Conventional spontaneous Raman spectroscopy of interfacial molecules typically requires plasmonic or electronic enhancement, limiting accessible systems. A nonlinear coherent Raman method now enables direct, high sensitivity detection without such requirements.

What people see on screen can shape what they do off it. When actors such as James Dean and Marlon Brando lit cigarettes in 1950s rebel films, smoking came to signify cool, defiance and desire for an entire generation.
Researchers from the Department of Physical Chemistry at the Fritz Haber Institute and Freie Universität Berlin have revealed the arrangement of water molecules at the interface between liquid water and air. Their findings help to better understand interfacial chemistry, which is largely determined by the specific arrangement of the water molecules. Published in Science Advances, the study shows that one parameter in particular—one that has been neglected until now—is of fundamental importance:
As digital tools become more common in teamwork, many organizations hope they can help teams collaborate more effectively. But a new study suggests that some uses of tools—such as providing real-time feedback on collaboration via specific metrics—do not necessarily improve how teams work and in some cases may even make performance worse.
While the world is a big place, humans are making greater and greater demands on the same areas of land. "This means that, unless we use the same land to serve multiple needs and coordinate this effort through planning, it is unlikely that we will have enough land for conservation, food and energy," said Grace Wu, a professor in UC Santa Barbara's Environmental Studies Program.
