  • thickness
  • Ultra-thin PCL membranes 5µm in thickness were prepared by solvent casting and biaxial stretching, and analyzed by atomic force microscopy (AFM). (arvojournals.org)
  • A 1:1 mixture of these peptides, which is known to possess synergistically enhanced activity, allowed us to evaluate whether and how this synergistic interaction correlates with changes in membrane thickness. (kit.edu)
  • When reconstituted as a mixture, PGLa and magainin 2 showed a moderate thinning effect which was less than that of magainin 2 alone, hence their synergistically enhanced activity does not seem to correlate with a modulation of membrane thickness. (kit.edu)
  • Instead, these results suggest that different factors contribute to the resulting changes in membrane thickness, such as the peptide orientation in the bilayer, and/or bilayer adaptation to hydrophobic mismatch. (kit.edu)
  • Membrane thickness did not affected significantly. (wikipedia.org)
  • desalination
  • An atomically thin membrane with microscopically small holes may prove to be the basis for future hydrogen fuel cells, water filtering and desalination membranes, according to a group of 15 theorists and experimentalists, including three theoretical researchers from Penn State. (psu.edu)
  • A hydrophilic, hydrostable porous metal organic framework (MOF) material-MIL-101 (Cr) was successfully doped into the dense selective polyamide (PA) layer on the polysulfone (PS) ultrafiltration (UF) support to prepare a new thin film nanocomposite (TFN) membrane for water desalination. (mdpi.com)
  • hydrogen
  • The team, led by Franz Geiger of Northwestern University, tested the possibility of using graphene, the robust single atomic layer carbon, as a separation membrane in water and found that naturally occurring defects, essentially a few missing carbon atoms, allowed hydrogen protons to cross the barrier at unprecedented speeds. (psu.edu)
  • molecules
  • This year they will show for the first time that these new films, membranes, and elastomers are compatible with diverse organic and inorganic molecules and will adopt properties of the guest molecules. (nanowerk.com)
  • The low energy attraction, means the guest molecules are widely dispersed throughout the membrane, which then takes on the properties of the guest molecules. (nanowerk.com)
  • The porous structures of MIL-101 (Cr) can establish direct water channels in the dense selective PA layer for water molecules to transport through quickly, leading to the increasing water permeance of membranes. (mdpi.com)
  • peptide
  • Other systems investigated here include the α-helical stress-response peptide TisB from E. coli (which forms membrane-spanning dimers), as well as gramicidin S from A. migulanus (a natural antibiotic), and BP100 (designer-made antimicrobial and cell penetrating peptide). (kit.edu)
  • Overall, the absence of a typical thinning response in the case of PGLa, and the increase in the repeat distance and membrane thickening observed for TisB, demonstrate that the concept of peptide-induced membrane thinning cannot be generalized. (kit.edu)
  • Pollutants
  • In the nasal cavity, a layer of mucous membrane acts as a filter and traps pollutants and other harmful substances found in the air. (wikipedia.org)
  • Whereas
  • Whereas a membrane already exposed to CO over several experiments was not enhanced after heat treatment in air. (bibsys.no)
  • Their findings revealed that the PAO membrane superiorly consisted of periosteum of the occiput, whereas inferiorly it formed part of the dura at the cerebrospinal junction, terminating at the level of the third cervical vertebra (rather than attaching to the posterior arch of the atlas). (wikipedia.org)
  • folds
  • The lungs are encased in a serous membrane that folds in on itself to form the pleurae - a two-layered protective barrier. (wikipedia.org)
  • separating layer
  • No one has actually been able to work out how the separating layer in a membrane is formed, or how to control the shape and size - the morphology - of that separating layer," says Professor Andrew Livingston, Head of the Department of Chemical Engineering at Imperial College London and who leads the BP International Centre for Advanced Materials (BP-ICAM) separations programme based at Imperial College London. (qeprize.org)
  • Firstly, we have found a way of making the separating layer of a membrane independently of the supporting layer," says Livingston. (qeprize.org)
  • And thirdly, by being able to make the separating layer independently, we are able to put this very, very thin film onto a support of our choosing. (qeprize.org)
  • The ability to make the separating layer independently means it can be made as a very thin film, making it much more permeable. (qeprize.org)
  • molecular
  • Nanowerk News ) Virginia Tech researchers announced last year that they had created a nanostructured membrane that incorporates DNA base pairs in order to impart molecular recognition and binding ability to the synthetic material. (nanowerk.com)
  • experiments
  • After a series of experiments, 4.7um membranes with- and without heat treatment in air had a final flux of 67- and 87%, relative to initial flux. (bibsys.no)
  • carbon
  • BP Magazine explores how to make a material that is 10,000 times thinner than a human hair, and looks into its potential uses in saving energy and cutting carbon emissions in industry. (qeprize.org)
  • structural
  • At a cost of $31.8 million, the 56-kilometre (35 mi) stretch of the Highway between Shackleton and Prelate was upgraded from thin membrane surface (TMS) road to a fully structural paved road designed for full regular highway traffic. (wikipedia.org)
  • Asphalt concrete pavements comprise almost 9,000 km, granular pavement almost 5,000 km, non structural or thin membrane surface TMS are close to 7,000 km and finally gravel highways make up over 5, 600 km through the province. (wikipedia.org)
  • closely
  • These transformations are reversible, as we show using cycles of expansion and compression, and closely reproduce membrane processes found in cells during area regulation. (aps.org)
  • The membrane is deep to the Recti capitis posteriores minores and Obliqui capitis superiores and is superficial to the dura mater of the vertebral canal to which it is closely associated. (wikipedia.org)
  • interaction
  • These changes may be rationalized by assuming that the interaction of amphotericin B with membrane-bound sterol resulted in the formation of aqueous pores. (rupress.org)
  • thick
  • This seemed to suggest that only one-atom-thick crystals could be used as proton conducting membranes. (arxiv.org)
  • defect
  • While many researchers strive to make graphene defect-free to exploit its superior electronic properties, Geiger's team found that graphene required the vacancies to create water channels through the membrane. (psu.edu)
  • On each side of this membrane there is a defect above the groove for the vertebral artery which serves as an opening for the entrance of the artery. (wikipedia.org)
