These refer to unit activities at 900°C and the Ca/Ca 2+ standard, with pure liquid CaO as the reference state for the oxide, and have been calculated from known thermodynamic data.
These issues prompted a second in-depth study on TiO2 reduction [10].
Fig. 5 shows a current versus time curve recorded during a reduction experiment of the above type.
Two cases in point are the preparation of Ti coatings on steel through the reduction of deposited TiO2 [12], and the preparation of highly porous Ti metal through the reduction of TiO2 precursors containing fugitive additives [13].
The main concern is that this parasitic reaction results in a reduction in the current efficiency.

More recently larger blades have been used, where main advantages include an increase in wind capture efficiency, a reduction in the installation and reduction in maintenance costs per MW.
The initial measurement data shows all motion relative to the camera system, where a coordinate system transformation is applied to set the global coordinate system relative to the turbine.
Fig. 14: Tower versus blade deflection during an emergency stop Fig. 15: Vector plots that can be animated during review of captured data show 3D resultant displacements for three similar points on each blade.

Gold nanoparticles with size smaller than 8 nm were immobilized in the silica network and the as-prepared Au NP/m-SiO2 tubes exhibit good catalytic activity towards the reduction of p-nitrophenol.
The gold NPs were synthesized by PLT reduction of gold precursor under alkaline solution, followed by biomimetic silicification mediated by PLL to immobilize gold NPs in the silica network.
SEM and TEM characterization show that the well-defined tubular structure was obtained as well and the materials are porous (data not shown).
Reduction of p-nitrophenol by NaBH4 was widely used to measure the catalytic property of the gold [3, 19-21], silver particles [22] or gold/silica composite [23, 24].
According to literature data, this catalyst-mediated reduction can be assumed as a pseudo-first-order reaction [3, 19-24].

Carbothermal reduction treatment was performed to the reduce oxygen content within the powder during this procedure Heat treatment with tube furnace was performed using 0.1 l/min flow rate nitrogen atmosphere for 10h at 1450℃.
Results and discussions A graded structure was obtained by an additional carbothermal reduction treatment.
Data shows that oxide is more easily formed in fine surface compared to coarse surface.

Each datum point represents the average of at least six readings.
It is observed that the hardness increases with hot rolling reduction ratio.
At lower hot rolling reduction ratio, it is observed that both hardness and impact toughness are increasing with high fluctuation in readings with decreasing hot rolling reduction ratios.
However, impact toughness decreases with increasing reduction ratio.
Reduction Ratio in all alloy samples in Fig. 2(c, d) around ~6%.

Tawakoli et al [7-10] demonstrated that in ultrasonic assisted grinding and dressing, considerable reduction in grinding forces, surface roughness, grinding wheel wear and dresser wear is achievable.
Reduction in the radial wear of the grinding wheel, the grinding forces and improvements of surface roughness due to superimposing of ultrasonic vibration in the grinding of 100Cr6 have been achieved.
In order to achieve reliable data each test was repeated 3 times.
In all figures, lines were formed by calculating the least-squares fit through the data points for a second-order polynomial equation.
• Comparative experiments demonstrated up to significant reduction in radial wear of the grinding wheel and grinding forces for the workpieces machined with superimposed ultrasonic vibration

The simulated free vibration data is compared to those obtained via experiments.
The results are compared to experimental data obtained via knocking tests.
The software FFT module was used to obtain the frequency data from the time domain input.
However there is a large discrepancy in data for the 100 and 120 mm overhang cases.
The simulated frequency data is comparable to the experimental data, for the shorter overhangs of 50 and 70 mm.
