By using non-reactive sputter deposition at low temperatures metastable solid solution phases in the Ti–Ni–C system were synthesized. Produced thin films were either single phase carbides or nanocomposite of nanocrystalline carbide and amorphous C. In the Ni-containing samples a supersaturated solid solution phase (Ti…
This paper describes the formation of Cu nanofilms on a Ru/Ta-coated wafer using electrochemical atomic layer deposition (E-ALD). The initial steps involved cleaning and oxide removal from the Ru/Ta substrate using ultrahigh vacuum electrochemical system. Auger spectroscopy was used to follow the relative amounts of o…
Current use of TBCs is subjected to premature spallation failure mainly due to the formation of thermally grown oxides (TGOs). Although extensive research has been carried out to gain better understanding of the thermo - mechanical and -chemical characteristics of TBCs, laboratory-scale studies and simulation tests ar…
Myocardial cell injection and tissue engineering could provide novel treatment options for heart diseases; however both approaches are limited by the loss of the transplanted myogenic cells. We hypothesized that novel hydrogels could promote cardiomyocyte survival and remedy this critical limitation. The hydrogel desc…
The enthalpies of combustion and formation of S-lactic acid at 298.15 K, Δc H m o (cr.) = −1337.9 ± 0.8 and Δf H m o (cr.) = −700.1 ± 0.9 kJ/mol, were determined by calorimetry. The temperature dependence of acid vapor pressure was studied by the transpiration method, and the enthalpy of its vaporization was obtained,…
We present plasmonically-enhanced photoconductive antenna arrays and experimentally demonstrate enhanced light localization into device dimensions less than one-tenth of the wavelength. We present the fabrication and characterization of the device.
Poly(3-alkylthiophene) formed regular, layered arrays and showed liquid crystalline structures in the solid state. To elucidate the nanophase segregation in poly(3-alkylthiophene)/fullerene blends, X-ray diffraction, atomic force microscopy, scanning electron microscopy, and polarized optical microscopy were conducted…
During two-dimensional chiral conglomerate formation of tartaric acid on the copper(110) surface, the growth of one enantiomorph is suppressed by the opposite chirality of a coadsorbed malic acid enantiomer, forming a quasi-racemic, semi-ordered mixture.
A carbon-coated mesoporous solid solution with an olivine structure has been synthesized. Capacities of at 1/20C and at 2C were achieved at room temperature. A two-phase and a single-phase solid solution mechanism were found for the reactions of and , respectively, based on the galvanostatic intermittent titration tec…
This chapter provides historical background and a foundation for the other chapters in this book by reviewing the most closely related research and developments in nanoscale materials in chemistry and their environmental applications. The review includes nanoscale sorbents, destructive sorbents, nano-catalysts, and ph…
158 P-containing fertilizers, standard mineral and recycling products, were analyzed for their chemical solubility using 10 different methods.Correlations between methods were highly significant, indicating that a reduction of official methods is viable.A modified Neubauer pot trial was carried out with different P-re…
Carburization-Enhanced Passivity of PH13-8 Mo: A Precipitation-Hardened Martensitic Stainless Steel, Heuer, A. H., Kahn, H., O'Donnell, L. J., Ernst, F., Michal, G. M., Rayne, R. J., Martin, F. J., Natishan, P. M.
Short linear motifs (SLiMs) in proteins can act as targets for proteolytic cleavage, sites of post-translational modification, determinants of sub-cellular localization, and mediators of protein-protein interactions. Computational discovery of SLiMs involves assembling a group of proteins postulated to share a potenti…
Interaction of apohemoprotein with a covalently immobilized heme moiety onto a gold nanoparticle surface resulted in supramolecular hemoprotein-gold nanoparticle conjugates. The addition of an apohemoprotein dimer further led to a densely-packed hemoprotein-gold nanoparticle assembly, which was visualized by TEM and A…
Controlling the morphology in bulk-heterojunction solar cells is the preferred and most effective way to achieve high efficiency. To control the morphology, we synthesized a novel hydrophobic end-functionalized P3HT to induce hydrophilic–hydrophobic repulsive interactions in the boundary between the relatively hydroph…
A simple photoelectrochemical method is developed to measure the intrinsic electron transport resistance (R(0)) of TiO(2) photoanodes. R(0) is considered as the sum of electron transport resistance at the TiO(2)/FTO interface and among TiO(2) nanoparticulates during electron transport process, which is independent of…
TiO2 based photocatalytic coatings are currently restricted to outdoor applications due to the requirement of UV light. Nitrogen doping of TiO2 was used here to activate them in indoor conditions for self-cleaning applications. We developed an original process, allowing nitridation of anatase nanoparticles dispersed w…
Since its invention in 1986 by Binnig, Quate, and Gerber, the atomic force microscope (AFM) has proven to be an extremely useful tool for examining the interactions of proteins with surfaces. Fibrinogen in particular has been used as a model protein to demonstrate new methodologies for studying protein behavior with A…
Three unprecedented metal-organic frameworks [M3(tib)2(CTC)2]·nH2O [M = Co(II), n = 2 (1); Mn(II), n = 2.92 (2) and Ni(II), n = 2 (3)] based on M3(OCO)6 trinuclear secondary building units (SBUs) have been successfully synthesized by reactions of corresponding metal salt with mixed flexible triacid of 1,3,5-cyclohexan…
As the field of protein structure prediction continues to expand at an exponential rate, the bench-biologist might feel overwhelmed by the sheer range of available applications. This review presents the three main approaches in computational structure prediction from a non-bioinformatician?s point of view and makes a…
