Temperature-based Method May Improve Detection of Skin Cancer
QUEBEC CITY, Nov. 24, 2021 — An imaging technique developed by researchers at the Institut national de la recherche scientifique (INRS), can measure temperature in 2D, without contact, and in real time. The method could improve photothermal therapy and help deliver early diagnoses of skin cancers. The technology — single-shot photoluminescence lifetime imaging thermometry (SPLIT) — is based on the luminescence of nanoparticles doped with rare earth ions. “These nanoparticles are considered as

Opsens to Develop System for PTRC
QUEBEC CITY, Oct. 18, 2010 — Fiber optic sensor supplier, Opsens Inc., has been chosen by the Petroleum Technology Research Centre (PTRC) to design and construct a state-of-the-art transient pressure testing system for the assessment of well integrity in existing wellbores. ...
Temperature Sensors: Monitoring the Health of the Production Line
Oct 8, 2010 — For manufacturers, temperature can be a critical indicator of the status of a piece of equipment, a process or the product itself. Infrared sensors can be used as a useful yardstick to gauge the health of a production line, helping to maximize...
Image Sensors Made for Extreme Temps
DUISBURG, Germany, Sept. 23, 2010 — Car manufacturers are increasingly equipping their vehicles with image sensors to register the presence of pedestrians or vehicles in the blind spot or to detect obstacles when parking. The sensors must be able to function in extremely high...
Dark Current in Consumer Cameras: Not What you Expect
Sep 17, 2010 — By Ralf Widenhorn, professor; Justin C. Dunlap, graduate student; and Erik Bodegom, professor and chair, Department of Physics, Portland State University Since the advent of digital cameras, astronomers have known and struggled with dark current in...
Queen’s University Selects Linkam Stages
TADWORTH, England, Aug. 20, 2010 — For 10 years, Linkam Scientific Instruments has been used as temperature stage suppliers to Queen’s University in Canada to study the properties of ferroelectric liquid crystals. The research program, led by Professor Robert Lemieux and his...
Touchless Sensors on the Horizon
WÜRZBURG, Germany, March 25, 2010 — The cell phone is switched off but immediately springs into action at the point of a finger. It is not necessary to touch the display. This touchless control is made possible by a polymer sensor affixed to the phone which, like human skin, reacts to...
MOCVD Systems Meet LED Demand
Mar 23, 2010 — Explosive growth in the backlighting market for televisions, displays, handheld devices and more is creating a ripple effect throughout the LED industry. LEDs are sought after for backlighting because of their proven performance, low power...
Peptides do windows
Mar 18, 2010 — Nobody really likes washing windows. And dirt and grime – the kind you find on windows – are the bane of a solar panel’s existence. The good news is that a group of researchers at Tel Aviv University in Israel, which set out originally to find a...

Some Like It Hot
DUISBURG, Germany, Jan. 4, 2010 -- Normally, microelectronic chips designed to take pressure readings are very delicate. But a new technology developed at the Fraunhofer Institute for Microelectronics Circuits and Systems (IMS) makes them robust enough to continue operating normally...
Calibrating the Thermal Camera
Dec 1, 2009 — Thermal imaging, once the domain of the defense sector, is finding applications in a number of commercial and medical fields. As more manufacturers join the thermal camera business, the need to test these devices to recognized standards is becoming...
Silicates Get Denser When You Go Deeper
Aug 1, 2008 — Far below the Earth’s surface, where pressure and temperature escalate ferociously at the border between the mantle and the core, lies the history of primordial chemical differentiation. Molten silicates, such as MgSiO3 melts, likely comprised a...
Fiber Polarizer for Telecom Application
Jun 1, 2007 — Polarizers often are required for fiber optic communications, but those fabricated in fibers usually have a self-defeating temperature dependence. Bulk optical polarizers, the alternative, are large and awkward to integrate into telecom systems,...
Quantum Hall Effect Observed at Room Temperature
TALLAHASSEE, Fla., & NIJMEGEN, Netherlands, Feb. 20, 2007 -- The world's most powerful magnets have given an international research team a first-time look at the quantum Hall effect at room temperature. A better understanding of the quantum world can help scientists develop better ultrasmall electrical...
