Nanoporous materials are well known to be technologically useful for a wide spectrum of applications such as energy storage and conversion in fuel cells, solar cells, Li-ion batteries, hydrogen storage and supercapacitors, catalysis, sorption applications, gas purification, separation technologies, drug delivery, cell biology, environmental remediation, water desalination, purification, separation, sensors, optical, and electronic and magnetic devices. Typical examples of natural and synthetic nanoporous solids are zeolites, activated carbon, metal-organic frameworks, covalent organic frameworks, ceramics, silicates, nonsiliceous materials, aerogels, pillared materials, various polymers, and inorganic porous hybrid materials. However, the applicability of the porous nanomaterials depends on their targeted design at the atomic and molecular level which controls their porosity and surface area. The nanoporous materials can be synthesized in the laboratories using organic or inorganic templates. The self-assembly of organic templates or the existing pore size of the inorganic templates controls the porosity of the final product. In addition, the nanometer-size pores can be utilized to impregnate nanoparticles/proteins/ions to create multifunctional hybrids of practical and scientific interests. Considering the widespread applications of these nanoporous materials, uncovering their recent synthesis approaches, structure-dependent properties and potential applications in various disciplines of science and engineering are necessary and urgent.

The company needs to process eight M12 wire holes when processing Q034 series bond plates. In the past, drilling with a jig on a drill press had to be preceded by scribes and then holes were drilled one by one, and then the holes were expanded one by one. Not only were the tolerances difficult to guarantee, but also each work piece had to be clamped twice, which resulted in low work efficiency and labor intensity. For this reason, the company has made innovations to improve the drilling of the perforated sheet hole drill to the same time as the drill hole, which breaks the limitation that only one hole can be drilled at one time in the ordinary drilling machine. It can not only drill 8 holes at the same time, but also replace the mandrel sleeve according to the processing requirements. It can guarantee the requirement of 8-hole center distance, but also can increase the processing range of the workpiece. It can process 7 kinds of Q034 series combination discs with different inner holes, which greatly reduces the processing cost of the workpiece and can save the processing cost by more than 20,000 yuan.
Double Star Machinery developed a multi-head drilling machine
After more than two months of improvement, a multi-head drilling machine with simultaneous drilling of holes was born at Qingdao Double Star Machinery Corporation.
