Structure of the crystallins [PDF]

open access: yesEye, 1999
The lens is formed from two protein superfamilies, the alpha- and beta gamma-crystallins. Representative three-dimensional structures show they both have a basic 2-beta-sheet domain fold, with the beta gamma-domain being made from two intercalating Greek keys.

Nano Scaled Checkerboards: A Long Range Ordering in NiCoMnAl Magnetic Shape Memory Alloy Thin Films with Martensitic Intercalations

open access: yesApplied Sciences, 2022
Magnetic shape memory Heusler alloys, such as NiCoMnAl, are considered as promising candidates for magnetocaloric cooling applications. Grown in thin film systems of adjacent layers with austenite and martensite crystal structures of almost equal ...

Crystalline Amyloid Structures at Interfaces [PDF]

open access: yesAngewandte Chemie International Edition, 2009
AbstractLaying the groundwork: The interfacial self‐assembly properties of an amyloid peptide were used to develop crystalline nanostructures at air–water interfaces, which were studied by both AFM microscopy and X‐ray diffraction (see image). These structures generate regular arrays of functional groups and pave the way to controlled deposition of ...

Improving the Photocatalytic Properties of TiO2 Coatings by Modification of the Pore Size and the Crystalline Structure by Combining Anodization and MAO Technology

open access: yesInternational Journal of Electrochemical Science, 2021
A TiO2 coating with regular pore parameters was fabricated on the surface of pure titanium metal. The pore size and crystalline structure of the coating were modified by combining anodizing and micro arc oxidation technology.

The structural language of crystalline polymers* [PDF]

open access: yesPolymer Engineering & Science, 2021
AbstractIn sharp contrast with their amorphous counterparts, crystalline polymers provide a wealth of information on their chain conformation, the packing of the chains in unit‐cells, the existence or not of mirror symmetric conformations, on the crystalline lamellae, on the folds linking the crystalline stems, and so forth.
