Researchers use computer simulations to discover distinct physics of atomized droplet impact on dry surfaces at the microscopic level, improving understanding needed for spray cooling, inkjet printing and coating.
A novel nanoparticle system can specifically interact with adhesin molecules of a specific E. coli strain and cause agglutination through nanoparticle-bacteria complex. Applying treatment with an alternating magnetic field to such complex caused significant reduction in viability of the targeted bacteria.
Scientists have developed a method with which they can measure the contact area between a bacterium and the surface it is 'sitting' on. Interestingly a large contact area does not necessarily mean a large adhesive force.
