Magnetic core-shell nanostructures offer a viable solution for tunable magnetism via nanoscale exchange interactions in a single-component unit. A typical synthetic approach for monodisperse bimagnetic ferrite core-shell nanostructures employs the seed-mediated growth method using the heating-up process. Understanding magnetic core-shell interface formation and their interactions is crucial; however, the magnetical persistence of the pristine core component during the heating-up process is unclear. Here, we elucidate the enhancement mechanism of magnetic anisotropy when the hard-soft core-shell nanostructures are formed with the ultrathin shell layer. The heating-up effect on the core component exhibits the coordination change of ligand chemisorption with surface metal ions, which leads to a substantial increase in surface anisotropy due to enhanced spin-orbit couplings. We further demonstrate that the selection of metal precursors and surfactants for additional shell layer formation is important. The kinetic of the shell formation rate by their thermolysis and atomic-scale surface etching by the surfactant led to the disordering of surface spins on the core parts. Our observations provide the underlying mechanism of high anisotropic magnetism while bimagnetic ferrite core-shell interface formation and the voyage of synthetic procedures for the additional shell layer are critical to an outcoming magnetism.

Computed Properties of C14H14O. I found the field of Science & Technology – Other Topics; Materials Science; Physics very interesting. Saw the article Adjusting the Neel relaxation time of Fe3O4/ZnxCo1-xFe2O4 core/shell nanoparticles for optimal heat generation in magnetic hyperthermia published in 2021, Reprint Addresses De Biasi, E; Winkler, EL (corresponding author), Consejo Nacl Invest Cient & Tecn, Ctr Atom Bariloche, Inst Nanociencia & Nanotecnol CNEA, RA-8400 San Carlos De Bariloche, Argentina.; De Biasi, E; Winkler, EL (corresponding author), Univ Nacl Cuyo, Inst Balseiro, Mendoza, Argentina..

In this work it is shown a precise way to optimize the heat generation in high viscosity magnetic colloids, by adjusting the Neel relaxation time in core/shell bimagnetic nanoparticles, for magnetic fluid hyperthermia (MFH) applications. To pursue this goal, Fe3O4/ZnxCo1-xFe2O4 core/shell nanoparticles were synthesized with 8.5 nm mean core diameter, encapsulated in a shell of similar to 1.1 nm of thickness, where the Zn atomic ratio (Zn/(Zn + Co) at%) changes from 33 to 68 at%. The magnetic measurements are consistent with a rigid interface coupling between the core and shell phases, where the effective magnetic anisotropy systematically decreases when the Zn concentration increases, without a significant change of the saturation magnetization. Experiments of MFH of 0.1 wt% of these particles dispersed in water, in Dulbecco modified Eagles minimal essential medium, and a high viscosity butter oil, result in a large specific loss power (SLP), up to 150 W g(-1), when the experiments are performed at 571 kHz and 200 Oe. The SLP was optimized adjusting the shell composition, showing a maximum for intermediate Zn concentration. This study shows a way to maximize the heat generation in viscous media like cytosol, for those biomedical applications that require smaller particle sizes.

Hollow Beta zeolite with hierarchical meso/microporous has been synthesized via one-step hydrothermal method by using a designed cationic surfactant of N-2-p-N-2 as soft-template. The structure-directing ability of N-2-p-N-2 was studied by the DFT calculations. The hollow Beta zeolite with a hierarchical structure was characterized by a combination of X-ray diffraction, Fourier transform infrared spectroscopy, nitrogen adsorption-desorption isotherms, scanning electron microscopy and transmission electron microscopy. The structural characterization suggested that the positively charged quaternary ammonium group can interact with the anionic aluminosilicate species to induce the formation of Beta zeolites. The hollow zeolites possess the large inner cavity and hierarchical structure, which can significantly reduce diffusion limitations and facilitate accessibility of the active sites. FTIR spectra of 2,6-di-tertbutylpyridine results indicated that the hollow Beta zeolite with hierarchical structure provided increased external surface acid sites and exhibited superior catalytic property in the benzylation of benzyl alcohol with mesitylene. Such hollow zeolite with hierarchical structure has great potential in catalysis involving large molecules.

I found the field of Science & Technology – Other Topics very interesting. Saw the article Co-exposure risks of pesticides residues and bacterial contamination in fresh fruits and vegetables under smallholder horticultural production systems in Tanzania published in 2020.0. Category: ethers-buliding-blocks, Reprint Addresses Kapeleka, JA (corresponding author), Nelson Mandela African Inst Sci & Technol NM AIST, Arusha, Tanzania.; Kapeleka, JA (corresponding author), Trop Pesticides Res Inst TPRI, Arusha, Tanzania..

This study was carried out to investigate the risks of simultaneous exposure to pesticide residues and bacteria contaminants in locally produced fresh vegetables and vegetables in Tanzania. A total of 613 samples were analyzed for pesticide residues, out of which 250 were also analyzed for bacterial contamination. Overall, 47.5% had pesticide residues, 74.2% exceeded Maximum Residue Levels (MRLs). Organophosphorus (95.2%), organochlorines (24.0%), pyrethroids (17.3%), and carbamates (9.2%) residues dominated. MRL values were mostly exceeded in tomatoes, onions, watermelons, cucumbers, Chinese cabbage, and sweet paper. Tetramethrin (0.0329-1.3733 mg/kg), pirimiphos-methyl (0.0003-1.4093 mg/kg), permethrin (0.0009-2.4537 mg/kg), endosulfan (beta) (0.0008-2.3416 mg/kg), carbaryl (0.0215-1.5068 mg/kg), profenofos (0.0176-2.1377 mg/kg), chlorpyrifos (0.0004-1.2549 mg/kg) and dieldrin (0.0011-0.5271 mg/kg) exceeded MRLs. The prevalence of bacteria contamination was high (63.2%). Enterobacter (55.6%) Pseudomonas aeruginosa (32.4%), E. coli (28.2%), Citrobacter (26.8%), Klebsiella oxytoca (14.8%), and Salmonella (7.7%) were isolated. Furthermore, 46.4% tested positive for both pesticide residues and bacterial contaminants. Vegetables from farms (60.7%) contained more dual contaminants than market-based vegetables (41.8%). This may have resulted from excessive pesticide use and unhygienic handling of fresh fruits and vegetables at production level. Binary logistic regression showed that fresh fruits and vegetables with pesticide residues were 2.231 times more likely to have bacteria contaminants (OR: 2.231; 95% CI: 0.501, 8.802). The contamination levels of pesticide residues and bacterial contaminants could be perceived as a serious problem as most fresh fruits and vegetables recorded values of pesticide residues far above the MRLs with pathogenic bacteria isolated in higher proportions. MRLs was higher in most vegetables consumed raw or semi-cooked such as watermelons, carrots, cucumber, tomatoes, onion and sweet paper. There is an urgent need to develop pesticide monitoring and surveillance systems at farmer level, educating farmers and promoting the use of greener pesticides to mitigate the health effects of pesticides and bacterial contaminants.

Obtaining bulk materials ordered at the nanoscale using nanoparticles as building blocks is a new challenge for scientists and is of primary interest in some research areas. In this study, we developed a simple one-pot route towards nanostructured hybrid materials based on uranium oxide through a non-hydrolytic condensation process under mild solvothermal conditions (T = 160 degrees C) using ditopic organic linkers as structuring agents. The obtained materials present a sand rose morphology composed of agglomerated nanometric sheets with a lamellar substructure. Nanometric sheets are composed of inorganic fringes consisting of a studtite phase [(UO2)O-2(H2O)(2)]center dot 2H(2)O that alternates with organic fringes formed by the structuring organic linker. A multiparametric study based on SAXS experiments and TEM analyses has highlighted the control of structural parameters by varying some synthesis conditions. The interlamellar distances are tunable from 1.60 nm to 1.94 nm through the length of the structuring linker and the inter-sheet distance from 1.85 nm to 2.10 nm through synthesis temperature. This efficient one-pot route appears to be very promising for the production of tunable multiscale nanostructured hybrid materials and can be implemented in many research areas, paving the way for various applications.

The Name is Benzyl ether. Through research, I have a further understanding and discovery of 103-50-4.

Mesoporous TiO2(B) whisker was firstly applied as a support for synthesizing the novel sulfated solid superacid (SO42-/TiO2(B)). According to NH3-TPD, TG and Py-IR characterization results, it was found that the similar amount of sulfate group on TiO2(B) and anatase showed significantly different acid characteristics and catalytic performances. The total acid amount of SO42-/TiO2(B) was about 1.8 times as anatase-supported sulfated solid superacid (SO42-/Anatase). Simultaneously, the SO42-/TiO2(B) possessed higher percentage of Bronsted acid and more weak-medium acid strength than SO42-/Anatase. These acidic properties endowed SO42-/TiO2(B) with the increased esterification reaction rate and decreased alkylation byproduct selectivity compared with that of SO42-/Anatase. Structure-performance analysis exhibited that there were more bridged bidentate sulfate groups coordinated to the TiO2(B) in SO42-/TiO2(B), which could induce more Ti cations than that of the chelating one. This was the key factor to be responsible for the unique acid characteristics of SO42-/TiO2(B). The present work provides a novel solid superacid and might open a strategy to mediate the acid characteristic for sulfated solid superacid.

Introduction: The prevalence of type 2 diabetes (T2D) is increasing worldwide. Recent studies have suggested that environmental factors, such as exposure to brominated flame retardants (BFRs), could play a role in the epidemic of T2D. The aim of this study was to analyze the association between the dietary exposure to BFRs (Hexabromocyclododecane (HBCD) and Polybromodiphenylether (PBDE)) and T2D risk in the E3N prospective cohort of French women. Research design and methods: Overall, 71,415 women followed for 19 years were included in the study. We performed Cox regression models to analyze the association between dietary exposure to BFRs and T2D risk. Results: Overall 71,415 women were included and 3667 (5.13%) developed a T2D during follow-up. The mean dietary exposure to HBCD and to PBDE was 0.22 ng/kg body weight (BW)/day and 1.21 ng/kg bw/day, respectively. There was a positive linear association between dietary exposure to HBCD and T2D risk starting from the 2nd quintile group (HR: 1.18; 95% CI: 1.06-1.30) to the 5th quintile group (HR: 1.47; 95% CI: 1.29-1.67) when compared to the 1st quintile group. We also found positive although non-linear associations between dietary exposure to PBDE and T2D risk, with an increased HR only for the 2nd and 4th vs. 1st quintile groups (HR: 1.12; 95% CI: 1.02-1.24, and HR: 1.20; 95% CI: 1.08-1.34, respectively). Conclusion: The findings suggest an association between dietary exposure to BFRs and T2D risk, highlighting the importance of further investigating this association the long-term health effects of endocrine disruptors in the general population. Additional studies are needed to reproduce these findings in other populations and clarify the underlying biological mechanisms.

The sluggish kinetics of the oxygen reduction reaction (ORR) on electrocatalysts represents a major obstacle in the development of fuel cell technology. A tremendous amount of work has reported the increasing ORR activity for catalysts. Nevertheless, when applied to practical Membrane Electrode Assembly (MEA, an assembled stack of a proton exchange membrane fuel cell) configuration, the high-performance catalysts on the rotating disk electrode (RDE) may not display the same high activity as in the lab-scale tests. This led us to reexamine the ORR evaluation based on the RDE technique. With the development of high active electrocatalysts, it may become significant to determine the reasonable kinetic current at a conventional fixed potential approaching the limited current by using the Koutecky-Levich (K-L) technique on RDE for the evaluation of ORR activity. Here we describe such a challenging situation and systematically discuss the proper kinetic region when comparing the ORR activity with the unsuitable potential or Pt loading based on the K-L technique. Furthermore, the rational benchmarking guidelines are given for the evaluation of the ORR electrocatalysts.

Human nails have been increasingly used as a biomarker for human exposure to persistent organic pollutants (POPs). In the present study, the fingernails of e-waste-dismantling workers from Longtang town, Qingyuan city, rural residents from Shijiao town, Qingyuan city, and urban residents from Guangzhou city, respectively, were collected from South China to monitor the human burdens of polybrominated diphenyl ether (PBDEs) and polychlorinated biphenyl (PCBs). The median concentrations of Sigma PBDEs in the nails of the e-waste-dismantling workers, and urban and rural residents were 412, 129, and 82.1 ng g(-1), respectively, and the median concentrations of Sigma(20)PCBs were 108, 8.4, and 22.1 ng g(-1), respectively. The levels of PCBs and PBDEs in the nails of e-waste-dismantling workers were significantly higher as compared to those for urban and rural residents (p< 0.05), implying the continuous and greater exposure to these chemicals in the e-waste recycling areas. BDE 209 (92-98%) was the major congener of PBDEs and CB 52 (26-51%) was the main congener of PCB in nail samples. However, no significant gender difference was observed for PBDE and PCB levels in nails from all three investigated areas, and no significant correlation was found between their levels and the age of the participants. The enantiomer fractions (EFs) of CBs 95 and 132 indicated that the external sources (e.g.dust and/or air) were the primary sources for CBs 95 and 132 in human nails from the e-waste area, while the contribution from the internal sources (e.g.serum) could be in a small percentage. The results of this study indicate that human nails can be used as a proper indicator of human exposure to PCBs and PBDEs, and further studies are needed by a comprehensive investigation of the relationships between the PCB and PBDE levels in the nails and serum and/or other internal tissues.
