While infants are developing, they are easily affected by toxic chemicals existing in their environments, such as semi-volatile organic compounds (SVOCs): phthalates, polycyclic aromatic hydrocarbons (PAHs), polybrominated diphenyl ethers (PBDEs), and organophosphate esters (OPEs). However, the specific living environment of infants, including increased plastic products and foam floor mats, may increase the presence of these chemicals, In this study, 68 air, dust, and window film samples were collected from homes, with 3- to 6-month-old infant occupants, to analyze phthalates, PAHs, PBDEs, and OPEs. High detection rates and concentrations suggest that these SVOCs are widespread in infant environments and are associated with cooking methods, smoking habits, the period of time after decoration, and room floors. The partitioning behavior of SVOCs indicates that the logarithms of the dust/gas-phase air partition coefficient (logK(D)) and the window film/gas-phase air partition coefficient (logK(F)) in homes are not at an equilibrium state when the logarithm of the octanol/air partition coefficient (logK(OA)) is less than 8 or greater than 11, Considering the 3 exposure routes, ingestion and dermal absorption have become the main routes of infant exposure to phthalates and OPEs, and ingestion and inhalation have become the dominant routes of exposure to PAHs and PBDEs. The total carcinogenic risk of SVOCs, which have carcinogenic toxicities, via ingestion and dermal absorption for infants in homes exceeds the acceptable value, suggesting that the current levels of these SVOCs in homes might pose a risk to infant health.

Khawaji, M; Chadwick, D in [Khawaji, Motaz; Chadwick, David] Imperial Coll London, Dept Chem Engn, London SW7 2AZ, England published Selective catalytic oxidation over Au-Pd/titanate nanotubes and the influence of the catalyst preparation method on the activity in 2019, Cited 41. The Name is Benzyl ether. Through research, I have a further understanding and discovery of 103-50-4.

The dependence of the selective oxidation catalytic activity of Au-Pd supported on titanate nanotubes on the catalyst preparation method has been investigated. The most active Au-Pd/Ti-NT catalyst for the selective oxidation of benzyl alcohol is shown to be that prepared using colloidal synthesis and immobilization with PVA as a stabilizer, which has markedly superior catalytic activity compared to catalysts prepared by deposition-precipitation, adsorption, and dry impregnation methods. Au-Pd NPs stabilized by graphene oxide sheets and immobilized on Ti-NT has also been studied and while not optimum shows promising catalytic activity. The superior catalytic activity of the catalysts prepared by colloidal synthesis is attributed to the high metal dispersion on the external surfaces of Ti-NT, the narrow particle size distribution, and the high degree of Au-Pd alloying. This work also demonstrates that in the adsorption method of preparation using HAuCl4.3H(2)O and PdCl2 precursors, the uptake of Pd ions in solution by Ti-NT is proportional to the sodium content in Ti-NT, which implies that Na is involved in an ion-exchange reaction with Pd ions.

A green, cost-effective and facile steam-assisted crystallization (SAC) strategy was developed to synthesize core-shell-structured zeolite composites with different frameworks between the core and shell. Chemical incompatibility from different structures has been circumvented by dip-coating Silicalite-1 seeds and an in situ transformation process. Beta@Silicalite-1 zeolites with a nanoscale polycrystal Silicalite-1 shell wrapped around the monocrystal Beta core was synthesized. The crystallization process and synthetic parameters, such as the composition of the core, crystallization temperature and gel composition of the seed solution, were investigated. The results revealed the importance of stability of the core and the crystallization rate of the Silicalite-1 shell. Interestingly, a trace amount of aluminum in the core zeolite could help resist corrosion during crystallization. Further investigation on alkylation and etherification reactions over Beta@Silicalite-1 demonstrated the advantage in selectivity control toward self-etherification versus alkylation.

The challenge of coating organic photovoltaics (OPV) from green solvents is to achieve the required nanostructured interpenetrating network of donor and acceptor domains based on a rational choice of solvent approach as opposed to the usual trial-and-error methods. We demonstrate here that we can achieve a bicontinuous interpenetrating network with nanoscale phase separation for the chosen donor-acceptor material system poly[2,3-bis-(3-octyloxyphenyl)quinoxaline-5,8-diyl-alt-thiophene-2,5-diyl]:phenyl-C-61 butyric acid methyl ester (TQ1:PC61BM) when processing from green solvent ink formulations. This structure is achieved by first calculating the Hansen solubility parameters (HSP) of the donor and acceptor materials, followed by careful choice of solvents with selective relative solubilities for the two materials based on the desired order of precipitation necessary for forming a nanostructured interdigitated network morphology. We found that the relative distances in Hansen space (R-a) between TQ1 and the primary solvent, on the one hand, and PC61BM and the primary solvent, on the other hand, could be correlated to the donor-acceptor morphology for the formulations based on the solvents d-limonene, anisole, and 2-methyl anisole, as well as the halogenated reference solvent o-dichlorobenzene. This nanostructured blend film morphology was characterised with scanning transmission X-ray microscopy (STXM) and transmission electron microscopy (TEM), and the film surface composition was analysed by near edge X-ray absorption fine structure (NEXAFS) spectroscopy. Hansen solubility theory, based on solution thermodynamics, has been used and we propose an HSP-based method that is a general platform for the rational design of ink formulations for solution-based organic electronics, in particular facilitating the green solvent transition of organic photovoltaics. Our results show that the bulk heterojunction morphology for a donor-acceptor system processed from customised solvent mixtures can be predicted by the HSP-based method with good reliability.

The catalytic regioselective C-H silylation of a wide range of alkoxy-substituted benzene derivatives with primary hydrosilane was achieved by the use of scorpionate-supported calcium benzyl complex [(Tp(Ad,iPr))Ca(p-CH2C6H4Me)(THP)] (1) (Tp(Ad,iPr) = hydrotris(3-adamantyl-5-isopropylpyrazolyl)borate, THP = tetrahydropyran) as the precatalyst. This protocol offers an atom-efficient and straightforward method for the synthesis of a variety of silyl-substituted aromatic ether derivatives without a hydrogen acceptor and free of transition metal. Calcium anisyl complexes [(Tp(Ad,iPr))Ca(o-MeO-m-Br-C6H3)] (5) and [(Tp(Ad,iPr))Ca(o-Me-OCH2C6H4)] (6), proposed as the catalytic reaction intermediates, were isolated and structurally characterized.

The MFI zeolites with nanosheet assemblies morphology were prepared by a seed-assisted strategy using specially designed bolaform surfactant [C6H13-N+ (CH3)(2)-C6H12-N+ (CH3)(2)-(CH2)(12)-O-(p-C6H4)(2)-O-(CH2)(12)-N+(CH3)(2)-C6H12-N+(CH3)(2)-C6H13] [Br-](4) (C6-12-diphe) as a structure-directing agent. The MFI zeolite nanosheet assemblies were composed of MFI nanosheets with randomly organized structure, exhibiting a narrow mesopore distribution. By tuning the Si/AI ratios of MFI zeolite nanosheet assemblies from 60 to 10, the morphology of resultant zeolites changed from nanosheet stacks to house-of-cards-like structures, and to nanosponges. In addition, the porosity and Bronsted acid/Lewis acid ratio exhibited a parabola-type dependence on the Si/Al ratios of obtained zeolites, indicating that meso-/microporosity and acidity of MFI nanosheet assemblies can be systematically tailored by changing the constituents of zeolites. Catalytic performance of MFI zeolite nanosheet assemblies was investigated in the benzylation of benzyl alcohol with mesitylene. The results revealed that MFI zeolite nanosheet assemblies exhibited extraordinary catalytic activity compared to conventional ZSM-5 zeolite. The conversion of benzyl alcohol and selectivity (1,3,5-trimethyl-2-benzylbenzene vs dibenzyl ether) of zeolite catalysts were linearly dependent on the 81-misted acid/Lewis acid ratio, and they exhibited a parabola-type dependence on the S-ext/S-BET, indicating that a balance between acidity and porosity of zeolites can be realized to modulate the catalytic properties of MFI zeolite nanosheet assemblies guided by C6-12-diphe.

The development of an efficient solid catalyst for Friedel-Crafts (FC) reactions is of great importance to organic synthetic chemistry. Herein, we reported the hafnium-doped mesoporous silica catalyst Hf/SBA-15 and its first use for Friedel-Crafts alkylation reactions. Catalysts with different Si/Hf ratios were prepared and characterized, among which Hf/SBA-15(20) (Si/Hf = 20:1) was the most active catalyst, offering up to 99.1% benzylated product under mild reaction conditions. The influences of reaction conditions on the product were systematically investigated and compared. Pyridine-IR characterization of the catalyst showed that Lewis acid formed the primary active sites for the Friedel-Crafts alkylation reaction. X-ray photoelectron spectroscopy (XPS) characterization revealed that the electron shift from the Hf center to the silica framework resulted in a more active Lewis metal center for FC reactions. Moreover, the catalyst was successfully applied to the alkylation reaction with different alcohols and aromatic compounds. Finally, the Hf/SBA-15(20) catalyst also showed good recyclability in the recycling runs, demonstrating its high potential of being used for large scale FC reactions in the industry.

Various optical clearing methods have emerged as powerful tools for deep biological imaging. Organic solvent-based clearing methods, such as three-dimensional imaging of solvent-cleared organs (3DISCO), present the advantages of high clearing efficiency and size reduction for panoptic imaging of large samples such as whole organs and even whole bodies. However, 3DISCO results in a rapid quenching of endogenous fluorescence, which has impeded its application. Here, we propose an advanced method named FDISCO to overcome this limitation. FDISCO can effectively preserve the fluorescence of various fluorescent probes and can achieve a long storage time of months while retaining potent clearing capability. We used FDISCO for high-resolution imaging and reconstruction of neuronal and vascular networks. Moreover, FDISCO is compatible with labeling by multiple viruses and enables fine visualization of neurons with weak fluorescence labeling in the whole brain. FDISCO represents an effective alternative to the three-dimensional mapping of whole organs and can be extensively used in biomedical studies.
