“If we could only know where the atoms are” (Richard Feynman)
Chemistry of nanomaterials relies, many times, on knowing the structure of a nanomaterial at the atomic scale, since at these sizes every atom matters. In my group, we study the structure-properties relationship for several systems. We aim at correlating the optical, magnetic and catalytic properties with structural motifs at the atomic scale, using mainly high resolution electron microscopy.

Research Interests
Research in the Hod Lab is focused on developing new approaches for photo-electrochemical generation of solar fuels. To do so, we use functional, highly porous hybrid organic-inorganic materials based on Metal-Organic Frameworks (MOFs), MOF composites and MOF-Derived compounds. Our research is highly interdisciplinary, combining Physical-Chemistry, Electro-Chemistry and Materials Science

Research Interests
Our group studies nanomaterials at all stages of their lifecycle, from design to application to environmental impact. These nanomaterials possess properties intermediate between bulk materials and molecules. The tunability of their properties, including optical and electrical, allow for a range of potential applications. The applications our group focuses on are catalysis and solar energy conversion from nanomaterial composite systems. As catalysts, nanomaterials could improve product selectivity, thereby reducing chemical waste and produce cleaner fuels. As energy conversion materials, they could lower the final cost per kWh to the end user. From precursor design to impact on the environment, we examine the possible contributions nanomaterials could have on our world.

Research Interests
Classical physical organic molecular descriptors, such as logP, Hammett, Taft, or Charton parameters are often used for elucidating reaction mechanisms, yet, cannot always account for the intricate molecular interactions invoked in modern synthetic chemistry. Comprehensive experimental inquiry, complemented by data-intensive physical organic analysis, can bridge this gap and enable the study and optimization of increasingly complex systems. The overarching goal of our research program is to understand structural effects at the origin of chemical reactivity, selectivity, and functionality. To this end, novel parameter systems and data analysis strategies will be applied and developed, allowing the prediction of chemical outcomes and the study of reaction mechanisms. These techniques will be employed in the context of functional organic materials as well as organo-, organometallic, and biomimetic catalytic systems. Of particular interest are chemical processes driven not by rigid covalent or dative bonds, but by weaker, non-covalent interactions. The ubiquity and diversity of such interactions provide seemingly endless approaches to rational catalyst or functional material design, yet controlling them remains an exciting challenge.

Research Interests
Autonomous motor: We constructed a bipedal autonomous DNA-motor with a coordinate activity between the two motor legs and monitored its activity using SMF techniques. The measurements are done in-situ which enables monitoring the motor’s progress and structural dynamics without disturbing its activity. Our kinetic measurements of the motor’s assembly and activity indicate that it takes dozens of seconds to complete reactions, rather than hours, if components are properly designed. However, we monitor side reactions that significantly reduce the yield of the reaction and resulting in defected motors. We are now working on implementing new strategies for motors’ preparation which will prevent side reactions, altogether, resulting in much higher yield. On the methodological side, we have measured the motor’s dynamics and its interaction with its energy source, a DNA-fuel, in equilibrium and non-equilibrium conditions. Our work demonstrates that by using SMF, one can construct a DNA-machine and monitor its activity in ways not possible with conventional methods. We demonstrate that our methods enable simultaneous in-situ monitoring of the motors efficiency, integrity and activity
