Although fullerenes were discovered nearly 35 years ago, scientists still struggle to isolate "single molecule" tubular fullerenes larger than C90. In similar fashion, there is a paucity of reports for pristine single-walled carbon nanotubes (SWNTs).

In this study, mono- and pentacyclic C(35) terpenes from Bacillus subtilis were biosynthesized via the cyclization of C(35) isoprenoid using purified enzymes, including the first identified new terpene cyclase that shows no sequence homology to any o

The MM3 force field has been extended to cover aromatic heterocycles of the pyridine and pyrrole types. Structures (32 compounds), heats of formation (35 compounds), dipole moments (35 compounds), and vibrational spectra (11 compounds) have been exam

Previous results led to the conclusion that the last step of biotin biosynthesis, the sulfuur insertion into dethiobiotin should involve a thiol as intermediate. The three possible thiols have been synthesized and their biological activity was evalua

Changes in quadrupole relaxation rates of 23 Na on addition of the Cl - salts of Na + , K + , Rb + Cs + , TMA + , and TEA + ions were used to determine the relative affinities of these cation for micells composed of the decyl phosphate monoanion, DPH

The structural evolution of negatively charged gold clusters (Au(n)(-)) in the medium size range for n = 27-35 has been investigated using photoelectron spectroscopy (PES) and theoretical calculations. New PES data are obtained using Ar-seeded He sup

The hydrogen-bonded dimer CH 3 NC...HCl has been isolated in a pulsed jet by keeping the reactive components CH 3 NC and HCl separate until the point at which they expand into the evacuated Fabry-Perot cavity of a pulsed nozzle Fourier-transform micr

A convergent asymmetric synthesis of the polyether antibiotic ferensimycin B has been completed. Chiral enolate bond constructions were employed to establish seven of the 16 stereocenters of the subunits 35 and 52, which comprise the C& and CI&3 port

Oxidation potentials for 35 phenoxide ions and 3 naphthoxide ions have been combined with their pK HA values to estimated homolytic bond dissociation energies (BDEs) for the O-H bonds in phenols. Comparison with literature values shows that there is
