Inorganic support

Ebook "Challenges in molecular structure determination" provide a practice-oriented and systematic introduction to both organic and inorganic structure determination by spectroscopic methods. This includes mass spectrometry, vibrational spectroscopies, UV/VIS spectroscopy and NMR as well as applying combinations of these methods. The authors show how to elucidate chemical structures with a minimal number of spectroscopic techniques. Readers can train their skills by more than 400 problems with varying degree of sophistication.

Cesium is an inorganic compound, which is not approved by the Food and Drug Administration (FDA), and is available as over-the-counter (OTC) drug. Despite lack of supportive data on efficacy, and evidence of safety of the cesium, this drug is used by the patients for treatment of cancer depression and other conditions.

We describe the synthesis, characterization and catalytic properties of a series of hybrid materials composed of inorganic plasmonic mono- and bimetallic nanoparticles supported on organic bio-based hydrogel beads. The bimetallic materials showed a localized surface plasmon resonance in the visible region, with a maximum light absorption correlated to the metal composition of the alloyed systems.

Soil microorganisms are supportive in the transformation of soil phosphorus (P) and are thus an important component of the soil P cycle. These are effective in releasing P both from inorganic and organic pools of total soil P through their respective solubilizing and also enhance the soil microbial and enzymatic activities.

Inorganic or inorganic-organic hybrid nanomaterials have great potential for applications in the biomedical fields. Biological half-life is an essential pharmacokinetic parameter for these materials to function in vivo. Compared to inductively coupled plasma mass spectrometry (ICP-MS), which is the gold standard, laser-induced breakdown spectroscopy (LIBS) is a faster and more efficient elemental detection method. We investigated an efficient way to quantify the metabolic rate using LIBS.

Volcanic ejecta or lahar can serve as an inorganic support for the immobilization of invertase. Pampanga and Bicol lahar samples were pretreated by ignition at 550o C for 5 hrs followed by concentrated hydrochloric acid treatment, activated by reaction with aminopropyltriethoxysilane (APTS) and then covalently bound to invertase using glutaraldehyde as linker. Chemical tests confirmed the attachment of APTS to lahar and glutaraldehyde to silanized lahar. The quantity of immobilized invertase on Pampanga white, Pampanga black and Bicol black lahar were 98.73%, 96.73% and 84.27%, respectively.

This Investigation was undertaken in the wetlands farm of Tamil Nadu Agricultural University, Coimbatore during Thaladi season to study the ecology of birds and insects in inorganic and organic rice ecosystem, with special reference to the species abundance, diversity, richness, evenness and similarity indices. This study revealed that organic cultivation supports bird diversity and beneficial insects. However, the bird menace during maturity stage is an issue to be managed in an ecofriendly way.

Investigation into the effect of fly ash with three organic manures viz., Farm yard manure (FYM), green leaf manu) and Humic acid (HA) and inorganic fertilizers on the yield and uptake of rice was studied. The test crop was rice variety (ADT 49) Field experiment was conducted during 2014-15 in Krishi Vigyan Kendra, Tirur, Tamil Nadu Agricultural University. Fly ash generated from Mettur Thermal Power Station was selected for the study and examined for its physical and chemical properties. Analysis of fly ash revealed that it is neutral to alkaline (pH 8.1) in reaction.

A series of 1-(1,3,4-thiadiazolo)-2-thioxo-pyrimidines 4a-g are synthesized by the condensation of monosubsituted thioureas la-g, ethyl acetoacetate 2 and aryl aldehyde 3 in dry media using microwave irradiation. The reactions are completed in very short time with high yield. The use of inorganic solid supports has been proved as an alternative mean of synthetic media.

An ecosystem is a biotic (organic) community joined with the abiotic (inorganic) conditions it lives in. Abiotic factors determine the kind of biotic community that will be found in a given area because the biotic community is both supported by and limited by the abiotic factors. Ecosystems are important because they are the functional units of sustainable life on Earth, making them models of the cycles that produce sustainability.

Potassium permanganate absorbed on copper(II) sulfate pentahydrate oxidizes aniline into azobenzene under heterogenous conditions. Azoxybenzene is a minor by-product. Under solventless reaction conditions, the oxidation does not take place owing to predominant complex formation between copper(II) and aniline. The influence of the nature of the solvent as well as the replacement of copper(II) sulfate pentahydrate by several other inorganic salt hydrates on the potassium permanganate promoted oxidation of aniline is described.

The nano-scale spatial organization of metallic and other inorganic materi-als into 1D objects is a key task in nanotechnology. Nano-scale fibers and tubes are very useful templates for such organization because of their inherent 1D organization. Fibrillar biological molecules and biomolecular assemblies are excellent physical supports on which to organize the inor-ganic material.

Bone is the major constituent of the skeleton which is a hallmark of all higher vertebrates. Besides the protection of internal organs and the support of body structures, the most important functions of bone are to serve as an attachment site for muscles allowing locomotion and provide a cavity for hematopoiesis in the bone marrow (Mendez-Ferrer et al. 2010; Zaidi 2007). Moreover, bone has a central role in mineral homeostasis as it functions as a reservoir for inorganic ions that can be mobilized rapidly on metabolic demand...
