Plasmonic nanoparticles are particularly interesting as they are strongly absorbing in the near infrared (NIR) regime and their associated temperature increase is sensitively dependent on the shape and composition of the structure and on the wavelength of light. Therefore, much effort is put into synthesizing novel nanostructures for optimized interaction with incident light in the NIR regime which has a relatively long penetration depth into biological tissue.

Cold Sintering involves a transient phase that permits the densification of particulate materials at low temperatures 300^oC and below. Sintering at such low temperature offers so many new opportunities. It permits the integration of metastable materials that would typically decompose at high temperatures. So cold sinter enables a platform for better unification of material science. Now ceramics, metal and polymers can be processed under a common platform in one step processes. With controlling the forming process new nanocomposites can be fabricated.

Due to their high specific strength, carbon and glass fiber reinforced composites find wide applications as lightweight and high strength materials, for aerospace and automotive applications. However, these composite materials are extremely sensitive to relatively low velocity, and localized impact loads leading to damage in the through thickness direction. The mechanical damage induces delamination (separation cracks) at the boundary between plies. Delamination due to crack growth is one of the most prevalent life-limiting factors of a composite.

Materials prediction is the ultimate solution for ending blind experimental search within an
expansive material parameter space. First-principles theory entirely based on quantum mechanics
without prior input parameters is the perfect tool for new material design. In order to predict exotic
quantum materials and out-of-equilibrium processes, many-body physics and quantum kinetic theory are
needed to bridge with first-principles methods.
