Caltech engineers build smart petri dish

The cameras in our cell phones have dramatically changed the way we share the special moments in our lives, making photographs instantly available to friends and family. Now, the imaging sensor chips that form the heart of ...

The fine art of etching

(PhysOrg.com) -- They see more than the naked eye and could make traffic safer: miniaturized thermal imaging sensors. But they are difficult to manufacture on a commercial scale. Researchers have now developed a new system. ...

Engineers create vibrant colors in vertical silicon nanowires

(PhysOrg.com) -- Engineers may soon be singing, "I'm going to wash that gray right out of my nanowires," thanks to a colorful discovery by a team of researchers from Harvard University and Zena Technologies. In contrast to ...

UV-transparent coating for image sensors

Image sensors as used in cell phones are partially color-blind. This is because of their coating, which prevents UV light from passing through. CMOS chips have as a result not been suitable for spectroscopy up to now. A new ...

Researchers train software to help monitor climate change

(PhysOrg.com) -- A computer program that automatically analyzes mounds of satellite images and other data could help climate scientists keep track of complex, constantly changing environmental conditions, according to an ...

Detecting drivers in microsleep with infrared LED

A new infrared light-emitting diode (IR-LED) from the Siemens subsidiary Osram Opto Semiconductors is designed to help recognize the hazardous microsleep that affects motorists. In addition to the IR-LED, this requires a ...

Image sensors for extreme temperatures

Image sensors which are used as electronic parking aids in cars or for quality control in production systems have to be able to withstand the often very high temperatures that prevail in these environments. Research scientists ...

Satellite data reveal seasonal pollution changes over India

Armed with a decade's worth of satellite data, University of Illinois atmospheric scientists have documented some surprising trends in aerosol pollution concentration, distribution and composition over the Indian subcontinent.
