Cultured meat is artificial meat produced via the mass culture of cells without slaughtering livestock. In the production process of cultured meat, the mass proliferation for preparing abundant cells is a strenuous and time-consuming procedure requiring expensive and excess serum. Herein, C-phycocyanin (C-PC) extracted from blue algae was selected as a substitute for animal-derived serum and a polysaccharide film-based platform was developed to effectively deliver C-PC to myoblast while reducing
Abstract To address the poor oil–water separation efficiency and bactericidal properties of existing oil–water separation membranes for the treatment of industrial oily wastewater discharge, this study designed an in-and-out coating material for modifying the inner site and outer surface of porous activated carbon fabric (ACF) using urethane reactions. To this end, fluorinated polyurethane (F-PU) coating materials were synthesized using perfluoroalkyl alcohol, ethylene glycol (EG), and isophoron
SYNOPSIS. Multilayered graphene oxide-carbonic anhydrase membrane suggests a new insight into CO 2 separation as it provides a precisely tailored internal structure. • Carbonic anhydrase (CA) was physically or chemically interacted with graphene oxide (GO) for evaluation of enzymatic separation. • Spray-assisted GO-NH 3 + /Ch-GO-CA or GO-NH 3 + /Ph-GO-CA LbL nano-membrane were fabricated by hydrogen bonding and electrostatic interaction. • The Ph-GO-CA in physisorption-based nano-membrane can co
With the growing interest in chemical and biological warfare agents (CWAs/BWAs), the focus has shifted toward aerosol protection using protective clothing. However, compared to air-permeable membranes, those with water vapor permeability have been investigated more extensively. Filtering membranes without air permeability have limited practical usage in personal protective suits and masks. In this study, polyacrylonitrile membranes with tightly attached activated carbon and doped copper(II) oxid
Oxidation stability and cold fuid property are considered as the most important factors for determining biodiesel quality. Among the fatty acids, monounsaturated fatty acid satisfy both oxidation stability and cold flow property of biodiesel quality standards. Microalgae with high monounsaturated fatty acid contents is have some benefit for producing to produce biodiesels with satisfying quality standards. In this study, monounsaturated fatty acid contents of a isolated microalga from Youngheung
With the rapidly growing global aging population, muscle atrophy affects ≈40% of older individuals, leading to severe impairments in daily activities. However, its treatment remains challenging due to adverse effects associated with drug accumulation, the difficulty of delivering drugs specifically to deep muscle tissues, and the inherent limitations of current therapeutic devices that rely on wired connections or battery-dependent external power systems. In this study, a body-coupled on-target
