Superlubricity nano-structured self-assembling coating repairs surface wear, decreases emissions and increases HP and gas mileage.

Globally about 15 percent of manmade carbon dioxide comes from vehicles. In more developed countries, cars, trucks, airplanes, ships and other vehicles account for a third of emissions related to climate change. Emissions standards are fueling the lubricant additives market with innovation.

Up to 33% of fuel energy in vehicles is used to overcome friction. Tribology is the science of interacting surfaces in relative motion inclusive of friction, wear and lubrication. This is where TriboTEX, a nanotechnology startup is changing the game of friction modification and wear resilience with a lubricant additive that forms a nano-structured coating on metal alloys.

This nano-structured coating increases operating efficiency and component longevity. It is comprised of synthetic magnesium silicon hydroxide nanoparticles that self-assemble as an ultralow friction layer, 1/10 of the original friction resistance. The coating is self-repairing during operation, environmentally inert and extracts carbon from the oil. The carbon diamond-like nano-particle lowers the friction budget of the motor, improving fuel economy and emissions in parallel while increasing the power and longevity of the motor.

TriboTEX has a Kickstarter campaign that has just surpassed $100,000 in funding. The early bird round has just closed that offered the product at one half the cost of its retail. The final round offers the lubricant system self-forming coating at 75 percent and is ending shortly. The founder Dr. Pavlo Rudenko, Ph.D. is a graduate of Singularity University GSP11 program.

Great news and a very promising vector for near future innovation!

A research team led by the University of Minnesota has discovered a way to rewarm large-scale animal heart valves and blood vessels preserved at very low (cryogenic) temperatures without damaging the tissue. The discovery could one day lead to saving millions of human lives by creating cryogenic tissue and organ banks of organs and tissues for transplantation.

Inspired by origami, North Carolina State University researchers have found a way to remotely control the order in which a two-dimensional (2-D) sheet folds itself into a three-dimensional (3D) structure.

“A longstanding challenge in the field has been finding a way to control the sequence in which a 2-D sheet will fold itself into a 3D object,” says Michael Dickey, a professor of chemical and biomolecular engineering at NC State and co-corresponding author of a paper describing the work. “And as anyone who has done origami — or folded their laundry—can tell you, the order in which you make the folds can be extremely important.”

Washington State University researchers have developed a unique, 3D manufacturing method that for the first time rapidly creates and precisely controls a material’s architecture from the nanoscale to centimeters. The results closely mimic the intricate architecture of natural materials like wood and bone.

They report on their work in the journal Science Advances and have filed for a patent.

The work has many high-tech engineering applications.

Frozen organs could be brought back to life safely one day with the aid of nanotechnology, a new study finds. The development could help make donated organs available for virtually everyone who needs them in the future, the researchers say.

The number of donated organs that could be transplanted into patients could increase greatly if there were a way to freeze and reheat organs without damaging the cells within them.

In the new work, scientists developed a way to safely thaw frozen tissues with the aid of nanoparticles — particles only nanometers or billionths of a meter wide. (In comparison, the average human hair is about 100,000 nanometers wide.)

Researchers announce a potential breakthrough in using nanotechnology to fight cancer.

(Phys.org)—Scientists have found that a superconducting current flows in only one direction through a chiral nanotube, marking the first observation of the effects of chirality on superconductivity. Until now, superconductivity has only been demonstrated in achiral materials, in which the current flows in both directions equally.

The team of researchers, F. Qin et al., from Japan, the US, and Israel, have published a paper on the first observation of chiral superconductivity in a recent issue of Nature Communications.

Chiral superconductivity combines two typically unrelated concepts in a single material: Chiral materials have mirror images that are not identical, similar to how left and right hands are not identical because they cannot be superimposed one on top of the other. And superconducting materials can conduct an electric current with zero resistance at very low temperatures.

Researchers at the University of Minnesota and University of Milano-Bicocca are bringing the dream of windows that can efficiently collect solar energy one step closer to reality thanks to high tech silicon nanoparticles.

The researchers developed technology to embed the silicon nanoparticles into what they call efficient luminescent solar concentrators (LSCs). These LSCs are the key element of windows that can efficiently collect solar energy. When light shines through the surface, the useful frequencies of light are trapped inside and concentrated to the edges where small solar cells can be put in place to capture the energy.

The research is published today in Nature Photonics.

Lawrence Livermore scientists have collaborated with an interdisciplinary team of researchers including colleagues from Sandia National Laboratories to develop an efficient hydrogen storage system that could be a boon for hydrogen powered vehicles.

Hydrogen is an excellent energy carrier, but the development of lightweight solid-state materials for compact, low-pressure storage is a huge challenge.
