Abstract :

The plasmonic photocatalyst of Ag-Bi2WO6 was employed to investigate the effect of surface plasmon resonance (SPR) on the visible-light photocatalytic activity. Generally, it is accepted that metal nanoparticles as electron traps on the surface of semiconductor photocatalyst can effectively inhibit the recombination of photo-generated electron-hole pairs, provide more active sites and thereby enhance the photocatalytic activity. Nevertheless, SPR effect confirmed in Ag-Bi2WO6 plays an important role in the photoreaction enhancement in the meantime. In this case, a facile and more efficient method was introduced to synthesize Ag-Bi2WO6 hetero-architecture on basis of an ascorbic-acid-assisted route. The results and analysis show that a optimize photocatalytic efficiency can be achieved by elaborately manipulating SPR effect. For instance, the highest photocatalytic efficiency of 96.46% after 150 min visible-light irradiation was obtained as the molar ratio of Bi2WO6:Ag is 10:2, which suggest that it would be a promising candidate for photo-catalysis application. Eventually, a possible mechanism for the formation of Ag-Bi2WO6 hetero-architecture and its enhanced photocatalytic activity was proposed and discussed. © 2018 Elsevier GmbH

Abstract :

Energy storage materials have received increasing attention for sustainable energy production and use. Despite the excellent properties of ferroelectric/antiferroelectric ceramics, PVDF-based co/terpolymer films, and related composites, few materials meet the high-performance energy storage requirements. Here, we design antiferroelectric composites by combining anti-ferroelectric fillers with a high dielectric permittivity and ferroelectric copolymers with high breakdown fields. As a result, a high discharge energy density of 2.9 J/cm3 under much lower fields, i.e., 175 MV/m is realized. Such high-performance antiferroelectric composites could aid in the further development of promising new energy storage materials. © 2018 Elsevier Ltd and Techna Group S.r.l.

Abstract :

In2O3/ITO thin film thermocouples (TFTCs) with alumina protecting layer were fabricated on alumina substrates. The effects of protecting layer on their performance at higher temperature and long term service were investigated accordingly. In2O3 and ITO thin films were prepared by radio frequency magnetron sputtering methods, while the alumina protecting layer was prepared by traditional spin-coating methods. Microstructural and thermoelectric properties of the In2O3/ITO TFTCs with and without alumina (Al2O3) protecting layer were investigated as a function of sintering time from 2 to 10 h at 1250 °C. The results show that, the existence of alumina protecting layer can effectively increase the performance capabilities of thermocouples at high temperatures by inhibiting the volatilization of the thin film. In2O3/ITO TFTCs with protecting layer can work normally over 10 h at 1250 °C while Seebeck coefficient is 131.7 µV/°C. The drift rate can reach 3.05 °C/h, which is much better than those without protecting layer. © 2018, Springer Science+Business Media, LLC, part of Springer Nature.

Abstract :

Oxygen evolution reaction (OER) is an important kinetic process in many important renewable energy applications, while high-efficiency electrocatalysts, especially efficient non-precious metal catalysts, are very essential to overcome substantial overpotential and sluggish kinetics of OER. Here, three-dimensional (3D) Ti3C2 based conductive network structure was firstly constructed by an absorption of 2D few-layer Ti3C2 flakes (MXene) onto 3D nickel foam (NF) network, and then ultra-small sulfur-incorporated nickel ferrite nanosheets (S-NiFe2O4) were grown on the 3D Ti3C2 based conductive network structure (abbreviated as S-NiFe2O4@Ti3C2@NF) by combining a facile thiourea-assisted electrodeposition process with a low-temperature calcination process. Results indicate that the as-fabricated S-NiFe2O4@Ti3C2@NF hybrid electrode exhibits a superior OER activity, which includes only 1.50 V vs. RHE to afford a current density of 20 mA cm−2, a Tafel slope of 46.8 mV dec−1 and excellent catalytic stability in 1 M KOH. Excellent OER performances are attributed to the favorable 3D hierarchical network structure and relatively fast electron transport provided by the few-layer Ti3C2 flakes matrix, good catalytic activity and abundant catalytic active sites from the ultra-small S-NiFe2O4 nanosheets, synergistically. This work could open a feasible way for achieving a new type of 3D MXenes based hierarchical network structure for renewable energy applications. © 2018 Elsevier Ltd

Abstract :

This paper proposed a cross-polarization converter, which can fully control the transmission phase and then manipulate the direction of refracted wave. A multi layered unit cell was designed and the transmission phase is continuously controlled by a single geometric parameter, which brings great convenient for simultaneously manipulating the polarization and propagation direction of the transmitted wave. The cross-polarized transmittance of the proposed polarization converter is higher than 0.9. In addition, the transmitted wave has an extremely low co-polarized component. Thus, the polarization conversion ratio is nearly 100%. Anomalous refraction was also realized by configuring a designed transmission phase distribution on the aperture of the cross-polarization converter. The proposed device was demonstrated by both simulation and measurement. © 2018 Elsevier GmbH

Abstract :

Ferroelectrics with high electrostrictive properties are of great interest in fundamental researches and industrial applications. In this work, the phase structural evolution, dielectric properties as well as electrostrictive properties in barium strontium titanate [(Ba1-xSrx)TiO3, BST] lead-free ferroelectrics with x from 0.05 to 0.4 were investigated in details. High electric field-induced strain (∼0.2%) at 60 kV/cm are obtained in x = 0.05 and 0.1 compositions. More importantly, almost purely positive strains with ultra-low hysteresis (<8%) determined from bipolar strain-electric field curves are observed in compositions with x from 0.05 to 0.3, suggesting the dominating role of electrostrictive effect. Temperature-insensitive and composition-insensitive longitudinal electrostrictive coefficient Q33 for BST ceramics with giant values from 0.0409 m4/C2 to 0.0479 m4/C2 is identified. These features suggest that BST ceramics not only possess high electric field-induced strain with ultra-low hysteresis and giant Q33, but also are good candidates for potential application in high-precision actuator devices. © 2018 Elsevier Ltd

Electric Field Tuning of Anisotropic Magnetoresistance in Ni-Co/PMN-PT Multiferroic Heterostructure EI Scopus SCIE
期刊论文 | 2019 , 55 (2) | IEEE Transactions on Magnetics
Abstract&Keyword Cite

Abstract :

Electric field tuning of anisotropic magnetoresistance (AMR) effect is investigated in Ni-Co/PMN-PT multiferroic heterostructure. The AMR ratio increases with the electric field when an external magnetic field is perpendicular to the applied current and decreases when the magnetic field is parallel to the current, showing anisotropic tunability of AMR due to the change of magnetization orientation induced by strain-mediated magnetoelectric coupling. A magnetic sensor with hall bar geometry is developed based on AMR effect in Ni-Co/PMN-PT heterostructure. The linear output range of the AMR sensor is enhanced by 250&#x0025; with the applied electric field, and stable electrical response to the external magnetic field is demonstrated. The electrically tunable AMR effect has great potential for applications in magnetic field sensors with enhanced measurement range and sensitivity. IEEE

A comparative study of planar and mesoporous perovskite solar cells with printable carbon electrodes EI SCIE

Abstract&Keyword Cite

Abstract :

Devices with printable carbon electrodes are promising directions for the commercialization of perovskite solar cells. Most of perovskite solar cells employ mesoporous device structures when using printable carbon as the counter electrodes. Here, we carry a comparative study of planar and mesoporous perovskite solar cells with carbon electrodes. The device efficiency is significantly reduced from 11.37% to 5.27% when the mesoporous TiO2 film is removed from the device structure. Compared with the planar device, smaller carrier transport resistance and bigger carrier recombination resistance are demonstrated for the mesoporous device. Results suggest that the presence of mesoporous TiO2 enables an efficient electron extraction from the perovskite absorber, which remits the serious carrier recombination in the hole transport layer free device due to the hole accumulation. Therefore, the electron extraction efficiency is crucial in these hole transport layer free devices with carbon electrodes. This study helps to develop further optimization of low temperature carbon-based perovskite solar cells for higher reproducibility and higher device performance. © 2018 Elsevier B.V.

Abstract :

A simple, rapid response time and ultrahigh sensitive chemiluminescence (CL) DNA assay based on Fe3O4@SiO2@Au-functionalized magnetic nanoparticles (Au-MNPs) was developed for detection of p53 tumor suppressor gene. In this study, 2',6'-dimethylcarbonylphenyl-10-sulfopropyl acridinium-9-carboxylate 4'-NHS ester (NSP-DMAE-NHS), as a new kind of highly efficient luminescence reagent, was immobilized on the complementary sequence of the wild-type p53 (ssDNA) to improve the detection sensitivity. The optimal concentration of ssDNA-(NSP-DMAE-NHS) conjugates mixed with the wild-type p53 (wtp53) samples respectively. Then, the wtp53-Au-MNPs conjugates were added to continue the competitive reaction in the above solution. Subsequently, the Au-MNPs separated under magnetic field, measured by a homemade luminescent measurement system. Under optimal conditions, the method exhibited ultrasensitive sensitivity with a detection limit of 0.001 ng mL<sup>-1</sup> (0.16 pM), a wide range of liner response from 0.001 ng mL<sup>-1</sup>~6.6 μg mL<sup>-1</sup>. Therefore, the immunomagnetic nanocomposites-based detection strategy was rapid, low-cost, and highly sensitive that can be easily extended to the early diagnosis of cancer development and monitoring of patient therapy.
