Thinnest bulb in the world

Scientists have demonstrated, for the first time, an on-chip visible light source using graphene as a filament. They attached small strips of graphene to metal electrodes, suspended the strips above the substrate, and passed a current through the filaments to cause them to heat up. This was achieved by James Hone’s group at Columbia Engineering, a team of scientists from Columbia University, Seoul National University (SNU), and Korea Research Institute of Standards and Science (KRISS), led by Young Duck Kim, a postdoctoral research scie

Technology can make Night visions and thermal imaging devices affordable to all

Semiconductor technology that could make night vision and thermal imaging affordable for everyday use was created by Engineers at the University of Texas at Dallas.Researchers in the Texas Analog Center of Excellence (TxACE) in the university’s Erik Jonsson School of Engineering and Computer Science created an electronic device that detects electromagnetic waves to create images at nearly 10 THz, which is the highest frequency for electronic devices. The device could cut off the cost of night visions and thermal imaging devices. T

PPT on 8251 USART(Universal Synchronous Asynchronous Receiver Transmitter)

The 8251 USART is typically used for serial communication and was rated for 19.2 Kilo bits per second signalling rate.It is commonly confused with the much more common 8250 UART that was made popular as the serial port in the IBM Personal Computer. It has 5 sections: read/write control logic transmitter receiver data bus system modem control Contents of ppt: INTRODUCTION SYNCHRONOUS COMMUNICATION ASYNCHRONOUS COMMUNICATION BLOCK DIAGRAM TRANSMITTER RECEIVER PIN DIAGRAM PIN DESCRIPTION APPLICATIONS PPT:                                                   Related posts:Ppt on proximity

Now smartphones can be used by touching your skin

People wearing a smartwatch can look at the calender or receive emails without having to reach further than their wrist. However, the interaction area offered by the watch is so small that sometimes it's really difficult to tap the individual buttons precisely. A team of computer scientists from Saarbrucken in collaboration with researchers from Carnegie Mellon University in the USA may provide a solution to this problem, they have created a flexible sensor that could be stuck to the skin and used to control your phone.These touch-sensitive

Silicene holds the promise for super-fast computer chips

One atom thick layer of silicon atoms is called as Silicene. Researchers at the University of Texas at Austin's Cockrell School of Engineering have created the first transistors made of silicene, the world’s thinnest silicon material.Their research holds the promise of building dramatically faster, smaller and more efficient computer chips. Silicene has outstanding electrical properties but has until now proved difficult to produce and work with.One of the major challenges surrounding silicene was solved by Deji Akinwand

Transparent display, a definite possibility

Responsive transparent displays that don't need an internal light source and can be easily integrated on windows and glasses can be made using the optical features embedded in marine shells. The scientists at MIT and Havard have identified two optical structures within the limpet's( it is an aquatic snail with a shell broadly conical in shape) shell that give its blue stripped appearance.The structures are configured to reflect blue light while absorbing all other wavelengths of incoming light.The findings in the journal Nature Co

Great future plans for QR codes

QR(quick response) code are those which are usually in black and white boxes that people scan with their mobile phones to download or to know more about something.The researchers from the  University of Connecticut says that these can even take care of national security. Board of Trustees Distinguished Professor Bahram Javidi said that “An optical code or QR code can be manufactured in such a way that it is very difficult to duplicate,”. “But if you have the right keys, not only can you authenticate the chip, b

Future of quantum radar

An international research team led by a quantum information scientist at the University of York built a prototype quantum radar that has the potential to detect objects that are invisible to conventional systems. This new breed of radar is a hybrid system which uses quantum correlation between microwave and optical beams to detect the objects that has low reflectivity such as cancer cells or aircraft. The radar operates at lower energies compared to the conventional systems and therefore it has a long-term potential for numerous a

Now 3-D displays without glasses is possible

Thanks to a new invention from Austrian scientists, in the future we will be able to enjoy public screenings in 3-D, which have become an important part of major sports events. A sophisticated laser system sends laser beams into different directions due to which different pictures are visible at different angles and the angular resolution is so fine that the left eye sees a different picture than the right one which creates a 3-D effect. In 2013, a startup company TriLite Technologies had the idea to develop this new kind of displ

3D-print jet engines

Researchers for the first time in the world, printed two jet engines using sophisticated 3D printers that can make complex objects using metals like titanium and aluminium.This has attracted the interest of major manufacturers and engineering firms.The machines produced using the template of a gas turbine engine from French aircraft engine maker Safran, which supplies Airbus and Boeing-demonstrated the potential 3D printing had to produce high-quality products, researchers from Melbourne's Monash University said. The university's Ian Smit

NEMS lab on a chip revolution set by Optical nanoantennas

Australian scientists created tiny antennas, likened to spotlights on the nanoscale which offers the potential to measure food safety, identify pollutants in the air and even quickly diagnose and treat cancer.The new antennas are cubic in shape and it does a better job than the previous spherical ones at directing an ultra-narrow beam of light, with little or no loss due to heating and scattering.

Armband that can sound alarm if you have fever

Japanese researchers have developed a armband that produces sound if you have fever. It is flexible, self-powered, wearable device that goes of in case of  high body temperature. The flexible organic components developed for this device are well-suited to wearable devices that continuously monitor vital signs including temperature and heart rate for applications in healthcare. Professor Takao Someya from the University of Tokyo's graduate school of engineering says that "The fever alarm armband demonstrates that it is possible to produc

Fibre based electronic devices : Seminar topic

Weaving of electronics into any material Scientists have always been known for doing impossible things and now a group of scientists from Massachusetts Institute of Technology (MIT) have done yet another thing by using two abundant raw materials to create fibre of pure crystalline silicon which could be used to add electronics, including microchips and solar cells, to almost any fabric. The idea grew out of a long-term research effort to develop multifunctional fibres that incorporate different materials into a single long functional st

Gold Nanotubes : Seminar Topic

A demonstration of the biomedical use of gold nanotubes in a mouse model of human cancer was conducted successfully and soon it would be heading for clinical trials. High recurrence rates of tumours after surgical removal remain a formidable challenge in cancer therapy. Chemo or radiotherapy is often given following surgery to prevent this, but these treatments cause serious side effects. Gold nanotubes resembles tiny drinking straws and have the potential to enhance the efficiency of these conventional treatments by integrating diagnos
