Arxiv – Observation of the Meissner effect at room temperature in single-layer graphene brought into contact with alkanes

There are claims of synthesis of a room temperature superconductor. However, these claims have not been officially accepted by scientific communities. Currently, the highest transition temperature (Tc) recognized in scientific articles is 135 K at 1 atm of Hg-Ba-Ca-Cu-O system which is a copper oxide superconductor. We packed graphite flakes into a ring-shaped polytetrafluoroethylene (PTFE) tube and further injected heptane or octane. Then we generated circulating current in this ring tube by electromagnetic induction and showed that this circulating current continues to flow continuously at room temperature for 50 days. This experiment suggests that bringing alkane into contact with graphite may result in a material with zero resistance at room temperature.

UC Berkeley engineers have given new meaning to the term “working paper.” Using inexpensive materials, they have fabricated foldable electronic switches and sensors directly onto paper, along with prototype generators, supercapacitors and other electronic devices for a range of applications.

Research to develop paper electronics has accelerated in the last 10 years. Besides its availability and low cost, paper offers an intriguing potential: simply folding it could switch circuits on and off or otherwise change their activity—a kind of electronic origami.

But most efforts to fabricate electrodes onto paper with sufficient conductivity for practical use have employed expensive metals such as gold or silver as the conducting material, swamping the potential savings of paper as a substrate.

Scientists have injected spider DNA into goats to create a bulletproof material! #DCode

Tokamak Energy of the UK has built the ST40 prototype fusion reactor and they aim to reach 100 million degrees celsius by the end of 2018. They have already reached 15 million degrees.

By sealing up traumatic injuries or delivering crucial medications.

Aside from dark matter and the dark energy that comprised the universe, there remained to be 5 percent of what was called the “ordinary matter.” About two-thirds of this ordinary matter was left unaccounted for until now. ( Harvard-Smithsonian Center for Astrophysics )

After a 20-year-long experiment, a team of international scientists detects the last of the missing intergalactic material predicted to be created by the Big Bang.

Specifically, the team was finally able to detect the missing parts of the “ordinary matter” that makes up everything in the universe, from the stars to the cores of black holes. This ordinary matter is different from the “dark matter” that comprised the bulk of the universe’s mass. The dark matter remained to be undetected until now.

Infrared cameras are the heat-sensing eyes that help drones find their targets, even in the dead of night or through heavy fog.

Hiding from such detectors could become much easier, thanks to a new cloaking material that renders objects—and people—practically invisible.

“What we have shown is an ultrathin stealth ‘sheet.’ Right now, what people have is much heavier metal armor or thermal blankets,” says Hongrui Jiang, the Lynn H. Matthias Professor and Vilas Distinguished Achievement Professor of electrical and computer engineering at the University of Wisconsin-Madison.
