Bernoulli's principle relates the pressure of a fluid to its elevation and its speed. Bernoulli's equation can be used to approximate these parameters in water, air or any fluid that has very low viscosity. Students learn about the relationships between the components of the Bernoulli equation through real-life engineering examples and practice problems.

Have you ever asked what “biobased” means or wondered about the key aspects in developing and commercializing biobased products? This course will answer those questions and more; highlighting the opportunities, hurdles, and driving forces of the bioeconomy.

Today’s industries face enormous global challenges when it comes to the fossil-based economy. Fossil resources are no longer a desirable feedstock for many products and governments’ climate goals put various limitations to its usage. Moreover, consumer perception has become an increasingly important factor. With biobased products as an alternative to the fossil-based economy, the bioeconomy can provide viable solutions to these challenges.

The course describes the different types of biomass, the methods of refinery and typical conversion technologies used for biobased products. You’ll also engage in a study of the practical and real-life examples emerging in the market: biopolymers, bioenergy, bioflavours, and biosurfactants.

The course has been developed by a team of experts from seven different institutions and universities in three different countries, all sharing their personal perspectives on the opportunities and challenges faced by the biobased industry. The three top-ranked institutions Delft University of Technology, RWTH Aachen University, and Wageningen University & Research offer additional, more advanced courses to continue your learning journey:

Industrial Biotechnology: a more advanced course that digs deeper into engineering aspects of bio-based products.
MicroMasters Chemistry and Technology for Sustainability: Help drive the transition from fossil sources to renewable energy ones and engineer a biobased future.
Sustainable Development: The Water-Energy-Food Nexus: Introduction to sustainable development and its relation to the Water-Energy-Food Nexus.

Students learn how to manipulate the behavior of water by using biochar—a soil amendment used to improve soil functions. As a fluid, water interacts with soil in a variety of ways. It may drain though a soil’s non-solid states, or its “pores”; lay above the soil; or move across cell membranes via osmosis. In this experiment, students solve the specific problem of standing water by researching, designing, and engineering solutions that enable water to drain faster. This activity is designed for students to explore how biochar helps soils to act as “sponges” in order to retain more water.

Paul Andersen explains how biogeochemical cycles move required nutrients through the abiotic and biotic spheres on our planet. Matter on the Earth is conserved so producers must receive required nutrients through the water cycle, carbon cycle, nitrogen cycle, phosphorus cycle, and sulfur cycle.

In this video Paul Andersen explains how the structure of a biomolecule fits the function of the biomolecule. For example and enzyme must interact correctly with a substrate to lower the activation energy, The covalent and non-covalent interactions are both important in shaping large molecules.

This lesson begins with a demonstration prompting students to consider how current generates a magnetic field and the direction of the field that is generated. Through formal lecture, students learn Biot-Savart's law in order to calculate, most simply, the magnetic field produced in the center of a circular current carrying loop. For applications, students find it is necessary to integrate the field produced over all small segments in an actual current carrying wire.
