-ion batteries.
