Strongly-Coupled Dark Energy plus Warm dark matter (SCDEW) cosmologies admit the stationary presence of ∼1% of coupled-DM and DE, since inflationary reheating. Coupled-DM fluctuations therefore grow up to non-linearity even in the early radiative expansion. Such early non-linear stages are modelized here through the evolution of a top-hat density enhancement, reaching an early virial balance wh...

A four- to seven-fold enhancement of leaf hydraulic conductance by light has been reported in three temperate tree species. The enhancement occurs in the liquid-flow pathway between the petiole and the site of water evaporation. The enhancement occurs within 1 h, and dissipates in darkness over a period of 1 to 10 h depending on species. Here we report light-induced enhancement of leaf hydrauli...

We report on the fabrication of an enhancement mode p-GaN/AlN/GaN high electron mobility transistor with selective area sublimation under vacuum p-GaN cap layer. The GaN evaporation selectivity is demonstrated thin 2 nm AlN barrier Furthermore, regrowth AlGaN a major key to increase maximum drain current in transistors and enables co-integration depletion devices.

We elucidated the distance-dependent plasmonic effects on radiative transitions from an Eu(3+) ion-doped phosphor by varying the thickness of the dielectric spacer. Magnesium oxide prepared by electron-beam evaporation was chosen for the dielectric spacer. Spectral overlap between emission from Eu(3+) ions and the plasmon band of Ag nanoparticles led to improved luminescence intensity. This lum...

Numerical simulations are presented to examine the effect of the lee-side static stability on the spillover of orographic precipitation. The results show that the presence a cold-air pool in the lee of a mountain ridge greatly increases the precipitation spillover because the cold pool suppresses the lee-side downslope air motion that otherwise leads to a rapid evaporation of the precipitation....

Deep-ultraviolet surface-enhanced Raman scattering (UV-SERS) is a promising technique for bioimaging and detection because many biological molecules possess UV absorption lines leading to strongly resonant Raman scattering. Here, Al nanovoid substrates are developed by combining nanoimprint lithography of etched polymer/silica opal films with electron beam evaporation, to give a high-performanc...

Evaporation from porous structured surfaces is encountered in a variety of applications including electronics cooling, desalination, and solar energy generation. Of major interest the design thermal systems for such prediction heat mass transfer rates during evaporation these surfaces. The present study develops figure merit (FOM) that characterizes efficacy evaporative microstructured Geometri...
