Self‐sustained actuators powered by natural, low‐energy sources based on liquid crystal elastomers (LCEs) are attractive as they offer high safety, abundant energy availability, and practicality in applications. However, achieving stable self‐sustaining motion with requires actuation strain rates within a narrow temperature range near ambient conditions—a great challenge LCEs low nematic‐to‐isotropic transition temperatures (Tni) generally exhibit reduced rates. To address this, we...
Patients with advanced non-small cell lung cancer (NSCLC) are prone to brain metastases (BM), which essentially include parenchymal (PM) and leptomeningeal (LM). We conducted a retrospective study comprehensively assess the clinical characteristics risk factors of patients NSCLC who develop PM LM. were enrolled. These then divided into three groups for analysis: without BM (No-BM), Data on each patient at time diagnosis extracted analyzed. In addition, prediction models developed evaluated A...
Although keratins are robust in nature, hydrogels producing their extracts exhibit poor mechanical properties due to the complicated composition and ineffective self-assembly. Here we report a bioinspired strategy fabricate keratin based on mechanism study through recombinant proteins. Homotypic heterotypic self-assembly of selected type I II different combinations was conducted identify crucial domain structures for process, kinetics, relationship with strength hydrogels. Segments best...
A LiCoO2 (LCO) cathode with LiBH4 modification (LBH-LCO) was obtained in a facile condition using fast wet-chemical synthesis method. X-ray photon spectroscopy analysis indicates that B3+ high oxygen affinity can quickly incorporate onto the LCO surface accompanied by Co3+ reduction. Meanwhile, XRD characterization shows modified samples have clear crystalline lamellar structure. After being LiBH4, LBH-LCO present increased cycling stability [with near 95%/85% capacity retention at 1 C/5 C...
The verifications of the calculated harmonic impedances are necessary for impedance estimation. Among existing methods verifications, method, by matching background voltage with measured when customer is out operation, widely used. harmonics can be based on IEC61000-3-6 (named as IEC method) or superposition index. However, some researchers ignore fact that these two cannot chosen arbitrarily, otherwise, misjudgments may occur. In our study, nonlinear customers classified into categories...
With the growing scale of wind farms and development grid connected technology, power quality problem has attracted more attention. Generally speaking, are mostly located in remote areas China, featuring weak connection structure long outgoing lines. The transformer leakage inductance, line reactance distributed capacitance may cause harmonic resonance, which not only deteriorates electric quality, but also endangers system stability. For example, LCL filter resistance burned accident was...
In order to control the FePO 4 particles size, reaction precipitation between Fe (NO 3 ) and H PO was performed by controlled crystallization technique. The influences of feed concentration, stirring speed temperature on agglomeration size were investigated. produced amorphous can be crystallied pure phase after calcining at 550 °C for 5 hours. agglomerates morphology characterized laser granulometer scanning electron microscope, respectively. results showed that products spherical...
Electrolyte of LiPF6-ethylene carbonate (EC)-methyl acetate (MA) was prepared. 1 M LiPF6-EC-MA electrolyte presented the conductivity in excess mS cm-1 at -50 oC. The cyclic voltammetry showed that better than conventional (EC)-diethyl (DEC) for formation SEI film. much cycleability LiPF6-EC-DE·C LiCoO2/Li cell. It is a promising alternative Li-ion batteries.
The Li/S polymer secondary batteries presents higher capacity, lower materials cost and much better performance in operation temperature. A nano-scale sulfur composite cathode material has been developed for these batteries, its cycle capacity is over 700mAh/g when the lithium metal used as anode; Cu/Sn alloy powder synthesized by a novel micro-emulsion process, 300 mAh/g; of PVdF gel electrolyte improved through addition nanometer SiO2 in-situ. advanced will be promising alternative next...
A novel process was proposed for preparing spinel LiMn2O4 with spherical particles from cheap materials of MnSO4, NaOH, NH3•H2O and LiOH. Its successful preparation started a carefully controlled crystallization Mn3O4, leading to the shape its high tap density. The mixture Mn3O4 LiOH sintered produce particle size retention. were excellent fluidity dispersivity, had density as 2.14 g cm-3 initial discharge capacity reaching 128 mAh g-1. 15th cycle kept be 125
Spherical LiNi0.8Co0.2O2 powders with particle size of 8~10μm were prepared based on controlled crystallization, and coated Al2O3 by Al(OH)3 sol, that was from Al(NO3)3 NaOH, at first time. SEM, XRD surface element analysis showed the nano-sized uniformly powder. At 25 °C, initial discharge capacity decreased 160 to 149 mAh g-1 after coating Al2O3. The 168 163 Al2O 55 °C. After Al2O3, retentions increased 83.8% 92.6% 50th cycle 25°C, 36.3% 90.8% 10th 55°C. This paves effective way improve...
Preparation and performance of poly(acrylonitrile-methylmethacrylate) based microporous gel electrolyte for Li-ion batteries were studied. The poly(acrylonitrile-methyl methacrylate (P(AMMA)) was synthesized by suspension polymerization, methacrylate) polymer membrane with 0.03~0.1mm prepared phase inversion technique. obtained putting the P(AMMA) in a liquid electrolyte, which solution 1.0 M LiPF6 dissolved 1:1 (v/v) mixture ethylene carbonate (EC) diethylene (DEC, heated at 60°C 2 hours....
