Intriguing material property found in complex nanostructures could dissipate energy

Posted by in categories: engineering, nanotechnology

Researchers from The University of Texas at Austin and North Carolina State University have discovered, for the first time, a unique property in complex nanostructures that has thus far only been found in simple nanostructures. Additionally, they have unraveled the internal mechanics of the materials that makes this property possible.

In a new paper published this week in the Proceedings of the National Academy of Sciences, the researchers found these properties in oxide-based “nanolattices,” which are tiny, hollow materials, similar in structure to things like sea sponges.

“This has been seen before in simple nanostructures, like a nanowire, which is about 1,000 times thinner than a hair,” said Yong Zhu, a professor in the Department of Mechanical and Aerospace Engineering at NC State, and one of the lead authors on the paper. “But this is the first time we’ve seen it in a 3D .”

We have quantum computers—now Amazon and Harvard want a quantum internet

Posted by in categories: computing, internet, nanotechnology, quantum physics

Two big players in computing and research are trying to lay the groundwork for a future quantum internet.

Amazon Web Services (AWS) is teaming up with Harvard University to test and develop strategies for networking together quantum technologies. Their partnership was announced today, and is a continuation of AWS’ goals to create a communications channel between the quantum computers that it is also working on in parallel.

During the three-year research alliance, funding from Amazon will support research projects at Harvard that focus on quantum memory, integrated photonics, and quantum materials, and help upgrade infrastructure in Harvard’s Center for Nanoscale Systems.

New quantum algorithm solves critical quantum chemistry problem through adaptation along a geometric path

Posted by in categories: chemistry, information science, nanotechnology, quantum physics

A team of researchers from the U.S. Department of Energy’s (DOE) Brookhaven National Laboratory and Stony Brook University have devised a new quantum algorithm to compute the lowest energies of molecules at specific configurations during chemical reactions, including when their chemical bonds are broken. As described in Physical Review Research, compared to similar existing algorithms, including the team’s previous method, the new algorithm will significantly improve scientists’ ability to accurately and reliably calculate the potential energy surface in reacting molecules.

For this work, Deyu Lu, a Center for Functional Nanomaterials (CFN) physicist at Brookhaven Lab, worked with Tzu-Chieh Wei, an associate professor specializing in at the C.N. Yang Institute for Theoretical Physics at Stony Brook University, Qin Wu, a theorist at CFN, and Hongye Yu, a Ph.D. student at Stony Brook.

“Understanding the quantum mechanics of a molecule, how it behaves at an atomic level, can provide key insight into its chemical properties, like its stability and reactivity,” said Lu.

Nanotubes illuminate the way to living photovoltaics

“We put nanotubes inside of bacteria,” says Professor Ardemis Boghossian at EPFL’s School of Basic Sciences. “That doesn’t sound very exciting on the surface, but it’s actually a big deal. Researchers have been putting nanotubes in mammalian cells that use mechanisms like endocytosis, that are specific to those kinds of cells. Bacteria, on the other hand, don’t have these mechanisms and face additional challenges in getting particles through their tough exterior. Despite these barriers, we’ve managed to do it, and this has very exciting implications in terms of applications.”

Boghossian’s research focuses on interfacing artificial nanomaterials with biological constructs, including living cells. The resulting “nanobionic” technologies combine the advantages of both the living and non-living worlds. For years, her group has worked on the nanomaterial applications of single-walled carbon (SWCNTs), tubes of carbon atoms with fascinating mechanical and .

These properties make SWCNTs ideal for many novel applications in the field of nanobiotechnology. For example, SWCNTs have been placed inside to monitor their metabolisms using near-infrared imaging. The insertion of SWCNTs in mammalian cells has also led to new technologies for delivering therapeutic drugs to their intracellular targets, while in plant cells they have been used for genome editing. SWCNTs have also been implanted in living mice to demonstrate their ability to image biological tissue deep inside the body.

New energy harvesters show potential that fits like a glove

Posted by in categories: energy, nanotechnology

A group of University of Texas at Dallas researchers and their colleagues have made significant improvements to energy-harvesting yarns they invented called twistrons, which are made from carbon nanotubes and produce electricity when repeatedly stretched.

The researchers describe the improved twistrons and some potential applications of the technology in an article published in the July 7 print issue of Advanced Materials.

In a proof-of-principle experiment, Zhong Wang, Ph.D., lead author of the article and a research associate in the Alan G. MacDiarmid NanoTech Institute at UT Dallas, sewed the new twistron yarns into a glove. As someone wearing the glove formed different letters and phrases in American Sign Language, the hand gestures generated electricity.

Stretchable, self-powered bioelectronics mimic skin in form and function

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

Skin-like electronics could seamlessly integrate with the body for applications in health monitoring, medication therapy, implantable medical devices, and biological studies.

With the help of the Polsky Center for Entrepreneurship and Innovation, Sihong Wang, an assistant professor of molecular engineering at the University of Chicago’s Pritzker School of Molecular Engineering, has secured patents for the building blocks of these novel devices.

Drawing on innovation in the fields of semiconductor physics, solid mechanics, and energy sciences, this work includes the creation of stretchable polymer semiconductors and transistor arrays, which provide exceptional electrical performance, high semiconducting properties, and mechanical stretchability. Additionally, Wang has developed triboelectric nanogenerators as a new technology for harvesting energy from a user’s motion—and designed the associated energy storage process.

Scientists create nano-pipes that are two million times smaller than an ant

Posted by in categories: biotech/medical, nanotechnology

Explaining the potential of nanotubes further, one of the lead researchers and associate professor at Johns Hopkins University (JHU), Rebecca Schulman told IE, “Tinier plumbing might help us analyze individual molecules, which could help us make better drugs or enzymes, separate toxins, or even create better batteries by designing the conduits that ions flow through rather than using a porous material.”

She believes that although these technologies are still 10+ years away, their foundation is in things like nano-plumbing and being able to precisely measure and control the pipes the plumbing is made of.

Seaweed Suggested As Source of Anti-Tuberculosis Nanoparticles

Posted by in categories: biological, nanotechnology

Highlights and Key Developments of the Current Study

In this study, the researchers used the biological synthesis approach to analyze Sargassum polycystum aquatic extract to produce silver seaweed nanoparticles. Various spectroscopic methods, including absorption spectrophotometer (UV-VIS), scanning electron Microscope (SEM), and Fourier transforms infrared spectroscopy (FTIR), were applied to characterize the silver seaweed nanoparticles.

The antibacterial effects of seaweed nanoparticles against several microbial infections, including tuberculosis, were investigated. Zebrafish larvae were used to test the toxicity of the produced silver seaweed nanoparticles.
