Engineers design nanostructured diamond metalens for compact quantum technologies

Tue, 06/11/2019 - 22:51
By finding a certain kind of defect inside a block of diamond and fashioning a pattern of nanoscale pillars on the surface above it, engineering researchers can now control the shape of individual photons emitted by the defect. Because those photons carry information about the spin state of an electron, such a system could be used as the basis for compact quantum technologies.

Thwarting oil-pipeline corrosion by identifying a nanoscale villain

Thu, 06/06/2019 - 21:37
Certain molecules of iron, when juxtaposed, have been found by researchers to cause microscopic holes in steel pipe used for oil transport. This hidden, localized corrosion causes oil pipes to rust unpredictably at rates faster than baselined, interfering with the accuracy of computer models that determine pipe replacement schedules. This problem, which is potentially environmental, may be addressed by changing the microstructure of the steel surface during forging.

Manipulating nanoscale light in nanocavity of scanning tunneling microscope junctions

Thu, 06/06/2019 - 18:18
Manipulating nanoscale light in scanning tunneling microscope junctions is attained by nanofabrication of gold tips using a focused ion beam technique. Researchers have demonstrated that a spectrum of 'nanolight' in a nanoscale plasmonic junction can be modulated with plasmonic Fabry-Pérot tips. Precise control of nanolight is of key relevance to nanoscale imaging and spectroscopy to investigate structure, dynamics, optoelectronic properties of nanomaterials and single molecules.

DNA nanorobots target HER2-positive breast cancer cells

Wed, 06/05/2019 - 18:04
About 20% of breast cancers make abnormally high levels of a protein called human epidermal growth factor receptor 2 (HER2). When displayed on the surface of cancer cells, this signaling protein helps them proliferate uncontrollably and is linked with a poor prognosis. Now, researchers have developed a DNA nanorobot that recognizes HER2 on breast cancer cells, targeting them for destruction.
