Effect of Rare-Earth Element Oxides on Diamond Crystallization in Mg-Based Systems

Crystals, 2019
Diamond crystallization in Mg-R2O3-C systems (R = Nd, Sm, Eu, Tb, Dy, Ho, Er, Tm, and Yb) was studied at 7.8 GPa and 1800 °C. It was found that rare-earth oxide additives in an amount of 10 wt % did not significantly affect both the degree of ...

The self-seeded growth of InAsSb nanowires on silicon by metal-organic vapor phase epitaxy

, 2014
We present a study on the growth of InAs1-xSbx alloy nanowires directly on Si (111) substrates via a self seeded mechanism for the first time. Through varying group V flow rate ratios, InAs1-xSbx nanowires with x = from 0 to 0.43 are obtained.

Cathodic Cage Plasma Deposition of Nanostructured Cu–Fe–Se Coatings on Poly(methyl Methacrylate)

Advanced Engineering Materials, EarlyView.
Nanostructured Cu–Fe–Se coatings are deposited on PMMA by a modified cathodic cage plasma process, enabling low‐temperature deposition on polymer substrates. A transition from discontinuous to compact morphology is observed with temperature, with optimal properties at 200°C, where improved CuFeSe2‐type bonding, lowest sheet resistance, and favorable ...

Crystal Form Investigation and Morphology Control of Salbutamol Sulfate via Spherulitic Growth

Crystals
Salbutamol sulfate is a selective β2-receptor agonist used to treat asthma and chronic obstructive pulmonary disease. The crystals of salbutamol sulfate usually appear as needles with a relatively large aspect ratio, showing poor powder properties.

Encyclopedia of 2D β′‐In2Se3 Growth Using Chemical Vapor Deposition: The Effects of Synthesis Parameters Onto Material Quality

Advanced Engineering Materials, EarlyView.
A distinct semi‐confined inner‐tube chemical vapor deposition geometry enables reproducible, large‐area growth of phase‐pure 2D β′‐In2Se3 from InI + Se precursors. Engineering local vapor transport and optimizing precursor delivery and temperature–time conditions yield uniform continuous films.

Electrically injected photonic-crystal nanocavities

, 2012
Nano-emitters are the new generation of laser devices. A photonic-crystal cavity, which highly confines light in small volumes, in combination with quantum-dots can enhance the efficiency and lower the threshold of this device.

Modifiers regulate crystal morphology by generating lattice defects [PDF]

Crystal morphology plays a pivotal role in all applications because it affects the performance and processing behaviors of crystals. Foreign compounds are often employed to control the crystal morphology; conversely, morphology variations are sometimes ...

Characterization of supercooled liquid Ge₂Sb₂Te₅ and its crystallization by ultrafast-heating calorimetry

, 2012
Differential scanning calorimetry (DSC) is widely used to study the stability of amorphous solids, characterizing the kinetics of crystallization close to the glass-transition temperature Tg. We apply ultrafast DSC to the phase-change material Ge2Sb2Te5 (
