Authors: Dai Lihui , Shan Yu , Liu Jiayun , An Fengjiang , Wu Cheng 
Published: January 2024

Abstract
This paper presents uniaxial tensile loading tests on polyurea to analyze the characteristics of stress-strain behavior under a high strain rate. The results verify the process of stress-strain behavior, which shows the non-linear and rate-dependent process of stress-strain behavior, should be divided into several stages: a linear elastic stage, a non-linear transitional yielding stage and a hardening failure stage. Three different constitutive models are used to predict the behavior of material. By fitting the test datas and calculating the Root Mean Square Error (RMSE), the visco-hyperelastic model is more appropriate to represent the mechanical behavior of polyurea under high strain rate. It also shows the material would transform from a rubber-like material to a glassy-like material under strain rates of 600s

Abstract
Metal-organic frameworks (MOFs) derived catalysts with improved recovery and reusability are challenging in peroxymonosulfate (PMS) activation. Herein, a ZIF-67/graphene aerogel (Z-GA) heterostructure was rationally constructed via in situ growth method based on the synergistic effect: Co
x+ stabilized the PMS activation capacity and GA provided high opportunity for radicals and contaminants contact. The as-prepared Z-GA/PMS system exhibited outstanding performance for the tetracycline hydrochloride (TC) removal, good pH-stability ranging from 5.0 to 9.0 and excellent anti-interference capability. The quenching experiment and EPR tests co-proved the significant roles of reactive SO4
•- and 1O2 species in the TC degradation process. In addition, several contaminants were selected to certify the superiority of the Z-GA3/PMS and multiple water sources were employed to demonstrate the universality in the complicated water environment. This pioneering work demonstrated the feasibility of Z-GA/PMS system for effluent disposal.

Published: January 2024

Abstract
Aerobic fermentation is a key link in the regeneration system of cattle mattress material. In this paper, the three-dimensional structure of the aerobic fermentation drum was designed using SolidWorks software, and the discrete element model of the aerobic fermentation temperature field was established using Fluent software. The simulation analysis shows that the temperature inside the aerobic fermentation drum can be maintained stably between 60°C and 75°C by reasonably adjusting the feed rate, ventilation volume and drum speed, and the fermentation time of the regenerated bedding material can be adjusted from 8 to 22 hours, which can achieve continuous and stable feed and discharge production, indicating the feasibility and effectiveness of the aerobic fermentation process. When the feed rate is 2 m3/h, the ventilation rate is 180 m3/h and the drum speed is 0.3 r/min, a rated production rate of 48 m3/day can be met. The research has important reference value for aerobic fermentation process control and system design of cattle mattress material regeneration system.

Abstract
It is of great practical significance for comprehensively promoting the green development of agriculture to explore practical products for preventing and controlling nitrogen and phosphorus leaching. In this study, PVC soil column experiments and field experiments were used to evaluate the interception effect of soil amendments produced by green wastes on nitrogen and phosphorus leaching. The pH value, EC value, the nutrient contents of ammonium nitrogen (NH4
+-N), nitrate nitrogen (NO3
−-N), total nitrogen (TN), and available phosphorus (AP) in different soil layers and leaching solution were determined, and the interception effects of soil amendment on nitrogen and phosphorus leaching were comprehensively evaluated. The results showed that the soil amendments of green waste had significant inhibition and control effects on the leaching of NH4
+-N, NO3
−-N, APs, and TN. The interception mechanism of the soil amendments of green waste on nitrogen and phosphorus leaching was mainly to absorb a large amount of leaching solution and various forms of nitrogen and phosphorus nutrients. The results also showed that the soil amendment of green waste had a certain nutrient content and buffering effect on acid and alkali and the main form of nitrogen leaching was NO3
−-N. This study provides a theoretical basis for the development of cheap and effective physical products to prevent and control nitrogen and phosphorus leaching from farmland.
Successful Water Quality Improvement Practices of a Campus’s River in Ningbo Based on Water Replenishment and Circulation Since Year 2017
Authors: Xie Honglei , Cheng Jianhua , He Yong , Hu Haolei 
Published: January 2024

Abstract
Rivers play a critical role in regional water quality, but from time to time concentration of surface water pollutants can easily exceed both national and local water standards. This study debates the feasibility and effectiveness of utilizing the natural treatment potential of flowing river water by replenishing treated sewage effluent and forced circulating. The research combines field experiments and laboratory analyses to assess the impact of this approach on water quality. Theoretical simulation with one-dimension modeling recommended by China’s national standard of “Code of Practice for Computation on Allowable Permitted Assimilative Capacity of Water Bodies” (GB/T 25173-2010) indicates that the target campus river water’s cycle flowing contributes to the further removal of key pollutants from treated sewage, resulting in the improvement of campus river’s water quality downstream along its forced circulation. NH3-N and CODMn levels of the campus’s river water were notably reduced and met the planning water qualities as expected.

Published: January 2024

Abstract
This study aims to examine how the mesoscale atmospheric forecast model WRF impacts the accuracy of wind field simulation in the central and western regions of Hainan. Nine different physical parameterization schemes were designed and evaluated using the historical reanalysis dataset from the European Centre for Medium-Range Weather Forecasts (ECMWF). The evaluation was based on the first 7 days of January and July 2022, and the correlation coefficients successfully passed the 99% confidence level test. The results show that the optimal parameterization combination scheme of microphysical parameter WSM3 + boundary layer YSU + cumulus parameter GF in winter has better wind field simulation performance for Dongfang and Changjiang stations. The simulation results during summer were found to be slightly larger than the observed data. The optimal parameterization scheme was determined to be WSM3 + boundary layer UW + cumulus GF, with wind speed correlation coefficient higher than 0.7 for all three stations. The dominant wind direction was found to be consistent with the observed data, indicating a better wind field simulation effect. The study suggests that using the optimal combination of parameterization schemes can enhance the accuracy of wind simulation near the Changjiang nuclear power plant when using the WRF model.
Simulation of the effect of continuous casting tundish filter on removing inclusions in steel
Authors: Liu Yang , Chu Rensheng , Li Xin , Hao Ning , Wang Weihua 
Published: January 2024

Abstract
The control of inclusions in clean steel production is one of the key processes and a key factor determining the quality of high-end steel materials. The inhomogeneous hydrodynamic equations have been numerically solved to obtain a transient and multiphase field inside the caster tundish with filter to predict the inclusion movement track and percentage of inclusion removal during continuous casting process. The simulation result is validated with the samples taken during casting continuous process in X steelworks. The method of bulk-sample-electrolysis is taken to analyze the percentage of inclusion removal of the samples. The results imply: the inclusions through the filter are influenced on velocity and separated from liquid steel with high turbulence. Thus the inclusions’ residence time in tundish is prolonged, which causes the probability of inclusion removal increasing. The fluctuations on percentage of inclusion removal are found when the diameter of inclusions is less than 80μm. However, the fluctuation is not so severely for the inclusions of more than 100μm. The percentage of inclusion in tundish as 100 tones remaining in ladle is larger than that as 200 tones remaining in ladle. The percentage of inclusion removal is proportional to time. The filter can reduce the irregular inclusions to improve the quality of product.
A new tensile creep model for predicting long-term creep strengths with short-term test data for creep resistant alloys
Authors: Qiu Y Y , Dong Z , Song X L , Xiang Z D 
Published: January 2024

Abstract
The difficulties in using the conventional Norton creep model to rationalise short-term creep data and to subsequently predict long-term creep rupture strengths for creep resistant alloys are presented and analysed. The results of this study show that these difficulties can be resolved if a new tensile creep model that integrates the tensile strength at creep temperature is applied to rationalise the short-term creep data. This is illustrated with the creep and tensile strength data measured for a grade of Ni-based superalloy. Based on this new tensile creep model, the activation energy of creep determined is independent of stress and the stress exponent is not influenced by temperature. Consequently, the model constants obtained from the short-term creep data can be applied together with the Monkman-Grant relationship to make the long-term creep rupture strength predictions at different temperatures. The factors affecting the reliability of the predictions made by this method are also analysed.
Comparative study of the influence of charge shapes on the distribution of blast pressure on a structural unit
Authors: Punnappilly Sreekumar , Baskar K 
Published: January 2024

Abstract
Since limited research results are available in the area of blast wave interactions with structural surfaces, a comparative study is undertaken to ascertain the interaction effects of blast waves generated by exploding spherical and cylindrical charges on the surface of a concrete structural unit. The effective blast pressure experienced by a concrete unit is evaluated and its distribution across the front face is studied here for two distinct charge shapes, namely spherical and cylindrical. The finite element analysis is carried out for nine different scaled distances. Random forests algorithm was utilized to analyze the 450 observations to evaluate the results and build predictive models. The best models were selected based on standard performance indicators. For cylindrical charges, the aspect ratio was also factored in the analysis. The distribution of effective pressure indicates unique patterns for the two different charge shapes in the graphical comparison. The effective pressures caused by the cylindrical charge shape for the specific aspect ratios considered here are lower by 84 % on average compared to the effect caused by a spherical charge, which results from the distinct characteristics of blast waves generated by the explosion of cylindrical charges.
Up-conversion photoluminescence of transition metal chalcogenide monolayers under high pressure
Authors: Li Y Y , Tang T H 
Published: January 2024

Abstract
The up-conversion photoluminescence (UPL) phenomena of transition metal chalcogenides (TMDCs) materials have been studied in the recent years, but high-pressure tuning effect remains unclear. In this work, we applied pressure to the monolayer WS2 by Diamond Anvil Cell (DAC). The PL and UPL of monolayer WS2 under ambient pressure and tuning from 0.96GPa to 4.48GPa were investigated using various excitation energies. We found that with the increase of applied pressure, the intensity of UPL decreased dramatically. Under the same pressure, the peak of UPL is shifted compared with that of normal PL. This tuning is promising for realizing photodetection by using of the up-conversion process.

Authors: Wang W , Wei B , Shi G P , Pang Z 
Published: January 2024

Abstract
Ti3SiC2 is the most typical 312 MAX phase, which has attracted more attentions in many fields. In this paper, the (0001) plane of Ti3SiC2 was built. The adsorption energy and diffusion path of oxygen atom at different sites were calculated by first principles. There are three different adsorption sites for oxygen atom on Ti3SiC2 (0001) surface. By calculating the adsorption energy of the three adsorption sites, it was found that the adsorption energy of the oxygen atom at the center site is the lowest. The diffusion path of the oxygen atom was simulated and showed that oxygen atom located at the center of Ti-Si tetrahedron after the diffusion into the bulk phase. The effects of solid solution elements on the diffusion activation energy of oxygen atoms were calculated. suggesting that the solid solution of V, Mo and W will greatly increase the energy barrier, thus preventing the inward diffusion of oxygen atoms.

Authors: Rudyi Semyon , Shcherbinin Dmitrii , Rybin Vadim , Ivanov Andrei 
Published: January 2024

Abstract
In the present work, we propose a rapid analysis of the trapped ion dynamics regimes. The Hoeffding’s Independence Test (HIT) mapping technique has been considered as a promising approach for the detection of dynamic regimes. As a model problem, we have applied the proposed method to ion dynamics in an octupole ion trap. We compare the results of HIT mapping with the results of direct calculation of the non-trivial Lyapunov exponent. The HIT mapping result well agree with a Lyapunov exponent mapping. The computational time for plotting the HIT maps was significantly less than the computational time for plotting the Lyapunov exponent maps.
Hot corrosion behaviours of the LaYbZr2O7 thermal barrier coatings in different corrosive salts
Authors: Yan Kai , Xiang Yong , Lei Yuehua , Yu Haiyuan , Sun Jian , Ren Jiarui 
Published: January 2024

Abstract
In this study, the LaYbZr2O7 (LYZ) thermal barrier coatings (TBCs) were deposited by air plasma spray (APS) and were subjected to hot corrosion in the single V2O5 salts and the mixture of V2O5+Na2SO4 with different Na2SO4 content at 1000 °C. The reaction mechanism and corrosion layer evolution of the LYZ coating in different corrosive molten were comparatively investigated. After hot corrosion in the single V2O5 salt, the surface of the LYZ coating develops a dense corrosion layer, which could keep structural integrity with the extension of exposure time, indicating the LYZ coating showed higher resistance to the V2O5 corrosion. However, the dense layer failed to form on the surface of the LYZ coating in the V2O5+Na2SO4 mixed salts. With the increase of Na2SO4 content, the corrosion products formed on the surface of the LYZ coating gradually decreased, and the corrosion layer disappeared. The dominant reason for the difference was that the addition of Na2SO4 resulted in the acidity reduction of the mixed salts, which eventually caused a decrease in the corrosion rate. Compared with the single V2O5, the V2O5+Na2SO4 mixed salts showed higher penetration ability in the LYZ coating and could be more damaging.

Abstract
Biomaterial scaffolds boost tissue repair and regeneration by providing physical support, delivering biological signals and/or cells, and recruiting endogenous cells to facilitate tissue-material integration and remodeling. Foreign body response (FBR), an innate immune response that occurs immediately after biomaterial implantation, is a critical factor in determining the biological outcomes of biomaterial scaffolds. Electrospinning is of great simplicity and cost-effectiveness to produce nanofiber scaffolds with well-defined physicochemical properties and has been used in a variety of regenerative medicine applications in preclinical trials and clinical practice. A deep understanding of causal factors between material properties and FBR of host tissues is beneficial to the optimal design of electrospun scaffolds with favorable immunomodulatory properties. We herein prepared and characterized three electrospun scaffolds with distinct fiber configurations and investigated their effects on FBR in terms of immune cell-material interactions and host responses. Our results show that electrospun yarn scaffold results in greater cellular immune reactions and elevated FBR in in vivo assessments. Although the yarn scaffold showed aligned fiber bundles, it failed to induce cell elongation of macrophages due to its rough surface and porous grooves between yarns. In contrast, the aligned scaffold showed reduced FBR compared to the yarn scaffold, indicating a smooth surface is also a contributor to the immunomodulatory effects of the aligned scaffold. Our study suggests that balanced porousness and smooth surface of aligned fibers or yarns should be the key design parameters of electrospun scaffolds to modulate host response in vivo.

Published: January 2024

Abstract
Regeneration of damaged urethral tissue remains a major challenge in the field of lower urinary tract reconstruction. To address this issue, various synthetic and natural biodegradable biomaterials are currently being explored for the fabrication of scaffolds that promote urethral regeneration and healing. In this study, we present an approach to fabricate a trilayer hybrid scaffold comprising a central layer of poly(lactic acid) (PLA) between two layers of chitosan. The chitosan/PLA/chitosan (CPC) scaffolds were fabricated by a sequential electrospinning process and their properties were evaluated for their suitability for urethral tissue engineering. The physical and biological properties of the CPC scaffolds were evaluated in comparison to electrospun PLA scaffolds and acellular dermis (Alloderm) as controls for a synthetic and a natural scaffold, respectively. Compared to the controls, the CPC scaffolds exhibited higher elastic modulus and ultimate tensile strength, while maintaining extensibility and suture retention strength appropriate for clinical use. The CPC scaffolds displayed significant hydrophilicity, which was associated with a higher water absorption capacity of the chitosan nanofibres. The degradation products of the CPC scaffolds did not exhibit cytotoxicity and promoted wound closure by fibroblasts in vitro. In addition, CPC scaffolds showed increased growth of smooth muscle cells, an essential component for functional regeneration of urethral tissue. Furthermore, in a chicken embryo-based assay, CPC scaffolds demonstrated significantly higher angiogenic potential, indicating their ability to promote vascularisation, a crucial aspect for successful urethral reconstruction. Overall, these results suggest that CPC hybrid scaffolds containing both natural and synthetic components offer significant advantages over conventional acellular or synthetic materials alone. CPC scaffolds show promise as potential candidates for further research into the reconstruction of the urethra in vivo.

Abstract
The quest for an ideal wound dressing material has been a strong motivation for researchers to explore novel biomaterials for this purpose. Such explorations have led to the extensive use of silk fibroin (SF) as a suitable polymer for several applications over the years. Unfortunately, another major silk protein—sericin has not received its due attention yet in spite of having favorable biological properties. In this study, we report an approach of blending SF and silk sericin (SS) without the usage of chemical crosslinkers is made possible by the usage of formic acid which evaporates to induce β-sheets formation to form cytocompatible films. Raman spectroscopy confirms the presence of SF/SS components in blend and formation of β-sheet in films. In situ, gelation kinetics studies were conducted to understand the change in gelation properties with addition of sericin into SF. Methyl thiazolyl tetrazolium and live/dead assays were performed to study cellular attachment, viability and proliferation on SF/SS films. The antibacterial properties of SF/SS films were tested using Gram-negative and Gram-positive bacteria. The re-structured SF/SS films were stable, transparent, show good mechanical properties, antibacterial activity and cytocompatibility, therefore can serve as suitable biomaterial candidates for skin regeneration applications.
