A chip-scale integrated cavity-electro-optomechanics platform [PDF]

, 2011
We present an integrated optomechanical and electromechanical nanocavity, in which a common mechanical degree of freedom is coupled to an ultrahigh-Q photonic crystal defect cavity and an electrical circuit.

Engineering Porous Hollow Metal‐Poly(Heptazine Imide) Spheres: An Optimized Synthetic Strategy for Controlling Surface, Morphology, and Properties

Advanced Functional Materials, EarlyView.
Hollow poly(heptazine imide) spheres are prepared through a novel approach that integrates hard templating with ionothermal synthesis. This method enables precise control over surface area, pore volume, hydrophilicity, light absorption, band position, and metal composition. These tunable properties facilitate the customized design of semiconductors for

Immersion Cooling of Electronics in DoD Installations: [PDF]

, 2016
A considerable amount of energy is consumed to cool electronic equipment in data centers. A method for substantially reducing the energy needed for this cooling was demonstrated. The method involves immersing electronic equipment in a non-conductive liquid that changes phase from a liquid to a gas. The liquid used was 3M Novec 649.

The Influence of Annealing on the Sb Layer in the Synthesis of [001]‐Oriented Sb2Se3 Film for Photoelectrochemical Hydrogen Gas Generation

Advanced Functional Materials, EarlyView.
[001]‐oriented Sb2Se3 film with improved crystallinity and adjusted composition is achieved via a new thermal treatment approach consisting of preliminary annealing of the Sb layer before its selenization. The findings of this work demonstrate enhanced charge carriers' transportation, a stable performance, and an improvement of H2 generation from ...

Thermal management of automotive SiC-based on-board inverter with 500 W/cm2 in heat flux, and Two-phase immersion cooling by breathing phenomenon spontaneously induced by lotus porous copper jointed onto a grooved heat transfer surface

Journal of Thermal Science and Technology, 2020
In this study, we quantitatively discuss several kinds of thermal resistances that rise up to the surface in thermal management of automotive SiC-based on-board inverters with extremely high heat flux of 500 W/cm2. It is proven that a stacking structure

Prethermalization in the cooling dynamics of an impurity in a BEC

, 2017
We discuss the cooling dynamics of heavy impurity atoms in a Bose-Einstein condensate (BEC) by emission of Cherenkov phonons from scattering with the condensate.

Effect of electro discharge machining (EDM) on the AISI316L SS white layer microstructure and corrosion resistance [PDF]

, 2012
The localised corrosion resistance of austenitic stainless steels is strongly influenced by the quality of finished surface. EDM machining induces substantial changes by the high thermal gradients generated by electric sparks.

Immersing cooling of large spherical produces: Thermal parameters

International Journal of Energy Research, 1996
This article presents a combined experimental and modelling study for determining the thermal parameters of spherical produces in immersing cooling. In experiments, large spherically shaped water melons were selected as test samples, and cooled in water at surrounding temperatures of 0.5°C, 1.0°C, and 1.5°C.

Near‐Infrared Emitting Lanthanide Catecholate Giant Single Crystals – Morphology Control and Photon Down‐Conversion

Advanced Functional Materials, EarlyView.
Controlled syntheses of lanthanide coordination polymers based on the dihydroxybenzoquinone (DHBQ) organic linker afforded large single crystals of Ln‐DHBQ CPs (Ln = Yb, Nd). A novel structural variant of Yb‐DHBQ is identified by means of single crystal diffraction analysis.
