The sky is high and the autumn breeze is cool. 21-24 August 2022, the first national magnesium resources utilization academic conference was held in the world magnesium capital – Anshan City, Liaoning Province. This conference is themed on promoting high-quality development, taking reform and innovation as the fundamental driving force, taking green safety as the […]

Nanomaterials with diameters of <100 nm are being used in a number of applications across multiple domains such as biology, physics, chemistry, cosmetics, optical components, polymer science, pharmaceutical drug manufacture, toxicology, and mechanical engineering. This article discusses the properties and applications of magnesium oxide nanoparticles. Magnesium is a Block S, Period 3 element, while oxygen

This thesis uses the new type of nano hydroxide powder as the research object. Firstly, the main factors affecting the scattered nanowl powder in the rubber matrix are examined.The decentralized state in the matrix (butyra rubber, ternary ethylene rubber, butadylene rubber, silicon rubber). The results show that the viscosity of polymer matrix and the surface

EPDM has excellent heat resistance, aging resistance, corrosion resistance and insulation performance, and is widely used in wire and cable, automobile, home appliances and other fields, but EPDM is extremely flammable, and is restricted in some applications. In this paper, the feasibility of the application of 9,10-dihydro-9-oxa-10-phospha-phenanthrene oxide (DOPO) in EPDM rubber is discussed. DOPO

As an important chemical product, magnesium hydroxide nanomaterials have been widely used in ceramics, flame retardant, catalytic, pharmaceutical and environmental protection fields. The morphology, size and dispersion of MgOH micro- and nanomaterials affect their application properties, so they need to be controlled. In this paper, the morphology, size and dispersion of magnesium hydroxide products were

Leaching is often equated with wet metallurgy in the mining industry. However, leaching is only one of the operations included in hydrometallurgy. Moreover, the process of hydrometallurgy can be carried out without leaching, for example, the precipitation of magnesium oxide from seawater using burned dolomite, a major source of magnesium. Other major hydrometallurgical operations include

Magnesium oxide nanoparticles have long-lasting and broad-spectrum antibacterial activity, and are UV-independent, safe, non-toxic, stable and have great potential for application. Different metal ion-doped magnesium oxide nanoparticles were prepared by coordination-precipitation, homogeneous precipitation and sol-gel methods, and their morphology and antibacterial activity were investigated. The results showed that magnesium oxide nanoparticles doped with different metal

Magnesium oxide nano powders with different particle sizes (10~100 nm) and crystallinity were synthesized by the citric acid sol-gel method using magnesium nitrate hexahydrate as the precursor. The effect of citric acid on the stability of the sol-gel and the effect of roasting temperature on the particle size and crystallinity of the powders were investigated.

The flame retardant effect of metal hydroxide is mainly the release of water by heat absorption and decomposition, when it is added to the polymer with high filling amount, the flame retardant polymer is brought by metal hydroxide when it is decomposed by heat – a series of physical effects: the release of water and

Highlights •Antimicrobial nanoparticles (NPs) are widely used in dental materials to improve their biological properties. •Magnesium Oxide (MgO) NPs are novel antimicrobial agents. •Incorporation of MgO NPs in dental cements aids in minimizing bacterial colonization at the restoration margin. •Zein polymer facilitates the dispersion of MgO NPs and avoid its agglomeration. •Zein polymer effectively enhances the
