Does the salt really matter? Impact of the counterion upon ECL signal

The incorporation of counterions into a variety of substances to control a number of their physiochemical properties is vital within a range of fields. Electrochemiluminescence (ECL) based sensors have grown in popularity in recent years with their employment observed across analytical and bioanalytical applications. ECL is typically concerned with the core electroactive functionality of the species of interest, with structural similarities commonly employed to determine the likelihood of a species ECL capability. However, to date no consideration has been given to the impact of different counterions toward an analytes ECL mechanism. Here we report for the first time how a simple alternation to a co-reactants counterion can significantly impact upon its recorded ECL response. Utilizing the tropane alkaloid scopolamine and its hydrobromide and hydrochloride salt forms, we have seen through interrogation with the traditional ruthenium luminophore, that replacement of the bromide anion for the chloride anion can reduce the electroactivity of the species. Direct comparison between the hydrobromide and hydrochloride salt forms relived differences in respect of their emission potentials and intensities. The impact of the salt form upon the ECL response has here been investigated, in respect to predicted concentrations. Results demonstrated how vastly different concentrations were obtained dependent upon the salt form present within the sample and that which was used to produce the calibration curve. The impact of this discovery will be of interest to the electrochemiluminescent and electroanalytical communities, and in particular forensic practitioners where electrochemical and ECL based sensors are of increasing interest. Ultimately the application of an ECL sensor within an analytical environment relies upon its accuracy and hence a thorough understanding of the phenomenon observed will only stand to widen the acceptance of ECL within the wider analytical community and increase its potential future applications.

The ability of layered double hydroxides for nitrate absorption and desorption in crop and fallow rotation

BACKGROUND AND OBJECTIVES: This study aims down to evaluate the ability of chloride magnesium- aluminium- layered double hydroxides (4:1) for nitrate adsorption from the soil solution in successive cropping periods. METHODS: The study was conducted under long-term cropping periods, including first crop): bell pepper; second crop: mentheae; third crop: cherry tomato; and fort h crop: wheat), absorption of soil mineral nitrate in fallow periods and nitrate absorption from plants by layered double hydroxides. The effect of layered double hydroxides on qualitative and quantitative characteristics of plants was also studied. FINDINGS: Results indicated that layered double hydroxides were able to induce long-term nitrate exchange in crop and fallow sequences. Layered double hydroxides can adsorb soil excessive nitrates in cropping periods and reduce nitrate concentration in the soil solution. Compared to control, the treatment with 16 gram layered double hydroxide/kilogram soil could reduce nitrate concentration in the soil solution by 95%. During two-week fallow periods, the amount of nitrates mineralized in the soil solution was increased, but layered double hydroxides treatments could adsorb them well and maintained the N-nitrate concentration in the soil solution at a low level. Additionally, Results indicated that application of 2, 4, 8 and 16 gram layered double hydroxides/kilogram soil led to 34%, 44%, 58% and 69% reduction in N-nitrate concentration of soil leachates, respectively, compared to control. By increasing nitrogen availability, layered double hydroxides improved the quantitative and qualitative properties of plants. Application of 2, 4, 8 and 16 gram layered double hydroxides/ kilogram soil increased the plant height (cherry tomato) by 14%, 26%, 50% and 80%, respectively. CONCLUSION: It is concluded that the layered double hydroxides has a potential to be used as a long-term nitrate exchanger to control the movement of nitrate in soil, and thereby reduce risks of nitrate leaching in crop production in sensible areas.

Porcine Circovirus Type 3 Enters Into PK15 Cells Through Clathrin- and Dynamin-2-Mediated Endocytosis in a Rab5/Rab7 and pH-Dependent Fashion

Porcine circovirus type 3 (PCV3) invades multiple tissues and organs of pigs of different ages and are widely spread throughout pig farms, emerging as an important viral pathogen that can potentially damage the pig industry worldwide. Since PCV3 is a newly discovered virus, many aspects of its life cycle remain unknown. Porcine kidney epithelial cells are important host targets for PCV3. Here, we used systematic approaches to dissect the molecular mechanisms underlying the cell entry and intracellular trafficking of PCV3 in PK15 cells, a cell line of porcine kidney epithelial origin. A large number of PCV3 viral particles were found to colocalize with clathrin but not caveolin-1 after entry, and PCV3 infection was significantly decreased when treated with chlorpromazine, dynasore, knockdown of clathrin heavy chain expression via RNA interference, or overexpression of a dominant-negative mutant of EPS15 in PCV3-infected cells. After internalization, the viral particles were further observed to colocalize with Rab5 and Rab7, and knockdown of both expression by RNA interference significantly inhibited PCV3 replication. We also found that PCV3 infection was impeded by ammonium chloride treatment, which indicated the requirement of an acidic environment for viral entry. Taken together, our findings demonstrate that PCV3 enters PK15 cells through a clathrin- and dynamin-2-mediated endocytic pathway, which requires early and late endosomal trafficking, as well as an acidic environment, providing an insightful theoretical basis for further understanding the PCV3 life cycle and its pathogenesis.

Correlating scalants characteristic and air bubbling rate in submerged vacuum membrane distillation: A fouling control strategy

The feasibility of aeration for membrane scaling mitigation in submerged vacuum membrane distillation (S-VMD) system was evaluated. The effect of aeration rate in both intermittent and continuous modes were investigated. The flux decline rate due to fouling was reduced significantly with air bubbling. In the absence of aeration, larger salt crystals containing sodium chloride (NaCl) and magnesium sulphate (MgSO4) were deposited on the membrane. Continuous air bubbling at 30 LPM provides sufficient surface shear with noticeable reduction of sealants on the membrane surface. However, continuous bubbling at higher flow rate (60 LPM) caused rapid nucleation and smaller crystals on membrane that inferior the bubble scouring effect. Based on the theoretical analysis of hydrodynamic forces induced by the bubble flow, the net shear force generated by the bubbling at 60 LPM with velocity of 0.2 m/s (bubble size of 250-400 mu m) is not effective to remove particle that is smaller than 1.09 mu m. Continuous aeration at 30 LPM showed better cleaning efficiency and had almost constant specific energy consumption over long term operation. These results indicated that air bubbling is a feasible and effective method for alleviating membrane scaling in S-VMD system.

Photon correlation spectroscopy in the fish salting process

The current study experimentally investigates the innovative photon correlation spectroscopy method application in fish salting process. The method is based on the Rayleigh scattering of light by a substance. The experiment aims to study the mass transfer laws, as well as technological and practical aspects of the fish salting process in brine without circulation. The paper focused on spatio-temporal dependence of the salt diffusion coefficients in the fish-brine system and their correlation with temperature, indicating that at a temperature close to 8 degrees C a diffusion-osmosis equilibrium occurs between the brine and the muscle tissue of fish. The salt diffusion rate was estimated, confirming the validity of the Crean’s frontal theory of salt mass transfer in muscle tissue of fish. Based on the Stokes-Einstein equation, it was shown that the dynamic viscosity of fish tissue fluid could be determined by changing the diffusion coefficient and the diffusing particles size. Practical applications Fish salting is an important preservation method in many countries. The present work seeks to investigate the salting of herring, as it is prone to ripening during this process. Excessive sodium chloride consumption is known to have a negative effect on humans. At the same time, the salt content in the product is interrelated with its preservation effect. In this regard, it is necessary to accurately calculate the specified salt concentration in the finished product for the optimal shelf life. Improvement of this process requires a better understanding of the mass-transfer mechanisms using modern investigation methods. Research focuses on spatio-temporal salt distribution in fish muscle tissue to arrive at clear conclusions, which can facilitate the improved production of salted fish and can be widely used in the food industry for processing and preserving fish or fish products.

Electrochemical immunosensor based on self-assembled gold nanorods for label-free and sensitive determination of Staphylococcus aureus

An electrochemical immunosensor based on self-assembled gold nanorods on glassy carbon electrode was developed for label-free and sensitive detection of Staphylococcus aureus (S. aureus). The gold nanorods were firstly assembled on the electrode surface by using poly-(diallyldimethylammonium chloride) (PDDA) and poly(styrenesulfonate) (PSS) as the linkers, followed by the functionlization of anti -S. aureus antibodies. The immobilized antibodies on self-assembled gold nanorods could efficiently capture S. aureus to the modified electrode by the specific immune reaction, which clearly blocked the electron transfer of electrochemical probes on the electrode surface due to the resistance of S. aureus. Atomic force microscopy and electrochemical impedance spectroscopy were used to verify the stepwise assembly of the immunosensor fabrication. The immunosensor could detect S. aureus in a linear range from 1.8 x 10(3) to 1.8 x 10(7) CFU mL(-1) with a low detection limit of 2.4 x 10(2) CFU mL(-1). Furthermore, the designed electrochemical immunosensor was successfully used to determine S. aureus in milk samples with acceptable results. The proposed immunosensor could be further expanded to sensitive detect other pathogens with the addition of specific antibodies.

Controlled Growth of Large Grains in CH3NH3PbI3 Perovskite Films Mediated by an Intermediate Liquid Phase without an Antisolvent for Efficient Solar Cells

High-quality crystalline large grains with uniform morphologies of the perovskite films are particularly important for achieving stable, high-performance perovskite solar cells. Herein, an effective strategy to control the growth of large grains in the CH3NH3PbI3 perovskite films is demonstrated by modifying the perovskite film deposition process through forming an intermediate CH3NH3PbI3 center dot methylammonium chloride (MACl)center dot xCH(3)NH(2) liquid phase induced by CH3NH2 gas treatment in combination with a MACl additive without an antisolvent. By tuning the incorporation of the MACl additive to the perovskite precursor solution, this intermediate liquid phase enables the well-controlled growth of large grains up to 3 mu m, highly uniform morphology, and higher crystallinity in the final CH3NH3PbI3 perovskite films. The high-quality CH3NH3PbI3 film derived from the CH3NH3PbI3 center dot MACl center dot xCH(3)NH(2) phase leads to enhanced carrier lifetime and reduced charge-trap density and nonradiative recombination of the perovskite films. In addition, the defect healing and reduced grain boundaries also greatly improve the environmental stability in ambient air. The perovskite solar cells made via the CH3NH3PbI3 center dot MACl center dot xCH(3)NH(2) phase exhibit high power conversion efficiency of 18.4%, much higher than that of the perovskite solar cells made without MACl (15.8%).

Studies on the self-aggregation, interfacial and thermodynamic properties of a surface active imidazolium-based ionic liquid in aqueous solution: Effects of salt and temperature

The influence of four sodium salts (NaCl, NaBr, Na2SO4, and Na3PO4) on the self-aggregation, interfacial, and thermodynamic properties of a surface active ionic liquid (1-hexadecyl-3-methylimidazolium chloride, C(16)MImCl) has been explored in aqueous solutions by conductometry, tensiometry, spectrofluorimetry, isothermal titration calorimetry and dynamic light scattering (DLS). Analyses of the critical micellar concentration (cmc) values indicate that the anions of the added salts promote the self-aggregation of C(16)MImCl in the order: Cl- < Br- < PO43-< SO42-. Dehydration of imidazolium head groups, in general, governs the process of micellization of aqueous C(16)MImCl in presence of the investigated salts within the investigated temperature range (298.15-318.15 K), while the melting of iceberg takes the leading role below 303.15 K for the C(16)MImCl-Na3PO4 system. The results indicate that addition of salt leads to a greater spontaneity of micellization, and that exothermicity prevails in these systems. Differential effect of the salts on the interfacial properties of C(16)MeImCl has been interpreted on the basis of the coupled influence of the electrostatic charge neutralization of surfactants at the interface, and the van der Wa-als repulsion of surfactant tails and electrostatic repulsion of surfactant head groups. C(16)MeImCl has been predicted to form spherical micelles in presence of varying amounts of NaCl, Na2SO4 and Na3PO4, while there occurs probably a transition in the micellar geometry from spherical to non-spherical shape when added NaBr concentration exceeds 0.01 mol.kg(-1). Fluorescence studies demonstrate that a combined quenching mechanism is operative for the quenching of pyrene fluorescence in the investigated C(16)MImCl-salt systems. Micellar aggregation numbers obtained from Steady State Fluorescence Quenching method have always been found be somewhat smaller than those estimated from Time Resolved Fluorescence Quenching method. The order of instability of the C(16)MImCl-micelles ascertained from Zeta potential measurements conform to what has been inferred from the cmc values. The hydrodynamic diameters of C(16)MImCl-micelles, obtained from DLS studies, have been found to increase with increasing salinity of the solutions. (C) 2020 Published by Elsevier B.V.

Electrocatalytic activity of metal-doped SnO2 for the decomposition of aqueous contaminants: Ta-SnO2 vs. Sb-SnO2

Sb-doped SnO2 (ATO) is one of the most widely used electrocatalyst anodes for the oxidation of water and wastewater. This study synthesizes Ta(V)-doped SnO2 (TTO) electrocatalysts as alternatives to ATO and systematically examines their electrocatalytic activity for the decomposition of organic substrates in various electrolyte solutions. The as-synthesized ITO exhibits the highest activity for the decomposition of phenol, N,N’-dimethyl-4-nitrosoaniline, and rhodamine-B at a Ta doping level of similar to 1%. The optimized TTO exhibits a higher activity for the decomposition of phenol than ATO in a chloride solution and a lower activity than ATO in a sulfate solution. Electron paramagnetic resonance analysis reveals that a relatively larger production of reactive oxygen species is achieved with ATO, whereas a larger production of reactive chlorine species is obtained with TTO. In the durability tests, both electrodes favor an alkaline condition (pH 12.8) over acidic and neutral conditions (pH 1.5 and 6.2, respectively), and Ta-SnO2 is less stable than Sh-SnO2 over the full pH range. Additionally, solid-state and electrochemical surface characterizations are carried out.
