We have postulated that the toxic neuropathies associated with neurofilament-filled axonal swellings have a common pathogenesis, the covalent crosslinking of neurofilaments during anterograde transport. The newly described gamma-diketone, 3,4-dimethyl-2,5-hexanedione

Metal-free core-shell structured N-doped carbon/carbon …

1/9/2019· Interestingly, a recent study reveals that the N-doped carbon/carbon heterojunction in carbon fibers can enhance the CO 2 capture and sensing []. The microporous carbon fibers with N-doped heterojunction despite their overall low nitrogen content (<0.5 wt%) displayed exceedingly high CO 2 uptake (6.9 mmol g −1 at 1 bar, 273 K) and detection sensitivity (ΔR/R 0 peak = 2.85%).

A Medley of Potpourri: Carbon (updated)

Carbon (from Latin: carbo "coal") is a chemical element with syol C and atomic nuer 6. It is nonmetallic and tetravalent—making four electrons available to form covalent chemical bonds.It belongs to group 14 of the periodic table. Three isotopes occur naturally, 12 C and 13 C being stable, while 14 C is a radionuclide, decaying with a half-life of about 5,730 years.
