The average bit error rate (BER) for binary phase-shift keying (BPSK) modulation in free-space optical (FSO) links over turbulence atmosphere modeled by the exponentiated Weibull (EW) distribution is investigated detail. effects of aperture averaging on BERs BPSK under weak-to-strong conditions are studied. EW compared with Lognormal (LN) and Gamma-Gamma (GG) distributions weak strong atmosphere, respectively. outage probability also obtained different strengths receiver sizes. analytical...
Development of a strong Lewis acid-free and phenolate-based electrolyte for rechargeable magnesium-ion batteries.
To improve the activities of non-noble metal catalysts is highly desirable and valuable to reduced use noble resources. In this work, supported nickel (Ni) nickel-platinum (NiPt) nanocatalysts were derived from a layered double hydroxide/carbon composite precursor. The characterized role Pt was analysed using X-ray diffraction (XRD), high-resolution transmission electron microscopy (HRTEM), energy dispersive spectroscopy (EDS) mapping, photoelectron (XPS) techniques. Ni2+ metallic Ni⁰ via...
Redox-active molecules, or redoxmers, in nonaqueous redox flow batteries often suffer from membrane crossover and low electrochemical stability. Transforming inorganic polyionic redoxmers established for aqueous into candidates is an attractive strategy to address these challenges. Here we demonstrate such tailoring hexacyanoferrate (HCF) by pairing the anions with tetra-n-butylammonium cation (TBA+). TBA3HCF has good solubility acetonitrile >1 V lower potential vs counterpart; thus,...
A boride-assisted method has been presented to synthesize a fused Ir nano-network supported on TiO2 as highly conductive composite catalysts (Ir NN@TiO2) for the reaction of oxygen evolution in acid. The NN@TiO2 can be utilized construct an anode catalyst layer proton exchange membrane water electrolyzer (PEMWE) with low iridium content 0.3 mgIr cm-2. low-iridium-loading PEMWE exhibits excellent performance, i.e., 2.9 cm-2@1.9 V Nafion 115 membrane, and operates stably at current density 1.0...
The effect of the addition an ionic liquid DEME·TFSI to electrolyte solution Mg(HMDS)2-MgCl2 in THF was studied electrochemically and spectroscopically. Reversible magnesium deposition/dissolution achieved with DEME·TFSI-modified electrolyte. This shows higher conductivity, a linear relationship observed between conductivity concentration Mg(HMDS)2-MgCl2. Mg-Mo6S8 coin cells have also been successfully cycled using DEME·TFSI. Raman NMR spectroscopy suggest that facilitates by improving
Redoxmers are organic molecules that serve as charge carriers in redox flow batteries. While these materials affordable and easy to source, insufficient stability of their charged states (radical ions) remains a challenge. A common reaction species is disproportionation. This reversible yields unstable multiply states, shifting the overall transfer equilibrium toward decomposition products. Here we show how kinetic controls can be engineered into redoxmer molecule suppress unwanted...
The impact of chromatic dispersion (CD) and initial chirp on the degree polarization (DOP) feedback signal in polarization-mode (PMD) compensation is analyzed. Initial affects DOP only presence CD. distortion increases not with change width due to CD chirp, but also system bit rate. It degrades PMD if same optimized threshold (less than one) chosen whenever or without presents a weak effect improvement threshold. Modifications degradation are proposed finally according simulations properties...
The impacts of polarization dependence loss (PDL) on the mode dispersion (PMD) compensation in return-to-zero (RZ) and non-return-to-zero (NRZ) modulated systems are discussed this paper. PDL affects degree (DOP) feedback PMD only presence PMD. And PDL, DOP relates not to both vectors, but also signal's states. In DOP-feedback would be more effective NRZ system than RZ system.
We present an optimal measure for the estimation of polarization light with arbitrary photon statistics. The success probability and mean fidelity are calculated, comparisons against adaptive measurement made.
Abstract China’s Sichuan Basin contains prolific gas fields and presents many drilling challenges due to the complex structural geology. Xujiahe is one of most challenging formations in basin. The interbedded hard, abrasive nature results short intervals drilled low rates penetration (ROP). Polycrystalline Diamond Compact (PDC) bits have limited efficiency this formation because impact damage wear lead very ROP. Seven-bladed PDC which replaced roller cones were once believed be...
