Al₂O₃‐Functionalized Carbon Nanomembranes with Enhanced Water Permeance and Selectivity for Efficient Air Dehumidification

open access: yesAdvanced Functional Materials, EarlyView.
Carbon nanomembranes with ultra‐thin Al2O3 functionalization are less than 15 nm thin and exhibit outstanding permeation performance with a water vapor/nitrogen selectivity higher than 1 × 104, twice that of pristine CNMs, and an exceptionally high water vapor permeation rate for potential applications in air dehumidification.

Cost-aware Portfolios in a Large Universe of Assets [PDF]

open access: yesarXiv
This paper considers the finite horizon portfolio rebalancing problem in terms of mean-variance optimization, where decisions are made based on current information on asset returns and transaction costs. The study's novelty is that the transaction costs are integrated within the optimization problem in a high-dimensional portfolio setting where the ...

Analyzing Electronic Excitations and Exciton Binding Energies in Y6 Films

open access: yesAdvanced Functional Materials, EarlyView.
The Y6 molecule is used for increasing the efficiency of organic solar cells. The exciton binding energy is calculated for ensembles of Y6 molecules that are representative of the typically used films. The calculations show that the excitons typically spread out over many molecules.
