Researchers invent new way to stretch diamond for better quantum bits

Posted by in categories: engineering, quantum physics

A future quantum network may become less of a stretch thanks to researchers at the University of Chicago, Argonne National Laboratory and Cambridge University.

A team of researchers announced a breakthrough in quantum network engineering. By “stretching” thin films of diamond, they created that can operate with significantly reduced equipment and expense. The change also makes the bits easier to control.

The researchers hope the findings, published Nov. 29 in Physical Review X, can make future quantum networks more feasible.

Researchers triple carbon nanotube yield for LEDs, solar cells, flexible and transparent electronics

Posted by in categories: biotech/medical, chemistry, engineering, nanotechnology, solar power

Skoltech scientists have found a way to improve the most widely used technology for producing single-walled carbon nanotube films—a promising material for solar cells, LEDs, flexible and transparent electronics, smart textiles, medical imaging, toxic gas detectors, filtration systems, and more. By adding hydrogen gas along with carbon monoxide to the reaction chamber, the team managed to almost triple carbon nanotube yield compared with when other growth promoters are used, without compromising quality.

Until now, low yield has been the bottleneck limiting the potential of that manufacturing technology, otherwise known for high product quality. The study has been published in the Chemical Engineering Journal.

Although that is not how they’re really made, conceptually, nanotubes are a form of carbon where sheets of atoms in a honeycomb arrangement—known as graphene—are seamlessly rolled into hollow cylinders.

Researchers develop first-of-its-kind woven material made entirely from flexible organic crystals

Posted by in categories: engineering, space travel

Applying simple, ancient weaving techniques to newly recognized properties of organic crystals, researchers with the Smart Materials Lab (SML) and the Center for Smart Engineering Materials (CSEM) at NYU Abu Dhabi (NYUAD) have, for the first time, developed a unique form of woven “textile.” These new fabric patches expand one-dimensional crystals into flexible, integrated, two-dimensional planar structures that are incredibly strong—some 20 times stronger than the original crystals—and resistant to low temperatures.

These traits give them a host of exciting potential applications, including in that range from sensing devices to optical arrays, as well as in extreme conditions such as low temperatures encountered in space exploration.

In the paper titled “Woven Organic Crystals” published in the journal Nature Communications, Panče Naumov, NYUAD Professor of Chemistry and Director of the CSEM, and colleagues from Jilin University demonstrate that organic crystal can be simply woven into flexible and robust patches with plain, twill, and satin textures.

Awesome photo of Earth and the Moon captured by Orion from deep space

Posted by in categories: engineering, space travel

In an extraordinary feat of engineering and international collaboration, the Orion spacecraft, a part of NASA’s Artemis I mission, has achieved a remarkable milestone in space exploration. The spacecraft ventured some 267,000 miles from Earth and roughly 40,000 miles from the Moon, surpassing the distance record set by the Apollo 13 mission over half a century ago.

In this photo, the Orion capsule, along with the Earth and the Moon, appeared to be posing for a ‘family portrait.’ This iconic image marks a pivotal moment in the mission’s journey, symbolizing the culmination of years of meticulous planning and execution.

Orion’s journey from Earth began a year ago, on November 16, 2022, when NASA’s mega Moon rocket, the Space Launch System, lifted off from the Kennedy Space Center in Florida, USA. The uncrewed Orion spacecraft was placed into Earth orbit, marking the beginning of a new era in lunar exploration.

CRISPR-powered optothermal nanotweezers

Posted by in categories: biotech/medical, engineering, nanotechnology

Optothermal nanotweezers are an innovative optical design method that has revolutionized classical optical techniques to capture a broad range of nanoparticles. While the optothermal temperature field can be employed for in situ regulation of nanoparticles, challenges remain in identifying their potential for regulating bionanoparticles.

To observe the synergistic effects of optothermal manipulation and Clustered Regularly Interspaced Short Palindromic Repeats (CRISPR)-based biodetection, the researchers developed a combination of CRISPR-powered optothermal nanotweezers abbreviated as CRONT.

In a new report in Light: Science & Applications, Jiajie Chen and a research team in optoelectronics engineering, , and physics, accomplished this by harnessing diffusiophoresis and thermo-osmotic flows for optothermal excitation by successfully enriching DNA functionalized gold nanoparticles, CRISPR-associated proteins, and DNA strands.

Scientists 3D-Print Hair Follicles in Lab-Grown Skin

Posted by in categories: 3D printing, bioprinting, biotech/medical, chemistry, engineering, life extension

The technique represents an important step in engineering skin grafts, drug testing. A team led by scientists at Rensselaer Polytechnic Institute has 3D-printed hair follicles in human skin tissue cultured in the lab. This marks the first time researchers have used the technology to generate hair follicles, which play an important role in skin healing and function.

The finding, published in the journal Science Advances, has potential applications in regenerative medicine and drug testing, though engineering skin grafts that grow hair are still several years away.

“Our work is a proof-of-concept that hair follicle structures can be created in a highly precise, reproducible way using 3D-bioprinting. This kind of automated process is needed to make future biomanufacturing of skin possible,” said Pankaj Karande, Ph.D., an associate professor of chemical and biological engineering and a member of Rensselaer’s Shirley Ann Jackson, Ph.D. Center for Biotechnology and Interdisciplinary Studies, who led the study.

Tesla ‘fully open source’ original Roadster design and engineering, releases R&D docs

Posted by in categories: engineering, transportation

Tesla has made its original Roadster design and engineering “fully open source” and released R&D documents accessible to everyone.

The original Tesla Roadster hasn’t been in production for more than a decade now, and we are still waiting for the new generation that was unveiled all the way back in 2017 and has been delayed several times since.

The vehicle has become quite rare.
