Guy lubricates in most cases with oil. Nature lubricates solely with water. natural water is a terrible lubricant, however the addition of proteins, in particular glycoproteins, can alter surfaces to cause them to way more lubricating at sluggish speeds. realizing how nature does this, and the actual buildings concerned, is not just vital for the certainty of illnesses resembling osteoarthritis, but additionally crucial for the profitable software of articulating implants, resembling hips and knees, in addition to the improvement of scientific units reminiscent of catheters and phone lenses. a bunch of significant functions of water-based lubrication are already in position within the own care and nutrients industries, and extra business purposes of water-based lubrication can have an important confident effect at the setting.
This booklet is the 1st of its sort. It brings jointly the most recent learn in organic and biomimetic, water-based lubrication and is authored by way of the world's specialists within the box.

15 M NaCl,42 revealed that both parameters signiﬁcantly inﬂuence the surface adsorption and surface forces of BSM; the interaction in low BSM concentration and low-salt buﬀer is characterized by long-range attractive forces caused by bridging, hysteresis between compression/decompression cycles, and exponential, repulsive steric interaction. 15 M NaCl solution is used in addition. 44 have conﬁrmed a few common features for the surface forces between BSM layers on mica. Firstly, DLVO theory cannot fully explain the repulsive regime, and repulsion is attributed primarily to steric eﬀects.
