Internet of Things Devices Security

Authors: George Rajna
Comments: 98 Pages.

As Americans increasingly buy and install smart devices in their homes, all those cheap interconnected devices create new security problems for individuals and society as a whole. [55] An international team of researchers led by ANU is helping to build a safe data superhighway for the highly anticipated quantum internet, which promises a new era of artificial intelligence and ultra-secure communication. [54] For the first time, researchers have succeeded in producing what are known as spin wave overtones. The technology paves the way for increasing the data transmission rate of wireless communication. [53] "This research highlights the cutting-edge research being done at WVU, and we are very excited to see their work appear in the very high-profile journal Nature Communications." [52]

Holographic Color Printing

Authors: George Rajna
Comments: 62 Pages.

Researchers from the Singapore University of Technology and Design (SUTD) have invented a new type of anti-counterfeiting technology called holographic colour prints for securing important documents such as identity cards, passports and banknotes. [36] Holography is a powerful tool that can reconstruct wavefronts of light and combine the fundamental wave properties of amplitude, phase, polarization, wave vector and frequency. [35] Physicist Artem Rudenko from Kansas State University and his colleagues pondered how to improve the images of viruses and microparticles that scientists get from X-rays. [34] A team of materials scientists from Penn State, Cornell and Argonne National Laboratory have, for the first time, visualized the 3-D atomic and electron density structure of the most complex perovskite crystal structure system decoded to date. [33] Hydrogen-powered electronics, travel, and more may be a step closer thanks to the work of a collaborative team of scientists in Japan. [32]

Photonic Memory Devices

Authors: George Rajna
Comments: 49 Pages.

Researchers of the Institute of Photonic Integration of the Eindhoven University of Technology (TU/e) have developed a 'hybrid technology' which shows the advantages of both light and magnetic hard drives. [35] Researchers at Friedrich-Alexander-Universität Erlangen-Nürnberg (FAU) have developed a simple yet accurate method for finding defects in the latest generation of silicon carbide transistors. [34] In 2017, University of Utah physicist Valy Vardeny called perovskite a "miracle material" for an emerging field of next-generation electronics, called spintronics, and he's standing by that assertion.

Overtones Faster Data Communication

Authors: George Rajna
Comments: 93 Pages.

For the first time, researchers have succeeded in producing what are known as spin wave overtones. The technology paves the way for increasing the data transmission rate of wireless communication. [53] "This research highlights the cutting-edge research being done at WVU, and we are very excited to see their work appear in the very high-profile journal Nature Communications." [52] By constructing a hybrid device made from two different types of qubit—the fundamental computing element of quantum computers—they have created a device that can be quickly initialized and read out, and that simultaneously maintains high control fidelity. [51] Researchers have demonstrated that an amoeba—a single-celled organism consisting mostly of gelatinous protoplasm—has unique computing abilities that may one day offer a competitive alternative to the methods used by conventional computers. [50] For the first time, researchers have used tiny gears made of germanium to generate a vortex of twisted light that turns around its axis of travel much like a corkscrew. [49] Physical systems with discrete energy levels are ubiquitous in nature and form fundamental building blocks of quantum technology. [48]

Information Processing Reimagining

Authors: George Rajna
Comments: 91 Pages.

"This research highlights the cutting-edge research being done at WVU, and we are very excited to see their work appear in the very high-profile journal Nature Communications." [52] By constructing a hybrid device made from two different types of qubit-the fundamental computing element of quantum computers-they have created a device that can be quickly initialized and read out, and that simultaneously maintains high control fidelity. [51] Researchers have demonstrated that an amoeba-a single-celled organism consisting mostly of gelatinous protoplasm-has unique computing abilities that may one day offer a competitive alternative to the methods used by conventional computers. [50] For the first time, researchers have used tiny gears made of germanium to generate a vortex of twisted light that turns around its axis of travel much like a corkscrew. [49] Physical systems with discrete energy levels are ubiquitous in nature and form fundamental building blocks of quantum technology. [48] In a similar vein, scientists are working to create twisting helical electromagnetic waves whose curvature allows more accurate imaging of the magnetic properties of different materials at the atomic level and could possibly lead to the development of future devices. [47] In a recent study, materials scientists Guojin Liang and his coworkers at the Department of Materials Science and Engineering, City University of Hong Kong, have developed a self-healing, electroluminescent (EL) device that can repair or heal itself after damage. [46] A team of researchers based at The University of Manchester have found a low cost method for producing graphene printed electronics, which significantly speeds up and reduces the cost of conductive graphene inks. [45] Graphene-based computer components that can deal in terahertz "could be used, not in a normal Macintosh or PC, but perhaps in very advanced computers with high processing rates," Ozaki says. This 2-D material could also be used to make extremely high-speed nanodevices, he adds. [44]

Real Time Blockchains

Authors: George Rajna
Comments: 102 Pages.

Blockchains promise widescale open Internet applications that are organised decentrally, but this comes at the price of slow performance for every transaction processed by the system. [60] The ability to precisely control the interactions of light and matter at the nanoscale could help such a network transmit larger amounts of data more quickly and securely than an electrical network. [59] Researchers in Italy have demonstrated the feasibility of quantum communications between high-orbiting global navigation satellites and a ground station, with an exchange at the single photon level over a distance of 20,000km. [58] Living cells, regardless of the type, can be kept around for a long time and because they move constantly, can be photographed repeatedly to create new encryption keys. [57] A new electronic device can developed at the University of Michigan can directly model the behaviors of a synapse, which is a connection between two neurons. [56] "The atom-scale devices we are developing create a new basis for HYPERLINK "https://phys.org/tags/computer/" computer electronics that will be able to run at least 100 times faster or operate at the same speed as today but using 100 times less energy," continued Wolkow.
