In this article, small scale effects on free vibration analysis of non-uniform nanobeams is discussed. Small scale effects are modelled after Eringen’s nonlocal elasticity theory while the non-uniformity is presented by exponentially varying width among the beams length with constant thickness. Analytical solution is achieved for free vibration with different boundary conditions. It is shown th...

In situ mechanical testing procedures for small scale samples in the μm range are rare. For many biological materials sizes in the μm range are typical, such as airflow sensors on crickets and individual components of the hairy attachment systems in insects and geckos (Kiel, 1998; Gorb, 2000). A variety of methods and devices exist for the mechanical testing and analysis of conventional bulk sa...

Using the combination of off-axis electron holography and environmental Transmission Electron Microscopy (TEM), an experimental setup termed 'gas holography', we investigate how presence gas in microscope affects spatial phase resolution holograms. The is introduced either by using Environmental TEM (ETEM) or a closed-cell holder. ETEM data on shows that number electrons reaching detector decre...
