Abstract:
... In this article, the breaking elongation properties of woven fabrics with incorporated PBT yarns are presented. Different polybutylene terephthalate (PBT) yarns (multifilament PBT yarn, cotton core yarn and twisted viscose yarn, both with PBT in the core) were used. Textured PBT yarns have latent elastic properties, which become visible after the thermal treatment by the finishing process. The aim ...

Abstract:
... The effect of Hf and Ta on the microstructure of powder metallurgy Ni-based superalloys after heat treatment was investigated. Hf and Ta change the distribution and main components of MC carbides, inhibiting TiC carbides precipitate along prior particle boundaries by forming stable Hf- and Ta-rich carbides inside powders during the process of hot isostatic pressing. The partition of Hf and Ta in γ ...

Abstract:
... Layered vanadium-based metal oxides were regarded as promising cathode materials accounting for suitable K⁺ transport channels as well as high work potential in K-ion batteries. Nevertheless, because of the large radius of K⁺ and the rigid structure of inorganic materials, the typical K₀.₄₈₆V₂O₅ suffers from volume expansion seriously in the repeated charging and discharging processes along with p ...

This study established a highly quantitative detection system for HuNoV VLP entry into live cells based on the NanoLuc luciferase complementation. First, we generated a HiBiT-tagged VLP and examined VLP-HiBiT entry into Vero cell ...

Abstract:
... Vaporizable hydrocarbon-in-fluorocarbon endoskeletal droplets are a unique category of phase-change emulsions with interesting physical and thermodynamic features. Here, we show microfluidic fabrication of various morphologies, such as solid-in-liquid, liquid-in-solid, and Janus-type, of complex solid n-C₂₀H₄₂ or n-C₂₁H₄₄ and liquid n-C₅F₁₂ droplets. Furthermore, we investigated the vaporization b ...

Abstract:
... Amorphous solid dispersion (ASD) technique is promising to increase the dissolution of hydrophobic drug in aqueous solution systems, including in vivo. However, there is a serious lack of understanding of the impact of the molecular characteristics of a hydrophobic drug on the aqueous dissolution behavior of the drug from the ASD. This is because there are many structural differences between diffe ...

Abstract:
... Pyrolysis is a technical means for waste tires recycling, which can promote the enrichment of carbon black and facilitate the subsequent recovery. However, carbon black particles aggregated and the inorganic impurities tended to be enriched in pyrolytic char during the waste tire pyrolysis process, which is not conducive to the substitution of commercial carbon black by pyrolytic char. In the pres ...

Abstract:
... Several polyphenol compounds commonly found in plant foods provide health benefits that promote their applications in food and pharmaceutical fields. The co-loading of proteins can improve the biological activity and synergy of combined polyphenols. Herein, multi-spectroscopic techniques and molecular docking were employed to investigate the interactions of native/heat treated β-lactoglobulin (β-L ...

Abstract:
... The layered manganese-based lithium-rich oxide (LLO) cathode material is considered one of the most attractive cathode material candidates for next-generation lithium-ion batteries due to its high specific capacity. However, LLOs suffer from low coulombic efficiency as well as cycle capacity decay due to oxygen release and structural transformation during the first charge. Here, we report a simple ...

Abstract:
... The rubberized self-compacting concrete (RSCC) combines the better ductility and toughness of rubber aggregates and the better working performance of self-compacting concrete (SCC), and has gained popularity. In practice, concrete structures often suffer multiple impacts loading during their service life. Therefore, this work investigates the dynamic compressive properties of RSCC under multiple i ...

Abstract:
... Nanostructured Ferritic Alloys (NFAs) are candidate materials for use as cladding inside future nuclear reactors. The high number density of nano-sized (< 2 nm diameter) oxide particles are critical to the NFA’s advantageous material properties against irradiation. A Kinetic Monte Carlo (KMC) model was developed to simulate the precipitation of yttrium-oxygen (Y–O) and yttrium-titanium-oxygen (Y–T ...

... The monomer concentration is a key factor affecting the diffusion rate and reaction rate of the monomers and determines the physicochemical property of polyamide nanofiltration membranes. However, the mechanism of the monomer concentration effect on the polyamide nanofiltration membrane remains unclear. The properties of nascent membranes fabricated with different monomer concentrations with a fix ...

Abstract:
... Antimony selenosulfide, Sb₂(S,Se)₃, has emerged as a promising light-harvesting material due to its high absorption coefficient, suitable bandgap, and low-toxic and low-cost constituents. Previously, high-efficiency Sb₂(S,Se)₃ solar cells were fabricated exclusively using Spiro-OMeTAD as the hole-transporting layer (HTL) with an n–i–p device architecture. However, the poor stability and high cost ...
