Sanyo is about to add some new additions to its eneloop universe series of portable power ...

Since introducing its eneloop rechargeable battery technology in 2005, Sanyo is reported to have shipped over 130 million cells. Now the company has announced some new additions to its eneloop universe series which provide a power boost to a host of mobile devices including Apple's iPad, Sony's Xperia smartphone and Nintendo's DS series portable gaming devices.  Read More

Researchers from the University of Michigan have unveiled a more efficient, brighter and h...

Only a small percentage of backlight actually makes its way out through the multiple layers that make up the ubiquitous LCD displays we use today. That may change with the development of new filter technology at the University of Michigan. White light is sent through tiny, precisely spaced gaps on nano-thin sheets of aluminum and is said to result in brighter, higher definition color reproduction. Other benefits of the technology include efficiency gains and simpler manufacturing.  Read More

ORNL's James Klett with his LED-cooling graphite foam

LED lamps may soon be able to go much longer between fixture replacements thanks to a new graphite foam cooling system developed at the US Department of Energy's Oak Ridge National Laboratory (ORNL). The graphite foam works by passively wicking heat away from the lamp via its lightly-packed, open skeletal structure – and given that a ten-degree decrease in operating temperature can double the lifespan of LED lighting components, the benefits of keeping them cool are clear.  Read More

A homemade laser microscope has revealed the very lively, secret life of a drop of water

Some burning questions have just got to be answered, no matter the substantial costs involved. One such question demanding attention is: can a laser pointer be used to examine the microscopic contents of a drop of water? Happily, the answer is yes, and without the aforementioned prohibitive expense. In this home experiment, a laser pointer was shone through a drop of water collected from the base of a potted plant and the magnified image projected on an opposing wall. Read on to see a video showing a bemused-looking cat watching the resulting light show.  Read More

The spintronics breakthrough by Hui Zhao could lead the way to the development of superior...

Spin electronics, or “spintronics” promises to revolutionize computing. We’ve covered numerous breakthroughs in the field including controlling the spin of electrons, manipulating single electrons independently, and the first plastic spintronic computer memory device. However, one major hurdle for spintronics researchers has been the difficulty in detecting the flow of spinning electrons in real time. The discovery of a new way to recognize currents of spinning electrons within a semiconductor changes that and could lead the way to the development of superior computers and electronics.  Read More

Drexel University's Dr. Yury Gogotsi (right) and colleagues have developed an ultrahigh-po...

Supercapacitors, also called electric double layer capacitors (EDLCs) or ultracapacitors, are electrochemical capacitors that have an unusually high energy density when compared to common capacitors. They bridge the gap between batteries, which offer high energy densities but are slow, and “conventional” electrolytic capacitors, which are fast but have low energy densities. An international team of researchers are reporting the development of a mirco-supercapacitor with remarkable properties that has the potential to power mobile electronics, wireless sensor networks, biomedical implants, RFID tags and embedded microsensors, among other devices.  Read More

The iPADock provides a home for most, if not all, of your iDevices

Japanese company PhotoFast Co.,Ltd. is set to release the iPADock at the end of September, and if these first pictures (released this week) are any indication, it's quite possibly the most bad-ass iPad/iPhone charging dock we've seen to date. This docking station can accommodate various combinations of devices – you can connect two iPads at once, four iPhones at once, or you can mix it up with one iPad and two iPhones. You can also use iPADock to charge up your iPods, as it's compatible with the Touch, Nano, and Classic models as well.  Read More

Tiny flakes of lithium manganese phosphate can serve as electrodes for batteries (Image: D...

Rechargeable lithium ion batteries are used in everything from mobile phones to cars. Most of the batteries available today are designed with an oxide of metal such as cobalt, nickel, or manganese, which adds to their cost. Researchers looking for lower-priced alternatives to existing lithium ion-metal oxide batteries have discovered that a little wax and soap can help build electrodes and will allow battery developers to explore lower-priced alternatives to the lithium ion-metal oxide batteries currently on the market.  Read More

Motorola's new Bluetooth earpiece designed for secure communications

Motorola has launched three new "mission critical" communications devices aimed at law enforcement and first responder applications. The MVX1000 in-car digital video system and APX P25 two-way radio series are joined by the company's first encrypted Bluetooth earpiece designed for secure communications.  Read More

A first generation, self-calibratable MEMs that has been used to measure the Casimir force...

Micro electromechanical systems, or MEMs, are promising in an array of high-tech applications. However, the accuracy of conventional techniques to gauge the force and movement of tiny objects containing components so small they have to be measured on the scale of micrometers or nanometers are typically off by 10 percent or more because of their inherent uncertainties. A new technology enabling MEMs to "self-calibrate" could overcome this problem and make possible super-accurate and precise sensors for crime-scene forensics, environmental testing and medical diagnostics.  Read More
