Using a novel X-ray microcrystallography technique the atomic crystal structure of the cross-β spine of a seven-residue peptide was determined. It was found to be a double β-sheet, where the opposing sheets form an extremely close, zipper-like, match and are stabilized by non-hydrogen inte...
A second and less trivial answer is that the protein structure of developing life adapted itself to the temperature by which it was surrounded. Had it adapted itself over the space of a billion years to liquid ammonia temperatures, protein structures might have been evolved that would be far to...

I have a future blog planned on airships, because they’re awesome. Let’s rebuild the Hindenburg but with mylar, nylon, carbon fiber, and helium. We can put a thousand people on it. It will be slow, crowded, and a human petri dish, just like a cruise ship. It will also be peri...
(CH2)6NH– during this MLD nylon process are much larger than the atomic layers of –Al– and –O– in the ALD–Al2O3. This underlies the higher GPC of the MLD nylon process of AC–HD. Additionally, many more pure polymeric materialsviaMLD recently have been summarized in the ...
Synthesis and characterization of nanostructured-segmented block copolyetheramide based on nylon6 and poly(ethylene oxide) Segmented block copolymer based on nylon6(N6) and polyethylene oxide(PEO) with stochiometric ratio was synthesized via a two-step process.The first step re... M Peyravi,MA ...
This material series is featured by the crystal-amorphicity duality induced by the large anionic size mismatch: a crystalline sublattice of highly size-mismatched anions Te/S coexists with an amorphous-like sublattice of cations Cu/Ag. In the context of structure-property correlation, the crystal...
Numerous attempts were undertaken to collect single-crystal X-ray diffraction data of reasonable quality for structure refinement and hydrogen localization. These are because alunogen crystals are thin, maybe intergrown, twinned or low-crystalline. A photograph of the crystal on a nylon loop was take...
Figure 1. Configuration of the setup: (A) Internal structure diagram of SERF AM. (B) A five-layer magnetic shield was employed. Both the grating and the silica aerogel pad are made of non-magnetic materials. The thickness of the silica aerogel pad is 2 mm. During the measurement, AM1AM...
