Metal nanostructures can concentrate light so strongly that they can trigger chemical reactions. The key players in this process are plasmons—collective oscillations of free electrons in the metal that confine energy to extremely ...
Using proteins from a common tobacco plant virus, McGill chemistry researchers have developed a simple, eco-friendly way to arrange gold nanoparticles into ultrathin sheets, strengthening the particles' optical properties. ...
A particle accelerator that produces intense X-rays could be squeezed into a device that fits on a table, my colleagues and I have found in a new research project.
A research team at the City University of New York and the University of Texas at Austin has discovered a way to make previously hidden states of light, known as dark excitons, shine brightly, and control their emission at ...
In a study published in Analytical Chemistry, a research team led by Wang Junfeng from the Hefei Institutes of Physical Science of the Chinese Academy of Sciences has developed a novel immobilization method for surface plasmon ...
Nonlinear optical dynamics—intensity-dependent response of light upon interaction with materials under high-intensity light sources—are of huge significance in modern photonics, finding applications in fields ranging from ...
Using ultra-fast laser beams, a team from the Irradiated Solids Laboratory has designed an experiment that allows both the creation of nanometric cavities in metal films and their study using several advanced microscopy techniques. ...
In the right combinations and conditions, two-dimensional materials can host intriguing and potentially valuable quantum phases, like superconductivity and unique forms of magnetism. Why they occur, and how they can be controlled, ...
Researchers at Michigan State University have discovered how to "draw" on demand the crystals used in many crucial technologies, from solar panels and LED lighting to medical imaging.
Scientists are exploring many ways to use light rather than heat to drive chemical reactions more efficiently, which could significantly reduce waste, energy consumption, and reliance on nonrenewable resources.
