    Details
    In: Solar RRL, Wiley
    Abstract: Inorganic perovskite solar cells have attracted considerable interest for their thermal stability. This study explores turmeric and carotene natural dyes as additives for refining CsPbBr 3 film crystal structure. These dyes enhance light absorption and carrier transport by increasing CsPbBr 3 crystal size and reducing defects. Capitalizing on the dyes’ light‐absorbing nature and their impact on device energy levels, turmeric and carotene additives elevate efficiency from 5.35% to 9.78% and 7.81%, respectively. Remarkably, device stability extends 90 days without encapsulation. This work introduces an eco‐friendly, economical method to optimize perovskite crystallization and enhance optoelectronic properties in inorganic perovskite solar cells.

    Abstract: Nitrogen‐doped graphene (NG) with wrinkled and bubble‐like texture is fabricated by a thermal treatment. Especially, a novel sonication‐assisted pretreatment with nitric acid is used to further oxidize graphene oxide and its binding with melamine molecules. There are many bubble‐like nanoflakes with a dimension of about 10 nm appeared on the undulated graphene nanosheets. The bubble‐like texture provides more active sites for effective ion transport and reversible capacitive behavior. The specific surface area of NG (5.03 at% N) can reach up to 438.7 m 2 g −1 , and the NG electrode demonstrates high specific capacitance (481 F g −1 at 1 A g −1 , four times higher than reduced graphene oxide electrode (127.5 F g −1 )), superior cycle stability (the capacitance retention of 98.9% in 2 m KOH and 99.2% in 1 m H 2 SO 4 after 8000 cycles), and excellent energy density (42.8 Wh kg −1 at power density of 500 W kg −1 in 2 m KOH aqueous electrolyte). The results indicate the potential use of NG as graphene‐based electrode material for energy storage devices.

    Abstract: Silver nanowires and graphene were used to form networks within acrylic resin to improve its toughness and conductivity through silane coupling agent. Meanwhile, acrylic resin was favorable to the adhesion of graphene to glass substrates and the connection among graphene sheets to form films. Experimental results indicate that after annealing at 400°C, sheet resistances of graphene‐silver nanowire films were lower than those graphene films without silver nanowires. The findings in this study provide helpful information on the fabrication of graphene‐based electronic devices. © 2015 Wiley Periodicals, Inc. J. Appl. Polym. Sci. 2015 , 132 , 42387.

    Abstract: Recently, binary transition metal oxides, phosphates, and sulfides have attracted wide attention due to their potential applications in supercapacitors. The emergence of metal‐organic frameworks (MOFs) provides new opportunities for the synthesis and investigation of porous binary metal compounds with similar microstructures. Herein, binary metal oxide (NiCo‐O) tubular structures are derived from NiCo‐MOF‐74 via a facile annealing process, and then phosphate (NiCo‐P) and sulfide (NiCo‐S) structures are obtained from NiCo‐O by heat treatment and solvothermal process, respectively. Among the three derivatives, NiCo‐S with nanosheet structures has the highest specific capacitance of 930.4 F g −1 at a current density of 1 A g −1 and an excellent rate capability with a retention of ≈80% at 10 A g −1 . The long‐term cycling performance of NiCo‐S is superior with 70.5% retention after 10 000 cycles. The hybrid supercapacitor device with NiCo‐S and activated carbon as positive and negative electrodes delivers a high energy density of 22.6 W h kg −1 at a power density of 800 W kg −1 . The excellent performance of NiCo‐S can be attributed to its nanosheet structure, which increases the specific surface area and electroactive sites.

    In: Solar RRL, Wiley, Vol. 4, No. 9 ( 2020-09)
    Abstract: A desirable counter electrode material for dye‐sensitized solar cells (DSSCs) needs to have superior electrocatalytic activity, low charge‐transfer resistance, and long‐term stability. Herein, the development of a composite of nitrogen‐doped carbon nano‐onions with modified reduced graphene (N‐CNOs/mGr) to achieve these merits is reported. The mGr network has high electrical conductivity to improve charge transfer; the N‐CNOs with pyridinic and graphitic N provide more electrocatalytic active sites for the reduction of I 3 − to I − , and the carbon composite demonstrates excellent electrochemical stability. The constructed DSSC with the N‐CNOs/mGr electrode presents better long‐term stability and a higher power conversion efficiency of 10.28% than those devices with conventional Pt (6.54%) and mGr (5.11%) electrodes. Therefore, the all carbon‐based composite will open up new opportunities for a variety of electrochemical device applications.

    Influence of bovine serum albumin on biodegradation behavior of pure Zn
    Wiley ; 2022

    Abstract: Zinc is emerging as a promising biodegradable metal for temporary implant applications. In this work, we investigate the influence of bovine serum albumin (BSA)—the most abundant blood protein in simulated body fluid (SBF) on degradation of pure Zn via electrochemical measurements and long‐term immersion. Electrochemical experiments indicate a decrease of the corrosion rate of bare Zn with increasing BSA concentration in solution for short‐term exposures. Samples were characterized with scanning electron microscope (SEM) (including energy dispersive spectroscopy [EDS], X‐ray photoelectron spectroscopy [XPS] , Fourier transform infrared spectroscopy [FTIR], and time‐of‐flight secondary ion mass spectrometry [TOF‐SIMS] ) after immersion up to 21 days. Presence of BSA in the electrolyte, decrease the amount of Ca‐phosphate precipitation on Zn surface. However, a more compact surface layer formed in the presence of BSA in solution. Most noteworthy, in long‐term exposures, BSA enhances localized corrosion of Zn—such detrimental localized attack was not observed in BSA‐free solution. We suggest that a sealed space forming between the Zn substrate and a protein adsorption layer restricts mass transport, thus triggering localized corrosion of Zn.

    Signal recovery and noise suppression of the Ocean‐Bottom Cable P ‐component data based on improved dense convolutional network
    Wiley ; 2023
    In:  Geophysical Prospecting
    Details
    In: Geophysical Prospecting, Wiley
    Abstract: Effective attenuation of noise in seismic data is important for high‐quality seismic imaging. Noise suppression in Ocean‐Bottom Cable data is particularly challenging. The challenge for the geophysicist is to process the individual hydrophone and vertical geophone data up to a level where they can conveniently be combined for effective multiple suppressions. In this study, we propose a deep learning‐based solution for noise attenuation and signal recovery of the P ‐component of Ocean‐Bottom Cable data. To effectively attenuate complex noise, a denoising model based on dense convolutional network is proposed for Ocean‐Bottom Cable data processing. The backbone of the denoising network uses dense blocks to extract the potential features. Dense connections are applied to fuse the features at each stage to further enhance the effective information and thus improve the reconstruction of the signal. A high‐quality training set was built for the training network to ensure that the trained model was suitable for noise suppression. Synthesis and field experiments show that the proposed method can completely eliminate complex noise and recover weak signals from the P ‐component data of the Ocean‐Bottom Cable data.

    Titania‐Supported Cu‐Single‐Atom Catalyst for Electrochemical Reduction of Acetylene to Ethylene at Low‐Concentrations with Suppressed Hydrogen Evolution
    Wiley ; 2023
    In:  Advanced Materials
    Details
    In: Advanced Materials, Wiley
    Abstract: Electrochemical acetylene reduction (EAR) is a promising strategy for removing acetylene from ethylene‐rich gas streams. However, suppressing the undesirable hydrogen evolution is vital for practical applications in acetylene‐insufficient conditions. Herein, Cu single atoms are immobilized on anatase TiO 2 nanoplates (Cu‐SA/TiO 2 ) for electrochemical acetylene reduction, achieving an ethylene selectivity of ≈97% with a 5 vol% acetylene gas feed (Ar balance). At the optimal Cu‐single‐atom loading, Cu‐SA/TiO 2 is able to effectively suppress HER and ethylene over‐hydrogenation even when using dilute acetylene (0.5 vol%) or ethylene‐rich gas feeds, delivering a 99.8% acetylene conversion, providing a turnover frequency of 8.9 × 10 −2  s −1 , which is superior to other EAR catalysts reported to date. Theoretical calculations show that the Cu single atoms and the TiO 2 support acted cooperatively to promote charge transfer to adsorbed acetylene molecules, whilst also inhibiting hydrogen generation in alkali environments, thus allowing selective ethylene production with negligible hydrogen evolution at low acetylene concentrations.

    Abstract: Distributed acoustic sensing technology is a new type of signal acquisition technology, and this technology has been widely used in obtaining vertical seismic profile data in recent years. Distributed acoustic sensing technology has the advantages of high sampling density and strong tolerance to a harsh environment. However, in the real distributed acoustic sensing–vertical seismic profile data, the effective signal will be annihilated by various noises, which significantly complicates data analysis and interpretation. Deep learning approaches have developed rapidly in the noise suppression field in recent years. In order to eliminate the noise in distributed acoustic sensing–vertical seismic profile data, based on traditional convolution neural network, we add channel attention and spatial attention modules to the network to enhance the feature extraction ability of the network and use extended convolution to increase the receptive field to build a more efficient denoising model. In addition, we use different indicators to evaluate the quality of denoising, including signal‐to‐noise ratio, mean absolute error, kurtosis and skewness. The experimental results show that our method can recover the uplink wave field and downlink wave field, remove horizontal noise, optical system noise, random noise and other noises and improve the overall signal‐to‐noise ratio before and after denoising by 22 dB, reflecting a good ability of denoising and recovering effective signals.
