I never read Twenty Major nor do I plan to purchase his book because well i just don’t get it. But it is good to see that the blogosphere has more physicists in it. Also I can reveal Twenty’s real name. Dachi Yang. Here is an extract from his paper (Acedemic Subs required).
Electrochemical synthesis of metal and semimetal nanotube–nanowire heterojunctions and their electronic transport properties
Here, we demonstrate a facile approach for the building of metal and semimetal nanotube–nanowire (NT–NW) nanoheterojunction arrays by sequential electrochemical deposition of two materials inside the nanochannels of anodic aluminium oxide (AAO) template. Herein we take metal Cu and semimetal Bi as examples. The heterojunction arrays of Cu NTs and Bi NWs (CuNT–BiNW) are achieved by electrochemical deposition of Cu first, and then Bi in the nanochannels of the AAO template with one side coated with an Au layer which is thin enough to leave the pores open and cover only the top surface of the pore walls, as is shown schematically in the ESI.{ Similarly, if the electrodeposition sequence is changed to Bi first and then Cu, in this case heterojunction arrays of Bi NTs and Cu NWs (BiNT–CuNW) can be achieved (see ESI{). As for the CuNT–BiNW heterojunction arrays, Fig. 1(a) and (b) reveal the SEM images of the BiNWs segment and the CuNTs segment, respectively, after the template was partially removed. Both the CuNTs and the BiNWs have an outer diameter about 80 nm, in agreement with that of the nanochannels in the AAO template. Fig. 1(c) shows a side-view SEM image of a bundle of CuNT–BiNW heterojunctions after the AAO template was completely removed. The three dashed circles marked I, II and III are the BiNWs segment, junction area and CuNTs segment, respectively, which have been further confirmed by the corresponding EDS analyses shown in Fig. 1(d), (e) and (f), respectively. It can be seen that the CuNTs (marked by dashed circle III) are quite uniform with smooth surface, while the BiNWs (dashed circle I) are not so uniform with rough surface.
And it goes on CuNT is named about 59 times. Shame about it being known for the acronym it seems an interesting piece of work.
