Quasi-symmetric triangle-free designs D with block intersection numbers 0 and y and with no three mutually disjoint blocks are studied. It is shown that the parameters of D are expressible in terms of only two parameters y and m, where m = k/y, k being the block size. Baartmans and Shrikhande prove
## Abstract Crystalline helical carbon nanotubes (HCNTs) are synthesized as the main products in the pyrolysis of acetylene at 450โยฐC over Fe nanoparticles generated by means of a combined solโgel/reduction method. Transmission electron microscopy (TEM) images reveal that there are two HCNTs attach
