The Center for X-Ray Optics new technique for creating high-resolution zone plates involves two separate patterns of alternating zones fabricated sequentially and overlaid on the same wafer.
With the new technique the zones were spaced approximately 15 nanometers apart (30 nanometers between the centers of each gold zone). Future improvements will be directed at narrower zones with no gaps and even closer spacing.
Zone Plate Lenses Capable of Better than 15-Nanometer Resolution
Progress in nanoscience and nanotechnology depends not only on examining the surfaces of things but on seeing deep inside biological organisms and material structures to identify what they’re made of — and what electronic, magnetic, optical, and chemical processes may be in play.
For measuring internal variations in shape, organization, magnetism, polarization, or chemical make-up over distances of a few nanometers (billionths of a meter), x-ray microscopy not only complements electron microscopy but also offers important advantages. The XM-1 x-ray microscope at the Advanced Light Source, located at the Department of Energy’s Lawrence Berkeley National Laboratory, uses bright beams of "soft" x-rays to produce images that not only reveal structures but can identify their chemical elements and measure their electromagnetic and other properties as well.

Researchers from the Institute for Quantum Computing (IQC) at the University of Waterloo led the development of a new extensible wiring technique capable of controlling superconducting quantum bits, representing a significant step towards to the realization of a scalable quantum computer.
"The quantum socket is a wiring method that uses three-dimensional wires based on spring-loaded pins to address individual qubits," said Jeremy Béjanin, a PhD...
In a paper in Scientific Reports, a research team at Worcester Polytechnic Institute describes a novel light-activated phenomenon that could become the basis for applications as diverse as microscopic robotic grippers and more efficient solar cells.
A research team at Worcester Polytechnic Institute (WPI) has developed a revolutionary, light-activated semiconductor nanocomposite material that can be used...
By forcefully embedding two silicon atoms in a diamond matrix, Sandia researchers have demonstrated for the first time on a single chip all the components needed to create a quantum bridge to link quantum computers together.
"People have already built small quantum computers," says Sandia researcher Ryan Camacho. "Maybe the first useful one won't be a single giant quantum computer...
COMPAMED has become the leading international marketplace for suppliers of medical manufacturing. The trade fair, which takes place every November and is co-located to MEDICA in Dusseldorf, has been steadily growing over the past years and shows that medical technology remains a rapidly growing market.
In 2016, the joint pavilion by the IVAM Microtechnology Network, the Product Market “High-tech for Medical Devices”, will be located in Hall 8a again and will...
