The amine-containing polysaccharide chitosan was selectively deposited onto patterned gold surfaces in response to an applied voltage. Standard microfabrication techniques were used to pattern gold onto silicon wafers, and these gold patterns served as templates for the electric field directed deposition of chitosan.…

It is shown that both structural phase transitions in Cd2Re2O7, which occur at T_{s1}=200 K and T_{s2}=120 K, are due to an instability of the Re tetrahedral network with respect to the same doubly degenerate long-wavelength phonon mode. The primary structural order parameter transforms according to the irreducible re…

Co-continuous structures can be regarded as the coexistence of at least two continuous structures within the same volume. Blends with co-continuous structures may combine the properties of both components in a favorable way, for example, mechanical moduli. This review article deals with the identification, characteriz…

The dynamic response of a titanium carbide (TiC)–carbon steel, ceramic-metal composite, was studied in planar impact experiments, using a copper impactor with velocity in the 80–450 m/s range. The composites were prepared by pressureless infiltration of TiC ceramic preforms by molten steel. The metallic component had…

The synthesis and characterization of a new constrained tetraazamacrocyclic ligand, 1,4,8,11-tetraazabicyclo[9.3.3]heptadecane (1,11-C(3)-cyclam), is reported. Because of its basicity, this ligand (pK(a) of the protonated form >13.5) requires aprotic solvents for its metalation reactions. Two complexes of this ligand,…
