An ab initio variable-cell-shape molecular-dynamics algorithm is used to investigate the stability of three carbon nitrides with composition ${\mathrm{C}}_{3}$${\mathrm{N}}_{4}$. The hexagonal \ensuremath{\beta}-${\mathrm{C}}_{3}$${\mathrm{N}}_{4}$ structure, which has been the subject of earlier investigations, is re…

Owing to the steric bulk of the tert-butyl groups, the reactivity of the novel porphyrin 1, which has a nonplanar macrocyclic framework, deviates distinctly from that of any other known porphyrin. For example, prolonged treatment of 1 in HClO4/MeOH leads to formation of 5,15-dihydroporphyrin (“porphodi-methene”) 2.
The triplet lifetimes of the ethynyl-bridged binuclear RuII complexes 1 (m = 0, 1; n = 1, 2) are significantly longer than that of the parent mononuclear complex, despite much lower triplet energies. This effect, which arises from electron delocalization over an extended π* orbital, decreases upon removal of the secon…
Brizziite is a new sodium antimonate mineral from the Cetine mine, Tuscany, Italy. It occurs as dense aggregates of platy {001} hexagonal crystals. Associated minerals are stibiconite and mopungite. The crystals, which are polysynthetically twinned, are colourless and transparent, with pearly lustre. Electron micropro…
The white mica crystallinity index has been analyzed as a function of the following parameters: 1) the domain size, 2) lattice distortion, and 3) the presence of other phyllosilicates overlapping the 10 A XRD peak, particularly I/S mixed-layer. (2) is determined by the variance method suggested by Wilson (1963) and su…

The structures of the major folding intermediate, the transition state for folding, and the folded state of barnase have been previously characterized. We now add a further step toward a complete picture of the folding of barnase by reporting the backbone 15N, 13C, and 1H NMR assignments for barnase unfolded at pH 1.8…
We have cloned a mouse cDNA that is a member of the Krox gene family and encodes a protein we have named c-Krox. The c-Krox protein contains three zinc fingers of the Cys2His2 type. c-Krox binds specifically to a guanine-rich cis-acting element present twice in the promoter element of the mouse alpha 1(I) collagen gen…
Abstract Di(2‐ethylhexyl), di(2‐octyl), dihexyl, and dibutyl furan‐2,5‐dicarboxylate were synthesized from furfural and characterized for their plasticizing abilities toward PVC by dynamic mechanical thermal analysis (DMTA) with di(2‐ethylhexyl) phthalate (DOP) as the standard of reference. DMTA gave values for the de…
Abstract Aluminum hydroxide was used as a reactive filler to elastomers prepared from poly(oxypropylene)glycol (PPG), 2,4‐tolylene diisocyanate (TDI), and 1,4‐butane diol (BD). Mechanical properties, dynamic mechanical properties, and thermal properties were measured. Morphologies were observed by use of X‐ray diffrac…
Abstract The crystallization and melting behaviors of poly(aryletheretherketone) (PEEK) films were investigated, using differential scanning calorimetry and metallurgy concepts. The shape of the time–temperature–transformation (TTT) diagram, established for PEEK, results from both nucleation and growth phenomena. The…
