and beads due to the agglomeration of MnO2 outside the NFs (as can be seen in Fig. 1c), for which the MnO2 nanoparti- cles hypothetically should be inside the NFs. In comparison, the SSA of the pristine ACNFs is higher because there are no beads that blocked the pores. Thus, for various reasons, the optimum metal oxide loading is worth investigating to obtain ACNFs with a high SSA. Table 2... In this study, composite PAN-based ACNFs embedded with MgO and MnO2 were prepared by the electrospinning method. The resultant pristine ACNFs, ACNF/MgO and ACNF/MnO2 were characterized in terms of their morphological changes, SSA, crystallinity and functional group with FESEM-EDX, the BET method, XRD and FTIR analysis, respectively. Results from this study showed that the SSA of the ACNF/MgO composite (1893 m2 g?1) is significantly higher than that of the pristine ACNFs and ACNF/MnO2 which is... -

in a dry atmosphere [14]. Agglomeration of graphene sheets affects the initial ca- pacitance because of a decrease in the active specifc surface areas that include a double layer capacitance. Fig. 3 shows the transmission electron microscopy and scanning electron microscopy images of Co3O4/graphene composites at differ- ent annealing temperatures. Annealing Co3O4/graphene sam- ples in air at... -

the particle size and diminutive metal agglomeration which was sporadically found in the sample (Fig. 3(g)-(i)). The Pt-Ru/CNT (4.0 M H2SO4-0.5R) catalyst shows slightly decrease in the particle size which was intermittently found in the sample (Fig. 3(f)). Over all catalysts synthesized using CNTs obtained after reflux at 90 oC show ample metal particle deposition on the CNT support, providing an... -

위해서 세포와 임플란트 표면의 나노구조의 상호작용에 대한 이해가 중요하다. 본 연구에서는 Sn를 촉매로 이용하여 Vapor-Liquid-Solid 법을 이용하여 $TiO_2$ 나노와이어를 튜브 전기로 안에서 질소기체 조건하에서 합성하였다. 이 때 촉매로 사용된 Sn 박막의 두께에 따라 응집된 나노스피어를 이용하여 $TiO_2$ 나노와이어의 크기를 조절하였다. 골융합을 위한 예비 실험으로써, 만들어진 $TiO_2$ 나노와이어 샘플 위에서 조골전구세포(pre-osteoblast)를 1주일간 배양하였고, 세포가 $TiO_2$ 나노와이어에 잘 결합함을 볼 수 있었다. -

lower surface area may be attributed to the agglomeration of GO layers during the drying process at 100°C, because of the unavoidable van der Waals force between each single sheet of GO. The results of the BET method showed that the specifc sur- face area of the MWCNTs and oxidized MWCNTs were 165 and 203 m 2 g 1, respectively. Also, the average pore diameter and pore volume were 29 nm and... Dyes are widely used in various industries including textile, cosmetic, paper, plastics, rubber, and coating, and their discharge into waterways causes serious environmental and health problems. Four different carbon nanostructures, graphene oxide, oxidized multi-walled carbon nanotubes, activated carbon and multi-walled carbon nanotubes, were used as adsorbents for the removal of Nile Blue A (NBA) dye from aqueous solution. The four carbon nanostructures were characterized by scanning electron...
