II. How is CBM formed
Coalbed methane (CH4) forms in one of two ways. During the earliest stage of coalification (the process that turns plant detritus into coal), biogenic methane is generated as a by-product of bacterial respiration. Aerobic bacteria (those that use oxygen in respiration) first metabolize any free oxygen left in the plant remains and the surrounding sediments. In fresh water

The materials that have various colors is made and commercialized and the one that is possible for electroplating on it is commercialized too. After the technology for 3D printing is evolved, the price of the materials for 3D printing ink may go down and it causes more and more supply of 3D printer for individual per
