Central composite design approach for concurrent desulfurization and denitrogenation of model liquid fuel over Mo ‐AAC
AbstractThe primary objective of this work was to investigate the simultaneous removal of refractory sulfur (dibenzothiophene, DBT) and nitrogen compounds (indole, IND) from model gasoline. This research aimed to develop an efficient adsorption process to mitigate the emission of sulfur oxide and nitrogen oxides, which pose direct threats to human health and the environment. Additionally, the study focused on addressing technical challenges encountered in the refinery process, particularly the poisoning of catalysts due to the presence of these compounds. To achieve the study's goals, granular activated carbon (GAC) was su...

Identification and acclimatization of the most potential 4 ‐chlorophenol degrading bacterial strain isolated from hazardous soil and observing its performance in various process parameters
Abstract4-Chlorophenol is present as an essential compound of various organic compounds found in different kinds of hazardous waste. It can be easily eliminated from the industrial effluents by different physical and chemical treatment methods although best technique is bioremediation. To separate a potent bacterial strain from the soil that can dispose of 4-chlorophenol from contaminated water, soil sample was collected from a hospital zone. Isolated bacterial colonies were segregated by the technique of soil enrichment with 500 mg/L 4-chlorophenol and after that the enriched soil sample was serially diluted and transfe...

Biofilm and metallothioneins: A dual approach to bioremediate the heavy metal menace
AbstractMetallothioneins are a class of proteins produced by both prokaryotes and eukaryotes, having low molecular weight and abundant cysteine residues. These proteins play a humongous role in binding, sequestration, and even buffering of the intracellular metal ions. Though they are a wide class of proteins, much of them are yet to be explored. Their metal binding attribute is unique and they form distinctive metal-thiolate clusters. They have also been known to have ROS scavenging activities due to the presence of the cysteine residues. Phytochelatins also play major roles in metal sequestration pathways. Biofilms on th...

Investigation of photocatalytic performance of single layer superhydrophilic film: TEOS/PF ‐127
AbstractMultifunctional antireflective coatings (ARC) have great importance in various applications such as optical devices, flat panel displays, solar cell devices, and so on. Here in this work, highly transparent superhydrophilic film was developed on a cleaned glass substrate by depositing porous TEOS/PF-127 using the spin coating technique. The coating shows a maximum transparency of 95% in the visible region (400 –800 nm). The morphology and porous nature of the prepared sample was analyzed using FESEM and BET analysis respectively. The prepared film exhibited a water contact angle of 9° ensures its superhydrophil...

Machine learning approach for determining the water quality of freshwater lakes: A case study on selected lakes of Chennai, India
This study portrays an economical, user-friendly, economical method to detect water quality. A machine learning-based portable water quality check test kit was developed along with a user interface. To validate the efficiency of the portable kit, this study focussed on the ten major freshwater lakes of Chennai City. Basic quality parameters of water, such as the potential of hydrogen (pH), level of ammonia, nitrite, nitrate, and total phosphate (T.P.), were considered when designing this mobile phone-compatible user interface application. The experiment used and tested water samples from ten different lakes with the commer...

Environmental assessment of heavy metal contamination at Chekfa aggregate quarry (Jijel, North ‐East Algeria)
AbstractIt is fascinating to observe the potential hazards associated with mining and quarrying activities, despite the limited number of comprehensive studies conducted in Algeria to evaluate their environmental impact. This particular investigation focuses on El M'cif quarry in Chekfa, located within the Nil watershed in Jijel, a region situated in the North-East of Algeria. The primary objective is to assess the concentrations of lead (Pb), zinc (Zn), copper (Cu), and cadmium (Cd) in surface water, groundwater, stream sediments, and soil. Consequently, a suite of petrographic and geochemical analyses is undertaken to di...

Review of green technologies for the removal of microplastics from diverse environmental sources
AbstractMicroplastics are the basic particles (1 µm–1 mm), derived from degradation of polymers with maximum molecular weight via various sources. They occur in a variety of shapes and sizes, in the form of domains, particles, and fibers. Release of Microplastics in the ecosystem, due to deterioration of macroplastics are now being considere d as major toxic pollutants. Accumulation of microplastics in the diverse ecosystems is known to cause severe health and ecological effects. Since it is mandatory to take steps towards the removal of microplastics through effective and safe technology, with this objective, the pr...

Perceived enablers and barriers impacting sustainability of small ‐and‐medium sized enterprises: A quantitative analysis in four European countries
AbstractSmall and medium-sized enterprises (SMEs) often lag behind major corporations in implementing sustainability management practices, limiting their capacity to mitigate negative social and environmental impacts. A notable challenge is the lower percentage of SMEs with sustainability objectives. This research aims to examine the links among sustainability practices and performance of European SMEs. In addition, the causal relationships between enablers/barriers for sustainability practices are also examined. To achieve these objectives, a quantitative research approach was employed. Data were collected from 420 SMEs l...

Modeling and optimization of the yield of pyrolytic oil from waste face masks using RSM ‐ANN‐LM hybrid approach
AbstractPyrolysis is one of the most widely practiced thermochemical conversion technique to convert biomass into bio fuel. In this investigation, waste surgical masks were taken for pyrolysis process and the pyrolysis oil yield was determined experimentally. The experiments were designed and optimized based on Box Behnken Design (BBD) with operating parameters (feed size, temperature, and time) to study the effect on the yield of the pyrolysis oil and char. Experiments were conducted by varying the feed size (10 –50 mm), pyrolysis temperature (400–600°C), and time (30–90 min). A hybrid Response Surface Methodolog...

An experimental investigation of textile dyeing wastewater using modified electro Fenton process with optimization by response surface methodology
In this study, the average coefficient of correlation was 0.9978, indicating that the framework could describe 99.78% of the variability in response. The Analysis of variance (ANOVA) of the quadratic regression analysis shows that the model is incredibly substantial, as displayed by th e FisherF-test (F model = 347.52) with the lowest probability value (p model > F = 0.0001). The predicted results from Response Surface Methodology (RSM) closely agreed with the experimental results obtained during the optimization studies and hence confirmed the results obtained.
