- Mixed Protein/Hexane Adsorption Layers Formed at the Surface of Protein Solution Drops Surrounded by Hexane Vapor

The adsorption of protein molecules from aqueous solution is significantly enhanced in presence of hexane vapor. The thermodynamic model assumes a double layer adsorption at the surface consisting of a primary adsorption layer consisting of protein and hexane molecules while the secondary layer is formed essentially by hexane molecules adsorbed from the hexane vapor phase.
- Strategic Preparation of Efficient and Durable NiCo Alloy Supported N-Doped Porous Graphene as an Oxygen Evolution Electrocatalyst: A Theoretical and Experimental Investigation

NiCo bimetallic alloy nanoparticles supported on porous N-doped graphene (NiCo/pNGr (75:25)) shows improved water splitting reaction at low overpotential of 260 mV@10 mA cm–2. The catalytic activity is credited to the porosity of graphene, presence of doped-N and presence of active metal alloy. The effectual metal alloy-conducting support interaction has been studied using the density functional theory calculations.

Scanning transmission electron microscopy demonstrates the effect that adding fluoroethylene carbonate additive to traditional electrolyte ethylene carbonate/diethylene carbonate (EC/DEC) has on solid electrolyte interphase (SEI) morphology. In the first 5 cycles, the addition of FEC to the traditional electrolyte produces an SEI that is uniform and dense. Conversely, the electrochemical decomposition of EC/DEC electrolyte forms a porous, inhomogeneous SEI that exposes more Si nanoparticles to the electrolyte.
- Gel-Infused Slippery Surface with Enhanced Longevity and Thermally Controllable Sliding Properties
Geyunjian H. Zhu, Chi Zhang, Chao Wang and Nicole S. Zacharia

A gel-infused surface is demonstrated for the first time. It is shown that based on the thermally dependent properties of the gel the speed of water drops on this surface can be controlled from water pinning to water sliding with a range of temperatures. A gel-infused surface is shown to lose the infused material more slowly than an equivalent liquid infused surface.
- High-Performance Organic–Inorganic Hybrid Piezo-Nanogenerator via Interface Enhanced Polarization Effects for Self-Powered Electronic Systems

Version of Record online: 30 AUG 2016 | DOI: 10.1002/admi.201600492
A piezoelectric nanogenerator composed of nanofibers of P(VDF-TrFE) and BaTiO3 nanostructures is demonstrated using a conducting carbon cloth as the current collector. Filling of interfiber spaces with BaTiO3 nanostructures results in enhanced performance, suggesting a crucial role of the interface polarization. A maximum power output of 28 μW cm−2 is realized and the device can successfully charge a smart phone.
