Towards sustainability of lactic acid and poly-lactic acid polymers production
(Pergamon-Elsevier Science Ltd, Oxford, 2019)
Lactic acid (LA) is a platform chemical which can be produced biotechnologically on agricultural residues, wastes and by-products and further used for production of biodegradable, biocompatible LA polymers. These polymers ...
Application of the Integrated Supercritical Fluid Extraction–Impregnation Process (SFE-SSI) for Development of Materials with Antiviral Properties
(MDPI, 2022)
The integrated supercritical fluid extraction–impregnation process (SFE-SSI) was performed to fabricate material with antiviral properties against the herpes simplex virus (HSV). Cotton gauze and starch/chitosan polymer ...
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 ...
Review on Adhesives and Surface Treatments for Structural Applications: Recent Developments on Sustainability and Implementation for Metal and Composite Substrates
(Materials, 2020)
Using adhesives for connection technology has many benefits. It is cost-efficient, fast, and allows homogeneous stress distribution between the bonded surfaces. This paper gives an overview on the current state of knowledge ...
Influence of TEMPO-Mediated Oxidation on Properties of Hemp Fibers
(Amer Chemical Soc, Washington, 2012)
Hemp fibers are a very interesting natural material for textile and technical applications, but some of these applications require improved and/or specific fiber properties. In order to modify hemp fibers for obtaining ...
The Rydberg atom-atom collisions: Chemi-ionization cross-sections and rate coefficients in alkali-metal astrophysical and low-temperature laboratory plasmas
(Elsevier Ltd, 2022)
In this manuscript, the chemi-ionization (CI) processes in atom - Rydberg atom collisions are examined. We obtained the cross-sections, as well as rate coefficients for CI processes in potassium and sodium collisions for ...
Studies of the Properties of Different Hard Coatings Resistant to Wear
(UNIVERSITY OF TIMISOARA, 2012)
Isopiestic determination of osmotic coefficients in the ionic strength range Im = (0.9670–2.2160) mol⋅kg−1 and activity coefficients determined by electromotive force measurements in the range Im = (0.0897–1.0054) mol⋅kg−1 of the {yKCl + (1 – y) K2HPO4}(aq) system at T = 298.15 K
(Elsevier B.V., 2022)
The mean activity coefficients of KCl in the ternary system {y KCl + (1 – y) K2HPO4}(aq) were experimentally determined at T = (298.15 ± 0.01) K by the electromotive force measurement (EMF method) using the cell of the ...
Removal of the As(V) and Cr(VI) from the Water Using Magnetite/3D-Printed Wollastonite Hybrid Adsorbent
(International Institute for the Science of Sintering (IISS), 2022)
In this study, the structure, morphology and composition of the synthesized magnetite/3D-printed wollastonite (3D_W/M) composite were characterized, and its adsorption performance with respect to As(V) and Cr(VI) were ...
