Role of dislocations in nitride laser diodes with different indium content
Scientific Reports, 2021 In this work we investigate the role of threading dislocations in nitride light emitters with different indium composition. We compare the properties of laser diodes grown on the low defect density GaN substrate with their counterparts grown on sapphire ...

Molecules, 2021 Stable, oil-in-water nanoemulsions containing astaxanthin (AsX) were produced by intense fluid shear forces resulting from pumping a coarse reagent emulsion through a self-throttling annular gap valve at 300 MPa.

Bidirectional light-emitting diode as a visible light source driven by alternating current
Nature Communications, 2023 Gallium nitride-based light-emitting diodes have revolutionized the lighting market by becoming the most energy-efficient light sources. However, the power grid, in example electricity delivery system, is built based on alternating current, which raises ...

Plasmons in AlGaN/GaN grating-gate structure probing with 300 K background illumination
AIP Advances, 2023 We show that terahertz plasmons in AlGaN/GaN grating-gate structures efficiently modulate the reflection of room temperature thermal radiation, leading to spectra that are in agreement with the measurements of plasmon absorption using high-power external

Plant responses to rising vapor pressure deficit.
New Phytologist, 2020 Recent decades have been characterized by increasing temperatures worldwide, resulting in an exponential climb in vapor pressure deficit (VPD). VPD has been identified as an increasingly important driver of plant functioning in terrestrial biomes ...

Hidden fluid mechanics: Learning velocity and pressure fields from flow visualizations
Science, 2020 Machine-learning fluid flow Quantifying fluid flow is relevant to disciplines ranging from geophysics to medicine. Flow can be experimentally visualized using, for example, smoke or contrast agents, but extracting velocity and pressure fields from this ...

The impact of point defects in n-type GaN layers on thermal decomposition of InGaN/GaN QWs
Scientific Reports, 2021 The aim of this paper is to give an experimental evidence that point defects (most probably gallium vacancies) induce decomposition of InGaN quantum wells (QWs) at high temperatures.

Journal of Financial Economics, 2014 We study price pressures, i.e., deviations from the efficient price due to risk-averse intermediaries supplying liquidity to asynchronously arriving investors. Empirically, New York Stock Exchange intermediary data reveals economically large price pressures, 0.49% on average with a half life of 0.92 days. Theoretically, a simple dynamic inventory model
