today's disk
Today, the Shanghai and Shenzhen stock indexes showed a shock pattern as a whole. The three major indexes opened higher at the same time. Among them, the Shanghai index remained high and fluctuated, while the gem index fell significantly. On the whole, the pattern of strong Shanghai and deep weak Shanghai is obvious.
From the industry sector growth ranking, cloud games, virtual digital people, games, mobile game concept, cultural media, e-sports, optoelectronics, online games, meta universe concept and other sectors led the increase, while rubber products, low-carbon metallurgy, wind power equipment, logistics industry, propylene oxide, shipping port, heparin concept and other sectors led the decline. As of the issuance, the number of gainers has exceeded 2900 and the number of losers has exceeded 1400, with obvious profit-making effect. The net purchase of northbound funds exceeded 3 billion.
message interpretation
According to a study published in ACS Nano, a journal of the American Chemical Society (ACS), the German electron synchrotron (desy) team has developed an innovative method to turn nanoparticles into simple hydrogen storage. The team led by Andres Steele, head of desy nano laboratory, designed a new method to store hydrogen in tiny nanoparticles with a diameter of only 1.2 nm made of precious metal palladium. Researchers say palladium can absorb hydrogen like a sponge.
As a highly volatile gas, hydrogen is considered to be a promising future energy carrier and can be used as an environmentally friendly fuel in aircraft, ships and trucks. However, hydrogen storage costs are high and the gas needs to be stored in pressurized containers up to 700 bar or cooled to minus 253 ° C for liquefaction. Both processes require additional energy consumption. The organization pointed out that the hydrogen energy industry chain is divided into three links: hydrogen energy production, hydrogen energy storage and transportation and hydrogen energy application, among which the storage and transportation link is the key to the efficient utilization of hydrogen energy. In terms of cost, the cost of hydrogen storage and transportation accounts for about 30% of the total cost. Economy and efficiency is the future development trend of hydrogen energy storage and transportation.
Therefore, under the background of carbon neutralization and carbon peak, hydrogen energy, as one of clean energy, will further expand its future application with the continuous upgrading of technology. Therefore, this direction deserves long-term attention.
should focus on strategies and directions
Today is the last trading day before the festival. In the morning, the gem was blocked near 3350 points, and the rise and fall were obvious. It is expected that the overall market will still maintain the shock trend in the afternoon, with little probability of sharp rise and fall. The market after the festival should be further analyzed according to the news during New Year's day. In terms of operation, it is recommended to keep light positions for the festival, focus on the pre added varieties in the annual report, and layout the low underestimated opportunities. 30% of the positions can be used, and the positions can be adjusted according to the situation after the festival.
