Goodenough Inventor of Lithium-Ion Battery Reveals Fast Charging, Noncombustible Batteries

King of Battery for almost four decades John Goodenough, Unleashes a new technology, first ever all-solid-state-battery cells that could lead to safer, faster-charging, longer-lasting rechargeable batteries. With this breakthrough in the world of advanced batteries the skeptical world is finding a hard time to believe if this could drain the market of current lithium-ion batteries. Researchers demonstrated the new battery they invented have at least three times as much energy density as today’s lithium-ion batteries.

A team of engineers led by 94-year-old John Goodenough, professor in the Cockrell School of Engineering at The University of Texas at Austin and co-inventor of the lithium-ion battery, has developed the first all-solid-state battery cells that could lead to safer, faster-charging, longer-lasting rechargeable batteries for handheld mobile devices, electric cars and stationary energy storage.
--UTNEWS
John Goodenought says, Cost, safety, energy density, rates of charge and discharge and cycle life are critical for battery-driven cars to be more widely adopted. We believe our discovery solves many of the problems that are inherent in today’s batteries.

People would find it as a bluff if any random person had claimed the invention of all-solid-state-battery. Goodenough being the pioneer and father of Lithium-ion battery, after this invention, people are saying that this could revolutionize the era with the hype of Electric cars and could challenge the automobile industry with the help of this invention.

Flight Mode (Airplane Mode) : On or Off

Traveling by plane has been one medium of faster transportation for few decades. Crossing miles & miles within a minute has made our life really simple. Air Transportation somehow signifies we are quite familiar with the fact of turning our phones into flight mode or airplane mode and turning some of our electronic devices off.

Question may arise why we need to do this stuff especially, during take off and landing. Why electronic device should be turned off during flight? Can the 900$ phone take 90 million dollar jet to the ground and burn it with its own jet fuel, just because

we didn't turn our phone off to the FLIGHT MODE?

Airplane cockpit i.e. the front part of the plane where pilot takes control over the plane is filled of highly sensitive equipment required for navigating, communicating and other requirement for safe flight. All electronic devices have electromagnetic field that can interfere with the radio frequencies. It’s not only the cell phone but there is electromagnetic radiation that emits from every electronic personal devices and interfere with the the plane’s navigation system, communication system. The electronic signal can also interfere with the signals between the plane and radio station during takeoff and landing.



Safety officials worries that the electromagnetic radiation might interfere with this sensitive equipment in the airplane and creates safety issues. Devices like portable DVD found to drift airplane GPS system few degrees (research from few years ago). This thing can be resolved by turning it off.
If you argue with the flight attendant over using cell phone, you could be arrested and taken off the flight. If you intimate the flight attendant, you could be jailed for decades.

Likewise, issue of frequency reuse also happens simultaneously.
The frequency can’t be distributed all over the places with single tower. So the cell phone company establishes tower from place to place to reuse the same frequency. With car driving along and people communicating from office and home, there is a little chance that this frequency will overlap in another area and create problems. 
It wont be hard to make a call when you are on a ground. You just communicate through single frequency with single tower. However during the flight when you are flying 500 miles per hour moving around the signal will reach out in different towers with the same frequency at same time and interfere with the ground base cell phone system. And increases the possibility to interfere with the plane’s equipment.

In America because of the Federal Communication Commission (FCC) one should put their phones with airplane mode on. FCC regulations ban the use of cell phones on planes in order to ‘protect against radio interference to cell phone networks on the ground.”

Present time most of the airplane flight provides on air time. Newer plane technology uses the pico cell which acts like a mini cell tower or base station on board and allows the plane on a flight and tower on the ground to interact normally. Basically, the range of a pico cell is 200m or less which is suitable for the plane on flight. Air France was the first airline to allow the use of cell phone in their planes to mail text make receive call.
“It’s never been proven that a mobile phone signal has interfered with the navigation performance of the aircraft. But just because it’s never happened doesn’t mean it will never happen.”

-A pilot tells Business insider

Graphene Super Capacitor : Future of dash charging


Today’s technology has push the mobile devices far beyond than its limit. We can possibly imagine how smart phones has made our life comfortable and straightforward. With the ratio of developing smart phones their batteries hasn’t been able to be in the point where they should be. Of course there are dash charging but still they are time consuming and not completely developed as they need to be. And still we are adopting the traditional way of charging, using lithium ion and lithium polymer batteries. 


The concept of Graphene Super Capacitor might be the history changer for tomorrow’s world of fast charging. A battery, high energy storage charges slowly and discharges slowly this ability is energy density. Similarly, capacitor , a low energy storage charges rapidly and discharges rapidly which is the power density. Combining the best of both will lead to fast charging and slow discharging. Super capacitors lies between the concept of this two energy storage methods. 

Eesha Khare, a graduate from Lynbrook High School California developed a super capacitor prototype that charges very rapidly and would last longer for more charging cycles. And was runner up at Intel International Science and engineering Fair (2013) bringing out this prototype. Its still prototype in the current state but proved to be work.

Her prototype could be fully charged within time interval of 20-30 seconds and hold the charge for longer like on other similar devices. It lasts for 10,000 cycles compared to batteries in current world 1000 cycles. Much greater achievement in field of energy storage.

Nano scale and mass scale fabrication hasn’t been practically possible on today’s world. Gradually, scaling up this prototype will lead to powering phones and electric cars. Like increasing the technology the maH of batteries will also certainly increase in the future. 

Imagine plugging your phone in, charging it for about 20 second and of that charge it will work one day or more.

7 Most Useful Quick Android Tips For Beginners

7 Most Useful Quick Android Tips For Beginners

We’ve been consistently coming up with various guides and tutorials for Android. If you haven’t still checked our beginner guide to basic Android settings, then you want to check them out because you might be missing 10 very useful tips to get most out of your Android device.
Moving on, here are seven most useful quick Android tips. These tips are definitely helpful to increase your productivity level, which includes disabling vibration during phone calls, taking screenshots, settings default dialer, optimizing phone screen, viewing saved wireless network password, hiding files and folders, and adjusting brightness using status bar.

TIP 1: HOW TO DISABLE VIBRATION DURING CALLS ON ANDROID

Whenever you get calls on your Android, by default the device rings along with vibration. This feature during calls is useful if you’re in a noisy place where its difficult to hear the ringtone; in that case the vibration might make you aware of incoming call.
But, vibration during calls is not always useful, so some of you might want to disable it. Disabling vibration might also save you some percentage of your battery charge.
On your Android device,
  • Go to Settings
  • Open Sounds
  • Scroll down to the Vibrate section and turn on/off Also vibrate for calls option
In this way you can now select your own preference during incoming call, either ring only or both ring & vibrate.

TIP 2: HOW TO TAKE A SCREENSHOT ON ANDROID

Do you want to share your score after getting a new high-score in a game, share portion of webpages, or share anything that’s on your Android screen? Whatever might be the reasons, you can simply take a screenshot to capture your Android screen and share it online or do whatever you’d want.
Taking a Screenshot on Android
  • Hold down Power button + Volume down buttons at the same time
  • Continue holding the buttons until you hear a click or a screenshot sound
To view screenshot
  • Visit Gallery app
  • You’ll find your screenshot image under Screenshots album

TIP 3: HOW TO SET THE DEFAULT DIALER IN ANDROID

Making an app default (selecting “always” options) means that the system won’t display any prompt to select an app the next time. One of my friend recently downloaded a dialer app from Google Play, and made that particular downloaded app the default dialer app to make calls. Now he wanted to revert back to the Android default dialer.
Well, there is an easy way to revert to the default one.
Visit settings > Applications > Manage Applications. 
Select the “downloaded” among the tab menu, to view the list of applications which you’ve downloaded. From the list select the dialer app which you’ve downloaded. Within the dialer app info page, scroll down and press the “clear defaults” button.
That’s it, now open the dialer, and this time you’ll be prompted to select an app to open the dialer.

TIP 4: HOW TO OPTIMIZE PHONE SCREEN IN CYANOGENMOD

LiveDisplay, one of the cool feature which CyanogenMod has added to their nightlies and I personally first came across this feature on OnePlus phones running CyanogenMod 12.1. LiveDisplay optimizes the phone screen based on time, providing various options including color temperature, brightness & saturations, enhance colors, screen color.
Viewing LiveDisplay Settings in CyanogenMod
  • Visit Settings
  • Select Display & Lights
  • Tap on LiveDisplay
Now let’s go through the available options which you can manipulate to optimize your phone screen.
Activating Night Mode in CyanogenMod
Visit Settings > Display & Lights > LiveDisplay, and tap on Display mode to select Night which automatically activates Night mode on your CyanogenMod phone.
Similarly, you can activate the Outdoor mode which optimizes the settings so that you can effectively use your phone while you’re outdoor, under bright sun.
Activating Automatic Screen Optimization in CyanogenMod
  • Visit Settings
  • Select Display & Lights
  • Tap on LiveDisplay
  • And select Automatic from the list of modes
Instead of selecting modes (day, night, outdoor), some might consider allowing the system itself to auto manage and optimize. No matter, which time you use your phone, the system automatically adjusts its settings.
Adjusting Screen Color of Your Phone Screen
While you’re inside LiveDisplay settings, visit Screen color option below Calibration. Here you can adjust the Hue, Saturation, Contrast and Intensity of the screen.
You have predefined settings: Standard & Vivid – available for adjusting Screen color.
If you want to manually adjust the settings select Custom, and tap the gear icon. Now slide the sliders as per your preference and once you’re done, tap SAVE button to apply the changes.

TIP 5: HOW TO VIEW SAVED WIFI PASSWORD ON ANDROID DEVICES

Sometimes you might forget the password of the Wireless networks (WiFi) which you’ve previously connected to. Once you connect to a network, your Android system automatically saves the network’s details, so that the next time you connect to the same network you won’t have to enter password again.
Logging into the router and viewing the wireless settings might be the first option, only if you’ve access to the router. What if its a public, or other networks (office/company) where you don’t have direct access to the router?  Well, in that case there’s a workaround that lets you view saved WiFi password on your Android device.
Disclaimer: Make sure that your Android device is already rooted.
  • Open Terminal Emulator on your Android device
  • Type su in the terminal to gain superuser access
  • Use cat command to view the content of /data/misc/wifi/WPA_supplicant.conf file.
cat /data/misc/wifi/WPA_supplicant.conf 
WPA_supplicant.conf files stores the details of networks which you’ve connected to.

TIP 6: HOW TO HIDE FILES/FOLDERS IN YOUR ANDROID DEVICE

Whenever we are forced to hang out with kids and relatives, it’s usual case that your cousins are always curious to play games and view gallery on your mobile and the hard part is you can’t say “NO”. In fact, someone may sneak your phone without permission and take valuable or private data that you don’t want to share.
Here’s the quick solution for your android device to hide any file without using any third party app. The hidden file will not be view-able on your gallery, multimedia players, office editors, etc. It’s easy and only takes a second to hide your data from anyone until and unless the person knows about this trick.
  • Unlock your device, and open File Manager
  • Click the setting option > Show Hidden files
  • Now go the desired file/folder that you want to hide.
  • Just rename the file with (.) dot before the filename and save it. For example, “.sandy” or “.thequickblog”
  • And the file will be hidden. You can mark/unmark the Show hidden file option whenever you desire.
Hiding the Contents Without Renaming the Folder
  • To do so you can create a file by naming it as “.nomedia” inside the folder that you want to hide. It’s content on the Gallery will be hidden without renaming the folder.
Note: It works on most of the android devices but for Sony Xperia series, this workaround works only if it is a Premium app. In free version you can’t access this feature. You better download a file manager from google play store.
For Samsung devices, the name of default file manager is Files.

TIP 7: HOW TO ADJUST BRIGHTNESS BY SLIDING ACROSS STATUS BAR IN CYANOGENMOD

Ability to adjust brightness of your Android device screen by sliding across status bar is one of the cool feature which CyanogenMod has brought to their latest ROMs. In most of the android devices, brightness can be adjusted using the brightness level bar, but CyanogenMod users can quickly adjust the screen brightness of their CM powered Android device by sliding across the status bar.
Activating “Slide Status Bar to Adjust Brightness” Feature
  • Visit Settings
  • Select Status Bar under personal heading
  • Tap on Brightness control
Adjusting Brightness from Status Bar
Place your finger over the status bar and slide from left to right to increase the brightness and similarly slide for right to left to decrease. You can see the changes in the brightness level of your device in realtime, while you slide your finger across the status bar.

CONCLUSION

I hope these android tips were in anyway helpful to you.
Android is the most customizable phone out there, there are many workarounds which you can perform with your Android device to get most out of it. So for now, I am signing off from this post, promising you guys that I will be back with more other Android tips and guides.

THE EVOLUTION OF 5G

G. Marconi, an Italian inventor, unlocks the path of recent day wireless communications by communicating the letter ‘S’ along a distance of 3 Km in the form of three dot Morse code with the help of electromagnetic waves. After this inception, wireless communications have become an important part of present day society. Since satellite communication, television and radio transmission has advanced to pervasive mobile telephone, wireless communications has transformed the style in which society runs. The evolution of wireless begins here and is shown in Fig. 1. It shows the evolving generations of wireless technologies in terms of data rate, mobility, coverage and spectral efficiency. As the wireless technologies are growing, the data rate, mobility, coverage and spectral efficiency increases. It also shows that the 1G and 2G technologies use circuit switching while 2.5G and 3G uses both circuit and packet switching and the next generations from 3.5G to now i.e. 5G are using packet switching. Along with these factors, it also differentiate between licensed spectrum and unlicensed spectrum. All the evolving generations use the licensed spectrum while the WiFi, Bluetooth and WiMAX are using the unlicensed spectrum. An overview about the evolving wireless technologies is below:



From Generation 1G to 2G and from 3G to 4G, this world of telecommunication has seen a number of improvements along with improved performance with every single passing day. This fast revolution in mobile computing changes our day to day life that is way we work, use, interact, learn, implement etc. Until now we have achieved 4G technology and yes the smartphones manufactured now a days are a featured example of this generation. The underdeveloped countries such as Nepal itself had not been able to use of this generation unlike other countries where the research and innovation towards the next generation has already been on its way. All we can say is that 4G is a significant achievement for the further development of the 5G technology.

Now, let’s dig up what 5G is all about. The 5G aims to achieve the vision of essentially unlimited access to information and sharing of data anywhere and anytime for anyone and anything by providing affordable broadband wireless connectivity at very high speed (higher than 1 Gbps, 4G offers the wireless internet connectivity of about 1Gbps). The in use EDGE technology in 3G devices and now, Wi-fi using LTE in 4G will ultimately be developed into WWWW( World Wide Wireless Web ) to provide global sharing in a large scale through a common connected network from different devices also called ubiquitous (global) computing which means the user can simultaneously be connected to several wireless access technologies (2G, 3G, 4G or 5G mobile networks, Wi-Fi, PAN ) and seamlessly move between them and result in multiple concurrent data transfer. It’s not just about super-fast internet connection and capacity, it’s about not compromising the needs of thousands of people. Suppose if you are in a Stadium along with other 30,000 people who are accessing mobile data to upload a photo in a social media then by 4G it’s a great deal but 5G uses innovative technology that can allocate each users with their own antennas. So, that makes 5G almost 10 times faster than 4G.



Additionally, it focuses on (Voice over IP) VOIP enabled devices that user will experience a high level of call volume and data transmission. It will give you the concept of intelligent Internet phone where the mobile can prefer the finest connections. It will support IPv6 where a visiting care-of mobile IP address is assigned according to location and the connected network. 5G will also provide wireless connectivity for a wide range of new applications and use cases, including wearable devices, smart homes, traffic safety/control, and critical infrastructure and industry applications, as well as for very-high-speed media delivery, documentation, supporting electronic transactions (e-Payments, e-transactions), and multimedia newspapers, also to watch T.V programs with the clarity as to that of an HD T.V. It is expected that the initial Internet philosophy of keeping the network as simple as possible, and giving more functionalities to the end nodes also using 5G with cloud computing and nanotechnology in real wireless world with no more limitation to access and zone issues.



Evolution beyond mobile internet from analog through to LTE (Long Term Evolution), each generation of mobile technology has been motivated by the need to meet a requirement identified between that technology and its predecessor, the next generation must be about the advancements in all existing mobile technology so smart that it can ultimately result in artificial intelligence. By 2020, 3D movies and games, real-time streaming of ultra HD 2K content and remote medical service will be common on a smartphone resulting in need of 5G networks.
