The treatment of industrial waste water using cyanobacteria in photobioreactor for the removal of sulphide, COD and phenol. The microorganisms were collected from the effluent treatment plant of a petroleum refinery and a biofilm was developed in nutrient medium. The reactor was fed with cyanobacteria. After biofilm formation and acclimatization, the same procedure was followed for 16 days in a rectangular tray type photo bioreactor for the treatment of industrial waste water. From continuous mode of operation, it was found that the phototrophic microorganisms can degrade the pollutants present in industrial waste water. The removal efficiency of hardness 75 %, sulphide 95.8 %, COD 98.7 %, phenol 99.9 % and nitrate 83.7 % was studied. The present works shows that it is feasible to use cyanobacteria in a photo bioreactor for the treatment of industrial waste water.

In this investigation, composites consisting of polypyrrole (PPy), polyaniline (PAN), and sodium alginate combined with rice husk (RH) biomass were fabricated, utilizing them as adsorbents for naphthalene. The optimization of key process variables, including pH, pesticide concentration, composite dosage, contact time, and temperature were systematically undertaken to enhance the removal efficiency of naphthalene. Notably, the composites exhibited promising efficacy in adsorbing naphthalene, with native rice husk and PPy/RH (at pH 4), PAN/RH (at pH 5), and Na-alginate/RH (at pH 6) displaying the highest removal rates. Optimized conditions for composite dosage, temperature, and contact time were determined as 0.05 g, 30 °C, and 90 min, respectively, ensuring efficient removal of naphthalene. The adsorption capacities for naphthalene were found to be 22.04, 23.15, 23.89 and 21.67 (mg/g) for RH, PAN/RH, PPY/RH and Na-alginate/RH, respectively. The Langmuir isotherm and pseudo-first-order kinetics models aptly described the adsorption process onto the composite material. The surface morphology and functional groups involved in the biocomposite formation were examined through scanning electron microscope (SEM) and Fourier-transform infrared (FTIR) techniques. These analyses confirmed that PPy, PAN, and Na-alginate composites with RH biomass exhibit high effectiveness in naphthalene removal, showcasing their potential application in the remediation of naphthalene from effluents.

Climate change is a universal issue and plastic trash is the major cause of global warming. The present study was specifically designed to address the escalating plastic waste problem, the biodegradation of low-density polyethylene (LDPE) bags was investigated over an 8-week period using liquid culture approach. Bacterial strain (Pseudomonas putida) capable of degrading LDPE was isolated from common plastic garbage dumping sites. The strain was identified after sequencing analysis, as P. putida was evaluated for its effectiveness in degrading LDPE. Various analytical techniques, including weight loss, SEM, FTIR and GC-MS were employed to assess the degradation process. Results revealed that bacterial strain achieved 0.0776 % degradation. SEM and FTIR confirmed surface and chemical changes, while GC MS identified degradation by products in comparison to the control (where no bacteria was used).

The study concentrated on the fabrication of an environmentally friendly inhibitor, namely ethyl 4-(4-methoxyphenyl)-2,7,7-trimethyl-5-oxo-1,4,5,6,7,8-hexahydroquinoline-3-carboxylate derivative of quinoline (MQC), in a single step, and assessed its inhibiting property in highly acidic fluid (15 % HCl) for protecting Q235 steel at 1500 rpm rotation speed. Weight reduction, Potentiodynamic polarization, and electrochemical impedance spectroscopy were utilized in the study to investigate the inhibiting impact of MQC. The estimated findings corroborated the inhibiting data of 93.54 and 98.38 % at 308 K with 100 mg/L/only MQC and MQC + KI/75 mg/L + 0.5 mM, respectively, and the impact of temperature upon the inhibitory capability possessed little impact at larger dose quantities. According to the electrochemical outcomes, the MQC is a mixed-type corrosion inhibitor. The findings of the SEM, EDX, and AFM examinations demonstrated that the MQC established a barrier over the surface of Q235 steel by adsorption, changing the hydrophilic and hydrophobic attributes of the Q235 steel surface. An additional XPS assessment demonstrated MQC molecule adsorption on the Q235 steel surface. Density functional theory (DFT) and molecular dynamic simulations (MD) calculations were further performed to justify the experimental results.

Rheumatoid Arthritis (RA) is regarded as a long-term autoimmune disorder, which triggers inflammation in joints and distresses the organs in the body. Nanotechnology, a science-based technique is a tremendously growing-field with numerous applications where nanoparticles are used to resolve the complications in the habitual life. While comparing to other metals, iron oxide nanoparticles (Fe2O3 NPs) were synthesized at minimal cost using eco-friendly natured materials and also has ability to deliver drug at a specific targeted site. In the present study, a topical nanoemulgel was formulated using Fe2O3 NPs synthesized from Punica granatum. The results of Fe2O3 NPs characterization divulged that the particles were sphere-shaped in nature and the bioactive compounds from the extract acted as capping and reducing agents. Nanoemulgels (F1 to F5) were formulated using different concentrations of Fe2O3 NPs and characterized. Among the formulations F4 nanoemulgel revealed good stability with a zeta potential charge of −53 mV and a polydispersity index of 0.24. L929 cells were treated with F4 formulation and this confirmed that the formulation was non-toxic to normal cells. F4 treated MG63 cell lines revealed the anti-inflammatory property (IC50 = 90.77 μg/ml) of the nanoemulgel. Thus, nanoemulgel containing Fe2O3 NPs synthesized from P. granatum can be an effective, eco-friendly and cost-effective approach to treat RA.

Graphene oxide (GO) consists of many functional groups containing oxygen that helps in its chemical modifications. Thus, we have explored the synthesis, and corrosion inhibition application of n-butylamine (nBA) functionalized GO, i.e., GO-nBA for N80 steel in the acidizing environment (15 % HCl). NMR and TEM characterized the GO-nBA. The performance of GO-nBA was evaluated via chemical and electrochemicals methods that are supported by surface examination techniques. The PDP results supports the mixed nature of protection ability of GO-nBA. Additionally, the excellency of GO-nBA is confirmed by the value of 93.93 % efficiency. The surface study furthermore represents smooth texture with the addition of GO-nBA. The computational analysis reveals excellent inhibitive performance of GO-nBA.

The rational construction and design of nanostructured materials have a significant impact on the fabrication of high-performance electrode materials, which have attracted considerable interest in an effort to enhance the reliability and efficiency of energy storage devices. In this study, the α-ZnMoO4 nanoparticles were successfully prepared by facile hydrothermal method and the influence of various hydrothermal reaction times on structural, morphological, optical and electrochemical properties were studied. XRD analysis illustrated that α-ZnMoO4 nanoparticles exhibited anorthic crystal structure and the average crystallite size was 42 nm. FESEM images changed from a cubic structure to plate-like structures depending on reaction times. HRTEM analysis revealed that prepared sample showed a plate-like structure and the SAED pattern exhibited a polycrystalline nature. The FTIR spectrum confirmed the presence of vibrational molecules in α-ZnMoO4 nanoparticles. The BET and XPS measurements showed the α-ZnMoO4 nanoparticles were mesoporous and had Zn2+ and Mo6+ oxidation states, respectively. From UV–Visible spectra, a better spectral selectivity region was observed at higher reaction times, and the bandgap values were decreased from 2.73 to 2.48 eV. In photocatalytic studies, RhB dye was used as an organic pollutant and achieved a degradation efficiency of 85 % at an optimized reaction time of 24 h. For electrochemical performances, the prepared electrode material showed maximum specific capacitance values of 165 F g−1 and 110 F g−1 for cyclic voltammetry and galvanoststic charge-discharge analysis, respectively.

For electrochemical performances, the prepared electrode material showed maximum specific capacitance values of 165 F g−1 and 110 F g−1 for cyclic voltammetry and galvanoststic charge-discharge analysis, respectively.","PeriodicalId":506520,"journal":{"name":"Zeitschrift für Physikalische Chemie","volume":"6 19","pages":""},"PeriodicalIF":0.0,"publicationDate":"2024-02-12","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"139783095","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}

Graphene oxide (GO) consists of many functional groups containing oxygen that helps in its chemical modifications. Thus, we have explored the synthesis, and corrosion inhibition application of n-butylamine (nBA) functionalized GO, i.e., GO-nBA for N80 steel in the acidizing environment (15 % HCl). NMR and TEM characterized the GO-nBA. The performance of GO-nBA was evaluated via chemical and electrochemicals methods that are supported by surface examination techniques. The PDP results supports the mixed nature of protection ability of GO-nBA. Additionally, the excellency of GO-nBA is confirmed by the value of 93.93 % efficiency. The surface study furthermore represents smooth texture with the addition of GO-nBA. The computational analysis reveals excellent inhibitive performance of GO-nBA.
