A team working at the SACLA X-ray Free-Electron Laser (XFEL) in Japan has succeeded in generating ultra-bright, two-color X-ray laser pulses, for the first time in the hard X-ray region. These light pulses with different wavelengths, whose time separation can be adjusted with attosecond accuracy, are powerful tools to investigate the structure of matter and the dynamics of ultrafast physical processes and chemical reactions.
If the promise of nanotechnology is to be fulfilled, then research programs must leapfrog to new nanomanufacturing processes. That's the conclusion of a review of the current state of nanoscience and nanotechnology.
Accurate and reliable measurement of volatile organic compounds (VOCs) is an important need in many application areas in industry, air pollution and atmosphere, health and well-being, defense and security as well as in many other fields. In a new thesis, cantilever-enhanced photoacoustic spectroscopy has been applied for the measurement of VOCs.
In light of debates that make nanotechnologies responsible for a further widening of the aforementioned divide, this new report analyses this Nano-Gap, or Nano-Divide, by examining the pros and cons of nanotechnologies and their impact global development and the on-going fight against poverty.
Stanford researchers have received Bio-X funding to develop a tiny moving probe to study the mechanical properties of sensory cells in the ear. Their research could lead to new treatments for hearing loss, and the probe may advance other scientists' research as well.
A collaboration of physicists and engineers has found a new way to control electron spins not with a magnetic field but with a mechanical oscillator - a demonstration of electron spin resonance that's 'shaken, not stirred'.
The National Institute of Standards and Technology (NIST) announced today that it has selected a consortium led by Northwestern University to establish a new NIST-sponsored center of excellence for advanced materials research. The new Center for Hierarchical Materials Design (CHiMaD) will be funded in part by a $25 million award from NIST over five years.
A research team at Berkeley Lab has discovered a way to introduce a recoverable strain into bismuth ferrite of up to 14-percent on the nanoscale, larger than any shape-memory effect observed in a metal. This discovery opens the door to applications in a wide range of fields, including medical, energy and electronics.
This is the first time to introduce a biotemplated inorganic piezoelectric material to a self-powered energy harvesting system, which can be realized through eco-friendly and efficient material syntheses.
Iowa State's Balaji Narasimhan thinks nanovaccines can revolutionize the prevention and treatment of diseases. And so he's using an Iowa State presidential research grant to assemble a 'dream team' to research and develop nanovaccines.
