Science in Action Winner for 2013: Elif Bilgin

Science in Action Winner for 2013: Elif Bilgin

“Genius,” Thomas Edison famously said, “is 1 percent inspiration and 99 percent perspiration.” He would have found a kindred spirit in Elif Bilgin, 16, of Istanbul, Turkey, winner of the 2013 $50,000 Science in Action award, part of the third annual Google Science Fair. The award honors a project that can make a practical difference by addressing an environmental, health or resources challenge; it should be innovative, easy to put into action and reproducible in other communities.

Bilgin spent two years toiling away on her project to develop a bioplastic from discarded banana peels, enduring 10 failed trials of plastics that weren’t strong enough or that decayed rapidly. She was undaunted. As she put it in her project description: “Even Thomas Edison said, ‘I have not failed. I have just found 10,000 ways that won’t work.’” Finally, in her last two trials, she made plastics with the features she sought, and it did not decay. We admire her persistence, which will be help her to take advantage of another aspect of her Science in Action prize—a year’s worth of mentoring to help further her work. I like to think, too, that Edison, who used to stop by the Scientific American offices in New York City to demonstrate his latest inventions, would have approved.

The ingredients to make Bilgin’s plastic are relatively benign. As she wrote in her entry materials, “it is possible to say that one could do it at home.” In her research, she learned that starch and cellulose are used elsewhere in the bioplastic industry (such as from the skin of mangoes) and made the leap that banana peels might be suitable feedstock sources as well. She hopes that the use of the bioplastic could replace some of the petroleum-based plastics .........

Worldwide, 16 projects, seven male researchers and nine female or team (one group of 2 women, another of three).

Among my favorites were:

A Novel Implementation of Image Processing and Machine Learning for Early Diagnosis of Melanoma

A multi-step system was created for early diagnosis of melanoma cancers. Image processing algorithms (edge detection and image segmentation) were used to extract the standard ABCD (Asymmetry, Border, Color, and Diameter) features of a skin mole. The extracted ABCD features were analyzed statistically to understand the impact of each characteristic. The features were then further tested in a machine learning algorithm known as Artificial Neural Networks for a comprehensive diagnosis. These combined steps provided about 80% accuracy and can successfully function as preliminary cancer diagnosis.


Solar Light Assisted nanoZnO Photo Catalytic Mineralization- The Green Technique for the Degradation of Detergents

Wastewater containing detergent from industrial and domestic source creates huge pollution in our cities. To treat this waste containing detergents is quite difficult since detergents are quite rugged and resistant to degrade. I wish to find out a potential Green method to treat this polluted waste.

Nano ZnO assisted photo catalytic degradation using solar light is emerging as new green option for the treatment of contaminated water.

The advantages of my method are summarized as follows: fast reaction, short treatment time, less costs, less exposure for workers, complete reduction pathway to non-toxic end products is possible and less equipment.

Preliminary studies have shown that the proposed method is quite effective in remediating the waste water. After lab synthesis of nanoZnO characterization has been done using various methods such as XRD (X-Ray Diffraction).

I propose to design a batch reaction system demonstrating that the representative detergent Cetyl Pyridinium Chloride can be effectively degraded by using nanoZnO. Mineralization of the detergents would be confirmed using UV spectrum and COD determination.


Rapid Quantum Dot Solar Cell Optimization: Integrating Quantum Mechanical Modeling and Novel Solar Absorption Algorithm

Quantum dot (QD) solar cells are theoretically twice as efficient as conventional solar cells, but state-of-the-art research QD cell efficiency is very low. Significant, rapid optimization is urgently needed.

A novel research method is proposed and demonstrated using PbSe QDs, combining quantum mechanical absorption coefficients and solar irradiance. Cloud computing and Python programming is used to implement the novel algorithm for each QD configuration. The model was validated against published experiments.

Results indicate that QD performance highly depends on shape and size, and optimal peak QD conditions are identified. This method will enable rapid optimization of QDs for solar applications.



Good work by Google inspiring, supporting, and rewarding the next generations of scientists. Learning what these young people are doing, and knowing what they are capable of doing in the future, restores a bit of hope for this planet and its human population.

Thanks for the post, Coyotl.
