Over the last two decades, we have developed a number of advanced boiler technologies for high efficiency coal-fired plants.
(a) Austenitic steels Steam oxidation resistance of austenitic steels strongly depends on Cr contents and grain size.

Structural model and calculation of QD-IBSC P+-N--N+ structure was adopted to design the QD-IBSC, where the spherical nano-crystals such as nano-crystalline CdTe, Si and Ge grains can be employed as QDs to embed in N- type doped absorption layer.
As for the doped QDs, discrete quantized impurities’ levels shift below the corresponding QDs’ electronic levels and develop into the impurity bands with increasing the number of impurities, which was confirmed by an elsewhere experimental observation [20], thus can effectively heighten the density of states in IB and can exalt transmission possibility from VB via IB to CB and hence elevate the Jsc with a subsequence of the η.

Due to the great number of alloys involved, iron-base hardfacing alloys are best classified by their suitability for different types of wear and their general microstructures rather than by chemical composition.
Comparison of nonferrous hardfacing alloys to tool steel and carbon steel reference materials using ASTM G 65 low-stress, abrasion test parameters are: procedure B; room temperature; 13.6 kg load; quartz grain sand diameter of 212 to 300 μm; 2000 rev at 200 rev/min; 390 g/min feed rate.

After 24 hours of drying, a gradual onset of latex deformation and film formation was observed, but still a large number of latex particles maintained their spherical shape and did not coalesce into a film.

In line with XRD findings and related to particle agglomeration, the average grain size has likewise grown as the sulphur content has increased.

A large number of studies, in this area, has been reviewed and documented.
Then, Nital acid was poured onto the surface to reveal the grains orientation.

Pfost and Young [11] reported that the addition of bentonite at an inclusion rate of 100 kg/ton of feed mash significantly improved the durability of the poultry feed consisting of ground yellow corn, ground sorghum grain, and soymeal ingredients.
Sieve numbers 16, 20, 30, 50, 70, and 100 (sieve opening sizes: 1.190, 0.841, 0.595, 0.297, 0.210, and 0.149 mm, respectively) were used.

The grain size of the molybdenum sulfide powder used in this study is less than 2μm, which was purchased from Zhongnuoxin Material (Beijing) Technology co., LTD.
The reason for this is that catechol REDOX occurs in acidic and alkaline solutions, where the number of protons and electrons are equal.

The structural information on individual out-of-plane interplanar spacings (at ψ=0), number of planes, as well as intra- and inter-layer fluctuations may be obtained through a refinement procedure which consists in fitting a theoretical model to the experimental θ-2θ XRD spectra (see Fig. 2).
This tensile stress in Mo can no longer arise from ion-irradiation induced vacancies creation or grain growth since the same effect should be also observed for Ni.

Turmeric was then authenticated by the Forest Herbarium, Bangkok, Thailand (BKF number 194769).
