Mechanical waves caused by collective cell migration: generation
(European Biophysics Journal With Biophysics Letters, 2022)
Long-timescale viscoelasticity caused by collective cell migration (CCM) significantly influences cell rearrangement and induces generation of mechanical waves. The phenomenon represents a product of the active turbulence ...
Transesterification of used cooking sunflower oil catalyzed by hazelnut shell ash
(Renewable Energy, 2022)
Hazelnut shell ash was investigated as a new base catalyst for the transesterification of used cooking sunflower oil to biodiesel. To understand its catalytic properties, the prepared ash was characterized by EDX, XRD, ...
Thermal Design Method for Optimization of Dry Heat Transfer through Hemp-Based Knitted Fabrics
(Taylor and Francis Ltd., 2022)
In the present research, folding of yarns was applied as a method for designing thermal transport characteristics of hemp-based knits. The rib-knitted fabrics were made by combining one of two cotton two-folded yarns ...
Electro-physical Properties of Woven Clothing Fabrics Before and After Abrasion
(Taylor and Francis Ltd., 2022)
In this investigation, the electro-physical properties (DC volume electrical resistivity, and AC-specific electrical conductivity) of woven fabrics (cotton, cotton/polyester, and flax in plain weave and cotton in satin ...
Structural, Mechanical and Electrical Characteristics of Copper Coatings Obtained by Various Electrodeposition Processes
(Electronics, 2022)
Mechanical (hardness and adhesion) and electrical (sheet resistance) characteristics of electrolytically produced copper coatings have been investigated. Morphologies of Cu coatings produced galvanostatically at two current ...
Macrophages, the main marker in biocompatibility evaluation of new hydrogels after subcutaneous implantation in rats
(Journal of Biomaterials Applications, 2022)
Biocompatibility of materials is one of the most important conditions for their successful application in tissue regeneration and repair. Cell-surface interactions stimulate adhesion and activation of macrophages whose ...
