Investigation of Nsingle bondH⋯O interactions in N-monosubstituted caproamide – Ether systems: FT–IR and FT–NIR spectroscopic study
(Elsevier Science Bv, Amsterdam, 2019)
This paper reports FT-IR and FT-NIR spectroscopic study of hydrogen bonding between N-mono-substituted caproamides and different ethers (diethyl ether and tetrahydrofuran) in carbon tetrachloride. With increase in ether ...
Migration of cypermethrin to and through the PET containers and artificial neural network-based estimation of its emission
(Springer Verlag, 2019)
Nowadays, the extensive use of pesticides in crops production puts a significant challenge to minimize its side effects along with safe production, storage, and after-use treatment. This paper reports results related to ...
Polyamidoamine as a clay modifier and curing agent in preparation of epoxy nanocomposites
(Elsevier Science Sa, Lausanne, 2019)
In the present study the commercial multifunctional fatty acid polyamidoamine (PAA) was for the first time simultaneously applied as a curing agent and clay modifier for epoxy/clay nanocomposites (NC) based on diglycidyl ...
Thermal analysis of polylactic acid under high CO2 pressure applied in supercritical impregnation and foaming process design
(Elsevier Science Bv, Amsterdam, 2019)
Thermal properties of extrusion and injection grade polylactic acid (PLA) were analysed using high pressure differential scanning calorimetry (HP-DSC) under CO2 pressures of up to 50 MPa. The greatest depression of melting ...
Effects of tomato processing on carotenoids antioxidant activity and stability during one-year storage
(Bulgarian Chemical Communications, 2019)
The degradation of carotenoids (lycopene and β-carotene) and total antioxidant activity was investigated after one- year storage of pasteurized tomato juice. Tomato juice, thermally treated for 7 min at 100°C, was subjected ...
Assembling Mesoscale-Structured Organic Interfaces in Perovskite Photovoltaics
(Wiley-VCH Verlag Gmbh, Weinheim, 2019)
Mesoscale-structured materials offer broad opportunities in extremely diverse applications owing to their high surface areas, tunable surface energy, and large pore volume. These benefits may improve the performance of ...
Influence of different concentrations of Zn-carbonate phase on physical-chemical properties of antimicrobial agar composite films
(Elsevier, Amsterdam, 2019)
Agar-based composites with different Zn-carbonate mineral phase content were prepared by in situ mineralization and the solvent casting method. The mineral phase within the composite films was identified as hydrozincite, ...
Novel nano-composite hydrogels with honey effective against multi-resistant clinical strains of Acinetobacter baumannii and Pseudomonas aeruginosa
(Springer, New York, 2019)
Novel alginate hydrogels with silver nanoparticles (AgNPs) and honey components were produced with the aim to target multidrug-resistant bacterial strains causing nosocomial wound infections. AgNP synthesis was optimized ...
Biodegradation of poly(epsilon-caprolactone) (PCL) and medium chain length polyhydroxyalkanoate (mcl-PHA) using whole cells and cell free protein preparations of Pseudomonas and Streptomyces strains grown on waste cooking oil
(Elsevier Sci Ltd, Oxford, 2019)
Petrochemical plastics are generally recalcitrant to microbial degradation and accumulate in the environment. Biodegradable polymers obtained synthetically like poly(epsilon-caprolactone) (PCL) or poly-hydroxyalkanoates ...
Biomimetic characterization reveals enhancement of hydroxyapatite formation by fluid flow in gellan gum and bioactive glass composite scaffolds
(Elsevier Sci Ltd, Oxford, 2019)
This study presents production and biomimetic characterization of macroporous composite scaffolds based on gellan gum and nanoparticulate bioactive glass (GG-BAG) under conditions relevant for bone tissue engineering. ...
