Use of Shallow Ice Core Measurements to Evaluate and Constrain 1980–1990 Global Reanalyses of Ice Sheet Precipitation Rates

AbstractSea‐level rise (SLR) projections by Earth System Models (ESMs) depend on ice sheet surface mass balances. Accurate, global atmosphere reanalyses would be ideal for providing equilibrated ice sheet model initial conditions in fully coupled ESM simulations. Here we present the first evaluation of 1980–1990 global reanalysis precipitation over Greenland and Antarctica that uses independent observations of net accumulation rates derived from shallow ice cores. Precipitation distributions from both the European Centre for Medium‐Range Weather Forecast's Reanalysis (ERA5) and the Modern‐Era Retrospective Analysis for Research and Applications (MERRA‐2) are highly correlated with contemporaneous co‐located net accumulation rates from Greenland (r2 > 0.95) and West Antarctica (r2 > 0.7). Three other commonly used reanalyses (WFDE5, CRUNCEP, and GSWP3) exhibit significantly weaker correlations on one or both ice sheets. Our findings imply that ESMs should use ERA5 or MERRA‐2 in data‐forced simulations to validate ice sheet model dynamics and precondition firn for SLR projections.

Anodized lamellar Ni-Ni3Si template for electrodeposition of micro-nanostructures

The lamellar Ni-Ni3Si template has the potential for various applications, such as magnetic arrays, layered magnetoelectric materials, electrode materials, and supercapacitors via electrodeposition. However, accurately electrodepositing other materials within the microchannels of the lamellar Ni-Ni3Si template remains a challenge. In this work, the lamellar Ni-Ni3Si template was anodized in 0.1 M oxalic acid (H2C2O4) to achieve accurate deposition of other materials within the microchannels of the lamellar Ni-Ni3Si template. After anodization, the non-anodized and anodized lamellar Ni-Ni3Si templates were subjected to various characterization techniques, including electrochemical impedance spectroscopy, Mott-Schottky analysis, X-ray diffraction and X-ray photoelectron spectroscopy. The study revealed that the optimal anodization potential is 1.2 VSCE, which generated a double-layer passivation film mainly comprised of Ni(OH)2 and SiO2, with a small amount of NiO and Ni2SiO4. Furthermore, cobalt was electrodeposited on non-anodized and anodized lamellar Ni-Ni3Si templates. The results showed that the passive film of the anodized lamellar Ni-Ni3Si template effectively inhibits cobalt nucleation on the surface and sidewalls of the β-Ni3Si sheets and facilitates cobalt deposition within the microchannels. This work provides a novel lamellar metallic template for the electrodeposition of micro-nanostructures.

EXPERIMENTAL DETERMINATION OF THE DRAW BEAD COEFFICIENT OF FRICTION OF CuZn SHEETS IN SHEET METAL FORMING PROCESSES

In sheet metal forming, draw beads are used to limit the flow of sheet metal in specific areas of the stamping die. The value of the coefficient of friction at the draw bead determines achievement of the desired resistance to sheet displacement. This article presents the results of experimental tests for determining the coefficient of friction on a draw bead using a specially developed tribotester. The test material consisted of CuZn37, CuZn30 and CuZn10 brass sheets in various states of hardening. Investigations were carried out with different roughness of the countersamples and sliding speeds. In addition, the tests were carried out under conditions of dry friction and lubrication of the sheet surface with LAN-46 machine oil. The relationships between the process parameters and the value of the coefficient of friction were analysed using the analysis of variance. It was found that the coefficient of friction decreases with increasing mean roughness of the countersamples. Lubrication reduced friction by about 6.2-29.8% depending on the grade of the tested sheet and the sliding speed.

Fe3O4–graphene/polyethylene glycol–SiO2 as a phase change material for thermal energy storage

Renewable energy efficiency can be increased using phase change materials (PCMs). This study has successfully developed PCMs with supporting materials, such as SiO2, Fe3O4, and graphene. Briefly, the synthesis of Fe3O4–Graphene/polyethylene glycol (PEG)–SiO2 begins with the synthesis of Fe3O4–Graphene using the coprecipitation method. Next, Fe3O4–Graphene/PEG–SiO2 nanocomposites are prepared with Fe3O4–Graphene mass varied in a range of 5%–8%. Based on the results, the Eg value of the Fe3O4–Graphene is 1.73 eV. The morphology of Fe3O4–Graphene/PEG–SiO2 shows that Fe3O4 particles stick to the surface of the graphene sheet. The addition of Fe3O4–Graphene mass affects the saturation magnetization value, which increases with an increase in Fe3O4–Graphene within the range of 1.05–2.55 emu/g. In addition, the latent calorific value obtained by differential scanning calorimetry shows that all the samples have a phase transition range within a temperature range of 59.4°C-60.5 °C and a latent calorific value of >100 J/g. Owing to its high latent calorific value, Fe3O4–Graphene/PEG–SiO2 can be applied as a heat-storage material.

Guided axon outgrowth of neurons by molecular gradients generated from femtosecond laser-fabricated micro-holes

ObjectiveTransplantation of scaffold-embedded guided neurons has been reported to increase neuronal regeneration following brain injury. However, precise axonal integration between host and transplant neurons to form functional synapses remains a major problem. Thus, a high-precision tool to actuate neuronal axon outgrowth in real-time conditions is required to attain robust axon regeneration. This study aims to establish a microfluidic platform for precise and real-time axon outgrowth guidance. Methods: A microfluidic device with a 4 μm thick thin-glass sheet as the neuron culture substrate is fabricated. Surface of the glass sheet is chemically modified to facilitate neuron attachment. Femtosecond (fs) laser is used to engrave the glass sheet to achieve micro-holes, where netrin-1 is released for directing the movement of the neuronal axon. Results: Numerical simulation and experimental data demonstrate that netrin-1 gradient is formed after it passes through the micro-hole. The neuronal response results show the outgrowth rate of the axon is significantly increased by netrin-1 gradient. Furthermore, a majority of neuronal axons exhibit guided outgrowth characterized by positive turning angles of axon displacement in the direction of netrin-1 gradients. Conclusion: Integrating fs laser and microfluidic device facilitates controlled and instantaneous axon outgrowth in a non-invasive manner. Significance: The developed real-time microfluidic platform shows potential in the application for on-site neuronal transplantation, which is significant for the treatment of a range of neurological disorders and injuries.

Methods for virus recovery from environmental surfaces to monitor infectious viral contamination

Accurate quantification of infectious contaminants on environmental surfaces, particularly infectious viruses, is essential for contact transmission risk assessment; however, difficulties in recovering viruses from surfaces using swabs complicates this quantification process. Herein, we identified the factors that significantly affected virus recovery rates and developed an ideal swab method that yielded the highest rate of virus recovery. We comprehensively analyzed the effects of swab type (cotton/polyester), swab water content (wet/dry conditions), surface material, and surface area on the rates of viral RNA and infectious virus recovery.The virus recovery rate was significantly lower than the viral RNA recovery rate (P < 0.01), indicating difficulty in the quantification of infectious viruses. The virus recovery rate was significantly higher under wet conditions than that under dry conditions (P < 0.006), and the virus recovery rate obtained using cotton swabs was significantly higher than that using polyester swabs (P < 0.0001). Furthermore, the virus recovery rate had a strong negative correlation (correlation coefficient >0.8) with the target surface area. The maximum surface area where the virus recovery rate was ≥10% (MSA-10%) was identified as the maximum quantifiable area. For influenza virus recovery, MSA-10% on polyvinyl chloride (PVC) sheet, PVC leather, stainless steel, silicone, glass, and polycarbonate surfaces was 66.7, 193, 60.2, 144, 105, and 15.6 cm2, respectively. For feline calicivirus recovery, MSA-10% on PVC sheet, PVC leather, stainless steel, silicone, glass, and polycarbonate surfaces was 210, 111, 2120, 250, 322, and 180 cm2, respectively.The most accurate and ideal method for quantifying infectious viruses on environmental surfaces with the highest recovery rates meets three specifications: “wet conditions,” “the use of cotton swabs,” and “a target surface area of approximately 10 cm2.

Characterization of Formed TRIP1180 Steel Sheet Surface After Stamping with PVD-Coated Tools

The wear tests are conducted on bending punches deposited with PVD CrN and AlTiCrN coatings using the newly proposed progressive die. Then, the surface quality of the formed product is characterized through the surface roughness measurement after forming of TRIP1180 steel sheets. The correlation between the tool wear, in terms of wear depth and roughness and the product surface roughness can be quantitatively analyzed. The results show that the roughness remains comparable to that of the as-received surface before failure occurs, which represents smooth product surface without severe scratches and defects. While micro scratches on the punch surface have no effect on the quality of the product surface, severe fretting wear on the punch surface leads to a deterioration in the surface quality. Once initiated in the stamping process, the wear progresses exponentially within short time. The wear is also characterized as less than the coating thickness, but it results in complete removal of the coating layer. The partially worn punch plows the product surface, causing surface scratches with grooves and ridges, resulting in the roughness of 1.0 μm. In contrast, the surface with completely damaged coatings is extremely rough, with the roughness of 2.0 μm. This study presents the efficient method to evaluate the tool wear progression by indirectly measuring the product surface quality with reliably high precision.Graphical abstract

An automated algorithm to retrieve the location and depth of supraglacial lakes from ICESat-2 ATL03 data

Supraglacial lakes are widespread on the surface of the Antarctic Ice Sheet and Greenland Ice Sheet due to global warming. Estimating the location and depth of supraglacial lakes is critical for evaluating the impact of surface meltwater on ice dynamics. The accuracy of traditional image-based methods is limited, especially when supraglacial lakes are deep. Recently, Ice, Clouds, and land Elevation Satellite-2 data have been used to develop algorithms to measure the depth of supraglacial lakes. The ICESat-2-based methods are currently either semiautomated or sensitive to noise, which makes them less efficient and less accurate in detecting supraglacial lakes. In this study, we develop an automated algorithm for the retrieval of the location and depth of supraglacial lakes using ICESat-2 ATL03 data. We investigated 10 supraglacial lakes as case studies over Antarctica and Greenland (4 lakes on the Amery Ice Shelf, Antarctica and 6 lakes in southwestern Greenland). The results show that our algorithm can detect supraglacial lakes at depths up to 8.25 m. The RMSE for the lake depth retrievals in Antarctica is approximately 0.30 m and that of the lakes in Greenland is approximately 0.32 m. Our algorithm reveals high robustness and accuracy, especially in shallow areas. Additionally, the fully automated algorithm does not require prior knowledge and guarantees efficiency when there is an extensive study area. This result implies that our algorithm has the potential to address large amounts of data and may even be useful to estimate meltwater volumes across the surface of the entire ice sheet.

Non‐similar heat transfer analysis of magnetized flow of Ag‐Mgo/water hybrid nanofluid flow through darcy porous medium

AbstractThis study aims to examine the magnetized flow of Ag–MgO/water hybrid nanofluid over an extending sheet implanted in Darcy porous medium. Thermal radiations, Joule and viscous dissipations are incorporated into energy equation to account for heat transfer. The convective heat flux boundary condition is imposed at sheet surface. Using non‐similar conversions, governing equations are converted to a system of dimensionless partial differential equations (PDEs). These equations are transformed into ordinary ones by using local non‐similar method. MATLAB's bvp4c function is used to numerically simulate the ordinary differential equations (ODEs). The velocity and thermal profiles for positive variation of essential parameters are illustrated graphically. It was concluded that the velocity profile increases for the rising Darcy number. On the other hand, the temperature profile increased for the positive variation of magnetic number, volume fraction, radiation parameter, Eckert number and Biot number while decreasing for all other parameters. The skin friction coefficient and heat transfer rates are thoroughly investigated and findings are reported through tables. It was found that the magnitude of skin friction coefficient rises with an increase in volume fraction, suction and magnetic parameters while the heat transfer is enhanced by increases in Darcy number, suction parameter, radiation parameter, and Biot number. As per the author's knowledge, no work has previously been published on the current model using the local non‐similarity method. This work may provide insight to researchers interested in thermal systems and solar energy harvesting.

Enhancement of visible light organic dyes photodegradation using TiO2 (001)/Graphene oxide nanocomposite

Photodegradation has been considered one of the most promising ways to treat wastewater. In this work, TiO2 (001)/Graphene Oxide (GO) nanocomposite has been successfully synthesized using hydrogen fluoride as a crystal-directing agent towards (001) facets. The nanocomposite was characterized by FTIR, XRD, Raman, HR-TEM, and diffuse reflectance spectra (DRS). Based on the result, the TiO2 (001) was decorated on the surface of the GO sheet with high absorption of visible light. In addition, as-prepared TiO2 (001)/GO nanocomposite provides a synergistic effect by increasing dye degradation activity with 95% and 99% removal rates for the photodegradation of methylene blue and crystal violet dyes, respectively, under LED irradiation for 10 min. The photodegradation kinetics of TiO2 (001)/GO was also successfully modeled and was found to follow the pseudo-first order kinetic. The enhanced photodegradation of the TiO2 (001)/GO nanocomposite attributed to the excellent synergy between TiO2 (001) nanoparticles and GO, which results in the highly efficient photocatalyst for removing organic pollutants in water.

Synthesis of nitrogen-doped reduced graphene oxide/magnesium ferrite/polyaniline composite aerogel as a lightweight, broadband and efficient microwave absorber

The fabrication of graphene-based microwave absorbing materials with low density, small filling ratio, broad bandwidth and strong absorption remains a huge challenge. In this work, nitrogen-doped reduced graphene oxide/magnesium ferrite/polyaniline (NRGO/MgFe2O4/PANI) composite aerogel was synthesized by a three-step method of solvothermal reaction, in situ chemical oxidation polymerization and hydrothermal self-assembly. The results showed that the obtained aerogels had a unique three-dimensional (3D) porous network structure and low bulk density (11.1–13.0 mg cm−3). It was worth noting that in the NRGO/MgFe2O4/PANI ternary composite aerogel, MgFe2O4 coated with a thin PANI layer was anchored on the surface of NRGO sheets. Furthermore, the NRGO/MgFe2O4/PANI ternary composite aerogel showed much better microwave absorbing capacity compared with pure NRGO aerogel and NRGO/MgFe2O4 binary composite aerogel. When the filling ratio was as low as 11.5 wt.%, the obtained ternary composite aerogel exhibited the maximum effective absorption bandwidth of 7.0 GHz at a matching thickness of 2.1 mm, and the minimum reflection loss of -42.9 dB at a thickness of 3.57 mm. Additionally, the probable microwave dissipation mechanism was also elucidated. It was believed that this study would pave the way for the construction of 3D graphene-based composites as lightweight, broadband and efficient microwave absorbents.

Zinc Ions Implantation on the Surface of Commercial Papers for Antibacterial and Antifungal Applications

Recently, the demand for novel food-packaging materials with antimicrobial properties has been increasing drastically. In this report, we attempt to implant zinc ions on the surface of commercial paper sheets by using a hydrothermal method to create hydrozincite nanoflake structures. The formation of the hydrozincite nanostructure was attributed to the adsorption of zinc-ion on the calcite’s surface, a common filler used in commercial paper sheets. The zinc-modified paper sheet (PZn) demonstrated a high efficiency to inhibit C. albicans and E. coli growth. It is attributed to the release of the Zn2+ ions into the acidic microbial medium. Along with the eco-friendliness, and biocompatible properties of the paper substrate, the PZn demonstrated a promising application in food packing.

A label-free aptasensor for colorimetric detection of food toxin: Mediation of catalytically active gold nanozymes and smartphone imaging strategy

A portable colorimetric aptasensor was developed on the surface of a plastic sheet for on-site detection of acrylamide. The mechanism of aptasensor is based on the disruption of the aptamer complex with its complementary strand on the sensing zone, and subsequently, the catalytic activity of gold nanoparticles (AuNPs) for the reduction process of 4-nitrophenol (4-NP) in the presence of sodium borohydride (NaBH4). A yellow-to-colorless change of the sample solution revealed the target presence, easily discernible by the naked eye. The acrylamide quantification was accomplished using the smartphone imaging readout technique. The aptasensor detected the acrylamide concentration in the range of 0.01–500 nmol L−1 with a detection limit of 0.0024 nmol L−1. Coffee, potato chips, bread, and lake water samples were successfully analyzed by the aptasensor for their acrylamide content. The introduced aptasensor can pave a facile, cost-effective, portable, and user-friendly sensing tool for food safety control and environmental monitoring.

On-line heating rolling behavior of Mg9999 sheets under large single pass reduction

Pure magnesium foil has a great potential for rechargeable magnesium battery anode application, the formation of edge crack and break during Mg sheet rolling highly decreases the yield and thus increase the cost. In this paper, pure magnesium sheets of different thicknesses (0.3 mm, 0.4 mm, 0.5 mm and 0.6 mm) were prepared from 1 mm pure magnesium sheets by on-line heating rolling in a single pass. The edge cracking and breaking behavior of pure magnesium sheets were characterized by scanning electron microscope (SEM), X-ray diffractometer (XRD), electron backscatter diffractometer (EBSD), energy dispersive spectroscopy (EDS) and laser scanning confocal fluorescence microscope (LSCM). The results show that the number of edge cracks of pure magnesium sheets increases with the increase of rolling reduction. As the rolling reduction increases to 70%, due to the severe edge crack of 0.3 mm thick sheet and the formation of grooves on the magnesium sheet surface, the breaking of pure magnesium sheets occurs. The mechanism of edge cracking and breaking of ultra-thin pure magnesium rolled sheet is discussed.

Characterising the ice sheet surface in Northeast Greenland using Sentinel-1 SAR data

AbstractOver half of the recent mass loss from the Greenland ice sheet, and its associated contribution to global sea level rise, can be attributed to increased surface meltwater runoff, with the remainder a result of dynamical processes such as calving and ice discharge. It is therefore important to quantify the distribution of melting on the ice sheet if we are to adequately understand past ice sheet change and make predictions for the future. In this article, we present a novel semi-empirical approach for characterising ice sheet surface conditions using high-resolution synthetic aperture radar (SAR) backscatter data from the Sentinel-1 satellite. We apply a state-space model to nine sites within North-East Greenland to identify changes in SAR backscatter, and we attribute these to different surface types with reference to optical satellite imagery and meteorological data. A set of decision-making rules for labelling ice sheet melting states are determined based on this analysis and subsequently applied to previously unseen sites. We show that our method performs well in (1) recognising some of the ice sheet surface types such as snow and dark ice and (2) determining whether the surface is melting or not melting. Sentinel-1 SAR data are of high spatial resolution; thus, in developing a method to identify the state of the surface from these data, we improve our capability to understand the variation of ice sheet melting across time and space.

Computational method for energy transport of MHD nanofluids flow near non-aligned stagnation point with non-linear thermal radiation and interface slip

Haemodialysis, nuclear reactors, cooling and heating systems, and heat exchangers are glimpses of applications where thermal problems are considered as a fundamental for flow over aligned stagnation points with heat and mass transfer components. The purpose of this study is to present steady dual solutions for non-aligned stagnation point flow of nanofluid over a linearly contracting/expanding surface under temperature and velocity slips. The mathematical model is established using boundary layer assumption. The authors acknowledge from prior investigations and studies that the non-aligned stagnation point flow across a contracting/expanding surface is highly rare in the field of engineering and fluid dynamics research. In the backdrop of non-linear thermal radiation, the problem of oblique hydromagnetic stagnation point flow of an electrically conducting optically dense viscous incompressible nanofluid across a convectively heated stretching sheet is formulated. The effects of Brownian motion and thermophoresis are incorporated into the nanofluid model. With the use of appropriate similarity transformations, the governing nonlinear partial differential equations for momentum, energy, and nanoparticle concentration are converted into a set of nonlinear ordinary differential equations. Using the BVP4c approach, the modified equations are numerically solved. It is discovered that when the strength of the magnetic field increases, the non-alignment of the re-attachment point on the sheet surface becomes less pronounced. The thickness of the thermal boundary layer grows as the magnetic and Biot parameters expand. The extent of the skin friction factor ascends with increasing magnetic field and suction variable inputs. The heat transfer rate detract with radiative parameter.

Molecular dynamics simulation and experimental study on formation mechanism of micro-hole and cracks in nano-imprinting diamond

Diamond nano-imprint microhole forming technology is a new type of microhole forming method. However, there will always be some unqualified microholes and cracks in the manufacture of microholes. In order to obtain better microhole quality, it is crucial to study the mechanism of microhole formation. In this paper, the indentation process of single crystal copper by a conical indenter is simulated by molecular dynamics. After the indentation is completed, microholes and cracks will form on the surface of the copper sheet. Dislocation analysis will be conducted on the microholes and surrounding cracks, and then the microstructure and morphology will be demonstrated to explain the formation mechanism of microholes and cracks. The influence of different indentation speeds and temperatures on the energy change of the system is discussed. In addition, this article established an experimental device for diamond indentation of copper sheets, and conducted indentation microholes experiments to observe microholes and cracks through scanning electron microscopy. The results show that when the diamond indenter is pressed down, the number of atoms in contact between the diamond indenter particles and the copper surface gradually increases, causing local stress concentration and the formation of new dislocations. Among them, 1/6&lt;112&gt; shockley dislocation is the main dislocation type. When the strain energy stored in the lattice increases beyond a certain value, the lattice structure of the copper atoms in the contact area is broken, resulting in internal defects, gradually forming microholes and surrounding cracks. The increase in the imprinting speed will accelerate the plastic deformation of the copper sheet. This paper reveals the mechanism of the formation of microholes and cracks, laying the foundation for high-quality micropore manufacturing.

Kinetic Analysis on Hydrogen Entry into Steel in Aqueous Solutions by Alternating Current Method

Degradation of steels due to the hydrogen embrittlement, which is related to the hydrogen penetration reaction (HPR) into steel, is a serious problem from the standpoint of infrastructure preservation. A Devanathan-Stachurski permeation technique [1, 2] is a well-known method to determine a hydrogen penetration rate in metals. In this technique, two independent electrochemical cells are arranged on right across two surfaces of thin metal sheet and anodic and cathodic polarizations can be performed with each cell using the three-electrode system. The hydrogen penetration rate can be evaluated by measuring the oxidation current of hydrogen atoms diffused in the metal sheet at the anode side. The electrochemical impedance spectroscopy (EIS) was used for electrochemical measurement with the Devanathan cell to investigate HPR mechanisms because the time constants of hydrogen evolution and entry can be discriminated [3-5]. In this study, we used a complex hydrogen penetration ratio (CHPR), which is a transfer function related to hydrogen entry and diffusion in metal sheet, with the Devanathan cell to investigate kinetics of hydrogen entry into metals. The CHPRs of carbon steel sheet immersed in aqueous solution of different pH’s were measured in this study. The rate constant of hydrogen entry was determined by comparing experimental results with the simulated ones according to the theoretical equation, and influence of pH on hydrogen entry was discussed.

Rolling preparation process and interface toughening mechanism of Al/CFRTP/Al composite laminates

AbstractIn this study, a highly efficient method for preparing Al/CFRTP/Al composite laminates by roller preparation was proposed. Three different surface treatments, namely, anodic oxidation, laser texture and surface modification, were used to improve the strength of the metal‐fiber interface. Results show that composite laminates can be prepared efficiently by using reasonable roll pressing technology. The composite laminates with a thickness of 3 mm has good shear strength when the reduction amount is 0.02 mm. Laser texturing increases the contact area at the laminate interface. The surface roughness of Al alloy sheet is improved after laser texture. Moreover, the matrix in the fiber layer of the laminate can be embedded in the gullies formed by the laser texture to form a mechanical interlocking structure. The shear strength of the laminates was further increased when the laser scanning spacing was 2 mm. The highest shear strength of the laminate is 52.4 MPa after using a coupling agent to modify the surface of the Al alloy sheet. X‐ray photoelectron spectroscopy analysis showed that a new chemical bond was generated at the interface between CFRTP and the Al alloy sheet modified with silane coupling agent, thereby forming a molecular bridge among different materials. Mechanical interlocking structure and the generation of new chemical bonds cause the interface to need to absorb more energy during the failure process, which is conducive to the improvement of the interface strength.Highlights Propose roller pressing to prepare Al/CFRTP/Al composite laminates. Effect of laser texture of the laminates interface is clarified. Mechanism of coupling agents at the interface has been elucidated. Efficient preparation of thermoplastic fiber metal laminates has been achieved.
