We investigate the dielectric and electrical properties of sol-gel/DNA-CTMA blends, with particular interest in capacitor applications in energy storage. Methacryloyloxypropyltrimethoxysilane (MAPTMS) was the solgel precursor, and DNA-CTMA was blended in to the resulting sol-gel at various weight percentages. The blen…
SALOME (an acronym for Small Angle Lab Operation Measuring Equipment) is a versatile, energy-dispersive x-ray diffraction imaging (XD<i>i</i>) test-bed facility commissioned and supported by the Transportation Security Laboratory, Atlantic City, USA. In work presented here, the Inverse Fan-beam (IFB) topology has been…
Abstract The contact metallization to n ‐type diamond is a key subject for realizing diamond bipolar devices. We have proposed the selective growth technique using the patterned surface morphology and 〈111〉 directional growth, and have achieved the heavily P doping even on (001) diamond. The objective of this research…
Nanoparticles of Co 0.5 Zn 0.4 Cu 0.1 Fe 2 O 4 were prepared by a combination of sonochemical and standard coprecipitation methods. The as-prepared samples were heat treated at four different temperatures to obtain particles of different sizes. The formation of the nanocrystalline phase has been confirmed by X-ray dif…
Abstract Poly(methyl methacrylate) (PMMA) and PMMA copolymers derived from plant oils (Polylinseed oil‐ g ‐PMMA, Polysoybean oil‐ g ‐PMMA, Polylinoleic acid‐ g ‐PMMA (PLina‐ g ‐PMMA) and Polyhydroxy alkanoate‐ sy‐ g ‐Polylinoleic acid‐ g ‐PMMA (PHA‐ g ‐PLina‐ g ‐PMMA)) as hydrophobic polymers, a series of hydrophobic…
The development of low cost, scalable, renewable energy technologies is one of today's most pressing scientific challenges. We report on progress towards the development of a photoelectrochemical water-splitting system that will use sunlight and water as the inputs to produce renewable hydrogen with oxygen as a by-pro…
Shape memory alloys (SMAs) belong to 'intelligent' materials since the metal alloy can change its macroscopic shape as the result of the temperature-induced, reversible martensite-austenite phase transition. SMAs are often applied for medical applications such as stents, hinge-less instruments, artificial muscles, and…
Abstract In this work, typical ternary blends of three versatile polymers—polyamide 6, a propylene–ethylene copolymer ( co ‐PP), and polystyrene—were studied. As a compatibilizer, co ‐PP with randomly dispersed minor ethylene units was multimonomer‐melt‐grafted in the presence of maleic anhydride, styrene, and dicumyl…
The conductivity of graphite is analytically evaluated in the range of 0.1--1.5 eV, where the electron relaxation processes can be neglected and the low-energy excitations at the ``Dirac'' points are most essential. The value of conductivity calculated per one graphite layer is close to the universal conductivity of g…
Materials used as luminescent down shifters (LDS) have to absorb light effectively in the spectral area where solar cells have poor internal quantum efficiency. At the same time these materials have to emit most of the absorbed spectral powers at lower energies where the internal quantum efficiency of the solar cell i…
We report on an unusual crystallization phenomenon that results in the self-assembly of sub-micron tubules of crystalline SrTiO(3). The deposition of the tubular structures was done in the pores of anodized aluminum oxide templates by the electrophoretic deposition of SrTiO(3) sols and subsequent annealing. Homogeneou…
Plasmonic materials have conventionally been gold and silver in optical frequencies. However, these conventional metals in the near-infrared (NIR) and visible spectral ranges suffer from problems such as large losses. With the advent of metamaterials, these metals pose a serious bottle-neck in the performances of meta…
Although plasmonic nanoparticles are widely utilized in spectroscopy and sensing applications, a quantitative structure-function relationship is lacking. In this proceeding, we discuss measurements of single noble metal nanoparticles using localized surface plasmon resonance (LSPR) spectroscopy, surface-enhanced Raman…
Abstract To investigate heat transport across a biological membrane, we performed a series of reverse nonequilibrium molecular dynamics (RNEMD) simulations on a model dipalmitoylphosphatidylcholine (DPPC) bilayer system at the atomistic level. In a detailed analysis of the initially irritating results, we show how and…
The four-layer superstructure of basic Co-rich decagonal ${\text{Al}}_{72.5}{\text{Co}}_{18.5}{\text{Ni}}_{9}$ was determined by single-crystal x-ray diffraction. Based on our previous work [A. Strutz, A. Yamamoto, and W. Steurer, Phys. Rev. B 80, 184102 (2009)], a superstructure model was derived with five-dimensiona…
The self-assembling behavior and microscopic structure of zinc oxide nanoparticle Langmuir-Blodgett monolayer films were investigated for the case of zinc oxide nanoparticles coated with a hydrophobic layer of dodecanethiol. Evolution of nanoparticle film structure as a function of surface pressure (π) at the air-wate…
Layered ZnO microspheric particles were prepared by the thermal decomposition of layered hydrozincite (LZnHC), which was synthesized from zinc nitrate and urea in a water/PEG400 mixture. The influence of the starting reagents, their concentrations, and the amount of PEG in the water/PEG400 mixture on the particle grow…
We present a study of the relaxation dynamics of the photoexcited conductivity of the impurity states in the low-density electronic glass, phosphorous-doped silicon Si:P. Using subband gap optical pump-terahertz probe spectroscopy we find strongly temperature- and fluence-dependent glassy power-law relaxation occurrin…
The control of the wettability by nanoparticles (NPs) was studied by treating lignin model surfaces with silica NPs at various NP concentrations. The experimental contact angles (CAs) were compared to a modified Wenzel equation, which takes into account the changes in the effective surface area and the surface roughne…
Abstract PP/organoclay nanocomposites were prepared using different processing aids (EMCA and PPG), and their effects on the thermal and mechanical properties were evaluated by WAXD, TEM, SEM, DSC, and mechanical tests. This study helps to clarify the effects of processing aids on the organoclay surface and on the int…
