Here, we have successfully synthesised and purified multifunctional PLGA-based nanoparticles by the co-encapsulation of an anticancer drug (tetrandrine) and a magnetic material (Fe3O4). The obtained Tet-Fe3O4-PLGA NPs had a uniform spherical shape with a particle size of approximately 199nm and a negative surface charge of -18.0mV, displaying a high encapsulation efficiency. Furthermore, TEM studies provided representative images of the purification process of the magnetic nanoparticles with MACS((R)) technology. The MFM and VSM results indicated that both the Fe3O4 NPs and Tet-Fe3O4-PLGA NPs were superparamagnetic. The DSC spectrum demonstrated that Tet was successfully encapsulated within the PLGA-based nanoparticles. Significantly, the release studies revealed NPs had a relatively slower release rate than free Tet after 8h’s initial burst release, which had decreased from 98% to 65% after 24h. In vitro cellular studies revealed that NPs could effectively penetrate into A549 cells and A549 multicellular spheroids to exert cytotoxicity, displaying a significantly high anti-proliferation effect. Moreover, western blot demonstrated that the co-loaded NPs had a higher anticancer activity by injuring lysosomes to activate the mitochondria pathway and induce A549 cell apoptosis. The magnetic characteristics and high anticancer activity support the use of Tet/Fe3O4 co-loaded PLGA-based nanoparticles as a promising strategy in the treatment of lung cancer.

Ammonia (NH3) electro-oxidation reaction (AOR) is an important reaction in direct NH3 fuel cells, NH3 electrolyzer, and NH3-based electrochemical sensors. However, its slow kinetics and structure-sensitive properties require specific electrocatalyst designs. In this study, Ir-decorated N nanocubes are developed as unique surface engineered model catalysts. For the first time, we find that a trace amount of Ir (less than 2%) could increase the AOR activity of N nanocubes by more than twice. Theoretical simulation results also illustrate that the surfacedecorated Ir could lower the energy barrier in the rate determining *NH formation step on N surfaces, thus increasing activity in accordance with experimental findings. Additionally, Ir and Ni(OH)(2)-decorated N nanocubes can significantly improve the durability. Our findings demonstrate the importance of surface engineering in catalyst synthesis and pave the way of advanced electrocatalyst designs for ammonia oxidation and other catalytic reactions.

Electronic waste (E-waste) recycling is a rapidly growing occupation in the USA with the potential for elevated exposure to flame retardants and metals associated with electronic devices. We previously measured polybrominated diphenyl ethers (PBDEs) in plasma from E-waste workers and found them similar to non-E-waste workers. This study focused on structurally related PBDE derivatives, the hydroxylated (OH-PBDEs) and methoxylated (MeO-PBDEs) forms along with metals known to occur in E-waste. Humans can metabolize PBDEs and some MeO-PBDEs into OH-PBDEs, which is a concern due to greater health risks associated with OH-PBDEs. We measured 32 different OH-PBDEs and MeO-PBDEs in plasma samples provided by 113 volunteers living in the greater Puget Sound region of Washington State, USA. We measured 14 metals in a subset of 10 E-waste and 10 non-E-waste volunteers. Volunteers were selected based on occupational and dietary habits: work outdoors and consume above average amounts of seafood (outdoor), electronic waste recycling (E-waste) or non-specific indoor occupations (indoor). A two-week food consumption diary was obtained from each volunteer prior to blood sampling. OH-PBDEs were detected in all volunteers varying between 0.27 and 102 ng/g/g-lipid. The MeO-PBDEs were detected in most, but not all volunteers varying between n.d. 60.4 ng/g/g-lipid. E-waste recyclers had OH-PBDE and MeO-PBDE plasma levels that were similar to the indoor group. The outdoor group had significantly higher levels of MeO-PBDEs, but not OH-PBDEs. Comparison of plasma concentrations of BDE-47 with its known hydroxylated metabolites suggested OH-PBDE levels were likely determined by biotransformation and at least two subpopulations identified differing in their apparent rates of OH-PBDE formation. The metals analysis indicated no significant differences between E-waste workers and non-E-waste workers. Our results indicate E-waste workers do not have elevated plasma levels of these contaminants relative to non-E-waste workers. (C) 2020 Elsevier B.V. All rights reserved.

The Name is Diphenyl oxide. Through research, I have a further understanding and discovery of 101-84-8.

Waste printed circuit boards (PCBs) contain a high level of brominated flame retardants (BFRs), among which polybrominated biphenyl ethers (PBDEs) are the most widely used additive BFRs. PBDEs are considered to be a type of persistent organic pollutants (POPS). The efficient removal/degradation of PBDEs in waste PCBs is an urgent problem in electronic waste treatment, but the degradation of PBDEs is a great challenge due to their extreme stability and persistence in nature. In this study, a novel management strategy was developed for removal and degradation of PBDEs in waste PCBs by using a simple subcritical methanol (SubCM) process. The results showed that reaction temperature, residence time, solid-to-liquid ratio, and additive NaOH are key factors influencing the removal of PBDEs from waste PCBs. Under optimal conditions (200 degrees C, 60 min, 1:20 g/mL), the removal efficiency of Sigma(8) PBDEs from waste PCBs could reach 91.3% and 98.8% for the proposed process of SubCM and SubCM + NaOH, respectively. When the temperature is below 200 degrees C, highly brominated PBDEs congeners in waste PCBs were degraded into 2,’3,4′,6-Tetrabromodiphenyl ether (BDE71) and 2,4,4′-Tribromodiphenyl ether (BDE28) after SubCM treatment. 4-Bromophenyl ether (BDE4) and diphenyl ether were generated by the further debromination of BDE71 and BDE28 with the increase of treatment temperature. The debromination temperature of PBDEs congeners in SubCM could be markedly lowered by adding 4 g/L of NaOH. The complete debromination of PBDEs congeners in waste PCBs could be achieved at 300 degrees C and 250 degrees C for the developed process of SubCM and SubCM + NaOH, respectively.

A micro fabricated chip-based wearable air sampler was used to monitor the personnel exposure of volatile chemical concentrations in microenvironments. Six teenagers participated in this study and 14 volatile organic compounds (VOCs) including naphthalene, 3-decen-1-ol, hexanal, nonanal, methyl salicylate and limonene gave the highest abundance during routine daily activity. VOC exposure associated with daily activities and the location showed strong agreements with two of the participant’s results. One of these subjects had the highest exposure to methyl salicylate that was supported by the use of a topical analgesic balm containing this compound. Environmental based air quality monitoring followed by the personnel exposure studies provided additional evidence associated to the main locations where the participants traveled. Toluene concentrations observed at a gas station were exceptionally high, with the highest amount observed at 1213.1 ng m(-3). One subject had the highest exposure to toluene and the GPS data showed clear evidence of activities neighboring a gas station. This study shows that this wearable air sampler has potential applications including hazardous VOC exposure monitoring in occupational hazard assessment for certain professions, for example in industries that involve direct handling of petroleum products.

The molecular diffusion coefficient is fundamental to estimate dispersion coefficients, convective mass transfer coefficients, etc. Since experimental diffusion data is scarce, there is significant demand for accurate models capable of providing reliable diffusion coefficient estimations. In this work we applied machine learning algorithms to develop predictive models to estimate diffusivities of solutes in supercritical carbon dioxide. A database of experimental data containing 13 properties for 174 binary systems totaling 4917 data points was used in the training of the models. Five machine learning algorithms were evaluated and the results were compared with three commonly used classic models. The best results were found using the Gradient Boosted algorithm which showed an average absolute relative deviation (AARD) of 2.58 % (pure prediction). This model has five parameters: temperature, density, solute molar mass, solute critical pressure and solute acentric factor. For the same dataset, the classic Wilke-Chang equation showed AARD of 12.41 %. The developed model is provided as command line program. (C) 2021 Elsevier B.V. All rights reserved.

In the present study, positive matrix factorization (PMF) and compound-specific isotope analysis were used to investigate the in situ biodegradation of polybrominated diphenyl ethers (PBDEs) in sediment cores collected from a pond at an e-waste recycling site in South China. The potential microorganisms relevant to the degradation of PBDEs were also assessed to aid in the understanding of in situ biodegradation. The PMF results suggested that reductive debromination took place in the sediments. The debromination signal (ratio of the concentration of factor S (PMF result) to the total PBDE content) was positively correlated with the relative abundance of Dehalococcoidetes at different core depths. The clear C-13 enrichment of five PBDE congeners (BDE 28, 47, 49, 99, and 153) with increasing core depth indicated that a measurable change in isotope fractionation might have occurred during PBDE biodegradation. The in situ biodegradation was further validated by the widespread detection of mono-BDE congeners (BDE 2, BDE 3) and diphenyl ether in the sediments. This study provides new evidence to enhance our understanding of the in situ biodegradation of PBDEs and suggests that the extensive removal of bromine from PBDEs was mediated by indigenous microorganisms at the e-waste site.

The hydrated electron (e(aq)(-))-based reduction processes are promising for removing organic pollutants in water engineering systems. The reductive kinetics, especially the second order rate constants (k(eaq-)) of e(aq)(-) with organic compounds, is important for evaluating and modeling the advanced reduction processes. In this study, the k(eaq-) values for aliphatic compounds and phenyl-based compounds are, for the first time, modeled by the quantitative structure-activity relationship (QSAR) method. The structural features governing the reactivity of two classes of organic compounds toward e(aq)(-) were revealed, and the energy of the lowest unoccupied molecular orbital (E-LUMO), one-electron reduction potential (E-RED) and polarizability (alpha) were found to be the important molecular parameters in both two models. The built QSAR models provide robust predictive tools for estimating the removal of emerging pollutants using e(aq)(-) during wastewater treatment processes. Additionally, quantum chemical calculations were employed to probe into the mechanism and feasibility of the single electron transfer (SET) pathway in the e(aq)(-)-based reduction process. The thermodynamic investigation suggests that the compounds with electron-withdrawing groups tend to possess higher k(eaq-) and lower Gibbs free energy (Delta G(SET)) and Gibbs free energies of activation (Delta double dagger G(SET)(center dot)) than the ones with electron-donating groups, indicating the SET process occurs more readily. It is also found that the refractory halogenated compounds can achieve dehalogenation via the SET pathway. (C) 2018 Elsevier Ltd. All rights reserved.

Samples of gas and fine particulate matter (PM2.5) were collected in Dalian, China, a typical coastal city, to determine the concentrations, seasonal variations, influential factors, sources, and gas-PM2.5 partitioning of polybrominated Biphenyl ethers (PBDEs), novel brominated flame retardants (NBFRs), and dechlorane plus (DPs) in the ambient air. Annual average concentrations of Sigma 7PBDEs, BDE209, Sigma(6)NBFRs, and DPs were 4.40 +/- 2.93, 1460 +/- 2500, 7.81 +/- 6.85, and 0.15 +/- 0.14 pg/m(3) for the gas phase, and 2.68 +/- 1.64, 4291 +/- 4306, 13.6 +/- 23.4, and 0.31 +/- 0.22 pg/m(3) for the fine particle phase, respectively. BDE209 was the dominant congener, followed by HBB and BEH-TEBP, and seasonal variations in air concentrations were apparent for BFRs, especially those in the gas phase. Moreover, meteorological parameters and criteria air pollutants revealed significant positive correlations between temperature and less-brominated BFRs in the gas phase, and between PM2.5 and highly-brominated BFRs in the particle phase. This suggests that the presence of these compounds in ambient air may largely result from combustion-related processes. Furthermore, an analysis of the gas-PM2.5 partitioning of BFRs and DPs suggested that BFRs and DPs mostly attained equilibrium, except for some NBFRs. Due to the ban of commercial penta-, octa-, and deca-BDEs by the Stockholm Convention, emissions from historical use and combustion are becoming the important sources of PBDEs in China.

Nano ferrites (AFe(2)O(4), A = Zn, Co, Mn, Cu) were supported on the surface of gamma-Al2O3 support by hydrothermal synthesis to prepare a series of novel composite catalysts (AFe(2)O(4)/gamma-Al2O3) for catalytic ozonation for elimination of high concentration toluene at ambient temperature. The characterization results showed that the high-purity nano-AFe(2)O(4) particles were uniformly loaded on mesoporous gamma-Al2O3. Further, it was confirmed that among the several catalysts prepared, the amount of oxygen vacancies (O-vs), Lewis acid sites (LAS), and BrOnsted acid sites (BAS) of the ZnFe2O4/gamma-Al2O3 catalyst were the highest. This meant that the ZnFe2O4/gamma-Al2O3 catalyst had a strong adsorption capacity for toluene and ozone (O-3), and had a strong catalytic activity. When the temperature was 293 K and the space velocity was 1500 h(-1), the mol ratio of O-3 to toluene was 6, the degradation rate of toluene (600 mg m(-3)) can reach an optimum of 99.8%. The results of electron paramagnetic resonance (EPR) and Fourier infrared (FT-IR) proved superoxide radicals and hydroxyl radicals by catalytic ozonation. Moreover, the GC-MS analysis results indicated that the toluene degradation began with the oxidation of methyl groups on the benzene ring, eventually producing CO2 and H2O. After repeated experiments, the toluene degradation rate remained stable, and the residual content of O-3 in each litre of produced gas was less than 1 mg L-1, thereby indicating that the ZnFe2O4/gamma-Al2O3 catalyst had excellent reusability and showed great potential for the treatment of toluene waste gas.
