Topological Features of the Alluaudite-Type Framework and Its Derivatives: Synthesis and Crystal Structure of NaMnNi2(H2/3PO4)3

open access: yesCrystals, 2021
A new sodium manganese-nickel phosphate of alluaudite supergroup with the general formula NaMnNi2(H2/3PO4)3 was synthesized by a hydrothermal method. The synthesis was carried out in the temperature range from 540 to 660 K and at the general pressure of ...

Serum phosphate is not an early predictor of neurocognitive outcomes in acute carbon monoxide poisoning patients [PDF]

open access: yesClinical and Experimental Emergency Medicine, 2023
Objective Carbon monoxide (CO) poisoning causes brain injury by hypoxia and inflammatory mechanisms. Hypoxic conditions result in increased serum phosphate concentration due to loss of polarity of the cell membrane, changes in membrane fluidity, and ...

Guano-related phosphate-rich minerals in European caves

open access: yesInternational 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 ...

A Review on the Effect of Calcium Sequestering Salts on Casein Micelles: From Model Milk Protein Systems to Processed Cheese

open access: yesMolecules, 2023
Phosphates and citrates are calcium sequestering salts (CSS) most commonly used in the manufacture of processed cheese, either singly or in mixtures. Caseins are the main structure forming elements in processed cheese. Calcium sequestering salts decrease

FLUORIDE PHOSPHATE AND PHOSPHATE GLASSES FOR PHOTONICS [PDF]

open access: yesPhosphorus 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

open access: yesFrontiers 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 ...

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

open access: yesMolecules, 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.

Phosphate Uptake by Phosphate-Starved Euglena [PDF]

open access: yesThe Journal of general physiology, 1966
Phosphate-deprived Euglena acquire the ability to rapidly in-corporate added phosphate and, also, synthesize an induced acid phosphatase localized in the pellicle. The phosphate uptake system is saturated at low concentrations of phosphate and is inhibited by dinitrophenol, by low temperature, by K+, Li+, and Na+ ions, and competitively by arsenate ...
