“…Various nanostructures such as zinc oxide, silver, tin, nickel and nickel based alloy have been successfully grown by using PAA templates. 8,[10][11][12] Researchers tend to focus on the investigation of the properties and characteristics of those nanostructures instead of the parameters on PAA itself, even though the properties of PAA could influence the nanostructured material synthesis. The internal defects of aluminium such as grain boundary were discussed to be the reason of disordered pore formation and the small grain size of aluminium film also limited the pore distance and diameter of PAA.…”

This article reports on the comparative study of the fabrication of porous anodic alumina films by anodisation of the aluminium films on glass substrates which were deposited by direct current sputtering and electron beam evaporation methods. The relationship between surface morphology of the deposited aluminum films and porous anodic alumina films was investigated. A more uniform and ordered porous anodic alumina was obtained by fabricating from electron beam evaporation deposited aluminium film with smaller and compact grains. Two-step anodisation was used to further improve the quality of porous anodic alumina compared to one-step anodisation. The optical transmittance spectra within wavelength of 370–800 nm were obtained and the optical properties were studied.

“…The recycled coarse aggregate from building waste concrete has also been experimental studied by many researchers [2]. For the researches of the resistance of reinforced recycled-concrete beam, the studies concentrated on the effect of different replacement ratio of recycled coarse aggregate, the experimental method was commonly used to compare the ordinary reinforced concrete beam in the same condition, the axial compressive strength of concrete for calculation was always converted from the test cubic compressive strength [3][4][5][6][7][8][9].…”

With silicon powder content and the hybrid fiber content as parameters, will be 1 as ordinary concrete beams and the control group, three different content of silicon powder and 2 root hybrid fiber volume content of beam as the experimental group, the modification of the flexural performance of recycled concrete beams is analyzed, the results show that modified regeneration of recycled concrete and ordinary concrete beams and damage has obvious four stages of the process, and its basic mechanical process also accord with flat section assumption; And with silicon powder and the mixed hybrid fiber recycled concrete beams is made of modified flexural performance enhancements, cracking resistance and ultimate bearing capacity is better than that of recycled concrete beams is ordinary; And the ultimate bearing capacity of normal section of the calculated in accordance with the specification was consistent with the test results, the modified recycled concrete can be carried out in accordance with the specification design, provides a reference for engineering practice.

“…Therefore, it is significant to deeply study the preparation process of yttrium oxide and formation mechanism, and to prepare ultrafine yttria powders with specific morphology and size. Currently, the method of wet chemical procedures to prepare ultrafine yttria included alkoxide hydrolysis, urea hydrolysis, sol-gel method, hydroxide precipitation, carbonate precipitation, hydrothermal synthesis method etc [1][2][3][4][5][6][7]. In previous researches, we have observed the effect of the precipitation conditions of yttria precursor on the grain size and morphology by preparing yttria with precipitating agents of ammonia, ammonium carbonate and ammonium tartrate [6,7].…”

The precursor of yttria was prepared by yttrium nitrate and ammonium oxalate in water solution. Pyrolysis behavior of the precursor and the characterization of yttria phase transformation were studied through thermoanalysis. The grain growth kinetic behavior of yttria nanopowders was investigated by the X-ray powder diffraction (XRD) result of the powders obtained through roasting the precursor. Pattern of the yttria powders and agglomeration of its grain were measured by means of SEM and laser particle size analysis methods. The results suggested that cubic crystal phase yttria could be obtained by sample calcination for 1 h under 823 K. When the precursor was calcined under conditions of temperature ranging from 823 K to 1173 K, yttria grain ranging 7 nm ~ 16 nm could be obtained ,with grain growth exponent of n< 0.2 . In addition , an significant increase in grain-growth-rate constant was observed as the temperature went up. The higher temperature, the faster growth. Grain growth activation energy was different in low-temperature and high-temperature fields. The activation energy was 77.42 kJ•mol-1 when the temperature was lower than 965 K, and became 524.36 kJ•mol-1 when the temperature was higher than 965 K. Yttria powders is highly dispersed whose agglomerates sized about 400 nm after being dispered in deionezed water.
