Transporter bridges

A group in England has developed a very nice idea based on fluctuations [31] here a molecule is chemisorbed on one end to a surface, and a conductive scanning tip is brought to within about a molecule length from the supporting metal. Thermal excitation then permits molecules to form instantaneous transport bridge structures between the planar support and the conductive electrode - one observes fluctuations... 

In several cases of interest in photoconversion devices, the species D or A to be oxidised or reduced at the electrode is not in close contact with the electrode surface, but deliberately separated from it by a short distance. The separator may be, for example, a thin passivating film, a molecular spacer layer or an electron-transporting bridge B in an electrode-B-A or electrode-B-D assembly such as a self-assembled monolayer (SAM).

The advent of a portable source of very high energy x-rays has opened up x-ray inspection possibilities in a wide range of environments. Applications include such fields as nuclear waste containers, bridges, nuclear and fossil power plants, surface and airborne transportation systems, space launch systems and other thick section NDT and other inspection problems that cannot be solved imaged using other NDT methods. 

Within each sarcomere the relative sliding of thick and thin filaments is brought about by "cross-bridges," parts of the myosin molecules that stick out from the myosin filaments and interact cyclically with the thin actin filaments, transporting them hy a kind of rowing action. During this process, the hydrolysis of ATP to ADP and phosphate couples the conformational... 

Its best use is for bridges, gantries, conveyor-belt steelwork, etc., where the relatively drab, matte appearance can be tolerated. The Department of Transport uses this material on inland motorway bridges, and has found that, if applied to a correctly prepared and primed surface, it can be substantially maintenance-free for 20 years.
