Silver
nanoparticles of size 10-30 nm were prepared in a gelatin stabilized AgNO3 solution under
reduction with K-Na-tartrate.
This paper presents the results of work on the laser irradiation of silver colloids prepared by the chemical reduction method.
Experimental Silver colloids were prepared by the reduction of a gelatin stabilized ammonia-containing AgNO3 solution with K-Na-tartrate.
Electron diffraction data evidence shows that these structures are not compact but are made up of a great many small silver particles.

However, the presence of nanoscale ‘separations’ on the thin film annealed over Tm (AN160) suggested high possibility of defects, and hence a reduction in ferroelectric properties of thin films.
SUBSEQUENTLY, FURTHER ANNEALING TO TEMPERATURE OF 160°C CAUSED A REDUCTION IN THE PR FOR AN160 FILMS, WHICH MAY BE ATTRIBUTED TO THE APPARENT DEFECTS OBSERVED EARLIER FROM THE ‘SEPARATION’ BETWEEN THE FIBROUS-LIKE CRYSTALLITES IN THE AN160 FILMS.
The presence of nanoscale “separations” on the thin films annealed above melting temperature (AN160) suggested a high possibility of electrical defects, hence a reduction in ferroelectric properties of the PVDF-TrFE thin films.

To analyze the data for the setup used during this study, a one dimensional model was used
assuming an infinite source of the dye.
The diffusion data thus obtained were validated with the theoretical values from the literature and also used as reference to compare with the diffusion results through the diatom stuck capillary.
The data shown here represent fluorescence intensity values taken every 30 s, over a time period of 20 minutes.
The continuous lines represent the theoretical curves and the symbols represent the experimental data.
The bottom curves of Fig. 4 show that the diffusion data fit quite well with the theoretical curves with diffusivity value of 3.1×10-11m 2s-1.

The proposed damage index uses data on exclusively mode shape curvature from the damaged structure.
In order to ascertain the sensitivity of the proposed method for noisy experimental data, numerical mode shapes are corrupted with different levels of random noise.
However, the major drawback of those methods is the need for data on the healthy structure, which sometimes can be difficult or even impossible to obtain.
Several sets of simulated data were used for investigating the effectiveness and applicability of the proposed algorithm for detecting and locating damage in plate-like structures.

Abstract: The solar reflective green coating is prepared in the paper, of which the tailored infrared property reaches near upon 80%, and the temperature reduction bring by the reflectivity of the coat is improved too.
The experiments on the temperature reduction and aging performance of the coat are also performed, the results suggests the green solar reflective coating can reduce more than 10℃ compared with the same type coatings, it also has a good aging resistance capability.
From the statistical data, the average reflectivity of the coat from 90 nm to 1650 nm is 74.2%, the highest of it is 79%.
The datum showed that the coating prepared in according to the new ingredients is better than what we have. [7] Aging test of the coating The degree of the color change and pulverization is from 0-5 according to the GB/T 1766-1995, one period are 250 hours for the eligible coating in the LUV-1.

The results show: the reduction of pile spacing and the settings of pile cap can decrease the settlement of soil among the piles on foundation plane.
The data indicates that the reduction of pile spacing can decrease settlement in large scale.
In a word, both the reduction of pile spacing and setting of pile caps can decrease the settlement of soil among piles. 2) Settlement regularity of soil among piles in pile-tip layer The settlement of soil among piles in pile-tip layer appears to be basin shape.
Conclusions By establishing a three-dimensional model, this paper analyzed the settlement regularity of deep soft soil and drawn the conclusions as follows: 1) The reduction of pile spacing and setting of pile cap can decrease the settlement of soil among piles on foundation plane; 2) The impact of pile caps acted on soil among piles is different under variable filling height situation.

Results showed that Cd decreased the chlorophyll content of young leaves, accompanied by a significant shoot and root biomass reduction across all Cd treatments.
Data were tested for statistical significance using the software of SPSS for Windows.
It was suggested that Cd-induced reduction of SOD could be responsible for an inactivation of the enzyme by H2O2 produced in different compartments, where SOD catalyses the disproportionation of superoxide radicals.

Finally
the assessment method based on S-N curve and in-situ monitoring data was applied to a case study
bridge.
According to the monitoring data, the characters and effect of overloading and oversize trucks can be analyzed in-depth for the further research.
How to choose an appropriate S-N curve is very important if the test data is absent.
On the base of monitoring data and considering traffic volume increase prediction, the calculation result showed that the fatigue life of deck beam for Qilangwo Yellow River Bridge was 418 years.
The first method was applied to the case bridge, and the fatigue life of the bridge was estimated using the monitoring data and considering traffic volume increase rate.

By this way a reduction in thrust force and torque is expected, having temporarily changed the material properties.
The reduction of lubricants is also expected, making the issue very important for ecological and economic reasons.
The signals were sent to a digital data acquisition system for storage and subsequently, a computer was used for data handling and analysis.
The reduction relative to Mz, with a minimum of 80°C, appears especially significant.
Tab. 4 reports the maximum force thrust and torque reduction percentage in hot drilling of Al6061/SiCw.

The United States first legislated to impose carbon tariffs on imported products of the countries including China, which don’t implement carbon emission reduction quotas since 2020.
Carbon tariffs are directly related to the reduction of CO2 emissions, because it will increase the cost of foreign polluters and encourage them to reduce CO2 emissions.
