The 0D–2D nucleation and growth mode is presented in molybdenum disulfide (MoS2) chemical vapor deposition synthesis. Partially sulfured molybdenum suboxide nucleation centers are demonstrated experimentally, followed by these centers being converted to MoS2 nanoparticles and MoS2 layer growth initiation from the nanoparticle edges. The work reveals the mechanism for MoS2 nucleation and growth.
- Polymeric Flaky Nanostructures from Cellulose Stearoyl Esters for Functional Surfaces
Yonggui Wang, Jia Tian, Xu Deng, Longquan Chen, Sabine Rosenfeldt, Stephan Förster, Philipp Vana and Kai Zhang

Polymeric flaky nanostructures (PFNS) as flakes of flower-like particles and surface patterns on diverse substrates are prepared from cellulose stearoyl esters via a novel temperature-induced process. These flaky nanostructures exhibit nonwetting properties against aqueous solutions and glycerol. Their fabrication process demonstrates a facile method for the construction of functional materials.
- Interface Modification by Simple Organic Salts Improves Performance of Planar Perovskite Solar Cells

Simple organic salts are used as a cheap alternative for hole-conducting materials in methylammonium lead bromide perovskite solar cells and obtaining power conversion efficiency of 4.4%. The findings suggest that the polar organic salts interact with the perovskite surface, leading to formation of a surface dipole or change of an existing one on the perovskites that changes its effective work function.
- Molecular Layer Deposition for Surface Modification of Lithium-Ion Battery Electrodes
Chunmei Ban and Steven M. George
Version of Record online: 21 OCT 2016 | DOI: 10.1002/admi.201600762
The molecular layer deposition (MLD) of organic-inorganic hybrid materials enables the synthesis of totally new materials families with versatile characteristics that are not possible by any other existing technique. The review discusses various MLD materials and their implementation to stabilize lithium-ion (Li-ion) electrodes and to accommodate the volumetric changes in high-capacity Li-ion electrodes.
- Orientation Control of Selected Organic Semiconductor Crystals Achieved by Monolayer Graphene Templates

It is reported that graphene template layers can adjust the orientation of selected organic molecules in thin films. Significant optical and electronic ramifications of directed growth are observed. The energy level shifts upon graphene templating show that n-type materials behave in an opposite manner to p-type materials, which is explained using calculated electrostatic potential energy surfaces.
