Bioprocessing of agro-industrial residues into lactic acid and probiotic enriched livestock feed
(Wiley, Hoboken, 2019)
BACKGROUND Growing challenges of resource depletion, food security and environmental protection are putting stress on the development of biorefinery processes for bioprocessing of residues from food and agro-industry into ...
The influence of alumina crystal structures on the morphology and surface erosion of PMMA composite materials exposed to cavitation testing
(Elsevier Science Sa, Lausanne, 2019)
Composites are materials that reach many users and therefore, it is necessary to correlate the properties of every component on the behaviour of the material. Alumina is used as reinforcement with the aim of improving ...
Kinetic models of swelling and thermal stability of silver/poly(vinyl Check far alcohol)/chitosan/graphene hydrogels
(Elsevier Science Inc, New York, 2019)
Silver nanoparticles (AgNPs) were synthesized by in situ electrochemical reduction of Ag+ ions in poly (vinyl alcohol)/chitosan/graphene (PVA/CHI/Gr) hydrogel matrices with different concentrations of chitosan. The ...
Utilization of brewing and malting by-products as carrier and raw materials in l-(+)-lactic acid production and feed application
(Springer, New York, 2019)
Application of agro-industrial by-products for the production of lactic acid was studied in this paper. Brewer's spent grain (BSG), malt rootlets (MR), brewer's yeast (BY), and soy lecithin (SL) were used as raw materials ...
Casein-poly(methacrylic acid) hybrid soft networks with easy tunable properties
(Pergamon-Elsevier Science Ltd, Oxford, 2019)
The design of complex polymeric materials with predefined task-specific properties meets challenging issues: to establish synthesis-structure-properties relationship, as well as to understand the arrangement and interactions ...
Supercritical CO2 - assisted production of PLA and PLGA foams for controlled thymol release
(Elsevier Science Bv, Amsterdam, 2019)
Amorphous, medical grade poly(D,L-lactic acid) (PLA) and poly(D,L-lactic-co-glycolic acid) (PLGA) were used to develop systems for controlled release of a natural bioactive substance - thymol. Supercritical carbon dioxide ...
Numerical simulation of fatigue crack propagation: A case study of defected steam pipeline
(Pergamon-Elsevier Science Ltd, Oxford, 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 ...
Broad Spectrum of Antimicrobial Activity of Cotton Fabric Modified with Oxalic Acid and CuO/Cu2O Nanoparticles
(Korean Fiber Soc, Seoul, 2019)
This study discusses the possibility of fabrication of textile nanocomposites with antimicrobial activity against antibiotics-resistant bacterial strains and yeast. Modification of cotton fabric with oxalic acid solutions ...
The influence of the surface nanostructured modification on the corrosion resistance of the ultrafine-grained Ti-13Nb-13Zr alloy in artificial saliva
(Elsevier, Amsterdam, 2019)
On the surface of the ultrafine-grained Ti-13Nb-13Zr alloy and the coarse-grained Ti-13Nb-13Zr alloy nanotubular oxide layers were formed by electrochemical anodization in the 1 M H3PO4 + NaF electrolyte in order to evaluate ...
Novel protein-repellent and antimicrobial polysaccharide multilayer thin films
(Walter de Gruyter Gmbh, Berlin, 2019)
Nanostructured and bio-active polysaccharide-based thin films were manufactured by means of subsequent spin-coated deposition of a regenerated cellulose (RC) layer and a 2,2,6,6-Tetramethylpiperidine-1-oxyl radical (TEMPO) ...
