"The so-called 'quantum thermodynamics' are currently under development," Roberto Serra, one of the researchers who carried out the study, told Phys.org. [40] A team of scientists from the Research Center "Fundamental Problems of Thermophysics and Mechanics," of Samara Polytech is engaged in the construction of new mathematical models and the search for methods for their study in relation to a wide range of local nonequilibrium transport processes in various physical systems. [39] Researchers at the Center for Soft and Living Matter, within the Institute for Basic Science (IBS, South Korea) found that the temperature increase caused by the probe beam could be utilized to generate a signal per se for detecting objects. [38] Scientists at the University of Würzburg have been able to boost current super-resolution microscopy by a novel tweak. [37] "We put the optical microscope under a microscope to achieve accuracy near the atomic scale," said NIST's Samuel Stavis, who served as the project leader for these efforts. [36] Researchers have designed an interferometer that works with magnetic quasiparticles called magnons, rather than photons as in conventional interferometers. [35] A technique to manipulate electrons with light could bring quantum computing up to room temperature. [34] The USTC Microcavity Research Group in the Key Laboratory of Quantum Information has perfected a 4-port, all-optically controlled non-reciprocal multifunctional photonic device based on a magnetic-field-free optomechanical resonator. [33] To address this technology gap, a team of engineers from the National University of Singapore (NUS) has developed an innovative microchip, named BATLESS, that can continue to operate even when the battery runs out of energy. [32] Stanford researchers have developed a water-based battery that could provide a cheap way to store wind or solar energy generated when the sun is shining and wind is blowing so it can be fed back into the electric grid and be redistributed when demand is high. [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]

Two-dimensional solar materials may offer a way to extract more energy from sunlight. By tuning the structure of a 2-D perovskite solar material, researchers from KAUST and the Georgia Institute of Technology have shown they can prolong the lifetime of highly energetic hot carriers generated by light striking the material.

For the first time, LEGO has been cooled to the lowest temperature possible in an experiment which reveals a new use for the popular toy. [25] Nothing in nature is known to hit the temperatures achieved in laboratories like CAL, which means the orbiting facility is regularly the coldest known spot in the universe. [24] There's an oddball in most families, but Rice University physicist Emilia Morosan has discovered an entire clan of eccentric compounds that could help explain the mysterious electronic and magnetic workings of other quantum materials engineers are eying for next-generation computers and electronics. [23] TU Wien (Vienna) and several research groups from China have now developed new ideas and implemented them in an experiment. [22] Light and high-frequency acoustic sound waves in a tiny glass structure can strongly couple to one another and perform a dance in step. [21] Researchers from the Moscow Institute of Physics and Technology, ETH Zurich, and Argonne National Laboratory, U.S, have described an extended quantum Maxwell's demon, a device locally violating the second law of thermodynamics in a system located one to five meters away from the demon. [20] "We've experimentally confirmed the connection between information in the classical case and the quantum case," Murch said, "and we're seeing this new effect of information loss." [19] It's well-known that when a quantum system is continuously measured, it freezes, i.e., it stops changing, which is due to a phenomenon called the quantum Zeno effect. [18] Physicists have extended one of the most prominent fluctuation theorems of classical stochastic thermodynamics, the Jarzynski equality, to quantum field theory. [17]

[30] Researchers have discovered three distinct variants of magnetic domain walls in the helimagnet iron germanium (FeGe). [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.

Researchers at MIT's Plasma Science and Fusion Center (PSFC) have now demonstrated how microwaves can be used to overcome barriers to steady-state tokamak operation. [42]
Plasma particle accelerators more powerful than existing machines could help probe some of the outstanding mysteries of our universe, as well as make leaps forward in cancer treatment and security scanning—all in a package that's around a thousandth of the size of current accelerators. [41]

To improve the life of the appliance and ensure the full production capacity, it is important to improve the protection of the contactor.
In the literature, due to the inability to accurately determine the type of arc-extinguishing of contactors with multiple open points[1-4]. Therefore, the researchers did not determine a reasonable ㄷ-type arc grid for enhancing the arc capacity.
This paper puts forward the problem of determining the electrodynamic force acting between the arc and the grid when the contact is open. The most reasonable ㄷ-type arc grid is determined by the ANSYS application program, and the method of increasing the service life of the mechanism is introduced.

In the prior literature, to improve the characteristics of the AC contactor, the structural dimension of the contact point was changed or the type of contact material was changed. This section introduces a method of improving the characteristics of contact including contact resistance and electrical wear by adding a rare earth element to the Ag-Cd0 contact point, which is currently used as an AC contactor.

In order to improve wear resistance of components such as screws with severe friction-wear, microstructure and wear resistance of Fe-C-Cr-Mo-V-Ti-N hardfacing metal were investigated. Ferroalloys added into the coating of hardfacing electrodes were nitrided jointly. The microstructure and wear resistance of hardfacing metals were characterized by means of X-ray diffraction (XRD), optical microscopy (OM), field emission scanning electron microscope (FESEM) and energy dispersive X-ray spectrometry (EDS). In addition, Factsage 7.0 software was used to calculate the equilibrium phase diagram of the hardfacing metals. The results show that the hardfacing layers mainly consist of martensite, austenite, α-Fe, M23C6, M7C3, V8C7-type carbides and MX-type complex precipitations (M= V, Ti; X=C, N). The Fe-C-Cr-Mo-V-Ti-N hardfacing layer possesses 1.5 times higher wear resistance than cladding layers without nitrides.
