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.

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.

Methylammonium chloride as an interface modificator for planar-structure perovskite solar cells with a high open circuit voltage of 1.19V

Recently, the mixed-cation perovskites have been widely used in high-performance perovskite solar cells due to its excellent photoelectric properties. However, the mixed precursor-based method, particularly the complicated composition engineering, will cause phase transitional strain, low phase crystallinity and phase instability. Hence, interface modification engineering is very necessary to improve the phase crystallinity and stability, and then to optimize the performance of the photovoltaic devices. Herein, an interfacial engineering strategy is developed to enlarge the grain size and enhance the crystallinity of perovskite film through inserting a methylammonium chloride (MACl) layer between the SnO2 electron transport layer and perovskite layer. Therefore, the carrier extraction and transport are accelerated and the interfacial recombination is suppressed. Consequently, the optimal MACl-modified devices achieve a very high open circuit voltage of 1.19 V and a power conversion efficiency of 19.20% with the negligible hysteresis and enhanced stability in ambient condition, showing great superiority to the control devices without any modification.

I hope this article can help some friends in scientific research. I am very proud of our efforts over the past few months and hope to 50-30-6 help many people in the next few years. Recommanded Product: 2,6-Dichlorobenzoic acid.

Improving Hole-Conductor-Free Fully Printable Mesoscopic Perovskite Solar Cells’ Performance with Enhanced Open-Circuit Voltage via the Octyltrimethylammonium Chloride Additive

Hole-conductor-free fully printable mesoscopic perovskite solar cells (MPSCs) based on mp-TiO2/mp-ZrO2/carbon triple mesoscopic layers are competitive candidates among various rapidly developed PSCs for future photovoltaic applications due to the characteristics of low-cost, easy upscaling, and superior stability. However, the open-circuit voltage (V-OC) loss in printable MPSCs is relatively large compared to that in conventional PSCs, deteriorating the power conversion efficiency (PCE). Herein, the V-OC loss is reduced by the octyltrimethylammonium chloride (OTAC) additive. OTAC is found to upshift the Fermi level of TiO2 and passivate trap states in bulk MAPbI(3) perovskite, thus optimizing the energy-level alignment of the TiO2/perovskite heterojunction and suppressing nonradiative recombination in devices. As a result, MPSCs deliver the highest PCE of 16.53% with an improved V-OC of 1007 mV. The work demonstrates a facile strategy to reduce the V-OC loss in printable MPSCs by simultaneously optimizing the energy-level alignment and suppressing nonradiative recombination.

Thin-film nanocomposite membranes containing tannic acid-Fe3+ modified MoS2 nanosheets with enhanced nanofiltration performance

The development of thin-film nanocomposite (TFN) membranes for water treatment is of immense scientific interest. In this work, MoS2 nanosheets modified with tannic acid (TA)-Fe3+ coordination complexes were embedded within the polyamide (PA) layer to construct TFN nanofiltration (NF) membranes. The incorporation of modified MoS2 nanosheets into the PA matrix facilitates the formation of a bumpy surface with the appearance of scattered protuberances. Besides, the introduced covalent bonding between phenol groups and unreacted acid chloride groups during interfacial polymerization contributes to an enhanced crosslinking degree of the PA layer, simultaneously avoiding the formation of non-selective interfacial voids. The optimal TFN NF membrane with the addition of 0.01 wt% modified MoS2 nanosheets demonstrates 1.6-fold water permeance of the TFC membrane, along with increased salt rejection. The improved permeance of the TFN membrane is mainly due to the crumpled surface architecture with high roughness, which increases the permeable area for water transport. Overall, our study suggests that the employment of TA-MoS2 nanosheets for the construction of TFN membranes can be a promising method to develop high-performance NF membranes.

Development of a micro/nano composite sufper-hydrophobic silicon surface with nail-shaped texture/dual self-assembly monolayers and its wetting behavior

Micro-electromechanical systems often fail due to adhesion or wear, and preparing a stable super-hydrophobic surface is an effective approach to solve this problem. In this paper, the microscale square texture and nailshaped texture were designed and fabricated, and the nanoscale N-[3-(Trimethoxysilyl) propyl] ethylenediamine- Lauroyl chloride (DA-LA) dual self-assembly monolayers (SAMs) was developed to form a micro/nano composite structure. Meanwhile, micro/nanoscale surface morphology, chemical composition and surface free energy were characterized or calculated. Further, wettability and stability experiments were carried out. The results showed that the micro/nano composite structure achieves super-hydrophobicity and enhanced stability, and the maximum contact angle reaches 170.35 degrees. The nail-DA-LA surface with a 54.7 degrees overhang angle and rough sidewalls exhibited prominent super-hydrophobic stability, and the tribological experiments showed that the adhesion/friction reduced by 46.71% and 52.26%.

Inter-population differences in salinity tolerance of adult wild Sacramento splittail: osmoregulatory and metabolic responses to salinity

The Sacramento splittail (Pogonichthys macrolepidotus) is composed of two genetically distinct populations endemic to the San Francisco Estuary (SFE). The allopatric upstream spawning habitat of the Central Valley (CV) population connects with the sympatric rearing grounds via relatively low salinity waters, whereas the San Pablo (SP) population must pass through the relatively high-salinity Upper SFE to reach its allopatric downstream spawning habitat. We hypothesize that if migration through SFE salinities to SP spawning grounds is more challenging for adult CV than SP splittail, then salinity tolerance, osmoregulatory capacity, and metabolic responses to salinity will differ between populations. Osmoregulatory disturbances, assessed by measuring plasma osmolality and ions, muscle moisture and Na+-K+-ATPase activity after 168 to 336 h at 11 parts per thousand salinity, showed evidence for a more robust osmoregulatory capacity in adult SP relative to CV splittail. While both resting and maximum metabolic rates were elevated in SP splittail in response to increased salinity, CV splittail metabolic rates were unaffected by salinity. Further, the calculated difference between resting and maximum metabolic values, aerobic scope, did not differ significantly between populations. Therefore, improved osmoregulation came at a metabolic cost for SP splittail but was not associated with negative impacts on scope for aerobic metabolism. These results suggest that SP splittail may be physiologically adjusted to allow for migration through higher-salinity waters. The trends in interpopulation variation in osmoregulatory and metabolic responses to salinity exposures support our hypothesis of greater salinity-related challenges to adult CV than SP splittail migration and are consistent with our previous findings for juvenile splittail populations, further supporting our recommendation of population-specific management.

Entropy generation analysis of triple diffusive flow past a horizontal plate in porous medium

The combined natural heat and mass transfer, the so-called thermosolutal convective problem, has become an attractive field of research in many diversified areas. In this paper, for the first time, entropy analysis has been carried out for triple diffusive flow. A comprehensive model is developed for the entropy generation due to fluid friction, porous medium, heat, and mass transfer across a finite temperature and concentration difference in the chemical potential of two salts. In this model, a new term showing the entropy generation due to the coupling of concentration gradients of both salts is included. Furthermore, we have introduced a new mass Bejan number for the salts concentrations. The selected salts include sodium chloride and sucrose, which are added in water with different concentrations. The concentrations of both salts are assumed to be higher at the surface. The previously established dimensionless governing equations with Boussinesq approximation and Darcy law were solved numerically. The resulting velocity, temperature, and concentration gradients are employed in the entropy generation model. The impacts of the pertinent parameters and related dimensionless numbers on the dimensionless entropy generation rate, irreversibility ratio and Bejan numbers are examined for both assisting and opposing flows. It has been found that entropy generation rates are higher for assisting flows than opposing flows. At the same time, it is possible to reduce the entropy generation rate with a rise of the Darcy and Lewis numbers while the mass Bejan number increases with Lewis number. (C) 2020 Elsevier Ltd.

Effect of the food matrix on the capacity of flavor enhancers in intensifying salty taste

The effect of the flavor enhancers monoammonium glutamate (MAG), monosodium glutamate (MSG), disodium guanylate (GMP), and disodium inosinate (IMP) on intensifying salty taste in food matrices (shoestring potatoes, requeijao cheese, and beef burgers) with a reduction in the amount of sodium chloride (NaCl) present was evaluated. Experiments were conducted using a central composite rotational design with two variables: the concentrations of flavor enhancer and NaCl added in the food matrix. The effect of IMP was not significant (P > 0.05) on the intensity of salty taste in any of the matrices analyzed. GMP presented lower performance compared to MAG and MSG in intensifying the salty taste of the treatments, regardless of the reduction of NaCl. Compared to MSG and GMP, MAG showed greater efficiency in intensifying the salty taste in requeijao cheese and beef burger with a reduction of 25%, 50%, 75%, and 100% of NaCl. MSG presented higher efficiency compared to MAG and GMP when applied in shoestring potatoes for all reductions of NaCl tested (25%, 50%, and 75%). The ability of flavor enhancers to improve the salty taste depends on the effect of the flavor enhancer, the complexity of the food matrix, and the reduction of NaCl in foods. Practical Applications The complexity of the food matrix plays a significant role in the perception of salty taste in sodium-reduced products. In these products, sodium reduction may affect the taste enhancer’s effect of enhancing salty taste. Therefore, this study broadens the knowledge of the effects of flavor enhancers on different foods, as well as the ability to enhance salty taste in food matrices with NaCl reduction. Moreover, it provides information on how to reduce the sodium content in these matrices while maintaining the same perception of salty taste as a conventional matrix.

Enhanced Separation of Neodymium and Dysprosium by Nonaqueous Solvent Extraction from a Polyethylene Glycol 200 Phase Using the Neutral Extractant Cyanex 923

Neodymium and dysprosium can be efficiently separated by solvent extraction, using the neutral extractant Cyanex 923, if the conventional aqueous feed phase is largely replaced by the green polar organic solvent polyethylene glycol 200 (PEG 200). While pure aqueous and pure PEG 200 solutions in the presence of LiCl or HCl were not able to separate the two rare earth elements, high separation factors were observed when extraction was performed from PEG 200 chloride solutions with addition of small amounts of water. This addition of water bridges the gap between traditional hydrometallurgy and novel solvometallurgy and overcomes the challenges faced in both methods. The effect of different variables was investigated: water content, chloride concentration, type of chloride salt, Cyanex 923 concentration, scrubbing agent. A Job plot revealed the extraction stoichiometry is DyCl3 center dot 4L, where L is Cyanex 923. The McCabe-Thiele diagram for dysprosium extraction showed that complete extraction of this metal can be achieved by a 3-stage counter-current solvent extraction process, leaving neodymium behind in the raffinate. Finally, a conceptual flow sheet for the separation of neodymium and dysprosium including extraction, scrubbing, stripping, and regeneration steps was presented. The nonaqueous solvent extraction process presented in this paper can contribute to efficient recycling of rare earths from end-of-life neodymium-iron-boron (NdFeB) magnets.
