While graphene has attracted wide interest as a biosensor due to its two-dimensional nature that allows excellent electrostatic control of the transistor channel by the gate
Graphene has been used among other things to design FETSEVICES that regulate the flow of electrons through a channel via a vertical electric field directed into the channel by a terminal called a gate.
In the realm of biosensing the physical gate is removed and the current in the channel is modulated by the binding between embedded receptor molecules and the charged target biomolecules to
whose surface potential (or conductivity) can be modulated by the interaction (known as conjugation) between the receptor and target molecules that results in net accumulation of charges over the gate region.
#New graphene framework bridges gap between traditional capacitors batteries Researchers at the California Nanosystems Institute (CNSI) at UCLA have set the stage for a watershed in mobile energy storage by using a special graphene material

and forming a bridge between the electrodes at the opposite ends of the dielectric material. They demonstrated this process with several metals,
the bridge formed in different ways. The bridge, also called a conducting filament, stays put after the electrical power is turned off in the device.
So when researchers turn the power back on the bridge is there as a smooth pathway for current to travel along.
Further, the electric field can be used to change the shape and size of the filament, or break the filament altogether,

In the usual approach to quantum computing, quantum gates are applied in a specific order, one gate before another.
But it was realized recently that quantum mechanics permits one to"superimpose quantum gates.""If engineered correctly, this means that a set of quantum gates can act in all possible orders at the same time.
Surprisingly, this effect can be used to reduce the total number of gates required for certain quantum computations.
All orders at once A team led by Philip Walther recently realized that superimposing the order of quantum gates, an idea
which was designed theoretically by the group of Caslav Brukner, could be implemented in the laboratory. In a superposition of quantum gate orders, it is impossible--even in principle--to know
if one operation occurred before another operation, or the other way around. This means that two quantum logic gates A and B can be applied in both orders at the same time.
The results of their experiment confirm that it is impossible to determine which gate acted first
"In fact, we were able to run a quantum algorithm to characterize the gates more efficiently than any previously known algorithm,
From a single measurement on the photon, they probed a specific property of the two quantum gates thereby confirming that the gates were applied in both orders at once.
As more gates are added to the task, the new method becomes even more efficient compared to previous techniques.
The Way Forward This is the first time that a superposition of quantum gates has been implemented in the lab. At the same time
