Tunable Single-Photon Emitter Could Empower Quantum Info Processing
Tunable Single-Photon Emitter Could Empower Quantum Info Processing
Carbon nanotube quantum light emitters have been produced that are capable of single-photon emission at room temperature and at telecommunications wavelengths. These emitters could be used for optically based quantum information processing and information security as well as for sensing, metrology and imaging. Critical to the success of the project was the ability to force the nanotube to emit light from a single point along the tube, specifically at a defect site.

Flat Microscope Will Be Used in Implantable Neural Interface
Flat Microscope Will Be Used in Implantable Neural Interface
A prototype of a flat microscope, called FlatScope, has been developed as part of the Defense Advanced Research Projects Agency’s (DARPA’s) Neural Engineering System Design (NESD) project. The microscope will be designed to sit on the surface of the brain, where it will detect optical signals from neurons in the cortex. The ultimate goal of the NESD project, which includes research teams from the U.S. and Europe, is to develop an alternate path for sight and sound to be delivered directly to the human brain.

New Method Promises Easier Nanoscale Manufacturing
New Method Promises Easier Nanoscale Manufacturing
A new method to precisely pattern nanomaterials could open a new path to manufacturing next-generation electronic devices. Scientists at the University of Chicago (UChicago) and Argonne National Laboratory say their discovery could make building nanomaterials into complex structures for uses in LED displays, cellular phones, photodetectors and solar cells much more attainable.

Imaging Tracer Could Allow Early Risk Assessment of Abdominal Aortic Aneurysm
Imaging Tracer Could Allow Early Risk Assessment of Abdominal Aortic Aneurysm
With the development of a novel tracer, single-photon emission computed tomography/computed tomography (SPECT/CT) imaging could potentially be used to assess a patient’s rupture risk for abdominal aortic aneurysm (AAA), allowing better management of this disease.

Laser-Based Weeding Supports Sustainable Agriculture
Laser-Based Weeding Supports Sustainable Agriculture
A smart system for controlling invasive weed growth uses multispectral sensors and computer vision algorithms to detect and classify all plants in a field. After weeds are identified, a laser beam is used to eliminate or seriously damage the weeds. Sensing cameras are attached to an all-terrain robot or even a tractor add-on to find and target unwanted weeds.
