In this paper, we demonstrate high-density nanolithography by utilizing surface plasmons (SPs). SPs are excited on an aluminum substrate perforated with 2-D hole arrays using a near UV light source in order to resolve sub-wavelength features high transmission. Our lithography experiments 365 nm wavelength 90 dot array patterns 170 period, well beyond the diffraction limit of far-field optical lithography. transmission measurements, strong and wavelength-dependent observed, which confirms...
We report systematic design and formation of plasmonic perovskite solar cells (PSCs) by integrating Au@TiO2 core-shell nanoparticles (NPs) into porous TiO2 and/or semiconductor capping layers. The effects in the formed PSCs are examined. most efficient configuration is obtained incorporating NPs both layers, which increases power conversion efficiency (PCE) from 12.59% to 18.24%, demonstrating over 44% enhancement, compared with reference device without metal NPs. PCE enhancement mainly...
We observed a universal phenomenon of the competition among multiple filaments generated during propagation intense femtosecond laser pulses in air. show that fluorescence signal from excitation nitrogen molecules inside plasma channel contains important information pertaining to formation and interaction filaments. The detected backscattered yielded irregular changes shot which cannot be explained by fluctuation arising initial pulse itself. Numerical simulations reveal complex dynamics...
Achieving high open-circuit voltage and short-circuit current density simultaneously is a big challenge in the development of highly efficient perovskite solar cells, due to complex excitonic nature hybrid organic-inorganic semiconductors. Herein, we developed facile effective method fabricate plasmonic PSC devices. The cells were prepared by incorporating Au nanoparticles (NPs) into mesoporous TiO2 films depositing MgO passivation film on NP-modified titania via wet spinning pyrolysis...
Serum exosomal microRNAs (miRNAs) have been suggested as novel biomarkers for various diseases, especially gastric cancer (GC). But circulating Chronic atrophic gastritis (CAG) which is defined precancrerous lesions of GC remain largely elusive. To investigate serum miRNAs that are differently expressed in CAG patients and nonatrophic (CNAG) may be helpful its diagnosis therapy.Patients were recruited according to the exclusioncriteria. RNA was extracted from exosomes 30 CNAG patients. The...
A new type of molecular fragmentation induced by femtosecond intense laser at the intensity 2 x 10(14) W/cm2 is reported. For parent molecule methane, ethylene, n-butane, and 1-butene, fluorescence from H (n = 3-->2), CH (A 2Delta, B 2Sigma-, C 2Sigma+-->X 2Pi), or C2 (d 3Pi g-->a u) observed in spectrum. It shows that a universal property neutral field. Unlike breaking only one two chemical bonds conventional UV photodissociation, caused undergoes vigorous changes, most molecule, like an...
Four-layered plasmonic structures of glass/Au/TiO2/NaYF4:Yb, Er, Gd nanorods were fabricated and tremendous improvement in upconversion luminescence (UCL) was observed under infrared 980 nm excitation. The TiO2 film used as an oxide spacer. emission intensity the (UC) strongly modulated by thickness layer. extent modulation depended on separation distance between Au layer UC nanorods. A maximum UCL enhancement 192-fold for one green (540 nm) when a 10 nm-thick used; 150-fold other (521 at...
We present for the first time synthesis of Eu3+-doped β-phase sodium gadolinium fluoride (NaGdF4:Eu) nanocrystals (NCs) using a hydrothermal method and application down conversion (DC) NaGdF4:Eu NCs to efficient dye-sensitized solar cells (DSSCs). The as-prepared NaGdF4:Eu3+ were characterized by X-ray diffraction, photoluminescence spectrometry, scanning transmission electron microscopy. DC layers consisting poly(methyl methacrylate) (PMMA) doped with luminescent prepared attached onto back...
A new family of platinum acetylide derivatives containing iptycene building blocks end-capped with 3,4,5-tris(alkoxy)phenyl substituents has been successfully synthesized. The structure the newly designed complexes was characterized by multinuclear NMR (1H, 31P, and 13C) mass spectroscopy elemental analysis. Unexpectedly, all compounds presented good gel formation properties in some common organic solvents. morphology xerogels investigated scanning electron microscopy (SEM). An investigation...
Li-rich transition metal oxides (Li1+XM1–XO2) are known as the next generation of cathode materials for lithium-ion batteries by reason their high specific capacity. However, oxygen release and structural conversion in layered during initial charge result low Coulomb efficiency (ICE) uninterrupted capacity attenuation. In this paper, we show a molten vanadate-assisted strategy at temperature combined with washing treatment to regulate amount labile removed from surface oxide...
Constrained Variational Inequality (CVI) is a general optimization framework used to model and solve complementarity equilibrium problems. In this paper, we first present novel Accelerated Operator Extrapolation (ACOE) method for solving single-constrained monotone variational inequality (sCMVI) We demonstrate that ACOE significantly improving the convergence rate sCMVI problems O (1/k) in terms of both operator constraint's first-order evaluations, matching optimal performance unconstrained...
