Rayleigh scattering and disorder-induced mixing of polarizations in amorphous solids at the nanoscale: 1-octyl-3-methylimidazolium chloride glass

Acousticlike excitations in topologically disordered media at mesocale/nanoscale present anomalous features with respect to the Debye’s theory. The so-called Rayleigh scattering manifests in a strong increase of the attenuation of the acousticlike excitations and a softening of the phase velocity with respect to its continuum limit value. Mean field models developed in the random media theory framework can successfully predict the occurrence, at the proper length scale, of Rayleigh scattering. The overall attenuation in the Rayleigh region is, however, underestimated. In the framework of random media theory we developed an analytical model, which permits a quantitative description of the acousticlike excitations in topological glasses in the whole first pseudo-Brillouin zone. The underestimation of the Rayleigh scattering is avoided and, importantly, the model allows to account also for the polarization properties of the acousticlike excitations. In a three-dimensional medium an acoustic wave is characterized by its phase velocity, intensity, and polarization. Rayleigh scattering emphasizes how the topological disorder affects the first two properties. The topological disorder is, however, expected to influence also the third one. In common with the Rayleigh scattering, hallmarks possibly related to the mixing of polarizations have been traced in different classes of amorphous solids at nanoscale. The quantitative theoretical approach developed permits to demonstrate how the mixing of polarizations generates a distinctive feature in the dynamic structure factor of amorphous solids. The modeling capability of the proposed mean field theory is tested on glassy 1-octyl-3-methylimidazolium chloride, whose spatial distribution of the elastic moduli is well assessed and can be experimentally characterized. Contrast between theoretical and experimental features for the selected glass reveals an excellent agreement. The mean field approach we present retains a certain degree of generality and can be possibly extended to different stochastic media or different wave fields.

Determination of microplastic content in seafood: An integrated approach combined with the determination of elemental contaminants

A method for the determination of microplastic (MP) content in seafood is proposed based on the selective digestion of seafood without the degradation of MP. A simple approach was developed using diluted acid with microwave-assisted wet digestion. The following parameters were evaluated: nitric acid concentration (0.5 to 14.4 mol L-1), digestion temperature (180 to 220 degrees C), irradiation program holding time (10 to 30 min), MP particle size (0.3 to 5 mm), and the seafood mass (0.5 to 2 g). To develop a reliable method for the determination of MP amount, up to 2 g of an in natura seafood sample were spiked with a known amount of MP (100 mg of mixed MP). Suitable conditions were obtained using 1 mol L-1 HNO3 at 200 degrees C (10 min holding time). Digests were filtered and the plastic content was gravimetrically determined. The heating program was 20 min, which represents a significant reduction in the time normally reported in the literature for MP analysis (from few hours up to 3 days). The proposed method allowed gravimetric determination of eight plastic types (polyethylene terephthalate, polystyrene, expanded polystyrene, polypropylene, high and low density polyethylene, polycarbonate and polyvinyl chloride) with particle size >= 0.3 mm. Up to 2 g of an in natura seafood sample (shark species, acoupa weakfish, tuna fish, trahira, and pink shrimp) were efficiently digested, which opened the possibility of using the proposed digestion method for determining elemental contaminants (Al, As, Ca, Cd, Co, Cr, Cu, Fe, Hg, La, Mg, Mn, Mo, Ni, Pb, and Zn). Thus, as the main feature of the proposed digestion method is the possibility of determining MP and elemental contaminants using the same digestion protocol, saves time and reagents and provides accurate and precise information about different classes of marine pollutants (MP and elemental contaminants).

Cu(I)-Catalyzed Heterogeneous Multicomponent Polymerizations of Alkynes, Sulfonyl Azides, and NH4Cl

Nitrogen-containing polymers are a group of fascinating materials, which are usually prepared from nitrogencontaining organic monomers produced from NH3 gas or aqueous solution of ammonia. The direct utilization of safe, clean, convenient, and inexpensive inorganic NH4Cl salt as a nitrogen source for the construction of functional polymers is highly desired but challenging. Multicomponent polymerizations, with their strong designability, structural diversity, high efficiency, simple procedure, and environmental benefit, have been proven to be powerful tools to efficiently convert simple monomers to complex polymer materials. In this work, Cu(I)-catalyzed multicomponent polymerizations of alkynes, sulfonyl azides, and NH4Cl are developed, utilizing simple inorganic NH4Cl salt to serve as a monomer for the preparation of functional poly(sulfonyl amidine)s. The heterogeneous polymerization goes smoothly at room temperature in CH2Cl2/tetrahydrofuran, which is also applicable to a range of different monomer structures, affording seven poly(sulfonyl amidine)s with high yields (up to 96%) and high molecular weights (up to 47,100 g/mol). Unique functionalities such as photophysical properties and metal ion detection can be introduced to the poly(sulfonyl amidine)s either from monomer structures or the in situ generated product structures, rendering them as selective and sensitive fluorescence sensors for Ru3+. This multicomponent polymerization showed high synthetic efficiency with environmental and economic benefit, which has opened up a feasible synthetic method of using inorganic NH4Cl salt instead of organic amines, isocyanates, isocyanides, or nitriles to construct nitrogen-containing polymers, demonstrating a promising synthetic approach for the synthesis of advanced functional polymer materials.

Empowering Australian insecticide resistance research with genetic information: the road ahead

Insecticides are important for chemical control of arthropod pests in agricultural systems but select for resistance as an adaptive trait. Identifying the genetic mechanism(s) underpinning resistance can facilitate development of genetic markers, which can be used in monitoring programs. Moreover, understanding of genetic mechanisms in a broader population genetic context can be used to infer the origins of resistance, predict the dynamics of resistance evolution and evaluate the efficacy of different management strategies. Transitioning genetic information successfully into practical solutions requires overcoming two major hurdles. Firstly, genetic mechanisms must be identified to develop genetic markers. Secondly, routine use of genetic markers is required to build substantial spatio-temporal data on the distribution and frequency of resistance alleles. In this study, we demonstrate large knowledge gaps on the genetic mechanisms of insecticide resistances in Australia using eight established arthropod pests important to the grains industry: Bemisia tabaci (silverleaf whitefly), Frankliniella occidentalis (western flower thrips), Halotydeus destructor (redlegged earth mite), Helicoverpa armigera (cotton bollworm), Myzus persicae (green peach aphid), Plutella xylostella (diamondback moth), Tetranychus urticae (two-spotted spider mite) and Thrips tabaci (onion thrips). Many resistances have not been characterised at the genetic level in most pests, even for chemical MoA groups with a long history of use in Australia. Moreover, monitoring of resistance is spatio-temporally patchy, which precludes examination of long-term trends or predictive modelling. We suggest that leveraging cumulative global knowledge of resistances to develop a priori candidate genes, and incorporation of genomic approaches, can help overcome the hurdles of embracing genetic information in resistance management. We highlight the recently invasive Spodoptera frugiperda (fall armyworm) as a case study where genetic markers and genomic approaches should prove useful in rapidly assessing the risk of this species to the Australian grains industry and other agricultural commodities. The uptake of genetic information into management can only occur once its benefit to empower insecticide resistance research is fully realised. Ultimately, the road ahead requires amalgamation of multifaceted data (genes, environment and spatio-temporal replication) to better understand and predict the dynamics of resistance evolution.

Urinary concentrations of phthalate metabolites in pregnant women living near Chapala Lake, Jalisco, Mexico

Phthalates are esters of phthalic acid used in a broad array of consumer products and food contact surfaces. Phthalates are known endocrine disruptors and oxidant stressors, and exposure has been associated with premature birth, asthma, obesity, insulin resistance and endometriosis. Though many industrializing countries are known to manufacture phthalates, few studies have examined exposure to phthalates in this context, let alone in rural communities where phthalate-containing products are widely used. We evaluated the presence of 16 phthalate metabolites in third trimester pregnant women in three rural communities near the largest lake in Mexico, Lake Chapala, by liquid chromatography coupled to tandem mass spectrometry in 90 urine samples. Phthalate metabolites were found in all samples, where the highest concentration was 1830 ng/mL in mono-ethyl phthalate (mEP), and it was present in 98.9% of all samples. These findings suggest the need for further research on the effect of endocrine disrupting chemicals in developing countries, and public health guidance on opportunities for prevention.

Spin-coated Cu2ZnSnS4 solar cells: A study on the transformation from ink to film

In this paper, we study the DMSO/thiourea/chloride salt system for synthesis of pure-sulfide Cu 2 ZnSnS 4 (CZTS) thin-film solar cells under ambient conditions. We map out the ink constituents and determine the effect of mixing time and filtering. The thermal behavior of the ink is analyzed, and we find that more than 90% of the solvent has evaporated at 250. C. However, chloride and sulfoxide species are released continually until 500. C, suggesting the advantage of a higher pre-annealing temperature, which is also commonly observed in the spin-coating routines in literature. Another advantage of a higher pre- annealing temperature is that the worm-like pattern in the spin-coated film can be avoided. We hypothesize that this pattern forms as a result of hydrodynamics within the film as it dries, and it causes micro-inhomogeneities in film morphology. Devices were completed in order to finally evaluate the effect of varying thermal exposure during pre- annealing. Contrary to the previous observations, a lower pre-annealing temperature of 250. C results in the best device efficiency of 4.65%, which to the best of our knowledge is the highest efficiency obtained for a puresulfide kesterite made with DMSO. Lower thermal exposure during pre-annealing results in larger grains and a thicker MoS 2 layer at the CZTS/Mo interface. Devices completed at higher pre-annealing temperatures display the existence of either a Cu-S secondary phase or an incomplete sulfurization with smaller grains and a fine-grain layer at the back interface.

Selective Electrochemical Sensing of NADH and NAD(+) Using Graphene/Tungstate Nanocomposite Modified Electrode

Reduced form of beta-nicotinamide adenine dinucleotide (NADH) and its oxidized form (NAD(+)) are the main cofactors involved in more than 300 dehydrogenase reactions. NAD(+) is one of the important oxidizing agent for the oxidation of alcohol, aldehyde and ketones. Similarly, NADH has been used for the treatment of Alzheimer and Parkinson’s diseases. Herein, we have reported synthesis of graphene flakes by electrochemical exfoliation of graphite in sodium tungstate solution. It was found that tungstate (WO42-) and hydroxyl (OH-) ions were intercalated into graphite layers and enabled the production of graphene flakes. As-obtained graphene flakes were characterized by UV-Visible (UV-Vis), Fourier transform infrared (FT-IR), Raman, Field emission scanning electron microscopy (FE-SEM), Energy dispersive X-ray (EDX) and High-resolution transmission electron microscopies (HR-TEM). FT-IR, Raman and EDX analysis were confirmed that tungstate (WO42-) ions were present on the surface of graphene flakes. Moreover, graphene-WO42- (Gr-W) dispersion was prepared by probe-sonication to form a thin-film on the surface of glassy carbon electrode (Gr-W/GCE). Interestingly, Gr-W modified GCE reduced the overpotentials of NADH oxidation and NAD(+) reduction. This new senor was also showed linear responses for NADH and NAD(+) from 10-270 mu M and 100-500 mu M, respectively. Furthermore, the selectivity of the Gr-W/GCE was tested in the presence of L-tyrosine, L-isoleucine, L-alanine, glutathione, dopamine (DA), ascorbic acid (AA), uric acid (UA), oxalic acid (OA), glucose, hydrogen peroxide (H2O2)(,) acetaminophen (PA), potassium chloride (KCl) and sodium chloride (NaCl). It was found that selective detection of both NADH and NAD(+) could be achieved by using Gr-W/GCE. Finally, the real application of the sensor was demonstrated by accurately detecting spiked NADH concentrations in human blood serum. The recovery analysis was also confirmed that Gr-W/GCE could be useful to detect NADH in biological samples.

Microwave-assisted preparation of flower-like C-60/BiOBr with significantly enhanced visible-light photocatalytic performance

The surface properties of photocatalysts significantly affect the photocatalytic activity. For this reason, it is desirable to boost the photocatalytic activity of BiOBr photocatalysts via surface modification. In this demonstration, C-60 was used to decorate BiOBr by a microwave hydrothermal method. The flower-like C-60/BiOBr photocatalysts, assembled by nanosheets, were carefully examined with structural, optical, and compositional analyses. The results confirm that C-60 and BiOBr have been combined together. Because of the existence of synergistic interaction, C-60/BiOBr has a higher specific surface area, higher partition and migration of photo induced carriers, higher surface hydroxyl and O-center dot(2)- levels, higher oxygen vacancies (OVs) concentration on the catalytic surface. The formation of O-center dot(2)- was significantly enhanced, confirmed by nitrotetrazolium blue chloride (NBT) measurements. O-center dot(2)- can be effectively formed by two channels. Based on the photodestruction result of Rhodamine B (RhB), the photocatalytic activity of C-60/BiOBr composites was significantly boosted. In light of all the observations and the high electron affinity of C-60, separation of photoinduced carriers and a formation mechanism of active free radicals is proposed.
