Biologists have been experimenting with building materials made with living organisms for years. When will they be used to build our cities?

A new approach to control forces and interactions between atoms and molecules, such as those employed by geckos to climb vertical surfaces, could bring advances in new materials for developing quantum light sources.

“Closely spaced atoms and molecules in our environment are constantly interacting, attracting and repelling each other,” said Zubin Jacob, an assistant professor of electrical and computer engineering at Purdue University. “Such interactions ultimately enable a myriad of phenomena, such as the sticky pads on gecko feet, as well as photosynthesis.”

Typically, these interactions occur when atoms and molecules are between 1 to 10 nanometers apart, or roughly 1/10,000th the width of a human hair.

If you drop your phone and the screen shatters, you usually have two options: get it repaired or replace the phone entirely.

Chemists at the University of California, Riverside, have invented what could become a third option: a phone screen material that can heal itself.

The researchers conducted several tests on the material, including its ability to repair itself from cuts and scratches.

Researchers have probed samples of metal bismuth, and found a completely unexpected property — under certain conditions, the solid metal can retain a type of ‘structural memory’ of its liquid state.

The fact that scientists have found a new property of metals is exciting enough. But this also means solid bismuth can go from being repelled by a magnetic field (diamagnetic) to being attracted to a magnetic field (ferromagnetic), which could lead to a whole new way of creating materials with unique properties.

The phases of matter we learn about in high school, such as liquid, gas, and solid, are all defined by the way molecules in matter are arranged depending on external conditions. For example, liquid water freezes and contracts together, expanding into ice, or relaxes and boils into steam.

Scientist have spotted a strange type of quantum movement occurring in electrons travelling between the atomic layers of a material.

Instead of travelling from the top to the bottom layer through the middle, the electrons were caught disappearing from the top layer and reappearing in the bottom letter a fraction of a second later — with no trace of them existing in between.

“Electrons can show up on the first floor, then the third floor, without ever having been on the second floor,” said lead researcher Hui Zhao from the University of Kansas.

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.

Lawrence Livermore National Laboratory (LLNL) researchers have become the first to 3D print aerospace-grade carbon fiber composites, opening the door to greater control and optimization of the lightweight, yet stronger than steel material.

The research, published by the journal Nature Scientific Reports online on Feb. 28, represents a “significant advance” in the development of micro-extrusion 3D printing techniques for carbon fiber, the authors reported.

A super-material that bends, shapes and focuses sound waves that pass through it has been invented by scientists.

The creation pushes the boundaries of metamaterials — a new class of finely-engineered surfaces that perform nature-defying tasks.

These materials have already shown remarkable results with light manipulation, allowing scientists to create a real-life version of Harry Potter’s invisibility cloak, for example.

(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.
