Provision of safe drinking water, devoid of aetiologies, is an all-time challenge due to the usage of unsafe chemicals in most of the water treatment processes. The main objective of the present paper is to evaluate the use of Moringa oleifera (MO) as a natural coagulant in coagulation/flocculation (C/F) followed by the ultrafiltration (UF) of Final Effluent Treatment Plant wastewater treatment which can also be employed as an alternative to the present conventional methods of treatment. process efficiency was evaluated in terms of chemical oxygen demand (COD), biochemical oxygen demand (BOD), turbidity, total hardness, alkalinity, ammoniacal nitrogen, and zeta potential along with permeability and fouling behaviour of the membrane. A significant improvement in both the physical and chemical characteristics of the effluent quality is showing a clearer colour and a greater reduction in BOD (89.74%) and COD (63.80%) values, while pH was in the acceptable range for effluent disposal. The results indicate a lower membrane fouling rate (49%), an increase in permeate flow, and better quality of the permeate, proving that the C/F-UF treatment is an effective and efficient technique for wastewater treatment. Eventually, the treated wastewater obtained with this process generates better quality water and preserves the aquatic ecosystem.

Copper-zinc-tin sulfide (Cu 2 ZnSnS 4 or CZTS), a quaternary compound, behaves as an intrinsic p-type semiconductor, making it an attractive, cost-effective and environmentally-friendly alternative as an absorber layer in photovoltaic cells. In this study, we deposited CZTS onto ITO conductive glass substrates using a single-step co-electrodeposition technique known as Cu-Zn-Sn-S (Co-Ed). The deposition process occurred at room temperature in an aqueous citrate electrolyte bath containing copper (II), zinc (II), tin (II), and sulfur. The deposition process was assisted by cyclic voltammetry to study the influence of cycle numbers, in particular 5, 10 and 15, on the structural and optical characteristics of sulfidation-free films. Scans were carried out at a rate of 20 mV/s in the potential range from −1.6 to 0 eV. CZTS thin films were characterized using X-ray diffraction (XRD) and UV–visible spectroscopy (UV–vis). The XRD results indicate the formation of CZTS kesterite, as evidenced by characteristic peaks. Likewise, optical analysis reveals an optical gap energy closely aligned with the optimum gap for the CZTS absorber layer (1.5 eV), making it suitable for photovoltaic applications.

This study investigates the application of edible insect protein–chitosan (IP/CS) complex coacervates, derived from T. molitor, A. domesticus, and L. migratoria proteins combined with low-, medium-, or high-molecular-weight chitosans, as stabilizers in Pickering emulsions aimed at enhancing emulsion stability and improving the retention of bioactive compounds. The underlying hypothesis posits that IP/CS can function as effective stabilizing systems in Pickering emulsions, providing high overall stability, low susceptibility to destabilization, and efficient encapsulation of lipophilic bioactives. Experimental results showed that IP/CS-based Pickering emulsions achieved high β-sitosterol retention, ranging from 56 % to 91 %. Emulsion stability was primarily attributed to electrostatic interactions and hydrogen bonding within the coacervates. In addition, an effective stabilization mechanism was identified, involving the physical integration of oil droplets into the IP/CS matrix, which contributed to reduced flocculation. Fourier-transform infrared (FTIR) spectroscopy and rheological analysis confirmed the presence of hydrogen bonding and indicated a viscous character of the emulsions, while ζ-potential measurements revealed surface charge properties that further supported emulsion stabilization. These findings demonstrate the role of intermolecular interactions in maintaining the integrity of oil-in-water (O/W) Pickering emulsions stabilized by IP/CS complexes.

We hypothesized that balancing the content of exogenous amino acids, especially lysine, to reduce protein content in swine diets could reduce nitrogen(N) pollution associated with animal husbandry. Two experiments(45 d each experiment) were performed on weaned piglets(Duroc x Landrace x Yorkshire,28 d of age) to test this and to determine the optimal lysine to crude protein(Lys:CP) ratio in diet. In Exp. 1,12 piglets(6 replicates [n = 6]) were fed diets containing different levels of CP(17% and 20%) but the same level of Lys, Increased CP content resulted in significant increases(P < 0.05) of average daily gain(ADG), average daily feed intake(ADFI), and body weight(BW);but did not affect the feed to gain ratio. In Exp. 2,24 piglets(8 replicates [n = 8]) were fed 1 of 3 diets as follows: 1) 20% CP with a regular Lys:CP ratio(6.23%, control);2) 17% CP with a reduced Lys:CP ratio(6.14%, LL);or 3) 17% CP with a standard Lys:CP ratio(7.32%, SL). The ADG, final BW, serum concentrations of growth hormone and insulin-like growth factor-1, villus height in the jejunum, and villus height to crypt depth ratio were the lowest in piglets fed LL diet, whereas blood urea N concentration was the lowest and the value of lipase activity was the highest in the piglets fed SL diet. The SL diet did not affect growth performance,intestinal morphology, or serum hormone concentrations, indicating that reduced dietary N with a high Lys:CP ratio can efficiently reduce dietary N excretion without negatively affecting weaned piglets.

Zn ₂ SnO ₄ /SnO ₂ and ZnO/SnO ₂ biphasic nanocatalysts have been synthesized by a facile solvothermal method using ethylene glycol (EG) as solvent in three different ways maintaining the pH of the solution at either 3 or 9 followed by calcination at 700 °C. The nanocatalysts are characterized by different techniques to investigate their structure, composition, morphology and optical properties. The XRD results indicate the formation of pristine biphasic composites. The UV-absorbance and photoluminescence spectra confirms the formation of biphasic composites as well as presence of large number of defects in the prepared nanocatalysts. The biphasic nanocomposites possess better photocatalytic activity towards the degradation of Acid Red-183 (AR-183) dye than pristine SnO ₂ and ZnO nanoparticles. This is mainly due to better charge separation, minimal recombination rate of charge carriers and defect-riched structures of nanocatalysts. © 2019

The stable functionality of networked systems is a hallmark of their natural ability to coordinate between their multiple interacting components. Yet, real world networks often appear random and highly irregular, raising the question of what are the naturally emerging organizing principles of complex system stability. The answer is encoded within the system's stability matrix - the Jacobian - but is hard to retrieve, due to the scale and diversity of the relevant systems, their broad parameter space, and their nonlinear interaction dynamics. Here, we introduce the dynamic Jacobian ensemble, which allows us to systematically investigate the fixed-point dynamics of a range of relevant network-based models. Within this ensemble, we find that complex systems exhibit discrete stability classes. These range from asymptotically unstable, where stability is unattainable, to sensitive, in which stability abides within a bounded range of the system's parameters. Alongside these two classes, we uncover a third asymptotically stable class, in which a sufficiently large and heterogeneous network acquires a guaranteed stability, independent of its microscopic parameters and of external perturbation. Hence, in this ensemble, two of the most ubiquitous characteristics of real-world networks - scale and heterogeneity - emerge as natural organizing principles to ensure fixed-point stability in the face of changing environmental conditions. © 2020, CC BY.

In the coal-based combustion and gasification processes, the mineral matter contained in the coal (predominantly oxides), is left as an incombustible residue, termed ash. Commonly, ash deposits are formed on the heat absorbing surfaces of the exposed equipment of the combustion/gasification processes. These deposits lead to the occurrence of slagging or fouling and. consequently, reduced process efficiency. The ash fusion temperatures (AFTs) signify the temperature range over which the ash deposits are formed on the heat absorbing surfaces of the process equipment. Thus, for designing and operating the coal-based processes, it is important to have mathematical models predicting accurately the four types of AFTs namely initial deformation temperature, softening temperature, hemispherical temperature, and flow temperature. Several linear/nonlinear models with varying prediction accuracies and complexities are available for the AFT prediction. Their principal drawback is their applicability to the coals originating from a limited number of geographical regions. Accordingly, this study presents computational intelligenee (CI) based nonlinear models to predict the four AFTs using the oxide composition of the coal ash as the model input. The CI methods used in the modeling are genetic programming (GP), artificial neural networks, and support vector regression. The no table features of this study are that the models with a better AFT prediction and generalization performanee, a wider application potential, and reduced complexity, have been developed. Among the Ci-based models, GP and MLP based models have yielded overall improved performanee in predicting all four AFTs.
