Apple is Finally Going to Test Self-Driving Cars

Apple is Finally Going to Test Self-Driving  Cars

The world has all the ears on the technology news and what if the news is from the greatest smart phone maker in the world- Apple about the self-driving cars. Well, it surely catches the attention of all the netizens as well as those who are cars frenzy. Apple was given a nod to go with their project of self-driving cars after months of speculation. This has been a great chance for them to showcase their potential in automotive technology. Like Google, they were given three Lexus SUVs for the autonomous cars testing. After obtaining the green signal from the California’s DMV. Apple is now pushing its limits to make a mark in the field of automotive industry.

THE TEST

Like the other cars or companies, Apple will also have its human drivers behind the wheels once they hit the roads of California. Hover, Apple has to compete with the other automobile giants like the BMW, Ford, Honda and many more. There were speculations about the project. There were often rumour about the technology news with regards to driving cars from Apple. Some said that the Apple was going to name the project like “Apple car”, “the iCar”, “Project Titan”

 

THE RUMOURS

Well, some reports came out that the company would be manufacturing driving vehicles while some were focused to spread that the tech giant company was building software for the automobile industry. The software could be used in multipurpose in automobiles. The technology news that buzzed and caught everyone’s ears was that Apple was building cars which were driven by electric or battery much like the Tesla cars. Well, it would certainly put Musk in thoughts. In the late 2015, when Apple hired the automotive engineers, there was a fresh wave of rumour.

 

THE CHANGE

There was a change in the assigned task for which the engineers were hired. They were mainly asked to focus on the software part for the self-driving cars. Whatever Apple does will be the attention for all the people in the world. Now Apple is just waiting for the right time to build the world’s first innovative self-driving cars. The report states that Apple is the 30th company to bag the deal of self-driving cars.  This is indeed a big achievement for the tech giant company who are leaders in the smart phones. This is a great idea to get a kick start in the field of automotive industry. Apple will slowly get the permits in California for all the necessary things required in self-driving.

 

THE SPECULATIONS

Even after getting the permit from the concerned authorities, there is still a speculation on what actually Apple is working. There has been no confirmed news from the company. It is however to be seen to what dimension the work gets into. The more technology they put into will make the cars more accident free and reduce the chance of any casualties in the near future. So, we just need to have patience and wait for the confirmed news to break out.

Beyond Graphene: Advances Make Reduced Graphene Oxide Electronics Feasible

Beyond Graphene: Advances Make Reduced Graphene Oxide Electronics Feasible

Conversion of Reduced Graphene Oxide Opens Up a New World for Technological Advances

Graphene is an allotrope of carbon which forms a thin layer of carbon atoms bonded together in a hexagonal honeycomb. Isolated in 2004, it has remarkable physical properties that can be applied to a number of things.

The news of its invention created a frenzy in the world of science as Graphene was the thinnest material known which is 150 times stronger than steel and can stretch to 120% of its length. Around the world, research institutions have been trying to develop ways to revolutionize the production of  sheets.

Technology has made this possible by the reduction of Graphene oxide into rGO or reduced Graphene oxide.  This is an extremely vital process which impacts the quality of the rGO produced. It can be achieved by chemical, thermal or electrochemical processes.

It is no news that scientists had already found a number of methods to rGO in the past. This could be done through a number of technological means such as:

  • Treating Graphene oxide with hydrazine hydrate.
  • Exposing it to hydrogen plasma or a strong pulse light.
  • Directly heating Graphene oxide or heating it in distilled water at varying degrees.
  • Combining it with an expansion-reduction agent like urea.
  • Linear sweep voltammetry.

The major flaw of this technology is that chemical reduction has resulted in poor yields in terms of surface area and electronic conductibility. Thermal reduction structurally damages Graphene platelets with pressure build-up and release of carbon dioxide. According to recent news, electrochemical Graphene reduction is the best method to produce high quality rGO, which is almost similar to pristine Graphene.

According to Jay Narayan, it is extremely conductive but it is not a semiconductor. That is why he created rGO. Researchers in his lab, Narayan and AnaghBhaumikwere able to convert p-type or positively charged rGO into n-type or negatively charged rGO and create a layered material.

This material can be used to develop rGO based transistors that can be used in electronic devices.  They achieved this by implementing a completely new kind of technology where they combined rGO into the entirety of wafers made of silicon or sapphire.

This successful wafer-scale integration was done through a pulsed laser deposition technique.  The researchers used laser to confuse chemical groups and move electrons across groups, throughout the wafer. This effectively converted positively charged rGO to negatively charged rGO in a process of pulsed laser annealing using a nanosecond ArF excimer laser.

This wafer scale integration is done at regular room temperature and pressure and takes about 1/5th of a microsecond for completion. It results in a wafer with negatively charged rGO layered on the surface and positively charged rGO layered underneath.

The p-n intersection where the p-type and the n-type meet is extremely important for transistor applications. News of this scientific breakthrough has taken the world of researchers by storm as it has opened up a new frontier for further extensive research in Graphene-based functionalized 2D materials.

Samsung New Artificial Intelligence Assistant Bixby will take on Siri and Alexa

Samsung New Artificial Intelligence Assistant Bixby will take on Siri and Alexa

Samsung Bixby has all the big guns! Siri better watch out!

Yes, Samsung Bixby has all the big guns! Anyone who watches The Big Bang Theory would perhaps recall the episode in which Penny has a great idea for an app: you take a picture of a shoe and this app searches it for you. With the market flooding with different voice assistants, you would think, this had already been done! But apparently not! Even though technology news keeps updating us consumers about every little thing that happens, there has been no news for this!
Until now!After the very public and very embarrassing debacle with their flagship device, Note 7, Samsung has been thrust quite voluntarily under the public eye once more for its new flagship device the S8 which they are launching with their new player: Bixby.

Sure you know Apple’s Siri, and Amazon’s Alexa and Microsoft’ Cortana, which are basically all AI voice assistants. In fact when Apple released the iphone7, the marketing was primarily strategized around Siri, whose performance, the company claimed has been upped a few notches. And if technology news is anything to go by, they were not wrong.

So how does Bixby endeavour to compete with its existing competition? Before getting into that, it might be prudent to remember that all these apps primarily run via voice commands, so once you change over to any other form of communication, perhaps a touch command, and your task would either be left in medias res, or be begun entirely anew! Frustrating as it may sound, no substantial improvement has been made in this area. Until Bixby that is!

Samsung claims that Bixby unlike other voice-operated assistants, can be used on multiple platforms. It markets the S8 as a completely new way to use your phone. In addition, you can do it via touch; you can use texts or the simplest: your voice, being integrated throughout the device. Of course if technology news is anything to go by, Samsung wants Bixby to perform so unparalleled in its capability so that it can transcend from just a phone interface and can be integrated in all phases of your life, even household appliances.

If you are lost and find it problematic to navigate Google maps, then perhaps Bixby is going to be your best friend because if Samsung’s claims are anything to go by, all you have to do is open the camera and take a photo and the rest of the information would be provided to you by your phone.

Once again if technology news and Samsung’s claims are anything to go by, Bixby is apparently well endowed to follow commands like “show me a picture of Billy. Text it to mom”. If this is to be believed, then there is nothing on the market close to it now and apple must sit up and take notice.

Samsung however does tell you that Bixby operates based on your needs which it picks up from the way your phone has been customised to the apps which are used most frequently. And of course unlike any other assistant, it is also your daily planner and fitness tracker, just a bit better than its competitors.

Supercritical Carbon Dioxide: The Tough Coating for Silicon

Supercritical Carbon Dioxide: The Tough Coating for Silicon

We are living in a society, where the science and technology have taken the center stage of all possible developments and in almost every day, we are witnessing some new concepts or developments in the arena of the science and technology that helps our life and circumstances to be more composed and ease. Very recently some scientists and engineers have developed a method that can be of great help for materials, especially Supercritical carbon dioxide, for various applications, ranging from batteries to the most elegant biosensors1. Some of the relevant issues, related to these developments are as follows:

  • Sreenivasa Reddy Puniredd and his colleagues of an “A” Star Material Research and Engineering institute have developed a simple and new way that can be helpful to deliver the essential protective molecules by using the Supercritical carbon dioxide, popularly known as scCO2.
  • In this process, the normal Carbon Dioxide is being converted to the Supercritical carbon dioxide under extremely high pressure, when this becomes the free-flowing liquid, which is chemically inexpensive, inert and comparatively more environment-friendly than other traditional solvents.
  • The research team used the Supercritical carbon dioxide, scCO2, in carrying molecules, known as alkyl thiols, which is having a long chain of carbons and an atom of Sulfur at one of the end. Here Sulfur forms the stable bond with the silicon, while water-repelling chains of carbons make the tightly-packed skin on the surface of the silicon.
  • This is a simple green method, where the silicon forms the oxide layer on the surface at the time of exposure to moisture and air, which have the potential to detract from its own electronic properties. It can be noted that the adding of the molecular “skin” to the silicon is providing a physical barrier to prevent oxidation, but by forming these monolayers could have been tricky and require longer processing time, as well as, the inert atmosphere or demanding the uses of the harmful solvents of organic nature.
  • In applying the coating, researchers had used alkyl thiols that contain seven to eighteen atoms that could coat germanium, silicon and the silicon nanowires. Each of the procedures took almost few hours and able to produce monolayers of 1.6 nanometers to 2.3 nanometers of thickness, which are able to resist wear and in repelling water to a great extent. The most notable and greatest effect had been seen for the longest chains of alkyl thiols.
  • These monolayers also having the potential of protecting the surface, more than fifty days, from oxygen. These are prepared by using the conventional solvents, had been typically stable for the shorter period of time, even less than one week. It is stated that the increase in the stability was an expected issue, but such a longer stability was a real surprise for the research team.
  • Ths Supercritical carbon dioxide technology can be used in the modification of a different variety of inorganic surface and it may be worth mentioning that this technology is able to enhance the stability and enhancement of the respective film, apart from being scalable.
