Due to its high practicability, metal assisted chemical etching (MACE) has become a popular silicon micro-nano structure preparation method. This paper explores the nanoparticle film dissolution and re-deposition evolution behavior in oxidizing HF solution during MACE process. The results show Ag nanoparticles experience both oxidation dissolve reduction deposit HF–H2O2–H2O HF–Fe(NO3)3–H2O corrosion solution. Au can remain stable solution, providing strategy keep patterns' accuracy of...
Oriented silicon steel is vital for power transformer cores, while the high-temperature annealing process limits industrialization of environmentally friendly coatings on surface. In this paper, binders Al(H2PO4)3 solution and silica sol were introduced innovatively. They condensed into macromolecular polymer chains, network structures SiO2 particles at high temperatures, providing stability adhesion.

Semiconductor heterojunctions can significantly enhance photocatalytic degradation efficiency by facilitating rapid interfacial charge transfer.
Metal-assisted catalyzed etching (MACE) technology is convenient and efficient for fabricating large-area silicon nanowires at room temperature. However, the mechanism requires further exploration, particularly dynamic effect of various ions in acid-etching solution. This paper investigated MACE wafers predeposited with metal nanofilms an HF-M(NO3)x-H2O solution (where M(NO3)x nitrate fourth-period elements periodic table). The oxidizing ability Fe3+ NO3− was demonstrated, influence on...

Coal tar pitch is the residual black substance after distillation of tar, which has low value; It mainly contains anthracene, phenanthrene, pyrene and other components that are difficult to volatilize. stable performance rich carbon content. The proportion more than 90% in coal pitch. theoretically feasible use as source prepare graphene. At same time, preparation expensive graphene from low-cost great advantages economic benefits.
Abstract During the long-term use of coating, environmental factors, physical damage or other factors may cause micro-cracks in coating. The expansion microcracks will destroy overall structure reduce protective effect coating and degrade its mechanical properties. However, traditional repair methods need to consume a lot manpower material resources, are difficult be repaired by external means. Inspired biological systems, intelligent coatings with certain self-healing ability have attracted...
Abstract In the fields of military industry, national defence and major engineering, oriented silicon steel is an indispensable material, but chromium-containing insulating coating coated on its surface harmful to environment humans.
