Deposit formation and fouling in reactors for polymer production processing especially microreactors is a well-known phenomenon. Despite the flow pressure loss optimized static mixers, occurs on surfaces of mixer elements. To improve performance such parts even further, stainless steel substrates are coated with ultra-thin films which have low surface energy, good adhesion, high durability. Per...

L-DOPA (3,4-dihydroxyphenyl-L-alanine) is a drug of choice in Parkinson's disease treatment. However the chemical method its synthesis has number drawbacks, so biotechnological approaches are being explored as an alternative. Aim. The goal to develop new affordable and effective biosynthesis using mushroom tyrosinase, immobilized economical carrier, which ensures stability enzyme multiple uses....

Objective(s): The present study aimed to evaluate the capability of synthesized and modified superparamagnetic iron oxide nanoparticles (SPIONs) as the positive contrast agent in magnetic resonance imaging (MRI) by investigating the effect of repetition time (TR) on the MRI signal intensity. Materials and Methods: SPIONs were synthesized using the co-precipitation method, and their surfac...

NiCr2O4 normal spinel nanostructures were prepared via hydrothermal treatment at 180 °C for 12 h in the presence of cetyltrimethylammonium bromide (CTAB), sodium dodecyl sulphate (SDS) and poly vinylpyrrolidone-25000 (PVP-25000) as capping agents and subsequent calcination process at 500 °C for 3 h . In this method, [Ni(en)2(H2O)...
