Nonrelativistic Spin Current Generated Unconventional Spin Hall Magnetoresistance in Altermagnetic RuO2

Advanced Science, EarlyView.
It is reported that the unconventional spin Hall magnetoresistance generated from nonrelativistic spin currents in RuO2 is capable of accurately detecting spin current polarization and disentangling the T̂$\hat{T}$‐odd and T̂$\hat{T}$‐even components of a spin current.

Synthesis, Structural and Optical Characterization of Titanium Dioxide Doped by (Ce, Yb) Dedicated to Photonic Conversion

Indonesian Journal of Chemistry, 2019
The synthesis of TiO2 co-doped by (Ce, Yb) rare earth couple has been realized. This couple of rare earth can convert a high-energy photon to two low energy photons to enhance the energy efficiency of silicon solar cells. The undoped, 2% Ce doped- and (2%

One‐Dimensional RuIrTe Nanotubes with Amorphous Surface as a Highly Active and Stable Electrocatalyst Toward Oxygen Evolution Reaction in Acidic Media

Advanced Science, EarlyView.
A rational etching‐induced reconstruction strategy is demonstrated to fabricate one‐dimensional RuIrTe ternary nanotubes with a unique amorphous‐crystalline heterostructure. This hierarchical architecture synergistically optimizes mass transport and electronic configurations, delivering record‐breaking performance in proton exchange membrane water ...

Macroscopic elastic anisotropy in tough ceramics from the single crystal elastic behaviour [PDF]

, 2011
The modern techniques for engineering analysis are based on a deep understanding of the proportional relationship between stress and strain and the description in terms of isotropic elastic constants, in many cases, is enough.

Degradation Mechanisms of Rutile‐Type TiO2 Photoanodes during Photoelectrochemical Water Splitting

Advanced Energy Materials, EarlyView.
Combining operando dissolution measurements with microscopy and spectroscopy characterizations, we reveal different degradation mechanisms of rutile‐type TiO2 photoanodes during photoelectrochemical water splitting. In acidic electrolytes, degradation is inhibited once TiO2 reaches saturation.
