Nanostructured carbon materials, including carbon nanotubes, graphene and nanoporous carbon, show promise for expanding renewable energy. In particular, the configuration and electronic properties of graphene edges in relation with their electrochemical activity have become a major issue in carbon-based energy storage devices. Here, we review recent results concerning the important roles of graphene edges as the gateway for lithium ion intercalation in the anode of lithium-ion batteries, as promoters of high capacitance in carbon-based supercapacitors, and as anchoring sites for Pt nanoparticles in fuel cells. We envisage that the controlled synthesis of a specific, clean, and stable edge configuration could be achieved to maximize the electrochemical performance of nanostructured carbon-based energy storage devices.

Nanoscale defects in the outer tube to preserve the electrical and optical features of the inner tube can be engineered to exploit the intrinsic properties of double walled carbon nanotubes (DWCNTs) for various promising applications. We demonstrated a selective way to make defects in the outer tube by the fluorination of DWCNTs followed by the thermal detachment of the F atoms at 1000 °C in argon. Fluorinated DWCNTs with different amounts of F atoms were prepared by reacting with fluorine gas at 25, 200, and 400 °C that gave the stoichiometry of CF0.20, CF0.30, and CF0.43, respectively. At the three different temperatures used, we observed preservation of the coaxial morphology in the fluorinated DWCNTs. For the DWCNTs fluorinated at 25 and 200 °C, the strong radial breathing modes (RBms) of the inner tube and weakened RBms of the outer tube indicated selective fluorine attachment onto the outer tube. However, the disappearance of the RBms in the Raman spectrum of the DWCNTs fluorinated at 400 °C showed the introduction of F atoms onto both inner and outer tubes. There was no significant change in the morphology and optical properties when the DWCNTs fluorinated at 25 and 200 °C were therm..ly treated at 1000 °C in argon. However, in the case of the DWCNTs fluorinated at 400 °C, the recovery of strong RBms from the inner tube and weakened RBms from the outer tube indicated the selective introduction of substantial defects on the outer tube while preserving the original tubular shape. The thermal detachment of F atoms from..luorinated DWCNTs is an efficient way to make highly defective outer tubes for preserving the electrical conduction and optical activity of the inner tubes.

This study investigated distribution of HlA alleles (HlADRB1*01, *03, *04, *07, HlA-DQB1*0201, *0301/4) in 34 healthy controls and 57 rheumatoid arthritis (RA) patients in a Bangladeshi population and correlated the genotypic frequencies with clinical parameters. Frequency distribution of HlA-DRB1*04 (34%) and HlA-DRB1*01 (32%) were the highest followed by HlA-DQB1*0301/4 (29%) and HlA-DQB1*0201 (26%) in RA patients while HlA-DRB1*03 (12%) had lowest frequency. Plasm..level of anti-CCP and rheumatoid factor antibodies confirmed diagnosis of RA patients that varied significantly between patients and healthy controls. likewise, plasm..levels of C-reactive protein, triglycerides, cholesterol, HDl-cholesterol and activities of AST and AlT exhibited significant variation between the two groups. In contrast, the levels of glucose, total protein, uric acid, lDl-cholesterol and plasma activity of AlP in RA patients had no significant deviations from healthy controls. Relationship between HlA genotype frequency and clinical parameters revealed that the mean levels of anti-CCP and rheumatoid factor antibodies were highest in the patients harboring HlA-DRB1*04 allele. These findings underpin the correlation between HlA genotype with clinical markers of RA which are indicative of disease severity. The positive correlation of these markers with certain HlA genes may be used to identify susceptible individuals who are likely to have RA in Bangladeshi population.
