For example, if Coating A has a contrast ratio of 0.920 and Coating B has a contrast ratio of 0.900, about all that can be said is Coating A has higher opacity than Coating B. We can say it is 0.020 higher, but it is not clear how to use this number to formulate Coating B to have equal hiding. Also, this is not helpful in deciding what to change in order to improve opacity. Fortunately, quantit...

A new optical fiber and method of manufacturing the same developed for use with surgical laser systems. The fiber core utilizes an ultra-low expansion (ULE) material. The preferred ULE fiber consists of silicon dioxide core doped with titanium dioxide which is cladded and jacketed for chemical and abrasion resistance. The resulting fiber is stable against degradation due to thermal expansion.

Today, the use of natural polymers and their replacement with synthetic polymers in various fields of science has attracted much attention. Reducing the associated risks, easy access, and being cost-effective are among the advantages of using natural polymers compared to the synthetic polymers. In this research, the destruction of amylopectin in the presence and absence of titanium dioxide nano...

The immobilization of titanium dioxide is necessary for several energy and environmental applications such as dye-sensitized solar cells (DSSCs). A two-step fabrication route has been developed in this work including a near room temperature hydrolysis reaction to produce immobilized (NH4)2TiOF4 arrays, followed by successive topotactic transformations immobilised TiO2 mesocrystals (imcTiO2). Hi...

The Minnesota Nano Center’s Keller Hall facility includes an atomic layer deposition (ALD) machine that is capable of depositing uniform alumina (Al2O3), hafnium oxide (HfO2), silicon dioxide (SiO2), zinc oxide (ZnO), and titanium dioxide (TiO2). ALD works by building alternate layers on a film using two different precursor gases – one usually supplying the metallic atoms and water vapor (H2O) ...

an investigation was initiated to examine the effects of nanoscale titanium dioxide particles on plant growth and development. in view of the widespread cultivation of canola in iran and in other parts of the globe and in view of the potential influence of titanium on its growth, this plant was chosen as the model system. canola seeds were separately treated with different concentrations of nan...
