#MIT Physicists Create a Superfluid in a Record-High Magnetic field Physicists from MIT have created a superfluid gas, the so-called Bose-Einstein condensate, for the first time in an extremely high magnetic field.
The magnetic field is a synthetic magnetic field, generated using laser beams, and is 100 times stronger than that of the world strongest magnets.
Within this magnetic field, the researchers could keep a gas superfluid for a tenth of a second just long enough for the team to observe it.
Superfluids are thought to flow endlessly, without losing energy, similar to electrons in a superconductor. Observing the behavior of superfluids
to create and maintain a superfluid gas long enough to observe it at ultrahigh synthetic magnetic fields. oing to extremes is the way to make discoveries,
The electric field of the laser beams creates what known as a periodic potential landscape, similar to an egg carton,
When charged particles are exposed to magnetic fields, their trajectories are bent into circular orbits, causing them to loop around and around.
The higher the magnetic field, the tighter a particle orbit becomes. However, to confine electrons to the microscopic scale of a crystalline material,
a magnetic field 100 times stronger than that of the strongest magnets in the world would be required.
their trajectories are unaffected normally by magnetic fields. Instead, the MIT group came up with a technique to generate a synthetic
ultrahigh magnetic field, using laser beams to push atoms around in tiny orbits, similar to the orbits of electrons under a real magnetic field.
In this scenario, atoms could only move with the help of laser beams. ow the laser beams could be used to make neutral atoms move around like electrons in a strong magnetic field
or loop around, in a radius as small as two lattice squares, similar to how particles would move in an extremely high magnetic field. nce we had the idea,

#Graphene"Decorated"With Lithium Becomes a Superconductor Graphene is a conductor unlike anything seen before.
nobody had been able to make graphene behave as a superconductor, until now. An international research team from Canada and Germany has been able to demonstrate that graphene can be made to behave as a superconductor
when it doped with lithium atoms. The researchers believe that this new property could lead to a new generation of superconducting nanoscale devices.
Superconductors are materials that conduct electricity without resistance and without dissipating energy. In ordinary materials, electrons repel each other,
but in superconductors the electrons form pairs known as Cooper pairs, which together flow through the material without resistance.
Graphene is not naturally a superconductor, and neither is its three-dimensional sourceraphite. However, it was demonstrated a decade ago that graphite could be induced into behaving like a superconductor.
If it possible with graphite it should be with graphene, right? Other research groups believed
The key observation was increased that this number of coupled pairs led to superconductivity, which the researchers measured by identifying an energy gap between the material's conducting and nonconducting electrons.
The researchers who demonstrated last year the role phonons played in the superconductivity of graphite and calcium, Patrick Kirchmann and Shuolong Yang of the SLAC National Accelerator Laboratory
believe this latest work could usher in the fabrication of nanoscale superconducting quantum interference devices and single-electron superconductor quantum dots u

#MIT's 3-D Microwave Camera Can See through Walls Visible light is all well and good for things like eyeballs,
At MIT, theye been working on a prototype for a time of flight microwave camera which can be used to image objects through walls,
in 3-D. A microwave camera is sort of like a cross between a visible light camera and a radar imaging system,
Like radar, microwaves don really notice things like darkness or fog or walls, but unlike radar theye not confused by the kinds of angled surfaces that make the stealth fighter so stealthy.
essentially treating microwaves like waves of light and using a passive reflector like a lens,
MIT microwave camera can do 3-D imaging using time of flight in the same way that Microsoft latest Xbox Kinect sensor works.
The time of flight camera sends out bursts of microwaves and then keeps careful track of how long it takes for the microwaves to bounce off of something
and return to the sensor. After doing some not very fancy math with the speed of light,
Here's a video showing the microwave camera taking pictures of (among other things) a mannequin through a solid wall:
wee very good at reflecting microwaves in this frequency range because wee ugly bags of mostly water,
One other trick that the microwave camera is capable of is multispectral imaging. As the camera takes each measurement
the microwave emitter sweeps through a frequency range of 7. 835 GHZ to 12.817 GHZ over 10 ms (your microwave oven operates at 2. 45 GHZ.
Different materials respond to the microwaves differently at lower and higher frequencies, and the camera can separate out these spectra.
The microwave camera is, at the moment, probably not something that you want to carry around. The reflector is over a meter wide,
including the use of reconfigurable focal-plane sensors or shrinking the transmission wavelength from microwave (3 cm) down to millimeter wave (5 mm),
the frequency is high enough that the plasma breakdown threshold for surface electric fields increases The terahertz approach also allows them to use readily available picoseconds lasers.

#Electroluminescence with Phosphor Nanoparticles Holds Promise for Modern Lighting Light-emitting diodes (LEDS) are the modern lighting devices used in lamps, signals, signs or displays.
One promising alternative for modern lighting is electroluminescence. Special nanoparticles, so-called phosphors, are excited in an electric field to emit light.
Researchers at the INM Leibniz Institute for New Materials have developed now a new method that enables electroluminescence on large
curved surfaces in a cost-effective way: in this case, the light-emitting layer and all other components are produced by means of wet-chemical, printable methods.
On application of an AC voltage, light is emitted from the electroluminescent layer. e embed luminous particles in the form of functionalized zinc sulphide nanoparticles as phosphors into the binder layer,
The electroluminescent light sheets developed at the INM can be connected directly to the customary mains voltage of 230 volts.
For example, the chemistry of the hydrogel can be modified to respond to changes in temperature, light, electric and magnetic fields,
Conventional biomolecule sorting systems rely on external electric fields infrared radiation, and magnetic fields, and often require chemical modifications of the biomolecules of interest.
That means setups can be used only once or require a series of sequential steps. In contrast, said Ankita Shastri, a graduate student in Chemistry and Chemical Biology at Harvard and a member of Aizenberg group,

These batteries typically contain cathode particles through which the electrons flow, an action that enables the battery to charge.
These cathode particles are composed typically of lithium iron phosphate or lithium cobalt oxide, mixed together with carbon black,
Ultimately, the rate at which a cathode particle charges depends on how well it is connected to carbon black particles,
"Li said that by upping the percentage of carbon black as high as 20 percent in some experiments they found that the cathode particles charged more quickly
Increasing the percentage of carbon black decreased the amount of cathode particles available to hold a charge.
because it has fewer cathode particles to hold the charge.""It's about finding the optimum balance and the best material,
For instance, its electrical conductivity increases as the number of stored water molecules rises. This is what enables it to serve as a measure of ambient moisture.

#Magnetic Signals Sent through the Human body for Wireless communication Electrical engineers at the University of California, San diego demonstrated a new wireless communication technique that works by sending magnetic signals through the human body.
"In this study, electrical engineers demonstrated a technique called magnetic field human body communication, which uses the body as a vehicle to deliver magnetic energy between electronic devices.
An advantage of this system is that magnetic fields are able to pass freely through biological tissues,
Researchers showed that the path losses associated with magnetic field human body communication are upwards of 10 million times lower than those associated with Bluetooth radios."
With this magnetic field human body communication system, we hope to significantly reduce power consumption as well as how frequently users need to recharge their devices,
Another potential advantage of magnetic field human body communication is that it could offer more security than Bluetooth networks.
On the other hand, magnetic field human body communication employs the human body as a communication medium, making the communication link less vulnerable to eavesdropping.
Demonstrating magnetic communication with a proof-of-concept prototype The researchers built a prototype to demonstrate the magnetic field human body communication technique.
These coils serve as sources for magnetic fields and are able to send magnetic signals from one part of the body to another using the body as a guide.
Researchers noted that a limitation of this technique is that magnetic fields require circular geometries in order to propagate through the human body.
Devices like smart watches, headbands and belts will all work well using magnetic field human body communication
