Lab-spun sponges form perfect scaffolds for growing skin cells to heal wounds

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

A new technique for electrospinning sponges has allowed scientists from the University of Surrey to directly produce 3D scaffolds—on which skin grafts could be grown from the patient’s own skin.

Electrospinning is a technique that electrifies droplets of liquid to form fibers from plastics. Previously, scientists had only been able to make 2D films. This is the first time anybody has electro-spun a 3D structure directly and on-demand so that it can be produced to scale. The research is published in the journal Nanomaterials.

Chloe Howard, from Surrey’s School of Computer Science and Electronic Engineering, said, After spinning these scaffolds, we grew skin cells on them. Seven days later, they were twice as viable as cells grown on 2D films or mats. They even did better than cells grown on plasma-treated polystyrene—previously, the gold standard. They were very happy cells on our 3D scaffolds.

Fundamental equation for superconducting quantum bits revised

Posted by in categories: computing, information science, quantum physics

Physicists from Forschungszentrum Jülich and the Karlsruhe Institute of Technology have uncovered that Josephson tunnel junctions—the fundamental building blocks of superconducting quantum computers—are more complex than previously thought.

Just like overtones in a , harmonics are superimposed on the fundamental mode. As a consequence, corrections may lead to quantum bits that are two to seven times more stable. The researchers support their findings with experimental evidence from multiple laboratories across the globe, including the University of Cologne, Ecole Normale Supérieure in Paris, and IBM Quantum in New York.

It all started in 2019, when Dr. Dennis Willsch and Dennis Rieger—two Ph.D. students from FZJ and KIT at the time and joint first authors of a new paper published in Nature Physics —were having a hard time understanding their experiments using the standard model for Josephson tunnel junctions. This model had won Brian Josephson the Nobel Prize in Physics in 1973.

Lithography Leader ASML Hyper-NA is Next Step in Smaller Transistors. 2.9X Density

Posted by in category: computing

High NA EUV is the next step in smaller transistors. Like NXE systems, it uses EUV light to print tiny features on silicon wafers. And by turning the NA knob, we deliver even better resolution: The new platform, known as EXE, offers chipmakers a CD (critical dimension) of 8 nm. That means they can print transistors 1.7 times smaller – and therefore achieve transistor densities 2.9 times higher – than they can with NXE systems.

EUV lithography allowed us to make a big turn of the wavelength knob. It uses 13.5 nm light, compared to 193 nm for the highest-resolution DUV systems. The first pre-production EUV lithography platform, the NXE, shipped in 2010 and delivered a drop in CD (critical dimension) from more than 30 nm in DUV down to 13 nm with EUV.

Quantum Computing Breakthrough: New Fusion of Materials Has All the Components Required for a Unique Type of Superconductivity

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

A new fusion of materials, each with special electrical properties, has all the components required for a unique type of superconductivity that could provide the basis for more robust quantum computing. The new combination of materials, created by a team led by researchers at Penn State, could also provide a platform to explore physical behaviors similar to those of mysterious, theoretical particles known as chiral Majoranas, which could be another promising component for quantum computing.

The new study was recently published in the journal Science. The work describes how the researchers combined the two magnetic materials in what they called a critical step toward realizing the emergent interfacial superconductivity, which they are currently working toward.

Physicists Develop New Significantly More Efficient Solar Cell

Posted by in categories: computing, physics, solar power, sustainability

Physicists at Paderborn University have enhanced solar cell efficiency significantly using tetracene, an organic material, based on complex computer simulations. They discovered that defects at the tetracene-silicon interface boost energy transfer, promising a new solar cell design with drastically improved performance.

Physicists at Paderborn University have used complex computer simulations to create a novel solar cell design that boasts substantially higher efficiency than existing options. The enhancement in performance is attributed to a slender coating of an organic compound named tetracene. The results have recently been published in the renowned journal Physical Review Letters.

“The annual energy of solar radiation on Earth amounts to over one trillion kilowatt-hours and thus exceeds the global energy demand by more than 5,000 times. Photovoltaics, i.e. the generation of electricity from sunlight, therefore offers a large and still largely untapped potential for the supply of clean and renewable energy. Silicon solar cells used for this purpose currently dominate the market, but have efficiency limits,” explains Prof Dr Wolf Gero Schmidt, physicist and Dean of the Faculty of Natural Sciences at Paderborn University. One reason for this is that some of the energy from short-wave radiation is not converted into electricity, but into unwanted heat.
