Self‐Assembled Telecom Color Centers in Silicon and Their Growth Environment

Advanced Physics Research, EarlyView.
Influence of the growth pressure during the formation of self‐assembled color centers in silicon grown by molecular beam epitaxy at ultra‐low temperatures on the color center's photoluminescence spectral signature. The growth pressure crucially determines color center selectivity, as evidenced by G‐centers, W‐centers, and T‐centers, matrix purity, and ...

Flammability of Facades Across Scales and International Standards

Fire and Materials, EarlyView.
ABSTRACT Facade fires are a rare but destructive hazard that can lead to the rapid spread of fire between the floors and fire compartments of a building. Today, there are at least 21 different national standards for facade fire tests in use around the world, which seek to categorize facades based on their flammability.

Observed Linkages Between Marine Heatwaves and Extreme Weather Over Land: A New Zealand Case Study

International Journal of Climatology, EarlyView.
Marine heatwaves consistently warm New Zealand's land surface, but rainfall impacts occur only when synoptic systems enable moisture transport. This 38‐year analysis shows MHWs act as thermodynamic background drivers of heat and conditional amplifiers of extreme rainfall events or droughts.

Skewness of Impinging Cooling Blockage Jet

Applied Sciences
Building upon our previous aerodynamic characterizations of skewed jets, this study extends the investigation to systematically evaluate their thermal performance. Turbulent air jets are produced by unilaterally supplying coolant and forcing it through a series of concave perforated blockages having varying relative inner diameters (Din/Dj = 3.0, 4.0 ...

Controlling the Center of Mass Motion of Levitated Particles Using Structured Wavefronts

Laser &Photonics Reviews, EarlyView.
Optically levitated particles have great potential for quantum‐enhanced sensing. Precise control of the trapping beam is crucial to improve the stability and confinement of these systems. Here, we study how structured wavefronts can be used to control the center‐of‐mass motion of levitated particles, enhancing trap stiffness and enabling stable ...
