The potential of an advanced analytical strategy based on the use of gas chromatography (GC) coupled to high resolution mass spectrometry (HRMS) with two different analyzers and ionization sources has been investigated and applied to the non-target analysis of food packaging contaminants. Initially, the approach based on GC-time-of-flight (TOF) MS with electron ionization (EI) source allowed pe...

poly(vinyl acetate) is synthesized via solution polymerization, and then it is converted to poly(vinyl alcohol) by alkaline alcoholysis. the aim of the work study was to investigate statistically the  influence of reaction variables in vinyl acetate polymerization, the conversion of this monomer to polymer, degree of branching of acetyl group in poly(vinyl acetate), as well as the molecular wei...

Developing high-performance, low-cost and large-scale absorbent materials is crucial for the treatment of water pollution caused by pollutants leakage emission. Herein, superelastic superhydrophobic thermoplastic polymeric nanofibrous aerogels (NFAs) were created removal from using a facile effective method. Poly(vinyl alcohol-co-ethylene) (EVOH) nanofibers fabricated mass-production techniques...

poly vinyl alcohol/chitosan nanofibrous mat were prepared by electrospinning method with suitable pore sizes as potential matrices for soft tissue engineering. the designed scaffolds by electrospinning method evaluated by differentanalyses such morphological, mechanical, and cellular analysis.microscopic results showed diameters of poly vinyl alcohol/chitosan nanofibers were approximately 150 n...

A nanofiber mesh was prepared for the adsorption of indoxyl sulfate (IS), a toxin associated with chronic kidney disease. Removing IS is highly demanded efficient blood purification. The objective this study to develop zeolite composite remove efficiently. Eight zeolites different properties were used adsorption, where pore size 7 Å, H+ cations, and silica aluminum ratio 240 mol/mol exhibited h...

The Poly (vinyl alcohol)/Kefirane nanofiber membrane was successfully fabricated for the firsttime using electrospinning of the polyvinyl alcohol (PVA) and Kefirane blend solution. Scanningelectron microscope (SEM), attenuated total reflectance Fourier transform infrared (ATRFT-IR), and differential scanning calorimetry (DSC) were used to characterize the electrospunPoly (vinyl alcohol)/Kefiran...

Cassava cimplung is a traditional processed food made from cassava which boiled in coconut sap water. has not been widely produced ready-to-eat packaging as selling value food. This because semi-wet so it easily spoils and does last long. In an effort to maintain the quality of cimplung, this study thermal pasteurization process was carried out with variations length 10 minutes 15 use EVOH (Eth...
