Sept 23, 2016: The first case of fire in Samsung Galaxy Note 2 smartphone inside an aircraft in India was reported on Friday, prompting aviation regulator Directorate General of Civil Aviation (DGCA) to summon the company officials and ban the onboard use of this series of devices of the South Korean major.
The case was reported inside an aircraft at the time of landing at Chennai airport on Friday, but the name of the carrier could not be ascertained immediately.
With the latest incident, the DGCA has asked airlines to advise passengers to switch off their Samsung Galaxy Note phones while on-board.
The move also comes two weeks after the watchdog banned the use of Samsung Galaxy Note7 onboard an aircraft following a series of incidents of the smartphone’s battery exploding in various countries. However, this is the first incident of the Samsung device catching fire onboard in India.
Sources said a Samsung Galaxy Note 2 is suspected to have caught fire on an aircraft landing at Chennai airport at 0745 hours on Friday.
The crew had to use fire extinguisher to put off the smoke and following the incident, the DGCAhas called in Samsung officials to meet on September 26, sources added. (IANS)
Aug 03, 2017: Owning a smartphone is one of the essential things for the youths today, not knowing the fact that extreme usage of the mobile phone can cause an irreversible damage to the mental and physical health. Youngsters have involved smartphones in their routine to an extent that they work, play, eat and sleep according to their mobile phones.
Albert Einstein aptly said, “I fear the day that technology will surpass our human interaction. The world will have a generation of idiots.”
There are plethora of negative impacts of cell phones on teenagers and mentioned below are the three effects of smartphones :
1. Possessing a smart phone will prompt your teen to spend all day hanging upon the device, instead of doing anything productive. Teens who spend much of their time with cell phones are more predisposed to stress and fatigue. It can also lead to psychological disorders in some cases.
2. Many teenagers keep their cell phones nearby while sleeping to respond to texts and calls, which leads to sleep disruption and interruption. Improper sleep in return makes the person irritable and weak.
3. Electromagnetic radiation emitted by mobile phones get absorbed in the tissues when we hold the phone for prolonged period of time. The nervous systems of your teens are still developing and thus longer usage of phones may trigger a greater risk of developing brain cancer from cell phones than adults.

The newly developed material enhances response rate by thousand times from existing materials and can store more energy in less space, for applications like mobile handsets, specially new-age smartphones
A team of Indian and French scientists have developed a touch sensitive material that enhances response rate by thousand times from existing materials
The material is made of Quantum Dots (QD) with liquid crystals; QDs are very small semiconductor particles, only several nanometres in size
The team controlled the assembly of quantum particles in liquid crystal matrix for this specific purpose and by changing the concentration of QDs
New Delhi, August 1, 2017: A super touch sensitive material has been developed by a team of Indian and French scientists. This material has the ability to enhance response rate by thousand times from existing materials. A super touch sensitive material has been developed by a team of Indian and French scientists. This material has the ability to enhance response rate by thousand times from existing materials.
The material is made of Quantum Dots (QD) with liquid crystals. QDs are tiny semiconductor particles which are only several nanometers in size. This material has its applications in semiconducting devices with pico-ampere sensitivity and it is able to mimic any biological system.
This system can also store electrical energy more efficiently.
For this specific purpose, the team controlled the assembly of quantum particles in liquid crystal matrix by altering the concentration of QDs. Professor Sandeep Kumar of Raman Research Institute, Bengaluru was responsible for preparing the QDs that were used in this project.
In a conversation with Indian Science Journal, Dr Dharmendra Pratap Singh, the corresponding author of the study and a post doctoral researcher at University of the Littoral Opal Coast in France, said, “This invention opens up development of semiconducting energy storage devices.We are planning to do some more experiments to make a battery for pocket devices using this material by next year.”
Dr. Singh also mentioned that the advantage of the new touch sensitive material is its ability to store more energy in less space, that can be very-utilised for applications like mobile handset, especially new age smartphones.
According to ANI report, the research details have been published in the latest edition of Journal of Physics D: Applied Physics.
Currently, touch sensitive materials are made of liquid crystals on Indium Tin Oxide (ITO) in IPS mode (in-plane switching mode), which means that a device captures traffic for the sensor and then forwards a copy for analysis to the sensor.
Scientists have been trying for some time now to develop organic light emitting diode (OLED) devices which could possibly help in reducing the operating voltage significantly while improving the efficiency and light output.
The five most common types of touch screen technology are : 5-Wire Resistive, Surface Capacitive, ProjectedCapacitive, SAW (Surface Acoustic Wave), and Infrared. The most widely used touch technology today is 5-Wire Resistive Touch.
Resistive touch screens were invented in 1970. A resistive screen basically consists of a number of layers. It functions like this: when the screen is pressed, the mechanism pushes the outer layer onto the next layer, the technology is programmed to sense that pressure being applied and register input.
Resistive touch screens are widely versatile, users can use them with a finger, a fingernail, a stylus or any other object. They are very user-friendly as well.
Capacitive touch screen – a control display that uses the conductive touch of a human finger or a specialized device for input, was designed first but they were eclipsed in the early years of touch-screen technology by the invention of resistive touch screens. A fun fact, American inventor Dr G. Samuel Hurst developed resistive touch screens almost accidentally.

Beijing, December 23, 2016: A gaudy Forbidden City-themed luxury smartphone that comes with an 18-carat gold dragon decoration and a screen made from sapphire glass has evoked criticism from Chinese social media users.
According to the Global Times, the “Titanium Palace Edition” smartphone is expected to be released in January and is priced at 19,999 yuan ($2,880).
NewsGram brings to you current foreign news from all over the world.
Designed in partnership with the Palace Museum, the gem-laden smartphone comes in a limited run of 999 devices.
“Phone makers ‘8488’ partnered with the Palace Museum to create the limited-edition device inspired by the museum’s imperial collections,” the report quoted a company post on Sina Weibo platform as saying.
NewsGram brings to you top news around the world today.
Sina Weibo users called the phone “ostentatious” and a “stain on the sacredness of the imperial city”.
Responding to criticism, the Palace Museum tried to distance itself from the product or its manufacturing.
Check out NewsGram for latest international news updates.
However, earlier this year, Wang Yamin, Vice President of the Palace Museum was quoted by media as saying: “We hope this cooperation will help the Forbidden City enter the tech industry.” (IANS)
