Nov 20, 2023 · This coating proved to be more resistant to corrosion than the bare one. After meticulous examination, it was noticed that the SS coated with sample B was subjected to slight morphology damage, with pore sizes ranging from 1 to 3 µm. The corrosion media and the brush coating process were the primary cause of this damage.
Mar 25, 2024 · A machine learning framework was proposed and developed to accelerate the discovery of corrosion-resistant high-entropy alloys. We demonstrated that the proposed framework can provide an accurate evaluation of relative corrosion resistance for a wide range of compositions for high-entropy alloys.
Nov 4, 2023 · The results were consistent with our hypothesis that continuous manure application would significantly increase the soil organic carbon (SOC), dissolved organic carbon (DOC), and readily oxidized organic carbon (ROC) content.
Jul 21, 2023 · This study was designed to investigate the efficiency of improved composting equipment in enhancing the composting process of livestock manure. The optimized equipment addresses issues of poor mixing effect, low automation level, and extended composting cycles in traditional composting .
Nov 1, 2022 · Corrosion potential and corrosion current density are the two most important parameters. Fig. 7 shows the polarization curve of pure and composite coating samples immerse in 3.5 wt% NaCl solution for 96 h. The more positive corrosion potential and more negative corrosion current density indicate higher protection efficiency of the coating.
Jan 13, 2024 · Surface modifications are efficient techniques to enhance the corrosion resistance of flaky carbonyl iron (FCI) for electromagnetic wave absorbing coatings. However, with the emergence of diverse harsh service environments (tropical marine climate, etc.), it becomes more challenging for traditional single-layer modification of FCI to meet the durability requirements. Here, a facile synthesis
Dec 1, 2022 · Thus, it is seen that the corrosion resistance improves as shell fraction increases from 22.4% to 31.7%. However, the continuously increased UFG region can restrain the passive film formation rate and increase the number of defects in the passive film. Thus, the corrosion resistance deteriorates gradually with continuously increasing shell
Mar 15, 2021 · One method that combines corrosion inhibitors with “host” system nanocontainers such as polymer-based nanomaterials [18], metal–organic frameworks [19], hollow mesoporous silica nanoparticles [20] and inorganic clay-based nanoreservoirs [21] has demonstrated bright prospect in corrosion protection.
much equipment has been developed to cope with the large quantities involved. Enhanced corrosion in crevices and awkward corners can be avoided at the design stage by the use of round-section tankers and other equipment. Slurry is a mixture of dung and urine, and farmyard manure (FYM) is slurry composted with litter, i.e. straw or wood shavings
Magnesium (Mg) alloys are promising candidates for artificial implants because of their excellent degradability and superior mechanical properties. However, the uncontrolled corrosion hinders their applications. Herein, a composite coating of polycaprolactone (PCL) and copper-based metal–organic framework (MOF) modified with folic acid (FA) was constructed on AZ31 Mg alloy. The modified
Jun 1, 2023 · Four types of manures were selected as raw materials: pig manure, chicken manure, cow manure, and sheep manure. All four types of manures were purchased from farms. Sycamore leaves were used to adjust the C/N of raw materials to about 20. Then the four raw materials were mixed with equal mass, and the initial water content was adjusted to 60%
Mar 15, 2024 · These large amounts of antibiotic residues in livestock manure induce antibiotic resistance in animal gastrointestinal microorganisms [2]. Antibiotics introduced into the environment induce the production of antibiotic-resistant bacteria (ARB) and antibiotic resistance genes (ARGs), which pose a risk to the environment and public health [3], [4].
Sep 1, 2022 · The ARGs reduction was enhanced by 61.0 %, which was mainly related to aminoglycoside resistance genes of antibiotic inactivation and tetracycline resistance genes of antibiotic target protection. These were attributed to the steric hindrance caused by iron corrosion, which inhibited the VGT and HGT.
Jan 1, 2024 · The primary aims of this study were as follows: (1) to examine the resistance profiles and distribution characteristics of microbial communities in cattle manure during various breeding periods and in fertilized soil; (2) to investigate the key factors influencing the variations in bacterial communities and ARGs in cattle manure during
