This characteristic generates a material with a high specific surface even for particles that are not small in size (Ferraro; Nanni, 2012). Desired for this characteristic, the use of RHA as SCM is limited to a low to moderate volume, since high volumes of use will cause the mixture to dry (Aprianti et al., 2016).

The LA-ICPMS results for perovskite from the Southern carbonatite stock indicate its somewhat older age (255.3 ± 2.4 Ma), implying the possibility of small-volume mantle magmatism predating the eruption of the Siberian flood basalts at ca. 252–251 Ma. This interpretation is supported by reports of pre-flood magmatism elsewhere in eastern ...

Microfluidics is both the science which studies the behaviour of fluids through micro-channels, and the technology of manufacturing microminiaturized devices containing chambers and tunnels through which fluids flow or are confined. Microfluidics deal with very small volumes of fluids, down to femtoliters (fL) which is a quadrillionth of a liter. Fluids behave very differently on the ...

work in small mills. The trends in number and size of sawmills are expected to continue for the next few years. In this and prior studies, small sawmills were found to be processing most of the softwood. As the number of small mills has declined, output of softwood logs has also dropped. Softwood log output in 1970 was less than half that in 1960.

A lower residue in a given separation sieve means higher milling efficiency for the parameters used in the process. The lower loading of the mill, with 70% of the volume available for milling, together with a lower viscosity of the slip using water without addition of wastewater, was the best condition for milling in the 4th hour of the process.

Here, we describe our recent progress in developing techniques for extracting small volumes of aerogel, which we have called "keystones," which completely contain particle impacts but minimize the damage to the surrounding aerogel collector. These keystones can be fixed to custom-designed micromachined silicon fixtures (so called "microforklifts").

Structural changes of ground SiO 2 glass were investigated using X-ray diffraction (XRD), Fourier transform infrared (FT-IR) spectroscopy, and Raman spectroscopy. SiO 2 glass samples were ground in a ball mill for up to 500 h. Reduction in the particle size of ground SiO 2 glass samples was observed up to ∼ 80 h of milling. After 80 h of milling, the particle size of ground SiO 2 …
