Guano-related phosphate-rich minerals in European caves

International Journal of Speleology, 2019
Guano is a typical deposit found in caves derived from the excretions of bats and in minor cases of birds. These organic deposits decompose and form a series of acid fluids and gases that can interact with the minerals, sediments, and rocks present in ...

The Role of Sulphate and Phosphate Ions in the Recovery of Benzoic Acid Self-Enhanced Ozonation in Water Containing Bromides

Molecules, 2021
The ozonation of aromatic compounds in low-pH water is ineffective. In an acidic environment, the decomposition of ozone into hydroxyl radicals is limited and insufficient for the degradation of organic pollutants.

FLUORIDE PHOSPHATE AND PHOSPHATE GLASSES FOR PHOTONICS [PDF]

Phosphorus Research Bulletin, 2002
Phosphate (P) and fluoride phosphate (FP) glasses are attractive materials for a wide range of photonic applications such as lasers, amplifiers, photosensitivity, optical storage and Faraday rotators. They demonstrate high W transmission, low linear and nonlinear refractive index, low viscosity and low melting temperatures, athermal behaviour.

Climate variability, pastoral and agro-pastoral livestock systems, and human nutrition in African drylands: a PRISMA-based systematic review of evidence, pathways, and policy implications

Frontiers in Nutrition
Livestock-based livelihoods underpin food security, dietary quality, and resilience in African arid and semi-arid lands (ASALs), yet the mechanisms linking livestock systems, food environments, and human nutrition under climate variability remain ...

Mechanical and thermal properties of PEEK composites by incorporating inorganic particles modified phosphates

, 2021
This work aims to improve heat resistance and mechanical properties of PEEK composites by filling the modified phosphates with inorganic particles (Si3N4, AlN, Al2O3 and Cu2O) as reinforcements.

Inhibitory activity of phosphates on moulds isolated from foods and food processing plants [PDF]

, 2005
Inhibition by six commercial phosphates on the growth of 17 molds isolated from food sources was investigated. The assays were performed at neutral and natural (without pH adjustment) pH values, streaking the molds on PCA-phosphate (Plate Count Agar with

Effectiveness of different precipitated phosphates as phosphorus sources for plants

, 2003
Eleven precipitated phosphates were evaluated as sources of phosphorus (P) for plant growth by comparing their effectiveness with that of monocalcium phosphate, a source of water-soluble P that is generally considered to be fully plant available.

A thermochemical approach for calcium phosphate precipitation modeling in a pellet reactor [PDF]

, 2003
A common pathway for P-recovery from wastewater is phosphate precipitation as calcium phosphates. In this paper, a thermodynamic model for phosphate precipitation is proposed based on various models of activity coefficients taking into account various ...
