“…(2002) and Orlov et al . (2018) described and illustrated an age determination method based on counting otolith growth zones, and the present approach was compatible with that. For all species in the present study, including C. rupestris and M. berglax , a consistent counting procedure had to be developed based on a common understanding among readers of what patterns should be accepted as annuli.…”

“…(2002) and Orlov et al . (2018) to determine age, and the approaches were well described and illustrated. In the present study, relatively clear, gradually narrowing growth increments from the centre to the otolith margin were found on otolith sections from the entire size range of all the seven species aged.…”

“…(2002) but were high compared with data from West Greenland waters provided by Orlov et al . (2018). Judging from illustrations in these published accounts, the methods used for age determination by different workers appeared to correspond to those used here, but as yet no intercalibration exercises have been published for the species.…”

Nineteen species of the deep‐water fish family Macrouridae inhabit the Mid‐Atlantic Ridge (MAR) of the North Atlantic. Size and age structure, longevity and length at age were explored for seven of the more abundant species: Coryphaenoides armatus, Coryphaenoides brevibarbis, Coryphaenoides carapinus, Coryphaenoides guentheri, Coryphaenoides mediterraneus, Coryphaenoides rupestris and Macrourus berglax. The otoliths from these species had growth increments resembling those accepted as annuli in other deep‐water species for which validation experiments have been conducted. Based on the counts of these growth increments, age estimates were derived as the basis for studies of age structure, growth and longevity. All the species appeared to have relatively low growth rates, but the interspecific variation in longevity illustrates that there is a considerable variation within the family and among species inhabiting the same deep‐sea environment. Most of the species likely complete full life cycles on the MAR, but it is probable that both the youngest and the largest‐oldest individuals of some of the species were not sampled adequately.

“…Incorporating C 60 into an oligomer may permit stabilization of the active layer. Moreover, the creation of a metal‐free method of polymerizing C 60 would expand possibilities for its use in anti‐cancer and anti‐viral treatments, as it would make possible the exploration of poly(fullerene) nano‐ and mesostructures such as micelles and vesicles …”

For the first time, imino chemistry is explored for the synthesis of main chain fullerene oligomers and low‐molecular‐weight polymers. Oligo(aziridinofullerene)s and low‐molecular‐weight poly(aziridinofullerene)s (PAFs) are prepared by 1,3‐dipolar cycloadditions of bis(azidoalkyl) comonomers to C60. The effect of the steric bulk of the comonomer is studied and it is found that PAF solubilities and molecular weights are increased with longer comonomer side‐chains. Initial and promising photovoltaic characterizations show commensurate improvements in properties. Interestingly, the PAFs exhibit lowest unoccupied molecular orbitals close to those of phenyl‐C61‐butyric acid methyl ester. Routine characterizations are correlated with DFT/B3LYP/6‐31G(d) to understand structural and electronic behaviours. It is expected that higher molecular weights may be obtained through comonomer variations and that this novel methodology will open a route to interesting materials for optoelectronics. © 2017 Society of Chemical Industry
