A novel interfacial polymerization assisted phase inversion process for the facile fabrication of ion-selective nanofiltration membranes
Zongyao Zhou, Tao Liu, Shijie Hu
Interfacial polymerization (IP) and non-solvent induced phase inversion (NIPS) are the two most commonly used mainstream technologies to fabricate separation membranes. Taking their advantages, we developed a simple, facile and scalable method to integrate ...
Lausanne2023High throughput wide field second harmonic imaging of giant unilamellar vesicles
Sylvie Roke, Maksim Eremchev, David Roesel, Pierre-Marc Jean Marie Dansette
Cell-sized giant unilamellar vesicles (GUVs) are an ideal tool for understanding lipid membrane structure and properties. Label-free spatiotemporal images of their membrane potential and structure would greatly aid the quantitative understanding of membran ...
AIP Publishing2023Structure of a membrane-bound menaquinol:organohalide oxidoreductase
Christof Holliger, Henning Paul-Julius Stahlberg, Julien Maillard, Dongchun Ni, Lorenzo Cimmino
Organohalide-respiring bacteria are key organisms for the bioremediation of soils and aquifers contaminated with halogenated organic compounds. The major players in this process are respiratory reductive dehalogenases, corrinoid enzymes that use organohali ...
2023Rheological Properties of Ionically Crosslinked Viscoelastic 2D Films vs. Corresponding 3D Bulk Hydrogels
Esther Amstad, Gaia De Angelis
Ionically crosslinked hydrogels containing metal coordination motifs have piqued the interest of researchers in recent decades due to their self-healing and adhesive properties. In particular, catechol-functionalized bulk hydrogels have received a lot of a ...
AMER CHEMICAL SOC2023Development of a numerical model to assess the influence of fluid-structure interactions on the dynamic behavior of geomembrane systems in pressure waterways
The need to maintain and expand hydraulic structures is a major challenge for the coming energy transition, especially in Western countries. One technique already widespread allowing to meet these issues consists in the use of geomembranes to overcome prob ...
2023Simultaneous Electrophysiology and Imaging Reveal Changes in Lipid Membrane Thickness and Tension upon Uptake of Amphiphilic Gold Nanoparticles
Francesco Stellacci, Paulo Henrique Jacob Silva, Xufeng Xu, Camilla Servidio
Amphiphilic gold core nanoparticles (AmNPs) striped with hydrophilic 11-mercapto-1-undecanesulfonate (MUS) and hydrophobic 1-octanethiol (OT) ligands are promising candidates for drug carriers that passively and nondisruptively enter cells. Yet, how they i ...
Washington2023Effects of thermal, mechanical, and electrostatic perturbations on lipid membrane hydration investigated by second harmonic imaging
Hydrated lipid bilayer membranes are crucial components of cells and organelles, serving as the outer boundary that separates the cellular components from the extracellular environment. Lipid membranes regulate their structures and functions by dynamically ...
EPFL2023Fabrication of ZIF-8 membranes by direct assembly of nanosheets from bottom-up synthesis growth solution
Kumar Varoon Agrawal, Xuekui Duan, Heng-Yu Chi
Metal-organic frameworks (MOFs) host intrinsically porous structure and rich structural and chemical features. Several MOFs with pore aperture comparable to the size of gas molecules have attracted interest to form the selective layer of membranes. Synthes ...
ELSEVIER2023Mechanisms Underlying the Recruitment of Inhibitory Interneurons in Fictive Swimming in Developing Xenopus laevis Tadpoles
Developing spinal circuits generate patterned motor outputs while many neurons with high membrane resistances are still maturing. In the spinal cord of hatchling frog tadpoles of unknown sex, we found that the firing reliability in swimming of inhibitory i ...
SOC NEUROSCIENCE2023Structure and regulation of the myotonic dystrophy kinase-related Cdc42-binding kinase
Charlotte Julie Caroline Gehin
Protein kinases of the dystonia myotonica protein kinase (DMPK) family are critical regulators of actomyosin contractility in cells. The DMPK kinase MRCK1 is required for the activation of myosin, leading to the develop-ment of cortical tension, apical con ...
