Bionic Artificial Leaves Based on AIE‐Active Supramolecular Hydrogel for Efficient Photocatalysis
Advanced Science, EarlyView.A novel bionic artificial leaf is developed by integrating host‐guest interactions with covalent bonding. Meso‐functionalized pillararene (m‐TPEWP5) formed a stable host‐guest complex HGSM with guest G, which is copolymerized with gelatin methacryloyl (GelMA) to form a hydrogel HGGelMA for encapsulating eosin Y (ESY).

Advanced Electronic Materials, EarlyView.The 70% single‐walled carbon nanotube (SWNT) / 30% poly(90aniline‐co‐10acrylonitrile) composite exhibited a 1.7‐fold improvement in thermoelectric power factor as compared to SWNT/polyaniline (PANI) prepared under identical conditions. This work demonstrates that wrapping SWNTs with copolymers comprising monomers of conducting and insulating polymers ...

Advanced Electronic Materials, EarlyView.This paper presented ZnO‐based crossbar RRAMs by electrohydrodynamic (EHD) printing technology under in‐space manufacture environment as microgravity (µG). The crossbar structures of Ag/ZnO/Ag are fabricated under earth with in‐space microgravity. With the microgravity effect, a significant electroforming forming voltage reduced 89.3% as a storage ...

Semi-analytical guidance algorithm for autonomous close approach to non-cooperative low-gravity targets [PDF]
, 2014 An adaptive guidance algorithm for close approach to and precision landing on uncooperative low-gravity objects (e.g. asteroids) is proposed. The trajectory, updated by means of a minimum fuel optimal control problem solving, is expressed in a polynomial

In Situ Observation of Post‐CO Intermediates to Decode C─C Coupling Pathways in CO2 Electroreduction
Angewandte Chemie, EarlyView.Resonance Raman spectroscopy (RRS) was used to observe the in situ CO2 electroreduction process by designing copper electrodes with unique structures. This dynamic observation allowed for the capture of the C─C coupling process, where CH2 asymmetrically couples with CO to form CH2CO.

Advanced Energy Materials, EarlyView.The decomposition of Nb‐substituted LLZO solid electrolytes is reported through a propagating reaction between Nb5+ dopants and the Li metal electrode. This work suggests dopants that segregate to interfaces/grain boundaries in LLZO will exhibit reactivity that can propagate into bulk and shed light on new mechanisms for the problematic role of oxygen ...
