In this paper, we theoretically investigated external electric field-dependent photoinduced charge transfer (CT) in a donor–acceptor (D-A) system two-photon absorption (TPA) where PCDTBT and PC70BM were selected as the D A, respectively. Using our developed visualization methods, can directly observe dynamic processes of CT each step different transition channels TPA with two-dimensional density matrix three-dimensional difference density. Our results revealed that strong peaks be resulted...
This study systematically investigated the microstructural evolution and mechanical properties of GH4780 superalloy under various solution treatment conditions. Experimental results reveal a strong temperature dependence grain growth kinetics, with average diameter increasing from approximately 20 μm to 194 as rises 1020 °C 1110 °C. Mechanical testing demonstrates that coarsening reduces yield strength by 19% at room (from 920 MPa 743 MPa) 9.5% 760 707 640 MPa), primarily due decreased...
Oxidative injury is involved in many diseases, including ischemic and neurodegenerative diseases. Antioxidant drugs can be used to relieve the oxidative caused by these diseases; however, there are very few antioxidant available for clinical use. In this study, we found that 5-(hydroxymethyl)-2-furfural (5-HMF) protects against damage induced cerebral ischemia rats or hydrogen peroxide (H2O2) PC12 cells. We demonstrated 5-HMF performs function via apurinic/apyrimidinic endonuclease/redox...
Phase diagrams of quasicrystal-forming alloy systems, such as Al-Cu-Fe, are essential to the continued development and fundamental understanding quasicrystalline alloys, especially for synthesis single quasicrystals. Isothermal sections Al-Cu-Fe system at 700, 800, 1000 °C were constructed over whole composition range by investigations three Cu/Fe/Al5Fe2 diffusion triples forty-seven equilibrated alloys using scanning electron microscopy (SEM), probe microanalysis (EPMA), X-ray diffraction...
The stamping formability of Mg–3Al–1Zn (AZ31) alloy was greatly enhanced through weakening (0001) basal texture by repeated unidirectional bending (RUB). After RUB and subsequent annealing, the max intensity AZ31 Mg weakened from 10.7 to 6.3 thus Schmid factor for <a> slip system increased 0.25 0.29. prepared in annealed condition possessed better than original sheet at 373 K, e.g., larger Erichsen value (7.5 mm vs. 5.5 mm), higher wider forming limit diagram (FLD), limiting drawing ratio...
AZ31 magnesium alloy sheets were prepared by low-speed extrusion at different temperatures, i.e., 350 °C, 400 and 450 °C. The microstructure evolution mechanical properties of extruded studied. Results indicate that the obviously improved alloys. As temperature decreased, grain size for produced (0001) basal texture intensity increased. yield strength tensile greatly increased as decreased. sheet °C exhibited finest best properties. average size, strength, elongation ~2.7 μm, ~226 MPa, ~353...
Phase diagram and diffusion coefficients of the Fe-Zn binary system are required to predict control microstructure galvanized zinc coatings thus were systematically investigated in temperature range from 700 1100 °C using nine novel Fe/Zn liquid-solid couples (LSDCs). The equilibrium compositions α Γ phases determined agree well with recently established phase diagram. extracted interdiffusion α-Fe at temperatures between 750 forward-simulation analysis (FSA) extend experimental...
Knowledge of the phase stability in Al–Co–Fe ternary system is critical for developing Al–Fe–Si-based low-cost lightweight high-temperature materials and thus experimentally investigated over whole composition range. Three complete isothermal sections at 1000, 900, 800 °C were constructed based on results measured from three identical Co/Fe/Al5Fe2 diffusion triples forty-three equilibrated alloys using scanning electron microscopy (SEM), probe microanalysis (EPMA), X-ray diffraction (XRD)....
