DESCRIPTION:Dr. Guido Panzarasa ETH Zürich\nThe aim of this talk is to gi
 ve an overview of recent results in the fields of clock reaction-controlle
 d self-assembly and functional wood materials. Although conceptually very 
 different\, these two topics help highlight the relevance of temporal prog
 ramming in materials science from two opposite sides – fundamental and n
 ano-scale vs. real-world and global-scale.\nThe design of artificial chemi
 cally-controlled dissipative self-assembly systems is a very promising app
 roach for the production of life-mimicking active materials.\nIt is tantal
 izing to image materials that could autonomously self-assemble from buildi
 ng blocks\, perform their function(s)\, and afterwards disassemble back in
 to the starting building blocks ready to start a new cycle. In such system
 s\, external control could be avoided or reduced to a minimum through the 
 use of nonlinear chemical reaction networks. In this framework clock react
 ions are especially useful tools\, e.g. as in situ generators of chemical 
 (pH\, redox) and physical (temperature) stimuli for the time-programming o
 f self-(dis)assembly events in (supra)molecular and colloidal systems.\nWo
 od is a renewable resource as well as a natural sink for CO2. Its availabi
 lity\, unique (micro)structure and mechanical properties make it a state-o
 f-art building material. To further promote its use in sustainable smart b
 uildings\, it is necessary to enable it with new functions – such as the
  ability to generate and conduct electricity and light. These composites h
 ave great applicative potential and\, when designed and produced according
  to circular economy and green chemistry principles\, could offer an advan
 tage for alleviating the effects of global climate change.\n\nBio: Guido P
 anzarasa received his PhD in Chemical Sciences in 2016 from the University
  of Eastern Piedmont “Amedeo Avogadro” (Italy). In 2018 he joined ETH 
 Zürich as a postdoc in Prof. Eric Dufresne’s group (Department of Mater
 ials)\, where he started to explore the synergies between systems chemistr
 y and materials science aiming to develop chemically-programmable life-mim
 icking materials. In 2020 he was promoted group leader in the Wood Materia
 ls Science Laboratory (Prof. Ingo Burgert\, Department of Civil\, Environm
 ental and Geomatic Engineering) and his research focus drifted towards sus
 tainability\, green chemistry and functional wood materials.\n
