Stretchable supercapacitors (SSCs) are promising energy storage devices for emerging wearable electronics. However, the low-energy density and poor deformation performance still a challenge. Herein, an amphiphilic polyurethane-based organo/hydrogel electrolyte (APUGE) with H2O/AN-in-salt (H2O/AN-NaClO4) is prepared first time. The as-prepared APUGE shows wide voltage window (∼2.3 V), good adhesion, excellent resilience. In addition, intrinsically stretchable electrodes by coating activated...
We developed a fabrication method to achieve record-high thermal conductivity of 13.5 W m −1 K for electrically insulated polyethylene at coverage area 2.16 mm 2 .
Reaction of magnesium sulfate with aqueous ammonia in a hydrothermal condition (150−180 °C) produced fibrous hydroxide hydrate (MHSH) composition corresponding to stoichiometry 4.34Mg(OH)2·MgSO4·xH2O. Chemical analysis showed that the quantity x was more likely be 2 rather than well-known 3. The MHSH whiskers were about 0.3−2 μm diameter and 40−100 length, an aspect ratio no less 100. Selected area electron diffraction (SAED) X-ray patterns (XRD) well-crystallized orthorhombic structure. An...
The oxygen solubility in liquid silicon, both undoped and Sb-doped, equilibrium contact with SiO 2 has been analyzed after quenching by the SIMS (secondary ion mass spectroscopy) technique order to investigate influence of antimony addition on solubility. It shown that silicon melt increases from 2.08×10 18 2.29×10 atoms/cm 3 upon temperature 1447 1542°C. same range was twofold. Addition less than 1 at.% Sb caused practically no change solubility, while more 1.3 appreciably increased its...
The detailed temperature dependence of the surface tension molten silicon was measured using an accurate ring method. data obtained a SiC-coated graphite crucible showed approximately linear from 1,430° C to 1,650° C. Although in quartz glass similar above, maximum value about 20 dyn/cm smaller than that case SiC crucible. coefficient became positive at 1,425° and returned negative just above melring point. These results indicate melt flow near meniscus growing crystal tends be opposite crystal.
The surface layer of crystalline silicon implanted with 1.5 MeV Si ions doses ranging from 1×1011 to 1×1015 Si+/cm2 has been studied by Raman scattering. line intensities, shapes and shifts have used investigate the defects in near-surface layer. Above 1×1013 Si+/cm2, provides evidence for presence amorphous islands within structure. phonon-confinement model (PCM) which is based on breakdown wavevector selection rules due scattering finite domain sizes estimate effective average distance...
