Surface Properties of p‐GaN and Formation of Nickel Metal Contacts

open access: yesAdvanced Materials Interfaces, EarlyView.
The amount of C, O, and Mg–O bonds on the surface of p‐GaN can be reduced while still maintaining the surface morphology by potassium hydroxide (KOH) wet chemical treatment. Heating this surface with Ni on top in ultra‐high vacuum (UHV) results in a crystalline Ga‐Ni alloy and diffusion of Ga, which creates vacancies close to valence band leading to ...

Well‐Defined Poly(HPMAm) Brushes via Surface‐Initiated RAFT Polymerization; A Mixed‐Chain Transfer Agent (CTA) Approach

open access: yesAdvanced Materials Interfaces, EarlyView.
A simple method relying on surface‐initiated RAFT polymerization is presented using a mixed‐chain transfer agent (mixed‐CTA) approach to grow well‐defined poly(HPMAm) brushes with precise control, achieving >70 nm thickness in 4 h at moderate temperature, 50 °C. Abstract Over three decades, efforts to prevent non‐specific protein adsorption on surfaces

An Atomic‐Scale View at γ’‐Fe4N as Hydrogen Barrier Material

open access: yesAdvanced Materials Interfaces, EarlyView.
This study demonstrates the efficacy of γ’‐Fe4N nitride layers, formed via gas nitriding, as hydrogen permeation barriers. Advanced characterization, hydrogen permeation analysis, and DFT calculations reveal a 20 fold reduction in hydrogen diffusion at room temperature.

Direct Seawater Electrolysis with Stabilized High‐Performance NiCr Anodes

open access: yesAdvanced Materials Interfaces, EarlyView.
An assembly combining a highly active NiFe layered double hydroxyde electrocatalyst and a NiCr foam anode shows high corrosion resistance during alkaline seawater electrolysis (ASE), minimal Cr leaching in the electrolyte, and long‐term efficiency. An electrolyzer comprising the so‐prepared anode and a cathode derivatized with NiMoO4 achieves overall ...
