The hydrogen flow is always in a direction opposite the direction of the material being sintered so as to "sweep" the impurities away. Graphite boats are required and temperatures of between 2500° F and 2750° F are used. All small parts are packed in alundum (Al 2 O 3 ) grain. b) Combination Vacuum Sintering: Pre-sintering is done under inert gas or in vaccum at low temperatures until the

    data (Figure 5) shows indeed that the 2D band can be decomposed into four peaks (2L) and provides strong evidence in favor of multi-layer graphene as the major product. The ID/IG intensity ratio is widely used to assess the density of defects in graphite materials [29]. The D band of No.5 sample is rather uniform and near the noise level, indicating the NG remains a high crystalline quality. It is noted that the ID/IG for all samples in this work is much larger than that of CVD-grown graphene [15]

    In this experiment we tested to see if the catfish contained lead by using a lead testing kit. We used the data collected by ORNL in 2011 that is now accessible to the public. We pose that, if the age of the lake is older than the amount of lead will increase in the catfish when the amount of lead in the fish is a function of how old the lake is. Assuming the age of the lake would affect the amount of lead in the fish. The lakes that we picked were Tellico Lake, Melton Hill Lake, Watts Bar Lake
