The development of catalysts with suitable adsorption behavior for the reaction molecules and the elucidation of their internal structure-adsorption-catalytic activity relationships are crucial for the electrooxidation of 5-hydroxymethylfurfural (HMF). In this work, NiO-CuO heterostructures with a spontaneous built-in electric field (BEF) are specifically designed and used to regulate the OH adsorption site for freeing up the active site of HMF for the HMF oxidation reaction (HMFOR). The mechanism driving electron pumping/accumulation of the BEF is examined by X-ray photoelectron spectroscopy (XPS) and ultraviolet photoelectron spectroscopy (UPS).

Currently, the sol-gel technique is employed in the synthesis of high-performance vitrified bonds; however, its application in the fabrication of stacked abrasives has been minimally explored. Furthermore, the methods utilized in the production of abrasive particles for stacked abrasives are technically challenging and incur high costs, which hinders their actual industrial application. Consequently, this study utilizes the sol-gel approach to synthesize a NaO-BO-SiO ternary system vitrified bond powder and employs a molding and crushing method, which offers a lower technological barrier and reduced preparation costs, for the production of abrasive particles subsequently fabricating corundum stacked abrasives.

This study utilized bismaleimide (BMI) resin, reinforced with introduced ether bonds, as a binding matrix, in combination with silicon carbide (SiC), for the fabrication of composite materials. A thorough investigation was conducted to assess the influence of diverse processing parameters on the mechanical properties and high-temperature thermo-oxidative stability of these composites. Experimental results indicate a notable improvement in the mechanical properties of the composites upon the incorporation of ether bonds, in contrast to their unmodified counterparts.

Intravenous (IV) iron supplementation is the preferred treatment option for managing severe iron deficiency (ID) and ID anemia (IDA). Three of the available IV iron preparations are ferric derisomaltose (FDI), ferric carboxymaltose (FCM), and iron sucrose (IS). The objective of the present work was to review the published literature about the efficacy, safety, quality of life (QoL), and economic outcomes of using FDI, FCM, and IS for the treatment of ID.

Titanium alloy, as a recognized difficult-to-cut material, places higher demands on the performance of cutting tools. Compared with the mainstream cemented carbide tools, PcBN tools have a higher life and better machining performance. In this paper, a new type of cubic boron nitride superhard tool was prepared by introducing YO-stabilized ZrO (YSZ) under high temperature and high pressure (1500 °C, 5.

Article Synopsis
  • The tiara[5]arene (T[5]) forms a complex with silver trifluoroacetate, creating a binuclear metallo-pseudorotaxane due to several endo-cavity Ag η-arene interactions.
  • Two of these enantiomeric complexes, denoted as [(CFCOAg)⊂T[5]], are linked by an additional (CFCOAg) dimer through coordination at the exo-wall.
  • This leads to the formation of a distinct handcuff metallo-bis-pseudorotaxane structure when in the solid state.
