Abstract A new Hf-based Hf-Cu-Ni-Al-Ag glassy alloy was synthesized to be formed by copper mold casting. The influence of Ag addition on the properties Hf 48 Cu 29.25 Ni 9.75 Al 13-x x (x=0-5at%) alloys studied differential scanning calorimeter, X-ray diffractometer, quasi-static compression, and electrochemical corrosion test. experimental results show that adding can improve thermal stability...

Piroxicam, an anti-inflammatory drug, exhibits poor water solubility and flow properties, poor dissolution and poor wetting. Consequently, the aim of this study was to improve the dissolution of piroxicam. Microparticles containing piroxicam were produced by spray drying, using isopropyl alcohol and water in the ratio of 40:60 v/v as solvent system, and spray chilling technology by melting the ...

Background and Objective: Quick-frozen dumpling is widely consumed in China. Inclusion Potato Granule (PG) into dumpling wrappers will extend utilization of this cheap flour in the staple food. The objective of this study was to evaluate the feasibility of partial substitution of wheat flour with PG in the dumpling wrappers. Methodology: In this study, cooking qualities of dumpling wrappers con...

Microencapsulated paraffin wax/polyaniline was prepared using a simple in situ polymerization technique, and its performance characteristics were investigated. Weight losses of samples were determined by Thermal Gravimetry Analysis (TGA). The microencapsulated samples with 23% and 49% paraffin showed less decomposition after 330 °C than with higher percentage of paraffin. These samples were the...

Hollow fiber membrane offers the advantage to integrate catalytic conversion, product separation and catalyst recovery into a single separation process compared to conventional systems. Polypropylene (PP) hollow fiber membrane is a chemically inert and stable membrane with high potential for enzyme immobilization. The surface properties of polypropylene have been modified by radiation induced g...

OBJECTIVE To analyze a new endodontic sealer material commercially known as Resilon and to describe in detail the experimental techniques employed that lead to the identification of the composite material. METHODS An extensive structural, thermal, and physical characterization was used to identify a new endodontic sealer material using the following techniques: Fourier transform infrared (FTI...

This paper is focused on preparation and performance analysis of a series of form-stable phase change materials (FSPCMs), based on eutectic mixtures as phase change materials (PCMs) for thermal energy storage and high-density polyethylene (HDPE)-ethylene-vinyl acetate (EVA) polymer as supporting materials. The PCMs were eutectic mixtures of tetradecanol (TD)-capric acid (CA), TD-lauric acid (LA...

Currently, the mechanical performances of polylactic acid (PLA) samples prepared using fused filament fabrication (FFF) technique are relatively poor. Hence, carbon fiber (CF) is used to improve thermal stability and property FFF-ed PLA in this paper. The crystalline structure, stability, melt flow rate, tensile strength fractured surface morphology PLA/CF were investigated with an X-ray diffra...

Phase change materials (PCMs), as latent thermal energy storage, have received plenty of attention in recent decades due to their excellent performance conservation. Inorganic hydrated salts many advantages over organic phase materials, such higher storage density, low cost, nontoxicity and nonflammability. This work presents a simple environmentally friendly method for the preparation microcap...
