Aqueous Lubrication : Natural and Biomimetic Approaches by Nicholas Spencer

By Nicholas Spencer

Guy lubricates regularly with oil. Nature lubricates solely with water. natural water is a terrible lubricant, however the addition of proteins, specifically glycoproteins, can adjust surfaces to cause them to way more lubricating at gradual speeds. figuring out how nature does this, and the actual constructions concerned, isn't just very important for the certainty of illnesses corresponding to osteoarthritis, but additionally crucial for the profitable software of articulating implants, comparable to hips and knees, in addition to the improvement of scientific units similar to catheters and make contact with lenses. a number of significant purposes of water-based lubrication are already in position within the own care and foodstuff industries, and extra business purposes of water-based lubrication may have an important optimistic influence at the surroundings.

This booklet is the 1st of its style. It brings jointly the newest learn in organic and biomimetic, water-based lubrication and is authored through the world's specialists within the box.

Loadings in Thermal Barrier Coatings of Jet Engine Turbine Blades: An Experimental Research and Numerical Modeling

This ebook discusses complicated loadings of turbine blades and protecting layer Thermal Barrier Coating (TBC), less than genuine operating plane jet stipulations. They obey either multi-axial mechanical loading and unexpected temperature version in the course of beginning and touchdown of the airplanes. specifically, sorts of blades are analyzed: desk bound and rotating, that are greatly utilized in turbine engines produced by way of plane factories.

Introduction Mucosa lines internal organ tissues and body cavities and plays a protective role by secreting slimy and adherent mucus layers. 1−3 As shown in the Fig. 1, mucin is large-molecularweight glycoprotein, constructed from a linear protein backbone with heavy glycosylation of the central part in a tandem pattern. Carbohydrate chains account for 70–80% of the molecular weight of mucin and impart the hygroscopic nature to mucus gels.
