Influence of Tool Tilt Angle on the Formation of Friction Stir Processing Zone in Cast Magnesium Alloy ZK60/SiCp Surface Composites

Abstract: Cast ZK60 magnesium alloy has significant beneficial properties including high strength-to-weight ratio. Poor surface properties such as low friction and wear resistance restrict the use of this alloy in structural applications. Therefore, it is very much essential to adopt surface engineering to enhance this alloy’s surface properties. Friction stir processing is one of the potential thermo-mechanical processing techniques that alters the microstructural and tribological properties of the material. In the present study, ZK60/SiCp was fabricated by means of FSP. Tool tilt angle is a critical process parameter which influences the material flow, and particle breakup and distribution in the processed zone. In this work, an attempt has been made to understand the effects of tool tilt angle (ranges 0°–4°) on the grain refinement of matrix and the distribution of SiC particles. It is shown that the FSPed materials zone produced using the tilt angle 2° exhibited higher hardness (125 Hv); this was attributed to the optimization of heat generation, material flow, grain boundary strengthening, and homogeneous particle distribution.

Preparation and characterization of cefditoren pivoxil-loaded liposomes for controlled in vitro and in vivo drug release

Abstract: Background The application of antibiotics has been limited due to weak biodistribution and pharmacokinetics. Encapsulation of these drugs in lipid vesicles might be a good solution for obtaining the required properties. Liposomes are one of the most suitable drug-delivery systems to deliver the drug to the target organ and minimize the distribution of the drug to non-target tissues.

Aflatoxins’ Clean-Up in Food Samples by Graphene Oxide–Polyvinyl Poly Pyrrolidone—Hollow Fiber Solid-Phase Microextraction

Abstract: The present investigation reports the synthesis of graphene oxide–polyvinyl poly pyrrolidone composite and its application in the extraction of aflatoxins in food samples. This composite was successfully synthesized and characterized with analytical instruments such as UV–Vis, FITR, XRD, and SEM techniques. The extraction was carried out by reinforced hollow fiber liquid-phase microextraction coupled with high-performance liquid chromatography (HPLC). Various parameters that affect the productivity of the present technique were exhaustively explored, and the quantifications were carried out under the optimized states. The limits of detection (LODs) were found to be 0.33, 0.10, 0.37, and 0.10 ng g−1, and limits of quantification (LOQs) were 1.10, 0.33, 1.24, and 0.33 ng g−1, respectively, for aflatoxins B1, B2, G1, and G2. The accuracy of the present method was determined based on the relative recovery (RR%) of the aflatoxins and the RR% of aflatoxins B1, B2, G1, and G2 which were found to be quite good (between 60.20 and 108.20 for 1 ng g−1 and between 62.02 and 95.39 for 5 ng g−1) in food samples. Applicability of the sorbent for the separation and quantification of the above-mentioned aflatoxins from food samples were examined. The developed method is straightforward, reliable, and effective, and has been successfully applied in determination of aflatoxins from food samples.
