Recently, Professor Zeng Jie's group at the University of Science and Technology of China has made new progress in the study of plasmonic regulation of localized surface plasmons of low-symmetry metallic nanocrystals. The researchers succeeded in constructing a Pd@AuCu core-
In the central heating project, the laying of heat pipes is one of the most important, especially in the winter due to the sinking of air currents and the general reduction of temperature and haze. The reason why the winter haze phenomenon is more serious is mainly due to the unreasonable heating
1. First consider the use of local exhaust or overall space ventilation or both, the source of pollution is fixed, local exhaust is used, the source of pollution is not fixed, and the whole space is used for ventilation; 2. Local exhausting determines the amount of exhausted

Double filter is also called double switch filter. It is made of two stainless steel filters in parallel. It has a novel and reasonable structure, good sealing, strong flow capacity, and easy operation. In particular, the side leakage rate of the filter bag is small, the accuracy of the filtration
High-purity graphite production process , we may not be particularly familiar with, in life, it is basically not get our special attention, there are not many people to understand. High-purity graphite is a high-purity metal and related semiconductors that use graphite in production. In order to f
Today, the Gude heavy-duty cone crusher manufacturer introduces the common faults and solutions of the cone crusher. Fault 1: The oil pressure in the oil pipe before and after the filter of the cone crusher is different. Cause of malfunction: caused by blockage of the filter
Common troubleshooting techniques for pumps, it is more important to master the troubleshooting techniques of pumps. You must know the working principle of the pump, the structure of the pump, and the necessary operating skills and common knowledge of mechanical maintenance. Wi
Strengthening the management of rice seedlings, preventing the growth of seedlings and improving the quality of seedlings is the key to high yield of rice. However, the current causes of rice seedlings are mainly due to the following reasons: First, the seedlings are ventilated late and the ventil
There are many varieties of waste plastics , and there are many patterns of patterns, which come from different industries. Plastics can be divided into thermoplastics and thermosets according to their structure and properties. At present, China's imported waste plastics are all thermoplastics b
