Three EE seniors elected to Phi Beta Kappa honor society
Three graduating Electrical Engineering seniors - Madison White, Kristina Bohl and Arun Prasad - were recently inducted into Stanford's Phi Beta Kappa honors society.
Phi Beta Kappa is a nationwide society honoring students for the excellence and breadth of their undergraduate scholarly accomplishments. Membership in the Stanford Chapter (Beta of California) is open to undergraduates of all majors. To be elected to Phi Beta Kappa at Stanford, a student must achieve academic distinction in the major as well as in courses across a broad range of fields.

New Stanford Nanoscavengers Could Usher in Next Generation Water Purification
Among its many talents, silver is an antibiotic. Titanium dioxide is known to glom on to certain heavy metals and pollutants. Other materials do the same for salt. In recent years, environmental engineers have sought to disinfect, depollute, and desalinate contaminated water using nanoscale particles of these active materials. Engineers call them nanoscavengers. The hitch from a technical standpoint is that it is nearly impossible to reclaim the nanoscavengers once in the water.
In a paper published online May 14 in the journal Nature Communications, an interdisciplinary team of engineers at Stanford University announces it has developed a new type of nanoscavenger with a synthetic core that is ultraresponsive to magnetism, allowing the easy and efficient recovery of virtually every one of the nanoscale purifiers.
“In contaminated water, nanoscavengers float around, randomly bumping into and killing bacteria or attaching themselves to the molecular pollutants they are after,” said Shan Wang, the study’s senior author and a professor of material science and engineering and jointly of electrical engineering. “When the contaminants are either stuck to the nanoscavenger or dead, the magnet is turned on and the particles vanish.”

Stanford physicists develop revolutionary low-power polariton laser
Lasers are an unseen backbone of modern society. They're integral to technologies ranging from high-speed Internet services to Blu-ray players.
The physics powering lasers, however, has remained relatively unchanged through 50 years of use. Now, an international research team led by Stanford's Yoshihisa Yamamoto, a professor of electrical engineering and of applied physics, has demonstrated a revolutionary electrically driven polariton laser that could significantly improve the efficiency of lasers.
The system makes use of the unique physical properties of bosons, subatomic particles that scientists have attempted to incorporate into lasers for decades.

Numerical Technologies Founders Prize, Top EE Qualifying Exam Performer
The Numerical Technologies Founders awards were established by Dr. Yao-Ting Wang (Ph.D., 1997) and his advisor Professor Thomas Kailath, co-founders of Numerical Technologies, Inc., and their spouses. The company was created to commercialize the resolution enhancement techniques for optical lithography developed in Dr. Wang’s dissertation as part of a DARPA-sponsored project (1990-2000) on the applications of Control and Signal Processing to Semiconductor Manufacturing. The theme of the project was to demonstrate the power of the Mathematical Engineering approach: going from an ill-defined physical problem to an idealized mathematical model, its often-approximate solution, and then compromises for practical implementation and transition to industry. The first applications were to Rapid Thermal Processing and then to Optical Lithography where, when the project began, the industry was facing a so-called 100nm barrier. Numerical Technologies, in collaboration with Motorola, were the first to show that the barrier could be broken. This spurred further development of a host of resolution enhancement techniques the barrier has been lowered to 32nm. The company was founded in 1995, went public in 2000, and was acquired by Synopsis, Inc. in 2003. A different measure of the importance of the Mathematical Engineering approach is that the work on Rapid Thermal Processing won outstanding paper prizes in 1994 and 2003 from the IEEE Transactions on Semiconductor Manufacturing.
