The lecture will explore the role of technology in promoting environmental sustainability. It focuses on the development and implementation of innovative technologies that can help address environmental challenges and contribute to a more sustainable future.We are developing green technologies to benefit sustainable environment, which will enable people and the environment to prosper together. The Center for Filtration Research (CFR) at the University of Minnesota, collaborating with 20 leading international filtration manufacturers and end users, was established to develop green technologies to mitigate PM2.5, VOCs, ozone and other environmental pollutants. CFR investigators perform fundamental and applied research on air, gas and liquid filtration. The current research projects include indoor air cleaning and Covid prevention, bioaerosols sensor development and evaluation, nanofiber production and modeling, nanotechnology and instrumentation developments, among others. Large-scale air cleaning towers are established in Xi’an and Yancheng in China, and two additional towers in Delhi, India. They are developed to mitigate PM2.5 pollutants in urban air. The second-generation tower in Yancheng is developed to reduce not only the PM2.5 but also CO2 in the atmosphere. The construction of a set of large-scale air cleaning towers to capture 16 million tons of CO2 annually is proposed. All these research and development activities are helping to improve sustainable environment.

Water shortage is one of the biggest challenges that humanity faces. Novel technologies to tackle the challenge of water scarcity are urgently needed. However, all the existing studies are based on bare fibers with diameter in the order of mm. This talk introduces a novel fog collection technology using microfibers fabricated by near-field electrospinning. The collection efficiency reaches a record high level. Systematic investigation reveals that the waterdrops are “visible” to fog droplets in the incoming air flow because of the relatively small size of the microfibers. Thus, the large waterdrops deflect the fog-carrying airflow to the satellite small waterdrops, which effectively intercept the fog droplets.

Welcome to Control Systems Lectures! This collection of videos is intended to supplement a first year controls class, not replace it. My goal is to take specific concepts in controls and expand on them in order to provide an intuitive understanding which will ultimately make you a better controls engineer.

This course covers the fundamentals of advanced fluid mechanics: including its connections to continuum mechanics more broadly, hydrostatics, buoyancy and rigid body accelerations, inviscid flow, and the application of Bernoulli’s theorems, as well as applications of control volume analysis for more complex fluid flow problems of engineering interest. This course features lecture and demo videos, lecture concept checks, practice problems, and extensive problem sets.
This course is the first of a three-course sequence in incompressible fluid mechanics: Advanced Fluid Mechanics: Fundamentals, Advanced Fluid Mechanics: The Navier-Stokes Equations for Viscous Flows, and Advanced Fluid Mechanics: Potential Flows, Lift, Circulation & Boundary Layers. The series is based on material in MIT’s class 2.25 Advanced Fluid Mechanics, one of the most popular first-year graduate classes in MIT’s Mechanical Engineering Department. This series is designed to help people gain the ability to apply the governing equations, the principles of dimensional analysis and scaling theory to develop physically-based, approximate models of complex fluid physics phenomena. People who complete these three consecutive courses will be able to apply their knowledge to analyze and break down complex problems they may encounter in industrial and academic research settings.
`The material is of relevance to engineers and scientists across a wide range of mechanical chemical and process industries who must understand, analyze and optimize flow processes and fluids handling problems. Applications are drawn from hydraulics, aero & hydrodynamics as well as the chemical process industries.

"A Brief Introduction to Engineering Computation with MATLAB is specifically designed for students with no programming experience. However, students are expected to be proficient in First Year Mathematics and Sciences and access to good reference books are highly recommended. Students are assumed to have a working knowledge of the Mac OS X or Microsoft Windows operating systems. The strategic goal of the course and book is to provide learners with an appreciation for the role computation plays in solving engineering problems. MATLAB specific skills that students are expected to be proficient at are: write scripts to solve engineering problems including interpolation, numerical integration and regression analysis, plot graphs to visualize, analyze and present numerical data, and publish reports."--BC Campus website.
