The Al-Si alloy prepared by the traditional powder metallurgy method has the problems of difficult sintering and low mechanical properties. In this paper, rotary extrusion combined with rapid solidification/powder metallurgy technology (RS/PM) is proposed and designed to produce an Al-10Si alloy. In subsequent sintering at different temperatures, better metallurgical bonding between particles can be achieved to fulfil the aim of improving the mechanical properties of the material. Additionally, the continuous preparation of materials can be achieved. Finally, it is verified that the density of the Al-10Si alloy sintered at 525 °C is 2.61 g/cm³, reaching 97.0% of the theoretical density, and the tensile strength reaches 336 MPa, which is much higher than that of the alloy prepared by the traditional casting method and powder metallurgy method.

ZnWO₄@NiCo2O₄ core-shell nanosheet array composites are synthesized on nickel foam via a two-step hydrothermal method. The samples show a specific capacitance of 875 C g⁻¹ at 1 A g⁻¹, and also maintain 81.1% capacitance after 10 000 cycles.

A new type of highly sensitive electrochemical sensor for the detection of dopamine (DA) and uric acid (UA) was constructed by using organic framework (COF) and multi-walled carbon nanotubes (MWCNTs) as the core building units.

Dopamine (DA) and uric acid (UA) play pivotal roles in the human central nervous system, necessitating the urgent development of a rapid, specific, and highly sensitive detection method for the early diagnosis and treatment of related diseases.
