Global Copper Market to Reach $298.4 Billion by 2030 What is the resistance of a copper wire?
Copper is an excellent conductor of electricity and has many desirable properties that make it ideal for use in electrical wiring. Some of the reasons why copper is used for most electrical wiring are: 1. High Conductivity: Copper is one of the best conductors of electricity, with a conductivity that is 97% that of silver, the best conductor. This high conductivity ensures that electricity is transmitted with low resistance and minimal energy loss, making it an efficient choice for wiring. 2. Ductility: Copper can easily be drawn into thin wires without breaking. This is important because most electrical wires are thin, and they need to be flexible enough to be used in different types of circuits and installations. 3. Corrosion Resistance: Copper is highly resistant to corrosion and does not corrode easily. This makes it ideal for use in environments where the wire is exposed to moisture, such as in humid climates or under water. 4. Longevity: Copper is a durable material that can withstand wear and tear over time. It does not degrade easily and is not affected by ultraviolet light or exposure to the elements, making it an excellent choice for use in outdoor applications. 5. High Melting Point: Copper has a high melting point, which makes it resistant to heat damage. This is important because electrical wires can generate heat while carrying a current and need to be able to withstand this without melting or becoming damaged. Overall, the combination of its high conductivity, ductility, corrosion resistance, longevity, and high melting point make copper the best choice for most electrical wiring applications

Why does copper make a good metal to use in electrical wiring? Does Copper React With Water?
The conversion of CO2 to useful chemicals and fuels is a major challenge in sustainable energy research. Ethanol, with its high energy density and compatibility with existing infrastructure, is a promising candidate for this conversion. However, the selective conversion of CO2 to ethanol is a challenging process due to the high thermodynamic stability of CO2 and the need for multiple reduction steps. Recently, a team of researchers from the University of Science and Technology of China developed a metal-organic framework (MOF) that contains cooperative copper centres for the selective conversion of CO2 to ethanol. The MOF, named UTSA-74(Cu), is composed of copper nodes coordinated by carboxylate ligands and diazabicyclooctane bridging ligands. The researchers found that the cooperative copper centres in UTSA-74(Cu) exhibited high selectivity (~78%) for the two-electron reduction of CO2 to ethanol, with minimal byproducts. This is due to the unique arrangement of copper centres in the MOF, which allows for the generation of ethylene, a key intermediate in the formation of ethanol, and subsequent reduction to ethanol. Furthermore, the UTSA-74(Cu) MOF showed good stability and recyclability, maintaining its catalytic activity over multiple reaction cycles. The researchers also found that the presence of water in the reaction mixture improved the catalytic activity of the MOF. Overall, the development of MOFs with cooperative copper centres offers a promising approach to the selective conversion of CO2 to ethanol and other useful chemicals. The UTSA-74(Cu) MOF represents a significant step towards sustainable energy production and carbon capture and utilization
