‘Nano-Earthquakes’ Result in Faster Electronic Components

Scientists from the Royal Melbourne Institute of Technology are working towards rocking the world of electronics. According to researchers Dr. Sumeet Walia as well as Dr. Amgad Rezk, the main key to connect the power of 2D materials lies under the Nano-earthquakes. They added that they have been able to find that the sound waves, if properly controlled will be able to influence the electronic properties of 2D materials such as graphene.

What are these earthquakes? 

The earthquakes as being referred by the researcher are no way linked with the actual earthquakes creating havoc around the world. But they are referring this to so called SAWs, which are surface acoustic waves, with the ability to circulate through a material. The researcher used this material as a source of photoluminescence rather than a semiconductor.

They took a layer which was coupled with several atoms to a substrate to understand the behaviour of SAWs rippling across the surface of the material. According to the experiment conducted by the researchers, they have utilized molybdenum disulfide, which is a quasi-2D material, with the ability to act as a semiconductor just like silicon.

The team was further able to modulate the electronic properties of the 2D material by controlling the intensity as well as direction of the ripples throughout the experiment. This research shed critical light on the relationship existing between the electronic performance of the molybdenum disulfide layer and the nano-quakes. Researchers found that with the increase in the intensity of the ripples, there was an increase in the photoluminescence property of the 2D material. More number of ripples led to the emitting of light from the layer.

What is the use of this technology? 

Scientists believe that the sound waves starts acting like the carriers of electrons and there by dragging them throughout the surface of the material as they are circulating. This is the main reason for change in the electronic property of the material. This ensures that the electrical conductance of the material is constantly increased till the time system is active.

The researchers believe that this technology will have lot of uses in the near future in terms of 2D materials, mainly towards the opto-eletric applications. A simple example is the camera quality in the Smartphone. The cameras of the Smartphones are often criticized for their low quality and poor adaptation to the dark due their small sensor size. Just image having a smartphone having a sensor made out of the 2D material which will increase the sensitivity of the lenses in the darkness by using the sound waves in the camera module. The manipulation of the sound as well as the 2D materials can certainly lead to an improvement in the solar panels as well.

As per the RMIT research team, increasing desirability of 2D materials has made this technology very strong and robust. They added that once the acoustic vibrations were stopped during the experiment, the molybdenum disulfide layer of the material regained its unique electronic state and no damage was seen in the material.

Discover Asteroids for NASA with This Free App

Now everybody will be able to help NASA by identifying new asteroids for them. Asteroid tracker desktop software has been released by the space agency today at the southwest today. This software has been released in collaboration with the Planetary Resources, which is an asteroid mining company. This conjunction happened through an online competition.

The new Asteroid Tracker Software: 

Reports suggest that this software has the ability to run on any standards PC and MAC. The software will be able to capture images from a telescope and in turn run it through an algorithm and thereby determine as to why some of the celestial bodies are on par and consistent with the asteroid behaviour.

Asteroid Data Hunter App: 

The Data Hunter app enabled with the Asteroid tracker software can be easily installed on any MAC computer or personal computer. The Online competition, which resulted in the development of the new app, was ended in December. This hunter app, however, requires the astronomers to have a little experience about the astronomy to operate it efficiently. Any original images captured from this new app can be reported out to Minor Planet Centre for further confirmation. This app can be downloaded on Topcoder.

The New Algorithm: 

The space agency claims that this new algorithm has been their biggest achievement. The agency reported that compared to the previous version, this new algorithm has the capacity to spot 15% more asteroids in the asteroid belt located between Mars and Jupiter. Another advantage of the algorithm is not only limited to the identification of asteroids in the space, but it can also endeavour to match these asteroids with the NEOs (near-Earth objects). Any amateur astronomer by means of this new app will be able to examine images which have been taken from the telescopes. These amateur astronomers can also send any of these images which match with the asteroid to be considered as part of the NASA database.

Benefits of the new algorithm: 

NASA seems to have been struggling with the increasing number of NEOs swirling around the earth and this new algorithm can be quite useful for handling this complicated situation. Through this efficient algorithm, the space agency will be able to track down possible asteroids which can be threatening to our Earth. Through this new app and contribution of astronomers, the agency will be able to sort out possible candidates for future missions related to asteroids.

NASA has been very much interested in locating space rocks that can be harmful to Earth from a very long time. The space agency is also hopeful of redirecting an asteroid and further placing it in moon’s orbit. This is expected to happen in the next few decades, post which the agency is hoping to send astronauts to further study this space. They are planning to carry out this process by means of Orion spacecraft as well as the space launch system. The space agency understands that there is immense mineral wealth in a single asteroid.

Scientists Precisely Control Gold-Coated Nanoparticles with Lasers

Undeniably humans will quite soon be considered as nano-particles making them the very first life-size nanotechnology, which has been built from the scratch. Now human seems to be looking forward to return a favour pertaining to this aspect by developing a nano-scale machinery from top to down. Even though the technological world is still waiting for this dream to become a reality, looks like a less glamorous micro and nano particle technology seems to be stealing all the limelight. Although there are many kinds of particles that are used for creating finely separated spheres and powders, gold has become come out as winner in terms of being the premier element mainly due to its properties related to opto-electronics.

Reports suggest that researchers from Munich have been able to use this, currently named as ‘plasmonic gold’ to create what they claimed to be is a micro-scale photonic elevator. They stated that a lot of experiments can be done by hitting out flecks of gold through various rays of energy. These beams of energy include fluorescence, precision thermal control, and movements in 2D plane however the researchers also added that this photonic elevator is however in control of their third axis.

The Plasmon: 

An oscillation of free electrons has been termed as the Plasmon. The electron density inside the electromagnetic radiation of wavelengths can couple with the plasmonic nano-particles making it larger than the particle itself. Researchers have been trying to find out as to what differentiates these particles created by the Plasmon over the surface of any interface unique in terms of their absorbance as well as scattering properties. The Plasmon derives these properties from their shape and sizes. In simple terms, the interaction of the Plasmon with the different radiation as well light is not only dependent on their elements but they are also affected by the geometry as well as the relative positioning of other particles inside them.

Lasertrap is one such device which has been able to capture the essence of the nano-particles technology. Using this device along with different kinds of microscope will allow anyone to feel the nano. The researcher created the so called magic by coating the half of the silica beads with a thermally collected gold vapour. They stated that due to this asymmetric gold coating, the Plasmon started showcasing scattering effects by orienting the particles inside the axis of the laser light. Using the gold coating has allowed the researchers to use the benefits of opto-genetics, without the need of any real genetics.

This is the kind of technology which is being anticipated by the scientists of the National Brain initiative to research the entire brain. The gold coating and its associated effects can be highly beneficial for conducting local calibrations and to collect feedback. Emergence of these electromagnetic technologies means using the same hardware with minimum changes and getting the best possible stimulation, images, therapeutic treatments. At the end, any equipment enabled with this technology will be the dream of any neuronaut.

Gamers Targeted By Ransomware Virus

A computer virus has been targeting the gamers around the world. The virus has the ability to stop the gamers from playing out their favourite games unless they are ready to pay a ransom for the same. Once a machine gets infected by the virus, this cruel program has the ability to seek out the saved games and other important files on the user’s computer and go ahead with encrypting the data. Reports suggest that in order for a user or the gamer’s to unlock any of their encrypted files, they will have to be ready to pay nearly $500 (£340) in Bitcoins. This malware has the ability to target nearly 40 separate games which include World of Warcraft, Call of Duty, World of Tanks, and Minecraft.

Dark world of the web and cash: 

This malicious program is very much similar to that off the widely distributed Cryptolocker Ransomware. It is the same Cryptolocker Ransomware which has been able to target thousands of people around the world in the last few years. However post the analysis of this malicious program called as Teslacrypt, it was revealed that it bears no resemblance or code share with Cryptolocker. Reports suggest that this program seems to have been created by a totally different cybercrime group.

According to the Vadim Kotov, a researcher from the security firm Bromium, the malicious file was targeting people by means of a website which has been already compromised by the creators. This site consists of a Wordpress blog that is unintentionally hosting a file that is making use of drawbacks in the Flash for infecting the potential visitors.

What happens when a machine gets infected? 

According to Kotov, post the infection of the machine, this malware has the ability to check out nearly 185 different file extensions in the user’s system. This malware, particularly looks out for files which are linked with popular video games and online services. These games need not belong to the top listing games on the web. He further added that the Teslacrypt malware, has the ability to store the files of the gamers which includes their maps, profiles, and saved games. He also added that gamers will only end up being disappointed if they try to uninstall any game downloaded through any online service. He further added that it is not possible for the user to restore any of their required data post re-installing the game file as well.

So what happens next? 

Once the user’s files have been targeted and encrypted by this malware, they will get a pop up message indicating that they have been targeted and they have only a few days to make the payment in order to retrieve their data. Reports suggest that the victim might end up paying between $500 to $1,000 Bitcoms in PaypalMy Cash payment cards. The Teslacrypt virus directs the potential victims to send their payment details to a designated address on the Tor anonymous browsing network. Although there are works in progress to crack the encryption system of the virus, user can resort to backups of the files in the meantime.

Youtube May Launch Subscription Video Service, Will Offer Ad-Free Streaming

According to some of the reports, it is believed that YouTube might be considering to opt for a subscription for their original contents. Reports published on the Verge indicate that the company is exploring the idea of launching its own subscription based VOD service. This is mainly due to the sudden boom in the world of technology wherein video streaming has been able to replace the conventional televisions and radios. Reports also suggest that the company is planning to rope in its YouTube stars for developing videos under their original banner.

What is the service all about? 

The new service is expected to be completely ad free towards the videos which have been created under the company’s original banner. The increase in the market competition and competitors like Vessel, Hulu among others, this move seems to be a push force for the company to innovate to stay in the competition. One of the most important benefits that can be expected by the company is the amount of profits it can generate for their video creators through the paid subscription.

The company even though started nearly a decade ago has been able to break out of their traditional means of offering videos to the customers. Reports suggest that the company has been facing a lot of difficulty in terms of generating revenues and unable to attract viewers due to greater than before use of ad-blocker programs.

Recent changes made by YouTube: 

The company has recently added complete support for 360-degree videos that have come to aid of the users who are used to a tremendous amount of video sharing and habituated to virtual-reality headsets. Reports suggest that Google has been working with some of the popular companies like Giroptic’s 360cam, Kodak’s SP360 and Bublcam among others, that are into making of the 360-degree movies and this collaboration will help YouTube to play these videos made their cameras. As if now this feature is expected to available on only certain devices, which includes iPad, iPhone among others.

What is the benefit for the company? 

The company always had the aim of making the conventional television outdated in the near future and looks like through this new project, they might soon be able to achieve their aim. Apart from the current project, the company also has many other projects in the pipeline. The rumor about the current project was spread from an unnamed executive at YouTube, who is currently working with the company for developing and producing video content.

Reports also suggest that the company is looking forward to create an original series, which is on the similar lines as that of Netflix. If the company is able to release this service, it will be similar as that of YouTube Music Key. The YouTube Music Key provides users access to ad free videos apart from free streaming of music from Google play music. The user is expected to be charged around $10 every month for using the service.
