Mixing Polymer fiber and carbon nanotubes to make cheap material that is twice as strong as Kevlar

Traditionally, carbon fibers are made by “carbonizing” a polymer called poly-acrylonitrile, or PAN. First, the polymer is spun into a fiber and then it is heated to very high temperatures. This causes the polymer molecules to to be converted into a homogenous carbon structure, causing the material to become a stiff solid. Some research groups …

PBS shows off 1.8 gigapixel video feed and analysis from a DARPA drone

From an altitude of 17,500 feet a drone with a 1.8 gigapixel video camera can monitor half of Manhattan. The interface shows the wide field of view all at once but 65 windows can be opened up showing zoom in views of different spots. They can see things as small as 6 inches like birds. …

Impulse Drive – Mach Effect Thruster

The Mach Effect Thruster (MET) is a device which utilizes fluctuations in the rest masses of accelerating objects (capacitor stacks, in which internal energy changes take place) to produce a steady linear thrust. The theory has been given in detail elsewhere and references therein, so here we discuss only an experiment. We show how to …

Carnival of Space 287

1. Meridiani Journal – Astronomers redefine the habitable zone for exoplanets. Astronomers, from Penn State and also collaborators with the Planetary Habitability Laboratory, have concluded that, overall, the habitable zones are a bit farther out from their stars than previously thought. “This has implications for finding other planets with life on them,” according to Ravi …

Joe Eck Reports 35 Celsius Superconductor after substituting Silicon

Superconductors.ORG (Joe Eck) reports the 30 Celsius superconductor discovered in December 2012 has been successfully reformulated to advance high Tc to above 35 Celsius (95F, 308K). This was accomplished with a simple substitution of tetravalent silicon into the magnesium atomic sites. The chemical formula thus becomes Tl5Pb2Ba2Si2.5Cu8.5O17+. This is the third material discovered with a …

Towards defect-free graphene and large scale manufacturing

A new way of growing graphene without the defects that weaken it and prevent electrons from flowing freely within it could open the way to large-scale manufacturing of graphene-based devices with applications in fields such as electronics, energy, and healthcare. A team led by Oxford University scientists has overcome a key problem of growing graphene …

Genetically modified tobacco plants produce antibodies to treat rabies

In a new research report appearing in The FASEB Journal, scientists produced a monoclonal antibody in transgenic tobacco plants that was shown to neutralize the rabies virus. This new antibody works by preventing the virus from attaching to nerve endings around the bite site and keeps the virus from traveling to the brain. “Rabies continues …

Towards Printable photonic devices with sub-10 nm resolution

The researchers are using nanoimprinting and have already produced 5 nanometer lines and they believe they can scale it up to commercial applications. A novel and robust route for high-throughput, high-performance nanophotonics-based direct imprint of high refractive index and low visible wavelength absorption materials is presented. Sub-10 nm TiO2 nanostructures are fabricated by low-pressure UV-imprinting …
