Making use of the osmotic pressure difference between fresh water and seawater is an attractive, renewable and clean way to generate power and is known as 'blue energy'(1-3). Another electrokinetic phenomenon, called the streaming potential, occurs when an ...

Probing chemical structures and physical processes with nanopores

Jiandong Feng

This thesis develops and applies the nanopore tool to probe chemical structures and physical processes at the single-molecule level: from single ions to DNA molecules. Nanopore experiments electrically measure the ionic transport through the pore and its m ...

The rise of anthropogenic global warming has sparked new interest in developing strategies to mitigate carbon dioxide emissions. Conventional carbon capture processes are not economically viable at scale due to their enormous energy cost. Membrane-based se ...

beta-Barrel pore-forming toxins (beta-PFT), a large family of bacterial toxins, are generally secreted as water-soluble monomers and can form oligomeric pores in membranes following proteolytic cleavage and interaction with cell surface receptors. Monalysi ...

What Are the Best Materials To Separate a Xenon/Krypton Mixture?

Berend Smit, Cory Matthew Simon, Rocio Mercado, Sondre Kvalvag Schnell

Accelerating progress in the discovery and deployment of advanced nanoporous materials relies on chemical insight and structure-property relationships for rational design. Because of the complexity of this problem, trial-and-error is heavily involved in th ...

Kinetics of xylem loading, membrane potential maintenance, and sensitivity of K+-permeable channels to reactive oxygen species: physiological traits that differentiate salinity tolerance between pea and barley

Amandine Massart

Salt sensitive (pea) and salt tolerant (barley) species were used to understand the physiological basis of differential salinity tolerance in crops. Pea plants were much more efficient in restoring otherwise depolarized membrane potential thereby effective ...

Robust Driving Forces for Transmembrane Helix Packing

Berend Smit

The packing structures of transmembrane helices are traditionally attributed to patterns in residues along the contact surface. In this view, besides keeping the helices confined in the membrane, the bilayer has only a minor effect on the helices structure ...

Amphiphilic vesicles are ubiquitous in living cells and industrially interesting as drug delivery vehicles. Vesicle self-assembly proceeds rapidly from nanometer to micrometer length scales and is too fast to image experimentally but too slow for molecular ...

HEATED MEMBRANES PREVENT CLOGGING OF APERTURES IN NANOSTENCIL LITHOGRAPHY

Jürgen Brugger, Andreea Veronica Savu, Shenqi Xie

We demonstrate a novel concept for nanostencil lithography with an integrated microhotplate on the stencil membrane aimed at eliminating or reducing aperture clogging during metal deposition. The stencil can be locally heated up by the embedded Pt coils to ...

Advanced Fluorescence Microscopy to Study Plasma Membrane Protein Dynamics

Joachim Piguet

Membrane protein dynamics is of great importance for living organisms. The precise localization of proteins composing a synapse on the membrane facing a nerve terminus is essential for proper functioning of the nervous system. In muscle fibers, the nicotin ...
