Graphene – a Material with Promising Superconducting Properties

Graphene – a Material with Promising Superconducting Properties

Graphene, the new shooting star among the stable carbon forms

For a long time, physicists have been bothering about what should follow silicon when the microelectronics based on this material reaches its end. The latest hope carrier is made of carbon and is neither a metal nor a Super conducting material – the Graphene

The super conducting material Graphene is always good for surprises. When the well renowned science magazine ‘Science’ in 1991 declared the C60 fullerenes consisting of 60 carbon atoms as the molecule, Japanese researchers had already discovered another stable form of carbon: the nanotubes consisting of coiled graphite layers.

However, the nanotubes are in danger of being overshadowed by a further modification of the carbon. Two and a half years ago Andre Geim and Kostya Novoselov of the University of Manchester succeeded in peeling off a graphite block from a layer of adhesive, until only a single atomic layer of graphite remained. This layer is one million times thinner than a sheet of paper. Thus, the researchers had achieved something which was previously considered impossible. For theoretical reasons it had been believed that two-dimensional crystals were not stable and would either clump or roll up. Graphene has excellent electrical conductivity as the group from Manchester continued to emerge. This prompted many researchers to look more closely at the material and its application potential in modern electronics.

If they are to be recorded with the usual terms, then it is neither a semiconductor nor a metal. The high conductivity of metals is due to the fact that there are always free electrons in them, which can be set in motion by an electric field. In a semiconductor, on the other hand, the electrons have to be lifted from the full valence band over an energy gap (the so-called band gap) into the conduction band so that they can flow as current. The peculiarity of the super conducting material Graphene consists in the fact that the two bands are not strictly separated from one another, but are touching at certain points.

This unusual band structure is due to the honeycomb like arrangement of the carbon atoms in the 2D crystal lattice. This results in a number of strange consequences. Thus the assert carriers in graphene show in some respects a behavior which is otherwise known only from particles which move approximately at the speed of light. This analogy is particularly fascinating for basic researchers.

Very recently MIT physicists discovered that a graphene flake, while brought in close propinquity among two superconducting materials, could acquire some of those materials superconducting attributes. As graphene being machinate between superconductors, its electronic state alters dramatically, even at its center. Visualized below is the brief data-based conception.

Their discovery, publicized few days ago in Nature Physics, are the prototypical research of Andreev affirms due to superconductivity’s “proximity effect” in a 2D material such as graphene.

In the near future, the researchers of graphene platform might be used to research exotic materials, such as Majorana fermions, that are greatly considered to spring up the important materials for building omnipotent, error proof quantum computers.

Build Lego With Chrome

Build Lego With Chrome

What is Build With Chrome?

Build With Chrome is a web application for Chrome that allows the user to creatively build realistic structures using Lego bricks. It’s a platform developed by LEGO and Chrome collectively, for people to build within Chrome’s browser. The creations are placed on real life geographical maps, so one might find a Lego model in Google Maps.

How does Build Lego With Chrome  Work?

For building a structure, two piles of Lego bricks are available and different keyboard and mouse commands can be used for controlling the build process. Later, a detailed build academy was added to help users get more creative which teaches the process and provides tips to build with Lego. Initially, the user has to share their location and is allotted a space that looks similar to a Lego baseplate. However, one can zoom in any chose any geographic are on which the entire Lego model will be based. In order to unlock additional bricks, the challenges have to be completed.

 

Other local models are also available on the world map and even Lego models of the actual structures can be found. Therefore, if all the structures in a town are built by different users, the entire town would get a Lego representation of its real-life version. While developing a Lego model, one designer can have only one baseplate and models can’t overlap pieces of another baseplate. There are a few technicalities to follow while building a model but all in all, it’s a great platform to showcase your creativity and build structures from your imagination in the virtual world.

Browse the map and find an open plot to get started and or have Build find you one by clicking the Build button which is blue in color. Every plot is a 32-by-32-peg square and a user is initially given 1,000 virtual Lego bricks to use. As you complete different Build challenges, you unlock more bricks to use further. The bricks are available in ten different colors and types with two extra types, a door and a window. You can make a selection from the left panel and then drop them on the right hand side. To place a brick, left-click on the plot and to move it, right-click on it. To align your bricks in the direction you want, use the rotate button in the left panel. By holding down the space bar while moving the mouse you can rotate your plot to view it better while working on a particular area. After your done working on it, you can publish your creation by clicking the green Publish button present in the upper-right corner of the screen.

 Lego

Sharing and Access

The models or creations can be shared and you can view models created by others through Google+. All models shared on Google+ are public and can be viewed by any Google+ user. Since the models are public, the creators’ Google+ names are also public. One can even view the geographical address of the model placed on the map. You can even share your model through email. However, for your model to be seen on the map, it needs to be approved first by Lego.

Any browser enabled with WebGL can access Build With Google Chrome. This includes Safari, Firefox and all types of mobile browsers. Once you select you choice of browser, WebGL’s site will inform you if the selected browser supports it.

Google Project: Google Sky

Google Project: Google Sky

Google Sky

Google Sky is a feature launched by Google which is just like Google Earth, where one can view outer space or the outline of the sky. The user can view collaborated satellite images taken by NASA satellites and the Hubble Telescope. Like Google Earth, this is an augmented reality application and is now available on Android too.

How Does Google Sky Work?

With this application, the user can have a look at the vast outer space from anywhere on Earth. While in Google Earth, one can switch to Sky Mode with the help of just one click of the mouse. An accurate look of the outer space has been put together by NASA where users can zoom in and fly around just like in Google Earth.

Broadening Your Vision of Space

From your Desktop, you can access Google Sky by clicking on the planet button placed on the top in the Google Earth application window in the desktop version of it. Google Mars and Google Moon can also be viewed through this. Constellations and other heavenly bodies can be searched just by typing in the key words in the search box, similar to how one can find addresses in Google Maps or Earth.

Just like Earth, Google Sky also works in layers. You can find and highlight constellations, galaxies, nebulae, stars, etc. and get various information on them such as their location or history. You may even get information from links to NASA’s database. The Backyard Astronomy layer in Google Sky gives references of three astrological catalogs that contain in-depth and vast detail on more famous and familiar space objects. The Hubble Showcase is another layer that makes available images taken from the Hubble Space telescope accompanied with detailed information about the objects captured in those images.

 Google Sky

The Moon in Motion and Planets in Motion layers are very fascinating features that allow you see the motion paths of the moon and the planets across the sky from a particular location on Earth.To provide accurate information on the same, pictures were taken by NASA once every hour for the span of three months. After entering details such as the span of time, with just a click you can see the moon or the planets move. On clicking on the moon itself, you can get its exact information of its location, its phase or its brightness in the sky at a given date and time. On clicking on the planets, you can get details about their size or distance from Earth.

Also available on Google Sky are two tours of outer space that are very interesting. The User’s Guide to the Galaxy gives a tour of a number of galaxies that are well known. Another tour known as the Life of a Star gives a run through of a lifespan of a typical star, right from its birth to death. Factual details are also available on what happens to each star and what is its significance in the cosmic universe.

This user-friendly application enables one to take a peek into the fascinating outer space while sitting in the comforts of your home. Thanks to Google Sky, with a simple click you can now make a virtual travel to any part of the vast universe, even to a galaxy far far away.

Google Ingress Offers New Creative Outlets

Google Ingress Offers New Creative Outlets

What is Ingress?

Ingress is a mobile game based on location and has an augmented-reality interface developed by a company called Niantic which is a spin-off company from Google. It is story-driven in which one has to get out of the house to play this game as it takes place in the real world. For this, GPS is required to move around in the real world, that is, to move about in your area or community.

There are different “portals” or places where the gaming activity is focused and these are the points where various people come together. Usually these portals are placed at the nearby museum, sculpture, historic landmark, park, public park and other interesting places.

On arrival at this portal, they have to be explored for equipment, link them or capture them for your own team or free them from the opponent team. All these activities help the player earn points and achievements which are required to level up and access better equipment in the game.

Google Ingress

Ingress is not a newly introduced game and has been around for quite some time. Initially players needed an invite to play the game but in the past year, it has been made available for all, expanding its availability from exclusively Android users to Android and iPhone and since then has gained many more users.

Discovering New Places in Ingress

Ingress encourages the user to get out in their community and explore not only the places around but also new places. The user has to physically present at a portal which is located in the real world, following the real time direction given in the game using GPS. It’s more like following the directions given in Google maps to reach your destination, the difference being this is a game linking the virtual world with the realistic surroundings. One is compelled to go out and about exploring new places while playing the game, resulting in the player to visit a museum, trying out a new restaurant or simply going for a walk in a beautiful park that was there nearby all along.

Making New Friends & Acquaintances

Ingress not only helps you explore places while playing the game but also gets you acquainted with other players. While looking for portals, one ends up meeting other such players at a particular place. Players help each other in crossing difficult levels and also provide tips on how to level up faster. Teams are also formed and they collectively explore places, strategize and overcome obstacles. The community of players is fairly large with each Ingress player playing the game at their own pace, some play it aggressively while some play it casually as and when they find the time.

There are also live events, which allow hundreds of players to take part on a local and even global scale. It’s a great platform to meet players from all walks of life and visit new and fun places. But at the same time, one must maintain caution, keeping in mind that at the end of the day, this just a game and a certain level of separation from the virtual world should be kept.

Windows 10 Tips and Tricks: The Best Hidden Features

Windows 10  Tips and Tricks: The Best Hidden Features

Windows 10 Tips and Tricks

In Windows 10 are some hidden features, of which you may have not heard anything yet. However, these features are often very helpful, which is why we will introduce you to the best hidden features through Windows 10 tips and tricks

Call up a new start menu in Windows 10

Finally, a start menu is again on board: With this Windows 10 tips and tricks we are announcing that the Windows 10 users call it by clicking on the start button or by pressing the Windows button. Another way that is largely unknown: Press Ctrl and Escape at the same time.

Expand the Start menu

Similar to the Windows 10 predecessors, it is easy to customize the Start menu. To add a program, a file, or a folder, right-click on it, and select Attach to “Start”. If you search for an object in the Windows 10 start menu and right-click on the hit, the same context menu entry appears for attaching.

Try out Edge in Windows 10

Microsoft integrates Internet Explorer, another Windows-based: Edge. It is visually slim and fast. To try out the innovative on-board device, click on the IE-like blue icon or on the corresponding Start menu tile. Alternatively, type Edge in the Start menu search box. There are not many setting options. In addition to calling websites, it is a good idea to perform a tempo test on pages such as Peacekeeper: the higher the score is, the faster you are on the web.

Flexible drag-and-drop in the Start menu

You want to convert a list entry from the Start menu to a tile that appears to the right of the menu? Click on the desired entry on the left and drag it to the right to the right with the mouse button pressed. For freshly installed programs, this is recommended: they appear temporarily under Recently Added, otherwise (at least if the Anniversary Update is missing) nowhere in the Start menu. Because, as with Windows 8.1, applications have no authority to place themselves in the Start menu as tiles.

Remove Internet Explorer

Through our Windows 10 tips and tricks announce, that the IE is abolished,( is not true): the program is still exists in Windows 10. The new default browser is Edge. Anyone who wants to get rid of the little improved Internet Explorer will disable it. The required window appears when you press the Windows key and R, and then type the command optionalfeatures and click OK. After removing the check mark in front of the browser entry, mouse clicks are still visible, click Yes, OK and Restart Now.

Start menu programs easier to start

A practical function, which is probably hardly noticed: Invoking programs by Windows 10 start menu also works by mouse wheel. Move the mouse pointer over one of the tiles on the right, and then press the mouse wheel to open the selected object. This works with programs and apps as well as with files and folders.

Drag apps from the Start menu to the desktop

Starting installed apps via desktop, Windows 8 succeeded only with tricks. They are invalid: In Windows 10, if you drag a Start menu app to the desktop with the mouse button pressed, a new icon appears. You can use this function to double-click.

Install apps from the Start menu in Windows 10

For the first time, the Windows Start menu will find applications and web content. For example, if you enter finances in the search function, the system will then offer you “Postbank Financial Assistant” or “MSN Finances” to download. Clicking on such an entry will open the Store app that will run the installation

Start menu without tiles

If you prefer the plain look of Windows XP or 7, create a start menu: To do this, click on all app icons with the right mouse button and choose from “Start”. The empty space remains unused for non-current Windows 10; To shrink the software menu as needed, click the right margin and move it to the left with the left mouse button held down.

If the Anniversary Update is installed, dragging the mouse pointer is no longer required. On the other hand, what is more, the start menu is a little smaller from top to bottom.

PC or Internet

The system shows you apart from hard disk files and folders content from the Internet. To view only local objects, click on one of the icons below after entering a search term. The right-hand character picks up the Bing web service. To confirm your appearance, press Enter.

Windows 10 Language assistant Cortana

Through our Windows 10 tips and tricks we announce here that it has a comparable feature has been already in Vista in the operating system, as smart as in Windows 10, but the function has never been. Cortana is to help plan appointments, retrieve the weather forecast and bing searches. The function usually initiates internet searches in the case of hearing problems. To use, click into the Taskleist search box and log in with a Microsoft account. They call Cortana by clicking on the search field, formulate your request and see if Cortana can help.

The Cortana Intelligence is best developed with a USB microphone or headset. Computing tasks that you tap into the start menu are processed by the digital lady without voice input

Adjust the size of the start menu

How big should the Start menu be? The user has the choice of whether the software menu appears in full-screen mode or much more compact. By means of our Windows 10 tips and tricks we guide you to set the setting, right-click the desktop, and then select Customize> Start, and then click to select the Start menu in the Full Screen mode. Moving the mouse pointer to the upper and right sides of the menu turns it into an arrow.

Split the start menu into categories

There are so many icons placed in the right-hand start menu area. You can get a little more transparency by creating categories. To create headlines for tile icons, first open the Start menu. Match thematically matching symbols. Then double-click the free space above a program group. You then enter a heading and confirm with Enter. You want to change an existing category name? To do this, press the Delete key, type the new text and press Enter
