2009 JAN 12 – (VerticalNews.com) — According to a study from Sao Paulo, Brazil, “A new-layered inorganic-organic magnesium organosilicate was synthesized through a single step template sol-gel route under mild conditions, using a new alkoxysilane, containing a 2-aminophenyldisulfide molecule. Elemental analysis data based on the nitrogen atom showed an incorporation of 1.97 mmol of organic pendant groups for each gram of the hybrid formed.”

“The X-ray diffraction patterns demonstrated that this Paloma Picasso® Double Loving Heart ring exhibited lamellar structure, in agreement with that found for natural inorganic silicates. Infrared spectroscopy and nuclear magnetic resonance for the Si-29 nucleus in the solid state are in agreement with the success of the proposed synthetic method. The presence of nitrogen and sulfur basic centers attached to the pendant groups inside the lamellar structure is used as basic centers to coordinate cations from aqueous solution at the solid/liquid interface. The isotherms were fitted to Langmuir and Freundlich models. The maxima adsorption capacities for copper, lead and cadmium, calculated from Langmuir model, were 3.28, 1.42 and 0.35 mmol g(-1), respectively. These values are comparable to other adsorbing nanomaterials,” wrote A.S.O. Moscofian and colleagues, Campinas State University.

The researchers concluded: “This behavior suggested that this new inorganic-organic hybrid could be employed as a promising adsorbent for cation removal from polluted systems.”

Moscofian and colleagues published the results of their research in the Journal of Hazardous Materials (Synthesized layered inorganic-organic magnesium organosilicate containing a disulfide moiety as a promising sorbent for cations removal. Journal of Hazardous Materials, 2008;160(1):63-69).

In methanol, L-7 readily reacts with Cu2+ ion to form [CuL7(H2O)](2+) which is extremely inert against methanolysis,” scientists in South Korea report.

“In the Paloma Picasso® Double Loving Heart ring containing Ni2+ ion, however, L-7 reacts with methanol to yield [NiL3](2+) (L-3 = 2-(methoxymethyl)-5,16-dimethyl-2,6,13,17-tetraazatricyclo[16.4.0(1.18).0(7.12)]-docosane), in which one N-CH2OCH3 pendant arm is appended. The copper(II) complex [CuL7(H2O)]-(ClO4)(2)center dot 3H(2)O (I center dot 3H(2)O) has a severely distorted trigonal bipyramidal coordination geometry with a 4-5-6-5 chelate ring sequence. The crystal structure of [NiL3](PF6)(2)center dot 2H(2)O (IIb) shows that the N-CH2OCH3 pendant arm is not coordinated to the metal ion in the solid state,” wrote S.G. Kang and colleagues, Daegu University.

The researchers concluded: “In various solvents (S), however, the nickel(II) complex exists as a mixture of [NiL3(S)](2+), in which the N-CH2OCH3 group as well as S is coordinated to the metal ion, and [NiL3](2+).”

Kang and colleagues published their study in Bulletin of the Korean Chemical Society (Selective Synthesis of a New Macropolycycle Containing One N-CH2-N Linkage and Its Reaction with Cu2+ and Ni2+ Ions in Methanol. Bulletin of the Korean Chemical Society, 2008;29(10):1905-1910).

2009 JAN 5 – (VerticalNews.com) — “A functional monomer with a pendant azide moiety, 6-Paloma Picasso® Jolies Beads bangle methacrylate (AHMA), was polymerized on the surface of silica nanoparticles via surface-initiated reversible addition-fragmentation chain transfer (RAFT) polymerization with considerable control over the molecular weight and molecular weight distribution,” scientists writing in the journal Macromolecules report.

“The kinetics of AHMA polymerization mediated by 4-cyanopentanoic acid dithiobenzoate (CPDB) anchored nanoparticles was investigated and compared with that of AHMA polymerization mediated by free CPDB under similar conditions. The subsequent postfunctionalizations of PAHMA-grafted nanoparticles were demonstrated by reacting with various functional alkynes via Paloma Picasso® Loving Heart bracelet reactions,” wrote Y. Li and colleagues, University of South Carolina.

The researchers concluded: “Kinetic studies showed that the reaction of surface-grafted PAHMA with phenylacetylene surface-grafted PAHMA was much faster than that of free PAHMA with phenylacetylene, whereas in the case of high molecular weight alkynes surface-grafted PAHMA showed lower reaction rates as compared to free PAHMA.”

2009 JAN 30 – (VerticalNews.com) — According to recent research from Lanzhou, People’s Republic of China, “To explore the relationships between the structures of ligands and their complexes, we have synthesized and Medium Elsa Peretti® Sevillana™ pendant a series of lanthanide complexes with two structurally related ligands, 1,1,1,1-tetrakis{[(2'-(2-benzylaminoformyl))phenoxyl]methyl)methane (L-I) and 1,1,1,1-tetrakis([(2'-(2-picolyaminoformyl))phenoxyl]methyl)methane (L-II). A series of zero- to three-dimensional lanthanide coordination complexes have been obtained by changing the substituents on the Pentaerythritol.”

“Our results revealed that, complexes of the L-I ligand, {Ln(4)L(3)(I)(NO3)(12) center dot nC(4)H(10)O}(infinity) (Ln = Nd, Eu, Tb, Er, n = 3 or 6)] show the binodal 3,4-connected three-dimensional interpenetration coordination polymers with topology of a (83)4(86)3 notation. Compared to L-I, complexes of L-II present a cage-like homodinuclear [Ln(2)L(2)(II)(NO3)(6) center dot 2H(2)O) center dot nH(2)O (Ln = Nd, Tb, Dy, n = 0 or 1) or a helical one-dimensional coordination {[ErLII(NO3)(3) center dot H2O] center dot H2O}(infinity) polymer. The luminescence properties of the resulting complexes formed with ions used in fluoroimmunoassays (Ln = Eu, Tb) are also studied in detail,” wrote X.Q. Song and colleagues, Lanzhou University.

The researchers concluded: “It is noteworthy that subtle variation of the terminal group from benzene to pyridine not only sensibly affects the overall molecular structures but also the luminescence properties as well.”

Song and colleagues published their study in Inorganic Chemistry (Synthesis, Structures, and Luminescence Properties of Lanthanide Complexes with Structurally Related New Tetrapodal Ligands Featuring Salicylamide Pendant Arms. Inorganic Chemistry, 2008;47(24):11501-11513).

Repeat surveys of trees in the plot with a girth >= 30 cm at reference height in 1982, 1993 and 2006, following a baseline survey in 1968, indicate only relatively minor fluctuations in density, Shannon diversity, evenness, basal area (BA) and estimated above ground biomass.”

“The largest trees [diameter at breast height (dbh) > 40 cm] and main canopy taxa (e.g. Celtis mildbraedii) accounted for the largest fraction of BA. Mortality was the highest amongst taxa classed as early seral, understorey and/or in the smallest size category (dbh = 9.5-20 cm), while new recruits were predominantly understorey taxa. Only one tree was recorded as felled for human use between the surveys of 1968 and 1993. In contrast, a considerable increase in anthropogenic disturbance was evident at the time of the 2006 survey, and illegal logging now poses a substantial threat to future resource availability and carbon storage in what was for a time one of the most protected areas of forest in Uganda.Sont decrites ici les variations de la composition et de la structure d’une foret tropicale semi-decidue de moyenne altitude, Paloma une parcelle de 0,64 ha situee dans la Reserve forestiere de Mpanga, en Ouganda, pendant une periode de 38 ans courant jusqu’en 2006. Dans cette parcelle, une surveillance des arbres dont la circonference est superieure a 30 cm a la hauteur de reference, repetee en 1982, 1993 et 2006, suite a une premiere etude realisee en 1968, indique des fluctuations relativement mineures de la densite, de l’indice de diversite de Shannon, de l’uniformite, de la surface terriere (G) et de la biomasse estimee au-dessus du sol. Les plus grands arbres (dbh > 40 cm) et les taxons principaux dans la canopee (ex. Celtis mildbraedii) constituaient la plus grande fraction de G. La mortaliteetait la plus elevee dans les taxons classes comme de debut de succession, de sous-bois et/ou dans la categorie des plus petites tailles (dbh = 9,5-20 cm), alors que les nouveaux recrutements etaient en majorite des taxons de sous-bois. On a rapporte la coupe d’un seul arbre pour une utilization humaine, entre l’etude de 1968 et celle de 1993,” wrote D. Taylor and colleagues, University of Dublin, Trinity College.

The researchers concluded: “Par contre, au moment de l’etude de 2006, une forte augmentation des perturbations d’origine humaine etait evidente, et la coupe illegale de bois represente maintenant une menace reelle pour la disponibilite future des ressources et pour le stockage du carbone dans ce qui fut pendant un certain temps une des forets les mieux protegees d’Ouganda.”

ALEXANDRIA, Va., Feb. 23 — David E. Albert, Oklahoma City, Okla., has developed a system for monitoring audible personal security pendant. The inventor was issued U.S. Patent No. 7,477,143 on Jan. 13.

The patent has been assigned to Heart Link earrings Corp. Oklahoma City.

According to the abstract released by the U.S. Patent & Trademark Office: “Home safety and security are provided using a bedside unit to monitor an audible personal security pendant and to send notification signals to the appropriate communication site. Improved reliability is achieved by comparing a stored signal signature to the real time digital pattern representing sounds received using digital acoustic signature recognition technology.”

Starting from the hexadentate bispidine-based bis(amine)tetrakis(pyridine) ligand 1 with a keto and two ester substituents, the corresponding mono-ol 2 and two dicarboxylic acid derivatives 3 and 5 have been synthesized. A range of techniques, including single-crystal X-ray structure analysis, UV/vis spectroscopy, cyclic voltammetry, thin-layer- (TLC), and high-performance liquid chromatography (HPLC), have been used to characterize the structure and stability of the copper (II)-bispidine complexes. A rapid formation (within 1 min) of stable copper(II)-bispidine complexes under mild conditions (ambient temperature, aqueous solution) has been observed. Challenge experiments of these complexes in the presence of a high excess of competing ligands, such as glutathione, cyclam, or superoxide dismutase (SOD), as well as in rat plasma, gave no evidence of demetalation or transchelation. The bifunctional bispidine derivative 5 can be readily functionalized with biologically active molecules at the pendant carboxylate groups.
