Applications of the amniotic membrane in tissue engineering and regeneration: the hundred-year challenge

Posted by in categories: bioengineering, biotech/medical, life extension, nanotechnology

The amniotic membrane (Amnio-M) has various applications in regenerative medicine. It acts as a highly biocompatible natural scaffold and as a source of several types of stem cells and potent growth factors. It also serves as an effective nano-reservoir for drug delivery, thanks to its high entrapment properties. Over the past century, the use of the Amnio-M in the clinic has evolved from a simple sheet for topical applications for skin and corneal repair into more advanced forms, such as micronized dehydrated membrane, amniotic cytokine extract, and solubilized powder injections to regenerate muscles, cartilage, and tendons. This review highlights the development of the Amnio-M over the years and the implication of new and emerging nanotechnology to support expanding its use for tissue engineering and clinical applications.

Meta says its metaverse ambitions won’t be possible without better cellular networks

Posted by in category: habitats

Meta, formerly Facebook, has said that its grand ambition of building the ultimate “metaverse” won’t be possible if there aren’t drastic improvements in today’s telecoms networks.

The metaverse is a buzzword that’s being hyped up as the next big thing in tech. Broadly speaking, the concept refers to a seamless virtual world where people can work, shop and play with their colleagues, friends and family.

Dan Rabinovitsj, VP of connectivity at Meta, told CNBC at the Mobile World Congress tech event Monday that home networks and cellular networks aren’t yet ready for the metaverse.

Discovered: An easier way to create ‘flexible diamonds’

Posted by in categories: chemistry, materials

As hard as diamond and as flexible as plastic, highly sought-after diamond nanothreads would be poised to revolutionize our world—if they weren’t so difficult to make.

Recently, a team of scientists led by Carnegie’s Samuel Dunning and Timothy Strobel developed an original technique that predicts and guides the ordered creation of strong, yet flexible, , surmounting several existing challenges. The innovation will make it easier for scientists to synthesize the nanothreads—an important step toward applying the material to practical problems in the future. The work was recently published in the Journal of the American Chemical Society.

Diamond nanothreads are ultra-thin, one-dimensional carbon chains, tens of thousands of times thinner than a human hair. They are often created by compressing smaller carbon-based rings together to form the same type of bond that makes the hardest mineral on our planet.

Small, diamond-based quantum computers could be in our hands within five years

Posted by in categories: computing, quantum physics

Circa 2021


Small, affordable, ‘plug-and-play’ quantum computing is one step closer. An Australian startup has won $13 million to make its diamond-based computing cores shine. Now it needs to grow.

ANU research spinoff Quantum Brilliance has found a way to use synthetic diamonds to drive quantum calculations. Now it’s on a five-year quest to produce commercially viable Quantum Accelerators. The goal is a card capable of being plugged into any existing computer system similar to the way graphics cards are now.

Quantum Friction Explains Water’s Freaky Flow

Posted by in categories: nanotechnology, particle physics, quantum physics

Schran agrees. “This new mechanism of friction is definitely very interesting and exciting,” he says. “But what is missing in my opinion, is a clear benchmark measurement.” Quantifying, for instance, how friction changes based on water’s interaction with single versus multiple layers of carbon atoms could go a long way to fully verifying the new theory, which predicts that greater numbers of electrons in the multilayered carbon will boost friction.

The study team is already progressing along this path and dreaming of what lies beyond. They are hoping to eventually test their theory with flowing liquids other than water, and nanotubes composed of elements besides carbon. In such cases, molecules in the liquid and the electrons within nanotube walls would follow different patterns of interaction, possibly leading to changes in the degree of quantum friction. Lydéric Bocquet says that it may even be possible to control the amount of friction a flowing liquid experiences by constructing nanotubes with electron behavior explicitly in mind.

The new study sets the stage for years of complex exploration by experimental and theoretical physicists alike and, according to Kavokine, also signals a fundamental shift in how physicists should think about friction. “Physicists have long thought that it is different at the nanoscale, but this difference was not so obvious to find and describe,” he says. “They were dreaming about some quantum behavior arising at these scales—and now we have shown how it does.”
