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
surface, improved solubility, targeted drug delivery and multifunctionality, nanoparticles have emerged as potential drug delivery carriers to tissues throughout the body. Yet passing the BBB is particularly difficult. The proper design of such engineered ‘nanocarriers’ becomes very important in transversing the impermeable membranes to facilitate drug delivery. At the same time, it is also r
(1) Project Objective
To develop a new commercial product that is valuable, feasible, and practical in the real market.
(2) Deciding The Market for The New Product
In this world, there are myriad markets, consumers, products. However, considering our company's technologies(internal factor) and marketability(external factor), we chose the market of kitchen utensils for our new product.
◎압전기 효과
압전기 효과에는 압전기 직접효과와 압전기 역효과가 있다. 전자의 압전기 직접효과란 압전소자에 외부응력, 진동변위 등을 가하면, 그 출력단에 전기 신호가 발생하는 현상을 말한다. 또한 후자의 압전기 역효과란 압전소자에 외부로부터 전압을 가하면 소자가 기계적 변위를 일
