Patients with HER2-positive (HER2+) metastatic breast cancer (MBC) have poor prognoses. Pyrotinib has shown promising antitumor activity in MBC to improve progression-free survival (PFS). However, findings based on real-world data analyze whether pyrotinib affects overall (OS) remain scarce.This study is an exploratory analysis of brain metastasis (BM) and the final update our preceding 168 patients HER2+ MBC. PFS, OS, tumor mutation burden (TMB), clinical benefit rate (CBR), response (ORR)...
Halide perovskites hold exceptional promise as cheap, low temperature solution-processed optoelectronic materials. Yet they are hindered by poor structural and chemical stability, rapidly degrading when exposed to moisture or air. We demonstrate a solution-phase method for infiltrating methylammonium lead bromide perovskite (CH3NH3PbBr3, MAPbBr3) into nanoporous GaN which preserved the green photoluminescence of after up 1 year storage under ambient conditions. Besides protective effect,...
Although the solid-state lighting industry has achieved huge successes in both red and blue part of visible spectrum during last 40 years, light-emitting diodes (LEDs) that emit green light consistently exhibit inferior efficiencies. Thanks to use down-conversion phosphors, white LEDs have been commercialised without using LEDs. However, efficiency problem still hinders many potential applications limits overall system efficiency. This review first attempts conclude comment on complex...
Current cubic zincblende III-Nitride epilayers grown on 3C-SiC/Si(001) substrates by metal-organic vapor-phase epitaxy contain a high density of stacking faults lying the {111} planes. A combination high-resolution scanning transmission electron microscopy and energy dispersive x-ray spectrometry is used to investigate effects alloy segregation around in III-nitride light-emitting structure, incorporating InGaN quantum wells an AlGaN blocking layer. It found that vicinity faults, indium...
Growing green and amber emitting InGaN/GaN quantum wells in the zincblende, rather than wurtzite, crystal phase has potential to improve efficiency. However, optimization of emission efficiency these heterostructures is still required compete with more conventional alternatives. Photoluminescence time decays were used assess how well width number affect recombination rates, temperature dependent photoluminescence was determine factors affecting The radiative lifetime found be approximately...
Zincblende GaN has the potential to bridge “green gap” due absence of internal electric fields with respect wurtzite GaN. However, at present, quality zincblende light emitting diodes (LEDs) is not yet sufficient for useful efficient green devices. One major challenges poor spectral purity emitted light. A multimicroscopy approach, combining scanning electron microscopy-cathodoluminescence (SEM-CL), transmission microscopy (STEM), and diffraction (SED), applied on a single feature enable...
Zincblende InGaN/GaN quantum wells offer a potential improvement to the efficiency of green light emission by removing strong electric fields present in similar structures. However, high density stacking faults may have an impact on recombination these systems. In this work, scanning transmission electron microscopy and energy-dispersive x-ray measurements demonstrate that one-dimensional nanostructures form due indium segregation adjacent faults. photoluminescence experiments, structures...
Abstract The microstructure of green-emitting InGaN/GaN quantum well (QW) samples grown at different temperatures was studied using cross-section scanning transmission electron microscopy (STEM) and plan-view cathodoluminescence (CL). sample with the lowest InGaN growth temperature exhibits microscale variations in CL intensity across surface. Using STEM analysis such areas, observed darker patches do not correspond to any observable extended defect. Instead, they are related changes extent...
