TL;DR: In this article, the design of an ultrasonically vibrated tool holder and the experimental investigation of ultrasonic assisted drilling of Inconel 738-LC was presented, where the circularity, cylindricity, surface roughness and hole oversize were measured and compared.

TL;DR: In this article, a distributed parameter model is used to study the pull-in instability of cantilever type nanomechanical switches subjected to intermolecular and electrostatic forces.

TL;DR: In this article, the most commonly used label-free microfluidic-based cell separation methods are described and the challenges and perspectives to further develop such methods are discussed, as well as computational approaches complementing such methods.

TL;DR: In this paper, the effect of imposition of ultrasonic vibration on the grinding of Ti6Al4V alloy is studied, and machining forces and surface roughness are compared between conventional grinding (CG) and ultrasonic assisted grinding (UAG) processes.

TL;DR: In this paper, the governing differential equation and boundary conditions of strain gradient microbar were derived using variational approach and a closed-form analytical solution was obtained for static torsion and the characteristic equation, which gives the natural frequencies, was derived and analytically solved for the free torsional vibrations of the strain-gradient microbar.
