The increasing risk of fossil fuels depletion due to surging energy demand has accelerated the search of alternative renewable sources. Lignin, one of the major components of lignocellulosic biomass, is the only abundant renewable natural resource for aromatic compounds. In this work, the effects of metals and process parameters were discussed via the catalytic hydrogenolysis of beta-O-4 lignin model compound, 2-phenethyl phenyl ether. The best results were obtained over Rh/Nb2O5 with an overall conversion of 99.3% and exceptional selectivity of 98.9% to aromatic products when the hydrogenolysis was carried out at 260 degrees C and 0.1 MPa H-2 for 4 h. The high efficiency is mainly attributed to the cooperation between Rh and NbOx at the perimeter sites, in which Rh particles are responsible for the dissociation of H-2 and NbOx for activating CeO bonds. With respect to depolymerize of ash wood lignin, the liquid products were mostly aromatics over Rh/Nb2O5 under 0.1 MPa H-2. The results achieved in this work provide a promising prospect towards valorization of lignin into production of valuable aromatic compounds under low hydrogen pressure.

A template free synthesis route was developed for the synthesis of hierarchical zeolite Beta from a natural layered aluminosilicate mineral kaolin. Detailed study on the crystallization of zeolite Beta established the optimized synthesis condition, and the synthesized hierarchical Beta zeolite was fully studied by XRD, IR, SEM, TEM, BET, NH3-TPD, Py-IR and NMR techniques. The characterization results reveal that the hierarchical Beta zeolite possesses good crystallinity, bimodal pore architecture, large surface area, big pore volume, high acid site concentration and excellent hydrothermal stability. An improved catalytic performance was achieved in hierarchical Beta zeolite for the esterification of acetic acid with benzyl alcohol, and the high activity and selectivity in this zeolite are mainly attributed to the presence of mesopores for accelerating the intraparticle diffusion rate of both reactant and product. This novel synthesis methodology provides a low-cost and environmentally-benign way for the preparation of hierarchical Beta zeolite, which could serve a sustainable platform of large-scale production of hierarchical zeolite for practical application.

In the present study, we report the synthesis of a series of copper(II) complexes with a wide range of ligands and their testing in the copper catalyzed Chan-Evans-Lam (CEL) coupling of aniline and phenylboronic acid. The efficiency of the coupling was directly connected with the ease of the reduction of Cu(II) to Cu(I) of the complexes. The most efficient catalyst was derived from 4-t-butyl-2,5-bis[(quinolinylimino)methyl]phenolate and two Cu(II) ions. Depending on the counter-anion nature and the concentration of the reaction mixture, the reaction can be directed to predominant C-N-bond formation. Forty-three derivatives of diphenylamine were prepared under the optimized conditions. The proposed mechanism of the catalysis was based on the reduction potential of a series of complexes, molecular weight measurements of the catalytic complex in MeOH and the kinetic studies of aniline and phenylboronic acid coupling. In addition, an H-1 NMR experiment in a sealed NMR tube, without external oxygen supply available, proved that no complete Cu(II) to Cu(I) conversion was observed under the condition, ruling out the usually accepted mechanism of the C-N coupling, which included the oxygenation of the intermediately formed Cu(I) complexes after the key step of C-N conversion had already been completed. Instead, a mechanism was proposed, involving an oxygen molecule coordinated to two copper ions in the key C-N bond formation without any detectable conversion of the Cu(II) complexes to Cu(I).

Development of new superparamagnetic materials with narrow size distribution is crucial for biomedical and environmental applications. Hence, we report the synthesis of narrow size distributed single grain MnFe(2)O(4)nanoparticles of average particle size 9 nm by solvothermal reflux method. Synthesized compound crystallized in face centered cubic spinel structure and is confirmed by X-ray diffraction profiles. Transmission electron micrograph shows narrow size distributed particles with an average particle size of 9 nm and is equal to crystallite diameter estimated from Scherrer equation. The spinel crystal structure is further confirmed by electron diffraction profiles, Fourier transformed infrared spectrum, and Raman spectrum at room temperature. Magnetic properties of the sample show superparamagnetic nature at room temperature with moderate saturated magnetization of 56.4 emug(-1). Magnetic heating properties of nanoparticles dispersion show the attainment of hyperthermia temperature (43 degrees C) in a short span of time of 1.6 min for 2 mg/mL and 2.6 min for 1 mg/mL concentrations. Estimated specific heat generation rate or specific power absorption rate, from temporal temperature plots, is 145.78 Wg(-1)and is useful for magnetic hyperthermia application in cancer therapy. Photocatalysis properties of sample show 96% of rhodamine B dye degradation in little less than 6 h under UV light irradiation and are useful for photocatalytic applications in wastewater treatment in industries.

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.

This study was designed to assess the effect of lactational polybrominated diphenyl ether (PBDE) exposure on early physical development of both healthy and fetal growth restriction (FGR) infants. Z scores of head circumference-for-age (ZHC), length-for-age (ZLEN), weight-for-age (ZWEI) and weight-for-length (ZWFL) were calculated according to the WHO Child Growth Standards. FGR infants had a higher PBDE exposure level and faster growth speed from 42 days to 6 months compared with healthy infants. Exposure of lower brominated BDEs (BDE28 similar to 154) and the sum of 18 BDE congeners (BDE28 similar to 209) negatively associated with ZHC [mean difference estimate (95 % CI): -0.71 (-1.22, -0.22) and -0.81 (-1.31, -0.33)] in FGR boys. Both BDE153 and BDE196 exposure had a significant correlation with ZLEN of boys in FGR group [mean difference estimate (95 % CI): -0.28 (-0.48, -0.07) and -0.52 (-0.91, -0.14)]. Each 10 ng/g lipid increase in the concentrations of BDE154 were respectively associated with 0.16 increase in ZWEI among boys in healthy group. No significant association was found in girls. Lactational PBDE exposure had effects on the early growth of both FGR and healthy infants. The encouragement of breastfeeding should therefore be considered in conjunction with PBDE contamination levels.

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.

Here, we report on a reproducible one-pot synthesis of high-quality and monodispersed CdS semiconducting nanocrystals (NCs) by mixing precursors cadmium acetate and elemental sulfur into the new solvent system of dibenzyl ether and oleylamine without using any extra reagent or precursor activator. The NCs (5 nm) exhibited a dominant band-edge emission with a good photoluminescence quantum yield of 13.76% without trap emission. The CdS NCs were characterized using UV?Vis and photoluminescence spectroscopy, electron microscopy, X-ray diffraction, and Fourier transform infrared spectroscopy. The practical efficiency of the synthesized NCs was proved by applying the synthesized CdS NCs as the tracer in the engineering of an immunosandwich biosensor to evaluate the cardiac troponin (cTn) marker for the diagnosis and monitoring of myocardial infarction (MI). The biosensor revealed significant analytical efficiency with the limit of detection of 2 ng L-1 and the linear dynamic range of 5?1000 ng L-1, which is lower than the existing cutoff values (13?20 ng L-1). Having capitalized on the anodic stripping voltammetry method, the screen-printed biosensor could efficiently detect the cTn markers. Therefore, the biosensor is proposed to be used in clinical settings for fast, sensitive, and accurate monitoring of cTn markers.

Despite the introduction of restrictive regulations in the USA and the European Union, polybrominated diphenyl ethers (PBDEs) are still found in various types of environmental and biological samples at significant concentration levels. The presence of these persistent organic pollutants in the environment raises important issues because of their negative impact on immunological and neurological systems, and on the hormonal balances in living organisms. From the analytical point of view, the final determination of PBDEs would entail substantial challenges, because it would necessitate conducting the pre-concentration of analytes, or sample clean up. The aim of the present study is to demonstrate the analytical application potential of developed dummy molecularly imprinted polymers as solid-phase extraction sorbents for the selective recognition of low-mass PBDEs. The 4,4′-dihydroxydiphenyl ether was employed as a dummy template of low-mass PBDEs. The developed types of the sorption materials were used in the sample preparation stage of the analytical procedure to determine the PBDE-47 and PBDE-99 levels in selected representatives of environmental samples reference materials of soil and bottom sediments. The recovery values of PBDE-47 and PBDE-99 from the studied solid samples ranged from 60% to 87%, depending on the applied DMIPs type.

C-H functionalization at the alpha-position of heterocycles has become a rapidly growing area of research. Herein, a cheap and efficient photochemical method was developed for the C-H functionalization of heterocycles. Phenylglyoxylic acid (PhCOCOOH) could behave as an alternative to metal-based catalysts and organic dyes and provided a very general and wide array of photochemical C-H alkylation, alkenylation, and alkynylation, as well as C-N bond forming reaction methodologies. This novel, mild, and metal-free protocol was successfully employed in the functionalization of a wide range of C-H bonds, utilizing not only O- or N-heterocycles, but also the less studied S-heterocycles.
