Marangoni effect and cell spreading
(Springer Science and Business Media Deutschland GmbH, 2022)
Cells are very sensitive to the shear stress (SS). However, undesirable SS is generated during physiological process such as collective cell migration (CCM) and influences the biological processes such as morphogenesis, ...
Influence of chloride ion concentration on initial corrosion of AZ63 magnesium alloy
(Nonferrous Metals Society of China, 2022)
The initial corrosion behavior of AZ63 magnesium alloy was investigated in 1, 3, 5 and 7 wt.% NaCl solutions by means of corrosion potential, linear polarization, electrochemical impedance spectroscopy, and polarization ...
Ultrasound-assisted extraction of essential and toxic elements from pepper in different ripening stages using Box–Behnken design
(John Wiley and Sons Inc., 2022)
The influence of extraction parameters on the ultrasonically assisted extraction (UAE) of K, Na, Ca, Mg, Zn, Cu, Fe, Mn, Cr, Se, Mo, Li, Al, B, Pb, Hg, Cd, As, and Ni was studied to determine the conditions when a minimum ...
Principal component analysis of morphological descriptors for monitoring surface defects induced by thermal shock
(Elsevier Ltd, 2021)
Pattern recognition techniques are applied to various morphological descriptors to monitor the formation and propagation of surface defects of materials subjected to thermal shock. A low-cement high-alumina castable was ...
The overlooked potential of raspberry canes: from waste to an efficient low-cost biosorbent for Cr(VI) ions
(Springer Science and Business Media Deutschland GmbH, 2022)
Screening of various potential biosorbents originated from locally available lignocellulosic biomass has led to the investigation of so far uninvestigated raspberry cane for removal of Cr(VI) ions from aqueous solutions. ...
Acetylation of cellulose – Another pathway of natural cellulose aging during library storage of books and papers
(Elsevier Ltd, 2022)
Gaseous acetic acid is formed under conditions of storage of historic paper objects. Its presence not only promotes hydrolytic cleavage of cellulose, but also causes acetylation of the cellulosic material to very small ...
Supercritical CO2-assisted processes for development of added-value materials: Optimization of starch aerogels preparation and hemp seed extracts impregnation
(Elsevier Ltd, 2022)
The aim of the present study was the utilization of supercritical CO2 as a green medium in various processes: starch gel drying, supercritical extraction from hemp seed flour (SCE process), hemp seed oil (HSO) impregnation ...
Modification of CaCO3 and CaCO3 pin-coated cellulose paper under supercritical carbon dioxide-ethanol mixture for enhanced NO2 capture
(Environmental Science and Pollution Research, 2022)
In this work, we examine two modifications of fine-ground calcium carbonate material (GCC) in order to enhanced sorption of NO2 and subsequent reaction properties toward NO2-/NO3- formation by firstly exposing the GCC to ...
Highly Active Rutile TiO2 Nanocrystalline Photocatalysts
(Amer Chemical Soc, Washington, 2020)
The controllable synthesis of rutile TiO2 single crystal particles with the preferential orientation of {111} facets still remains a scientific and technological challenge. Here, we developed a facile route for fabrication ...
Antibacterial Activity of pH-Sensitive Silver(I)/Poly(2-hydroxyethyl acrylate/itaconic acid) Hydrogels
(Polymer Soc Korea, Seoul, 2020)
Since the management of infections becomes prior global healthcare issue, the "post antibiotic era" requires innovative and interdisciplinary approach. As an alternative to widespread and, nowdays mostly uneffective, ...
