Carbazole‐Based Thin Microporous Polymer Films for Photocatalytic Hydrogen Evolution

open access: yesAdvanced Materials, EarlyView.
Photocatalytic hydrogen evolution with electropolymerized microporous films enable a direct and scalable process for the production of industrial relevant amounts of hydrogen gas. For developing cost‐ and material‐effective devices it is beneficial to increase the accessible outer surface area via microstructuring and stacking of polymeric films ...

Combining X‐Ray Photoelectron and Absorption Spectroscopies for Determining Surface Chemistry and Composition of Ti3C2Tx MXene

open access: yesAdvanced Materials Interfaces, EarlyView.
The surface chemistry and core composition of Ti3C2Tx MXenes is often derived from X‐ray Photoelectron Spectroscopy (XPS) but its determination and quantification remain difficult due to adsorbed species such as adventitious carbon. This challenge is overcome by using energy‐dependent XPS and depth profile modeling of the Ti3C2Tx MXene surface ...

The clinical utility and safety of biomarker-guided immunosuppression withdrawal in liver transplantation: the LIFT prospective RCT

open access: yesEfficacy and Mechanism Evaluation
Background Long-term surviving liver transplant recipients can spontaneously develop operational tolerance, which allows them to completely discontinue their immunosuppression, but we lack validated tools to predict the likelihood of rejection following ...

Ultrafast Electron Dynamics at the Water‐Modified InP(100) Surface

open access: yesAdvanced Materials Interfaces, EarlyView.
P‐rich indium phosphide is exposed to H2O at 200 °C, leading to water adsorption stabilized by hydroxyl groups. Time‐resolved two‐photon photoemission indicates an increase in electron lifetimes at the near‐surface conduction band minimum by at least an order of magnitude; this is correlated using Density‐functional theory to dampening of surface P ...
