This process involves the use of photocatalysts through light activation, typically semiconductors such as titanium dioxide (TiO2) or polyoxometalates (POM) to generate reactive species capable of degrading organic pollutants.

This work evaluated photodegradation performance of methyl orange (MO) and malachite green (MG) dyes using hybrid-polyoxometalate (HPOM) photocatalyst. Fourier Transform Infrared Spectroscopy (FTIR) identified the characteristic band at 3463.66 cm–1 (O-H) and 997.74 cm–1 (W-O). Scanning Electron Microscopy (SEM) revealed the presence of rod-like and granular structures in HPOM, representing silver acetate and sodium tungstate. X-ray diffraction (XRD) confirmed characteristic peak of Keggin structure, revealing high crystallinity of HPOM. UV-assisted photodegradation was evaluated on different parameters (initial dye concentration, photocatalyst dosage and pH), highlighting HPOM’s better affinity for degrading cationic dye. The optimum photodegradation conditions for MG and MO dyes were 20 ppm dye concentration, 100 mg photocatalyst dosage, and pH 7 and 8, respectively. The kinetic data was fitted with the Langmuir Hinshelwood kinetic model, indicating pseudo-first-order kinetics.

The corrosion leads to materials loss and damage; hence it is important to prohibit such corrosion damage using an eco-friendly corrosion inhibitor. In the current work, a polymer composite-based corrosion inhibitor was prepared using polyvinylpyrrolidone (PVP) and 2-Acrylamido-2-methylpropane sulfonic acid (AMPS). The PVP copolymer undergoes polymerization with the AMPS having several interconnected uniformly sized pores and produces a PVP–AMPS composite with rod-like microstructure. The effect of concentration, time, and temperature on corrosion inhibition efficiency (IE) of PVP–AMPS composite was studied for copper and brass in hydrochloric acid (HCl) solution. The IE increases with concentration and decreases with time and temperature. A change in cathodic and anodic Tafel slopes with the concentration of PVP–AMPS inhibitors was observed. The increase in IE with concentration was attributed to the solubility of PVP–AMPS composite in HCl. However, the decrease in IR with time and temperature was due to the desorption of PVP–AMPS composite from the surface of copper and brass and also due to the exothermic reactions at higher temperature. A few peaks in FTIR spectra at 3000–3100 cm−1 were missing, which is due to the stretching vibration of H–C during the crosslinking polymerization. Further, the absence of the O–H peak indicated that the polymerization process removed the water molecule. The best correlation coefficient (R2) for the Langmuir adsorption mechanism was achieved. A negative Gibbs free energy (ΔG) envisages the spontaneity of the adsorption process. However, the | ΔG| for adsorption was less than 20 kJmol−1 confirming the process as physisorption. A shift in anodic and cathodic branches in the presence of the PVP–AMPS inhibitor indicated a mixed-type inhibitor behavior.","PeriodicalId":8097,"journal":{"name":"Applied Science and Engineering Progress","volume":"115 15","pages":""},"PeriodicalIF":0.0,"publicationDate":"2024-07-26","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"141802102","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

This causes individuals to spend more time indoors. The health, comfort, and well-being of building occupants are directly impacted by indoor air quality, which is a significant issue. The main objective of this study was to investigate the optimal conditions for the treatment of gaseous formaldehyde using TiO2 – Nylon 6 electrospun composite membrane via photocatalytic oxidation. Response surface methodology (RSM) model with the Box-Behnken Design (BBD) was applied for experimental design and statistical analysis. Three factors (catalyst dosage, initial formaldehyde concentration, and gas flow rate) affecting the removal efficiency were studied. Three sets of experiments were conducted to compare the formaldehyde removal efficiencies of the following processes; the adsorption process, the photolysis process, and the photocatalytic oxidation process. From the results, it is obvious that the photocatalytic oxidation process yielded the highest removal efficiency (83.43%) as compared to the other two processes. The mechanism of the formaldehyde photocatalytic oxidation process can be described using the simplified Langmuir-Hinshelwood equation. The reaction follows a pseudo-first order reaction, with a rate constant of 0.0058 min–1. The optimal conditions were found to be at 80.0%w/w catalyst dosage, 7.0 ppm initial formaldehyde concentration, and 1.5 L/min gas flow rate which resulted in an 84.54% removal efficiency after 420 minutes of treatment period. Thus, the application use of the TiO2 – Nylon 6 electrospun composite membrane equipped with the UV light source could be a promising alternative technology for indoor air treatment.","PeriodicalId":8097,"journal":{"name":"Applied Science and Engineering Progress","volume":"106 10","pages":""},"PeriodicalIF":0.0,"publicationDate":"2024-07-19","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"141820617","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The current work focused on combining electrocoagulation, ion-exchange, and ultrasonication treatment approaches for the simultaneous removal of copper, nickel, and zinc ions from water. The removal of the three studied ions was significantly enhanced by increasing the power density (4–10 mA/cm2) and NaCl salt concentration (0.5–1.5 g/L) at a natural solution pH. The simultaneous removal of these metal ions at 4 mA/cm2 and 1 g NaCl/L was highly improved by introducing 1 g/L of mordenite zeolite as an ion-exchanger. A remarkable removal of heavy metals was reported, as the initial concentration of each metal decreased from approximately 50 ppm to 1.19 for nickel, 3.06 for zinc, and less than 1 ppm for copper. In contrast, ultrasonication did not show any improvement in the treatment process. The extended Langmuir isotherm model convincingly described the experimental data; the Temkin and Dubinin-Radushkevich isotherm models have proven that the removal processes were physical and exothermic.

This negative impact can be mitigated by valorizing tobacco residue. In this study, tobacco residue was pretreated and the effect of dewaxing and washing on sugar and ethanol yields was studied. Tobacco residue was pretreated with alkali (2.17 M NaOH, 94 °C, 4.5 h) or acid (2.95 wt% H2SO4, 133 °C, 0.92 h). The effect of dewaxing was studied by incorporating the dewaxing step prior to pretreatment. Similarly, the effect of washing was analyzed by omitting post-pretreatment washing. Compositional analysis revealed that dewaxing prior to alkaline pretreatment improved cellulose content by 80% compared to the standard pretreated sample. Enzymatic hydrolysis of the samples showed that pretreatment had improved sugar yield by up to 6.1 times. Moreover, the sugar yield further improved when dewaxing and post-pretreatment washing steps were incorporated into the process. The unwashed biomass showed a 3-fold decrease in sugar compared to untreated biomass. Furthermore, fermentation studies showed that the dewaxed alkaline pretreated tobacco residue enhanced ethanol yield by 34% compared to standard pretreated biomass. Thus, this study reveals the potential of tobacco residue valorization and emphasizes the importance of dewaxing and post-pretreatment washing in a biorefinery.","PeriodicalId":8097,"journal":{"name":"Applied Science and Engineering Progress","volume":" 5","pages":""},"PeriodicalIF":0.0,"publicationDate":"2024-07-18","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"141824359","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

However, this widespread use of polypropylene also presents a significant challenge in the disposal of polypropylene waste and its durability aspects. So, the fused deposition modeling (FDM) technique arises as compiling outcomes for recycling discarded PP waste to create functional products. The properties of FDM components produced from recycled polypropylene (r-PP) are notably inferior to those of virgin PP FDM counterparts. Hence, it becomes imperative to comprehend the substantial alterations that r-PP undergoes during successive extrusion processes, including chain scission, alterations in viscosity, and reductions in breaking strength. The incorporation of additives has emerged as a promising solution to enhance the performance of r-PP. In this context, the present study explores the development of a novel composite material by blending r-PP with aluminum powder. The combination of these materials leverages the sustainability benefits of r-PP and the excellent thermal and mechanical properties of aluminum, making it a promising candidate for a wide range of applications. The tensile results show a significant increase in Young’s modulus for pre-heat treated composite specimen at 214 ℃ extrusion temperature.

The proposed work aims to achieve two key objectives: maximal power extraction and solar panel coating. To reduce the cost of coating material for solar panels, Silver Nano Particles (AgNPs) are first collected from the leaves of Rose periwinkle plants. This strategy aims to achieve maximal power extraction by coating solar panels with green synthesized silver nanoparticles. To reduce the cost of coating material, Rosy periwinkle plant leaves are used to synthesize silver nanoparticles or AgNPs. To ascertain the framework's capacity for measuring energy both before and after the panels are coated with AgNP, this study theoretically analyses the data. The power current and voltage-current characteristics of the study were validated, enabling an examination of the study's effectiveness. The coated type outperformed the normal solar panel by 2%, according to the results. With a new approach called Farmland Fertility Optimization – Maximum Power Position Tracking, the precise peak site for increased energy yield is discovered. The bi-directional converter is also utilized to mitigate stress and increase voltage gain. To improve the power quality with fewer harmonics, the 3-phase inverter and the LC filtering circuits are used. Finally, a variety of performance measures are used to confirm the results of coated solar panels using power-tracking control techniques. The findings suggest that AgNP-coated solar panels provide the best possible electrical energy with improved voltage, current, and power quality. Performance evaluation shows that the coated solar panel's power tracking efficiency has increased to 99% with decreased harmonics of 2.52%.","PeriodicalId":8097,"journal":{"name":"Applied Science and Engineering Progress","volume":"120 19","pages":""},"PeriodicalIF":0.0,"publicationDate":"2024-07-08","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"141666931","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
