Most research proves that weld corrosion originates from the material factors introduced during the welding process. However, it is noted that local fluid turbulence due to the weld reinforcement height (WRH) plays an important role in the non-uniform corrosion of welds in flowing media. Accordingly, the individual effect of the local flow on the weld corrosion of low alloy steel was analyzed by experiments and simulation in this study. Electrochemical measurements and morphology observation were conducted, combined with flow field analyses. The results showed that local fluid turbulence due to WRH affected the non-uniform corrosion of low alloy steel welds. The upstream surface and the backflow surface had the highest and lowest corrosion rates, respectively. Interestingly, the high flow velocity surface region did not have a high-corrosion rate. This is due to the combined effects of mass tran...

Chelating agents can enhance the extraction effect of heavy metals from soil by plants. In this study, low molecular weight organic acids (LMWOAs), such as citric acid (CA), tartaric acid (TA) and polyaspartate (PASP), were added to the farmland soil contaminated with Cd and Pb and combined with corn to enhance the absorption and extraction of Cadmium (Cd) and Plumbum (Pb). The effects of LMWOAs on the growth and yield of maize, Cd and Pb concentrations in each part of maize, rhizosphere soil pH, total cadmium and lead content and DTPA-Cd and Pb concentrations were studied. The enrichment, transport and extraction ability of maize were analyzed, and calcium chloride (CaCl2) was compared. The results showed that: (1) Exogenous LMWOAs increased the biomass and yield of maize compared with no material added (CK), and CA increased the yield of maize by 6.33%. (2) Exogenous LMWOAs promoted the uptake of C...

Two 13% Cr–4% Ni stainless steel samples were obtained by different melting and heating processes. One was of relatively low toughness but high ductility (LTHD), and the other was of relatively high toughness but low ductility (HTLD). This paper is to clarify the relationship between the mechanical properties and the CE resistance of the experimental steel samples. The CE of the two materials was studied using an ultrasonic vibration cavitation erosion rig. Mass loss, morphological observation, nanoindentation characterization, and tensile tests were employed to clarify the erosion mechanism. The results showed that LTHD stainless steel had slightly higher ductility, but lower toughness than HTLD material. The mass loss method verified that the CE resistance of LTHD material was higher than that for the HTLD material. In addition, both materials had ...

Experiments were conducted in May 2020, on Cd-contaminated land in Tong Ling, An Hui, China. The efficacy of optimized fertilization and heavy metal passivators—gypsum, bamboo charcoal, lime, and a compound passivator (mixture of bamboo charcoal, silicon fertilizer, gypsum, furfural residue, plant ash, and chicken manure)—was evaluated as amendments to reduce the uptake of Cd in rice. The results indicate that all treatments reduced the Cd bioavailability in Cd-contaminated soil and rice grain Cd accumulation to levels that meet national food safety standards. Moreover, the rice yield increased by 4.80 to 14.27% and the Cd content in rice grains decreased by 23.53 to 36.83%. The efficacy of Cd reduction in rice was as follows: optimized fertilization > lime > compound passivator > bamboo charcoal > gypsum powder. Wheat wa...

However, there are few studies on how plants and soils respond to the chelating agents. In this study, the responses of French marigold(Tagetes patula L.) and soil cadmium (Cd) to the chelator tetrasodium glutamate (GLDA) was investigated in a 180 d field trial. Five GLDA treatments (0,292.5, 585, 1170, and 2340 kg hm− 2) were carried out in a Cd-contaminated soil (0.47 mg kg− 1) under French marigold plantation. The results showed that the application of GLDA significantly increased the exchangeable Cd and cell wall Cd accumulations by 42.13% and 9.39% (p < 0.05), respectively. Furthermore, increases occurred in soil pH, as well as DOC and DTPA-Cd contents with increasing the total amount of GLDA. The composite application of GLDA (2340 kg hm− 2) with French marigold reduced the total soil Cd content by 7.59% compared with the...

However, therapeutic strategies to modulate the immunosuppressive microenvironment of lymph nodes have been largely overlooked. Here, we designed an albumin nanoparticle, Nano-PI, containing the immunomodulators PI3Kγ inhibitor (IPI-549) and paclitaxel (PTX). We treated two breast cancer mouse models with Nano-PI in combination with α-PD1, which remodeled the tumor microenvironment in both lymph nodes and tumors. This combination achieved long-term tumor remission in mouse models and eliminated lung metastases. PTX combined with IPI-549 enabled the formation of a stable nanoparticle and enhanced the repolarization of M2 to M1 macrophages. Nano-PI not only enhanced the delivery of both immunomodulators to lymph nodes and tumors but also improved the...

The initial network is set to structural balance and connection, which implies that the network could be divided into two subnetworks, with cooperation internally while competition externally. A combination of the novel classification strategy and the distributed control protocol based on potential functions is given to solve this problem. Under this strategy and standard assumptions, the multiple uncertain Euler-Lagrange agents can maintain structural balance in cooperation-competition network and the bipartite static consensus can be reached in the evolution. Finally, the accuracy of the derived analytical results can be verified by a simulation example.

Two types of electrochemical tests, namely the ex situ electrochemical impedance spectroscopy test and the in situ potentiostatic polarization test, were conducted to evaluate the erosion–corrosion resistance of as-sprayed and as-sealed AMCs. The results show that the aluminum phosphate–sealed AMC exhibits the best erosion–corrosion resistance with the higher critical flow velocity compared with the as-sprayed AMC, which is attributed to the deep penetration of aluminum phosphate and high hardness of the sealed layer. In contrast, the sealants of stearic acid and cerium salt are easily removed by sand particle impacting, deteriorating their erosion–corrosion resistance.

The study focusing on the effect of impact angles on CFV behavior contributes to the further understanding of the CFV mechanism for erosion–corrosion. In this paper, the CFV behavior for erosion–corrosion of 304 stainless steel at different impact angles was investigated in the simulated sand-containing sea water. The testing methods involve the potentiostatic polarization test, mass loss measurement, surface roughness measurement, and morphology analysis. The results show that the CFV values are 15 m/s for 30°, 13 m/s for 45°, 13 m/s for 60°, and 13 m/s for 90° impact angels, respectively. The variation of CFV values with impact angles depends on the synergistic action between the normal momentum and the shear momentum, which influences the depassivation–repassivation behavior of passive films formed on the metal surface. With the increase of the impact angle, the dominant erosion–corrosion mechanism converts from the micro-cutting to the plastic deformation mechanism.

This work aimed to study the relationship between the adsorption behavior of Cd(II) by MCFN and contact time, initial concentration, MCFN dosage, pH, oscillation rate, and temperature through a batch adsorption method. The adsorption kinetic and isotherm behaviors were well described by the pseudo-second-order and Langmuir models. The batch characterization technique revealed that MCFN had several oxygen-containing functional groups. Using Langmuir model the maximum adsorption capacity of MCFN for Cd(II) was 97.09 (mg/g) at pH 6, 25, dosage of 0.2 g, and contact time of 180. Thermodynamic study indicated that the present adsorption process was feasible, spontaneous and endothermic at the temperature ranging 25 - 55℃. The results of this study provide an important enlightenment for Cd removal or preconcentration of porous ceramic nanomaterials adsorbents for environmental applications

Biological soil crusts (BSC), which are ubiquitous in paddy fields, have been shown a high ability to capture trace metal elements. In the present study, we investigated the effectiveness and mechanism of BSC for immobilizing As, and tested their potential to alleviate the stress of As on rice germination. It is found that BSC can remove 77.8% of arsenic in solution with 3.5 mg L-1 initial As concentration. The As content in BSC reached 514.5 mg kg-1 after 216 h exposure, and the entrapped As was mainly distributed in BSC as a non-EDTA-exchangeable fraction, which might be intracellularly accumulated. Proteobacteria and Bacteroidetes were the dominant phyla in BSC after being exposed to As, playing a significant role in tolerating As and As biogeochemical cycling. The presence of BSC notably promoted the germination rate (18.3%) and dry biomass (103.4%) of rice seeds under 3.5 mg L-1 As stress while reducing the As content in plant roots (8.2-34.3%) and shoots (8.7-47.6%). These findings demonstrate that BSC have a great entrapping effect on As and highlight the importance of BSC in alleviating the stress on rice germination by As, providing a potential nature-based and low-cost strategy to decontaminate paddy fields polluted with As.
