Determination of LCF Plastic and Elastic Strain Components of Steel
(Springer Science and Business Media B.V., 2022)
The behavior of steel in low-cycle fatigue (LCF) is tested experimentally, in accordance with ISO 12106:2017 (E) and/or ASTM E 606-04. For this purpose, smooth specimens which are exposed to low-cycle fatigue at several ...
Saddle Point Optimality Criteria and Duality for Convex Continuous-Time Programming Problem
(Department of Mathematics, Faculty of Science and Mathematics, University of Niš, 2022)
In this paper, convex continuous-time programming problem with inequality type of constraints is considered. We derive new saddle point optimality conditions and classical duality results such as weak and strong duality ...
Impact of Crosslinking on the Characteristics of Pectin Monolith Cryogels
(MDPI, 2022)
In this research, the pectin monoliths were prepared via the sol-gel process through different routes of crosslinking and additional freeze-drying. The crosslinking reaction was induced by the use of calcium ions in aqueous ...
Optimization of Pretreatment Conditions and Enzymatic Hydrolysis of Corn Cobs for Production of Microbial Lipids by Trichosporon oleaginosus
(MDPI, 2022)
Microbial lipids produced from lignocellulosic biomass are sustainable alternative feedstock for biodiesel production. In this study, corn cobs were used as a carbon source for lipid production and growth of oleaginous ...
A review of the electrochemical corrosion of metals in choline chloride based deep eutectic solvents
(Journal of Electrochemical Science and Engineering, 2022)
Deep eutectic solvents (DESs) are a class of mixtures with melting points notably lower than those of their raw constituent components. These liquids have found a tremendously wide spectrum of applications in the last two ...
Closing the Loop: Dyeing and Adsorption Potential of Mulberry Wood Waste
(Journal of Natural Fibers, 2022)
This study reports the successful transformation of mulberry wood waste into natural textile dye and adsorbent for Pb2+ ions from an aqueous solution. Fabrics of different chemical compositions were dyed using mulberry ...
Methacrylate-Based Polymeric Sorbents for Recovery of Metals from Aqueous Solutions
(MDPI, 2022)
The industrialization and urbanization expansion have increased the demand for precious and rare earth elements (REEs). In addition, environmental concerns regarding the toxic effects of heavy metals on living organisms ...
