Filter elements can be made of various materials: metal meshes, wire, plates, cardboard, paper, non-woven material, felt, fibreglass, wood, and others.
Therefore, here, mainly, solid products made of metal sheet materials are used.
Another method for producing holes and grooves is the ultrasonic method, which is effective for processing brittle materials (glass, ceramics, etc.).
The tool is fed through conductor bushings made of diamond, sapphire and other hard materials.

Introduction Seaweeds waste, generated from seaweed materials after being employed for production of sodium alginate, iodine, mannitol and fucoidan, is a main oceanic material in related industries [1].
Currently more than 70% of agricultural, oceanic and forest materials are nonproductive and are wasted in processing.
Materials and methods Incubation on solid seaweeds waste media Cantharellus sp. was preserved in the Applied and Marine Microbiology Lab at Harbin Institute of Technology at Weihai, China and initially incubated on potato dextrose agar (PDA) dishes.

Thermal control design of the combination of star sensor Using C-C graphite materials For the thermal control of the combination of star sensor, the low temperature thermal control requirements can generally be meeted by the heater compensation.
The design scheme based on the better thermal conductivity C-C graphite materials was proposed.
In the design scheme, shapes of C-C graphite materials can be customized according to the different bracket structure of star sensor.

For TRIP steel, the microstructure changed greatly during deformation and microstructure development influence the macro behavior of the materials, micro materials behavior should be investigated carefully during the deformation [9-11].
As metallic materials, TRIP steel was dissipative materials, so internal variables were used to describe the plastic behavior.
