• The combination of a high surface hardness and a low surface coefficient of friction of the borided layer also makes a significant contribution in combating the main wear mechanisms: adhesion, tribooxidation, abrasion, and surface fatigue. This fact has enabled the mold makers to substitute e...

Yutongling reacts with it to form a yellow complex. The absorbance value is determined at a specific wavelength, and the results are automatically calculated by built-in curve formula. According to the situation of water samples, in order to avoid interference ions affecting the analysis accuracy...
Analogically, there is no single parameter for antioxidant status of food and biological fluids that corresponds to the widely accepted 'French hardness parameter' of water, defined as the mg-amount of CaCO3-equivalent hardness per 100 mL of water. Everybody understands the same meaning from a ...
Noun1.surface area- the extent of a 2-dimensional surface enclosed within a boundary; "the area of a rectangle"; "it was about 500 square feet in area" expanse,area extent- the distance or area or volume over which something extends; "the vast extent of the desert"; "an orchard of ...
“supramolecular” polymer and imparts to the thereby modified bitumen the properties of a conventional bitumen/polymer composition, notably as regards hardness. At the temperatures of use, the gelling due to the aggregation of the organogelator derivatives causes thickening of the bituminous medium, ...
(a) and at least one copolymer (b) resulting from the copolymerization of: at least one monomer selected from: acrylic acid and any salt thereof, optionally at least one monomer selected from: methacrylic acid and any salt thereof, at least one monomer selected from the monomers of formula ...
Total hardness as high as 1000 mg·L 1 however, did not have a significant effect in the growth rate or survival as long as the alkalinity was 100 mg·L 1 or lower. Thus suggesting that water with high hardness and low alkalinity in different countries could be used for the production ...
