Cryo, Cryo-etch and Tandem Cryo-HRSEM Correlated with Cryo-STEM of Elastin-Mimetic Block Copolymers

The Tesla Cryo-plants

The Tera-eV Energy Superconducting Linear Accelerator (TESLA) is a 32 km long superconducting linear electron/positron collider of 500 GeV centre of mass energy (upgradeable to 800 GeV), presently in the planning phase at DESY [1,2]. About 21000 superconducting RF 9-cell cavities have to be cooled with superfluid helium at 2 K. The cavities are assembled in groups of 12 into about 16 m long cry...

Cohomology of Cryo-Electron Microscopy

The goal of cryo-electron microscopy (EM) is to reconstruct the 3-dimensional structure of a molecule from a collection of its 2-dimensional projected images. In this paper, we show that the basic premise of cryo-EM—patching together 2-dimensional projections to reconstruct a 3-dimensional object—is naturally one of Čech cohomology with SO(2)-coefficients. We deduce that every cryoEM reconstruc...

Investigation of Escherichia coli Selenocysteine Synthase (SelA) Complex Formation Using Cryo-Electron Microscopy (Cryo-EM)

Incorporation of selenocysteine (Sec U) into proteins is directed by a in-frame UGA codon in all domains of life. In Bacteria, Sec biosynthesis and incorporation involves the interaction of Selenocysteine Synthase (SelA), tRNA (SelC or tRNA Sec ), Selenophosphate Synthetase (SPS), a specific elongation factor known as SelB and the specific mRNA structure SElenocysteine Insertion Sequence (SECIS...
