Using fluorescence fluctuation spectroscopy to quantify molecular dynamics within cells
Microscopy techniques like fluorescence correlation spectroscopy (FCS) and number and brightness analysis (N&B) allow to quantify concentrations, diffusion rates, and oligomerization of fluorescently labeled molecules in the living cell. In this protocol the principles of how to set up these types of experiments are described including calibration ...

Characterization of the key membrane protein cytochrome Cyc2 from Ghiorsea bivora
This study reports the first detailed biochemical analysis of Cyc2TAG1_1, a cytochrome protein involved in microbial iron oxidation. We produced and purified this enzyme in E. coli, then measured its iron‐oxidizing efficiency, and characterized its electrical and structural properties.

ErB4 and NdB4 nanostructured powders are produced by mechanochemical synthesis. 5 h mechanical alloying and 4 M HCl acid leaching are used in the production. ErB4 and NdB4 powders exhibit maximum magnetization of 0.4726 emu g−1 accompanied with an antiferromagnetic‐to‐paramagnetic phase transition at about TN = 18 K and 0.132 emu g−1 with a maximum at ...

Measurement of the radon and thoron exhalation rates from the water surface of Yixin lake
The importance of determining the radon exhalation rate from water surface is emphasized by the increased use of radon and its daughter products as tracers in large-scale circulation studies of the atmosphere.

Triggering volcanic eruptions by gas bubbles accumulations in the magma chamber
Abstract. We present a model for volcanic eruptions in open-conduit condition based on the transport of batches of magma driven by the accumulation of bubbles. The viscosity of the surrounding magma counteracts gravity; however, the primary upward force acting on these bodies is driven by gas vesicles which accumulate beneath the denser bodies.
