Applied Technotopia

We scan the digital environment to examine the leading trends in emerging technology today to know more about future.

We have added a few indices around the site. Though we look to the future, we need to keep an eye on the present as well:

Material science advances towards cloaked invisibility for materials.(So, when will the first “Bird of Prey” be built?)


The Vanishing Cat And Other Tales Of The Invisibility Cloak

by Txchnologist staff

"Any sufficiently advanced technology is indistinguishable from magic." -Arthur C. Clarke

Soon, Harry Potter won’t be the only person with an invisibility cloak. A paper published this week in Nature outlines a new design for cloaking devices that uses commonly available materials and can be built big. The design has already been used successfully to hide living creatures, including a cat and a fish.

A look at e-skin and its uses.


Paper thin ‘e-skin’ developed.

An electronic skin created at UC Berkeley responds to touch by lighting up, with the light intensity getting brighter with harder touch. By using existing techniques currently used to create semiconductors, the team was able to fabricate the skin into a paper-thin piece of flexible polymer, integrating a transistor, organic LED, and a pressure sensor into each ‘pixel’, maintaining enough flexibility for the skin to be bent and flexed.

The skin could find uses ranging from a bandage that works as a health monitor which lights up to show blood pressure and pulse rates, to being used to give robots a finer sense of touch.

The team now hopes to make similar skins which respond to not only touch, but also light and pressure.

A great breakthrough in building material using concrete as made in Ancient Rome.

After 2,000 years, a long-lost secret behind the creation of one of the world’s most durable man-made creations ever—Roman concrete—has finally been discovered by an international team of scientists, and it may have a significant impact on how we build cities of the future.

A rather unusual advance in material sciences.


Discovery of New Material State Counterintuitive to Laws of Physics

June 12, 2013 — When you squeeze something, it gets smaller. Unless you’re at Argonne National Laboratory.

At the suburban Chicago laboratory, a group of scientists has seemingly defied the laws of physics and found a way to apply pressure to make a material expand instead of compress/contract.

“It’s like squeezing a stone and forming a giant sponge,” said Karena Chapman, a chemist at the U.S. Department of Energy laboratory. “Materials are supposed to become denser and more compact under pressure. We are seeing the exact opposite. The pressure-treated material has half the density of the original state. This is counterintuitive to the laws of physics.”

Because this behavior seems impossible, Chapman and her colleagues spent several years testing and retesting the material until they believed the unbelievable and understood how the impossible could be possible. For every experiment, they got the same mind-bending results.

“The bonds in the material completely rearrange,” Chapman said. “This just blows my mind.”

This discovery will do more than rewrite the science text books; it could double the variety of porous framework materials available for manufacturing, health care and environmental sustainability.

Scientists use these framework materials, which have sponge-like holes in their structure, to trap, store and filter materials. The shape of the sponge-like holes makes them selectable for specific molecules, allowing their use as water filters, chemical sensors and compressible storage for carbon dioxide sequestration of hydrogen fuel cells. By tailoring release rates, scientists can adapt these frameworks to deliver drugs and initiate chemical reactions for the production of everything from plastics to foods.

“This could not only open up new materials to being porous, but it could also give us access to new structures for selectability and new release rates,” said Peter Chupas, an Argonne chemist who helped discover the new materials.

The team published the details of their work in the May 22 issue of the Journal of the American Chemical Society in an article titled “Exploiting High Pressures to Generate Porosity, Polymorphism, And Lattice Expansion in the Nonporous Molecular Framework Zn(CN)2 .”

The scientists put zinc cyanide, a material used in electroplating, in a diamond-anvil cell at the Advanced Photon Source (APS) at Argonne and applied high pressures of 0.9 to 1.8 gigapascals, or about 9,000 to 18,000 times the pressure of the atmosphere at sea level. This high pressure is within the range affordably reproducible by industry for bulk storage systems. By using different fluids around the material as it was squeezed, the scientists were able to create five new phases of material, two of which retained their new porous ability at normal pressure. The type of fluid used determined the shape of the sponge-like pores. This is the first time that hydrostatic pressure has been able to make dense materials with interpenetrated atomic frameworks into novel porous materials. Several series of in situ high-pressure X-ray powder diffraction experiments were performed at the 1-BM, 11-ID-B, and 17-BM beamlines of the APS to study the material transitions.

“By applying pressure, we were able to transform a normally dense, nonporous material into a range of new porous materials that can hold twice as much stuff,” Chapman said. “This counterintuitive discovery will likely double the amount of available porous framework materials, which will greatly expand their use in pharmaceutical delivery, sequestration, material separation and catalysis.”

The scientists will continue to test the new technique on other materials.

The research is funded by the U.S. Department of Energy’s Office of Science.
