Abstract
The monitoring of methane emission is helpful for reducing the concentration of atmospheric greenhouse gases. A preliminary methane emission study of typical coalbed methane production areas based on multi-satellites remote sensing data was proposed. Methane monitoring for typical coalbed methane production areas in Shanxi Province, methane anomaly analysis, associated gas flaring identification as well as emission estimation were carried out, using Sentinel-5P TROPOMI (TROPOspheric Monitoring Instrument) CH4 data, Sentinel-2 false color images and VIIRS (Visible Infrared Imaging Radiometer Suite) active fire data. The research showed that typical coalbed methane production areas in Shanxi Province were featured with high CH4 concentration in the southeast and low concentration in the northwest. The maximum methane anomaly of about 80 ppb was discovered and the emission rate was estimated to be approximately 20 t/h-23 t/h for the identified associated gas flaring location. The estimation was consistent with the results from PRISMA data for the Shanxi coal mining region. The research demonstrated the capability of satellite observation to support the coalbed methane production emission source identification from space and indicated the method provided was favorable for methane anomaly analysis, emission identification as well as emission rate estimation for coalbed methane production areas.

Published: January 2024

Abstract
Grouting is an effective method to enhance the bearing capacity of in-service pile foundations. The effect of optimizing grouting parameters for in-service pile foundation grouting reinforcement was verified through static load tests. The field tests of the pileless stratum show that the cement-sodium silicate slurry is more favourable for increasing the grouting pressure and more convenient to control the slurry diffusion than cement slurry. The grouting parameters of cement-sodium silicate slurry were determined according to the maximum grouting pressure and quantity. The slurry grouting parameters were cement slurry 1.6g/cm3 and cement slurry to sodium silicate ratio 2.29:1. Moreover, the effective range of segmental localized grouting reinforcement was detected by the resistivity method and in-situ standard penetration test, and the grouting position should be less than 2m from the side of the in-service pile foundation. Finally, it is found that pile side grouting can improve the bearing capacity of in-service pile foundation by 98% through static load test. The research results have reference value and guiding significance for the design and effect detection of pile foundation grouting reinforcement.

Authors: Chen S C , Yu X M , Shi X L 
Published: January 2024

Abstract
The method of machine test was used in this study to analyze the influence of carbon fiber content and voltage strength on the impact resistance of carbon fiber concrete by recording the number of impacts to carbon fiber concrete fracture failure. The results show that as the volume content of carbon fiber increases, the impact resistance to the specimens increases first and then decreases. The impact resistance reaches maximum that the content of 0.24 %, and the calculation formula for the number of impacts to concrete beams under different carbon fiber content in the test is obtained. However, the impact resistance is in a state of overall reduction under the action of voltage, and the reduction range is obvious, indicating that the voltage effect has a negative impact on the impact resistance of carbon fiber concrete.

Authors: Wang Yaoxin , Zhang Li , Li Lei 
Published: January 2024

Abstract
SLM (Selective Laser Melting) Inconel718 alloy has good corrosion resistance, oxidation resistance and fatigue resistance, which is an indispensable and important material in industrial fields such as energy power, aerospace and nuclear power. In this paper, the fatigue damage evolution behavior of SLM Inconel718 alloy under different heat treatment is studied by the MTS fatigue testing machine and DIC (digital image correlation method). The results show that the fatigue evolution of SLM Inconel718 alloy changes slowly in the initial stage of fatigue evolution. When the damage factor reaches the critical value, alloy begins to enter the rapid damage stage. In the steady stage, SLM Inconel718 alloy has small damage accumulation. In the rapid damage stage, the damage degree of SLM Inconel718 alloy increases and the damage accumulates rapidly. The critical damage factor can effectively distinguish these two stages, and the critical damage factor under different heat treatment shows: AT2 > AT1 > AT3.
Study on asphalt damage characteristics in cold area with large temperature gradient
Authors: Tan Tianhua , Ke Wenhao , Wang Zhengjun 
Published: January 2024

Abstract
The primary cause of the asphalt pavement disease in this region is the large temperature differential and high ultraviolet (UV) radiation that characterize this frigid environment. This study assessed the ductility, penetration, softening point, and rheological properties of several asphalts under various freeze-thaw cycles and UV aging conditions. Additionally, the damage characteristics of asphalt in cold and large temperature gradient areas were examined. The findings indicate that the freeze-thaw cycle significantly affects the asphalt’s low-temperature crack resistance but has no discernible effect on the material’s traditional performance or high-temperature rutting resistance. Asphalt’s resistance to low temperature cracking is ranked according to the impacts of UV radiation and the freeze-thaw cycle: 80/100 pen grade asphalt, 100/120 pen grade asphalt, SBS modified asphalt, and SBR modified asphalt. The impact of UV radiation and the freeze-thaw cycle on the high temperature performance of asphalt is categorized into four categories: SBR modified asphalt, SBS modified asphalt, 80/100 pen grade asphalt, and 100/120 pen grade asphalt.

Boosting corrosion resistance of carbonyl iron via silicon encapsulation

Published: January 2024

Abstract
Carbonyl iron is prone to electrochemical corrosion in environments such as salt spray, marine, or atmospheric conditions, leading to a decline in operational performance or even failure. In this study, tetraethyl orthosilicate (TEOS) and polydimethylsiloxane (PDMS) were used as raw materials, the silicon-encapsulated carbonyl iron composites were synthesized by dehydration condensation of silicon hydroxyl group of TEOS and terminal hydroxyl group of PDMS using a modified sol-gel method, aiming to bolster their corrosion resistance properties. The results of electrochemical experiments demonstrate that the CI@SiO2@PDMS composite exhibits excellent corrosion resistance. The corrosion potential is shifted in a positive direction to -0.11, accompanied by a significant reduction in the corrosion current by three orders of magnitude, down to 3 × 107. Furthermore, the electrochemical impedance modulus reaches a value of 1.3 × 105 Ω cm2, a magnitude that is nearly three orders of magnitude superior to that exhibited by the original iron powder. Additionally, the contact angle test reveals that the composite material possesses favorable hydrophobic properties. Therefore, the improved corrosion resistance observed in the composites can be ascribed to the inhibitory barrier effect of the modified layer and the hydrophobicity, which hinder the approach of corrosive ions.

Published: January 2024

Abstract
Here we present an experimental implementation of the fluorescence concatless method for the temperature determination of YAl3(BO3)4 crystals doped with Yb3+ ions. We have investigated the anti-Stokes fluorescence spectra of the crystal in the 900-1020 nm spectral range. The spectra have been measured while heating the crystal in the temperature range from 290 to 573 K. The increase of crystal temperature results in an enhancement of the relative fluorescence intensity in the short-wavelength region. The linear dependencies obtained can be used as a calibration function for contactless temperature measurements of YAl3(BO3)4 laser crystals doped with Yb3+ ions.

Authors: Wu Ling , Zhang Yingqiang 
Published: January 2024

Abstract
The influence of reactive diluents on the exothermic effect in the curing of ultraviolet coatings were examined, and their effects on the adhesion, gloss, anti-friction, flexibility, and water contact angle of ultraviolet coating films were analyzed in depth. The results showed that the screening of suitable reactive diluents was beneficial to balance the multiple properties of ultraviolet coatings. Among the reactive diluents examined, the samples prepared with monofunctional reactive diluents had higher curing exothermicity. The Ultraviolet coating films prepared with LuCure645 and HPMA had better adhesion. The ultraviolet-cured films prepared with monofunctional reactive diluents all had better flexibility, while the ultraviolet-cured films prepared with bifunctional reactive diluents had better anti-friction.

Abstract
Titanium dioxide (TiO2) is widely used as a photocatalyst due to its advantages of low cost, photostability, strong oxidation capability, and high resistance to chemical and environmental sustainability. However, TiO2 has drawbacks of a wide band gap and fast recombination of electron-hole pairs which reduces its photocatalytic efficiency. Therefore, doping TiO2 with metal ions can be considered to overcome these issues. In this study, Ni-doped TiO2 with different doping concentrations (1, 3, 5, and 7 wt%) have been successfully prepared by the sol-gel method. All samples were characterized using field emissions scanning electron microscopy (FESEM), Energy dispersion X-ray (EDX), X-ray diffraction (XRD), and Fourier transform infrared (FTIR). The surface morphology of all samples examined by FESEM showed an agglomeration of spherical shape. In addition, EDX confirms the presence of Ti and O atoms in undoped TiO2 sample and the presence of Ni atoms in Ni-doped TiO2 samples. XRD analysis showed the structural phase of anatase was observed in all samples. The crystallite size of TiO2 decreased significantly from 16.058 nm to 14.926 nm when it was doped with 5 wt% of Ni. The specific surface area (SSA) is indirectly proportional to the crystallite size with the highest value of SSA found to be 95.032 m2.g−1 for 5wt% Ni doping. FTIR presents Ti-O-Ti and OH bonds with a small shift to higher wavenumbers. These results indicated that Ni has significant influences on the morphological and structural properties of TiO2 with the optimum doping concentration of 5 wt%.

Published: January 2024

Abstract
Modeling and control methods for stiffness-tunable soft robots (STSRs) have received less attention compared to standard soft robots. A major challenge in controlling STSRs is their infinite degrees of freedom, similar to standard soft robots. In this paper, demonstrate a novel STSR by combing a soft-rigid hybrid spine-mimicking actuator with a stiffness-tunable module. Additionally, we introduce a new kinematic and dynamic modeling methodology for the proposed STSR. Based on the STSR characteristics, we model it as a series of PRP segments, each composed of two prismatic joints(P) and one revolute joint(R). This method is simpler, more generalizable, and more computationally efficient than existing approaches. We also design a multi-input multi-output (MIMO) controller that directly adjusts the pressure of the STSR’s three pneumatic chambers to precisely control its posture. Both the novel modeling methodology and MIMO control system are implemented and validated on the proposed STSR prototype.

Published: January 2024

Abstract
Scaffold development approaches using autologous sources for tissue repair are of great importance in obtaining bio-active/-compatible constructs. Platelet-rich plasma (PRP) containing various growth factors and platelet lysate (PL) derived from PRP are autologous products that have the potential to accelerate the tissue repair response by inducing a transient inflammatory event. Considering the regenerative capacity of PRP and PL, PRP/PL-based scaffolds are thought to hold great promise for tissue engineering as a natural source of autologous growth factors and a provider of mechanical support for cells. Here, a bio-mineralized PRP-based scaffold was developed using oxidized dextran (OD) and evaluated for future application in bone tissue engineering. Prepared PL/OD scaffolds were incubated in simulated body fluid (SBF) for 7, 14 and 21 d periods. Mineralized PL/OD scaffolds were characterized using Fourier transform infrared spectroscopy, x-ray diffraction spectroscopy, scanning electron microscopy (SEM), thermogravimetric analysis, porosity and compression tests. SEM and energy-dispersive x-ray spectroscopy analyses revealed mineral accumulation on the PL/OD scaffold as a result of SBF incubation. In vitro cytotoxicity and in vitro hemolysis tests revealed that the scaffolds were non-toxic and hemocompatible. Additionally, human osteoblasts (hOBs) exhibited good attachment and spreading behavior on the scaffolds and maintained their viability throughout the culture period. The alkaline phosphatase activity assay and calcium release results revealed that PL/OD scaffolds preserved the osteogenic properties of hOBs. Overall, findings suggest that mineralized PL/OD scaffold may be a promising scaffold for bone tissue engineering.

Abstract
Posterior capsule opacification (PCO) is a main complication after cataract surgery and intraocular lens (IOLs) implantation and is attributed to residual lens epithelial cells (LECs) migrating to the IOL surface and posterior capsules. IOL surface modification has been a newly-developing research filed in recent years; however, the applicability and economical acquisition of modified materials remain unsolved. In this study, we first applied a metal-polyphenolic network coating with a self-assembly technique on the IOL surface by using tannic acid (TA) combined with AlCl3, which are easily acquire and applying on the IOL surface to solve the IOL transmittance affair. Using wound healing and Transwell assay to verify AZD0364 inhibits cell migration (
P
< 0.05), the lipopolysaccharide-induced macrophage inflammation model to verify pterostilbene (PTE) inhibits the inflammatory reaction (
P
< 0.01). By optimizes its self-assembly coating parameters and calculating its drug release kinetics, we successfully loaded these two drugs on the coating, named TA (AZD0364/PTE) IOL. Its surface morphology characteristics were analyzed by scanning electron microscope, x-ray photoelectron spectrometer and water contact angle. The optical performance was carefully investigated by optical instruments and equipment (n= 3). The in vitro results showed that TA (AZD0364/PTE) IOL can significantly inhibit cell adhesion and acute inflammation (n= 3,
P
< 0.0001). Importantly, after in vivo implantation for 28 d with eight rabbits PCO models in two groups, the TA (AZD0364/PTE) IOL group maintained clear refracting media and decreased the inflammatory reaction compared with the original IOL group (
P
< 0.05). This study provides a new applicable and economical strategy for preventing PCO and offers a reference for the next generation of IOLs that benefit cataract patients.
