Vapour–liquid–solid route and its variants are routinely used for scalable synthesis of semiconducting nanowires, yet the fundamental growth processes remain unknown. Here we employ atomic-scale computations based on model potentials to study the stability and growth of gold-catalysed silicon nanowires. Equilibrium studies uncover segregation at the solid-like surface of the catalyst particle, a liquid AuSi droplet, and a silicon-rich droplet–nanowire interface […]

U.S. Sen. Elizabeth Warren and U.S. Rep. John Tierney (D-Salem) yesterday touted their bill to prevent the federal student loan interest rate from doubling next month and let students, for one year, pay the lower rate major banks do — though experts say the proposal would have no effect on the economy or the soaring […]

About 6 years ago, I was appointed the Massachusetts Commissioner of Public Health just as the state’s groundbreaking health care legislation was on the verge of being implemented. Certain things we clearly anticipated. The Massachusetts Medicaid Program (known as Mass Health) would surely expand its eligibility criteria so that a few hundred thousand more residents could enroll. The country’s first insurance exchange—the Connector—would be […]

Professors at Northeastern University in Boston examined 42 neighborhoods in 12 U.S. cities in 2010 and found that housing costs near rail stops increased after light-rail service started in many markets. “A new transit station can set in motion a cycle of unintended consequences in which core transit users…are priced out in favor of higher-income, […]

But local Pittsburgh politics aside, large non-profit health systems are getting new attention from city and state tax officials across the country facing budget crises. “The fact is hospitals are coming under more scrutiny,” says Gary Young, director of Northeastern University’s Center for Health Policy and Healthcare Research. “The city’s willingness to take on a […]

In fact, many of the most infamous violent attacks have been acts committed by individuals, not by groups. Think the Oklahoma City bombing, the first World Trade Center attack, the underwear bomber who was thwarted, and the countless campus and school shootings that have claimed the lives of many. All of these acts were plotted, […]

There’s been a lot of public and private handwringing within the legal establishment in recent years. There’s anxiety — and outrage — over the spiraling cost of legal education and the diminishing opportunities and salaries for recent law school grads. And there’s no small dissatisfaction with the ability of those grads to actually practice the […]

James Alan Fox, a professor of criminology at Northeastern University in Boston and former consultant to the International Council of Cruise Lines, has testified before congress about cruise ship safety.
