Chemical Composition of Lithium Iron Phosphate Nanocrystals Mapped Using Ptychography

A record-setting X-ray microscopy experiment may have ushered in a new era for nanoscale imaging. Working at the U.S. Department of Energy (DOE)’s Lawrence Berkeley National Laboratory (Berkeley Lab), a collaboration of researchers used low energy or “soft” X-rays to image structures only five nanometers in size.

Ommaditias' Nanonipples Complicate Analysis of Common Fly’s Compound Eyes

In our vain human struggle to kill flies, our hands and swatters often come up lacking. This is due to no fault of our own, but rather to flies' compound eyes. Arranged in a hexagonal, convex pattern, compound eyes consist of hundreds of optical units called ommatidia, which together bestow upon flies a nearly 360-degree field of vision.

Scientists Test Silicon-Based ‘Photonic Crystal Nanocavity’

Unlike electronic circuits, optical, or "photonic", circuits work with light rather than electricity, which makes them 10 to 100 times faster. They are also more energy-efficient because they show lower heat loss, better signal-to-noise ratios and are less susceptible to interference. Used especially for communications (e.g. fiber optics), optical circuits may use tiny optical cavities as 'switches' that can block or allow the flow of light, similarly to transistors in electronics.

NIST Technique Enables Optical Microscopes to Measure 3D Shapes at Nanometer-Scale Resolution

Recent experiments have confirmed* that a technique developed several years ago at the National Institute of Standards and Technology (NIST) can enable optical microscopes to measure the three-dimensional (3-D) shape of objects at nanometer-scale resolution—far below the normal resolution limit for optical microscopy (about 250 nanometers for green light).
