Flavonoid esters synthesis using novel biocatalytic systems - CAL B immobilized onto LifeTech (TM) ECR supports
(Elsevier B.V., 2020)
In order to enhance productivity and cost-effectiveness of current lipase-catalyzed processes of flavonoid esters synthesis, different LifeTech (TM) ECR carriers varying in functional groups, polarity and porosity were ...
Antibacterial activity of thymol/carvacrol and clinoptilolite composites prepared by supercritical solvent impregnation
(Journal of Porous Materials, 2021)
Novel composites based on natural zeolite-clinoptilolite and monoterpene phenols-thymol and carvacrol were prepared by supercritical solvent impregnation (SSI) in supercritical carbon dioxide (scCO(2)) at 30 MPa and 35 ...
Novel strategy for encapsulation and targeted delivery of poorly water-soluble active substances
(Wiley, Hoboken, 2020)
Carriers for targeted delivery and controlled release of poorly water-soluble active substances (PWSAS) are facing three challenges: (a) the encapsulation issues, (b) limitations of PWSAS water solubility, and
Selective Antimicrobial Performance of Biosynthesized Silver Nanoparticles by Horsetail Extract Against E. coli
(Springer, Dordrecht, 2020)
The aim of this study was the development of a non-toxic, biosynthetic antimicrobial agent which selectively acts on only one type of microorganism, and preserves the microbiota. Antimicrobial performance of biosynthesized ...
The effect of natural modifiers for starch hydrophobization on performance of composite based on ethylene acrylic acid copolymer
(Wiley, Hoboken, 2021)
As a renewable resource, starch is considered to be fully biodegradable and nonpolluting to the environment but the hygroscopicity of starch is the main disadvantage for wider applicability in the production of a polymer-based ...
Composition-property relationship of polyurethane networks based on polycaprolactone diol
(Springer, New York, 2021)
This work was focused on the synthesis of polyurethane networks (PUNs) based on polycaprolactone (PCL) as soft segment (SS) and Boltorn (R) aliphatic hyperbranched polyester of the second pseudo generation and 4,4 ...
Preparation of floating polymer-valsartan delivery systems using supercritical CO2
(Journal of Polymer Research, 2021)
This study investigates pharmaceutical polymers (Soluplus((R)), HPMCAS, and Eudragit((R)) E100) and supercritical CO2-assisted process for preparation of floating valsartan delivery systems. Tested process (at pressure of ...
Design of halloysite modification for improvement of mechanical properties of the epoxy based nanocomposites
(Polymer Composites, 2021)
In this study, halloysite nanotubes (HNT) were modified by: 3-glycidyloxypropyltrimethoxysilane (GLYMO), 3-aminopropyltrimethoxysilane (APTES), and 2,2-Bis[4-(glycidyloxy) phenyl] propane (DGEBA), and incorporated in the ...
Enzymatically derived oil-based L-ascorbyl esters: Synthesis, antioxidant properties and controlled release from cosmetic formulations
(Elsevier B.V., 2020)
Lipase-catalyzed transesterification of vitamin C by natural triglycerides is promising approach for cost-efficient synthesis of liposoluble food and cosmetic antioxidants. Nevertheless, application of these alternative ...
Solvent effects on structural changes in self-healing epoxy composites
(Elsevier Science Sa, Lausanne, 2020)
Nowadays, there is a very high importance of composite research and variety of their applications in the modern world. In that sense, we researched hollow glass capillaries filled with dissolved Grubbs catalyst (GC) and ...
