Effects of Nano

2012/10/10To make predictions about the possible effects of nanomaterials across environments and taxa, toxicity testing must incorporate not only a variety of organisms and endpoints, but also an understanding of the mechanisms that underlie nanoparticle toxicity. Here, we report the results of a laboratory experiment in which we examined how titanium dioxide nanoparticles impact the

Effects of Catalyst and Solvent on PbTiO3 Fibers Prepared

Sol-gel processing was used to prepare lead titanate fibers. Titanium isopropoxide and lead acetate trihydrate were used as starting materials and triethanolamine (TEA) was added to form stabilized Pb-Ti complex alkoxide. Effects of catalyst and solvent on the state of precursor solutions, gelation reaction, fiber spinnability, pyrolysis and crystallization were investigated.

Impact of Titanium in Controlling Silver Particle Size on

The addition of titanium to HMS obviously results in a slight decrease of Ag average particle size to 23.0 nm as shown in Figures 4b and S11a, especially for the Ag/Ti-HMS 40 sample. By increasing the Ti content, from a Si/Ti molar ratio of 40–10, a further decrease in Ag particle size is noticed.

New Developments in Nb3Sn PIT Strand: The Effects of

The addition of titanium to bronze-processed Nb/sub 3/Sn wires is known to increase the upper critical field and, thus, improve the high field performance. High resolution studies were done to determine the effect, if any, on the microstructure caused by Ti addition.

Hazardous Effects of Titanium Dioxide Nanoparticles in

Among the NPs, titanium dioxide NPs (TiO 2 NPs) are one of the most highly manufactured and widely used in the world [].TiO 2 is a well-known semiconductor and a versatile compound that exists in three crystalline forms, anatase, rutile, and brookite [14, 21], which can only be activated with UV light due to its high band gap energy (3.0 eV for rutile phase and 3.2 eV for anatase phase).

Frontiers

Titanium (Ti) is considered a beneficial element for plant growth. Ti applied via roots or leaves at low concentrations has been documented to improve crop performance through stimulating the activity of certain enzymes, enhancing chlorophyll content and photosynthesis, promoting nutrient uptake, strengthening stress tolerance, and improving crop yield and quality.

Materials Selection of Optimized Titanium Alloys for Aircraft Applications

select titanium alloys for structural aircraft applications using Ashby's approach. The paper is divided into two parts. An initial section is devoted to describing the different types of titanium alloys used in the aircraft industry. This section will serve as a basis for

Effects of titanium addition and section size on

On the other hand, increasing the casting size essentially lowers the cooling rate that opposes the chilling tendency of titanium. This research was to study the combined effects of titanium and section size on their promotion of compacted graphite (CG) formation, and at the same time how matrix constituents were altered in heavy-wall castings.

Size effects on material yield

The effects of specimen size, Hall–Petch (H-P) grain or subgrain size, particle size plus spacing, and crack size on the yield strength, plastic deformation, and fracturing properties of crystalline materials are described on a dislocation mechanics basis. The size

Effect of Boron and Titanium Addition on the Hot

Abstract The effect of boron and titanium addition on the hot ductility of Nb-containing steel was investigated using hot tensile tests. The fracture surface and the quenched longitudinal microstructure were examined by optical microscopy (OM), scanning electron microscopy (SEM) and transmission electron microscopy (TEM). The results showed that both steel samples had the similar change from
