The perovskite films were analysed by X-ray diffraction, UV/Vis absorption spectroscopy and Scanning electron microscope and the obtained solar cell devices were characterized by current–voltage curve measurements. The overall efficiency of the solar cells fabricated with a perovskite film using 0.5 mg.L-1 additive enhanced up to 2 % in comparison to those of non-additive ones. lắp mạng viettel tphcm It requires CXOs to build a discipline that connects the broad-strokes, big-picture enterprise view of value with the nuanced complexities of digital transformation. First, adopt a wide-angle perspective to create a link between enterprise value and new digital investments. This is a major gap that exists today in understanding the total value from a future tech investment.

In this research, we used first principles methods with density functional theory to evaluate simultaneously the electronic and optical properties of defect-free and single-vacancy blue phosphorene quantum dots. We used the generalized gradient approximation of the Perdew-Burke-Ernzerhof functional as exchange-correlation functional. We have shown that the band gaps of these quantum dots can be varies in between 2.56 eV and 2.80 eV and the band gap decreases with increasing chungculongan the system sizes. In the presence of single vacancy, the band gap significantly shrinks resulting from the shift of the conduction band towards the valence band. We also observed additional polaron states close to the Fermi level, indicating the existence of dangling bonds being established by the unbalanced charge Phosphorous atoms surrounding the defect sites. The appearance of the polaron states resulted in newly formed absorption peaks in the visible light range.
Saltwater intrusion in the Mekong Delt, an urgent problem, affected the growth of fruit trees in general and Citrus latifolia (Yu. Tanaka) Tanaka in particular. Sodium chloride in saline soils cause the water stress on plant roots leading to the leaf senescence and death of plant. văn bản luật The salinity stress promoted the ligninization in the rhizosphere parenchyma cells, reduced the root renewal and elongation. In addition, treatments for the plant recovery were also carried out by irrigating at the roots and spraying KNO3 10 g/L solution on the leaves.
Surface states spectrum of Pb2Pd is also studied, which further claims Pb2Pd to have topological non-trivial band structure. High fusion triple product has been obtained in the advanced scenarios with high normalized beta (βN) on the Experimental Advanced Superconducting Tokamak . A record value of ni0Ti0τE∼ 1.0×1019 m−3 keV s for EAST deuterium plasma has been achieved, which is due to the formation of strong and broad internal transport barriers in ne, Te and Ti profiles. Analysis shows that the strong ITB formation could be attributed to the reduction of transport from ITG modes. Based on the analysis, the physical mechanisms and methods to further improve the plasma performance are discussed.

The optimal range of LIBS spectrum for mineral pigments was determined using the similarity value between two different types of samples of the same pigment. A mineral pigment LIBS database was established by comparing the spectral similarities of tablets and simulated samples, and this database was successfully used to identify unknown pigments on tablet, simulated, and real mural debris samples. The results show that the SMA method coupled with the LIBS technique has great potential for identifying mineral pigments. We also recognize that tool kéo mem telegram is a major factor in student’s lives outside of the school environment. As such we educate and prepare students for their “digital life” by incorporating the Common Sense Media Digital Citizenship Program into our curriculum.
In fact, we show that the differential conductance of junctions containing p-wave superconductors is distinctly different from the differential conductance in junctions with s-wave superconductors, whereas the supercurrent through the junction is qualitatively similar. This is of importance for the search for Majorana fermions since it may help to design experiments to detect signatures of p-wave symmetry, which may lead to potential platforms for Majorana fermions. With the first tokamak designed for full nuclear operation now well into final assembly , and a major new research tokamak starting commissioning , nuclear fusion is becoming a mainstream potential energy source for the future. A critical part of the viability of magnetic confinement for fusion is superconductor technology.
Recent advances in pulsed field magnetization techniques now provide a fast and cost-effective method to magnetize bulk superconductors to fields of up to 5 T. The base temperature of the system is 41 K and it takes about 1 h for the system to cool down to 50 K from room temperature. A capacitor bank, combined with easily-interchangeable, solenoid- or split-type copper magnetizing coils and an insulated bipolar gate transistor acting as a high-speed từ thiện, gây quỹ switch, allows magnetic pulses to be generated with different pulse profiles. In this work, we report the results of the magnetization of a range of single-grain Y–Ba–Cu–O, Eu–Ba–Cu–O and Gd–Ba–Cu–O , bulk superconducting discs using this system. A higher trapped field was recorded using a split coil incorporating iron yokes at temperatures of 65 K and above, whereas at lower temperatures, a higher trapped field was obtained using the solenoid coil.
