A Magic Police story because those two helpless dorks are absolutely adorable!
Summary: Taken prisoner in the Magic Police station, four of the five Most Wanted must coexist with both each other and the two officers. Things don’t always work out peacefully, and sometimes the mages turn to battle.
Rythian’s scream broke through the early morning silence that had settled over the Magic Police station.
Graphene With Nanosized Holes Could Make Dramatically Better Water Filters
by Txchnologist staff
Tiny filters measuring just one-atom thick might be the next generation of technology that efficiently separates salt and impurities from water. Researchers report that they have successfully punched subnanoscale holes in graphene, the sheets of bound carbon atoms known to be one of the strongest materials on Earth.
They fired metal ions at the graphene to disrupt the bonds between carbon atoms, which naturally form into hexagonal rings that look like chicken wire. The graphene was then etched with a solution that dissolved the weakened bonds and formed densely packed pores.
“We bombard the graphene with gallium ions at high energy,” said Sean O’Hern, an MIT graduate student who led the research, in a university statement. “That creates defects in the graphene structure, and these defects are more chemically reactive.”
In Significant Advance for Artificial Photosynthesis, a Machine and Living Bacteria Work Together to Make Fuel
Scientists say they have merged living organisms with nanotechnology to mimic the photosynthesis plants use to make energy.
Blending chemistry, biology and materials science, the team from the University of California, Berkeley and Lawrence Berkeley National Laboratory created a living-synthetic hybrid system. The process brings together nanowires and bacteria (seen in the image above) to convert sunlight, water and carbon dioxide in the air into valuable chemicals like liquid fuel, plastics and pharmaceuticals.
Like plants, the system uses solar power to make complex molecules from simple ones. In contrast to the carbohydrates and oxygen that are the product of natural photosynthesis, the new device converts CO2 into acetate, which is the building block for a number of industrially useful chemicals.
“We believe our system is a revolutionary leap forward in the field of artificial photosynthesis,” said Peidong Yang, a Berkeley Lab chemist who was one of the project leaders. “Our system has the potential to fundamentally change the chemical and oil industry in that we can produce chemicals and fuels in a totally renewable way, rather than extracting them from deep below the ground.”
Concern and speculation about battery life had been building for months before yesterday’s launch of the Apple Watch. Up to a few days ago, when information started leaking in advance of the device’s release, rumors were flying that it wouldn’t last through a day’s normal usage before needing to be recharged.
The good news for Apple enthusiasts is that the company seems to have pushed energy efficiency to the point where the watch won’t bow out before the sun goes down. But what if this wearable tech, or the myriad others coming down the pipe, didn’t ever need to be plugged in to get its electron tanks topped off? What if the device could get what it needed by harvesting the energy in a user’s movements?
We’ve reported on a number of projects whose goal is to make generators that take advantage of the triboelectric effect, an electrical phenomenon where two different types of materials create a charge when they rub together. Imagine capturing the hundreds of volts generated when you walk across a carpeted floor in sneakers and throwing it into your phone battery for later use.
Now researchers in South Korea and Australia say they have built an energy-generating cloth that uses the triboelectric effect to generate power for wearable electronics.
