Spintronics


According to Wikipedia, spintronics(also known as fluxtronics ) is defined by the study of the intrinsic spin of the electron.
Basically, it is blend of electronics with spin.

Why should we go for spintronics?     
             Spintronics devices offer   enhanced functionality. Compared to "electronics", spintronics has advantages over it. Imagine I'm using a "spintronic device", for example a laptop :-
• it requires no boot-up waiting period
• it doesn't require a unique and specialized  semiconductor
• it consumes less power
• less heat dissipation
• takes up lesser space on chip, thus more compact
• spin manipulation is faster, which results in good read and write speed(probably faster than present SSD)

After listing these advantages, almost every mind gets questions like "why this is not available in market now ?"
"When can I experience this technology ?"
Bla...bla...and...bla
            Working on spintronics started in late 1980s and still going on. There are challenges faced by  spintronics to come  alive. Like:-
• controlling spin for longer distances
• in most commonly used semiconductor element silicon, controlling spin is very difficult.
•difficult to inject and measure spin
And much more.
       
           Great minds all over the world trying to over come these limitations and bring spintronic devices economical too, so that everyone can afford.
          When we come to application point of view, we can apply spintronics in LEDs, FETs, storage devices, sensors and replace every electronic device. May be in future "electronics" is replaced by "spintronics"


Hope this is helpful and you like it ☺

Stronger,harder,lighter Graphene

Image Source A form of carbon consisting of planar sheets which are one atom thick, with the atoms arranged in a honeycomb shaped lattice                            Wikipedia has a simple definition for graphene , "it is an allotrope of carbon, in the form 2-D atomic scale,hexagonal lattice" Actually, carbon is capable of forming allotropes due to it's valency. Most famous allotropes includes diamond and graphite . Many researches help to discover more forms of carbon in different shapes including ball shapes such as Buckminsterfullerene and sheets such as graphene . Nano tubes, nano ribbons, nano buds comes under large scale structures of carbon. Among these graphene is special. It has got many features like: •it is the thinnest compound known to man at one atom thick •the lightest material •the strongest compound that is discovered (300 times stronger than steel) •best heat and electricity conductor •harder than diamond •the superconducting prope

Future With IoT

The Internet of Things ( IoT ) is the network of things (probably i should call “physical objects”) that has software,sensors, and network connectivity embedded in it, which enables these objects to interact each other and exchange data. The Internet of Things create opportunities for direct integration between the physical world and computer or smartphone-based systems by allowing these objects to be sensed and controlled remotely across existing network infrastructure and resulting in improved efficiency, accuracy. GOOGLE   highlighted the following applications under consideration:  Machine-to-machine communication Machine-to-infrastructure communication Telehealth: remote or real-time pervasive monitoring of patients, diagnosis and drug delivery Continuous monitoring of, and firmware upgrades for, vehicles Asset tracking of goods on the move Automatic traffic management
