Samsung Unveils Tech That Can Double Lithium-Ion Battery Capacity

Currently more than 80 per cent mobile users are using smartphones in all over the world and they are pretty satisfy and happy with the features and operations of device. But still the major concern of smartphone owners is the battery life of smartphones. If we believed on the latest report which was published last week in a journal, so there is way to double the capacity of lithium-ion batteries.

Report published by the researchers of Samsung claims that their new technology will enable the batteries to provide 1.5 to 1.8 time’s higher capacity in comparison of commercial lithium-ion batteries, which we are using in present. In the process to enhance the battery life, Samsung has come up with brand new coating technique only for battery cathodes which promise to overcome from the limitations of lithium ion batteries. According to published report in Nature Communications, this new battery technology will employ the use of graphene on the surface of silicon and it will offer the volume expansion, which will play vital role in the extended battery life.

The published report explains, “Here we are reporting the growth of grapheme directly over the silicon nano-particles with or without silicon carbide formation as the layers of graphene anchored onto the surface of silicon to accommodate the volume expansion for silicon with the help of a sliding process between the adjacent layers of graphene. When it paired with a lithium cobalt oxide cathode (commercial), so the coating of silicon carbide free graphene allow the cell to reach on the maximum volumetric energy densities, which is 972 and 700 Wh l-1 respectively however; the final result is 1.8 to 1.5 times higher capacity in comparison of commercial lithium-ion batteries, which we are using in present.

According to the tech experts and researchers the new technology of lithium-ion batteries will deliver the extended battery life however; soon it will be available as commercially viable option. The observation of researchers suggests that layered structure of graphene is two-dimensional and its integration with silicon and silicon carbide-free is able to serve as a prototype when it comes to advancing silicon anodes as commercially viable technology”.

Samsung, a consumer electronics giant located in South Korean acknowledge that this new technology will make the batteries less competitive in the cycle life due and volumetric energy density because of additional discharge cycles, however; researchers are still working hard to improve the effectiveness of these new batteries and it’s fair to say that currently we shouldn’t expect double the battery life in upcoming Galaxy Note 5 and Galaxy S7. As per experts, it will help the Samsung to get the desired boost in smartphones and laptop segments as users prefer to get more battery life for their devices.

Apart from that last year, researchers from US have developed an advanced or smart lithium-ion battery, which warn or alert the users from potential overheating as well as fire. This technology was designed for the traditional lithium-ion batteries and currently billions of laptops, tablets, cell phones and other electronic devices are using these technologies along with growing number of airplanes and cars.

Honda New Jazz – Autoportal India brings you all the Details

Honda, the Japanese carmaker, has offered the Indian car lovers some of the finest cars in the world. Although the Indians warmly welcomed all Honda cars, the premium hatchback Jazz failed to excite the buyers. Eventually, Honda had to withdraw the car from the market. However, the company has decided to bring back the hatch now. According to the reports, it is expected to hit the Indian roads on 8 July 2015.

In its second innings, the Jazz is likely to be more competitively priced and positioned. According to web portals like Autoportal, Honda Jazz price is at INR 5.5 lakh and upwards. It is an indication that Honda is not leaving anything to chance as far as the second innings of this premium hatch is concerned. Another area of concern would positioning it in the market. As pricing and positioning were two major reasons for the failure of the first edition, Honda would now look to address them better. If what we have heard and seen until now, it looks like they have the things under control as far as the new Jazz is concerned. Even so, it would have to face a tough competition to claim its place in the market.

It is rumored that the price of the new Jazz would be between INR 5.5 lakh and 7.1 lakh. Honda is able to offer such competitive prices because of the localization that has happened in the new Jazz. It is said that the new car is carrying up to 90% localization, which has resulted in the company being able to offer the car at lower prices.

It is also said that the Jazz, like its sibling Honda City, will come in five variants - E, S, SV, V and VX. The tired and tested 1.2-litre i-VTEC petrol engine, which is currently on duty on the cars like Amaze and Brio, will also power the Jazz. This engine can generate a maximum power of 90 bhp along with a peak torque of 110 Nm. The diesel variants will have a 1.5-litre i-DTEC diesel unit, which is capable of generating 100 PS of power and 200Nm torque.

The petrol variants will get either a 5-speed manual or a CVT with paddle shifters. They are expected to offer a mileage of 19 kmpl. The diesel variants will be equipped with a 6-speed manual transmission. The mileage expected is 21.3 kmpl.

The safety and comfort features would include a 15.7cm touch screen AVN system, adjustable rear headrests, automatic AC with touch controls, paddle shifts (CVT only) , steering wheel mounted hands-free telephone control, fabric upholstery ,electric folding OVRMs, multi-view rear parking camera, ABS with EBD and Driver and passenger airbags, to list a few.

How to Create an Attractive PowerPoint Slide

When you’re responsible for creating an attractive PowerPoint slide design, there are several ways you can make your slides look more inviting. It’s important to keep your attendees engaged throughout your entire meeting; here are some simple ways you can create a powerful and effective presentation.

Prioritize and Keep it Simple

Whether you choose to work with horizontal or landscape slides, remember that the main star of your show is always your audience. Don’t make the mistake of spending all of your time developing your powerpoint slide design; create slides with your attendees in mind instead. You do not have to fill in all of the negative spaces in order to keep your audience captivated. Sometimes less clutter is better.

Creating Great Slides

Create slides that accommodate your speaking points, rather than creating slides that leave little room for you to speak. Your text should be concise and to the point, and if you can use images instead of bullets, chances are your topics will be much easier to remember. Instead of filling in your PowerPoint presentation with too much text, draft a separate handout that you can pass out to your attendees after they’ve seen your presentation.

How to Use Charts

Whenever you’re working with percentages, it’s best to work with pie charts and to limit slices to around four or five color-coded graphics. When you’re comparing different qualities, horizontal bars tend to work best, and if you’re attempting to demonstrate changes that have occurred over several years, vertical bar charts might be your best bet.

Colors Enhance Visibility

Implement color schemes whenever possible to evoke feelings. Using appropriate color choices can help motivate your audience. Cool colors are best used for backgrounds, while warm colors typically work best for images that are in the foreground of the slide. If you’re presentation will take place in a brightly-lit room, however, it might be more effective to choose a solid white background instead of a colored one.

Your presentation can be a success, as long as you remember that it’s more important for you to engage your audience rather than solely relying on your PowerPoint presentation.

Lexus has designed a Working 'Impossible' Hoverboard

As there is a havoc development in the communication system, there are lots of changes that have occurred in last few decades in the transportation, personal and public, systems. Hoverboard is such a most modern personal transport solution, which is getting popularity among the young generation. This is such a craze now that it is used in popular film like Back to the Future (in both part II & III) and created interesting impression in the younger folks. But due to confusion of fear among the parents; it has not been marketed so far in commercial manner.

Hoverboard – A Glimpse of Real Thing

The Hoverboard is almost like a skateboard, but there are no wheels underneath like the later and propelled by levitation theory. Many scientists and companies, all over the world, are trying to make the best possible transportation systems by using the levitation theory e.g. “Meglev” rail system but it is not yet commercially run by any entity. The levitation system is nothing but an autonomously fuelled vehicle that runs on the strength of the magnetic power over the ground level, without touching the surface.

Undoubtedly, the Hoverboard is the most modern invention and it is going to be a big success in the personal transportation system. Although a decade ago, it was just like another science fictional issue but now it becomes a reality and already trial runs have been made by Canadian creator Catalin Alexandru Duru and also by Lexus – the famous car brand has developed their own version of Hoverboard and issued a real video of its operation.

Lexus – Its Own Designed Hoverboard

Though there are some instances of “real” Hoverboard videos and news but the authenticity of these claims are yet to be recognized but this time the famous luxury car brand Lexus, has issued a video trailer of their newly developed Hoverboard. It appears from the video clip that it is a genuine product and the company’s brand value cannot be challenged in this issue because the said Hoverboard is realistically run above the ground level.

For last 18 months the company was trying to develop the project in to a reality and only now they are able to prepare the prototype, which has been shown in the aforementioned trailer. While we are talking about levitation; the automatic realization is that the Hoverboard will have a magnet and has to run on a metal track. Lexus has confirmed that they have used liquid nitrogen cooled superconductors and stable magnets, the basic product for getting the levitation.

However, as appears from the trailer that it was run on normal skatepark or bituminous road but actually there was a metal strip or layer underneath the road surface, which is confirmed by Lexus. The company has prepared the most convincing prototype and it is very much real with a gorgeous design and look, which will soon be followed by others.

The “impossible” dream has already been translated in to “reality” and made the history by Lexus.

Brain-to-Text Tech Lets Computers Read Your Thoughts

Technology is continuously evolving and revolutionary in nature. A new revolutionary technology has found fame with its ability to construct thoughts into text in the most accurate manner. This technology showed that a person thought can be easily transcribed on the computer screen with ease and grace. This will be great news for the patients who lack an easier to communicate and express their thoughts in the past.

This is for the first time scientist has made a breakthrough in envision and developing a technology which can transcribe brainwaves into text successfully. This means that the people who are terminally ill or are unable to speak can use the system to ‘talk’ with the help of a computer.

People behind This Revolutionary Technology

This technology is a result of collective research done by a group of talented informatics, neuroscientists and medical researchers at Albany Medical Centre. This team has been able to identify the brainwaves which specifically relates to the speech by using electrocorticographic (ECoG) Technology. This technology was utilized to monitor the frontal and temporal lobes of distinct seven participants who were epileptic. During the research needles were used to record signals directly from the participant’s neurons through an invasive and safe procedure of making incision in the skull.

How The Research Was Conducted? 

In the research the participants were asked to read aloud from the given sample texts. In the same time a machine learning algorithms worked out towards finding the most likely word sequence from the signals produced by the participants and as recorded by the ECoG. With the help of existing speech-to-text tools then worked toward transcribing the continuously spoken speech signals from the brain activity of the participants.

The Findings of This Remarkable Research

The error rates during this research were extremely low at just 25 percent which is a positive sign as it shows the potential for this technology is vast. This finding proves to be a boon for the locked-in and mute patients who don’t have any valuable communication method before. The brain to text tech utilizes the decoding approach which offers an ideal option for developing real-time online application on the desktop computers which can easily read the signals and transcribe the thoughts without the need of a keyboard. Apart from this it can also be valuable for the humans in order to communicate directly with the computer in future without need of any intermediary equipment.

Future Prospects of This Technology

At the moment it seems unlikely that the bran-to-text tech can make it in the computer product segment as there is no viable method. Currently it can be done only by the researchers through cutting into brain and accessing the brain waves. But with further improve and research new ways can be found to bring it in the mainstay for public usage and greater good of humanity. It can be easily ascertained that the future prospects of this remarkable technology is endless.
