The cleavage of C-O linkages in aryl ethers in biomass-derived lignin compounds without hydrogenation of the aromatic rings is a major challenge for the production of sustainable mono-aromatics. Conventional strategies over the heterogeneous metal catalysts require the addition of homogeneous base additives causing environmental problems. Herein, we propose a heterogeneous Ru/C catalyst modified by Br atoms for the selective direct cleavage of C-O bonds in diphenyl ether without hydrogenation of aromatic rings reaching the yield of benzene and phenol as high as 90.3 % and increased selectivity to mono-aromatics (97.3 vs. 46.2 % for initial Ru) during depolymerization of lignin. Characterization of the catalyst indicates selective poisoning by Br of terrace sites over Ru nanoparticles, which are active in the hydrogenation of aromatic rings, while the defect sites on the edges and corners remain available and provide higher intrinsic activity in the C-O bond cleavage.

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.

Magnetic biopolymer hybrid nanoparticles have gained a lot of attention in the field of biomedical applications. Here we present the synthesis of hyaluronic acid (HA)-coated magnetic clusters of superparamagnetic nanoparticles. Firstly, the superparamagnetic magnetite nanoparticles coated with oleic acid were synthesized and characterized in terms of size, composition and magnetic properties. Secondly, magnetic nanoclusters were prepared and wrapped with HA grafted with an ethylene glycol-based copolymer. The resulting nanostructures and nanobeads were characterized using electron microscopy, dynamic light scattering, thermogravimetric analysis and magnetic measurements. The clustering of magnetite nanoparticles facilitates magnetic purification, separation, rapid attraction and controlled positioning by high field gradient micro-magnet arrays. In addition, clusters could be formed in the presence of a fluorescent drug model, which demonstrates the possibility of dual functionalization of our hybrid nanosystems: magnetic responsiveness and drug encapsulation.

Polybrominated diphenyl ethers (PBDEs), decabromodiphenyl ethane (DBDPE), 1,2-bis(2,4,6-tribromophenoxy)ethane (BTBPE), tetrabromobisphenol A (TBBPA), hexabromocyclododecane (HBCDD) and dechlorane plus (DP) were measured in sediments collected from three mangrove wetlands of the Pearl River Estuary (PRE) in South China. This study aims to investigate the distribution of these halogenated flame retardants (HFRs) and the correlations between HFRs and microbial community structure in mangrove sediments. Concentrations of PBDEs, DBDPE, BTBPE, TBBPA, HBCDD and DP in mangrove sediments ranged from 6.97 to 216.1, 3.70-26.0, 0.02-0.73, 0.02-37.5, 0.44-127.5 and 0.07-2.23 ng/g dry weight, respectively. Higher levels of PBDEs, BTBPE, HBCDD and DP were observed in sediments from Futian mangrove wetland of Shenzhen, the only nature reserve located in the downtown of China. The highest concentration of TBBPA found in mangrove sediments from Guangzhou was proximate to a ferry terminal and a dockyard where TBBPA is widely used in the coatings. PBDEs were the predominant HFRs in mangrove sediments, with an average contribution of 63.0%. Mangrove sediments from Guangzhou and Zhuhai showed an enrichment of (-)-alpha-HBCDD, (-)-beta-HBCDD and (-)-gamma-HBCDD. Concentrations of HFRs in mangrove sediments from Guangzhou increased significantly from 2012 to 2015, which was probably due to the establishment and rapid development of Nansha Free Trade Zone of Guangzhou. Redundancy analysis showed that HFRs may cause a shift of microbial community structure in mangrove sediments and the variations were significantly correlated with TBBPA, syn-DP and BTBPE.

A mild controllable oxidation method was developed to depolymerize the macromolecular aromatic clusters of NMH coal into water-soluble products (WSPs) without ring-open reaction. Hydrogen peroxide (H2O2) was employed to oxidize coal sample at 60 degrees C, and the effect of reaction time on coal conversion and oxidation products was studied. The results showed that H2O2 is able to break bridge bonds and side chains connected to aromatic clusters, while Car-Car bonds of arene keep unchanged at same conditions. After 10 h oxidation, the coal conversion is 83.4 wt% and the aromaticity of oxidation residue is 7.43%, indicating most of aromatics have transferred to WSPs. The aromatic ring distribution in WSP can reflect that of NMH coal to some extent, where 1ring, 2-ring and 3-ring compounds account for 58.4 mol%, 19.9 mol% and 21.7 mol%, respectively. Moreover, the pyrolysis of NMH coal and oxidation residue was conducted on an online pyrolysis-vacuum ultraviolet photoionization mass spectrometry, and the oxidation of several typical model compounds was also carried out to understand the oxidation mechanism. The results showed that the PhO-RPh bonds between aromatic clusters are most easily destroyed by H2O2. H2O2 oxidation degradation of coal are accompanied by generation of alkenes and decarboxylic reaction.

A method for using electronic structure calculations to predict the standard molar enthalpy of combustion for hydrocarbons is presented. In this approach, simple geometry optimizations can be used to accurately compute the enthalpy of combustion within 3% of the experimental value using Hartree-Fock, MP2, or virtually any functional in density functional theory calculations. This approach keeps the electronic structure calculations conceptually simple and computationally cheap, making this method accessible for a teaching lab with only minimal computational resources. This method is especially applicable to the bomb calorimeter experiment that typically appears in the physical chemistry teaching laboratory, and we provide an example of how our electronic structure calculations can be integrated into the laboratory curriculum.

We report the synthesis, characterization, and spectroscopic investigations of a new responsive-at-metal cyclometalated platinum(II) complex. With mild chemical oxidants and reductants, it was possible to obtain the same complex in three different oxidation states and each of these complexes was structurally characterized by single-crystal X-ray diffraction. We discovered that the platinum(II) complex displays strong solvatochromism in the solid state, which can be attributed to modulation of Pt…Pt interactions that results in switching between optical and photoluminescent states. Incorporating responsive-at-metal species as dynamic components in nanostructured materials might facilitate response amplification, sensing, actuation, or self-healing processes.

Bimetallic FeNi3 nanoparticles (NPs) enriched with Ni (FeNi3@Ni) have been used to perform the hydrodeoxygenation reaction (HDO) and cleavage of lignocellulose-derived products in solution using magnetic induction. The application of a high frequency magnetic field induces high temperatures at the surface of the NPs that drive the catalytic reaction. The activation of the C-O bond of several functional groups was studied. FeNi3@Ni NPs, which act both as catalysts and magnetic heating agents, catalyzed the total conversion of furfural and 5-hydroxymethyl furfural into respectively 2-methylfuran and 2,5-dimethylfuran under mild conditions (12 mol% catalyst, 3 bar H-2, 49 mT). The oligomerization of cyclopentanone, derived from furfural, was also achieved to yield C-10 and C-15 oligocyclopentyl products. Under the same conditions, diphenyl and benzyl phenyl ether, used as model molecules of polymeric lignin, were cleaved at 86% and 100% conversion respectively, to yield a mixture of hydrogenolysis and hydrogenated products. This is explained by the presence of Ni at the surface of the NP that favors the hydrogenation of the aromatic rings. The short reaction times and simplicity of the experimental set-up highlight the advantages of the application of magnetic heating for difficult transformations in solution, here the catalytic treatment of biomass-derived molecules.

Application In Synthesis of Diphenyl oxide. I found the field of Chemistry very interesting. Saw the article Direct Immersion-Solid-Phase Microextraction Coupled to Gas Chromatography-Mass Spectrometry and Response Surface Methodology for Nontarget Screening of (Semi-) Volatile Migrants from Food Contact Materials published in 2020.0, Reprint Addresses Nerin, C (corresponding author), Univ Zaragoza, Dept Analyt Chem, EINA, GUIA Grp,I3A, Zaragoza 50018, Spain.. The CAS is 101-84-8. Through research, I have a further understanding and discovery of Diphenyl oxide.

Toward a more rigorous inspection of food contact materials, the importance of sample preparation for nontarget screening should be addressed. Direct immersion-solid-phase microextraction coupled to gas chromatography mass spectrometry (DI-SPME-GC-MS) was optimized for nontarget screening of migrants in 3% acetic acid, 10% ethanol, and 95% ethanol food simulants by response surface methodology (RSM) in the present study. Optimum conditions were DVB/CAR/PDMS fiber, no pH adjustment for 10% and 95% ethanol simulant but pH adjustment to 7 for 3% acetic acid simulant, no salt addition, 5 min preincubation, 55 min extraction at 70 degrees C, and 8 min desorption at 250 degrees C. In addition, 9.5 times dilution of 95% ethanol samples prior to extraction was required. pH modification of 3% acetic acid samples was found to be critical for the extraction of amines. The proposed methodology was then evaluated by determining the limit of detection (LOD) as well as repeatability of 35 food contact materials-related substances. Except for those amines and diols which have a relatively high LOD, the LODs of the rest of the substances were 0.1-14.1 mu g/kg with a precision of 1.9-23.0% in 10% ethanol and were 0.1-20.2 mu g/kg with a precision of 2.5-19.6% in 3% acetic acid simulant. The LOD and precision in 95% ethanol simulant were 0.7-163.7 mu g/kg and 1.4-26.8%, respectively. The proposed method can be applied for an overall screening of migrants from these three simulants at even trace levels, though attention should be paid to some specific analytes, e.g., diols and amines, which could have a high LOD and toxicity.

Polybrominated diphenyl ethers (PBDEs) are extensively used as brominated flame retardants (BFRs) in different types of materials, which have been listed as Persistent Organic Pollutants (POPs) by the Stockholm Convention in 2009 and 2017. Due to their ubiquities in the environment and toxicities, PBDEs have posed great threat to both human health and ecosystems. The aim of this review is to offer a comprehensive understanding of the exposure pathways, levels and trends and associated health risks of PBDEs in human body in a global scale. We systematically reviewed and described the scientific data of PBDE researches worldwide from 2010 to March 2020, focusing on the following three areas: (1) sources and human external exposure pathways of PBDEs; (2) PBDE levels and trends in humans; (3) human data of PBDEs toxicity. Dietary intake and dust ingestion are dominant human exposure pathways. PBDEs were widely detected in human samples, especially in human serum and human milk. Data showed that PBDEs are generally declining in human samples worldwide as a result of their phasing out. Due to the common use of PBDEs, their levels in humans from the USA were generally higher than that in other countries. High concentrations of PBDEs have been detected in humans from PBDE production regions and e-waste recycling sites. BDE-47, -153 and -99 were proved to be the primary congeners in humans. Human toxicity data demonstrated that PBDEs have extensively endocrine disruption effects, developmental effects, and carcinogenic effects among different populations.
