An unusual adduct, [{Pt 2 Ag 4 (C⋮C- t -Bu) 8 ·(bipy)}] ∞ ( 3 ), has been obtained from the reaction of the hexanuclear cluster [Pt 2 Ag 4 (C⋮C- t -Bu) 8 ] ( 1 ) with 2,2‘-bipy independently of the molar ratio (1:1 or 1:excess) employed. The crystal structure of 3 shows the presence of an extended polymeric chain cons…

In our current discussion of the thermodynamics and molecular kinetics of glass-forming liquids, the entropy is extrapolated below a liquid’s vitrification temperature Tg along a curve of progressively increasing slope until a temperature Tk is reached. Here the entropy and heat capacity, Cp, of the equilibrium liquid…

Two different polymorphic forms of free base phthalocyanine films have been grown on glass substrates by ultrahigh vacuum organic molecular beam deposition. Postgrowth annealing of films grown at room temperature leads to transformation from the α to the β 1 phase. The effects of annealing lead to a number of transiti…

We theoretically study the nonlinear optical response and photoexcited states of the Mott insulators. The nonlinear optical susceptibility χ^(3) is calculated by using the exact diagonalization technique on small clusters. From the systematic study of the dependence of χ^(3) on dimensionality, we find that the spin-ch…

The rheology of rigid rod cellulose whisker suspensions has been investigated. The isotropic-at-rest suspension flow curves show two plateaus, one at low shear rates and another at high shear rates, that reflect the flow of isotropic (at low shear rates) or oriented (at high shear rates) suspensions. From the low shea…

Sonoluminescence is the production of light from acoustically forced bubbles; sonochemistry is a related chemical processing technique. The two phenomena share a sensitive dependence on the liquid phase. The present work is an investigation of the fate and consequences of water vapour in the interior of strongly force…

Four years ago, the U.S. Environmental Protection Agency (EPA) ignited a fire storm when it declared that tens of thousands of people were dying each year from breathing tiny particles of dust and soot--and issued tough new regulations to crack down on these pollutants. Industry groups and many scientists assailed the…

The redox states of a series of well-defined hybrid dendrimers based on oligothiophene cores and poly(benzyl ether) dendrons have been studied using cyclic voltammetry and variable-temperature UV/visible/near-IR spectroscopy. The oxidation potentials and the electronic transitions of the neutral, singly oxidized, and…

Starlike HPMA copolymers were synthesized by conjugating semitelechelic poly[N-(2-hydroxypropyl)-methacrylamide] macromolecules (ST-PHPMA, arm) with PAMAM dendrimers (core: G2, G3, G4). ST-PHPMA was synthesized by chain transfer free radical polymerization, and the terminal -COOH was activated with N-hydroxysuccinimid…

Carbon nonotubes filled with long continuous cobalt nanorods or nanoparticles were synthesized by a simple catalytic process. Co(CO) 3 NO was used as the precursor and served as both the source for the carbon nanotubes and for the cobalt, the catalyst. Some nanotubes filled with nanorods have big heads. The Co-filled…

To clarify effects of crack speed and cross-link density on fracture energy of acrylamide gels, we evaluated the roughness of the fracture surface and measured the fracture energy taking into account the roughness. The fracture energy increases linearly with crack speed $V$ in a fast crack speed region, and the increa…
