Stimulated Brillouin scattering (SBS) in optical fibers has long been used frequency-selective signal processing, including the realization of microwave-photonic (MWP) filters. In this work, we report a significant enhancement selectivity SBS-based MWP Filters having single passband 250 MHz–1 GHz bandwidth are demonstrated, with up to 44 dB. The filters is better than that corresponding previous arrangements by about 15 dB. shape factor filters, defined as ratio between their −20 dB and...
Direct deposition of isolated metal atoms onto substrates has been recognized as a simple route to obtain high performance supported atomically dispersed metals (SACs), however, the agglomeration driven by surface energy is difficult avoid.
Crystalline porous materials, such as metal-organic frameworks (MOFs) and covalent organic (COFs), have been demonstrated to be versatile material platforms for the development of solid proton conductors. However, most crystalline conductors suffer from decreasing conductivity with increasing temperature due releasing water molecules, this disadvantage severely restricts their practical application in electrochemical devices. In work, first time, hydrophilic carbon dots (CDs) were utilized...
Cortisol, an essential stress hormone, plays a crucial role in health monitoring, with wearable sensors providing efficient non-invasive means for continuous tracking. However, tackling the dual challenges of maintaining...
Abstract Based on density functional theory calculations under the framework of first‐principles, electronic and optical characteristics C 2 N/ZnTe van der Waals (vdW) heterostructure are investigated in detail. An inherent type‐II band alignment arises heterostructure, which possesses a 1.94 eV direct gap. With light irradiation, photogenerated electron‐hole pairs separated different monolayers. This helps to extending lifetime carriers. Additionally, lower effective carrier mass is owned...
The effects of selenium (Se)-biofortified corn on the total Se contents, antioxidant enzyme levels, and amino acids composition in Chinese mitten crab (Eriocheir sinensis) during stage fifth shelling to maturity were investigated present study. culture density crabs was 600 per 667 m², they continuously fed 120.4 mg from Se-biofortified m² every two days for 90 days. results showed that muscle levels significantly increased (p < 0.05). Activities hemolymph supernatant enzymes including...
The transmittance spectrum of a plasmonic filter has been numerically simulated by the two-dimension (2D) finite-difference time-domain method. is composed two Metal-Insulator-Metal waveguides and resonator with different rings. results show that rising edge asymmetric steeper than symmetric one at each pass band. By embedding liquid crystal in resonator, can act as an electro-optical switch. These potential applications on nano-optical devices.
Abstract Poly[2,2′‐( p ‐oxydiphenylene)‐5,5′‐bibenzimidazole] (OPBI) was polymerized in poly(phosphoric acid) (PPA) with the presence of pristine nanodiamonds (NDs) (0.2–5 wt %) to fabricate NDs‐ g ‐OPBI/OPBI nanocomposites via Friedel–Crafts (F‐C) reaction. The OPBI chains were successfully attached NDs through F‐C reaction between carboxylic acid from and NDs, which proved by nuclear magnetic resonance, X‐ray photoelectron, diffraction. show more homogeneous dispersion than physical...
A novel optical fiber amplifier based on interacting between semiconductor quantum dots luminescence and evanescent wave was proposed in this paper. This amplifier, named here as amplified (SQDAF), fabricated by depositing PbS a fused tapered coupler. The simple reverse micelle method applied to synthesize the dots. By optimizing synthesis procedure, size of particles controlled their solution exhibited obvious photoluminescence blue shift effect which observed fluorescent spectrometer. gain...
In order to improve the therapeutic effect, prolong action time and reduce side effects of first generation thrombolytic drug urokinase (UK), a novel UK/multi-walled carbon nanotubes (MWCNTs)-chitosan (CS)-arginine-glycine-aspartic acid (Arg-Gly-Asp) (RGD) delivery system was synthesized by chemical bonding/non covalent bond modification/ultrasonic dispersion. The results showed that diameter UK/MWCNTs-CS-RGD about 30-40 nm, there layer UK attached surface tube wall, distribution relatively...
In this paper we discuss the magnetoelectric (ME) effect in bilayers of Nickle Zinc ferrite (NZFO) and lead zirocnate titanate (PZT). The powder NZFO was prepared by sol-gel technique, then hot-pressed at 900℃, sintered high temperatures. these measured strong interaction observed that transverse ME higher than longitudinal one order magnitude, tended to be stronger as sintering temperature increased. When increased from 950℃ 1380℃, maximum voltage coefficient could change range 25.6 mV...
A method for tunable microwave-photonic and optical filtering of broadband waveforms is proposed demonstrated.
