Selective removal of metal cores from core–shell Ag@ZrO2 (ZrO2 coated Ag) and Au@ZrO2 (ZrO2 coated Au) nanoparticles result in stable and freely suspendable oxide nanobubbles of varying dimensions, both in thickness and in diameter. The metal core is removed by a newly found reaction in which halocarbons, generally ch…

A push-pull actuator for commanding the motion of the interphalangeal joints of anthropomorphic robotic hands is proposed. The actuator, based on coil springs, made of the shape-memory alloy Nitinol, is compact enough to be easily incorporated into the phalangeal structure of a robotic finger, thus eliminating the com…

The reaction of various highly substituted lanthanide(III) and -(II) aryloxide complexes with trimethylaluminum (TMA) was investigated. The solvent-free, π-arene-bridged dimers [Ln(OAr i Pr,H ) 3 ] 2, derived from the ortho- i Pr 2 -substituted aryloxide ligand OC 6 H 3 i Pr 2 -2,6, form bis-TMA adduct complexes, Ln(O…

The electromigration of Al-1%-Si interconnects under bidirectional (BC) and pulsed unidirectional (PDC) signals is discussed. The effect of signal asymmetry, duty cycle and frequency on the damage generation rate has been tested. The data suggests that the equivalent DC current of a non-DC signal is given by the avera…

A model of dipole fluid for ionic liquids similar to molten NaCl is proposed. The estimates for the critical parameters are obtained with the help of the van der Waals equation of state. The influence of the rotation on the characteristics of a dipole pair and the location of the critical point is discussed. The disso…

Abstract Depolymerization of the biopolymer chitosan by an autoclaving process at 121°C and 15 psi was investigated using various treatments. Acetic acid was found to be the most effective solvent in decreasing chitosan viscosity among the six organic acids tested. The rate of viscosity decrease increased with increas…

Conventionally, the addition of sesquioxide cation dopants to ceria has been thought of as a class of almost model systems. The most important defect mechanism involves simple anion vacancy charge compensation with those vacancy defects associating themselves with the trivalent cation and being distributed randomly th…

A hyperbranched aromatic poly(amide−imide) was prepared by the copolymerization of 4-(3,5-dicarboxyphenoxy)phthalic anhydride, a B‘B 2 type monomer, and 1,4-phenylenediamine, an A 2 type monomer. The rapid reaction between the anhydride and amino group led to the formation of the dominant imide intermediate which can…

Using density-functional theory we have calculated the equilibrium geometries and binding energies of a CO monolayer adsorbed on the nonpolar (1010) and the polar (0001)-Zn and (0001)-O surfaces of ZnO. Different adsorption sites and CO orientations were considered, and for the polar surfaces the influence of a hydrog…

Growth rates and morphologies of thin (0.1−2 μm) and thick (30 μm) films of miscible poly(ε-caprolactone)/poly(vinyl chloride) (PCL/PVC) blends have been investigated. Under isothermal crystallization, PCL growth rates decrease in blend films thinner than 1 μm. However, in pure PCL films, no growth rate dependence is…
