BIGS Chemistry Lecture: Prof. Dr. Lars Borchardt
Prof. Dr. Lars Borchardt, Ruhr-University Bochum A Milling Ball as Catalyst – The Novel Concept of Direct Mechanocatalysis Direct mechanocatalysis is a novel concept of catalysis neither utilizing light, thermal heating nor an electric potential as in conventional catalysis, but simply mechanical energy. In this mechanochemical approach, mechanical energy is provided by the collision of milling balls inside a ball mill. The catalyst is neither dissolved (as in homogenous catalysis), nor a powder or bed of shaped bodies (as in heterogeneous catalysis), but the milling ball itself. Even in the absence of any solvent, solid reactants can be brought into reactions mechanocatalytically - only using milling balls that refresh their catalytically active surface constantly during their continuous collisions.

BIGS Chemistry Lecture: Dr. Maximilian Menche
Dr. Maximilian Menche, BASF, Ludwigshafen Quantum Chemistry @ BASF and How Volunteering Got Me There Quantum chemistry has become a standard tool in chemistry research over the past decades due to the continuous development of methods, algorithms, computational resources and the general insights the methods can provide. The chemical industry has also contributed to this development and is continuously making use of this access to large-scale screening methodologies or detailed insights into reaction mechanisms. In the first part of this talk, I will present several examples of how quantum chemistry is applied to support and accelerate research efforts at BASF, showcasing its impact on innovation and discovery. The second part of the talk will switch gears to highlight volunteering in scientific societies, local communities and international networks, which remains an important pillar of these networks.

Organic Chemistry Seminars: Prof. Dr. Alicia Casitas
Prof. Dr. Alicia Casitas, University of Marburg An organometallic perspective to first-row transition metal catalysis Catalysis plays a pivotal role in the development of environmentally friendly and efficient chemical processes towards the synthesis of high-value chemicals from abundant and renewable feedstocks. On the quest of more sustainable synthesis, our research group focuses on the discovery and development of organic reactions catalyzed by middle and late first-row metals (Mn, Fe, Co, Ni).

GDCh-Kolloquium: Professor Dr. Karl Gademann, Universität Zürich
Professor Dr. Karl Gademann, Universität Zürich Microbiome Metabolites: Syntheses and Surprises The microbiome is composed of different microorganisms such as bacteria that live on or in a complex host, such as e.g. humans or plants. Estimates suggest that bacterial cells outnumber their human host cells by as much as 10:1, leading directly to the question: Who is in control? Interactions, and ultimately control of the microbiome with their host might involve the trading and trafficking of chemicals. We will present recent studies from our group investigating small molecule chemicals that serve as signals for bacterial communication, cyclitols for chemical offense, and a recent total synthesis of peyssonnoside A which might be produced by the microbiome of red algae, complemented with other terpene syntheses.

GDCh-Kolloquium: Prof. Dr. Erwin Reisner, University of Cambridge
Prof. Dr. Erwin Reisner, University of Cambridge, UK Sunlight-Powered Circular Chemistry Solar panels are well established to produce electricity as photovoltaic cells and are already in advanced development to photo-catalyse overall water splitting to produce green hydrogen as artificial leaves or photocatalyst sheets. This presentation will introduce solar chemistry panels as an emerging technology to enable sunlight-powered circular carbon chemistry. Our progress in designing and constructing prototype solar devices for the direct conversion of carbon dioxide as well as the coupling to the valorisation of biomass and plastic waste streams into renewable fuels and higher-value chemicals will be presented.
