Disordered Rocksalts as High‐Energy and Earth‐Abundant Li‐Ion Cathodes
Advanced Materials, EarlyView.Disordered rocksalts with lithium excess (DRX) offer a new direction in Li‐ion cathode design beyond conventional Ni‐ and Co‐based materials. This review highlights the design principles, synthesis strategies, and performance optimization of DRX oxides and oxyfluorides for energy‐dense, sustainable batteries using Earth‐abundant transition metals and ...

Surface flow visualization of separated flows on the forebody of an F-18 aircraft and wind-tunnel model [PDF]
A method of in-flight surface flow visualization similar to wind-tunnel-model oil flows is described for cases where photo-chase planes or onboard photography are not practical.

Advanced Materials Interfaces, EarlyView.Ultrathin amorphous alumina electrocatalyst overlayers block oxygen reduction while cathodic‐driven structural relaxation accelerates proton transport over time. By contrast, ultrathin aluminosilicate coatings allow proton permeation but cannot suppress oxygen.

A simplified method for calculating temperature time histories in cryogenic wind tunnels [PDF]
Average temperature time history calculations of the test media and tunnel walls for cryogenic wind tunnels have been developed. Results are in general agreement with limited preliminary experimental measurements obtained in a 13.5-inch pilot cryogenic ...

Subsurface State Bilayer in Tetragonal Ferroelectric BaTiO3
Advanced Materials Interfaces, EarlyView.The subsurface Ba2+disorder, reveals the pairs of O vacancies (VO++$V_O^{ + + }$ s) and small polarons (SPe‐SPe−$SP_e^ - $ s) (Figure a–b), with the charge balance, as the following: Ti3++[VO+++SPe−]pair↔Ti4+${{T}_i}^{3 + } + {{[V_O^{ + + } + SP_e^ - ]}_{pair}} \leftrightarrow T_i^{4 + }$ which is consistent with observed low‐energy electron ...

X‐Ray and Electron Spectroscopy of the CdS/(Ag,Cu)(In,Ga)Se2 Interface With RbF Treatment
Advanced Materials Interfaces, EarlyView.The chemical and electronic structure of the CdS/(Ag,Cu)(In,Ga)(S,Se)2 interface with RbF treatment is investigated using a combination of synchrotron‐ and laboratory‐based soft and hard X‐ray spectroscopies. A Rb–In–Se species is found at the absorber surface, with a band gap of 2.8 eV, in contrast to comparable Ag‐free Cu(In,Ga)Se2 absorbers with RbF‐
