Catalytic partial oxidation of methane to syngas over perovskite catalysts

Partial oxidation of methane (POM) significantly offers benefits to the industrial production of syngas in comparison with other conventional processes in terms of hydrogen (H2)/carbon monoxide (CO) ratio and degree of catalyst deactivation induced by carbonaceous species. Thus, the increasing concern on commercialisation of POM technology has driven the catalyst system to enter another stage of developing a novel catalyst, namely perovskite. POM is comprehensively reviewed and compared with various perovskite catalysts. Apart from studying process chemistry to understand POM reaction, the role of metal types for perovskite structure on catalytic performance and coke selectivity are also scrutinised and summarised. Additionally, the comprehension of POM pathways and the corresponding pictorial depiction are discussed and provided in this paper

The State of the Art of Natural Polymer Functionalized Fe₃O₄ Magnetic Nanoparticle Composites for Drug Delivery Applications: A Review

Natural polymers have received a great deal of interest for their potential use in the encapsulation and transportation of pharmaceuticals and other bioactive compounds for disease treatment. In this perspective, the drug delivery systems (DDS) constructed by representative natural polymers from animals (gelatin and hyaluronic acid), plants (pectin and starch), and microbes (Xanthan gum and Dextran) are provided. In order to enhance the efficiency of polymers in DDS by delivering the medicine to the right location, reducing the medication’s adverse effects on neighboring organs or tissues, and controlling the medication’s release to stop the cycle of over- and under-dosing, the incorporation of Fe3O4 magnetic nanoparticles with the polymers has engaged the most consideration due to their rare characteristics, such as easy separation, superparamagnetism, and high surface area. This review is designed to report the recent progress of natural polymeric Fe3O4 magnetic nanoparticles in drug delivery applications, based on different polymers’ origins
