The present work investigates the structure of large polystyrene (PS) chains in solutions of small poly(ethyl methacrylate) (PEMA) microgel particles in toluene. Toluene is a good solvent for the PS chains. The PEMA colloids have an outer radius of R=11 nm which is much smaller in size than the radius of gyration Rg=5…

We describe time-of-flight secondary ion mass spectrometry (SIMS), depth profiling, and atomic force microscopy studies of nanoporous silica (NPS) ultralow-k (ULK) dielectric films after C4F8∕90% Ar plasma etching. The goal of this work was to establish the role of materials chemistry and porosity on determining the c…

Spectral selectivity based on tuning the surface plasmon resonance in metallic nanoshells by variation of the relative shell thickness is shown to be limited by the interplay between scattering and absorption. To achieve resonance energies in the near infrared and infrared, relatively large cores are needed, which lea…

Polarized infrared (IR) spectroscopy has been used to determine the crystalline and amorphous orientation of polyamide fibers. The transition moment angle of the band at 936 cm-1 of PA66 was determined to be 48 degrees using IR spectroscopy and birefringence measurement. The crystalline orientation of PA66 fibers was…

Ideally ordered DNA nanopatterns have been formed by selectively opening holes in a barrier layer covering gold-filled anodic porous alumina, and then adsorbing thiolated DNA onto the exposed gold nanodisks. Fluorescence microscopy of fluorescent-dye-labeled thiolated DNA fixed on the gold-disk array confirms the sele…

Epitaxial Pt films with (111) and (100) orientations were grown on Y 2 O 3 -stabilized ZrO 2 (YSZ)-covered (100)Si substrates by RF sputtering. (111)Pt films were epitaxially grown on (100)YSZ∥(100)Si substrates at 580 and 680°C, but competitive crystal orientations of (111) and (100) at 780°C. In contrast, a (100)-or…

The structure of the complex between the minor groove binder netropsin and d(GGCCAATTGG) was determined via single-crystal X-ray techniques. The structure was refined to completion using refmac5.1.24, resulting in a residual R-factor of 20.0% (including 68 water molecules). Using crystal engineering and cryocooling te…

Four polyethylene glycol (PEG)/2,4-toluene diisocyante (TDI)/ perfluorinated aliphatic alcohols mixture (F6) adducts were prepared by reacting equimolar ratios of PEG (300, 600, 1000, or 2000), TDI, and F6 at 90°C for 90 min. All adducts, except that based on PEG 300 were water dispersible. These dispersions were used…

We have investigated the dynamics of phenylene rings in glassy bisphenol-A (BPA) polycarbonate (PC) by means of quasielastic neutron scattering. Taking advantage of selective deuteration of the samples, we have studied the incoherent scattering of hydrogens in phenylene rings on the one hand, and on the other hand the…

We provide a fabrication method for silver nano-particles with a uniform particle size using vacuum deposition. The size uniformity was controlled by a small amount of neodymium–copper (Nd–Cu) as a co-sputtered material. Particles with a size of 20 ± 7 nm dispersed in a SiO 2 matrix have been obtained.
