The team at the university uses voxels and ultrasound waves to keep the pixels floating in mid-air. These pixels are actually floating in mid-air (via University of Sussex)


With most of our times spent staring at screens, the clear, crispness of displays are important. Every year devices seek out pixels that are better and make for the ultimate viewing experience. But what if the pixels floated in midair? The University of Sussex has created an experimental display, dubbed JOLED, made of a grid of voxels that measure 7x6 voxels high and wide. That’s not the mind blowing part. The voxels look like multi-colored spheres that float in mid-air.


Looking at the testing footage, it looks like a magic trick or CGI footage, but this is very real. The spheres stay in the air by ultrasound speakers that put out high-pitched and high intensity soundwaves, which are inaudible but forceful enough to keep the spheres in the air. The pixels themselves are coated in titanium dioxide, which gives them an electrostatic charge which allows them to be manipulated in mid-air with a change in the electric force field.


So what can this technology be used for? The team at Sussex is currently testing how the display can be used to provide on-demand media. They see it as a screen appearing in front of the viewer and then the objects fall to the ground once the video is finished. They also want viewers to be able to interact with it. Sounds like something out of The Matrix. The team also wants to up the pixel density along with the colors displayed.


It’s definitely cool to see these pixels float in the air looking like it was created with movie magic. But don’t expect to see the display for yourself anytime soon. The team still has a lot of work to do before they make this technology a reality. Recently, the team presented their findings at Japan’s ACM User Interface Software and Technology Symposium. This technology could lead to new possibilities for media, including mobile and game designers. 


Who knows, this is what our displays could look like in the future. For now, we’ll have to shell out a lot of cash for those flat old 4K TVs. Or.. is it time to dust off the CRT?

Can anyone help me on how to automatically  wake MFRC 522 Mifare Reader up by the presence of a RFID Card. And after goes back to sleep


Russian and European scientists believe T-rays will be faster than electromagnetic fields when running computers. Will T-rays make our computers faster?


No one looks forward to going to the airport and in recent years the experience has been more unpleasant thanks to TSAs. Security is important, but there’s a sense of dread and unease when walking through a body scanner. But while getting scanned to make sure you have the proper sized shampoo, did you ever think the TSA technology could be used to speed up your computer? Russian and European scientists are currently testing the method and published their findings in Nature.


No matter how fast your computer is, it can always be faster. Memory is what keeps our computers from being lightning fast. Memory cells on a PC are switched via an external magnetic field, but it’s not necessarily the fastest method. But this new process proposed by scientists would forego that. Rather it would use terahertz radiation (T-rays), the same ones found on airport bdy scanners. The T-rays could speed up the rate at which cells reset by a factor of 1000. This could then be used to make faster memory.


T-rays (Terahertz-driven anisotropy fields) emit a series of short electromagnetic pulses that hit the cells at high terahertz frequencies making them faster than the average electromagnetic field. But don’t expect to find t-rays blasting through computers any time soon. Scientists are still testing the method. So far they’ve tested it on a weak ferromagnet, thulium orthoferrite (TmFeO) with great success. The results also showed the T-rays’ effect was ten times greater than the external magnetic field making this method faster and more efficient. But the T-rays have yet to be tested on computer memory cells. You’ll have to wait on getting a super speedy computer.


Because T-rays can dish out quick, precise scans of organic and mechanical material, they have other uses as well. Some proposals include looking for weapons inside of luggage, scanning broken microchips, and looking into fragile texts. If this method does actually work on computer memory cells, it would be a huge improvement for high performance computers. Even the tiniest boost could make a big difference depending on the application. Scientists are still working out all the kinks but hopefully we’ll have an update on this development soon.

A research team at the University of Colorado-Boulder is using wastewater from breweries to help cultivate ion battery electrodes. A diagram of the process researchers use the wastewater (Photo from University Colorado-Boulder)


For some, beer is the ultimate refreshment, but thanks to researchers at the University of Colorado-Boulder, it can also be a power source. Researchers have found a way to transform brewery runoff into low-cost lithium-ion battery electrodes. Talk about getting a buzz. This is a great way to recycle the waste. When a brewery makes a single barrel of beer it takes around seven barrels of water to make it. The wastewater then has to be filtered before it’s thrown out, which also costs brewers money. Using the waste to cultivate batteries not only recycles the matter, but it saves money as well.


The process of using the wastewater for ion batteries is similar to beer making according to the Colorado researchers. They cultivate the feedstock in wastewater, which produces Neurosporacrassa, a fast growing fungus. This sugary fungus can then be used to make anodes for the ion batteries. The researchers say the wastewater is ideal for the fungus to grow in. The wastewater also helps researchers note the fungus' chemical and physical processes from the beginning.


Researchers are in the testing phases with the process now, but as long as tests prove successful it has the potential to be used on a wider scale. This process could help breweries limit their wastewater costs and manufacturers would have access to an incubating medium for battery technology components that are cost effective. So far, one brewery is one board with the research team: Avery Brewing in Boulder. This new partnership will allow the team to test the process on a wider scale. The team, led by Tyler Huggins and Justin Whiteley, recently took part in the finals of a US Department of Energy-sponsored incubator competition at the Argonne National Laboratory in Chicago.


Recycling wastewater to help ion batteries is a great step forward in helping to reduce waste on the planet. This process prevents the waste from just sitting in giant vats in the brewery. It also saves them money and happy breweries make for tastier beer, probably. Who would've thought beer could actually be used to make batteries. And you thought the best thing they did with beer is make fried foods with it.
