CryoTEM demonstrates that a CNA35-bearing liposomal MRI contrast agent selectively binds to poorly assembled collagen type I as opposed to well-assembled collagen fibrils, whereas monomeric CNA35 binds to all forms of collagen. It is shown that upon conjugation to liposomes and micelles CNA35 loses its ability to diss…
We studied charge carrier trapping, detrapping, and recombination phenomena in ${\text{Ce}}^{3+}$ doped ${\text{YPO}}_{4}$, codoped with ${\text{Sm}}^{3+}$, ${\text{Dy}}^{3+}$, or ${\text{Tm}}^{3+}$. Ce ions trap the holes and Sm, Dy, and Tm trap electrons created during x-ray irradiation. By means of red to infrared…
Nanocomposites of biodegradable poly(butylene succinate) (PBS) and carbon nanofibers (CNFs) were prepared by three different methods, that is, solution blending, melt compounding, and solution and subsequent melt blending (SOAM) method, among which the SOAM method, where nano-scale fillers and polymer matrix are solut…
We have fabricated a series of superlattices composed of ${\text{V}}_{1\ensuremath{-}x}{\text{W}}_{x}{\text{O}}_{2}$ ($x=0$ or 0.08 with $1+2x$ $d$ electron per V atom) and ${\text{TiO}}_{2}$ (no $d$ electron) to investigate the interface and carrier-confinement effects of the metal-insulator phenomena of ${\text{VO}}…
Nanosized incubational domain was observed in 10 at.% gadolinium-doped ceria (GDC) using high-resolution transmission electron microscopy. Dislocations were extensively observed in 10 at.% GDC instead of heavily doped 25 at.% GDC. By Fast Fourier Transform and Inverse Fast Fourier Transform analysis, it was noticed th…
In this work, we present a theoretical framework that unifies polymer field theory and density functional theory in order to efficiently predict ordered nanostructure formation of systems having considerable complexity in terms of molecular structures and interactions. We validate our approach by comparing its predict…
The mechanism of hydrogen desorption from rutile TiO 2 (110)-(1 × 1) was studied by injecting electrons with controlled energy and flux into single surface hydroxyls (OH) in cryogenic scanning tunneling microscopy (STM). Desorption proceeds without a clear threshold already at much lower energies than reported previou…
The addition of a transmitted electron detector to a scanning electron microscope (SEM) allows the recording of bright and dark field scanning transmission electron microscope (STEM) images and the corresponding in-lens secondary electron images from the same region of a thin sample. These combined imaging techniques…
We report herein the synthesis and physicochemical characterization of eight new manganese-oxalato compounds with 1,2-bis(4-pyridyl)ethylene (bpe): {(Hbpe)(2)[Mn(2)(μ-ox)(3)]·∼0.8(C(2)H(5)OH)·∼0.4(H(2)O)}(n) (1), {[Mn(μ-ox)(μ-bpe)]·xH(2)O}(n) (2), [Mn(2)(μ-ox)(2)(μ-bpe)(bpe)(2)](n) (3), [Mn(μ-ox)(μ-bpe)](n) (4a and 4b…
Durable Au-patterning nanostructures with uniform spacing having an average nanoparticle size of 8 nm and an interparticle gap of 11 nm were fabricated using a microwave-plasma oven. Single molecules of immunoglobulin G (IgG) are individually occupied at the space constraints so that the extinction response of localiz…
We measured the electrical conductivity $(\ensuremath{\sigma})$ of ${\text{Fe}}_{0.96}\text{O}$ (FeO hereafter) at high pressures and temperatures up to 169 GPa and 2050 K, simultaneously with the synchrotron x-ray diffraction measurements. The results showed that a B8-structured FeO (B8 FeO) synthesized above 140 GPa…
Configuration of the surface atoms in aluminum clusters was investigated based on the structures with global minimum potential energy of some Al clusters in the size range of 270-500. The structures were optimized by the dynamic lattice searching with constructed cores (DLSc) method with the NP-B potential. In the opt…
Thermoplastic vulcanizates (TPVs) based on styrene-butadiene rubber (SBR)/ethylene-vinyl acetate copolymer (EVA)/high-impact polystyrene (HIPS) blends were prepared by dynamic vulcanization, and the TPVs was compatibilized by styrene-butadiene-styrene block copolymer (SBS). The effects of SBS compatibilizer on mechani…
Highly magnetic luminescent alginate-templated composite microparticles were successfully synthesized by a novel process combining emulsification and layer-by-layer self-assembly techniques. The composite microparticles were characterized by ζ-potential analyzer, transmission electron microscope, X-ray diffraction, Fo…
The geometry and three-dimensional (3D) morphology of the ceria particles synthesized by spray pyrolysis (SP) from two different precursors--cerium acetate hydrate and cerium nitrate hydrate (CeA and CeN ceria particles)--were characterized by transmission electron microscopy and electron tomography. Results were comp…
There are numerous reports of coumarin ester derivatives, in particular phosphate esters, as photocleavable cages in biological systems. Despite the comprehensive analysis of the photocleavage mechanism, studies of 4-methylcoumarin caged phosphates and/or nucleotides were always performed at constant pH. In this work,…
is one of the oxygen deficient ceramic materials widely investigated for both oxygen ion conduction and proton conduction in oxidizing atmospheres. However, its electrochemical properties have not been studied in hydrogen containing atmospheres. In this work, the electrical conductivity of in hydrogen containing atmos…
The biosynthetic shikimate pathway consists of seven enzymes that catalyze sequential reactions to generate chorismate, a critical branch point in the synthesis of the aromatic amino acids. The third enzyme in the pathway, dehydroquinate dehydratase (DHQD), catalyzes the dehydration of 3-dehydroquinate to 3-dehydroshi…
We analyze the influence of different bilinear terms giving rise to time-reversal invariant topological insulating phases in monolayer and bilayer graphene. We make use of the effective action formalism to determine the dependence of the Chern Simons coefficient on the different interactions and generalize the formali…
A hierarchical luminescent cellulose sheet was fabricated viaself-assembly of cadmium selenide (CdSe) nanoparticles capped with trioctylphosphine oxide (TOPO) and 1-hexadecylamine (HDA) onto ultrathin titania film pre-coated cellulose nanofibres of bulk natural cellulose substance (common commercial filter paper). Eac…
