On the basis of 1H and 13C NMR spectroscopy studies, the proportion of pyranose and furanose forms of 6-deoxyheptoses in water solution was determined. Water solution of 6-deoxyheptoses contains all possible furanose and pyranose forms (except 6-deoxy-gluco-heptose for which only pyranose was found), although pyranose is dominant.

The retention of zirconia-based ceramic posts (CosmoPost system) luted with glass ionomer and resin cements was evaluated. Thirty-two extracted, caries-free, unrestored teeth were selected and stored in chlorhexidine and water solution. The teeth were endodontically treated and randomly assigned to two groups (n=16). Each tooth was decoronated and prepared to a depth of 10.0 mm from root surfac...

This paper describes microfluidic channels that can be erased and then reconstructed. These channels were constructed between two stacked lass slides. These slides had ground and hydrophobic surfaces, and a line had previously been drawn on their surfaces using an inkjet printer ith a water-soluble liquid as its “ink”. A water solution was injected between the slides, and it flowed along the pr...

The characteristics of inorganic particles generated in glass vials filled with phosphate buffer solutions were investigated. During storage, particles were visually detected in the phosphate buffer solution in particular glass vials which pass compendial tests of containers for injectable drugs. These particles were considered to be different from ordinal glass delamination, which has been rep...

Rosamine derivative RC-1, bearing macrocyclic ligand [15]aneNO(2)S(2) as receptor, was synthesized as an enhanced fluorescent chemosensor for Ag(+) in absolute aqueous solution. The fluorescence images in living cells show the potential application of RC-1. The difference of fluorescence enhancement process after binding with Ag(+)/Hg(2+) in acetonitrile/water solution was first proved by theor...

Splash is the first stage of a negative phenomenon-soil erosion. The aim of this work was to describe the crown formation quantitatively (as part of the splash erosion) and compare the course of this phenomenon on the thin water film formed on a smooth glass surface and on the surface of saturated soil. The height of the falling water drop was 1.5 m. The observation of the crowns was carried ou...

Visible-light-responsive tubular N-doped TiO2 nanocrystallites were synthesized via an environment-conscious solvothermal treatment of protonated titanate nanotubes in an NH4Cl/ethanol/water solution.

Nano Bioactive glass material of the type CaO–P2O5–SiO2 was obtained by the sol-gel processing method at considerably lower temperatures than required for conventional melting methods. As a new modification, volume of solution was changed in order to investigate its effects on the properties of bioglass samples. The obtained material was characterized by X-ray powder diffraction (XRD), surface ...
