Environmental and Food Contamination by Phthalic Acid Esters (PAEs): Overview

open access: yesWater, Air and Soil Pollution
Phthalic acid esters (PAEs) are dialkyl or alkyl/aryl ester derivatives of phthalic acid. PAEs are colorless, odorless, and flavorless oily liquids. PAEs are the main plasticizers used in industry and households.

Characteristics of the root exudate release system of typical plants in plateau lakeside wetland under phosphorus stress conditions

open access: yesOpen Chemistry, 2020
In this study, the root exudates of wetland plants, Pistia stratiotes, black algae, and Cyperus alternifolius, exposed to six phosphorus concentration gradients (0, 0.2, 1, 5, 10, and 20 mg/L) were characterized.

Synthesis and characterization heterocyclic of compounds derived fromamino pyridine substituted

open access: yesTikrit Journal of Pure Science, 2023
In this study, heterocyclic derivatives of imidazole, pyrimidine, benzodiazepine, indole and benzimidazole were synthesized. These new compounds were formed through the condensation reaction between 2-aminopyridinederivative with4-phenylphenacyl bromide,

Mechanism of phthalic acid collector in flotation separation of fluorite and rare earth

open access: yes, 2020
The mechanism of phthalic acid, a dicarboxylic acid collector, in flotation separation of fluorite and rare earth (RE) is studied in this paper. The experimental data of flotation shows that phthalic acid, as the collector, can realize highly efficient ...

Chromatographic and mass spectrometric characteristics of monoesters of phthalic acid [PDF]

open access: yes, 2016
In contrary to the widespread and thoroughly characterized disubstituted esters of benzene-1,2- dicarboxylic (phthalic) acid, their primary metabolites — monosubstituted esters of phthalic acid — have not yet to be characterized with standard mass ...

Anaerobic degradation process of phthalic acid esters

open access: yes浙江大学学报. 农业与生命科学版, 2006
Ten phthalic acid esters (PAEs) were tested anaerobically to assess their potential for biogas production. Results showed that biogas production decreased with the increasing alkyl chain length of PAEs resulting in its increased half-life.

Phthalic acid mimics 17β-estradiol actions in WISH cells

open access: yes, 2001
The object of this study was to evaluate whether phthalic acid, which is one of the metabolites of phthalic acid esters, exerts estrogenic actions in WISH cells, an immortalized cell line derived from human amniotic tissue.

Near‐Infrared‐Driven Metal–Organic Frameworks‐Based Nanorobots for Controlled Photothermal‐Chemical Therapy Synergistic Induction of Cancer Cell Death

open access: yesAdvanced Robotics Research, EarlyView.
To achieve efficient cancer cell death, a bowl‐shaped PDA@UiO‐66@DOX nanorobot drug‐delivery nanoplatform was developed. Near‐infrared irradiation not only drives the nanorobot to exhibit self‐thermophoretic motion and elevates temperature but also triggers Doxorubicin (DOX) release via hyperthermia, enhancing cancer cells uptake of DOX and thereby ...
