The World Bank expects global economic growth to slow significantly, from 5.5% in 2021 to 4.1% in 2022 and further to 3.2% in 2023. Growth in East Asia and the Pacific is expected to slow to 5.1 percent in 2022, reflecting the impact of China's economic slowdown, the report said. China's economic growth is expected to fall to 5.1% in 2022, close to potential growth, due to the ongoing impact of the COVID-19 pandemic and the Chinese government's tightening of regulations in certain sectors of the economy. The report said that the rapid spread of the Omicron variant means that the new crown epidemic is likely to continue to disrupt economic activity in the near future. In addition, decelerating growth in major economies, including the United States and China, will depress external demand in emerging markets and developing economies.
Slow economic growth has a huge impact on nanodiamond powder.
Introduction to Nanodiamond Powder
Diamond is a mineral composed of carbon and is an allotrope of carbon. Diamond is the hardest substance found naturally in nature.
Nanodiamonds or diamond nanoparticles are diamonds with a size less than 1 micron. Due to their cheapness, large-scale synthesis, surface functionalization potential, and high biocompatibility, nanodiamonds have been widely studied as potential materials for biological and electronic applications as well as quantum engineering.

Applications of Nanodiamond Powder
For ultra-fine polishing:
Polishing is the traditional field of diamond application. Even today, polishing, including ultra-fine grinding, is still one of the most important processes in instrument and mechanical manufacturing processes. At present, the commonly used abrasive size is greater than 0.1 μm (100nm), nanodiamonds have high hardness, the particle size is one order of magnitude smaller than the best abrasive, and the carbon surface is easily affected by the chemical change, and can be compatible with any polar medium, this feature makes it possible to uniform distribution of nanodiamond particles in the carrier. Therefore, nano-diamond particles are regarded as a new generation of ideal abrasives for ultra-fine polishing.
Due to its high hardness, diamond freely grinds the tip of the friction surface and quickly removes the uneven micro-peaks on the surface of the friction pair. It is an extremely precise grinding and polishing process, which cannot be achieved by ordinary mechanical processing. This effect makes the contact area between friction pairs increase rapidly, accelerates the running-in process, and improves the running-in accuracy. The spherical and quasi-spherical particles of nano-diamond are embedded in the contact concave between the friction pair. With excellent bearing capacity, the friction surface forms a ball bearing effect, showing good lubricity, turning sliding friction into rolling friction, reducing friction resistance, and avoiding the dry wear phenomenon.
For nanodiamond composite plating:
Nanodiamond has the properties of super hard, high wear resistance, heat resistance, and corrosion resistance of diamond, and its particle surface is rich in hydroxyl, carboxyl, carbonyl, and other functional groups, so it has a strong bonding force with the coated surface. Even with a small amount, it can significantly improve the performance, so it is very suitable for composite plating. It can not only be used for metal surfaces, but also for rubber, plastic, glass, and other surface coatings.
For magnetic recording systems:
Adding nanodiamonds to the ferromagnetic layers of tape and disk can significantly reduce magnetic domains (particles of ferromagnets) and significantly increase the density of the recording.
And introducing nanodiamonds into the clean special film of the magnetic head can significantly increase its wear resistance.
For medical use:
Nanodiamond has high adsorption capacity, large specific surface area, a large number of free electrons on the surface, its nano-size, a large number of oxygen-containing functional groups on the crystal surface, chemical inertia of particles, and hydrophilic surface characteristics, making it can be used for therapeutic agents.
It can be applied to oncology, gastroenterology, cardiology, the diagnosis and treatment of vascular disease, etc., they are not carcinogenic or mutagenesis, without poison.
Nanodiamond has very high activity against viruses, microorganisms, and bacteria. Due to their high adsorption capacity and other unique characteristics, they will be strongly absorbed and they are super active adsorbents. In addition, nanodiamond is also useful for gastrointestinal diseases, and it is the best means to prevent burns, various skin diseases, and visceral poisoning after effects.
Nanodiamond is used in aqueous and oily suspensions, which is beneficial to the enhancement of tumor medicinal reagents, the normalization of intestinal peristalsis, the improvement of blood indicators, and the improvement of the activity of life and immune system, the discharge of viruses from the body and so on.
