Entrepreneurship and Law

Entrepreneurship and Law -Subtitle: Things Startups Must Do, Should Do, and Should Not Do This lecture explores what startups must do, should do, and should not do from a legal perspective during the preparation for entrepreneurship,  incorporation, and the process of running a corporation. More specifically, it covers topics such as determining the legal form of a business entity, matters to be determined when establishing a corporation, an overview of the structure of a Corporation, partnership agreements, legal obligations enforced by legislation depending on the industry such as e-commerce...

Paths to realistic lignin valorization to biofuels and bioproducts

Abstract     Lignin is an abundant, heterogeneous aromatic polymer found in plant cell walls where it serves functions in water and nutrient transport, defense against pathogens, and structural integrity. Lignin is the most abundant source of renewable aromatic compounds on Earth, but the heterogeneity, reactivity, and recalcitrance of lignin together pose a substantial challenge to convert it to renewable fuels, chemicals, and materials. In this talk, I will focus on two parallel pathways that we have been investigating for lignin valorization, the first to produce biofuels and the second to produce biochemicals.   The first pathway involves the use of lignin-first biorefining coupled to hydrodeoxygenation catalysis to manufacture sustainable aviation fuel blendstocks. Lignin-first biorefining methods are able to selectively remove lignin from the intact plant cell wall, and stabilize the reaction products to a lignin oil rich in aromatic monomers and small oligomers. We have conducted techno-economic analysis and life cycle assessment of a popular lignin-first biorefining method, reductive catalytic fractionation, which has informed research directions in solvent use reduction, reaction engineering, and separations. More recently, we have shown that lignin oil from reductive catalytic fractionation can undergo solvent-free, continuous hydrodeoxygenation, resulting in high yields of lignin-derived aromatic blendstocks for sustainable aviation fuel.   The second pathway we are investigating involves the conversion of lignin to a single, tunable bioproduct. Herein, we are focused on the selective aerobic oxidation of lignin to cleave C–C bonds and to produce heterogeneous mixtures of aromatic carboxylic acids, which can be biologically converted into a single bioproduct, in a process we termed “biological funneling”. This work involves integration of chemical catalysis, separations, metabolic engineering, and bioprocess development. In this part of the talk, I will highlight the work we have done to cleave C–C bonds using aerobic oxidation catalysis and to engineer Pseudomonas putida KT2440 for optimal biological funneling of mixtures of aromatic compounds to single, atom-efficient bioproducts, such as 3-oxoadipic acid and cis,cis-muconic acid....

Technology, into the Market

Engineering is not simply a study to solve our curiosity, but it is meaningful only when someone actually uses its outcome. In this presentation, we will take a look at the process that the technology developed in academia actually goes through to enter the market...
