- Reducing the In2O3(111) Surface Results in Ordered Indium Adatoms
Margareta Wagner, Steffen Seiler, Bernd Meyer, Lynn A. Boatner, Michael Schmid and Ulrike Diebold

When the In2O3 surface is subjected to reducing conditions it responds with the formation of an ordered array of isolated In adatoms. The facile back-and-forth between the oxidized and reduced surface should allow tuning surface properties in a judicious and clear-cut manner. On a more fundamental level, the ordered adatom structure is an entirely novel way of any oxide surface to respond to reducing conditions.
- The Effect of Thermal Reduction on the Water Vapor Permeation in Graphene Oxide Membranes

The thermal reduction of graphene oxide membranes results in a scalable behaviour of the water vapor transmission rate. The phenomenological contradiction between this behavior and the observed progressive structural alteration is ascribed to water intercalation within the galleries of the low-dimensional carbon nanostructures. The experimental results are in accordance with those from the recently published first principle calculations.
- Origin of Work Function Modification by Ionic and Amine-Based Interface Layers
Stephan van Reenen, Sandra Kouijzer, René A. J. Janssen, Martijn M. Wienk and Martijn Kemerink

Work function modification by interlayers based on tertiary aliphatic amines and polyelectrolytes is found to follow a general mechanism. When deposited on conductors and semiconductors an interfacial dipole forms, induced by image charges in the substrate. The size and movability of the charged constituents forming the dipole determines the dipole strength and direction.
- “Smart” Surface Capsules for Delivery Devices
Ekaterina V. Skorb and Helmuth Möhwald
Article first published online: 29 JUL 2014 | DOI: 10.1002/admi.201400237
This review describes emerging trends and future challenges for designing next generation of responsive “smart” surface capsules. Surface capsules can be adapted for biomedical applications, lab-on-chip, organ-on-chip, attractive self-healing anticorrosion and antifouling prospects. Understanding the underlying mechanisms of capsule opening by different stimuli is essential for developing new methods of encapsulation, release, and targeting.
- Trapping Light with a Nanostructured CeOx/Al Back Electrode for High-Performance Polymer Solar Cells
Zhan'ao Tan, Liangjie Li, Cong Li, Li Yan, Fuzhi Wang, Jia Xu, Lu Yu, Bo Song, Jianhui Hou and Yongfang Li
Article first published online: 29 JUL 2014 | DOI: 10.1002/admi.201400197
A simple and effective approach is demonstrated to construct a nanostructured back electrode from CeOx suspended solution for efficient light trapping within the PSCs. The enhanced light trapping and electron-collecting CeOx/Al cathode shows general suitability for the normally used photoactive layer of P3HT:PCBM, P3HT:ICBA, and PBDTBDD:PCBM, resulting in significant enhancement in Jsc and Voc, thus leading to improvements in PCE.
