Potassium borates, which are widely used in welding and metal refining industry, as a lubricating oil additive, cement additive, fiberglass additive and insulation compound, are one of the important groups of borate minerals. In this study the production of a potassium borate mineral via hydrothermal method is aimed. The potassium source of potassium nitrate (KNO3) was used along with a sodium ...

Spirulina spp. is an alga from phylum Cyanobacteria that have multi-benefit due to their potential compounds like protein, carbohydrate, lipid, mineral, pigment, and phenolic compounds. Several types of research already describe capacity as antioxidant, anti-inflammation, antimicrobial agent, thus expand its application a food source, cosmeceutical, pharmaceutical compound. This study observed ...

2. Secondary mineral deficiencies are by far the most common of the two. Secondary deficiencies are derived from the consumption of one or more mineral antagonists that interfere with the normal metabolism of another mineral. A simple mineral evaluation of a feedstuff may suggest that adequate trace mineral concentrations are present; however, the presence of a mineral antagonist will decrease ...

Hydroxyapatite (HAp)/chitosan (CS) composites were synthesized via a one-step coprecipitation method from aqueous solution, with the use of calcium chloride (CaCl2) and disodium hydrogen phosphate (Na2HPO4). CS was obtained via partial deacetylation of chitin with the use of strong sodium hydroxide solution. Composites were prepared with various HAp/CS ratios (30/70, 50/50, 70/30, 85/15) for co...

In this Article, the compound '(R)-(–)-2-phenylpropionic acid' was incorrectly given as '(R)-(–)-2-methylphenylpropionic acid'. In the Results section under subheading 'Interference of the tropolone biosyn-thetic pathway of B. plantarii by PAA analogues' , " Among the PAA analogues tested, p-tolylacetic acid, (R)-(–)-2-methylphenylpropionic acid, and (p-isopropylphenyl)acetic acid inhibited tro...

This paper deals with the composition and properties of solid solution calcium sulfoferrite. It was studied an influence s sulfoferrite on structure cement phases. Study hydration processes mineral are observed only short prismatic crystals. Prismatic crystals ferruginous ettringite always formed from any fraction. it found that smaller initial hydrating grains minerals, faster they hydrated. A...

Abstract The main objective of this paper is to analyze various hydraulic oils and the effect additives like nanomaterials in order increase lubricity, counter friction, reduce wear, etc. A detailed list focused review which will enhance performance working fluid by enhancing lubrication, modifying viscosity cleaning engine deposits. Mineral or Synthetic hydrocarbon blends are used derive lubri...

Abstract The study aimed to investigate the temporal changes of pH, sorption complex, and structure soil organic matter through forest profile under beech spruce forests located in Jizera mountains (Czech Republic) affected by natural anthropogenic acidification. Soil samples were collected four different years (2008, 2013, 2015, 2020) each horizon: fermented horizons (F), humified (H), organo-...
