Flexible graphene polyimide nanocomposites (0.1–4 wt %) with superior mechanical properties over those of neat resin have been prepared by solution blending. Imide moieties were grafted to amine-functionalized using a step-by-step condensation and thermal imidization method. The imide-functionalized exhibited excellent compatibility N-methyl-2-pyrrolidone. dynamic storage moduli the increased linearly increasing content for both unmodified imidized graphene. Moduli 25–30% higher than...
Thin-film anodes for Li-ion batteries prepared by using electrostatic spray deposition are reported. They consist of a tin-based amorphous oxide composite with porous, spherical, multideck-cage morphology (see figure). The electrochemical properties the thin-film electrodes shown to be improved significantly introducing Li2O and CuO, ternary Li2O–CuO–SnO2 electrode being demonstrated exhibit best performance. Supporting information this article is available on WWW under...
Abstract The spatial distribution and transport characteristics of lithium ions (Li + ) in the electrochemical interface region a anode ion battery directly determine Li deposition behavior. regulation solvation sheath on solid electrolyte interphase (SEI) by chemistry is key but challenging. Here, 1 m trifluoroacetate (LiTFA) induced to regulate sheath, which significantly suppresses dendrite formation enables high Coulombic efficiency 98.8% over 500 cycles. With its strong coordination...
Abstract Layered transition metal sulfides (LTMSs) have tremendous commercial potential in anode materials for sodium‐ion batteries (SIBs) large‐scale energy storage application. However, it is a great challenge most LTMS electrodes to long cycling life and high‐rate capability due their larger volume expansion the formation of soluble polysulfide intermediates caused by conversion reaction. Herein, layered CuS microspheres with tunable interlayer space pore volumes are reported through...
Abstract Sluggish evolution of lithium ions’ solvation sheath induces large charge‐transfer barriers and high ion diffusion through the passivation layer, resulting in undesirable dendrite formation capacity loss batteries, especially at low temperatures. Here, an ion‐dipole strategy by regulating fluorination degree solvating agents is proposed to accelerate Li + sheath. Ethylene carbonate (EC)‐based fluorinated derivatives, fluoroethylene (FEC) di‐fluoro ethylene (DFEC) are used as for a...
Abstract Oxygen evolution reaction (OER) is an obstacle to the electrocatalytic water splitting due its unique four‐proton‐and‐electron‐transfer process. Many methods, such as engineering heterostructure and introducing oxygen vacancy, have been used improve catalytic performance of electrocatalysts for OER. Herein, above two kinds regulation are simultaneously realized in a catalyst by using ion irradiation technology. A nanosheet structured NiO/NiFe 2 O 4 with rich vacancies converted from...
Abstract Lithium–sulfur (Li–S) batteries, with high theoretical energy density, promise to be the optimal candidate of next‐generation energy‐storage. Rapid development in materials has made a major step forward Li–S batteries. However, big gap cycle life and efficiency for practical applications still remains. Reasonable design materials/electrodes is significant aspect that must addressed. The rising metal‐organic frameworks (MOFs) are new class crystalline porous organic–inorganic hybrid...
High switching temperature shape memory polymers (SMPs) were developed from metal salts of sulfonated PEEK (M-SPEEK) ionomer and composites the M-SPEEK ionomers a fatty acid salt. The neat exhibited reasonable behavior, but composite SMPs showed very promising behavior. prepared 70 wt % (M = sodium or zinc) 30 oleate (NaOl). Ionic nanodomains formed by interactions ionic groups provided permanent physically cross-linked network, strong dipolar between dispersed phase crystalline NaOl...

Abstract Self-assembled nanostructure arrays integrating the advantages of intrinsic characters as well array stability are appealing in advanced materials. However, precise bottom-up synthesis without templates or substrates is quite challenging because general occurrence homogeneous nucleation and difficult manipulation noncovalent interactions. Herein, we first report precisely manipulated well-defined louver-like P-doped carbon nitride nanowire (L-PCN) via a supramolecular self-assembly...
It is of importance but highly challenging for copper (Cu)-based catalysts to maintain the structure active Cu sites under working conditions. Herein, commercial Cu/ZnO/Al2O3 catalyst was confined in mesoporous SiO2–Al2O3 shell via hydrothermal synthesis (CZAS@SA) selective hydrogenation CO2 dimethyl ether (DME) and methanol. CZAS@SA exhibited higher intrinsic activity formation DME methanol much lower CO than Cu/ZnO/Al2O3. Thus, total selectivity enhanced from 9.1 63.3 mol %. In situ X-ray...
Polarity dependence of the gate tunneling current in dual-gate CMOSFETs is studied over a oxide range 2-6 nm. It shown that, when measured accumulation, I/sub g/ versus V/sub characteristics for p/sup +//pMOSFET are essentially identical to those n/sup +//nMOSFET; however, inversion, exhibits much lower same |V/sub g/|. This polarity explained by difference supply electrons. The carrier transport processes biased inversion discussed detail. Three considered: (1) valence band hole from Si...
