The dosage tablet was controlled by number layers. content, dose...
Epitaxial BaTiO3 (BTO) films have been grown on Nb-doped SrTiO3 (NSTO) (0 0 1) substrate. The ferroelectric resistive switching effect and memristive behaviours observed in Pt/BTO/NSTO heterostructures. It exhibits two resistance states under different polarization, both current–voltage curves are nonlinear, slightly asymmetric free of discontinuities, contrast with what often occurs other devices. In addition, the can be continuously tuned up to 1.3 × 105% by varying pulse voltage...
The aim of this study was to determine the effect varying excipient content on formation and physical properties 3 D printed tablets. Fifteen different preparations were formed into tablets with radii 5 mm thickness 2 mm, using binder jetting (BJ). analyzed by assessing visual microstructural appearance, friability, hardness, disintegration time. We found that filling agents high water solubility (e.g. D-sucrose), binding a viscosity in solution polyethylene glycol 4000) moistening agent...
A method is proposed to modulate phase using variant square holes in a metallic film based on fundamental mode approximation model. Phase retardation through subwavelength scale thin metal has been analyzed and calculated. Based the model, structured lens with numerical aperture of 0.583 focal length 240 microm formed by 2D hole array designed. Numerical simulation finite-difference time-domain carried out, results agree theoretical analysis. spot close diffraction limit can be obtained.
We present a compact high-efficiency and high-average-power diode-side-pumped Nd:YAG rod laser oscillator operated with linearly polarized fundamental mode.
