Modern Tek News on KZSU, Stanford 90.1 FM
News about nanotechnology, devices and sensors!
Professor Hilmi Volkan Demir

​Professor Demir teaches engineering at Bilkent University in Turkey.  He is Director of their Devices and Sensors Research Lab.  Professor Demir received his Ph.D. in EE from Stanford University in 2000 and now has 30 patents on sensors, electronic devices, LEDs and nano-materials. 

Professor Demir is also an entrepreneur; he started a nanotechnology company, Innovcoat, which is now a joint-venture with France.  Innovcoat makes nano-materials that protect different kinds of surfaces against bacteria, mildew, scratches, fire, and other customer specified applications.

During KZSU's interview, Professor Demir discussed why nano crystal optoelectronics is making LEDs more efficient and how much energy we would save if we use LEDs.  19% of the world's energy consumption goes to lighting; Professor Demir said that LEDs can reduce this by about 50%.  We also discussed how lighting designers are now using LEDs in hospitals to improve the healing rate and how schools are starting to use LEDs to improve students' learning capabilities.  We also discussed the new organicLEDs (OLED) that are used in cell phones and other new electronic devices such as flexible displays and glasses, like google glass.  During the interview Professor Demir also discussed his group's patents on wireless medical sensors that are used in medical applications.

Professor Demir's interview was broadcast on KZSU in August, 2013 and is available from this link.
George Washington University' Licht Lab Shows How Climate Change Can Be Solved 
by Changing CO2 to Carbon Nanofibers:

KZSU interviewed Professor Stuart Licht about his Licht Research Lab's successful and inexpensive STEP Process that converts CO2 from the air into Carbon Nanofibers, which are lighter and stronger than steel.  Making 1 ton of Carbon Nanofibers would remove 4 tons of CO2 from the atmosphere.   

The STEP (Solar Thermal Electrochemistry Photo) Process is also used to extract Magnesium metal from seawater,  while making bleach and drinking water as byproducts.   Professor Licht also mentioned that he has used the STEP Process to make cement without emitting CO2 into the atmosphere.   In this interview, Professor Licht discussed home much Carbon Nanofibers we would need to use in buildings and in making batteries, so that we can begin to see a big reduction in the CO2 levels in the atmosphere.

Professor Licht's interview is available from this link.

We also interviewed famed architect Frank Gehry and we found out that he used carbon nanofibers to make his new sail boat Foggy2 and that his first sailboat was also made of carbon nanofibers because it is lighter than other materials used to make boats.

Interview with Dr. Elena Polyakova, Co-Founder Graphene 3D Lab

In 2016, the graphene market is about $110 Million; Dr. Elena Polyakova expects the graphene market to become a multi-million dollar market over the next 10 years.  In the interview Dr. Polyakova discussed how the company was started when no graphene products were commercially available and how she and her husband, Dr. Daniel Stolyarov were among the first to make graphene filaments commercially available for 3D printed products. Today, Graphene 3D Lab has many customers including NASA, HP, Apple, Ford Motor Company, MIT, Yale and Stanford University. Graphene materials are now used in sensors, as shock absorbers in the construction industry and many other fields.

Dr. Polyakova said that Graphene 3D Lab could work with science teachers to develop projects that interest Middle and High School students in using graphene filaments in 3D printing. We also discussed how 3D printing with graphene filaments will change manufacturing, including car and drone manufacturing. For more information about graphene filaments for 3D printing, please contact their subsidiary Black Magic 3D. Graphene 3D Lab distributes some of its products through its wholly owned subsidiary, Graphene Supermarket.

​Dr. Polyakova had advice for students who are interested in studying nano materials-materials and for people who would like to start their own companies.

KZSU broadcast this interview in December, 2016. The interview is available from this link.
