AIM To evaluate the effect of different mouth rinses 12 h after rinsing on genuine intra-oral halitosis. MATERIALS AND METHODS Twenty-four adults with halitosis were included in a double-blind, crossover, randomized clinical trial. Halitosis was evaluated 12 h after rinsing with placebo and five mouth rinse products containing zinc acetate and chlorhexidine diacetate; zinc lactate, chlorhexid...

Graphene, a monolayer of graphite, has appeared as one of the most fascinating materials of today’s Material Science research. The properties of graphene (GR) with high electronic conductivity, extraordinary strength and interesting chemical characteristics make it suitable for many different applications. All these tremendous properties of GR are relevant at the nanoscale, hence, in a view to ...

Langmuir–Blodgett (LB) technique has been used to deposit composite multilayers of poly(3-octylthiophene) with cadmium arachidate (POT-CdA), zinc arachidate (POT-ZnA) and copper arachidate (POT-CuA). These composite multilayers were used as precursors to develop the respective semiconducting CdS, ZnS and Cu2S nanoclusters in the POT-arachidic acid (POT-AA) matrix. The formation of sulphide nano...

An investigation was undertaken in relation to the contamination of a facility used for the servicing and refurbishment of gaseous tritium light devices. While it is generally accepted that there is minimal exposure hazard from a broken gaseous tritium light source after the tritium gas has dispersed, environmental tritium contamination displaying ‘particulate’ like characteristics was observed...

Zinc sulphide thin films have been deposited with CADT using zinc chloride and zinc acetylacetonate as Zn compounds and thiourea and 1,1,3,3-tetramethylthiourea as S compounds soluted in methanol, ethanol, isopropanol and cellosolve. After optimalization of the deposition process homogeneous layers with a c-axis oriented hexagonal columnar structure with a high density (up to 96%) were obtained...

The lead-zinc-barium deposits of the southern Benue Trough, Nigeria belong to a suite clastic dominated fracture filling hydrothermal vein deposits. alteration types and spread are poorly known yet required aid exploration. Band ratio composites (BRC), Principal Component Analysis (PCA), Minimum Noise Fraction (MNF) were applied full scene Advanced Spaceborne Thermal Emission Reflection Radiome...
