Interactions of nanoparticles with biological matter-both somatically and in nature-draw scientists' attention. Nanoparticulate systems are believed to be our saviors, acting as versatile drug delivery vehicles. However, they can also cause life-threatening bodily damage. One of the most important properties of nanocrystalline cerium dioxide is its antioxidant activity, which decreases the abun...
The target of this paper is to draw a comparison between information in living systems and information in inorganic contexts. The two representative contexts we will refer to are those of an organism and of solid state physics. We have published extensively elsewhere on the properties of a model hierarchy (e.g. Cottam et al, 2003; and most recently Cottam et al, 2016; Cottam et al, 2017), and t...
The studies in the Chair of Inorganic Chemistry of the Institute Chemistry of the University of Tartu (ICUT) in period (20072012) have been directed by both getting new fundamental knowledge in inorganic chemistry and application the knowledge in solution of different practical problems of society. Traditionally the main study area of the Chair has been conductive polymers, more exactly electro...
1. All inorganic perfusing solution for the heart of the lobster Homarus americanus, to allow prolonged normal beating (20 hours or more) must agree closely with the inorganic composition of the serum, which varies differentially with that of the environmental sea water. 2. All of the chief inorganic ions of the serum are necessary-Na, K, Ca, Mg, Cl, and SO(4); the critical numbers of the ions ...
The concept of using a thermoresponsive ionic liquid (IL) with an upper critical solution temperature (UCST) as a draw solute in forward osmosis (FO) was successfully demonstrated here experimentally. A 3.2 M solution of protonated betaine bis(trifluoromethylsulfonyl)imide ([Hbet][Tf2N]) was obtained by heating and maintaining the temperature above 56 °C. This solution successfully drew water f...
The synthesis of a high-melting temperature semiconductor in a low-temperature fiber drawing process is demonstrated, substantially expanding the set of materials that can be incorporated into fibers. Reagents in the solid state are arranged in proximate domains within a fiber preform. The preform is fluidized at elevated temperatures and drawn into fiber, reducing the lateral dimensions and br...
bone like hydroxyapatite (nhap) was synthesized via an in situ biomimetic process in presence of wheat starch. the effect of polymer concentration alteration on the final structure of nhap was investigated. formation of the nhap at room temperature was confirmed by x-ray diffraction (xrd) and fourier transform infrared spectroscopy (ft-ir). size and morphology of the nhap samples were character...
Seawater desalination plants discharge brine which is at higher salt concentration than the supplied seawater feed. Diluting this brine by mixing it with the lower concentration feed (seawater) will reduce the environmental hazards associated with the high salt concentration of the disposed brine. Energy can be generated from the dilution process in which two streams of different salt concentra...
There is a long-standing challenge to realize in situ visualization of incorporated inorganic materials in organic–inorganic composites in a post-labeling manner, owing to the lack of specific fluorescent organic dye molecules for targeting inorganic materials. Herein, we observe that the specific covalent B–O binding between the hydroxyl groups of inorganic materials and commercially available...
desulphurization of coal by using of thiobacillus ferrooxidans and thiobacillus thiooxidans bacteria
a new solution aiming at coal biodesulphurization has been developed based on the use of bacteria. the most frequently used species of bacteria for removal of inorganic sulphur compounds are thiobacillus ferrooxidans, thiobacillus thiooxidans and thiobacillus acidophilus. in this study the coal sample was decomposed initially and desulphurization experiments was carried out in pure and mixed cu...
