1. Organic long persistent luminescence Long-lasting luminescence (LPL) material (a coating that is widely commercialized as "lighting in the dark") stores excitation energy in an excited state and slowly releases it in the form of light. Kind of energy. At present, most LPL materials are inorganic systems based on antimony-doped and antimony doped strontium aluminate (SrAl2O4) with a luminescence time of more than 10 hours. However, the system requires rare earth elements and temperatures above 1000 degrees Celsius in the manufacturing process, and the light scattering of the SrAl2O4 powder limits the transparency of the LPL coating. Kabe et al. demonstrated an organic LPL (OLPL) system of two simple organic molecules that are rare and easy to manufacture and can last for more than one hour at room temperature. Previous organic systems based on two-photon ionization required low temperatures and high excitation strength. In contrast, the OLPL system demonstrated by Kabe et al. is based on exciplexes of long-lived charge-separated complexes and can be excited by standard white LED sources, even at temperatures above 100 degrees Celsius. It glows for a long time. This OLPL system is transparent, soluble, flexible and tonable, opening up new applications for LPL in areas such as large-area flexible coatings, biomarkers, and textiles. In addition, the study of long-lived charge separation in this system can also promote understanding of various organic semiconductor devices. (Nature DOI: 10.1038/nature24010)
2. Printable organometallic perovskite capable large-area, low-dose X-ray imaging Medical X-ray imaging process requires digital flat panel detectors at low doses Run to reduce the risk of radiation affecting health. The solution-treated organic-inorganic hybrid perovskite has the characteristics of being an excellent candidate for the photoconductive layer of such sensitive detectors. However, since it has been difficult to prepare thick perovskite films (more than a few hundred micrometers) over a large area (the detector typically has 50 cm x 50 cm), such detectors have not yet been built on thin film transistor arrays. Kim et al. reported a synthetic approach based on solution (as opposed to conventional vacuum processing) to produce a printable polycrystalline perovskite, a multi-sharp, large-grained perovskite with single crystals. Similar morphology and optoelectronic properties. High sensitivity of up to 11 microcoulombs per air kerma per square centimeter (μC•mGyair-1cm-2) can be achieved with a 100 kV brem radiation source, which is more than the currently used amorphous selenium or tellurium doping The sensitivity achieved by the cesium iodide detector is at least an order of magnitude higher. Provides perovskite film and controls dark current and temporary charge carriers by embedding a 830 micron perovskite film and two additional polymer/perovskite composite intermediate layers into a conventional thin film transistor substrate The conformal interface between the transmitted electrodes, Kim et al. demonstrated their X-ray imaging. This solution-based perovskite detector enables low-dose X-ray imaging and can also be used on photoconductive devices for radiography, sensing and energy harvesting.

3. Spatiotemporal mode-locking in multimode fiber lasers The laser is based on the electromagnetic mode of its resonator (the feedback required to provide oscillation). Great progress has been made in controlling the longitudinal mode interaction of the laser in a single transverse mode. For example, the field of ultrafast science is based on lasers that lock many longitudinal modes together to form ultrashort optical pulses. However, the coherent superposition of the longitudinal and lateral modes of the laser has not received much attention. Wright et al. have shown that the modes and dispersions in fiber lasers can be offset by strong spatial and spectral filtering. This enables multiple lateral and longitudinal modes to be locked to produce ultrashort pulses with multiple spatiotemporal distributions. Therefore, multimode fiber lasers have opened up new directions for studying nonlinear wave propagation and its application capabilities. (Science DOI: 10.1126/science.aao0831)
4. A Fermi-degenerate three-dimensional optical lattice clock The Twilight lattice clock has the potential to simultaneously access millions of atoms with a 4×1017 hyperspectral quality factor. Previously, atomic interactions forced a compromise between clock stability and accuracy, the former benefiting from a large number of atoms, while the latter were affected by density-dependent frequency offsets. Campbell et al. demonstrated a scalable solution that uses the high correlation density of degenerate Fermi gas in a three-dimensional (3D) optical lattice to prevent in situ interaction transitions. They also demonstrated the problem of solving contact interactions, making their contribution to clock skew an order of magnitude lower than previous experiments. The synchronous clock alignment between the two regions of the three-dimensional lattice yields a measurement accuracy of 5 x 10-19 over a one hour average time.

5. Exciton Hall effect in monolayer MoS2 The spontaneous Hall effect driven by the quantum Behrian phase (as internal magnetic flux in the momentum space) exhibits the topological properties of quasiparticles and can be used Control information flow, such as spin and energy valley. Onga et al. reported a Hall effect of an exciton (a basic composite particle that determines the photoreaction of electrons and holes in a semiconductor). Through polarization-resolved photoluminescence mapping, Onga et al. directly observed the Hall effect of excitons in a single-layer MoS2 and the valley-selective spatial transport of excitons on the micrometer scale. It is found that the Hall angle of the exciton is larger than the Hall angle of a single electron in the single-layer MoS2, which means that the quantum transmission of the composite particle is significantly affected by its internal structure. The results not only reflect the fundamental problem of the Hall effect in composite particles, but also provide a way to explore exciton-based valley electronics in two-dimensional materials.

6. Field-free deterministic ultrafast creation of magnetic skyrmions by spin–orbit torques by spin-orbit torque. Magnetic sigmoids are external magnetic fields, stray field energy. The combination of higher order exchange interactions and Dzyaloshinskii-Moriya interaction (DMI) is stable. A recent single chiral scorpion whose motion is driven by rotational orbital torque is deterministic, which allows such a system to have an associated DMI for the application. In addition, the non-magnetic heavy metal layer can inject a vertical spin current having lateral spin polarization into the ferromagnetic layer by a rotating Hall effect. This allows the torque to be used to fully convert the magnetization in the out-of-plane magnetized ferromagnetic element, but this conversion is deterministic only in the presence of a field in a plane of symmetry breaking. Although spin-orbital torque results in domain nucleation in a continuous film and stochastic nucleation of a sigma in a track, there is no controllable formation of a single sigma at a particular location in an integrated device design. The actual method of reporting. Büttner et al. demonstrated that the sub-nanosecond spin orbit torque pulse can produce a single sigma in a custom position in the magnetic track (determined to use the same current path as used for the conversion operation). The role of DMI means that no external in-plane magnetic field is required. This embodiment utilizes defects that can be used as a Sigphire generator, such as shrinkage in a magnetic track. This concept applies to any track geometry, including 3D design. (Nature Nanotechnology DOI: 10.1038/NNANO.2017.178)
7. Towards phase-coherent caloritronics in superconducting circuits The rise of phase coherent thermoelectrics (from Latin calorie, ie heat) is based on the use of superconducting ordered parameter phase Poor to control the possibility of heat flow. The goal is to design and implement a thermal device that can control energy transfer in a manner that is close to the accuracy achieved by charge transfer of modern electronic components. This can be achieved by exploiting the inherent macroscopic coherence of the superconducting condensate, which can be manifested by the Josephson effect and the proximity effect. Fornieri et al. reviewed the latest experimental results obtained in the implementation of thermal interferometers and thermal potentiostats, and discussed some recommendations for heterogeneous nonlinear phase coherent thermoelectric devices, such as thermal transistors, solid state memories, phase coherent thermal separation. , microwave refrigerator, heat engine and heat valve. In addition to basic physics, these systems are expected to have a huge impact on many low-temperature microcircuits that require energy management, and may also lay the foundation for the foundation of electronic thermal logic.

8. Inner- and outer-wall sorting of double-walled carbon nanotubes Double-walled carbon nanotubes (DWCNTs) are composed of two coaxial single-walled nanotubes. The method can only achieve the selectivity of the outer wall electron type. Li et al. proposed a new classification technique that can classify DWCNTs into semiconductor (S) or metal (M) inner and outer wall electron types. Electron coupling between the inner and outer walls is typically used to alter the surfactant coating of each DWCNT type, and aqueous gels are used to separate them. Water system methods are commonly used to remove SWCNT species from raw materials and to prepare rich DWCNT fragments. These rich DWCNT fragments are then transferred to chlorobenzene or toluene by using the copolymer PFO-BPy to produce a combination of internal and external, namely: M@M, M@S, S@M and S@S. The high purity of these fragments has been verified by adsorption measurements, transmission electron microscopy, atomic force microscopy, and resonant Raman and high-density FET devices.
