Diffraction from carbon nanofiber arrays.
A square planar photonic crystal composed of carbon nanofibers was fabricated using e-beam lithography and chemical vapor deposition. The diffraction properties of the system were characterized experimentally and compared with theory and numerical simulations. The intensities of the (-1,0) and (-1,-1) diffraction beams were measured as functions of the angles of incidence for both s and p-polar...
متن کاملPreparation and Characterization of Activated Carbon derived from olive stone as adsorbent for Congo Red
Carbon activated powdered was prepared from activated carbon derived from olive stone. Then byusing the surface methodology, many parameters such as pH, furnace temperature (T), acid ratio,time of activation that affect on the qualities prepared activated carbon produced and its efficiencywere investigated. In addition, the adsorption of Congo Red onto the activated olive stone carbonactive was...
متن کاملSmall-Scale Batch Fabrication and Characterization of Carbon Nanofiber Probes
Due to their high aspect ratios, nanoscale tip radii, high chemical stability and high mechanical strength, carbon nanotubes (CNTs [1]) and carbon nanofibers (CNFs) are thought to be an ideal probe for scanning probe microscopes (SPMs). Thus, much effort has been devoted to fabricate CNTor CNF-based SPM probes since the discovery of CNTs [2]. Nevertheless, the batch fabrication of CNTor CNF-tip...
متن کاملSynthesis and characterization of potassium metal/graphitic carbon nanofiber intercalates.
Direct reaction of herringbone, platelet, or narrow, tubular herringbone graphitic carbon nanofibers (GCNFs) with molten potassium gives K/GCNF intercalates with stoichiometric control of potassium loading. Intercalate formation is confirmed by powder X-ray diffraction and micro-Raman spectroscopy. K/GCNF intercalates act as radical-anion alkene polymerization catalysts and reduce water with st...
متن کاملPreparation and characterization of activated carbon from rice bran.
A study on the preparation of rice bran-based activated carbon was conducted, with and without an acid treatment step prior the activation process. The influence of the activation time on the structure of the activated carbons was evaluated. The acid treatment had a significant positive influence on sorption properties. The rice bran-activated carbon presented a BET surface area of 652m(2)g(-1)...
