Universal Tool for Single-Photon Circuits: Quantum Router Design

We demonstrate that the non-Hermitian Hamiltonian approach can be used as a universal tool to design and describe a performance of single photon quantum electrodynamical circuits (cQED). As an example...

Background reduction in STED-FCS using coherent-hybrid STED

Fluorescence correlation spectroscopy (FCS) is a valuable tool to study the molecular dynamics of living cells. When used together with a super-resolution stimulated emission depletion (STED) microscope,...

z-STED imaging and spectroscopy to investigate nanoscale membrane structure and dynamics

Super-resolution STED microcopy provides optical resolution beyond the diffraction limit. The resolution can be increased laterally (xy/2D) or axially (z/3D). 2D STED has been extensively used to elucidate...

The cortical actin network regulates avidity-dependent binding of hyaluronan by the Lymphatic Vessel Endothelial receptor LYVE-1

Lymphatic vessel endothelial hyaluronan receptor 1 (LYVE-1) mediates the docking and entry of dendritic cells to lymphatic vessels through selective adhesion to its ligand hyaluronan in the leucocyte surface...

High photon count rates improve the quality of super-resolution fluorescence fluctuation spectroscopy

Probing the diffusion of molecules has become a routine measurement across the life sciences, chemistry and physics. It provides valuable insights into reaction dynamics, oligomerisation, molecular (re-)organisation...

Sodium Ion Conductivity in Superionic IL-Impregnated Metal-Organic Frameworks: Enhancing Stability Through Structural Disorder

Metal-organic frameworks (MOFs) are intriguing host materials in composite electrolytes due to their ability for tailoring host-guest interactions by chemical tuning of the MOF backbone. Here, we introduce...

Laser-induced spatially-selective tailoring of high-index dielectric metasurfaces

Optically resonant high-index dielectric metasurfaces featuring Mie-type electric and magnetic resonances are usually fabricated by means of planar technologies, which limit the degrees of freedom in tunability...

Tracking and analysing the Brownian motion of nano-objects inside hollow core fibers

Tracking and analysing the individual diffusion of nanoscale objects such as proteins and viruses is an important methodology in life science. Here, we show a sensor that combines the efficiency of light...

Chemical Treatment of Graphene Films to Improve Electrical Conductivity

Improved retention of nonvolatile bipolar BiFeO3 resistive memories validated by memristance measurements

The transport properties of metal-insulator-metal (MIM) capacitor-like structures have been demonstrated to be sensitive to the metal-insulator interface. BiFeO3 thin films have been grown on Pt/Ti/SiO2/Si...
