Let's see the process flow of cellulosic ethanol which we are interested in(Figure 1). At the upstream, biomass harvest undergoes a pretreatment and cellulose hydrolysis by enzymes and then fermented to ethanol through the points. The initial contract for each course are as follows.

Abstract
Bioethanol is one ofthe alternative sources of oil resources which received attention with biodiesel. Many countries produce bioethanol from food sources such as corn and sugarcane, but it causes food-energy conflicts and farmland problem. So it needs to focus on new biomass which is sustainable, renewable, cost-effective and do not occurred any conflicts. Algae are one ofthe bioma
the growth of a particular crystallographic direction. Among the shapes whi- ch can be obtained, rod-like gold nanostructures have been observer or synthesized using various chemical approaches. In this paper, we report the successful aspect ratio control of gold nanorods by the seed-mediated method, along with an improvement in the yield. Two major parameters were controlled to optimize the grow
