Importance Tongxinluo, a traditional Chinese medicine compound, has shown promise in vitro, animal, and small human studies for myocardial infarction, but not been rigorously evaluated large randomized clinical trials. Objective To investigate whether Tongxinluo could improve outcomes patients with ST-segment elevation infarction (STEMI). Design, Setting, Participants Randomized, double-blind, placebo-controlled trial was conducted among STEMI within 24 hours of symptom onset from 124...
The progressive damage behavior and failure mechanism of molded carbon fiber reinforced composite laminates under tensile three-point bending loads were studied. mechanical properties studied by theoretical analysis, numerical simulation experimental characterization. results show that the mode presents phenomenon resin matrix cross-section fracture, fracture pull-out. Under load, main modes are crack, interlayer separation fracture. Based on energy dissipation theory incremental method,...
In order to enhance the quality and mechanical properties of 3D printing carbon fiber reinforced composite (CFRP) workpiece, this paper prepares CFRP laminates by proposing a layered coherent scanning path, carries out orthogonal tests single factor disclose effects different process parameters (i.e., layer thickness, first nozzle temperature speed) on performance workpieces. Moreover, The grey relation analysis method is used analyze multi-objective results are optimized based results....
Carbon fiber reinforced aluminum laminates (CARALL) are often subjected to bending loads in actual working conditions, resulting some imperceptible intra-layer or inter-layer damages, such as matrix cracking, fracture and delamination, which degrade the mechanical properties of structure. In this paper, performance damage mechanism CARALL tested simulated by finite element simulation. Firstly, analyzed three-point test, morphology specimen after failure is photographed scanning electron...
Photoluminescence (PL) spectra of single-crystal ZnO bulk under hydrostatic pressure are studied using the diamond-anvil-cell technique at room temperature. The PL spectrum single crystal taken atmospheric was dominated by a strong near-band-edge exciton emission. emission line found to shift towards higher energy with increasing applied pressure. By examining pressure-dependent spectral features, coefficient direct Γ band gap wurtzite determined. deformation potential has also been deduced...
ZnO hexagonal prisms have been grown from poly (vinylpyrrolidone)-assisted electrochemical assembly onto p-type Si (111) substrate. These arrays are highly (0002) orientated. The (0001) end facets and {1010} side of the well defined. photoluminescence (PL) spectrum these shows an intense ultraviolet near band-gap emission with a full width at half maximum 86 meV room temperature. low-temperature PL is split into well-resolved free bound exciton lines. temperature dependence intensities...
Carbon Fiber Reinforced Polymer (CFRP) laminates habitually experience either tensile or compressive prestressing loads and are simultaneously susceptible to external low-velocity impacts in genuine operating scenarios. The current study establishes a meticulous model elucidate the low-speed impact behavior of prestressed CFRP laminates, substantiated by finite element simulations. Initial validation is accomplished comparing simulated scenarios without prestress against experimental data....
Due to their excellent mechanical properties, Carbon fiber reinforced aluminum laminates (CARALL) are widely used in aerospace, transportation, military and navigation fields. In this study, a method of preparing CARALL by molding process was introduced. We obtain two kinds CARALL, Al-CFRP-Al laminated plate CFRP-Al-CFRP plate. Then we tested tensile properties. The experimental results indicated that the properties were 865.1 MPa, while 718.2 MPa. comparison pure alloy, strength both had...
Considering the anisotropic characteristics of carbon fiber reinforced composites, couple stress theory was modified, and loading model microscale Mindlin laminates in a hygrothermal environment established. The material scale parameters affected by were introduced, governing equations boundary conditions solved using principle virtual work. Taking four-sided simply supported square laminate orthogonal layer as an example, displacement function Navier solution method set to calculate...
