Fast-Charging Batteries Have 20-Year Lifespan

Scientists at Nanyang Technology University (NTU) have developed ultra-fast charging batteries that can be recharged up to 70 percent in only two minutes. The new-generation batteries also have a long lifespan of over 20 years, more than 10 times compared to existing lithium-ion batteries.In the new NTU-developed battery, the traditional graphite used for the anode (negative pole) in lithium-ion batteries is replaced with a new gel material made from titanium dioxide. Titanium dioxide is an abundant, cheap and safe material found in soil. Naturally found in spherical shape, the NTU team has found a way to transform the titanium dioxide into tiny nanotubes, which is a thousand times thinner than the diameter of a human hair. The development speeds up the chemical reactions taking place in the new battery, allowing for superfast charging.  The breakthrough has a wide-ranging impact on all industries, especially for electric vehicles, where consumers are put off by the long recharge times and its limited battery life.SourceAlso: Learn about a Screening Technique for New Battery Chemistries.

Is a sleeper ship our best bet to Mars?

At the Center for Research in Advanced Materials (CIMAV), scientists "captured" the energy produced by people walking. The team designed a pill-shaped cylinder adapted to a shoe in order to store the mechanical-vibrational energy that the person generates when walking. Similarly, the London-based company Pavegen produces a technology that harvests mechanical energy of walking feet and converts it to electrical energy via a special floor tile. Both ideas perhaps could lead to cities using the alternative, piezoelectric solutions to create power when and where it is required. What do you think? Will we harvest energy with our own footsteps?

Imaging System Obtains More Color Information than Human Eye

Researchers at the University of Granada have designed a new imaging system capable of obtaining up to twelve times more color information than the human eye and conventional cameras, which implies a total of 36 color channels. The important scientific development will facilitate the easy capture of multispectral images in real time.The technology could be used in the not-too-distant future to create new assisted vehicle driving systems, to identify counterfeit bills and documents, or to obtain more accurate medical images than those provided by current options.The scientists, from the Color Imaging Lab group at the Optics Department, University of Granada, have designed the new system using a new generation of sensors, in combination with a matrix of multispectral filters to improve their performance.Transverse Field Detectors (TFDs) extract the full color information from each pixel in the image without the need for a layer of color filter on them.In order to do so, the TFDs take advantage of a physical phenomenon by virtue of which each photon penetrates at a different depth depending on its wavelength, i.e., its color. In this way, by collecting these photons at different depths on the silice surface of the sensor, the different channels of color can be separated.SourceAlso: Learn about Imaging Space System Architectures.

Robots Restore Electricity After Power Outages

A team led by Nina Mahmoudian of Michigan Technological University has developed a tabletop model of a robot team that can bring power to places that need it the most.“If we can regain power in communication towers, then we can find the people we need to rescue,” says Mahmoudian, an assistant professor of mechanical engineering–engineering mechanics. “And the human rescuers can communicate with each other.”Unfortunately, cell towers are often located in hard-to-reach places, she says. “If we could deploy robots there, that would be the first step toward recovery.”The team has programmed robots to restore power in small electrical networks, linking up power cords and batteries to light a little lamp or set a flag to waving with a small electrical motor. The robots operate independently, choosing the shortest path and avoiding obstacles, just as you would want them to if they were hooking up an emergency power source to a cell tower.“Our robots can carry batteries, or possibly a photovoltaic system or a generator,” Mahmoudian said. The team is also working with Wayne Weaver, the Dave House Associate Professor of Electrical Engineering, to incorporate a power converter, since different systems and countries have different electrical requirements.

Coming Soon - PDM Solutions for Small SolidWorks Teams

Product data management (PDM) software can be overkill for small CAD teams. But without PDM you face the risks of losing track of your CAD models, overwriting models, and having users working on the wrong version of a model. So how can your team move from email and FTP to a PDM system that makes sense for SolidWorks users?
