Oversupply of polyethylene is difficult to get rid of
Recently, Rob Stier, senior director of petrochemicals at S&P Global Platts Analytics, said: “As capacity returns to the market, supply will increase, and demand is unlikely in the short term. There is a strong recovery, so polyethylene prices in the global market will be under pressure in 2021.”

Researchers find better ways to design metal alloys
From automobiles to artificial satellites, from building materials to electronic products, high-grade metal alloys are essential in key parts of modern life. However, due to researchers' vague understanding of the boundaries between the tiny crystal grains that make up most metals, the development of new alloys with the best strength, hardness, corrosion resistance, conductivity and other properties for specific purposes is limited.
