The reduction in viscosity was observed even at low shear rates, which indicates the absence of extensive spatial structure in the oil heterogeneous system.
Addition of water-based CNT suspensions to water-oil emulsion provide reduction in viscosity only at sufficiently high concentrations of CNT (0.82 wt.%) [10].
The graph shows that the reduction of the dynamic viscosity of the samples is 12-15%.
The reduction in viscosity was observed even at low shear rates, which indicates the absence of extensive spatial structure in the oil heterogeneous system.

Pure nickel (99.999%) was cold rolled by a 95% total reduction, and then samples were annealed at 200 °C for 1 hour and quenched for fully recovery, and finally annealed at 600 °C for 1 hour and quenched in water.
Nickel was cold rolled by a 95% total reduction in thickness and subsequently annealed.
Fig. 1 Hardness data for Ni cold-rolled to 95% after annealing at different temperatures for 1 hour Figure 1 shows the micro-hardness changes of pure nickel annealed at various temperatures, ranging from 100 °C to 800 °C.
After 95% rolling reduction, the microstructure of a cold-rolled nickel showed a typical deformed structure, the micro-texture of this material presented a typical copper-type texture (Fig. 2a), and it was easy to develop strong cube texture after annealing.
Compared with sample A, sample B had more low-angle grain boundaries (see Fig. 5), but less Σ3 grain boundaries (see Fig. 6, sample A is 29.7% and sample B is 12.1%), the sharp reduction of Σ3 grain boundary fractions can significantly low the groove depth of the substrates during high-temperature annealing process.

And in recent years, along with the trends of a global energy saving and carbon reduction, the concept of producing green products with low-carbon, water saving, energy abating, pollution decreasing attributes has arisen.
The printing process is the textile printing via digital data processing through the scanners and digital imaging machines etc to input devices.
The samples adopt the color blocks drawn by the three primary colors and match with four different inks to print respectively on the fabrics in cotton, silk and polyester fiber, and then analyze data after being measured by spectrophotometer. 4.1 Comparison between nano ink and reactive ink digital printing applied to cotton fabrics Apply nano ink and reactive ink digital printing to cotton fabrics.
Collect pictures of theme image and transform them into design sketches, fabrics, data search, analysis, and then confirm the design.
Therefore, this study, primarily through the Nanotechnology with green environmental protection and reduction of carbon from Mimaki Engineering Co.

The magnetic α-Fe nanoparticles were carried out using two-preparation methods that include solution phase metal salt reduction and organometallic precursor decomposition.
In this respect, the well-known reduction methods [6] display limitations due to their lack of variability.
Reduction of transition metal salts is the oldest, easiest and still a widely used method for the preparation of metal nanoparticles.
The crystal size determined by Debye-Scherre equation with XRD data are 15 nm and 45 nm, which are close to the particle sizes calculated from TEM images (12.5 nm and 40 nm for Fig.2.

At a power input of 6.0W, reductions in the evaporator wall temperature of about 32.3℃ and 24.4℃ were obtained for the micro-PHP at vertical and horizontal orientations, respectively.
Fabrication of a silicon-based micro pulsating heat pipe Experiments Fig. 3 illustrates the experimental system, which was composed of the test section, heating unit, data acquisition system, water cold bath, and a video recording system.
The output signals from the thermocouples were collected through a computerized data acquisition system.
As a result of these reductions, significant improvement in the silicon wafer’s reliability may be possible.
The maximum temperature reductions of the evaporator wall between the empty and FC-72 charged micro-PHP were presented.

The inserted steel tubes in the middle of the column cause the reduction of its capacity and the reduction factor from axial loading is bigger than that from bias load.
All data is collected with static strain testing system consecutively.
Generally, compare to bias load, uniaxial compression shows more impact on the value of reduction factor.
With the increase of the eccentricity, the value of the reduction factor decreases.
Thus the reduction caused by the welding should be considered seriously as the tubes in practical projects are all welded.

The oxide thickness was estimated from capacitance-voltage (C-V) data and a profile meter.
This is revealed from C-V data and thermally stimulated current measurements (TSC) on n-type reference capacitors.

This reduction in mechanical performance must be considered during product design to ensure long-term structure endurance.
The reduction in mechanical properties is often due to degradation at matrix/fiber interface [7,8].
The experimental data was used to carry out the coupled mechanical-diffusion analysis. 2D and 3D models were developed in Abaqus to simulate moisture diffusion from any surface and varying moisture/ temperature conditions.
Similarly for 3D model absorption behaviour is shown in Figure 3, which is in close agreement with simulation results and with the experimental data.
Figure 2 Comparison of 2D Abaqus model with Experimental data having absorption for 112 days Figure 3 Comparison of 2D and 3D Abaqus model with In Figure 4 2D moisture diffusion across depth of specimen is deliberately calculated and shown to compare with classical Fickian diffusion.
