While the flux capacitor still conjures sci-fi images, capacitors are now key components of portable electronics, computing systems, and electric vehicles.

Iranian researchers from Tarbiat Modarres University designed a biosensor that enables the early diagnosis of leukemia in the test sample by using naked eyes. The biosensors have been produced at low cost, and they enjoy high sensitivity, selectivity and speed.

NASA, through its Jet Propulsion Laboratory (JPL) in Pasadena, California, has issued a call to American industry for innovative ideas on how the agency could obtain a core advanced solar electric propulsion-based spacecraft to support the Asteroid Redirect Robotic Mission (ARRM).

Quantum information can be sent optically, that is to say, using light, and the signal is comprised of photons, which is the smallest component (a quantum) of a light pulse. Quantum information is located in whichever path the photon is sent along -- it can, for example, be sent to the right or to the left on a semi-transparent mirror. It can be compared to the use of bits made up of 0s and 1s in the world of conventional computers. But a quantum bit is more than a classical bit, since it is both a 0 and a 1 at the same time and it cannot be read without it being detected, as it is only a single photon. In addition, quantum technology can be used to store far more information than conventional computer technology, so the technology has much greater potential for future information technology.

Airplane accidents are especially dangerous because jet fuel is highly flammable under crash conditions. On impact, jet fuel is dispersed in the air as a fine mist, which triggers a sequence of events that can lead to a fire engulfing an entire plane.

A nano-coil made of graphene could be an effective solenoid inductor for electronic applications, according to researchers at Rice University.

The secret is in a spiral form of atom-thin graphene that, remarkably, can be found in nature, according to Rice theoretical physicist Boris Yakobson and his colleagues.

There is a layer of nanofibers in power plant nanofitlers made by Behran Filter Company," he said about the technical details of the filters. "The nanofilters have smaller pores in comparison with filter papers. Therefore, the efficiency in separation of particles increases while the rate of pressure drop decreases and the life of the filter increases too.

The difference between the results obtained from the model and experimental data is less than that of the previous models. Results of the research have applications in materials engineering, mechanical engineering and aerospace to decrease laboratorial costs.
