Advanced Functional Materials, EarlyView.This study demonstrates an alternative method of creating charge‐stable negatively charged nitrogen vacancy (NV−) centers close to the diamond surface without high‐temperature annealing. By illuminating nitrogen‐implanted regions with a continuous‐wave 405 nm laser, NV− centers are induced, exhibiting electron spin coherence properties suitable for ...

The Extragalactic Background Radiation —1989 [PDF]
Symposium - International Astronomical Union, 1990 This symposium has brought back many happy memories of the time 20 years ago when Rashid Sunyaev and I surveyed what was known about the extragalactic background radiation at that time. In one of our papers of 1969, we published a simple representation of the extragalactic background radiation spectrum, as it was known then (Figure 1).

Advanced Functional Materials, EarlyView.HKUST‐1/TiO2 composite materials show a very high photocatalytic hydrogen evolution rate which increases as a function of the irradiation time until reaching a plateau and even surpasses the performance of the 1%Pt/TiO2 material after three photocatalytic cycles.

Advanced Functional Materials, EarlyView.Multifunctional atomic layer deposited coatings and interface treatments enhance direct solar water splitting on GaAs/GaInP tandem cells. Optimized TiO2/Pt nanoparticle bilayers ensure durability and catalytic efficiency with minimal optical losses, while H2 plasma pretreatments maximize photovoltage and interfacial charge extraction.

Comparative study between radiation exposure in common urological procedures
Beni-Suef University Journal of Basic and Applied SciencesBackground Fluoroscopy has become essential to urological surgery since advancement of endourology. Fluoroscopy use has increased, placing urologists as well as staff members at risk for occupational radiation exposure and related dangers.

Advanced Functional Materials, EarlyView.The chemical composition and band alignment are systematically investigated at the TiO2/InP heterointerface. Thin TiO2 films are deposited by ALD on atomically ordered, P‐terminated p‐InP(100). By combining UPS, XPS, and ab initio molecular dynamics, the atomistic structure and electronic alignment are revealed.
