Founded in 2006, 4Micro is devoted to making breakthrough innovations in natural clean energy under scientific research.

Shanghai 4Micro Technology Co., Ltd. was established in 2006 and is located in the Pharmaceutical Valley of Zhangjiang Hi-Tech Park, Shanghai, China. Before the establishment of the company, the founder spent over fifteen years of scientific research and eventually made huge breakthroughs in the invention and application of new energy and new materials based on mesoscopic quantum technology. The company now mainly engages in the research, development, production and sales of biological and biochemical products, traditional Chinese medicine intermediates, new energy sources and relative derivative products. The idea that "natural energy creates a beautiful world" is the company's constant pursuit. Yezzileaf, which is based on our cutting-edge ‘carbon transfer’ technology, is our signature product.



Yezzileaf is a product using "carbon transfer" technology that produces clean air from carbon dioxide just like nature.

Yezzileaf is a product solution based on the ‘carbon transfer’ technology invented by the founder of 4micro, Eric (Xiaohui) Huang. This ‘carbon transfer’ technology was first introduced in 2015. On November 21, 2016, Eric and his team started a global cooperation initiative on ‘carbon transfer’ at the 50th anniversary ceremony of UNIDO. He is more than willing to provide free samples based on this technology. Aligning closely with the SDGs, this technology will be able to serve as our lost forests in terms of mitigating the greenhouse effect. It has achieved the conversion of carbon dioxide into oxygen without outside power supply, and at the same time it reduces hazardous substances in the air and inhibits bacteria growth. It can contribute to restoring global carbon balance, improving the health of our planet, and bears the potential to counter the negative effects of the world’s industrial development and support the sustainable development of ‘a global community of shared destiny’. We have now established a spatial model with this technology, namely the ‘No Haze, Low Carbon, Carbon Transfer' space. This model, along with the key product to this model solution — Yezzileaf — has already been adopted in many public spaces such as the Beijing South Railway Station, Beijing Capital International Airport and Beijing Lufthansa Centre. Those projects could not only provide high-quality air, but also transfer tens of thousands of carbon dioxide to oxygen annually, an equivalent of 20 hectares of forests in Beijing, which demonstrates a significant influence. In more detail, the product performance test carried out by a National Measurement and Accreditation Laboratory, i.e. the Science and Environment Environmental Analysis Research Center of the Chinese Academy of Sciences, shows that the formaldehyde elimination rate of the 1st and 12th hour in the standard test chamber where the sample of Yezzileaf was placed reached 63.5% and 97.3%, and respectively, the 1st and 6th hour PM2.5 elimination rate reached 81.3% and 96.7%. This means that the product can quickly and dramatically reduce the concentration of formaldehyde and particulates (PM) in the space and still exert its purification effect at low concentrations. Natural oxygen is in the form of three isotopes, namely oxygen 16, oxygen 17, and oxygen 18. Among them, oxygen 16 is the most abundant, accounting for 99.76%, while precious oxygen 17 and oxygen 18 are natural small water molecules, accounting for only 0.04% and 0.2%. Experiments have shown that Yezzileaf contains oxygen 17, oxygen 18 isotopes of water molecules (molecular formula: 17O; 18O), where energy density is much higher than ordinary oxygen molecules. Yezzileaf uses specific small water molecules as the basic raw material, reproduces the natural space field that thoroughly purifies the air, and also greatly reduces energy consumption.
