Semiconductor Nanowires Could Double the Efficiency of Si Solar Cells

Posted by in categories: nanotechnology, solar power, space, sustainability

Gallium arsenide (GaAs) has long been touted as the best material for making high-efficiency solar cells because of its extraordinary light absorption and electrical characteristics. It has most notably been put to use in space solar panels.

These GaAs solar cells, however, are extremely pricey to produce resulting in a demand for methods that cut down on the material usage. That’s where nanowire structures come in. These elements can potentially enhance solar cell efficiency compared to standard planar solar cells while utilizing less material.

By using GaAs in the nanowire structures, the team of researchers has found a new way to make an ultrahigh power-per-weight ratio solar cell that is more than 10 times more efficient than any other solar cell.

Plans Of A Technocratic Elite: ‘The Great Reset’ Is Not A Conspiracy Theory

Posted by in categories: 3D printing, biotech/medical, genetics, information science, internet, nanotechnology, quantum physics, Ray Kurzweil, robotics/AI, singularity, transhumanism

According to Klaus Schwab, the founder and executive chair of the World Economic Forum (WEF), the 4-IR follows the first, second, and third Industrial Revolutions—the mechanical, electrical, and digital, respectively. The 4-IR builds on the digital revolution, but Schwab sees the 4-IR as an exponential takeoff and convergence of existing and emerging fields, including Big Data; artificial intelligence; machine learning; quantum computing; and genetics, nanotechnology, and robotics. The consequence is the merging of the physical, digital, and biological worlds. The blurring of these categories ultimately challenges the very ontologies by which we understand ourselves and the world, including “what it means to be human.”

The specific applications that make up the 4-R are too numerous and sundry to treat in full, but they include a ubiquitous internet, the internet of things, the internet of bodies, autonomous vehicles, smart cities, 3D printing, nanotechnology, biotechnology, materials science, energy storage, and more.

While Schwab and the WEF promote a particular vision for the 4-IR, the developments he announces are not his brainchildren, and there is nothing original about his formulations. Transhumanists and Singularitarians (or prophets of the technological singularity), such as Ray Kurzweil and many others, forecasted these and more revolutionary developments,. long before Schwab heralded them. The significance of Schwab and the WEF’s take on the new technological revolution is the attempt to harness it to a particular end, presumably “a fairer, greener future.”

A new dimension in magnetism and superconductivity is launched

Posted by in categories: biological, chemistry, nanotechnology, particle physics

An international team of scientists from Austria and Germany has launched a new paradigm in magnetism and superconductivity, putting effects of curvature, topology, and 3D geometry into the spotlight of next-decade research. The results are published in Advanced Materials.

Traditionally, the primary field in which curvature plays a pivotal role is the theory of general relativity. In recent years, however, the impact of curvilinear geometry has entered various disciplines, ranging from solid-state physics to soft-matter physics to chemistry and biology; and giving rise to a plethora of emerging domains, such as curvilinear cell biology, semiconductors, superfluidity, optics, plasmonics and 2D van der Waals materials. In modern magnetism, superconductivity and , extending nanostructures into the has become a major research avenue because of geometry-, curvature-and topology-induced phenomena. This approach provides a means to improve conventional functionalities and to launch novel functionalities by tailoring the curvature and 3D shape.

“In recent years, there have appeared experimental and theoretical works dealing with curvilinear and three-dimensional superconducting and (anti-)ferromagnetic nano-architectures. However, these studies originate from different scientific communities, resulting in the lack of knowledge transfer between such fundamental areas of condensed matter physics as magnetism and superconductivity,” says Oleksandr Dobrovolskiy, head of the SuperSpin Lab at the University of Vienna. “In our group, we lead projects in both these topical areas and it was the aim of our perspective article to build a ‘bridge’ between the magnetism and superconductivity communities, drawing attention to the conceptual aspects of how extension of structures into the third dimension and curvilinear geometry can modify existing and aid launching novel functionalities upon solid-state systems.”

How To Build a Real IRON MAN SUIT — Nanosuits & Neuromorphic Computing

Posted by in categories: biological, nanotechnology, robotics/AI, singularity, space travel

The future of Neuromorphic computing and nanotechnology enabling real life Nanosuits is already here according to several leading scientists in that field. Whether it’s the Nanosuit from Iron Man or from Crysis, the nanobots and brain computer interfaces which make those intelligent smart clothes up work in a very similar way.

Neuromorphic computing essentially involves assembling artificial neurons to function based on the principles of the human brain. It works on Spiking Neural Networks or SNNs, where each “neuron” sends independent signals to other neurons. It emulates natural neural networks that exist in biological brains.

Every day is a day closer to the Technological Singularity. Experience Robots learning to walk & think, humans flying to Mars and us finally merging with technology itself. And as all of that happens, we at AI News cover the absolute cutting edge best technology inventions of Humanity.

A superconducting silicon-photonic chip for quantum communication

Posted by in categories: computing, nanotechnology, quantum physics

Integrated quantum photonics (IQP) is a promising platform for realizing scalable and practical quantum information processing. Up to now, most of the demonstrations with IQP focus on improving the stability, quality, and complexity of experiments for traditional platforms based on bulk and fiber optical elements. A more demanding question is: “Are there experiments possible with IQP that are impossible with traditional technology?”

This question is answered affirmatively by a team led jointly by Xiao-Song Ma and Labao Zhang from Nanjing University, and Xinlun Cai from Sun Yat-sen University, China. As reported in Advanced Photonics, the team realizes quantum communication using a chip based on silicon photonics with a superconducting nanowire single-photon detector (SNSPD). The excellent performance of this chip allows them to realize optimal time-bin Bell state measurement and to significantly enhance the key rate in quantum communication.

The single photon detector is a key element for quantum key distribution (QKD) and highly desirable for photonic chip integration to realize practical and scalable quantum networks. By harnessing the unique high-speed feature of the optical waveguide-integrated SNSPD, the dead time of single-photon detection is reduced by more than an order of magnitude compared to the traditional normal-incidence SNSPD. This in turn allows the team to resolve one of the long-standing challenges in quantum optics: Optimal Bell-state measurement of time-bin encoded .

The highest amplification in tiny nanoscale devices

Posted by in category: nanotechnology

A team of researchers from the University of Florida, led by Dr. Philip Feng, in collaboration with Prof. Steven Shaw in Florida Institute of Technology, has now demonstrated extremely high-efficient mechanical signal amplification in nanoscale mechanical resonators operating at radio frequency. The devices employed in this research might be the tiniest mechanical resonators exhibiting amplification, and the gain achieved is the highest known for all mechanical devices reported to date.

The displacement is realized based on “parametric pumping or parametric amplification” of mechanical motion. Parametric amplification can be mainly achieved when a parameter of system is modulated by twice multiples of the . A simple example of parametric amplification is a child playing a swing. The child can periodically stand and squat twice in a single period of the swing to increase or “amplify” the swing amplitude without anyone helping to push.

The researchers have realized the parametric amplification in the tiny nanoscale devices. The nanoscale drumhead mechanical parametric amplifiers demonstrated in this research consist of an atomically thin two-dimensional semiconducting molybdenum disulfide (MoS2) membrane where the thickness of the drumheads is 0.7, 2.8, 7.7 nanometer with 1.8 micrometer in diameter and 0.0018–0.020 m3 in volume. The nanodrums are fabricated by transferring nanosheet exfoliated from bulk crystal over microcavities to make suspended atomically thin nanodrums.

5D Optical Storage: High-Speed Laser Writing Could Pack 500 Terabytes Into CD-Sized Glass Disc

Posted by in categories: computing, nanotechnology

Advances make high-density, 5D optical storage practical for long-term data archiving.

Researchers have developed a fast and energy-efficient laser-writing method for producing high-density nanostructures in silica glass. These tiny structures can be used for long-term five-dimensional (5D) optical data storage that is more than 10,000 times denser than Blue-Ray optical disc storage technology.

“Individuals and organizations are generating ever-larger datasets, creating the desperate need for more efficient forms of data storage with a high capacity, low energy consumption and long lifetime,” said doctoral researcher Yuhao Lei from the University of Southampton in the UK. “While cloud-based systems are designed more for temporary data, we believe that 5D data storage in glass could be useful for longer-term data storage for national archives, museums, libraries or private organizations.”
