Epitaxial Lift‐Off Process for Triple‐Junction Solar Cells Using Internal Push–Pull Stressors
Epitaxial lift‐off of multijunction solar cells is achieved using internal push‐pull stressors to enable thin‐film release. An oxide sidewall protection layer ensures selective etching of the sacrificial layer while preventing damage to Al and P containing active layers.

On possibility of synthesis of yttrium-barium cuprates in electro discharge plasma jet [PDF]
In this paper, the possibility is shown to synthesize yttrium-barium cuprates using a high-speed electro discharge plasma jet. The synthesized products were charactirezed by X-Ray diffractometry, scanning electron microscopy and transmission electron ...

Single-crystal X-ray diffractometry using synchrotron radiation
The high brilliance over a wide spectral range up into the hard X-ray region, the small source size and low divergence, the polarization properties and the pulsed time structure are outstanding properties of synchrotron radiation that extend the range of single-crystal X-ray diffractometry to experiments which are not feasable with conventional sources,

Injectable and In Situ Hydration‐Reinforced Hybrid Bone Cements for Accelerated Bone Regeneration
To enable minimally invasive bone defect repair, an injectable and hydration‐reinforced bone cement (L‐PEGS/CPC) is designed through biomimetic reconstruction. The hydrophilic L‐PEGS organic phase provides abundant nucleation sites, synergizing with its porous architecture to accelerate CPC hydration, thereby endowing the composite with exceptional ...

Mechanisms of near‐normal sea water dolomitisation: Mesohaline‐reflux or syn‐depositional?
This study investigates the dolomitisation of the Eocene Dammam Formation on the Arabian Plate using petrographic, mineralogical, geochemical and isotopic analyses. The findings reveal two distinct dolomite types, formed primarily through normal‐to‐mesohaline sea water dolomitisation, challenging previous models such as sabkha‐meteoric mixing.

Polygonal tepee structures of Arabia
Tepee structures on Sheybarah Island form polygonal microbial cemented crusts in the intertidal. Radiocarbon dating suggests they formed in the Holocene and reflect minor sea‐level changes, highlighting their value as palaeoenvironmental indicators. Satellite surveys identified 126 polygonal features, including coral reefs that may have developed on ...

The role of defects in the electrical properties of NbO2 thin film vertical devices
Epitaxial NbO2 thin films were grown on Si:GaN layers deposited on Al2O3 substrates using pulsed laser deposition. Pulsed current-voltage (IV) curves and self-sustained current oscillations were measured across a 31 nm NbO2 film and compared with a ...
