Halide perovskites widely used solar cells, recently it that they also possess good properties. Different halide applied to memristors, including 3D organic–inorganic hybrid perovskites, 2D all‐inorganic cesium/rubidium lead lead‐less...

Vitrimer is a new class of polymeric materials which can be reprocessed to any shape while being permanently cross-linked. We designed and synthesized catalyst-free network with poly(dimethylsiloxane)etherimide (PDMS-NH2), terephthalaldehyde (TA), tri(2-aminoethyl)amine (TREA) through the condensation reaction between amino groups aldehyde groups. As result exchange dynamic imine bond obtained, this PDMS exhibits nature vitrimer-like material, examined by solubility stress-relaxation...

A programmable and biomimetic bilayer actuator enabled by a photo-liquefiable azobenzene derivative.

Abstract Controllable storage and release of solar energy has always been a highlighted scientific issue for its benefit mankind. Solar thermal fuels (STFs) supply closed cycle renewable energy‐storage strategy by transforming into chemical stored in the conformation molecular isomers, such as cis / trans ‐azobenzene, releasing it heat under various stimuli. Although potential high density STFs which are based on hybrids azobenzene derivatives carbon nanomaterials reported solvent‐assistant...

In this work, a simple but effective approach was proposed for preparing biodegradable plastic foams with high content of castor oil. First all, oil reacted maleic anhydride to produce maleated (MACO) without the aid any catalyst. Then were synthesized through free radical initiated copolymerization between MACO and diluent monomer styrene. With changes in MACO/St ratio species curing initiator, mechanical properties can be easily adjusted. way, biofoams comparable compressive stress at 25%...

Bimorph structure composing of photoresponsive LCP layer was designed to mimic plant's circadian rhythm behaviors.

Stimuli-responsive supramolecular organogels are fascinating for their dynamically controllable features, but it is difficult most versatile linear vinyl polymers to construct suitable cross-linking points in oils or organic solvents. Here, a mesomorphic organogelator was fabricated by self-assembly of one azopyridine-containing polymer and oleic acid the first time. Particularly, acts as not only important component mesogenic gelator also solvent entrapped interstices physically...

Abstract Since the breakthrough in power conversion efficiency when perovskite materials are used planer‐type solar cells, researchers have tried to apply into fiber‐shaped cells order achieve higher efficiency. However, difficulty of film fabrication on fiber surface makes it difficult obtain a high‐quality layer, and large improvement performance. In this work, vapor‐assisted deposition method is creatively applied preparation realizing purpose growing layer substrate after some innovative...

Soft actuators designed from stimuli-responsive polymers often possess a certain amount of bionic functionality because their versatile deformation. Liquid-crystalline (LCPs) and composites are among the most fascinating materials for soft due to great advantages flexible structure design easy regulation. In this Spotlight on Applications, we mainly focus our group's latest research progress in based LCPs composites. Some representative findings other groups also included better...

Phase transition materials can be utilized in a variety of functionalization scenarios, benefiting from the photoinduced changes their physicochemical properties. Among them, small molecular crystals or liquid-crystalline polymers containing azobenzene moieties that show phototunable melting points glass temperatures, respectively, have proven to significant optically controlled functional materials. In recent years, they been successfully used reversible mechanical actuation, adhesion,...

A probabilistic function (integrated source contribution function, ISCF) based on backward air mass trajectory calculation was developed to track sources and atmospheric pathways of polycyclic aromatic hydrocarbons (PAHs) the Canadian High Arctic station Alert. In addition movement masses, emission intensities at major processes partition, indirect photolysis, deposition occurring way were incorporated into ISCF. The predicted temporal trend PAHs Alert validated by measured PAH...

Abstract. The East China Sea (ECS) and the South (SCS) are two major marginal seas of North Pacific with distinct seasonal variations primary productivity. Based upon field observations covering both ECS northern SCS (NSCS) during December 2008–January 2009, we examined southward long-range transport nutrients from to northeastern (NESCS) carried by Coastal Current (CCC) driven prevailing northeast monsoon in wintertime. These escaped shelf, where production (PP) was limited winter, might...
