High Resolution Helium Ion Scanning Microscopy of the Rat Kidney
Helium ion scanning microscopy is a novel imaging technology with the potential to provide sub-nanometer resolution images of uncoated biological tissues. So far, however, it has been used mainly in materials science applications. Here, we took advantage of helium ion microscopy to explore the epithelium of the rat kidney with unsurpassed image quality and detail. In addition, we evaluated diff...
متن کاملAn extended dynamical hydration shell around proteins.
The focus in protein folding has been very much on the protein backbone and sidechains. However, hydration waters make comparable contributions to the structure and energy of proteins. The coupling between fast hydration dynamics and protein dynamics is considered to play an important role in protein folding. Fundamental questions of protein hydration include, how far out into the solvent does ...
متن کاملHigh-resolution thermal expansion measurements under helium-gas pressure.
We report on the realization of a capacitive dilatometer, designed for high-resolution measurements of length changes of a material for temperatures 1.4 K ≤ T ≤ 300 K and hydrostatic pressure P ≤ 250 MPa. Helium ((4)He) is used as a pressure-transmitting medium, ensuring hydrostatic-pressure conditions. Special emphasis has been given to guarantee, to a good approximation, constant-pressure con...
متن کاملHigh-resolution Imaging of the Dust Disk around 49 Ceti
Subarcsecond scale Keck images of the youngA1V star, 49 Ceti, resolve emission at k 1⁄4 12:5 and 17.9 m from a disk with long axis at position angle (P.A.) 125 10 and inclination 1⁄4 60 15 . At 17.9 m, the emission is brighter andmore extended toward the northwest (NW) than the southeast (SE).Modeling of themid-infrared images combined with flux densities from the literature indicate that the b...
متن کاملHigh Sample Rate Optically Pumped Helium Magnetometer
Optically pumped helium magnetometers are important instruments whichhave many applications in military, mass spectroscopy and space applications. In thispaper, the working principles of helium magnetometers have been explained. There isalso an introduction of a new method for finding the resonant frequency, which hasadvantages to the typical method such as more sample r...
