Triple helical di-iron complexes, readily prepared through interaction of iron(II) ions with imine-based ligands, are cylinder-shaped tetracations comparable in size and shape to common protein DNA recognition units. They have a strong tendency to coil DNA, and have recently been found to induce formation of three-way…
Further studies on the fresh rhizomes of Polygonatum kingianum led to the isolation of one new spirostanol saponin (25R)-kingianoside G (1), and two pairs mixture of 25R and 25S stereoisomeric spirostanol saponins (25R, S)-pratioside D1 (2a, 2b) and (25R, S)-kingianoside A (3a, 3b), among them 2b and 3b were new spiro…
The steel industry is facing two difficult and urgent tasks to reduce CO2 emissions and to use low-grade iron resources effectively. The utilization of an iron ore–carbon composite is one of the promising methods to solve the former. The latter is concerning to goethite ores such as Australian Marra Mamba and pisolite…
ZnSe Nanowire Photodetector Prepared on Oxidized Silicon Substrate by Molecular-Beam Epitaxy, Hsiao, C. H., Chang, S. J., Wang, S. B., Chang, S. P., Li, T. C., Lin, W. J., Ko, C. H., Kuan, T. M., Huang, B. R.
Novel nanocomposites of NiO and polyoxometalate (Cs(2.5)H(0.5)PMo(12)O(40)) with particle sizes in the range of 5-10 nm showed exceptional oxygen and ammonia adsorption capabilities, and the nanocomposites catalyzed the oxidative dehydrogenation of propane and isobutane efficiently under mild conditions.
Magnetic nanoparticles have emerged as an important class of functional nanostructures with applications in various fields of biology and medicine. We have developed a simple synthetic route for functional Co nanoparticles which further allows their direct integration into Co@SiO2 microspheres, a synthesis that could…
We investigated area-selective atomic layer deposition (ALD) of zirconia using a self-assembled monolayer (SAM) and atomic force microscopy (AFM) oxidation lithography as a method of fabricating nanostructures. A SAM layer was used as a chemical mask for the ALD process, and AFM oxidation lithography was used as a nan…
Laser-induced blow-off from a tungsten surface that was exposed to helium plasma is investigated experimentally in the divertor simulator NAGDIS-II. The pulse width of the laser is submillisecond and is similar to the duration of type-I edge localized modes in ITER. The temporal evolution of blow-off particles, which…
The interaction of Pt with layers was investigated using photoelectron spectroscopy. Pt-doped layers 30 nm thick were deposited by radio-frequency (rf) magnetron sputtering using a composite target on a carbon diffusion layer of micropolymer membrane fuel cell covered by double-wall carbon nanotubes. The laboratory X-…
We describe a simple method of replica moulding to obtain novel 3D microstructured smart hydrogels based on protein polymers mimicking the structure and behaviour of the extracellular matrix (ECM).
In situ adipose tissue regeneration in fat tissue by collagen sponges and gelatin microspheres containing basic fibroblast growth factor (bFGF) was investigated. A minced collagen sponge scaffold (1 ml) was incorporated with microspheres containing 10 microg bFGF and administered into a defect of rabbit fat tissues. A…
A flexible and widely applicable method allows the deposition of carbon-doped visible light-activated photocatalytic TiO2 thin films on a variety of substrates.
ECE-pincer sulfato palladium complexes (pincer = [C(6)H(3)(CH(2)E)(2)-2,6](-); E = SPh (), SMe (), S(t)Bu (), NMe(2) ()) were synthesized and characterized. In the solid-state (X-ray determinations) and exist as neutral ECE-pincer palladium sulfato complexes with a mu(2)-O,O' bridging sulfato ligand. IR and Raman spec…
Ultrahigh-field (73)Ge NMR spectra and DFT calculations of GeO(2) phases reveal distinct parameters for four- and six-coordinate Ge, illustrating the viability of solid-state (73)Ge NMR for structural studies.
Carbon supported Pt 1 Ru 1 Ir x ( 0 ⩽ x ⩽ 2 ) nanoparticles were prepared by a coimpregnation reductive pyrolysis method and their electrocatalytic activity toward methanol electro-oxidation at 25, 40, and 60 ° C was investigated. The mass activity (current normalized by the mass of Pt) for methanol electro-oxidation…
Colloidal rods interacting with a temperature-dependant attraction are constructed by grafting the polymer poly(N-isopropylacrylamide) (PNIPAM) to the surface of the charged, semi-flexible filamentous fd virus. The phase diagram of fd-PNIPAM system becomes independent of ionic strength at high salt concentration and l…
In this paper, the complexities involved in both microbiologically influenced corrosion and deterioration of reinforced concrete structures by algae are explained. In this regards, the five possible corrosion/deterioration mechanisms that may be expected are addressed and described. These mechanisms are as follows: Ab…
In organic light emitting devices (LEDs) various types of emissive states are created: (i) molecular excited states (localized excitons), or bimolecular (B-M) species: excimers, electromers, exciplexes and electroplexes. The consequences of the formation of B-M excited species for optical and electrical characteristic…
Although ultrasound-based drug delivery has only seen limited clinical use for transdermal drug delivery, there has been considerable momentum in research aimed at using ultrasound for a wide variety of medical applications. Ultrasound-mediated gene therapy using sonoporation and targeted delivery has progressed from…
At least 28 proteins have now been defined as collagens (Trends Genet. 20:33-43, 2004; J. Biol. Chem. 281:3494-3504, 2006), but many of those recently discovered are present in tissues in such small amounts that their isolation for characterization at the protein level has so far been impossible. Some of the fibrilfor…
