Milko van der Boom is a full professor at the Weizmann Institute of Science. He completed his B.Sc. (Ing.) in Chemistry at the Amsterdam University of Applied Sciences and his M.Sc. degree in Inorganic Chemistry at the University of Amsterdam. He received his Ph.D. degree with distinction from the Weizmann Institute in 1999. He returned to Israel after three years of postdoctoral research at Northwestern University, and was appointed as a Senior Scientist in the Weizmann Institute’s Department of Organic Chemistry. His materials chemistry research focuses on metalloorganic-oriented synthetic and mechanistic studies. This research has generated considerable interest, as evidenced by several highlights in Chemical and Engineering News, Nature, and Nature Nanotechnology, and by more than 150 well-cited research articles and patents.

Prof. van der Boom's honors include an Alon Fellowship from the Israel Council for Higher Education. He received twice the Henri Gutwirth award, the Israel Chemistry Society's Prize for Excellent Young Chemists, and the Adama Prize for Technological Innovation. He is the first incumbent of the Pearlman Professional Chair. Prof. van der Boom was a member of the editorial advisory board of Organometallics, and a guest editor of the special issue “Stereochemistry of Organic Crystals” of the Israel Journal of Chemistry. He was the Chair of the Board of Studies in Chemical Sciences, the Head of the Department of Chemical Research Support, and the Head of the Department of Organic Chemistry. In addition, he was organizing the Undergraduate Summer Program. This program accepts 40 outstanding students from around the world to participate in projects in mathematics, physics, chemistry, and life sciences. Currently, he is the founding Head of the Department of Molecular Chemistry and Materials Science.

Electrodeposition in the Era of Additive Manufacturing

Abstract 

Great interest in electrodeposition has evolved in recent years in the context of additive manufacturing (AM), either for functionalization of powders for AM by common technologies such as directed energy deposition (DED) or powder bed fusion (PBF), as a post-printing finishing stage (e.g., on cellular AM’ed structures), or as a standalone three-dimensional (3D) printing technique. This presentation will review our research activities in two of the aforementioned routes. Meniscus-confined electrodeposition (MCED) of freestanding vertical pillars and overhang copper structures with submicron resolution, using an atomic force microscope and its closed-loop control [1,2], will be presented. Electrodeposition of pure and dense nanocrystalline aluminum from room-temperature ionic liquids (RTILs) on copper and nickel substrates [3] as well as electrodeposition of exceptionally well adhered CoP coatings on copper will be demonstrated. We plan to print in the near future such functional metals and alloys in our lab. Finally, I will present our novel electrochemical processing of functional core/multi-shell ZnAl/Ni/NiP powders [4,5] and core/shell ZnAl/Al₂O₃ powders [6].

Abstract

Enabling and understanding new methodologies to fabricate molecular assemblies driven by intermolecular interactions is fundamental in chemistry. Coordination chemistry can be used to control crystal growth and enables surface-confinement of molecular materials, which remains challenging. Coordination-based polymers and metal-organic frameworks (MOFs) have been explored since their discovery at the beginning of the 18^th century. Such materials are generated by the dozens in a gold-rush-type search for properties mainly related to the storage and release of energy (e.g., hydrocarbons, dihydrogen). How the molecular components, metal salts and experimental conditions control the dimensions, shapes, chirality and homogeneity of these materials is barely known. Using achiral ligands that binds late-transition metals in a defined manner, we address issues related to the mechanism underlying the formation of hollow and chiral structures. In this overview, the formation and properties of our latest materials will be discussed: chiral MOFs[1,2] the electrochromic properties of coordination-based films[3] and a solvent-free on-surface crystal-to-co-crystal conversion process.[4] This stepwise vapor-based approach offers a new strategy for the formation of hybrid supramolecular materials
