Researchers at the University of Southern California, led by Professor Chongwu Zhou, replaced graphite with porous silicon nanoparticles in anodes of lithium-ion batteries to come up with a new design. The battery, which could be available in two to three years, has a longer life and charges more quickly than lithium-ion batteries used now. (Source: Mingyuan Ge & Chongwu Zhou/USC)
I'm confused. Although the title says that a longer-lasting battery was invented, the story says "Another weakness in the design is that the battery's lifespan isn't as long as traditional graphite-based design".
There is a lot of innovation happening in the battery space at the moment and, in my opinion, it couldn't come at a better time. If you think about it, while so much other technology has evolved in leaps and bounds, batteries historically have been very slow to evolve yet we are still quite dependent on them to power all of our gadgets and devices. The idea of a longer-lasting battery that can recharge so quickly is a welcome innovation in this space.
Enabling the Future is designing prosthetic appendages modeled more like superhero arms and hands than your average static artificial limbs. And they’re doing it through a website and grassroots movement inspired by two men’s design and creation in 2012 of a metal prosthetic for a child in South Africa.
In order to keep an enterprise truly safe from hackers, cyber security has to go all the way down to the device level. Icon Labs is making the point that security has to be built into device components.
Three days after NASA's MAVEN probe reached Mars, India's Mangalyaan probe went into orbit around the red planet. India's first interplanetary mission, and the first successful Mars probe launched by an Asian nation, has a total project cost of nearly $600 million less than MAVEN's.
Plant user interfaces are beginning to incorporate the consumer features such as swipe, double tap, and pinch. The driver is Millennials who expect plant equipment to match the sophistication of the smartphone.
