This research splits shale gas well production into five flow stages, to better understand the variables influencing EUR following shale gas fracturing and qualitatively evaluate the effect degree of each element on EUR. We fully examine contemporary research on the influencing variables of EUR following shale gas fracturing from three perspectives: geology, engineering, and production, and explain in detail 13 major regulating parameters impacting EUR in different flow phases. Based on the analytic hierarchy process (AHP), an evaluation model for the primary regulating elements of EUR following shale gas fracturing has been constructed. To test the novel model, actual data from production wells in a shale gas field in China was used. The optimal well for the current production system after shale gas fracturing is determined, and suggestions and improvement directions for the remaining gas wells’ production systems are proposed.International Journal of Industrial Chemistry (IJIC)Environmental assessment of bamboo-based multilayer composites: a life cycle analysis perspectiveVolume 15 (2024)Issue 2, July 202420240727Environmental assessment of bamboo-based multilayer composites: a life cycle analysis perspective10.57647/j.ijic.2024.1502.10ENWeiweiTianMaterial Engineering College, Fujian Agriculture and Forestry University, Fuzhou, Fujian, ChinaGuangyaoDuMaterial Engineering College, Fujian Agriculture and Forestry University, Fuzhou, Fujian, ChinaMinghuiGuoMaterials Science and Engineering College, Northeast Forestry University, Haerbin, Heilongjiang, ChinaXueshenLiuMaterial Engineering College, Fujian Agriculture and Forestry University, Fuzhou, Fujian, China0009-0005-2117-6595Journal Article20240727Bamboo-based multilayer composite materials are a new type of bio-composite material with high strength, wide applicability, and low cost. Based on the life cycle assessment (LCA) method, this paper analyzes the energy consumption and harmful substance emissions of producing 1m3 of this product using the basic data inventory provided by the material processing enterprises, GaBi 6.0 software, and the CML2016 method. Results show that in the production and manufacturing process of bamboo-based multilayer composite materials, the environmental impact category with the most significant influence is acidification (AP), accounting for 53.27%, followed by marine aquatic ecotoxicity (MAETP) and eutrophication (EP). In its production, the environmental load mainly comes from bamboo combustion (for energy) and rough planing (to remove bamboo green and bamboo yellow), which account for 74.59% and 6.93% of the total environmental load, respectively. The study also found that burning waste bamboo can meet the factory’s energy self-sufficiency, and except for eutrophication (EP) and acidification (AP), all other environmental loads are less than that of coal and natural gas combustion. Based on the above analysis, bamboo-based multilayer composite materials possess low-carbon, energy-saving, and environmentally friendly characteristics.International Journal of Industrial Chemistry (IJIC)Morphology dependence of photocatalytic activity of zinc oxide nanostructures on water disinfectionVolume 15 (2024)Issue 2, July 202420240727Morphology dependence of photocatalytic activity of zinc oxide nanostructures on water disinfection10.57647/j.ijic.2024.1502.11ENSekinehKhodadadPhysics Department, Takestan Branch, Islamic Azad University, Takestan, IranDavoudDorranianLaser Lab., Plasma Physics Research Center, Science and Research Branch, Islamic Azad University, Tehran, Iran0000-0001-8855-7425PeymanAzimi AnarakiPhysics Department, Takestan Branch, Islamic Azad University, Takestan, IranRezaMirnejadMolecular Biology Research Center, Baqiyatallah University of Medical Sciences, Tehran, IranTaniaDavari MahabadiDepartment of Physics and Biophysics, Faculty of Health, Tehran Medical Sciences, Islamic Azad University, Tehran, IranJournal Article20240727Dependence of the photocatalytic activities of zinc oxide (ZnO) nanostructures on their morphology was investigated experimentally. Spherical and nanorod morphologies of ZnO nanostructures were synthesized by laser ablation and hydrothermal methods respectively, and were characterized by FESEM images and UV-Vis-NIR spectra. The bandgap energy of ZnO nanospheres was 3.75 eV, while for the ZnO nanorods the bandgap energy was 3.07 eV. Their photocatalytic activities to decontaminate water polluted Escherichia coli (E. coli) bacteria were examined in the dark condition and under the UV irradiation. Furthermore, effects of other parameters including size, illumination power, and time were observed. The ZnO nanorods exhibited higher inactivation efficiency in comparison with spherical nanostructures. Results show that in the decontamination process, after distraction of the membrane of E. coli, the intercellular dissolved matters including proteins, and sugars flowed out gradually leaded to complete decay of the cell. Results confirm that the area and bandgap energy of nanostructures have determinative role in their photocatalytic activities.International Journal of Industrial Chemistry (IJIC)Microbial and organic carbon mineralization in saline soil aggregates under different microplastic concentrationsVolume 15 (2024)Issue 2, July 202420240727Microbial and organic carbon mineralization in saline soil aggregates under different microplastic concentrations10.57647/j.ijic.2024.1502.13ENZhenLiuCangzhou Academy of Agriculture and Forestry Sciences, Cangzhou, China0009-0008-4970-0418XiaolongZhaoCangzhou Academy of Agriculture and Forestry Sciences, Cangzhou, ChinaWanyanZhouCangzhou Academy of Agriculture and Forestry Sciences, Cangzhou, ChinaYuanyuanLiuCangzhou Academy of Agriculture and Forestry Sciences, Cangzhou, ChinaPingpingCaoCangzhou Academy of Agriculture and Forestry Sciences, Cangzhou, ChinaJiaxuanWuCangzhou Academy of Agriculture and Forestry Sciences, Cangzhou, ChinaXueruiGuoCangzhou Academy of Agriculture and Forestry Sciences, Cangzhou, ChinaYupengXuCangzhou Academy of Agriculture and Forestry Sciences, Cangzhou, ChinaJournal Article20240727Plastic products are widely used in various fields, but the lack of effective means of recycling and disposal has led to the spread of plastics in the form of particles throughout the ecosystem. To examine the impact of microplastics on saline soils, the study was verified experimentally by adding microplastics of different sizes and concentrations to saline soil samples. The results showed that 25 um microplastics decreased the dissolved organic carbon content of organic matter saline soil, but had little effect on high organic matter soil samples. On the other hand, 1 mm microplastics increased the dissolved organic carbon content of organic matter soil samples; the highest organic carbon content was found at a microplastic concentration of 1.92 g/kg. Meanwhile, microplastics of different sizes increased the microbial amount carbon content of the soil samples, with increases ranging from about 24.3% to 108.9%. In addition, small diameter microplastic particles increased the rate of organic carbon mineralization in saline soils by up to 38.5%. Large diameter microplastic particles decreased the rate of organic carbon mineralization by up to 32.2%. The results demonstrate that the microplastic particle size can indirectly influence the water stability aggregate content by affecting the soil organic carbon mineralization rate and the soil microbial biomass and carbon content. This study examines the relationship between microplastics and
soil biochemical processes under the influence of both biological and abiotic factors, which is of great significance for understanding the potential impact of microplastic pollution on carbon sequestration.International Journal of Industrial Chemistry (IJIC)Synthesis of novel products from the reaction of benzaldehyde and benzoic acid derivatives with aromatics carrying two hydroxyl groups under microwave irradiationVolume 15 (2024)Issue 2, July 202420240727Synthesis of novel products from the reaction of benzaldehyde and benzoic acid derivatives with aromatics carrying two hydroxyl groups under microwave irradiation10.57647/j.ijic.2024.1502.14ENNargesSamooriDepartment of Chemistry, Tehran North Branch, Islamic Azad University, Tehran, Iran0009-0000-7284-7073NaserForoughifarDepartment of Chemistry, Tehran North Branch, Islamic Azad University, Tehran, Iran0000-0002-3602-0084AlirezaKhajeh-AmiriToxicology Research Center, Aja University of Medical Sciences, Tehran, Iran0000-0003-0562-3015HodaPasdarDepartment of Chemistry, Tehran North Branch, Islamic Azad University, Tehran, Iran0009-0007-2174-5393Journal Article20240727The bond-forming of Carbon-heteroatom and carbon-carbon are the spinal columns for synthetic organic chemistry. Today, scientists constantly attempt to establish novel approaches for such bondforming reactions based on green chemistry since they are valuable instruments for synthesizing molecular entities with diverse structures. An effective one-pot four-component method was studied for the synthesis of (5-hydroxy-2,4-dipheny-2H-benzo[e][1,3]oxazin-3(4H)-yl)(phenyl)methanone derivatives by the condensation reaction of Resorcinol with various aromatic aldehydes, carboxylic acids, and ammonia. The reaction was carried out in an aqueous medium under reflux/ microwave irradiation conditions with short reaction times, resulting in high yields. The chemical structures of all synthesized compounds were determined using elemental analysis, FT-IR, 1HNMR, and 13CNMR spectroscopies.International Journal of Industrial Chemistry (IJIC)Pre industrialization assessment of polyclonal IgY antibodies to whole-cell S. mutansVolume 15 (2024)Issue 2, July 202420240727Pre industrialization assessment of polyclonal IgY antibodies to whole-cell S. mutans10.57647/j.ijic.2024.1502.15ENSamanehSadat Rasi VaraeiDepartment of Clinical Biochemistry, School of Medicine, Tehran University of Medical Sciences, Tehran, Iran0009-0003-5218-7815AliasgharRahimianDepartment of Clinical Biochemistry, School of Medicine, Tehran University of Medical Sciences, Tehran, Iran0000-0003-2423-1455HoomanAskariDepartment of Clinical Biochemistry, School of Medicine, Tehran University of Medical Sciences, Tehran, Iran0000-0002-4940-2970AbbasBahadorDepartment of Microbiology, School of Medicine, Tehran University of Medical Sciences, Tehran, Iran

Various strategies have been developed and proved beneficial in managing the disease; however, novel techniques have also been investigated. One of such strategies involves the administration of polyclonal antibodies (passive immunization), usually in the form of an oral mouthwash. While many studies have taken place over the years, to our knowledge, the effectiveness of these antibodies in prevention of the biofilm formed by different S. mutans isolates of the same serotype has not been investigated. Nine clinical isolates of S. mutans were obtained, all serotype c. Gtf-B was purified and together with one of the clinical isolate (SM4), were used as antigen for hen immunization. IgY polyclonal antibodies were purified, and applied to wells containing a distinct S. mutans isolate. Bacteria growth and biofilm formation was investigated by measuring absorbance at 600 nm and performing a biofilm assay based on crystal violet. Polyclonal antibodies to Gtf-B reduced bacterial growth between 9 and 35% compared to controls in four clinical isolates (P<0.05). As for biofilm formation, the polyclonal antibodies to Gtf-B inhibited biofilms by 17-54%, which was significant for all clinical isolates (p<0.05). On the other hand, polyclonal antibodies to whole-cell S. mutans reduced bacterial growth from 43 to 61%, which was meaningful for all isolates as well as the control strain (SM25175). As for biofilm formation, the anti-whole-cell antibodies reduced biofilm formation by 6-51%, which was significant for only four strains.International Journal of Industrial Chemistry (IJIC)Synthesis of photocatalytic material based on polyaniline supported PVC/NiAl2O3/AlF3 nanocompositeVolume 15 (2024)Issue 2, July 202420240727Synthesis of photocatalytic material based on polyaniline supported PVC/NiAl2O3/AlF3 nanocomposite10.57647/j.ijic.2024.1502.16ENIlnazAhmadianDepartment of Chemistry, Islamic Azad University, North Tehran Branch, Tehran, IranMaryamKargar RaziDepartment of Chemistry, Islamic Azad University, North Tehran Branch, Tehran, Iran0000-0001-5788-9849BabakSadeghiDepartment of Chemistry, Islamic Azad University, Tonekabon Branch, Tonekabon, Iran0000-0003-0933-5782MahbobehNakhaeiDepartment of Chemistry, Islamic Azad University, North Tehran Branch, Tehran, IranJournal Article20240727In this research, photocatalysis single AlF3, Ternary PVC/Al2O3/AlF3 (PNA) and polyaniline (PAI) supported PNA nanocomposite were synthesized by co-precipitation method. Surface area and morphological structure of the synthesized photocatalysts were characterized by X-ray Diffractometer (XRD), Brunauer-Emmett-Teller (BET), and Scanning Electron Microscopy (SEM). With the best conditions, the response in the glassy carbon electrode (GCE) showed concentrations
of the malathion in the range values of 1.5-11 ×10−7 M, high recovery values around 98.4% with the good reproducibility. The stunning simplicity for preparation, and selectivity of this nanostructure and high sensitivity of polyaniline supported PNA electrode can make it a good candidate for application in detection of malathion.
