We have monitored the phase transformation from a Sandia octahedral molecular sieve Na2Nb2O6−H2O to a piezoelectric NaNbO3 nanowire through in situ X-ray diffraction (XRD) and transmission electron microscopy (TEM) measurements at high temperatures. After dehydration at 288 °C, the Na2Nb2O6−H2O becomes significantly destabilized and transforms into NaNbO3 with the increase of time. The phase tr...

Potential applications of Zr/Al ODS alloys vests on the irradiation stability Y4Zr3O12 dispersoids. Fundamental studies to identify type defects are important in order recognize pathways for damage alleviation. In this context, relating identification point and their clusters by in-situ ionoluminescence spectroscopy were taken up. The spectrum acquired during 100 keV He+ ion shows two prominent...

All-optical magnetization control has recently been garnering considerable attention to realize next-generation ultrafast magnetic information devices. Here, employing a magneto-optical Kerr effect (MOKE) microscope, we observed the laser-induced switching of ferrimagnetic oxide NiCo2O4 (NCO) epitaxial thin films with perpendicular anisotropy, where sample was pumped by 1030 nm laser pulses, an...

Fire plays an important role in maintaining the savanna tree-grass balance by limiting recruitment of heat-sensitive tree seedlings. However, fire behaviour may change under increasing CO2 concentrations, due to altered flammability grassy layer. Here, we determined effect predicted future and how it interacts with water-availability, on grass traits influential flammability, uncovered physiolo...

Molybdenum disulfide (MoS2) few-layer films have gained considerable attention for their possible applications in electronics and optics also as a promising material energy conversion storage. Intercalating alkali metals, such lithium, offers the opportunity to engineer electronic properties of MoS2. However, influence lithium on growth MoS2 layers has not been fully explored. Here, we studied ...

The broadband laser induced white emission (LIWE) spectra of NdAlO 3 nanocrystals in vacuum, air, and liquid N 2 were explored. In particular, their dependence on excitation power was investigated. It found that the LIWE intensity increased exponentially with above threshold all three cases. process for discussed terms multiphoton ionization assisted by ejection hot electrons. Two differences o...

The flexibility of producing two dispersive waves (DWs) in silicon nitride (Si3N4) slot waveguide is demonstrated, by tailoring the features and corresponding phase-matching condition. DWs are generated at visible mid-infrared (mid-IR) wavelength regions, respectively. We obtain a broadband low normal dispersion region from 2 to 5.25 μm, which offers particular advantages for DW generati...
