Cost-Effective Diffraction Spectrometer Tunes Lasers with High Accuracy

Every photon in a laser beam marches in lockstep, at an identical wavelength that depends on what the laser is used for – for example, infrared lasers that drive the optic fiber internet.

Uncertainties in Blackbody Radiation Shift May Impose Limits on Accuracy of Atomic Clocks

No man is an island, entire of itself, said poet John Donne. And no atom neither. Even in the middle of intergalactic space, atoms feel the electromagnetic field---also known as the cosmic microwave background---left over by the Big Bang.

Novel Diffraction Spectrometer May Help Elucidate Quantum Mechanical Structure of Matter

Every photon in a laser beam marches in lockstep, at an identical wavelength that depends on what the laser is used for – for example, infrared lasers that drive the optic fiber internet. For many applications, lasers need to be precisely tuned to those wavelengths, and the wavelength-measuring instruments can be more expensive than the lasers themselves.

Researchers Employ Quantum Dots to Explore Effect of High Traffic on Active Transport via Microtubules

Inside many growing cells, an active transport system runs on nano-sized microtubule tracks that resemble a highway, complete with motors carrying cargo quickly from a central supply depot to growing tips or wherever materials are needed. In spite of the cell's busy, high-traffic environment, researchers know the system somehow works efficiently, without accidents or traffic jams.

Virtual Tool Precisely Twists and Turns Living Cells, DNA and Microscopic Motors

Harnessing laser light's ability to gently push and pull microscopic particles, researchers have created the fiber-optic equivalent of the world's smallest wrench. This virtual tool can precisely twist and turn the tiniest of particles, from living cells and DNA to microscopic motors and dynamos used in biological and physical research.

Charged Quasi-Particles Can be Manipulated for Applications in Optoelectronics and Valleytronics

When the dry lubricant, molybdenum disulfide, is stripped down to a single layer of atoms, a tightly bound quasi-particle comprised of two electrons and a hole forms with unique spin and valley properties, researchers from Case Western Reserve University and colleagues discovered.

Researchers Measure Temporal Profile of Free-Electron Laser X-ray Pulses with Femtosecond Precision

With their ultra short X-ray flashes, free-electron lasers offer the opportunity to film atoms in motion in complicated molecules and in the course of chemical reactions. However, for monitoring this motion, the arrival time and the temporal profile of the pulses which periodically illuminate the system, must be precisely known.
