Engineering superhydrophobic and superoleophobic surfaces

Tuteja A., Choi W., Mabry J.M., McKinley G.H., Cohen R.E., Massachusetts Institute of Technology, US

The combination of surface chemistry and roughness on multiple scales imbues enhanced repellency to the lotus leaf surface when in contact with a high surface tension liquid such as water. This understanding has led to [...]

Sustainable Energy Opportunities with the Geothermal Continuum

Thorsteinsson H., Augustine C., Anderson B.J., Moore M.C., von Rohr P.R., Tester J.W., Massachusetts Institute of Technology, US

The publication of “The Future of Geothermal Energy” in 2006, which resulted from a comprehensive assessment of US geothermal potential, brought renewed interest in Engineered Geothermal Systems (EGS) worldwide. The magnitude and accessibility of the [...]

Using Microfluidics for Metabolic Monitoring of Single Embryo Cultures

Thorsen T., Urbanski J.-P., Johnson M.T., Craig D.D., Potter D.L., Gardner D.K., Massachusetts Institute of Technology, US

In recent years, microfluidics has demonstrated novel methods of culturing and studying cells. Within well-defined volumes comparable to the sample of interest, media, nutrients or toxins may be precisely targeted to individual cells via diffusion [...]

Well-ordered Semiconductor Wire-Arrays Driven by in-Fibre Capillary Layer Breakup

Deng D.S., Orf N., Abouraddy A.F., Fink Y., Massachusetts Institute of Technology, US

One-dimensional structures with nanometre scale have been demonstrated with substantial progresses for device applications in electronics, photonics, photovoltaics and biology. The fabrication for the well-ordered extended semiconductor wires is highly desirable for the alignment and [...]

Enhancement of in vitro Capillary Tube Formation by Substrate Nanotopography

Bettinger C.J., Zhang Z., Gerecht S., Borenstein J.T., Langer R., Massachusetts Institute of Technology, US

Controlling the morphology and function of cells using substrate nanotopography is a phenomenon that can be utilized in a variety of fields including tissue engineering and regenerative medicine. In this work, we explored the possibility [...]

Biomolecular activity switch: an application of metallic nanoparticle plasmon resonance

Alper J., Wijaya A., Crespo M., DeFlores L., Tokmakoff A., Hamad-Schifferli K., Massachusetts Institute of Technology, US

Specific external control of biomolecular activity is a critical step in harnessing the power of nature’s molecular machinery. We propose and demonstrate one control method, a biomolecular activity switch. Since proteins are the primary macromolecule [...]

Preparation and Characterization of Various Nanofluids

Williams W.C., Bang I.C., Forrest E., Hu L.W., Buongiorno J., Massachusetts Institute of Technology, US

As part of an effort to evaluate water-based nanofluids for nuclear applications, preparation and characterization has been performed for nanofluids being considered for MIT’s nanofluid heat transfer experiments. Three methods of generating these nanofluids are [...]

Enhancement of Oxygen Transfer in Fermentation by Use of Functionalized Magnetic Nanoparticles

Olle B., Bromberg L., Hatton T.A., Wang D.I.C., Massachusetts Institute of Technology, US

Maintaining an adequate oxygen supply to aerobic cell cultures has been a long-standing problem in fermentation technology. Insufficient oxygen transfer rates limit cell growth and ultimately process productivity. Our approach to reducing the oxygen transport [...]
