Scientific Reports
POSTECH researchers develop a control algorithm for more accurate lab-on-a-chip devices
Prof. Wan Kyun Chung with Ph.D. student Young Jin Heo, M.S. student Junsu Kang, and postdoctoral researcher Min Jun Kim in the Robotics Laboratory at POSTECH, Korea, have developed a novel control algorithm to resolve critical problems induced from a Proportional-Integral-Derivative (PID) controller by automatizing the technical tuning process. The team expects that this algorithm has the potential for many applications of lab-on-a-chip devices. Their research was published in Scientific Reports.

World's smallest diode, developed by U. of Georgia and Ben-Gurion U.
Dr. Dubi and his student, Elinor Zerah-Harush, constructed a theoretical model of the DNA molecule inside the electric circuit to better understand the results of the experiment. 'The model allowed us to identify the source of the diode-like feature, which originates from breaking spatial symmetry inside the DNA molecule after coralyne is inserted.'

NYU Tandon researcher synthesizes hybrid molecule that delivers a blow to malignant cells
A new molecule developed at NYU Tandon School of Engineering shows promise for treating breast cancer. The protein/polymer-gold nanoparticle composite, besides being easy to synthesize, can load up with drugs, carry them to malignant cells, and unload them where they can do the most damage with the least amount of harm to the patient. It was developed by Jin Kim Montclare, an associate professor in Tandon's Department of Chemical and Biomolecular Engineering.

Ruthenium nanoframes open the doors to better catalysts
Researchers have created the first ruthenium nanoframes by manipulating the metal's crystal structure. The two-part process could open up a new group of catalysts made from materials with unique atomic arrangements. If they prove to be efficient catalysts, they could also improve hydrogen fuel production and carbon storage.

Food Structure
For the first time scientists can observe the nano structure of food in 3-D
Scientists from the University of Copenhagen, Denmark, and the Paul Scherrer Institute, Switzerland, have, for the first time, created a 3-D image of food on the nanometer scale. The method the scientists used is called Ptychographic X-ray computed tomography. It has promising prospects as a more detailed knowledge of the structure of complex food systems could potentially save the food industry large sums of money and reduce food waste that occurs because of faulty production.

To provide oncologists a way to detect a single molecule of an enzyme produced by circulating cancer cells, physicists and engineers at Case Western Reserve University have developed an optical sensor, based on nanostructured metamaterials, that's 1 million times more sensitive than the current best available. The device proved capable of identifying a single lightweight molecule in a highly dilute solution.

Computer simulation discloses new effect of cavitation
Researchers have discovered a so far unknown formation mechanism of cavitation bubbles by means of a model calculation. In the Science Advances journal, they describe how oil-repellent and oil-attracting surfaces influence a passing oil flow. Depending on the viscosity of the oil, a steam bubble forms in the transition area. This so-called cavitation may damage material of e.g. ship propellers or pumps. However, it may also have a positive effect.

Saving sunshine for a rainy day: New catalyst offers efficient storage of green energy
We can't control when the wind blows and when the sun shines, so finding efficient ways to store energy from alternative sources remains an urgent research problem. Now, a group led by Professor Ted Sargent at the University of Toronto's Faculty of Applied Science & Engineering may have a solution inspired by nature. The team has designed the most efficient catalyst for storing energy in chemical form, just like plants do during photosynthesis.
