An analytical expression for the diffusion current in organic metal-insulator-metal diodes is derived. Summing with the classical space-charge limited current provides a full analytic description of the current as a function of voltage, temperature and layer thickness.
Nearly all concepts of nanocarriers as drug delivery devices rely on intracellular uptake. Instead, we demonstrate an alternative concept for rapid and specific delivery of cargo by nanoparticles to lipid droplets. The model can serve as a novel strategy for the non-invasive delivery of drugs by releasing hydrophobic cargo, in our case a model dye, through a kiss-and-run mechanism between nanoparticle and cell membrane.
In the course of evolution a large variety of highly specialized reversible adhesive pads have developed, enabling many animals mobility in all kinds of living environment. A simple procedure was developed to produce a magnetically controllable bio-inspired adhesive system. It is composed of elastic, magnetic micro-columns which can be turned on and off by a magnetic field and enable adhesion under dry and wet conditions.
Chemical functionalization is one of the most powerful and widely used strategies to control the properties of nanomaterials, particularly in the field of graphene. Here we present a general edge chlorination protocol for atomically precise functionalization of nanographenes at different scales and its application in graphene nanoribbons.
Here, we present the formation of novel functional colloidal monolayers with photoswitchable fluorescence. Colloids containing an appropriate dye system can serve as individual pixels for optical data storage or light erasable barcoding.br>
The relaxation of vibrationally excited OH groups water at interfaces occurs in a manner fundamentally different from water in bulk. Two distinct pathways – both not present in bulk – are responsible for fast, sub-picosecond relaxation. These insights are relevant for e.g. the many atmospheric chemical processes occurring on water and ice surface.
