In this paper, we demonstrate the generation of high-performance entangled photon-pairs in different degrees freedom from a single piece fiber pigtailed periodically poled LiNbO$_3$ (PPLN) waveguide. We utilize cascaded second-order nonlinear optical processes, i.e. second-harmonic (SHG) and spontaneous parametric down conversion (SPDC), to generate photon-pairs. Previously, performance photon pairs is contaminated by Raman noise photons pigtails. Here integrating PPLN waveguide with...
Quantum teleportation can transfer an unknown quantum state between distant nodes, which holds great promise in enabling large-scale networks. To advance the full potential of teleportation, states must be faithfully transferred at a high rate over long distance. Despite recent impressive advances, high-rate system across metropolitan fiber networks is extremely desired. Here, we demonstrate transfers carried by independent photons 7.1 ± 0.4 Hz 64-km-long channel. An average single-photon...
The water content of proton exchange membrane fuel cells (PEMFCs) affects the transport reactants and conductivity membrane. Effective management measures can improve performance extend lifespan cell. state stack is influenced by various external operating conditions, optimizing combination these conditions within stack. Considering that stack's internal resistance reflect its state, this study first establishes an resistance-operating condition model considers coupling effect temperature...
Abstract Standalone multi‐energy hub is the next frontier of electric grid modernization. It vital to optimize standalone capacity configuration enhance reliability, economic efficiency, and sustainability. Therefore, this paper proposes a novel multi‐objective model for considering electricity, heat hydrogen energy uncertainty. First, with heat, established. takes into account photovoltaic generators, wind generation, combined power units, gas, gas boiler storage tank meet electrical,...
A solid-state polymer electrolyte membrane is formed by blending poly(vinylidene fluoride-co-hexafluoropropylene) with the synthesized copolymer of poly(methyl methacrylate-co-1-vinyl-3-butyl-imidazolium bis(trifluoromethanesulfonyl)imide, in which lithium bis(trifluoromethane)sulfonimide molecules are applied as source ions. The accordingly that contains 14 wt.% P(MMA-co-VBIm-TFSI), 56 PVDF-HFP, and 30 LiTFSI manifests best electrochemical properties, achieving an ionic conductivity 1.11 ×...
The effects of dispersion method for ink preparation and types catalyst on the layer’s structure characteristics were investigated. Catalyst layers prepared by two methods, i.e., sonication ball-milling, catalyst: Pt-HSC (High Surface Area) Pt-Vulcan XC-72, fabricated. Viscosity, particle size distribution inks, surface properties, cell performance measured. Experimental results with at ionomer/carbon weight ratio 0.8 show that dispersity strongly depends mixing large agglomerates form in...
A multisource energy storage system (MESS) among electricity, hydrogen and heat networks from the operator's prospect is proposed in this article. First, framework device model of MESS established. On basis, a multiobjective optimal dispatch strategy proposed. Considering influence time-of-use price, our can achieve unified effect economy, efficiency, stationarity. Ultimately, applied to study characteristic economic benefits, loss, power fluctuation, etc. The results show that be profitable...
Heralded single photon source (HSPS) is an important way in generating genuine photon, having advantages of experimental simplicity and versatility. However, HSPS intrinsically suffers from the trade-off between heralded rate purity. To overcome this, one can apply multiplexing technology different degrees freedom to enhance performance HSPS. Here, by employing spectral active feed-forward manipulating, we demonstrate a at 1.5 {\mu}m telecom-band. Our results show that effectively erases...
Palladium is an active catalyst for the electro-oxidation of formic acid, making it attractive as anode direct acid fuel cells. However, exhibits significant decay under constant current operation, unsuitable use in any cell application unless can be regenerated. The buildup poisons, including a means regenerating catalyst, investigated using chronopotentiometry and reported here. After poisoning has occurred, operation at voltage vs dynamic hydrogen electrode recovers performance equivalent...
