The electrical and thermal behavior of nanoscale devices based on two-dimensional (2D) materials is often limited by their contacts interfaces. Here we report the temperature-dependent boundary conductance (TBC) monolayer MoS$_2$ with AlN SiO$_2$, using Raman thermometry laser-induced heating. optical absorption 2D material crucial in such experiments, which characterize here for first time above room temperature. We obtain TBC ~ 15 MWm$^-$$^2$K$^-$$^1$ near temperature, increasing as...

Since 2012, zinc gallogermanate has drawn interests as an excellent host phosphor for a variety of dopants (e.g., Cr 3+ , Bi and Mn 2+ ). However, the origin its self‐activated luminescence been largely unknown. Here, composition Zn 1+ x Ga 2−2 Ge O 4 (0 ≤ 1) is prepared by solid‐state reaction, evolution crystal structure with studied. The phosphors show broad white‐bluish emission upon excitation ultraviolet (UV) light, intensity greatly increases are substituted 4+ . A full spectrum...

Bright green emission is obtained from the Mn2+-doped zinc gallogermanate phosphors. The X-ray diffraction (XRD) and photoelectron spectroscopy (XPS) confirm that so a solid solution of ZnGa2O4 Zn2GeO4. slight change structure for different sintered hours reflected in intensity samples. low temperature electron paramagnetic resonance (EPR) spectra PL decay curves are employed to probe into luminescence centers non-doped

Nowadays, one-phase and full-color phosphors have gained increasing interest. Here, we show that Mn-activated zinc gallogermanate, Zn1+xGa2-2xGexO4: Mn, x = 0 ~1, exhibit a broadly tunable luminescence from green to deep red with the substitution of Ga3+ by Ge4+. The emissions are attributed Mn2+ Mn4+ occupying tetrahedrally coordinated Zn2+ octahedrally sites, respectively. origin is discussed. present potential uses in field emission displays vivo bio-imaging.

Abstract An efficient Pd(II)‐catalyzed one‐pot tandem cyclization/alkylation reaction of internal alkynes has been reported. In this reaction, a wide range structurally diverse β /;‐isoxazole aldehydes/ketones could be obtained in good to excellent yields from various alkynyl oxime ethers and allylic or homoallylic alcohols. The gram‐scale experiment transformations the newly products demonstrated that method should general useful synthetic tool. magnified image

Cracks appeared in GaN epitaxial layers which were grown by a novel method combining metal organic vapor-phase epitaxy (MOCVD) and hydride (HVPE) one chamber. The origin of cracks 22-μm thick film was fully investigated high-resolution X-ray diffraction (XRD), micro-Raman spectra, scanning electron microscopy (SEM). Many under the surface first observed SEM after etching for 10 min. By investigating cross section sample with distribution stress along depth determined. From interface...

This study was aimed at improving oral bioavailbility and reducing the food effect of cinacalcet hydrochlorde (CINA), a poorly soluble drug for treatment chronic kidney disease, by preparing its nanocrystals (NCs) utilizing precipitation-ultrasonication method. Based on single factor method Box-Behnken design, with particle size polydispersity index (PDI) as indexes, optimal formulation achieved. It investigated that PDI NCs prepared basis were 244 ± 2 nm 0.168 0.001, respectively. The...

Abstract Plant‐derived nanovesicles (PDNVs) and extracellular vesicles (EVs) represent a promising area of research due to their unique properties potential therapeutic applications. Pinellia ternata (P. ternata) is well‐known for its pharmacological but the PDNVs EVs derived from it have been largely understudied. Previous studies shown that Temporary Immersion Bioreactor System (TIBS) plays an important role in controlling plant growth order obtain reproducible PDNVs. were isolated P....
