TiO2-pattern-modulated actuation of Agarose@CNT/Agarose bilayer induced by light and humidity 10.1039/C8TA01967C 2018-04-11 A smart bilayer of AG@CNT/AG composed of carbon nanotubes (CNTs) and Agarose (AG) is developed. TiO2 pattern which partly reflects light is introduced at the bilayer surface, giving rise to a spatially-selective photothermal effect that can be used to induce ...
Flyweight and Superelastic Graphene Aerogel as High-capacity Adsorbent and Highly Sensitive Pressure Sensor 10.1039/C7TA11348J 2018-04-11 Preparation of ultralight, superelastic and multifunctional graphene aerogels still remains a challenge. Herein we develop a silane-crosslinked and modified graphene aerogels (SGA) using a novel and simple method of chemical vapor deposition of methyltriethox...
Co9S8@Carbon Porous Nanocages Derived from a Metal-Organic Framework: A Highly Efficient Bifunctional Catalyst for Aprotic Li-O2 Batteries 10.1039/C8TA01913D 2018-04-11 Discovering effective bifunctional catalysts to facilitate Li2O2 oxidation and prolong discharge life to ease batteries’ “sudden death” is a key task for developing high performance Li-O2 batteries. Herein, an advanced aprotic Li-O2 battery is designed using ...
High Dehumidification Performance of Amorphous Cellulose Composite Membranes prepared from Trimethylsilyl Cellulose 10.1039/C8TA00350E 2018-04-11 Cellulose is widely regarded as an environmentally friendly, natural and low cost material which can significantly contribute the sustainable economic growth. In this study, cellulose composite membranes were prepared via regeneration of trimethylsilyl cellul...
Heterogeneous NiS/NiO multi-shelled hollow microspheres with enhanced electrochemical performances for hybrid-type asymmetric supercapacitors 10.1039/C8TA01866A 2018-04-11 Heterogeneous structures with binary chemical compositions could achieve unique chemical properties by modification of the components and interface engineering. Meanwhile, hollow microspheres with complex interiors have been extensively studied in energy stor...
Tricomponent brookite/anatase TiO2/g-C3N4 heterojunction in mesoporous hollow microspheres for enhanced visible-light photocatalysis 10.1039/C8TA00386F 2018-04-11 The three major polymorphs of TiO2, anatase, rutile, and brookite, are widely utilised to form heterojunction semiconductors for superior photocatalytic performance due to their unique optical properties and tunable morphologies. Mesoporous brookite/anatase T...
Direct Observation of Cation-Exchange in Liquid-to-Solid Phase Transformation in FA1−xMAxPbI3 Based Perovskite Solar Cells 10.1039/C8TA01642A 2018-04-11 Mixed-organic-cation FA1-xMAxPbI3 perovskites are currently attracting intensive attention for their high photovoltaic performance. However, FA1-xMAxPbI3 usually has undesired non-perovskite phase leading to a compromised efficiency, and a facile strategy to ...
Supramolecular approach towards light-harvesting materials based on porphyrins and chlorophylls 10.1039/C7TA11274B 2018-04-11 Photosynthesis is one of the most important processes that supplies the energy required for the survival of all living things. The initial process is the absorption of sunlight by a supramolecular organization called a light-harvesting antenna. Sophisticated ...
Extremely low trap-state energy level perovskite solar cells passivated using NH2-POSS with improved efficiency and stability 10.1039/C7TA11345E 2018-04-11 Both efficiency and stability are two essential performance factors in hybrid halide perovskite solar cells, which are closely related to the ionic defects at the surface and grain boundary of the absorber films. To passivate these defects, we propose a deriv...
Research Progress on Vanadium-based Cathode Materials for Sodium Ion Batteries 10.1039/C8TA01627E 2018-04-11 Sodium ion batteries (SIBs) have attracted increasing attention as one of the most promising candidates for cost-effective, high-energy rechargeable batteries. Owing to their high theoretical capacity and energy density, and rich electrochemical interaction w...
