An innovative route is reported to fabricate nano-particles in aqueous solution from oxyfluoride glass by the thermal induction and corrosion treatment in this letter. The investigations of X-ray diffraction and transmission electron microscope based on nano-particles in glass ceramics (GCs) and aqueous solution indicate that the nano-particles formed in glass matrix during the thermal inductio...

Some microscope slide mountants exhibit a tendency to spread beyond the periphery of their cover slips, flowing over the edge and under the slide, fouling the stationary and moving components of the mechanical stage. In the authors' experience, mountants that are most commonly associated with this problem are alcohol, lactophenol, water and other water-soluble preparations of low viscosity. The...

Mud formed from environmental dust particles in humid ambient air significantly influences the performance of solar harvesting devices. This study examines the characterization of environmental dust particles and the chemo-mechanics of dry mud formed from dust particles. Analytical tools, including scanning electron microscopy, atomic force microscopy, energy dispersive spectroscopy, particle s...

to investigate and compare the amount of fluoride release of conventional, resin modified and nanofilled resin modified glass ionomer cements.tablets of glass-ionomer cements were immersed in deionized water and incubated at 37°c. after 1, 2, 7, 15 and 30 days, fluoride ion was measured under normal atmospheric conditions by fluoride ion selective electrode. buffer (tisab ii) was used to decomp...

Grinded glass fiber (GGF) embedded high density polyethylene (HDPE) membranes were prepared via thermally induced phase separation method. FESEM images showed that all the membranes had leafy structure, indicating a solid-liquid mechanism during phase separation. The results of EDX and TGA analyses confirmed that the fibers were dispersed in the HDPE matrix uniformly. Normalized water flux of t...

We studied the dynamics of dissolved water in aluminosilicate glasses with the compositions NaAlSi3O8·0.3H2O, NaAlSi3O8·1.3H2O and Ca0.5AlSi3O8·1.3H2O using quasielastic neutron scattering. As shown by near-infrared spectroscopy on these samples, H2O molecules are the predominant hydrous species in the water-rich glasses whereas OH groups bound to tetrahedrally coordinated cations are predomina...

BSA solutions of 10 %, 1 % and 0.1 % were prepared by addition of lyophilized BSA powder (Sigma Aldrich, St Louis, MO, USA) into deionized water before being filtered through a glass fiber filter (Whatman GF/F) under vacuum in order to remove particles that can clog the system. Tween 80 was then added to a obtain 0.05 % [V/V] solution. The BSA solutions were then refrigerated before use. All so...

abstract background: the aim of this study was to compare the efficiency of conventional slow sand filter with modified filter bed with crushed recycled glass in removing of turbidity and total and fecal coliforms from water resources.   methods: in this study efficiency of conventional slow sand filter and modified filter bed with crushed recycled glass during 4 months was compared and their p...
