Melamine-phytate (MEL-PA) nanoflakes are formed by supramolecular self-assembly technology using melamine (MEL) and bio-based phytic acid (PA) as the building blocks. This work explores the possibility of this two-dimensional nanomaterial as flame retardant. The layered MEL-PA with the loading o...

The suppression effect of melamine cyanurate (MCA) and melamine polyphosphate (MPP) on the flame propagation of aluminum dust were studied experimentally. The results indicated that the concentration of MPP required to supress the aluminum dust explosion was lower than MCA. As the concentration ...

In this examine, melamine pyrophosphate (MPP) and aluminum hypophosphite (AHP) were selected as flame retardants. The synergistic effect between the MPP and AHP on flame retardancy and thermal stability of the polypropylene (PP)/wood flour (WF) composite were investigated. The thermal stability ...

A series of inorganic yellow pigments with general formula Y4–xAxMoO9+δ (A = Ta, Tb), where x = 0, 0.05, 0.1, 0.2, 0.4 for Ta and x = 0, 0.005, 0.01, 0.03, 0.05 for Tb, were synthesized by a conventional ceramic method at 1400 °C for 6 h in air. The samples were characterized by XRD, EDS, XPS...

Natural pigments have captivated pharmaceutical, food, textile and cosmetic markets because of its low toxicity as compared to synthetic pigments. Microorganisms, especially bacteria are the diverse source of natural pigments. The present study is performed with the aim to investigate different ...

While zero valent aluminum (ZVAl) is a promising reductant for eliminating bromate from water, ZVAl is typically obtained from reagent grade aluminum. As used aluminum beverage can is the most common aluminum waste, it can be conveniently used to prepare ZVAl. Thus, in this study aluminum bevera...

Bicarbonate scavenges OH to form CO3− that enhances the bromate formation by ozonation. However, the role of CO3− in the bromate formation during ozonation has never been quantitatively investigated. Herein, we establish a quantitative approach for evaluating the role played by CO3− based on the...

The removal of pollutants from water using agricultural waste-based biomaterials is gaining extensive attention. In this study, biochar loading ruthenium oxide (RuO2/BC), a novel composite for bromate removal from drinking water, has been prepared by the impregnation method. Based on the single-...

Three typical catalysts of hydrogenation, Ru/C, Pt/C and Pd/C, are compared for the first time to eliminate bromate in water. As Ru/C, Pt/C and Pd/C are comprised of 5 wt% of metals and porous activated carbon, they exhibit similar morphologies and textural properties, as well as surface charges...

Bromate (BrO3−) is an anionic contaminant known possess carcinogenic potential. Although some studies have reported the occurrence of bromate in drinking water, very little is known about its presence in fruits and vegetables, especially in Chile. In this study, we quantified bromate in soils (n...

Ferric chloride modified lotus stem-based porous carbon (FeCl3-LSPC) was synthesized for the removal of bromate from aqueous solutions. The adsorbent characterization indicated that the BET surface area and pore volume were enlarged by the modification of FeCl3, at the same time, the reductive f...

The classification of bromate as possibly carcinogenic for humans has led to an increasing interest of researchers in the development of effective technologies for its removal from water. Catalytic reduction of bromate into bromide in water under hydrogen flow was studied in detail using Pd and ...

Chemical oxidation processes have been extensively utilized in disinfection and removal of emerging organic contaminants in recent decades. Some undesired byproducts, however, are produced in these processes. Of them, bromate has attracted the most intensive attention. It was previously regarded...

Linoleic acid (18:2n-6), linolenic acid and eicosatrienoic acid stimulated fluid reabsorption in locust rectum. Only 18:2n-6 was able to enhance phospholipase C activity, inositol(1,4,5) trisphosphate production and to increase cytosolic free Ca2+ concentrations in epithelial cells via the openi...

Metabolism of long-chain fatty acids is impaired in both fasting and diabetes mellitus. A decrease in insulin activity simultaneously reduces the activity of the delta-9, delta-6, and delta-5 desaturases with respect to fatty acids either synthesized by the animal (palmitic and stearic acids) or...

1.1. The metabolic fate of 1-14C-acetate administered to the marine bivalve mollusc Mytilus edulis was investigated.2.2. The active incorporation of the label in 20:2 non-methylene-interrupted dienoic (NMID) fatty acids was found.3.3. Acetate incorporation patterns and specific radioactivity of ...

We have studied the acetylenic fatty acid 20:2Δ8a, 11a (eicosadiynoic acid, EDYA). It was found that this compound acts as an inhibitor of several steps in the production of icosanoids from arachidonic acid. First, the compound was shown to inhibit arachidonate uptake by platelets. Second, usin...

1.1. Characterization of fatty acid composition of hydrocarbon seep mussels reveals that the mussels contained a striking diversity of nonmethylene-interrupted dienoic (NMID) and trienoic (NMIT) fatty acids.2.2. The concentrations of the NMI acids are unusually high, accounting for 12.2–17.7% o...

Two fatty acids differing from arachidonic acid in lacking one of the internal double bonds (20:35,8,14 and 20:35,11,14) and their 1-C14 and acetylenic analogues were synthesized. 20:35,8,14 was not metabolized by human platelets but 20:35,11,14 yielded a small amount (1.5% conversion) of two hy...

Fatty acid drug discovery (FADD) is defined as the identification of novel, specialized bioactive mediators that are derived from fatty acids and have precise pharmacological/therapeutic potential. A number of reports indicate that dietary intake of omega-3 fatty acids and limited intake of omeg...
