His lab is dedicated to an idea called frugal innovation: “How do you do very high-level science or engineering with very little?” said Thuo, an assistant professor of materials science and engineering at Iowa State University and an associate of the U.S. Department of Energy’s Ames Laboratory. “How can you solve a problem with the least amount of resources?”

That goal has Thuo and his research group using their materials expertise to study soft matter, single-molecule electronics and renewable energy production. A guiding principle is that, whenever possible, nature should do part of the work.

“Nature has a beautiful way of working for us,” he said. “Self-assembly and ambient oxidation are great tools in our designs.”

(Phys.org)—For the past 17 years, spiro-OMeTAD, has been keeping a secret. Despite intense research efforts, its performance as the most commonly used hole-transporting material in perovskite and dye-sensitized solar cells has remained stagnant, creating a major bottleneck for improving solar cell efficiency. Thinking that the material has given all it has to offer, many researchers have begun investigating alternative materials to replace spiro-OMeTAD in future solar cells.

But in a new study published in Science Advances, Dong Shi et al. have taken a closer look at spiro-OMeTAD and found that it still has a great deal of untapped potential. For the first time, they have grown single crystals of the pure material, and in doing so, they have made the surprising discovery that spiro-OMeTAD’s single-crystal structure has a hole mobility that is three orders of magnitude greater than that of its thin-film form (which is currently used in solar cells).

“This paper reports a major breakthrough for the fields of perovskite and solid-state by finally clarifying the potential performance of the material and showing that improving the crystallinity of the hole transport layer is the key strategy for further breakthroughs in device engineering of these solar cells,” Osman Bakr, a professor of engineering at King Abdullah University of Science and Technology (KAUST) in Saudi Arabia and leader of the study, told Phys.org.

Good luck convincing business and consumers to buy your autonomous spider-bot.

There are a number of major tech-driven companies that are researching 3D printing technology at a rapid rate, but very few invest as much as time and money into additive manufacturing as Siemens does. Whether they’re building their own €21.4 million metal 3D printing facility or helping 3D printing startups with their endeavors, the global engineering company is betting big within the 3D printing industry. Now, a research team from Siemens Corporate Technology’s Princeton campus has just revealed their latest innovation, the development of autonomous mobile 3D printing devices, which are being called spider-bots.

These unique printing devices, which look like spider-like robots, were almost entirely designed and manufactured by the Siemens Corporate Technology research team. They’re engineered with an extruder similar to the type used with FDM printing, and are able to print in polylactic acid (PLA). The spider-bots are equipped with an onboard camera and a laser scanner as well, which enables them to become aware of the surrounding environment during the print job. Software-wise, they’re all programmed with a modified version of Siemens’ NX PLM software, which is their product development, engineering, and manufacturing software solution. In the near-future, the Siemens research team hopes to utilize these spider-bots within the automotive and aerospace industries.

Many think author, inventor and data scientist Ray Kurzweil is a prophet for our digital age. A few say he’s completely nuts. Kurzweil, who heads a team of more than 40 as a director of engineering at Google, believes advances in technology and medicine are pushing us toward what he calls the Singularity, a period of profound cultural and evolutionary change in which computers will outthink the brain and allow people—you, me, the guy with the man-bun ahead of you at Starbucks—to live forever. He dates this development at 2045.

Raymond Kurzweil was born February 12, 1948, and he still carries the plain, nasal inflection of his native Queens, New York. His Jewish parents escaped Hitler’s Austria, but Kurzweil grew up attending a Unitarian church. He worshipped knowledge above all, and computers in particular. His grandmother was one of the first women in Europe to earn a Ph.D. in chemistry. His uncle, who worked at Bell Labs, taught Ray computer science in the 1950s, and by the age of 15, Kurzweil was designing programs to help do homework. Two years later, he wrote code to analyze and create music in the style of various famous composers. The program won him the prestigious Westinghouse Science Talent Search, a prize that got the 17-year-old an invitation to the White House. That year, on the game show I’ve Got a Secret, Kurzweil pressed some buttons on a data processor the size of a small car. It coughed out original sheet music that could have been written by Brahms.

After earning degrees in computer science and creative writing at MIT, he began to sell his inventions, including the first optical character recognition system that could read text in any normal font. Kurzweil knew a “reading machine” could help the blind, but to make it work, he first had to invent a text-to-speech synthesizer, as well as a flatbed scanner; both are still in wide use. In the 1980s Kurzweil created the first electronic music keyboard to replicate the sound of a grand piano and many other instruments. If you’ve ever been to a rock concert, you’ve likely seen the name Kurzweil on the back of a synthesizer.

A new generation of muon telescopes has been built to detect the presence of secret structures and cavities in Egypt’s pyramids, a team of researchers announced on Friday.

Built by CEA (French Alternative Energies and Atomic Energy Commission) the devices add to an armory of innovative, non-destructive technologies employed to investigate four pyramids which are more than 4,500 years old. They include the Great Pyramid, Khafre or Chephren at Giza, the Bent pyramid and the Red pyramid at Dahshur.

The project, called ScanPyramids, is scheduled to last one year and is being carried out by a team from Cairo University’s Faculty of Engineering and the Paris-based non-profit organization Heritage, Innovation and Preservation (HIP Institute) under the authority of the Egyptian Ministry of Antiquities.

“This book considers two key educational tools for future generations of professionals with a space architecture background in the 21st century: (1) introducing the discipline of space architecture into the space system engineering curricula; and (2) developing space architecture as a distinct, complete training curriculum.”

Australia is making great strides in this area as well.

Scientists are racing to deploy foolproof quantum encryption before quantum computers come along that render all our passwords useless.

Passwords work today because the computers we have, while theoretically capable of breaking passwords, would take an impractical amount of time to do so.

“The encryption schemes today are based on factoring and on prime numbers, so if you had a computer that could factor instantly, if it did that today it could break all encryption schemes,” said David Awshalom, an experimental physicist at the University of Chicago’s Institute of Molecular Engineering.
