02 May 2024 Prof. Anatoly Frenkel: "Following the Dynamics of Nanoparticle Surfaces in Search of New Catalytic Pathways" Understanding mechanisms of work for a wide range of applied nanomaterials begins with identifying “active units” in operating conditions, zooming in on the “active sites” and ends with a model explaining their role for functioning of the material or device. There are two main hurdles that we are particularly interested in overcoming: 1) heterogeneity of active species and sites and 2) their dynamics that can be directly responsible for their mechanisms.

05 Jul 2023 Prof. Jeffrey D. Rimer: "New Paradigms for the Prevention of Pathological Crystallization" An efficient method to inhibit pathological crystallization is the identification of modifiers, which are (macro)molecules that reduce the rate of crystal growth. Here, I will discuss progress in understanding nonclassical pathways of crystallization and the design of effective modifiers as treatments of three human diseases: kidney stones, malaria, and atherosclerosis. One of the primary tools used to explore crystal growth mechanisms and modifier-crystal interfacial interactions is in situ atomic force microscopy, which we have coupled with microfluidics to assess modifier efficacy.

29 Mar 2023 Prof. Avinoam Zadok: "Silicon photonic integrated filters for optical and microwave frequencies" The exponential growth of data communication makes photonic integration both a necessity and a reality. Optical communication is increasingly required over shorter links, and on ever larger scales. Silicon is the favored material platform for photonics integration, due to the promise of co-integration alongside electronics and unparalleled fabrication capabilities. One of the main tasks of silicon photonics is the filtering of ultra-broadband signals, that cannot be sampled and handled directly in the optical domain.
