EVERYTHING SLIPS—Design of Novel Non-fouling Materials

"for developing new synthesis routes inspired by biological principles for the fabrication of advanced complex multifunctional materials and devices"

Liquids entrapped within and on a solid begin to exhibit unique behaviors often providing the surrounding material with unprecedented properties. Recently we introduced a new technology to create self-healing, antifouling coatings (so-called Slippery, Lubricant-Infused Porous Surfaces, or SLIPS), which has given rise to a fast-developing area of materials research. These bioinspired coatings that mimic slippery surfaces of a pitcher plant outperform state-of-the-art materials in their ability to resist ice and microbial adhesion, repel various simple and complex liquids, prevent marine fouling, or reduce drag. Generalized design principles for creating stable, shear-tolerant SLIPS on glass, ceramics, polymers, fabrics and metals, as well as their performance in condensers, heat exchangers, membranes and medical devices will be discussed.  We anticipate that slippery surfaces can find important applications as antifouling materials in medicine, construction, naval and aircraft industries, fluid handling and transportation, optical sensing, and as antifouling surfaces against highly contaminating media operating in extreme environments.

Towards Affordable and Sustainable Use of Noble-Metal Nanocrystals in Catalysis and Nanomedicine

"for seminal contributions to shape-controlled synthesis of metal nanocrystals with major impact on catalysis, plasmonics and biomedicine"

Noble metals represent some of the least abundant elements in the Earth’s crust. There is an urgent need to maximize the utilization efficiency of noble metals and thus attain affordable and sustainable products. One approach is based on the development of hollow nanocrystals with well-defined and controllable facets while their walls are kept below five atomic layers (or 1 nm) in thickness. In this talk, Xia will start with a brief introduction to two methods that have been developed for the production of such nanomaterials, with the first involving layer-by-layer atomic deposition followed by etching and the second involving galvanic replacement with a sacrificial template. He will then showcase some remarkable properties and applications of this novel class of nanomaterials, including their use as cost-effective catalysts for energy conversion, as carriers for controlled release and drug delivery and as theranostic agents for cancer medicine. Finally, he will discuss some barriers to the commercialization of these nanomaterials.
