Phase-structural heterogeneity and activity of the surface of polymineral sand powders [PDF]
Нанотехнологии в строительстве, 2022 Introduction. The value of the specific surface (Ssp), the degree of crystallinity (С, %) and surface activity (ks) plays an important role in creating various compositions.

Reactivity as one of the criteria for the selection of raw materials for the production of active fine mineral powders [PDF]
Нанотехнологии в строительстве, 2023 : Introduction. The simplest and most common method of obtaining fine mineral powder is mechanical dispersion. In the process of grinding the material went through some work (energy), which is spent on the formation of a new surface. Therefore, it is

Assessment of 137Cs in the Environment of Hetauda City, Nepal by In-Situ Gamma Ray Spectrometry
Atom Indonesia, 2023 A significant amount of 137Cs radioactive fallout have been spread in the atmosphere due to nuclear weapon testing and nuclear reactor disasters. This fallout eventually settles on the Earth's surface, and because 137Cs has a long half-life, it remains ...

Mechanics of active surfaces [PDF]
Physical Review E, 2017 We derive a fully covariant theory of the mechanics of active surfaces. This theory provides a framework for the study of active biological or chemical processes at surfaces, such as the cell cortex, the mechanics of epithelial tissues, or reconstituted active systems on surfaces.

Activity of surface active substances determined from their surface excess [PDF]
Physical Chemistry Chemical Physics, 2005 Commonly, the surface excess is determined from surface tension measurements via the Gibbs equation. This equation relates the activity (chemical potential), the surface excess, and the surface tension. When knowing two out of the three quantities, the third one can be calculated.

SPERMICIDAL ACTIVITY OF SURFACE-ACTIVE AGENTS [PDF]
Reproduction, 1962 Summary. The spermicidal activities against human spermatozoa of a range of non-ionic, anionic and cationic surface-active agents have been determined with the method of Baker, Ransom & Tynen (1937). Although it has been concluded that surface-tension-lowering properties do not directly influence spermicidal ...

Surface profile prediction and analysis applied to turning process [PDF]
, 2008 An approach for the prediction of surface profile in turning process using Radial Basis Function (RBF) neural networks is presented. The input parameters of the RBF networks are cutting speed, depth of cut and feed rate.

Palmitoylcarnitine, a surface‐active metabolite [PDF]
FEBS Letters, 1996 Palmitoylcarnitine is a well‐known intermediate in mitochondrial fatty acid oxidation. Less known are its properties as a surfactant, with a capacity to solubilize biological membranes similar to that of many synthetic detergents used in the biochemical laboratory.
