Electron crystallography is used to study membrane proteins in the form of planar, two-dimensional (2D) crystals, or other crystalline arrays such as tubular crystals. This method has been used to determine the atomic resolution structures of bacteriorhodo ...
Since electron microscopy (EM) first appeared in the 1930s, it has held centre stage as the primary tool for the exploration of biological structure. Yet, with the recent developments of light microscopy techniques that overcome the limitations imposed by ...
Cryo-electron microscopy is a form of transmission electron microscopy that has been used to determine the 3D structure of biological specimens in the hydrated state and with high resolution. We report the development of 4D cryo-electron microscopy by inte ...
Chlorobaculum (Cba) tepidum is a green sulfur bacterium that oxidizes sulfide, elemental sulfur, and thiosulfate for photosynthetic growth. As other anoxygenic green photosynthetic bacteria, Cba tepidum synthesizes bacteriochlorophylls for the assembly of ...
A W-2Y(2)O(3) material was developed in collaboration with the Plansee Company (Austria). An ingot of the material having approximate dimension of 95 mm x 20 mm was fabricated by mixing the elemental powders followed by pressing, sintering and hot forging. ...
It is well understood that the intrinsic mechanical properties of reinforcements and second phases strongly influence those of composite materials and alloys; however, these properties are challenging to determine due to the small size and irregular shape ...
The stochastic nature of biological systems makes the study of individual cells a necessity in systems biology. Yet, handling and disruption of single cells and the analysis of the relatively low concentrations of their protein components still challenges ...
Nanocarriers, including liposomes, offer great opportunities for targeted and controlled therapy. The development in this field has led to a large panel of drug delivery systems, which can be classified into 3 different nanovector generations. However, the ...
The type Ill secretion system machinery, also known as the injectisome, delivers bacterial effector proteins into eukaryotic cells during infection. The outer membrane YscC secretin is a major part of Yersinia enterocolitica's injectisome and is among the ...
Embrittlement by helium was investigated in a lamellar TiAl alloy under two conditions: Specimens were implanted to various amounts of helium up to 762 appm at temperatures from 630 °C to 1000 °C and some of them subsequently creep-tested at the same tempe ...
