Solar panel with 40% more efficiency

Specialists from UNSW Engineering have figured out how to accomplish more than 40 percent productivity in business sun powered boards - the most astounding proficiency rate ever reported.

"We utilized business sunlight based cells, however in another way, so these effectiveness enhancements are promptly open to the sun oriented industry," included Mark Keevers, who deals with the undertaking.

The world-record rate was accomplished by sun based boards tried outside in Sydney, Australia, and was then affirmed autonomously via scientists utilizing them as a part of the US.

"This is the most noteworthy proficiency ever reported for daylight change into power," said UNSW Engineering Scientia Professor and Director of the Australian Center for Advanced Photovoltaics, Martin Green, in a press discharge.

At this moment, the most proficient sunlight based cells are just changing over around 33 percent of daylight into power. However rather than simply utilizing one sun powered cell, the new innovation lives up to expectations by part daylight into four separate cells.

It additionally utilizes a custom optical bandpass channel to catch daylight that is typically squandered - the channel lives up to expectations by reflecting specific wavelengths, while transmitting others.

These cells were then utilized on a sun powered tower - a set-up that uses Sun-following mirrors to center daylight onto a sun oriented board secured tower - where the record-breaking productivity rate was recorded.

The model gadget will now be utilized by Australian organization Raygen Resources to construct "force towers" trying to make less expensive and more effective sun oriented vitality.

Green is additionally trusting that later on these cells will be utilized as a part of roof sun oriented boards, which at this time just have an effectiveness rate of around 15 to 18 percent.

"The new comes about are focused around the utilization of centered daylight, and are especially pertinent to photovoltaic force towers being produced in Australia," said Green in the discharge.

"The boards that you have on the top of your home, right now they simply have a solitary cell however in the long run they'll have a few diverse cells... also they'll have the capacity to enhance their effectiveness to this sort of level," he told AFP.

Green is sure that in 10 years, sun based force will be less expensive than vitality created by coal, he clarified to AFP.

Device to find your veins

While donating blood, a lot of doctors experience the difficulty in finding the veins of donor. Some doctors use jabber at your arm to hold the flow of blood in your arm for a couple of minutes because they couldn't find out your correct veins.

 The Australian Red Cross is the first blood bank service in the wold to trials this device.
Keeping this problem in mind, scientists have made a new device that will help doctors in finding your veins as well as relieving you from the pain of jabber.

The device works by beaming harmless infrared light at donor's arm. As our veins contain a lot of de-oxydenated hemoglobin, it created the image of exactly where your veins are under the skin. 

Moreover, this device can be used anywhere without any hazards. Hospitals and pathology clinics are using widely using this device to make it easier for doctors and well as for their patients.

Eel-like robot to assist divers

Due to superior flexibility of Anguilliform fishes, scientists in Singapore developed a prototype of an eel-like robotic fish to allow marine forces to reach such areas which are much difficult or impossible for the divers to reach.

The Anguilliform robotic fish is small, sophisticated and elegant enough to operate autonomously underwater.


"We performed simulations and experiments on the robotic fish, equipped with a motion library to cope with different scenarios, and the results validate the effectiveness of the proposed controllers as it was able to swim forward and backward as predicted," said Jianxin Xu from the National University of Singapore and co-author of the project.

Hackathon fights Ebola outbreak

Ebola- the fatal disease that has took the lives of million of people and is out breaking speedily. To fight with such a deadly virus, besides health workers and fast track vaccines, software developers are also contributing their work in such a war.
To help West African communities, who are getting ruined by such disease, Ebola Crisis Hackathon is developed with the help of various students and physicians at the University of Oxford earlier this month.

Describing the infrastructure of the system, Paul Brodersen, a researcher, describes one of the tool which automatically detects affected people appearing in a video and measures their pule using image analysis. To achieve this goal, a technique named Eulerian Video Magnification is used. It works even with a simple webcam. It works by amplifying the red tones in a person's face. The insidious variation in redness over time gives the pulsing of blood.

Gorilla Glass 4

The new "Gorilla Glass 4" ,will be two times harder than any mobile cover glass which is now available in the market. It will really help those people who accidentally and circumstantially drop their phones, which results screen smashing.

 The Dropping and breaking phone is a common and serious  problem.To solve this ambiguity scientists make many experiments.Corning says that scientists break more than hundred devices during the development of Gorilla Glass 4. What they found that smartphones will never break most when their screens make contact with hard and rough surfaces .That sound unspeakable. I mean you guys will definitely wont believe this but it is true.Some how using this technique they end up with this product.

We expected to have this feature in all coming smart phones and tablets including the Iphone series.

Robots- Controlling e-waste

Every year, a massive amount of electronic-waste (e-waste) is thrown out in Australia and the amount increases day by day. To tackle this problem, researchers from University of  New South Wales (UNSW) have programmed industrial robots to get this job done.

It is a collective project by researchers at School of Mechanical and Manufacturing Engineering's Sustainable Manufacturing and Life Cycle Engineering Research Group (SMLCE) and the school of Computer Science and Engineering.

Researchers showed that robots can memorize the assembling and disassembling of electric product so that they can use this technique for the recycling of such products at increasing speed.

SMLCE founder and project Professor Sami Kara said that there are tons of end-of-life products that we don't know how to disassemble, despite legislation tells us to do so. "The biggest problem is uncertainty - the number of different products coming into electronic recycling centers and their condition", he said.

Tracking your meal- Bluetooth Tracker

   

             For the people who are curious, and want to monitor their diet more accurately, a new technology in on the ground which has became a real companion for them.

To keep track of the diet that you have taken is not comfortable in a normal routine of a person. Many fitness tracking apps demands such a track of diet and the components that you've taken in diet because they couldn't have an accurate answer of how healthy and quantity of a food is.
