Self-Charging Battery Could Make Chargers Obsolete

New technology developed by Hydro-Québec and McGill University is capable of harvesting and storing energy using light – a self-charging battery. To create the light-charged batteries, a standard cathode from a lithium-ion battery can be “sensitized” to light by incorporating photo-harvesting dye molecules.

New Device Harnesses Heat to Power Computers

The thermal diode may allow computers to use heat as an alternate energy source. (Karl Vogel/Engineering)

One of the biggest problems with computers is keeping them cool so they don’t overheat. University of Nebraska–Lincoln engineers developed an alternative energy source that would allow computing at ultra-high temperatures. The nano-thermal-mechanical device, or thermal diode, could be used in space exploration, for exploring the core of the earth, for oil drilling, or in applications requiring calculations and data processing in real time in places where computers have not been able to function.

Architectures for Implementing a Hardware-in-the-Loop System

Safety, availability, or cost considerations can make it impractical to perform all the necessary tests with the complete embedded control system. Using hardware-in-the-loop (HIL) simulation, you can simulate the parts of the system that pose these challenges. By thoroughly testing the embedded control device in a virtual environment before proceeding to real-world tests of the complete system, you can maintain reliability and time-to-market requirements in a cost-effective manner even as the systems you are testing become more complex. Download this whitepaper to find out more about implement a HIL system into your test environment.

Building Better Bonds

Until recently, there was little up-to-date research about adhesives that could be used with Eastman Tritan™ copolyester. By collaborating with Henkel Corporation, whose LOCTITE® adhesive continues to be tested at the industry’s most comprehensive ISO 10993 biocompatibility standards, Eastman was able to determine which combination of resins and adhesives could help optimize a manufacturer’s assembly process. Results proved that Tritan, together with LOCTITE® adhesives, provides improved process efficiency for a wide range of medical devices.

In outdoor locations, firefighters and emergency responders can use GPS technology to track one another. Indoor environments like high-rises and steel-reinforced structures, however, frequently block radio signals. With the development of POINTER (Precision Outdoor and Indoor Navigation and Tracking for Emergency Responders), Darmindra Arumugam has addressed the sensing challenge, and provided a potentially game-changing tool for search and rescue teams.

Is Pluto a Planet? Scientists Seek New Definition

In 2006, the International Astronomical Union demoted Pluto to "non-planet" status. Johns Hopkins University scientist Kirby Runyon led a group of six researchers to draft a new definition of "planet" — one that includes more than 100 other celestial bodies, including Pluto. The proposal was presented at the Lunar and Planetary Science Conference, hosted in Houston, Texas on March 21.

Logistics for Building Radiation Storm Shelters and their Operational Evaluation

Various habitat structures were tested for use in exploration activities.

Over the past three years, NASA has been studying the operational effectiveness and astronaut protection efficacy of numerous radiation protection shelters for use in space exploration activities outside of Earth's magnetosphere. The work was part of NASA's Advanced Exploration Systems (AES) RadWorks Storm Shelter project. Fabricated items were integrated into mockup deep space habitat vehicle sections for operational evaluations. Two full-scale human-in-loop simulations were designed, fabricated, and implemented. The goal was to provide design and performance assessment information for consideration by mission designers who must quantify the radiation protection characteristics of their exploration trade space.
