class of materials with superior mechanical properties and corrosion resistance [10,23]. 2 Theories and The aim of this work is to develop machine learning to quantify three metrics dictating pitting corrosion resistance of high-entropy alloys. The inputs of the machine learning models are
Sep 1, 2022 · A large-scale study involving data from 28 composting systems fed from commercial pig farms showed that reactor composting had the best results in terms of material degradation, nitrogen loss, antibiotics, and antibiotic resistance genes compared to conventional such static heap and windrow systems (Awasthi et al., 2019c, Awasthi et al
that some digestates rich in heavy metals, microplastics (MPs), and antibiotic resistance genes (ARGs) cannot be directly used for agriculture or forestry and should be further disposed of by other [47–49]. In addition, high cost, process complexity, and a significant loss of plant nutrients also need to be addressed.
Improving the electrical resistance at the material electrolyte interface. Posing as a physical barrier against O 2 ,H 2 O and corrosion ions, such as Cl - and SO 4 -2 . Kinetic, thermodynamics and nature are the key factors affecting the environment, and to understand corrosion resistance, it is imperative to have comprehensive scientific
Feb 23, 2024 · Magnesium alloys, notably AZ31B, hold promise for lightweight structural applications in the aerospace, automotive, and biomedical sectors due to their excellent strength-to-weight ratios. The broad adoption of these alloys, however, is hindered by their inherent susceptibility to corrosion, reducing durability and functional integrity in corrosive environments. This study explores anodic
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
Jul 1, 2023 · Plasma electrolytic oxidation (PEO), as a cost effective and environmentally friendly technology, has been applied on magnesium and its alloys to improve wear and corrosion resistance. Additionally, combining with particles addition in the electrolyte and/or various post-treatments could diminish the intrinsic structural defects of the PEO coatings and provide multifunctionalities, including
Jun 15, 2022 · 1. Introduction. Globally, more than half of all antibiotics produced are used in animal husbandry (Van Boeckel et al., 2017; Wang et al., 2019).The larger amount of antibiotics utilization produced selective pressure for microbe in livestock fermentation systems to obtain and remain antibiotic resistance genes (ARGs), and the resistant ability was fostered gradually by the enrichment of the
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].
Nov 1, 2023 · To further investigate the corrosion resistance, the open circuit potential (OCP) curve, potentiodynamic polarization curve (Tafel curve), and electrochemical impedance spectra were measured [41]. After stabilization for 4000 s, the OCP value of the bare sample was the most negative (−1.55 V) ( Fig. 6 a ), indicating the excellent corrosion
Mar 7, 2021 · Organic solid waste is considered a renewable resource that can be converted by various technologies into valuable products. Conventional thermophilic composting (TC), a well-studied and mature technology, can be applied to organic solid waste treatment to achieve waste reduction, mineralization, and humification simultaneously. However, poor efficiency, a long processing period, as well as
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
