Investigation of the magnetic and transport properties single-walled small-diameter carbon nanotubes embedded in a zeolite matrix revealed that at temperatures below 20 kelvin, 4 angstrom tubes exhibit superconducting behavior manifest as an anisotropic Meissner effect, with gap fluctuation supercurrent. The measured characteristics display smooth temperature variations owing to one-dimensional fluctuations, mean-field transition 15 kelvin. Statistical mechanic calculations based on...
One of the major obstacles for polyhydroxybutyrate (PHB), a biodegradable and biocompatible polymer, in commercial applications is its poor elongation at break (~3%). In this study, effects nanocellulose contents their types, including cellulose nanocrystals (CNCs) nanofibers (CNFs) on crystallization, thermal, mechanical properties PHB composites were systematically compared. We explored toughening mechanisms by adding CNCs CNFs. The results showed that when morphology bagasse was rod-like...
We report a novel form of planar magnetic colloidal crystals formed by coated microspheres floating on liquid meniscus. Under an external field, the balance between repulsive interaction and "attractive" interaction, due to weight particles projected along surface tangent, yields not only triangular lattice with variable constant, but also all other crystal symmetries such as oblique, centered-rectangular, rectangular, square lattices. By using two different sized particles, local formations...
Abstract Background Tuina therapy (Tuina) is commonly utilized for managing knee osteoarthritis (KOA), yet the available evidence limited. This study aimed to evaluate effectiveness of compared widely accepted manual physical (mPT) patients with KOA. Methods Between Oct 2019 and 2021, KOA (Kellgren-Lawrence score II or III) were randomly assigned in a 1:1 ratio receive mPT, eight 20-min sessions over 3 weeks. Assessments performed at baseline, week 4, 8, 16. The primary outcome was change...
A novel approach for the preparation of interconnected macroporous polymers with a controllable pore structure was reported. The method based on polymerization water-in-oil Pickering high internal phase emulsion (HIPE) stabilized by polystyrene (PS)/silica composite particles. stabilizers were facilely obtained mixing positively charged PS microspheres and negatively silica nanoparticles, their amphiphilicity could be delicately tailored varying ratio silica. droplet size HIPEs characterized...
Through loading of TiO2 on the surface K6SiW11O39Co(II)(H2O)·xH2O (SiW11Co), a novel photoanode material has been created for dye-sensitized solar cells (DSSC). The absorbing band as well photoelectricity response range TiO2@SiW11Co is extended to visible range. In addition, absorption in UV enhanced notably compared with P25 (raw TiO2). More importantly, recombination network avoided. mixed powder (wt ∼1 : 1) assemble (N719) cells, which exhibit short-circuit photocurrent density high 18.05...
Elastocaloric refrigeration requires refrigerants with a good heat transfer ability and high fatigue life. A million-level life can be normally obtained for NiTi via compressive loading. However, existing compression-based elastocaloric prototypes only focus on tube refrigerants, no research has been reported the cross-sectional geometry design its influence compression behavior of refrigerants. Here, we propose tubular hole-type, fin-type, layer-type cross sections compare their tubes same...
Microcapsules with excellent barrier property are fabricated by Pickering emulsion templating stabilized using relatively lipophilic GO nanosheets to achieve good dispersion of in polymer shells.
Abstract Galloylated flavan-3-ols are key quality and health-related compounds in tea plants of Camellia section Thea. ptilophylla sinensis two representative species known for their high levels galloylated flavan-3-ols. Building on our knowledge galloyl catechin biosynthesis C. sinensis, we now focus the phenolics ptilophylla, aiming to elucidate mechanisms underlying accumulation these species. The phenolic were identified quantified using chromatographic colorimetric methods. Genes...
