2010/11/24 · PTFE membrane displayed higher contact angles compared with P(VDF-TrFE)/BT, as indicated by wettability assay. The novel P(VDF-TrFE)/BT membrane supports the acquisition of the osteoblastic phenotype in vitro, while up-regulating the expression of apoptotic markers.
2013/12/10 · Optical waveguide lightmode spectroscopic (OWLS) techniques were probed for monitoring ion permeation through channels incorporated into artificial lipid environment. A novel sensor set-up was developed by depositing liposomes or cell-derived membrane fragments onto hydrophilic polytetrafluoroethylene (PTFE) membrane. The fibrous material of PTFE membrane could entrap lipoid

Filtration and regeneration behavior of polytetrafluoroethylene membrane for dusty gas treatment 745 Korean J. Chem. Eng.(Vol. 25, No. 4) ing pressure drop [18]. Some of them were based on computer pro-grams [15,16], and the simulated results well agreed with
1994/5/1 · Follows a presentation at a symposium in 1993 where the authors presented an experimental investigation on a fluttering membrane for use in a wind‐tunnel. Analyses the fluttering of an object by a theoretical method. Compares the experimental results with
Membrane Protein Aligned Sample Preparation: I • Exposure to extreme pH, organic solvents and elevated temperature must be avoided. Length of time from expression to stable environment must be minimized. • The general protocol involves detergent/lipid exchange by dialysis to prepare
This porous PTFE membrane may be a single-layer membrane. This porous PTFE membrane has the properties suitable for use as a waterproof air-permeable membrane, and achieves a good balance between high water resistance and high air permeability.
2020/6/1 · The PTFE membrane performance is tested in conventional air gap and multistage air gap membrane distillation set ups and validated against the data from prototypes reported in the literature []. Subsequently, the performance of a water distillation system that is similar to a solar still is experimentally determined, with and without the hydrophobic membrane.
This time, we will briefly introduce the PTFE garment membrane. Product description: The woven PTFE membrane uses a unique PTFE lamination technology to make e-PTFE into a microporous film with a diameter between 100-500 nanometers, and it has more than 1 billion pores per square centimeter, which is smaller than water vapor molecules, 700 times larger and 10,000 times smaller than water
2. In air gap membrane distillation (AGMD), water vapour is condensed on a cold surface that has been separated from the membrane via an air gap. The heat losses are reduced in this configuration by addition of a stagnant air gap between membrane and 3.
Composite membranes based on porous support membranes filled with a proton-conducting polymer appear to be a promising approach to develop novel proton exchange membranes (PEMs). It allows optimization of the properties of the filler and the matrix separately, e.g. for maximal conductivity of the former and maximal physical strength of the latter. In addition, the confinement itself can alter
