Injectable Microbubbles in Hydrology and Healthcare

Fanny Littmarck February 1, 2013

Microbubbles filled with oxygen can be injected into contaminated lakes to restore the water quality. Typically, water is purified via water-treatment plants, but this microbubble technique is both inexpensive and more environmentally-friendly in comparison. As seen in a COMSOL News 2011 article, oxygen microbubbles are a researcher’s way of copying nature’s own self-restoration mechanism for cleaning contaminated lakes.

If I asked you to envision a wind turbine, odds are you’d picture a wind farm in some remote location. With good reason; that’s commonly where they are found. If you’re a student or faculty of Case Western Reserve University, on the other hand, you might think of the wind turbine you have on campus. Does it make sense to set up wind turbines in urban settings? These two researchers suggest that it does.

December of 1903 marked the commencement of the Age of Powered Flight, and the Wright brothers went down in history. This was a time before personal computers and simulation software existed. Determining the optimal design of their airplane had to be done using physical prototypes and real-life experiments. What had the design looked like if the Wright brothers had been able to use computers and modeling software? Three researchers from Pennsylvania State University sought to find out how the design […]

Much has been written lately about increasing the energy efficiency of cars. Batteries and fuel cells are very hot topics, and not so long ago I blogged about the University of Michigan’s use of solar cells to fully power a car. Yet, even on the smallest of scales, such as the sensors in your car, improvements are being made. Utilizing a MEMS (Micro Electromechanical System) piezoelectric energy harvester, Alexander Frej and Ingo Kuehne at Siemens Corporate Technology in Munich are […]

Remember those retro desk ornaments of the 1960’s, those lamps filled with colorful wax that began to move when the lamp was lit? I’m talking about lava lamps, or as I like to call them, “Rayleigh–Taylor instability machines”. They may not be popular among today’s youth, but I still own one and I thought it would be interesting to look beyond the dyed blobs of wax and observe the physics involved in lava lamps.

According to a study done by Brunel University in the United Kingdom, the food sector is among the top five energy-consuming industries. The transportation of food, including keeping it refrigerated, is one of the larger contributing factors to this energy-consumption and subsequent greenhouse gas emissions.
