The methodology of ultrafast multiple-mode multiple-dimensional vibrational spectroscopy has been developed and applied to investigate the vibrational energy dissipation in condensed phase. In particular, experiments have been focused on the studies of vibrational energy relaxation and mode-specific vibrational energy…
This work is firstly focused on the synthesis of green, orange-red and red emitting heteroleptic iridium(III) complexes and their application as emitting materials in the area of OLEDs and oxygen sensors. Furthermore, in order to obtain energy transfer from the polymer backbone (host material) to the polymer-incorpora…

The Cu^(2+)-O-Cu^(2+) core in ZSM-5 zeolite is, thus far, the only well-characterized copper intermediate in the methane to methanol reaction. This recent discovery has had a broad impact in the field of heterogeneous catalysis and bioinorg. chem. Next to its identification, its formation pathway both from N_2O and O_…

We investigate the properties of clusters formed from two connected $\mathrm{Ge_{m}}$ cage-like clusters, such as experimentally synthesized $\mathrm{Au_3Ge_{18}^{5-}}$, using first-principles DFT methods. We focus particularly on $\mathrm{Au_nGe_{12}^{q-}}$ formed from $\mathrm{Ge_{6}}$, where $n=0-3$ and $q=0,2$. We…
Prior to European contact, ceramic technology was nonexistent among Native American groups in California north of the Los Angeles basin. Fired clay roof tiles, floor tiles, and water pipes were a necessity for the development of the infrastructure for California's system of missions, presidios, and pueblos. Likewise,…
ABSTRACT: To achieve environmental conservation dyeing, instead of traditional retarding reagent 1227, biodegradable hydroxypropyl-β-cyclodextrin (HP-β-CD) was studied as a dye retardant in the dyeing of polyacrylonitrile fiber with cationic dyes. The results showed that hydroxypropyl-β-cyclodextrin was an effective l…
One way to improve the solubility of a poorly-water-soluble drug is to make amorphous solid dispersion of it with one or several carrier polymers. However, the amorphous solid dispersions are often unstable. Stability and amorphisation of drug substance depend on e.g. the miscibility of the components in dispersion. M…
The purpose of this contribution is to report on preliminary nano-continuum scale modeling of nuclear waste glass corrosion. The focus of the modeling is an experiment involving a French glass SON68 specimen leached for 25 years in a granitic environment (Guittonneau et al., 2011; Gin et al., 2011; Gin et al., 2013).…
Calcium carbonate and titanium dioxide (0.5 g/100g gluten and 1 g /100g gluten) were tested as fillers to observe their effects on different mechanical and barrier properties of biodegradable films made from heated alkaline aqueous solution of wheat gluten, ethanol, and glycerol. Tensile Strength, % Extension and wate…

The title compound, [Eu2(C7H5O2)6(C15H11N3)2(H2O)2]·2C7H6O2, is a co-crystalline compound containing a dinuclear Eu(III) coordination complex with inversion symmetry co-crystallized with benzoic acid in a 1:2 ratio. The Eu(3+) ions within the dimer are nine-coordinate, containing one tridentate terpyridine, one water,…
Metal cynogen complex namely potassium tetracyanonickelate has been synthesized and characterized using magnetic susceptibility, TGA/DTA/ IR, CHN analysis and XRD techniques.Adsorption studies of ribose nucleotides, 5'-AMP, 5'-CMP, 5'-UMP and 5'- GMP were done IR sutdies revealed taht 5'- AMP, 5'- CUMP, 5'-CMP showed…
The magneto-impedance response of narrow multilayered NiFe/Cu/NiFe structures realized by micromolding has been characterized as a function of both the excitation frequency and the magnetic field. It has been found that intrinsic magnetic properties do not depend on the ferromagnetic geometry, but properties related t…
In this work, a low-cost and CMOS-compatible fabrication method to produce CMOS-MEMS porous silicon inetial sensors by using a thick oxidized prous silicon (OPS) layer is demonstrated. The OPS layer was fabricated before the standand CMOS process used for defining the contour of MEMS structures as well as dielectric i…
High quality local Germanium-on-oxide (GeOI) wafers are fabricated using selective lateral germanium (Ge) growth technique by a single wafer reduced pressure chemical vapor deposition system. Mesa structures of 300 nm thick epitaxial silicon (Si) interposed by SiO2 cap and buried oxide are prepared. HCl vapor phase et…
