Graduate student Suhail Yusuf Khan recently gave a lecture and demonstration at the Department of Ethnomusicology at the University of California, Los Angeles. Khan’s lecture focused on the sarangi and its use in popular music contexts.

Khan was invited to UCLA to lecture to a global pop music class.

“The idea was to show students some of my experimental and pop music,” Khan said.

During his demonstration, Khan spoke about the the sarangi’s role in Hindustani music and the relationship to the voice. He also showed different playing techniques, and shared his own musical story, including the challenges he faces as a classically trained musician navigating the global popular music industry.

Khan, from New Delhi, India, is working towards his master’s degree in music. He also is a composer, singer and songwriter. After graduating from Wesleyan, he is considering applying to PhD programs in ethnomusicology or will continue to perform around the world.

A PhD candidate in chemistry will spend two years in Germany working on microwave spectroscopy research.

As a recipient of the prestigious Alexander von Humboldt Research Fellowship, Dan Obenchain will continue his studies at the University of Hanover. He will start his fellowship in August 2016 after taking two months of intensive German language classes.

On March 4, Dan Obenchain met with Jens Grabow, a professor from the Institute of Physical Chemistry and Electrochemistry at the University of Hanover. Grabow was visiting Wesleyan to speak at the Department of Chemistry's Colloquium. Obenchain will work with Grawbow for the next two years in Germany.

Grabow was visiting Wesleyan to speak at the Department of Chemistry’s Colloquium. Obenchain will work with Grabow for the next two years in Germany.

The Alexander von Humboldt Foundation brings young and senior scientists from around the world to Germany to conduct research in many different fields of science.

“Thankfully, working at Wesleyan has given me many great opportunities to publish my work. The faculty of both the chemistry and physics departments have been very supportive throughout my time at Wesleyan,” Obenchain said.

At the University of Hanover, Obenchain will work alongside Jens-Uwe Grabow, a professor from the Institute of Physical Chemistry and Electrochemistry. Both Obenchain and Grabow are microwave spectroscopists who study the properties of molecules by observing how they rotate. In 2015, Obenchain wrote a research proposal that looks at the interaction of two metals found in bimetallic nano-particles. Nano-particle research is a growing field of materials science, and is helping to make advances in many fields, including fuel cell efficiency and in polymer synthesis.

“Thinking about what we do is similar to thinking about a figure skater spinning in place. The skater will go faster if they bring their arms into their body, and slower if they extend them out. We use the same ideas when molecules rotate to determine their shapes and the type of chemistry they can do,” Obenchain explained.

In addition to having similar research interests, Obenchain and Grabow also design and maintain their own research instruments. Wesleyan’s Machine Shop constructed Obenchain’s microwave spectrometer, which mimics Grabow’s design in Germany.

After graduating from Wesleyan with a PhD in chemistry this May, Dan Obenchain will conduct research in Germany

After graduating from Wesleyan with a PhD in chemistry this May, Dan Obenchain will conduct research in Germany.

“Jens is not only a great scientist, he’s the best at designing and building microwave spectrometers,” Obenchain said. “I am more of a MacGyver when it comes to the instruments, while Jens is more of a Michelangelo. Hopefully, I can gain some of his expertise as one day I’d like to start my own academic research lab.”

Obenchain, who is completing his fifth year at Wesleyan, plans to defend his thesis at the end of the month and graduate in May. In addition to his research in Hanover, Obenchain looks forward to exploring Germany “and experiencing its culture, and hopefully seeing a Bundesliga soccer match at some point.”

After completing his fellowship, Obenchain will join more than 27,000 Humboldt Foundation alumni worldwide – the Humboldtians.

Professor Francis Starr, graduate student Hamad Emamy and collaborators from the Brookhaven National Lab have co-authored a paper titled “Diamond Family of Nanoparticle Superlattices” published in the prestigious journal Science on Feb. 5. Starr is professor of physics and director of the College of Integrative Sciences.

Their work proposed a solution to a decades-long challenge to self-assemble a diamond-structured lattice at will from nanoscale particles.

“Such a diamond-lattice structure has long been sought after due to its potential applications as a light controlling device, including optical transistors, color-changing materials, and optical — as opposed to electronic — computing,” Starr said.

To solve this challenge, the team utilized the specific binding properties of DNA as a tool for materials science. Specifically, they created nanoscale “atoms” that consist of 15 nanometer gold nanoparticles coated with many single-stranded DNA. The single-stranded DNA act like binding arms to connect nanoparticle/DNA “atoms” by forming double-stranded DNA links, and analogue of traditional chemical bonds between atoms. By appropriate selection of the sequence and orientation of these DNA links, the nanoparticles will spontaneously arrange themselves into the desired structure.

“This self-assembly approach not only allows for highly specific order, but also offers the potential for tremendous savings in the cost of materials production, as compared to traditional methods used in the semi-conductor industry,” Starr explained.

Emamy, a graduate student in Starr’s lab, carried out numerical simulations that helped to develop the approach and explain how to stabilize the structure. Collaborators at Brookhaven experimentally synthesized and verified the structure and properties. The effort, Starr said, represented an ideal collaboration between experiments, theory and computation.
