Preparation and investigation of structure, magnetic and dielectric properties of (BaFe11.9Al0.1O19)1-x (BaTiO3)x bicomponent ceramics

(BaFe11.9Al0.1O19)1-x (BaTiO3)x with x = 0, 0.25, 0.5, 0.75 and 1 bicomponent ceramics has been prepared from single-phase compounds of BaFe11.9Al0.1O19 (x=0) (BFO) and BaTiO3 (x=1) (BTO) by a standard...

2D polarization imaging as a low-cost fluorescence method to detect α-synuclein aggregation ex vivo in models of Parkinson’s disease

A hallmark of Parkinson’s disease is the formation of large protein-rich aggregates in neurons, where α-synuclein is the most abundant protein. A standard approach to visualize aggregation is fluorescence...

Macroscopic Quantum Electrodynamic and (Time-Dependent) Density Functional Theory Approaches to Electronic Ground and Excited State Dispersion Interactions between Fullerenes.

Coreless SQUID-based cryogenic current comparator for non-destructive intensity diagnostics of charged particle beams

We report on a novel concept and prototype development of a coreless non-destructive SQUID-based charged particle beam monitor for accelerator facilities. Omitting the typically used pickup coil with high...

Controlling the energy gap of a tunable two-level system by ac drive

We study the influence of a strong off-resonant driving signal to the energy levels of a superconducting flux qubit both experimentally and theoretically. In the experiment, we carry out a three-tone spectroscopy....

Sources of heading error of optically pumped magnetometers operated in the Earth magnetic field

When optical pumped magnetometers are aimed for the use in Earth magnetic field the orientation of the sensor to the field direction is of special importance to achieve accurate measurement result. Inaccuracy...

FRET-enhanced photostability allows improved single-molecule tracking of proteins and protein complexes in live mammalian cells

A major challenge in single-molecule imaging is tracking the dynamics of proteins or complexes for long periods of time in the dense environments found in living cells. Here, we introduce the concept of...

How to minimize dye-induced perturbations while studying biomembrane structure and dynamics: PEG linkers as a rational alternative

Organic dye-tagged lipid analogs are essential for many fluorescence-based investigations of complex membrane structures, especially when using advanced microscopy approaches. However, lipid analogs may...

Nanoparticles Can Wrap Epithelial Cell Membranes and Relocate Them Across the Epithelial Cell Layer

Although the link between the inhalation of nanoparticles and cardiovascular disease is well established, the causal pathway between nanoparticle exposure and increased activity of blood coagulation factors...

From Dynamics to Membrane Organization: Experimental Breakthroughs Occasion a “Modeling Manifesto”

New experimental techniques reveal the plasma membrane to be heterogeneous and "scale-rich," from nanometers to microns, and from microseconds to seconds. This is critical information, as heterogeneous,...
