A novel DC-assisted fast hot-pressing (FHP) powder sintering technique was utilized to prepare Al/Diamond composites. Three series of orthogonal experiments were designed and conducted to explore the effects of sintering temperature, sintering pressure, and holding time on the thermal conductivity (TC) and sintering mechanism of an Al-50Diamond composite. Improper sintering temperatures dramatically degraded the TC, as relatively low temperatures (≤520 °C) led to the retention of a large number of pores, while higher temperatures (≥600 °C) caused unavoidable debonding cracks.

- Global health governance is a complex, evolving system that faces challenges from local and regional health policies in different countries.
- The COVID-19 pandemic prompted global health agencies to initially promote strict control measures, but later shifted to a stance encouraging countries to adapt to living with the pandemic.
- The research examines the health policies of Russia, Pakistan, and China, highlighting that effective measures are necessary at all levels for countries to successfully manage ongoing pandemic challenges.
As one of the widely studied metal nanoclusters, the preparation of copper nanoclusters (Cu NCs) by a facile method with high fluorescence performance has been the interest of researchers. In this paper, a simple, green, clean, and time-saving chemical etching method was used to synthesize water-soluble Cu NCs using ascorbic acid (AA) as the reducing agent. The as-prepared Cu NCs showed strong green fluorescence (with a quantum yield as high as 33.
