A luminescence ferroelectric oxide, Na0.5Bi2.5Nb2O9 (NBN), system with bismuth layer structure introduced by lanthanide ion (Er3+) has been demonstrated to exhibit reversible, high-contrast modulation (95%) and excellent fatigue resistance based on visible-light-driven photochromism (407 nm or sunlight). The coloration decoloration process can be effectively read out dual modes, upconversion downshifting, reversibly converted between green dark gray alternating visible light sunlight...

A solid-state composite polymer electrolyte comprising Li7La3Zr2O12 nanofibers (LLZO NFs) as fillers has the advantages of flexibility, ease processing, and being low cost, thus considered to be a promising material for use in next generation highly safe lithium metal batteries. However, poor compatibility organic parts inorganic materials leads quick capacity decay after long-term charge/discharging running because inorganic/organic interface deterioration thus, related ineffective...

Solid polymer electrolytes (SPEs) are considered to be attractive candidates for rechargeable batteries on account of their high safety and flexible processability. However, the restricted segmental dynamics limit Li+ conduction SPEs. Herein, a composite electrolyte membrane was prepared via in situ thermal-initiating polymerization diethylene glycol diacrylate (DEGDA) poly(vinylidene fluoride) frameworks (PVDF FMs) electrospun advance. As quasi-solid (QSPE), it provides multiple transport...

Poly(ethylene oxide) is a promising solid polymer electrolyte (SPE) matrix. However, its low ionic conductivity, narrow electrochemical window, and sluggish interfacial charge transfer limit use in solid-state batteries at room temperature. Herein, we report the situ polymerization of poly(2,2,3,4,4,4-hexafluorobutyl acrylate-copolymer-2-(2-(2-methoxyethoxy) ethoxy)ethyl acrylate) (P(HFBA-co-MEA)) with lithium bis(trifluoromethane sulfonamide) (LiTFSI) to form fluorinated SPE...

Abstract Decoupled electrolysis for hydrogen production with the aid of a redox mediator enables two half-reactions operating at different rates, time, and spaces, which offers great flexibility in operation. Herein, pre-protonated vanadium hexacyanoferrate (p-VHCF) is synthesized. It high reversible specific capacity up to 128 mAh g −1 long cycling performance 6000 cycles retention about 100% current density 10 A due enhanced bonding network. By using this mediator, membrane-free water...

A valence modulating strategy is approached to enhance the catalytic activity of Ni₃ZnC_0.7for expediting conversion polysulfides.

In order to explore the diffusion and regeneration of bio-oil in aged bitumen, waste cooking oil (WCO), wood (WWO) straw liquefied residue (SLRO) were selected this paper. According surface wetting theory, contact angle is obtained by combining laboratory experiments with molecular dynamics (MD) simulation, parameters are calculated evaluate behavior bio-oil. The experimental phenomena process main factors driving further analyzed. A permeation experiment designed obtain fusion layer (PFL)....

Temperature is vital in plant growth and agricultural fruit production. Litchi chinensis Sonn, commonly known as litchi, appreciated for its delicious fragrant blossoms susceptible to stress when exposed low temperatures. This study investigates the effect of two cryoprotectants that counteract cold during litchi flowering, identifies genes generate resistance induced by treatments, hypothesizes roles these resistance. Whole plants were treated with Bihu Liangli cryoprotectant solutions...

In order to study the high and low temperature properties, fatigue of silica fume/SBS (Styrene-Butadiene-Styrene) compound modified asphalt (SFSCMA), dynamic shear rheometer (DSR) bending beam (BBR) are used matrix (MA), fume (SFMA) (silica (SF) 6%), SBS (SBSMA) (mass ratio Matrix 4%), asphalt, rheological properties with different additions also studied. The modification mechanism SFSCMA was studied by scanning electron microscope (SEM). investigation results turn out: along increase in...

Abstract In order to accurately describe the self-healing behavior of recycled asphalt prepared by residue oil straw liquefaction (ROSL), five ROSL contents 2%, 4%, 6%, 10%, and 15% were added aged represent are denoted as ROSL-2, ROSL-4, ROSL-6, ROSL-10, ROSL-15, respectively. Molecular simulation was used simulate healing nano cracks. A three-layer system established in which two sides molecules middle is a 30 Å vacuum layer. The layer represented internal cracks asphalt. results show that...

A real rejuvenator must have the ability to disaggregate oxidized asphaltene nanoclusters. However, few studies pay attention topic, and there is a lack of comparison disaggregation different rejuvenators. Thus, regeneration mechanism three bio-rejuvenators (waste cooking oil (WCO), waste wood (WWO), straw liquefied residue (SLRO)) on nanoclusters were studied in this paper. Laboratory tests molecular dynamics (MD) simulation used compare effectiveness reveal its corresponding mechanism. It...

Conventional one-step water electrolyzers generate H2 accompanied by O2 evolution, and may cause gas mixing high cell voltage inputs.
