This is frequently combined with additional functionality of film, such as chemical and thermal stability, increased hardness, protection again corrosion, electromagnetic shielding, reduction in consumption of precious materials, etc.
Alumina-supported Silver catalysts have been examined extensively in the environmental chemistry (photocatalytic reduction of nitrogen oxides NOx and CO2), and also as anti-bacterial agent in pharmaceuticals.

Recently many researches on reduction of cement have been performed and these can be summarized as two research field.
The relation between compressive strength and bond strength for all data can be plotted in Fig.9.
In the case of FA replacement ratio of 35% and 50%, shear strength shows reduction to 77% and 60.1% of shear strength in OPC concrete, respectively.

It can be observed a significant particle size reduction after milling for both powders.
The lattice parameters and the crystallite size of the ZrB2-TiB2 solid solutions were calculated by Maud program with adjustment of the pattern file 1510845 (Ti0.5Zr0.5B2) and 1510856 (ZrB2) which were choosen among various data in Crystallography Open Database (COD).
The fracture aspect for all compositions was transgranular and a reduction of ZrB2 grain size with the increasing TiB2 content can be observed for both sintering process.

2.3 Sharpening of cutting edge by polishing flank face
The UV-polishing properties of PCD substrates indicated valuable results such as the smooth surface and the reduction of particle gap between the adjacent diamond particles.
Evaluation of cutting performance of sharpened and chamfered PCD tools Workpiece Data logger Amplifier Computer Dynamometer (KISTLER 9257B) Cutting tool NC lathe (TAC-650) Fig.6 Experimental system for cutting tests Table 2 Experimental conditions of cutting tests Workpiece Al-17%Si alloy (100 mm in diameter, 500 mm in length) Cutting tool Sharpened PCD-C tool and chamfered PCD-A, -B, -C tools Rake angle: 0º, Relief angle: 11º, Nose radius: 0.8 mm Cutting speed 471 m/min Depth of cut 0.2 mm Feed rate 0.15 mm/rev Cutting distance 1400 m The cutting tests were conducted to evaluate the cutting performance of four kinds of PCD tools: a sharpened PCD-C tool and chamfered PCD-A, PCD-B and PCD-C tools.
The reduction effect of tool wear amount by chamfer is more effective on the flank face than the rake face.

In addition, when we considered at the constant reaction temperature and studied the influence of reaction time, the data indicated that %WI of corn husk laurate increased with the increasing of reaction time until it approached the maximum value and then gradually decreased.
As shown, there was a slight reduction in the tensile strength and elongation at break as the exposure time increased in both of landfill and wastewater treatment conditions.
The reduction in tensile properties of cellulose laurate film also confirmed the degradation.

The twoparameter
Weibull statistics was applied to the ranked cumulative probabilities of the maximum
flexural stress data [5].
That led to reduction of the thermal conductivity by about 35% of value and increase of CTE by 20% after 1000 cycles, whereas a stronger bonding between the reinforcement and matrix resulted in reduction of the thermal conductivity by 10% upon thermal cycling.

The data were dotted in Fig. 4.
Oil absorbency exhibited slight reduction, with around 86.2 wt% of retention after six cycles of absorption/desorption.
This reduction is presumably due to the reason that part of PBMA was washed away since not all PBMA was crosslinked during polymerization.

The paper collects plenty of socio-economic and hydrological data of the Weihe River basin and establishes numerical models for comprehensive simulation of socio-economic system and water resources system, including CGE model, ROWAS model and WEP model.
It’s indicated that, based on analysis of results by CGE model, water consumption structure adjustment of transferring water consumption from agriculture to industry and services may promote economic growth and social progress with the increase of GDP, rural income and expense, urban income and expense, and reduction of total labor surplus rate.
The surface water supply decreases as a result of reduction of agriculture water consumption mainly because of its low cost in process of exploiting surface water resources.

The main advantages of the SMC are disturbance rejection, order-reduction in system dynamics, strong robustness and simple implementation via power converters.
The sampling frequency of the data acquisition system is 100 Hz.
However, PID controllers cannot solve all desired requirements [21], and different tuning algorithms must be used for different needs such as disturbance reduction tuning [22] and optimization tuning [23].

This reduction of Tg caused by the plastizing effect of ionic liquid which disrupts the semi-crystallinity structure of PEO making it more amorphous [8, 9].
The reduction of Tm suggests that the interaction between the polymer host backbone and NaCF3SO3 affects the main chain dynamics of the polymer.
