网页The permeation of gases through polymer membranes is usually described in terms of a ‘‘solution-diffusion’’ mechanism. It consists of the following steps: (1) solution (absorption) of small molecules into the membrane at the side of higher potential (pressure, concentration, etc.); (2) molecular diffusion of the molecules in and through
网页2022年12月9日 · Reporter genes are important tools in many biological disciplines. The discovery of novel reporter genes is relatively rare. However, known reporter genes are constantly applied to novel applications. This study reports the performance of the bilirubin-dependent fluorescent protein UnaG from the Japanese eel Anguilla japonicas in live
网页1998年5月1日 · We have investigated the regulation of the permeability transition pore (PTP), a cyclosporin A-sensitive channel, in rat skeletal muscle mitochondria. As is the case with mitochondria isolated from a variety of sources, skeletal muscle mitochondria can undergo a permeability transition following Ca2+uptake in the presence of Pi. We find
网页2020年12月3日 · a porous filter fabricated via CAPC, this study focused on gas permeability, especially by experimentally measuring the N 2 permeability, and on its relationship with porosity. 2. Materials and Methods Figure 1
网页2013年4月18日 · byPaul Haney, Ph.D.; Katherine Herting, B.S.; Suzanne Smith, M.S. - 04/18/13. Dialysis is a classic laboratory technique that relies on selective diffusion of molecules across a semi-permeable membrane to separate molecules based on size. Dialysis is used for a wide variety of applications: desalting, buffer exchange, removal of
网页2022年12月30日 · 4.2: Membrane Permeability. A pure phospholipid bilayer, whatever the lipid composition, is a semi-permeable membrane that is generally repellent to large
网页Methods for Measuring Permeability. A variety of methods exist to measure microvascular or endothelial permeability to fluid and/or solutes. Historically, these methods are designed to determine one of several distinctly different, though related mathematical values describing permeability of the capillary wall: the filtration coefficient ( Kf
网页2022年11月17日 · Last Modified Date: November 17, 2022. Membrane filtration is a technique which is used to separate particles from a liquid for the purpose of purifying it. This filtration method has a number of applications, ranging from treating wastewater to filtering milk used for cheese production, and there are several different approaches to
网页2022年7月13日 · The membrane-based electrolysis of water is a growing topic of interest due to the advantages of employing membranes in hydrogen production efficiency and system safety over the traditional alkaline water electrolysis. Ion-exchange membranes with low gas permeability are highly desirable for stable and safe operation of membrane
