Graphene-Based Electronics: Can This Replace Silicon Microelectronics, Semiconductors?

Posted by in categories: chemistry, materials

Finding a material that could replace silicon is a critical task in nanoelectronics. For many years, graphene has appeared promising. However, its potential was compromised along the way because of destructive processing techniques and the absence of a new electronics paradigm to adopt it. The need for the next major nanoelectronics platform is greater than ever, as silicon is almost at its limit in supporting faster computation.

The strength of graphene, according to Walter de Heer, a professor at the Georgia Institute of Technology’s School of Physics, rests in its flat, two-dimensional structure, which is kept together by the strongest chemical bonds known.

Scientists Made a ‘Fish’ From Human Cardiac Cells, And It Swims Like a Beating Heart

Posted by in category: energy

With its tail flipping rhythmically from side to side, this strange synthetic fish scoots around in its salt and glucose solution, using the same power as our beating hearts.

This nifty miniaturized circulatory system, developed by scientists at Harvard and Emory universities, can keep swimming to the beat for more than 100 days.

The lifelike statue of Kaaper the scribe is the oldest life-size wooden statue from Ancient Egypt

Posted by in category: futurism

In 1,860, Auguste Mariette unearthed an exceptional sculpture while excavating a mastaba in the Saqqara necropolis, north of the Step Pyramid of Djoser.

Egyptian workers quickly realized the uniqueness of the discovery and, impressed by its realism, named it Sheikh el-Beled (Arabic for the village head, that is, the mayor), possibly because it reminded them of someone from their locality.

It actually represents Kaaper, an Egyptian nobleman who lived in the late fourth or early fifth dynasty (circa 2500 BC); the mastaba (today called the Kaaper mastaba or Saqqara C8) was the burial place of his family. Since that, another sculpture of what is believed to be his wife was also found, although the name has not been preserved.

Quasicrystal formed during accidental electrical discharge

Posted by in category: particle physics

A team of researchers from Università di Firenze, the University of South Florida, California Institute of Technology and Princeton University has found an incidence of a quasicrystal formed during an accidental electrical discharge.

In their paper published in Proceedings of the National Academy of Sciences, the group describes their study of a quasicrystal found in a in Nebraska.

Quasicrystals, as their name suggests, are crystal-like substances. They possess characteristics not found in ordinary crystals, such as a non-repeating arrangement of atoms. To date, quasicrystals have been found embedded in meteorites and in the debris from nuclear blasts. In this new effort, the researchers found one embedded in a sand dune in Sand Hills, Nebraska.
