Advanced Functional Materials, EarlyView.A bespoke multilayer thin film configuration has been designed, which overcomes the material dependency of conventional isotope exchange Raman spectroscopy (IERS). This universal IERS methodology is efficient, non‐destructive and provides additional structural information and time resolution, which can be further extended to various isotopic elements ...

Lead-tellurium oxysalts from Otto Mountain near Baker, California: VI. Telluroperite, Pb_3Te^(4+)O_4Cl_2, the Te analog of perite and nadorite [PDF]
, 2010 Telluroperite, Pb_3Te^(4+)O_4Cl_2, is a new tellurite from Otto Mountain near Baker, California. The new mineral occurs on fracture surfaces and in small vugs in brecciated quartz veins in direct association with acanthite, bromine-rich chlorargyrite ...

Solvothermal Synthesis of α-Quartz Powder Doped with Germanium
Zeitschrift für Naturforschung B, 2008 Experimental investigations concerning the synthesis of Si1−xGexO2 solid solutions with quartz structure have been carried out under solvothermal conditions from sol-gel preparations. The cell parameters of the powders have been determined by X-ray powder diffraction. The amount of germanium inside the SiO2 structure was measured also by electron probe

Grain Boundary Space Charge Engineering of Solid Oxide Electrolytes: Model Thin Film Study
Advanced Functional Materials, EarlyView.This study demonstrates unprecedented control of grain boundary electrical properties in solid electrolytes. Selective diffusion of cations through grain boundaries in thin films enables 12 orders of magnitude variation in ionic resistance, proving that systematic chemical modification of grain boundary electrical properties is feasible.

Local Thermal Conductivity Patterning in Rotating Lattice Crystals of Anisotropic Sb2S3
Advanced Functional Materials, EarlyView.Microscale control of thermal conductivity in Sb2S3 is demonstrated via laser‐induced rotating lattice crystals. Thermal conductivity imaging reveals marked thermal transport anisotropy, with the c axis featuring amorphous‐like transport, whereas in‐plane directions (a, b) exhibit 3.5x and 1.7x larger thermal conductivity.

Advanced Functional Materials, EarlyView.Vacuum‐based deposition is promising for perovskite solar cells to be successfully commercialized. However, co‐evaporation, the most common vapor phase deposition technique, suffers from very low deposition rates. In this work, we reveal that high deposition rates can lead to carbon flakes depositing into the perovskite absorber layers due to material ...

Superconducting Properties of MgCNi3 Films
, 2003 We report the magnetotransport properties of thin polycrystalline films of the recently discovered non-oxide perovskite superconductor MgCNi3. CNi3 precursor films were deposited onto sapphire substrates and subsequently exposed to Mg vapor at 700 C.

Electrochemical Formation of BiVO4/BiPO4 Photoanodes for Enhanced Selectivity toward H2O2 Generation
Advanced Functional Materials, EarlyView.In acidic KPi, V dissolves from the BiVO4 lattice, while adsorbed phosphate reacts with the electrode under an external bias, forming a BiPO4 surface layer. This BiPO4 layer exhibits stronger bicarbonate adsorption, redirecting the water oxidation pathway toward two‐electron H2O2 production.
