Time Crystals Experiment

Authors: George Rajna
Comments: 51 Pages.

Dreamt up by the physics Nobel laureate Frank Wilczek in 2012, the notion of " time crystals " is now moving from theory to experiment – and could also lead to applications such as a new kind of atomic clock. [25] Yale physicists have uncovered hints of a time crystal—a form of matter that "ticks" when exposed to an electromagnetic pulse—in the last place they expected: a crystal you might find in a child's toy. [24] The research shows that concentrated electrolytes in solution affect hydrogen bonding, ion interactions, and coordination geometries in currently unpredictable ways. [23] An exotic state of matter that is dazzling scientists with its electrical properties, can also exhibit unusual optical properties, as shown in a theoretical study by researchers at A*STAR. [22] The breakthrough was made in the lab of Andrea Alù, director of the ASRC's Photonics Initiative. Alù and his colleagues from The City College of New York, University of Texas at Austin and Tel Aviv University were inspired by the seminal work of three British researchers who won the 2016 Noble Prize in Physics for their work, which teased out that particular properties of matter (such as electrical conductivity) can be preserved in certain materials despite continuous changes in the matter's form or shape. [21] Researchers at the University of Illinois at Urbana-Champaign have developed a new technology for switching heat flows 'on' or 'off'. [20] Thermoelectric materials can use thermal differences to generate electricity. Now there is an inexpensive and environmentally friendly way of producing them with the simplest tools: a pencil, photocopy paper, and conductive paint. [19] A team of researchers with the University of California and SRI International has developed a new type of cooling device that is both portable and efficient. [18] Thermal conductivity is one of the most crucial physical properties of matter when it comes to understanding heat transport, hydrodynamic evolution and energy balance in systems ranging from astrophysical objects to fusion plasmas. [17] Researchers from the Theory Department of the MPSD have realized the control of thermal and electrical currents in nanoscale devices by means of quantum local observations. [16]

Liquid Metal Heartbeat

Authors: George Rajna
Comments: 40 Pages.

In a breakthrough discovery, University of Wollongong (UOW) researchers have created a "heartbeat" effect in liquid metal, causing the metal to pulse rhythmically in a manner similar to a beating heart. [26] Collective spin oscillations have been spotted for the first time in an ultracold atomic gas. [25] Four decades after it was predicted, scientist create a skyrmion, and take one step towards efficient nuclear fusion. [24] While standard quantum hardware entangles particles in two states, the team has found a way to generate and entangle pairs of particles that each has 15 states. [23] An exotic state of matter that is dazzling scientists with its electrical properties, can also exhibit unusual optical properties, as shown in a theoretical study by researchers at A*STAR.

Rare Isotope Beams

Authors: George Rajna
Comments: 37 Pages.

Researchers from Michigan State University and the RIKEN Nishina Center in Japan discovered eight new rare isotopes of the elements phosphorus, sulfur, chlorine, argon, potassium, scandium and, most importantly, calcium. [27] Physics textbooks might have to be updated now that an international research team has found evidence of an unexpected transition in the structure of atomic nuclei. [26] The group led by Fabrizio Carbone at EPFL and international colleagues have used ultrafast transmission electron microscopy to take attosecond energy-momentum resolved snapshots (1 attosecond = 10-18 or quintillionths of a second) of a free-electron wave function. [25] Now, physicists are working toward getting their first CT scans of the inner workings of the nucleus. [24] The process of the sticking together of quarks, called hadronisation, is still poorly understood. [23] In experimental campaigns using the OMEGA EP laser at (MIT) researchers took radiographs of the shock front, similar to the X-ray radiology in hospitals with protons instead of X-rays. [22] Researchers generate proton beams using a combination of nanoparticles and laser light. [21] Devices based on light, rather than electrons, could revolutionize the speed and security of our future computers. However, one of the major challenges in today's physics is the design of photonic devices, able to transport and switch light through circuits in a stable way. [20] Researchers characterize the rotational jiggling of an optically levitated nanoparticle, showing how this motion could be cooled to its quantum ground state. [19] Researchers have created quantum states of light whose noise level has been " squeezed " to a record low. [18] An elliptical light beam in a nonlinear optical medium pumped by " twisted light " can rotate like an electron around a magnetic field. [17]

Molecular Mechanics and Quantum Chemical Study on Sites of Action of Sanguinarine Using Vibrational Spectroscopy Based on Molecular Mechanics and Quantum Chemical Calculations

Authors: Ricardo Gobato, Alireza Heidari
Comments: 23 Pages. Malaysian Journal of Chemistry, 2018, Vol. 20(1), 1 – 23. Key words: Density functional theory; Hartree-Fock, Møller-Plesset; molecular geometry; quantum chemistry, PM3; sanguinarine. Received: March 2018; Accepted: April 2018.

Sanguinarine is an alkaloid studied in the treatment of cancer cell proliferation. Found in several plants with Argemone mexicana Linn, the plant is used in traditional medicine from several countries with Mexico and India in the natural treatment of wounds, conjunctivitis and as hallucinogen. Due to these studies of this alkaloid, a study was made on a molecular structure of the sanguinarine, through quantum chemistry, via computational methods such as molecular mechanics, PM3, Hartree-Fock, density functional theory and Møller-Plesset. The main site of molecular interaction was determined to be the hydrogen atoms. This has a strong antioxidant potential in its structure. It probably interacts with free radicals reducing their carcinogenic effect on cells. A study of the infrared spectrum complemented the paper.

Second Skyrmion Phase

Authors: George Rajna
Comments: 53 Pages.

A team of researchers affiliated with several institutions in Germany has found a second skyrmion phase in a sample of Cu2OSeO3. [32] Unique physical properties of these "magic knots" might help to satisfy demand for IT power and storage using a fraction of the energy. [31] A skyrmion is the magnetic version of a tornado which is obtained by replacing the air parcels that make up the tornado by magnetic spins, and by scaling the system down to the nanometre scale. [30] A new material created by Oregon State University researchers is a key step toward the next generation of supercomputers. [29] Magnetic materials that form helical structures—coiled shapes comparable to a spiral staircase or the double helix strands of a DNA molecule—occasionally exhibit exotic behavior that could improve information processing in hard drives and other digital devices. [28] In a new study, researchers have designed "invisible" magnetic sensors—sensors that are magnetically invisible so that they can still detect but do not distort the surrounding magnetic fields. [27] At Carnegie Mellon University, Materials Science and Engineering Professor Mike McHenry and his research group are developing metal amorphous nanocomposite materials (MANC), or magnetic materials whose nanocrystals have been grown out of an amorphous matrix to create a two phase magnetic material that exploits both the attractive magnetic inductions of the nanocrystals and the large electrical resistance of a metallic glass. [26] The search and manipulation of novel properties emerging from the quantum nature of matter could lead to next-generation electronics and quantum computers. [25] A research team from Lab) has found the first evidence that a shaking motion in the structure of an atomically thin (2-D) material possesses a naturally occurring circular rotation. [24]

Atomic Movie of Melting Gold

Authors: George Rajna
Comments: 61 Pages.

Researchers at the Department of Energy's SLAC National Accelerator Laboratory have recorded the most detailed atomic movie of gold melting after being blasted by laser light. [38] A team at TU Wien now has the proof behind the speculations that water molecules can form complex bridge-like structures when they accumulate on mineral surfaces. [37] Liquid water sustains life on earth, but its physical properties remain mysterious among scientific researchers. [36] Researchers from the University of Houston and the California Institute of Technology have reported an inexpensive hybrid catalyst capable of splitting water to produce hydrogen, suitable for large-scale commercialization. [35] Scientists at the University of Alberta have applied a machine learning technique using artificial intelligence to perfect and automate atomic-scale manufacturing, something which has never been done before. [34] Chemist Dr. Lars Borchardt and his team at TU Dresden recently achieved a huge breakthrough in the synthesis of nanographenes. [33] Using graphene as a light-sensitive material for light detectors offers significant improvements with respect to materials being used nowadays. [32] The precision of measuring nanoscopic structures could be substantially improved, thanks to research involving the University of Warwick and QuantIC researchers at the University of Glasgow and Heriot Watt University into optical sensing. [31] Researchers at AMOLF and the University of Texas have circumvented this problem with a vibrating glass ring that interacts with light. They thus created a microscale circulator that directionally routes light on an optical chip without using magnets. [30] Researchers have discovered three distinct variants of magnetic domain walls in the helimagnet iron germanium (FeGe).

A team of physicists from the University of Nebraska-Lincoln, Stanford University and Europe has captured the clearest glimpse yet of a photochemical reaction—the type of light-fueled molecular transformations responsible for photosynthesis, vision and the ozone layer.

Laser on Earth's Core

Authors: George Rajna
Comments: 52 Pages.

Scientists have discovered fresh insights into the metallic core at the centre of our planet. [32] Solar energy is clean and abundant. But when the sun isn't shining, you must store the energy in batteries or through a process called photocatalysis—in which solar energy is used to make fuels. [31] An international team of scientists, including NUST MISIS's Professor Gotthard Seifert, has made an important step toward the control of excitonic effects in two-dimensional van der Waals heterostructures. [30] Carbon nanotubes – cylindrical formations of carbon atoms with incredible strength and electrical conductivity – hold great promise for creating new micron-scale low-power electronic devices. [29] An electrically conductive hydrogel that takes stretchability, self-healing and strain sensitivity to new limits has been developed at KAUST. [28] UCLA scientists and engineers have developed a new process for assembling semiconductor devices. [27] A new experiment that tests the limit of how large an object can be before it ceases to behave quantum mechanically has been proposed by physicists in the UK and India. [26] Phonons are discrete units of vibrational energy predicted by quantum mechanics that correspond to collective oscillations of atoms inside a molecule or a crystal. [25] This achievement is considered as an important landmark for the realization of practical application of photon upconversion technology. [24] Considerable interest in new single-photon detector technologies has been scaling in this past decade. [23] Engineers develop key mathematical formula for driving quantum experiments. [22] Physicists are developing quantum simulators, to help solve problems that are beyond the reach of conventional computers. [21]

Swimming Bacteria Reduce Viscosity

Authors: George Rajna
Comments: 60 Pages.

Swimming bacteria can reduce the viscosity of ordinary liquids like water and make them flow more easily, sometimes down to the point where the viscosity becomes zero: the flow is then frictionless.

Using the Quantum Chemistry for Genesis of a Nano Biomembrane with a Combination of the Elements Be, Li, Se, Si, C and H

Authors: Ricardo Gobato, Alireza Heidari, Abhijit Mitra
Comments: 15 Pages. DOI: 10.13140/RG.2.2.22315.75047

Preliminary bibliographic studies did not reveal any works with characteristics studied here. With this arrangement of atoms and employees with such goals. Going beyond with imagination using quantum chemistry in calculations to obtain probable one new bio-inorganic molecule, to the Genesis of a biomembrane with a combination of the elements Be, Li, Se, Si, C and H. After calculation a bio-inorganic seed molecule from the previous combination, it led to the search for a molecule that could carry the structure of a membrane. From a simple molecular dynamics, through classical calculations, the structure of the molecule was stabilized. An advanced study of quantum chemistry using ab initio, HF (Hartree-Fock) method in various basis is applied and the expectation of the stabilization of the Genesis of this bio-inorganic was promising. The calculations made so far admit a seed molecule at this stage of the quantum calculations of the arrangement of the elements we have chosen, obtaining a highly reactive molecule with the shape polar-apolar-polar. Calculations obtained in the ab initio RHF method, on the set of basis used, indicate that the simulated molecule,C_13H_20BeLi_2SeSi, is acceptable by quantum chemistry. Its structure has polarity at its ends, having the characteristic polar-apolar-polar. Even using a simple base set the polar-apolar-polar characteristic is predominant. The set of basis used that have the best compatible, more precise results are CC-pVTZ and 6-311G(3df,3pd). In the CC-pVTZ base set, the charge density in relation to 6-311G (3df, 3pd) is 50% lower. The structure of the bio-inorganic seed molecule for a biomembrane genesis that challenge the current concepts of a protective mantle structure of a cell such as biomenbrane to date is promising, challenging. Leaving to the biochemists their experimental synthesis.
