Carbon foams are hypothetical carbon allotropes that contain graphitelike ($s{p}^{2}$ carbon) segments, connected by $s{p}^{3}$ carbon atoms, resulting in porous structures. In this work the density-functional-based tight-binding method with periodic boundary conditions was employed to study the energetics, the stabil…

Abstract Single‐walled carbon nanotubes (SWNTs) are functionalized through both covalent and noncovalent bonding approaches to enhance dispersion and interfacial bonding. The coefficient of thermal expansion (CTE) of the functionalized‐SWNT‐reinforced epoxy composites are measured with a thermal mechanical analyzer (T…

The properties of Cu$_{x}$TiSe$_{2}$ are studied by band structure calculation based on the density functional theory for supercells. The density-of-states (DOS) for $x$=0 has a sharply raising shoulder in the neighborhood of the Fermi energy, $E_F$, which can be favorable for spacial charge modulations. The Cu impuri…

The dependence of thermally induced spontaneous magnetization reversal on time-dependent cooling protocols was studied. Slower cooling and longer waiting close to the Nèel temperature of the antiferromagnet ($T_N$) enhances the magnetization reversal. Cycling the temperature around $T_N$ leads to a thermal training ef…

Porous carbons with large meso/macropore surface areas were prepared by the colloidal-crystal-templating technique. The porous carbons exibited extremely high specific electrochemical double layer (EDL) capacitance of 200−350 F g -1 in an aqueous electrolyte (1 M H 2 SO 4 ). The pore structure dependence of the capaci…

Layered perovskite La2CuO4+delta(LCO) thin films were epitaxially grown on SrTiO3 (STO) and LaSrAlO4 (LSAO) substrates by atomic-layer-by-layer molecular beam epitaxy. The lattice de-fects and residual strain in these films were investigated by means of transmission electron mi-croscopy and electron energy loss spectr…

Abstract Polymer brushes have recently emerged as an extremely versatile way to modify surface properties in a robust and controlled way. The introduction of responsive polymers and block copolymers in polymer‐brush systems has also opened up new routes to ‘smart' surfaces with switchable surface properties. Here, the…

Abstract Summary: More than twenty years have passed since we invented PCN, in which only a few wt.‐% of silicate is randomly and homogeneously dispersed in the polymer matrix. When molded, these nanocomposites show superior properties compared to those of pristine polymers. The number of papers on PCN has increased r…

In this paper, current-time transient (CTT) forms associated with the two remaining models of two-phase growth are identified. The first model represents a scenario in which growth centers associated with the phase with the higher outward growth rate are conically shaped, while the shape of the remaining growth center…

Amplified spontaneous emission (ASE) characteristics of a blue dye coumarin 151 encapsulated in a highly ordered mesoporous SBA-15 were studied. The spectra narrowing was observed and found that the threshold and loss were greatly reduced, and the gain is significantly increased compared with spin-coated coumarin 151…

Ultralow- integration issues for node and below is a major challenge. Pore creation was studied vs the matrix film cross-linking. After curing at low temperature some bumps were found dispersed at the top of the film surface. The porosity could be changed by varying the porogen loadings and curing program ramp. At hig…
