Nothing Is Solid & Everything Is Energy – Scientists Explain The World of Quantum Physics

Posted by in categories: energy, quantum physics

What we perceive as our physical material world, is really not physical or material at all, in fact, it is far from it. This has been proven time and time again by multiple Nobel Prize (among many other scientists around the world) winning physicists, one of them being Niels Bohr, a Danish Physicist who made significant contributions to understanding atomic structure and quantum theory.

“If quantum mechanics hasn’t profoundly shocked you, you haven’t understood it yet. Everything we call real is made of things that cannot be regarded as real.” – Niels Bohr

At the turn of the nineteenth century, physicists started to explore the relationship between energy and the structure of matter. In doing so, the belief that a physical, Newtonian material universe that was at the very heart of scientific knowing was dropped, and the realization that matter is nothing but an illusion replaced it. Scientists began to recognize that everything in the Universe is made out of energy.

Self-cleaning Clothes Made Possible By Nano-enhanced Textile

Posted by in categories: energy, nanotechnology

Circa 2016


Not a big fan of laundry day? Well what if you could wash your clothes just by stepping into the sunshine? Thanks to researchers at RMIT University in Melbourne, a self-cleaning textile could make that possible in the very near future. With the help of special nanostructures grown directly into the fabric, these new textiles could degrade organic matter like dirt, dust, and sweat when exposed to a concentrated light source.

To achieve this effect, the nanostructures used by the RMIT University team are made copper and silver. These metals are great at absorbing visible light, and when they’re exposed to light from the sun or even a light bulb, the nanostructures react with increased energy that creates “hot electrons”.

Electron (or ‘hole’) pairs may survive effort to kill superconductivity

Posted by in categories: energy, materials

Scientists seeking to understand the mechanism underlying superconductivity in “stripe-ordered” cuprates—copper-oxide materials with alternating areas of electric charge and magnetism—discovered an unusual metallic state when attempting to turn superconductivity off. They found that under the conditions of their experiment, even after the material loses its ability to carry electrical current with no energy loss, it retains some conductivity—and possibly the electron (or hole) pairs required for its superconducting superpower.

“This work provides circumstantial evidence that the stripe-ordered arrangement of charges and magnetism is good for forming the charge-carrier pairs required for superconductivity to emerge,” said John Tranquada, a physicist at the U.S. Department of Energy’s Brookhaven National Laboratory.

Tranquada and his co-authors from Brookhaven Lab and the National High Magnetic Field Laboratory at Florida State University, where some of the work was done, describe their findings in a paper just published in Science Advances. A related paper in the Proceedings of the National Academy of Sciences by co-author Alexei Tsvelik, a theorist at Brookhaven Lab, provides insight into the theoretical underpinnings for the observations.

Lunar-Polar Propellant Mining Outpost (LPMO): Affordable Exploration and Industrialization

Posted by in categories: energy, space

The Lunar Polar Gas-Dynamic Mining Outpost (LGMO) (see quad chart graphic) is a breakthrough mission architecture that promises to greatly reduce the cost of human exploration and industrialization of the Moon. LGMO is based on two new innovations that together solve the problem of affordable lunar polar ice mining for propellant production. The first innovation is based on a new insight into lunar topography: our analysis suggests that there are large (hundreds of meters) landing areas in small (0.5−1.5 km) nearpolar craters on which the surface is permafrost in perpetual darkness but with perpetual sunlight available at altitudes of only 10s to 100s of meters. In these prospective landing sites, deployable solar arrays held vertically on masts 100 m or so in length (lightweight and feasible in lunar gravity) can provide nearly continuous power.

For hydrogen power, mundane materials might be almost as good as pricey platinum

Posted by in categories: energy, engineering, transportation

As anyone who has purchased jewelry can attest, platinum is expensive. That’s tough for consumers but also a serious hurdle for a promising source of electricity for vehicles: the hydrogen fuel cell, which relies on platinum.

Now a research team led by Bruce E. Koel, a professor of biological and chemical engineering at Princeton University, has opened a door to finding far cheaper alternatives. In a paper published April 4 in the journal Nature Communications, the researchers reported that a chemical compound based on hafnium worked about 60 percent as effectively as -related materials but at about one-fifth the cost.

“We hope to find something that is more abundant and cheaper to catalyze reactions,” said Xiaofang Yang, principal scientist at HiT Nano Inc. and visiting collaborator at Princeton who is working with Koel on the project.

Proton transport ‘highway’ may pave way to better high-power batteries

Posted by in categories: energy, transportation

Researchers at Oregon State University have found that a chemical mechanism first described more than two centuries ago holds the potential to revolutionize energy storage for high-power applications like vehicles or electrical grids.

The research team led by Xiulei (David) Ji of OSU’s College of Science, along with collaborators at the Argonne National Laboratory, the University of California Riverside, and the Oak Ridge National Laboratory, are the first to demonstrate that diffusion may not be necessary to transport ionic charges inside a hydrated solid-state structure of a battery electrode.

“This discovery potentially will shift the whole paradigm of high-power electrochemical energy storage with new design principles for electrodes,” said Xianyong Wu, a postdoctoral scholar at OSU and the first author of the article.

How To Build A Real Lightsaber

Posted by in categories: energy, physics, weapons

As even casual Star Wars fans will know, lightsabers are probably the coolest weapon ever to make an appearance on the big screen. Lightsaber fights are so elegant that they are almost hypnotic and, even though not all of us might have a strong enough flow of Force running through our veins, a lightsaber in the right hand is by far the deadliest weapon to be found in the universe.

The idea behind a lightsaber is simple genius: a light-weight and immensely powerful tool that uses a blade of energy to not only slice up disciples of the Dark Side in a single blow but also act as an effective shield against laser blasts. So why don’t we have working lightsabers in real life? Surely physicists must be smart enough (and big enough Star Wars fans) to be able to produce one of these incredible objects.

How a United Technologies-Raytheon tie-up could make a ‘monster supplier’ and reshape the industry

Posted by in categories: business, energy, military

The combined company, with big footprints in both the fast-growing commercial aerospace business and an increase in military spending, may be emboldened to push back on big customers like Boeing, Airbus and Lockheed Martin in terms of pricing, aftermarket work and intellectual property.


United Technologies has struck a deal to combine its booming aerospace business with defense contractor Raytheon, a surprise twist capable of rattling customers and competitors alike.

The deal would create a giant, one-stop shop with products that range from Tomahawk missiles and radar systems to jet engines that power passenger planes and the seats that fill them.
