The synthesis of carbon quantum dots can be mainly divided into two categories: top-down method and bottom-up method. Through the pre-treatment, preparation, and subsequent processing, carbon quantum dots can be controlled in size, passivated on the surface, doped with heteroatoms, and nanocomposites to meet the requirements.

Copper is different from metals such as aluminum and nickel in that it is difficult to form a dense and stable intrinsic passivation layer on its surface. Therefore, the exposed copper surface will be continuously oxidized and corroded by oxygen and water vapor in the air. The smaller the particle size and larger the specific surface area of copper powder, the easier it is to rapidly oxidize to produce products such as cuprous oxide (Cu2O) and copper oxide (CuO). This oxide insulation layer significantly reduces the conductivity of copper powder and hinders particle sintering connection, resulting in degradation of the performance of the conductive paste.

Copper and copper alloys have excellent physical and chemical properties, such as high conductivity, thermal conductivity, and corrosion resistance, and are widely used in the power industry, thermal management systems, nuclear power plants, and aerospace industry. High strength, wear-resistant, and corrosion-resistant copper alloys are used for automotive parts and daily necessities.

The 14th Shenzhen International Thermally Conductive Materials and Equipment Exhibition, also known as CIME2025, is set to take place on June 4-6, 2025, at the Shenzhen International Convention and Exhibition Center. With an expansive exhibition area of 20,000 square meters, the event is expected to host 500 exhibitors, 30 academic presentations, and attract approximately 30,000 professional visitors. CIME, originating in Shenzhen in 2013, has evolved over the past decade into a prestigious industry event in the field of thermal management and thermally conductive materials, now hosting exhibitions in Shenzhen in June and in Shanghai in December.
