the natural frequency and pull-in instability of clamped-clamped nano-actuators in the presence of a dielectric layer are analyzed. the influence of the presence of casimir force, electrostatic force, fringing field effect, axial force, stretching effects and the size effect are taken into account. the governing equation of the dynamic response of the actuator is transformed in a non-dimensiona...

In order to achieve high local biological activity and reduce the risk of side effects of antibiotics in the treatment of periodontal and bone infections, a localised and temporally controlled delivery system is desirable. The aim of this research was to develop a functionalised and resorbable surface to contact soft tissues to improve the antibacterial behaviour during the first week after its...

respect to our microbial communities. The authors do the field a service by making it very clear that there is much to be learned, and that even their published book is not absolute by virtue of being the latest news. In addition, the hand-drawn illustrations are appealing and contribute to perception that far from being immortalized in official, unchangeable textbook figures, the microbiome is...
