Wastes from bioethanol and beer productions as substrates for L(+) lactic acid production - A comparative
(Pergamon-Elsevier Science Ltd, Oxford, 2016)
Waste substrates from bioethanol and beer productions are cheap, abundant and renewable substrates for biorefinery production of lactic acid (LA) and variability in their chemical composition presents a challenge in their ...
Characterization of scaffolds based on chitosan and collagen with glycosaminoglycans and sodium alginate addition
(Elsevier Sci Ltd, Oxford, 2018)
Scaffolds based on chitosan (CTS), collagen (Coll), and glycosaminoglycans (GAGs) cross-linked by sodium alginate (SA) were obtained with the use of the freeze-drying method. They were characterized by different analyses, ...
Abnormalities in the ovule development of the European plum cultivar 'Pozna Plava' in the days following anthesis
(Elsevier Science Bv, Amsterdam, 2019)
Factors such as the stage of ovule maturity and longevity at flowering, when the stigma is able to receive the pollen, are significant in terms of fruit set. Various abnormalities during ovule development can often limit ...
Chromatographic and in silico assessment of logP measures for new spirohydantoin derivatives with anticancer activity
(Wiley, Hoboken, 2018)
Lipophilicity has, for a long time, been recognized as a meaningful parameter in structure-activity relationships. It is also the single most informative physicochemical property that reveals a wealth of information on ...
The effect of graphene loading on mechanical, thermal and biological properties of poly(vinyl alcohol)/graphene nanocomposites
(Elsevier Science Inc, New York, 2016)
Poly(vinyl alcohol)/graphene (PVA/Gr) nanocomposite was synthesized with the aim of developing a novel improved material. The PVA/Gr nanocomposite was characterized by UV-visible spectroscopy, cyclic voltammetry, Raman ...
Functionalization of polypropylene, polyamide and cellulose acetate materials with pyrethrum extract as a natural repellent in supercritical carbon dioxide
(Elsevier Science Bv, Amsterdam, 2018)
This study discusses the possibility of supercritical solvent impregnation of polypropylene and polyamide fabrics as well as cellulose acetate in the form of beads and films with pyrethrum extract in order to fabricate ...
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 ...
Numerical simulation of fatigue crack propagation: A case study of defected steam pipeline
(Elsevier Ltd, 2019)
In order to prevent the premature failure of steam pipeline produced of molybdenum-vanadium steel, the experimental tests were performed to measure fracture toughness and to determine the mechanical behaviour of cracked ...
Supercapacitive Performances of Activated Highly Microporous Natural Carbon Macrofibers
(Electrochemical Soc Inc, Pennington, 2017)
Activated carbons with high specific surface area (even above 2000 m(2) g(-1)) and pronounced microporosity are prepared in two-stage process involving conventional carbonization of waste hemp fibers and subsequent activation ...
