Project Thermal Transport
Contact: Prof. Dr. Markus Retsch
Thermal transport in nano- and mesostructured materials plays an important role in many technological applications. Efficient insulation as well as efficient heat dissipation are in the central focus of a lot of current research efforts. ...more
Project VISIRday
Contact: Prof. Dr. Markus Retsch
Cooling is a key technology of our modern life. A device capable of efficient sub-ambient daytime cooling without the need for an external power input would considerably lower our overall energy consumption. Nature offers a chance to off-load heat directly into the cold outer space via the so-called “sky window” ...more
Project Plasmonics
Contact: Prof. Dr. Markus Retsch
Interaction of light with nanostructured objects consisting of noble metals such as Au or Ag leads to an oszillation of electrons in the conduction band. At the resonance frequency most of the incident light is absorbed by this resonator, which dimensions are typically smaller than the wavelength of light. ...more
Project Self-assembly
Contact: Prof. Dr. Markus Retsch
Self-assembly of monodisperse colloidal particles readily leads to well-defined nanostructured materials. Such systems can be used to fabricate hierarchically structured hybrid materials or they can be used as templating mask, for instance for nanosphere lithography. ...more
Project PhoXonics
Contact: Prof. Dr. Markus Retsch
Color by structure is a widely known phenomena and can be found in the bright iridescent colors of opals and butterfly wings. This bright color derives from a strict and well-defined undulation of the refractive index of a given material. Several synthetic approaches have been undertaken over the past decades to mimic this intriguing coloration mechanism. ...more
Project Mechanics
Contact: Prof. Dr. Markus Retsch
Granular materials feature very intriguing mechanical properties, which differ vastly from their solid bulk materials. An everyday example of granular mechanics can be inferred from ground coffee powder. ...more
