Metal-insulator-metal (MIM) diodes are very promising for application as rectennas for solar energy harvesting, photo-detectors and high frequency mixers. Good MIM diode performance requires a high asymmetry, a strong nonlinearity, a large responsively, as well as a low resistance or a high on-current. These figures of merit are mainly determined by the work function difference of the electrodes, and the barrier height between the insulator and the electrode materials. In the design of MIM diodes, ...

Reversible adhesion can be used to transfer or to manipulate objects. Especially if the objects are small and/or fragile their manipulation become very challenging. Intermolecular forces such as Van-der-Waals can be used to achieve a strong adhesion between the objects. Moreover, surface functionalization and the creation of nano- and microstructures can be used to improve these adhesion properties. Unfortunately, the adhesion becomes insufficient if the surfaces are wet or rough. Another problems ...

The cellular identity of mature cells that are confined in a specialized genetic expression profile can be overcome by introducing just a few genes that encode for so-called reprogramming factors [1]. By means of this intervention, also known as reprogramming, the cells then become pluripotent and represent induced pluripotent stem cells (iPS cells) [1]. Nowadays, numerous new cell culture models have been established based on reprogramming protocols that yield iPS cells. Such cell culture models ...

The RNA-programmable DNA-endonuclease Cas9 is widely used for genome engineering, where a high degree of specificity is required. Though this is a mechanism well controlled by canonical base-pairing, there is evidence that Cas9 does accept mismatches under certain circumstances.
