Analysis of the Surface Dispersion in the Mediterranean Sub-Basins

open access: yesFrontiers in Marine Science, 2020
Surface dispersion properties give an immediate characterization of the spreading of passive and active tracers in the ocean, like pollutant and marine species.

Investigation of Zebrafish Embryo Membranes at Epiboly Stage through Electrorotation Technique

open access: yesMembranes, 2023
A preliminary exploration of the physiology and morphology of the zebrafish embryo (ZFE) during the late-blastula and early-gastrula stages through its electrical properties was performed, applying the electrorotation (ROT) technique.

Dynamic thermal radiation regulation for thermal management

open access: yesNext Energy, 2023
With the improvement of living standards, energy consumption for heating and cooling is increasing. Traditional heaters or coolers (air conditioners etc.) consume lots of energy and only transfer heat to different places on Earth, which increases the ...

Derivation of the Planck Spectrum for Relativistic Classical Scalar Radiation from Thermal Equilibrium in an Accelerating Frame [PDF]

open access: yes, 2010
The Planck spectrum of thermal scalar radiation is derived suggestively within classical physics by the use of an accelerating coordinate frame. The derivation has an analogue in Boltzmann's derivation of the Maxwell velocity distribution for thermal ...

Precise Model for Small-Body Thermal Radiation Pressure Acting on Spacecraft [PDF]

open access: yes, 2017
A precise representation of small-body surface thermal radiation pressure effects acting on orbiting spacecraft is discussed. The proposed framework takes advantage of a general Fourier series expansion to compute small-body surface thermal radiation ...

Seawater Splitting for Hydrogen Generation Using Zirconium and Its Niobium Alloy under Gamma Radiation

open access: yesMolecules, 2022
Hydrogen production is produced for future green energy. The radiation–chemical yield for seawater without a catalyst, with Zr, and with Zr1%Nb (Zr = 99% Nb = 1%) were (G(H2) = 0.81, 307.1, and 437.4 molecules/100 eV, respectively.

Effect of Surface Microstructure on the Heat Dissipation Performance of Heat Sinks Used in Electronic Devices

open access: yesMicromachines, 2021
Heat sinks are widely used in electronic devices with high heat flux. The design and build of microstructures on heat sinks has shown effectiveness in improving heat dissipation efficiency. In this paper, four kinds of treatment methods were used to make

Measuring space radiation shielding effectiveness

open access: yesEPJ Web of Conferences, 2017
Passive radiation shielding is one strategy to mitigate the problem of space radiation exposure. While space vehicles are constructed largely of aluminum, polyethylene has been demonstrated to have superior shielding characteristics for both galactic ...

Polarization of Thermal Emission from Aligned Dust Grains Under an Anisotropic Radiation Field [PDF]

open access: yes, 1999
If aspherical dust grains are immersed in an anisotropic radiation field, their temperature depends on the cross-sections projected in the direction of the anisotropy.It was shown that the temperature difference produces polarized thermal emission even ...
