The aim of this investigation was to develop a procedure to improve the dissolution and bioavailability of silymarin (SM) by using bile salt-containing liposomes that were prepared by supercritical fluid technology (ie, solution-enhanced dispersion by supercritical fluids [SEDS]). The process for the preparation of SM-loaded liposomes containing a bile salt (SM-Lip-SEDS) was optimized using a c...

Magnesium-aluminum layered double hydroxides intercalated with antitumor drug etoposide (VP16) were prepared for the first time using a two-step procedure. The X-ray powder diffraction data suggested the intercalation of VP16 into layers with the increased basal spacing from 0.84-1.18 nm was successful. Then, it was characterized by X-ray powder diffraction, Fourier transform infrared spectrosc...

Abstract Magnetic actuation has attracted a growing attention due to its non‐contact performance, rapid response and penetrability. The realization of magnetic requires the participation magneto‐responsive materials (MRMS), polymers (MRPs) are one most widely used MRMs. Here, we report fabrication, characterization tests neodymium‐iron‐boron‐polydimethylsiloxane (NdFeB‐PDMS) films. NdFeB‐PDMS f...

Purpose This study aims to examine on-site particle concentration levels due emissions from a wide spectrum of additive manufacturing techniques, including polymer-based material extrusion, metal and powder bed fusion, directed energy deposition ink-based jetting. Design/methodology/approach Particle concentrations in the operating environments users were measured using combination sizers TSI 3...

Powder mixing has been the subject of substantial research due to its importance in a variety of industrial sectors, including pharmaceuticals, food, and polymer manufacturing. Although a number of different models have been proposed in the literature, most of them are either empirical or require computationally intensive calculations that make them difficult to implement for realistic systems....

Job tasks that involve exposure to work-related musculoskeletal disorder (WMSD) risk factors may impact both the risk of injury and production downtime. Common WMSD risks factors associated with mining tasks include forceful exertions, awkward postures, repetitive motion, jolting and jarring, forceful gripping, contact stress, and whole body and segmental vibration. Mining environments that exp...

A new poly(amidoamine)-cholesterol (PAA-cholesterol) conjugate was synthesized, characterized and used to produce nanoparticles by the electrospraying technique. The electrospraying is a method of liquid atomization that consists in the dispersion of a solution into small charged droplets by an electric field. Tuning the electrospraying process parameters spherical PAA-chol nanoparticles formed...
