In order to develop a suitable green phosphor for plasma display panels (PDPs), samples Ca 5 − 2 x Tb x Na x ( P O 4 ) 3 F for x = 0.20 , 0.35, 0.50, 0.65, 0.80, and 0.95 were prepared by a solid-state reaction technique at high temperature. The vacuum ultraviolet (VUV, wavelength λ < 200 nm and the energy E 50 , 000…
Macroporous styrene-divinylbenzene (St-DVB) co-polymer microspheres can be synthesized through the free-radical cross-linking co-polymerization of styrene and divinylbenzene in the presence of an inert diluent. The research developments such as in preparation methods, synthesis variables and various applications achie…
The study of conformational transitions of peptides has obtained considerable attention recently because of their importance as a molecular key event in a variety of degenerative diseases. However, the study of peptide self-assembly into beta-sheets and amyloid beta (Abeta) fibrils is strongly hampered by their diffic…
Liposome Technology, Second Edition, is an updated, expanded new edition of a classic volume in the field. It covers all aspects of liposome technology, including liposome preparation and analysis, drug entrapment, and techniques used for in vivo and in vitro evaluation of liposomes. Leading authorities have contribut…
It was observed experimentally that a chemical reaction limiting current can be affected by flow. In the present study a new more general expression than the one found in literature was derived for the superposition of the diffusion and chemical reaction controlled limiting currents . It was found that their interacti…
Electromagnetic scattering of metallic column covered by double-negative (DNG) metamaterials is simulated with auxiliary differential equation method in Finite-Difference Time-Domain method. Lossy Drude polarization and magnetization models are used to simulate DNG media. Numerical result shows that though the backwar…
Calcination of lysozyme-silica hybrid hollow particles gives novel cage-like hollow spherical silicas with differently patterned through-holes on their shell structure.
We report the one pot synthesis of a silver-polymer nanocomposite in supercritical carbon dioxide (scCO(2)) whereby an organometallic silver complex is thermally decomposed in the presence of a reversible addition fragmentation chain transfer (RAFT) agent during a polymerisation reaction in which the RAFT agent simult…
The complexes [Et(4)N](3)[Ln(eta(2)-dcnm)(6)] (Ln = La, Ce, Nd, Gd, dcnm = dicyanonitrosomethanide) have discrete N, O 12-coordination owing to symmetrical chelation of the nitroso donor groups.
The celebrated physicist and Nobel laureate Richard Feynman was the first to predict the opportunities presented by the manipulation of matter at the level of individual atoms and molecules. Today, almost 50 years after his classic lecture on the wonders of the small world, the evolving nanotechnologies have the poten…
A series of C2-symmetric bridged silsesquioxanes derived from L- and D-valine have been designed and synthesized. They were capable of forming physical gels in organic solvents such as ethanol, THF, and 1,4-dioxane. These silsesquioxanes formed helical bundles in 1,4-dioxane. With respect to the helical sense, a clear…
Emissive terbium complexes, suitable for protein conjugation, incorporating a pyrazoyl-1-aza-xanthone chromophore have been prepared; they exhibit cellular uptake and possess a much lower sensitivity to excited state quenching.
Metal and semimetal nanotube-nanowire heterojunction arrays have been achieved by sequential electrochemical-deposition inside the nanochannels of anodic aluminium oxide template with a layer of Au thin enough to leave the pores open.
The synthesis, photophysical and photochemical properties of the tetra- and octa-poly(oxyethylene)substituted zinc (II) phthalocyanines are reported for the first time. The new compounds have been characterized by elemental analysis, IR, 1H and 13C NMR spectroscopy, electronic spectroscopy and mass spectra. General tr…
In this paper, we review the recent development of synthetic architecture of nanomaterials through oriented aggregations of primary colloidal particles. Various organising manners via this mechanism have been illustrated, and the relationships among zero-, one-, two-, and three-dimensional (0D, 1D, 2D and 3D) material…
A novel, thermally curable, tri-component organic glass for electro-optic applications was designed and synthesized. The system employed the Diels–Alder cycloaddition reaction to effect efficient cross-linking. The first component was a dendrimer containing multiple electro-optic chromophore substituents surrounded by…
The reaction of 2 equivalents of 2-methyl-1,4-bis(2,6-dimethylphenyl)-1,4-diaza-1,3-butadiene, ((1)L(Ox))(0), or 2-methyl-1,4-bis(2,6-diisopropylphenyl)-1,4-diaza-1,3-butadiene, ((2)L(Ox))(0), in diethyl ether or n-hexane with 1 equivalent of Ni(cdt) where (cdt)(0) is the ligand cyclododecatriene affords dark red, dia…
We have studied the effect of thermal evaporation rate on the basic physical properties of glassy (As2S3) x (As2Se3)1−x thin films on glass substrates and have determined the optimal range of deposition rates corresponding to the highest photosensitivity and long-term stability of the films. The results are interprete…
Mechanochemical synthesis of zinc ferrite, ZnFe2O4, was attempted from a powder mixture of iron (III) oxide, alpha-Fe2O3 and zinc (II) oxide, ZnO. Nanocrystalline zinc ferrite, ZnFe2O4 powders were successfully synthesized only by milling for 30 hours. The X-ray diffraction spectrum of the as-milled powders (without h…
We propose and optimize the antireflection coating composed of a row of tapered dielectric waveguides for two-dimensional air hole-type photonic crystal negative refraction slab lens. The image quality of the lens with the antireflection coating is improved. The simulation result using finite difference time domain me…
