New way to shape thin gel sheets proposed

Inspired by nature's ability to shape a petal, and building on simple techniques used in photolithography and printing, researchers at the University of Massachusetts Amherst have developed a new tool for manufacturing three-dimensional ...

High-speed CMOS sensors provide better images

Conventional CMOS image sensors are not suitable for low-light applications such as fluorescence, since large pixels arranged in a matrix do not support high readout speeds. A new optoelectronic component speeds up this process. ...

Bright future for gaN nanowires

The gallium nitride nanowires grown by PML scientists may only be a few tenths of a micrometer in diameter, but they promise a very wide range of applications, from new light-emitting diodes and diode lasers to ultra-small ...

Researchers suspend, image single DNA molecules

(PhysOrg.com) -- Studying chemical modifications in the chromosomes of cells is akin to searching for changes in coiled spaghetti. Scientists at Cornell have figured out how to stretch out tangled strands of DNA from chromosomes, ...

UA engineers win patent for protein-based electronic circuits

(PhysOrg.com) -- University of Arizona engineers have patented a process that could lead to the next big leap in microelectronics, completely changing the way microchips are made. Pierre Deymier, a professor of materials ...

Spheres can form squares

Everybody who has tried to stack oranges in a box knows that a regular packing of spheres in a flat layer naturally leads to a hexagonal pattern, where each sphere is surrounded by six neighbours in a honeycomb-like fashion. ...

Brilliant dye to probe the brain

To obtain very-high-resolution 3D images of the cerebral vascular system, a dye is used that fluoresces in the near infrared and can pass through the skin. The Lem-PHEA chromophore, a new product outclassing the best dyes, ...
