Abstract Hydrophilic polymer coatings on artificial implants generate excellent tribological properties. The friction properties of are affected by salt ion factors. Herein, the atomic force microscopy (AFM) was used to show that superlubricity achieved between poly(vinylphosphonic acid) (PVPA)-modified Ti6Al4V and polystyrene (PS) microsphere probe lubricated with monovalent solutions (LiCl, N...

The application range of superlubricity systems can be extended effectively by realizing an adjustable friction coefficient. In this study, a stable poly(vinylphosphonic acid) (PVPA) system was developed using sodium chloride (NaCl) solution as the lubricant. A sudden increase in coefficient occurred when trivalent salt introduced to base lubricant during process. changes surface microstructure...

Pathogenicity and presentation of Mycoplasma gallisepticum (MG) infection may differ from one strain to another and this may have implications on control measures. Infection of individual birds with more than one MG strain has been reported. A PCR followed by high resolution melt (HRM) curve analysis has been developed in our laboratory and routinely used for detection and differentiation of MG...
