Energy and water vapor transport across a simplified cloud-clear air interface [PDF]

open access: yesJournal of Physics: Conference Series, 2014
We consider a simplified physics of the could interface where condensation, evaporation and radiation are neglected and momentum, thermal energy and water vapor transport is represented in terms of the Boussinesq model coupled to a passive scalar ...

Energy-Efficient Liquid Crystal Smart Window with a Clear View

open access: yesCrystals, 2023
In this study, we enhance the angular-selective light absorption capabilities of guest–host liquid crystal (GHLC) cells by introducing a novel design featuring a uniform lying helix (ULH) structure. Previously GHLC cells, predominantly vertically aligned

Carrier Dynamics of Efficient Triplet Harvesting in AgBiS2/Pentacene Singlet Fission Solar Cells

open access: yesAdvanced Science, 2023
Singlet fission is a process by which an organic semiconductor is able to generate two triplet excitons from a single photon. If charges from the triplets can be successfully harvested without heavy losses in energy, then this process can enable a single‐

Photonic microstructures for energy-generating clear glass and net-zero energy buildings [PDF]

open access: yesScientific Reports, 2016
AbstractTransparent energy-harvesting windows are emerging as practical building-integrated photovoltaics (BIPV), capable of generating electricity while simultaneously reducing heating and cooling demands. By incorporating spectrally-selective diffraction gratings as light deflecting structures of high visible transparency into lamination interlayers ...

Removal of Fe impurities from Al alloy scraps by electromagnetic directional solidification combined with Si addition

open access: yesJournal of Materials Research and Technology, 2023
The removal of Fe from Al alloy scraps is the main challenge for their recycling because the excess of Fe usually forms needle-like phases in the Al alloys, which reduces their mechanical properties.

Conversion mechanism of NiCo2Se4 nanotube sphere anodes for potassium-ion batteries

open access: yesEnergy Materials and Devices, 2023
Given the abundance of potassium resources, potassium-ion batteries are considered a low-cost alternative to lithium-ion types. However, their electrochemical performance remains rather unsatisfactory because potassium ions have sluggish kinetics and ...
