Recently, covid 19 outbreak spreads in Shanghai, China. There are more than 25,000 new asymptomatic domestic infections every day. China is implementing a dynamic zero-out policy. A leading respiratory expert said the key to COVID-19 prevention and control is to minimize transmission and fatality rate. Omicron has a low case fatality rate but is highly transmissible and can still claim many lives in large outbreaks. "Total openness is not applicable in China. For China, we should keep to the dynamic zero-out and gradually open up."
However, "dynamic zero clearance" is not the pursuit of complete "zero infection". As the Novel Coronavirus has its own uniqueness and strong concealment, there may be no way to prevent the detection of cases at present, but rapid detection and prompt treatment must be carried out, as soon as one case is found, one case will be dealt with.
The situation in Shanghai is serious. As the financial center of China, Shanghai is a very important city, and the outbreak of the epidemic in Shanghai will put a great impact on China's economy. The current task is to contain the spread of the epidemic as soon as possible, to achieve social zero so that Shanghai's life and economy quickly return to normal.
As China plays an important role in the global supply chain, the outbreak will have a significant impact on the supply and prices of many Cu2O powder.
Si and GaN are major players in semiconductor materials. One material that keeps coming up in research is cuprous oxide. Cuprous oxide is one of the first materials discovered to have semiconducting properties.
What is Cuprous Oxide?
Cuprous oxide is a semiconductor with a band gap ranging from 2.0 to 2.2eV and has photovoltaic characteristics. As a p-type oxide of copper with chemical formula Cu2O, it can exist in the form of thin films or nanoparticles and is very useful for basic research due to its low cost and new physical properties.
Over the past few decades, researchers have identified a variety of ways to synthesize cuprous oxide. Some of the techniques found were:
Chemical vapor deposition
Sol-gel dip coating technology
Even after extensive research, a significant barrier to the use of these methods is the generation of mixed phases of Cu, CuO and Cu2O, resulting in few applications for cuprous oxide as a semiconductor.
Cuprous Oxide Electronic Properties
Research on cuprous oxide has been ongoing to understand its electronic properties and potential as a semiconductor material.
A research team reports that when it is doped with 12.5% zinc, its optical properties are improved and can be used in photocatalytic and sensor devices. According to another group, the band gap was reduced from 1.96eV to 1.91eV when it was mixed with F element at a concentration of 0.34%.
However, its photovoltage and photocurrent density are increased to 0.4457V and 2.79mA/cm2, respectively.
Cuprous Oxide Application
Major applications of cuprous oxide in electronics include supercapacitors, lithium ion batteries, photocatalysis, solar energy conversion and sensing applications.
Electrodes for supercapacitors and lithium-ion batteries:
Cuprous oxide is suitable as an anode material for lithium-ion batteries because of its controllable structure, polymorphic form, and high cycling capacity.
Photocatalysis and solar energy conversion:
Due to the abundance of copper and oxygen in nature, appropriate visible light absorption band gaps, and relatively easy and inexpensive manufacturing, cuprous oxide is suitable for large-scale solar conversion.

Russia's Rokot-M carrier rocket is scheduled to launch for the first time in 2024.
The first launch of the Rokot-M carrier rocket is planned for 2024 from the Plesetsk cosmodrome, the general manager of the Khrunichev National Space Research and Production Center told TASS. The Rokot-M, a lightweight carrier rocket powered by liquid fuel, began development in 2018, with The Russian side using domestic components instead of Ukrainian components.
