This research explores the potential of 2-(2-Aminopropyl)thiazole (APT) as an inhibitor for corrosion of MS in 1 M HCl environment through methodological and DFT combination study. The inhibitory performance of APT reached an impressive efficiency of 88.2 % under optimized conditions (0.5 mM inhibitor concentration, 303 K), demonstrating its promise as an environmentally friendly alternative. Analysis based on Langmuir adsorption isotherm indicated strong and specific interactions between APT molecules and the steel surface, suggesting the formation of a protective film over time. The correlation between inhibition efficiency, immersion time, and temperature revealed a gradual enhancement of the protective effect, with temperature positively influencing the inhibitor's effectiveness, indicative of a thermally activated adsorption process. Calculations of Density Functional Theory (DFT) supported experimental findings and provide insights into molecular interaction at the interface. Just in these case, the calculated theory of electron transfer suggested that the interaction between APT and the atoms of iron was more favorable what shifted the inhibition process in a good direction. This work not only provide important information about the role of corrosion inhibiting but also relies on a reliable methodology that can be genralised to the analysis of eco-friendly corrosive preventing substances. Moreover, the research results provide a basis for the future development of APT for industrial application, which will deal with the real-world problems in the world.https://pccc.icrc.ac.ir/article_82020_9f8bf30680dba7adcc04ecd75e1c26d1.pdfInstitute for Color Science and Technology (ICST)Progress in Color, Colorants and Coatings2008-213418220250501Optical and Morphological Properties of Poly(vinyl chloride) Thin Films with Organic Content Reinforced by Nanoparticles Embedded which is Freestanding1451628202210.30509/pccc.2024.167313.1300ENR.

PVC was modified with 25 g of the organic material domperidone (PVC/D) and subsequently doped with 0.01 g of Co3O4, NiO, and Cr2O3 NPs to create the modified nanocomposite thin films, PVC/D/Co3O4, NiO, and Cr2O3, the NPs dimeters was < 50 nm. These films were investigated using diffusive reflectance within the 250-1350 nm wavelength range. The X-ray diffraction (XRD) analysis revealed a semi-crystalline structure for the modified PVC. The optical properties of the modified nanocomposite thin films were assessed, resulting in decreased transmittance and reflectance values, with absorption coefficients ranging from 88 to 94 %. Upon NP doping, the nanocomposite thin films' direct and indirect energy band gaps decreased from 4.7 to 3.0 and 4.3 to 2.9 eV, respectively. This decrease was attributed to an increase in localized states, leading to higher disorder within the material following an increase in Eu from 0.862 to 3.096 eV. Scanning electron microscopy (SEM) analysis illustrated the nanocomposite structure of modified PVC. In contrast, the measurements of atomic force microscopy (AFM) indicated increased surface roughness from 2.31 nm to 6.16 nm for the modified PVC thin films. These modified PVC nanocomposite thin films find potential applications in various industries, including air transport components, light-emitting diodes, laser sensors, UV energy shielding, light-harvesting devices, memory devices, and light-conversion technologies. https://pccc.icrc.ac.ir/article_82022_2a6e9744494c08993c35be89dadbc972.pdfInstitute for Color Science and Technology (ICST)Progress in Color, Colorants and Coatings2008-213418220250501Surface Modification of Cotton Gauze by Silk Fibroin Nanofibers as Compatible Biomaterial1631768203010.30509/pccc.2024.167308.1299ENA.ZareDepartment of Textile Engineering, Yazd University, P.O. Box: 8915818411, Yazd, Iran.Journal Article20240424The present research explores preparing and characterizing silk fibroin electrospun nanofibers on cotton gauze bandages to form a novel silk-gauze nanocomposite. The presence of the extracted silk fibroin on the cotton substrate surface was demonstrated by scanning electron microscopy (SEM), attenuated total reflectance Fourier transform infrared spectrophotometry (ATR-FTIR), wide-angle X-ray diffraction (WAXD) and K/S values. The SEM images of cotton samples revealed the deposition of silk fibroin from silk fiber on the substrate surface. The dyed silk-gauze nanocomposite wound dressing presented significantly higher color strength than an uncoated gauze bandage. The physical properties of nanocomposite samples, i.e., porosity, tensile strength, bending characterizations, air permeability, and water uptake, were measured. The changes in the secondary structure of silk fibroin, morphology, crystallinity, hydrophilicity as well as cytotoxicity of nanocomposites were analyzed before and after undergoing treatments with ethanol and methanol. The results demonstrated a decrease in water uptake and porosity values and a slight increment in tensile strength and bending characterization of the treated nanocomposite samples compared to the untreated samples. MTT assay as an indirect cytotoxicity method showed cytocompatibility of the silk-gauze nanocomposite wound dressing. The indirect cytotoxicity results showed that samples treated with ethanol demonstrated no cytotoxicity on the L929 cancer cell line.https://pccc.icrc.ac.ir/article_82030_26df76fcb3873b015c783b70f748a5cd.pdfInstitute for Color Science and Technology (ICST)Progress in Color, Colorants and Coatings2008-213418220250501Optimizing the Surfactant/Polymeric Dispersant Combination in Pigment-Based Aqueous Inkjet Inks1771888204010.30509/pccc.2024.167361.1316ENM.JaliliDepartment of Printing Science and Technology, Institute for Color Science and Technology, P.O.

Box: 32465-654, Tehran, IranJournal Article20240814Pigment-based inkjet printing offers numerous advantages over traditional contact printing techniques; however, these inks require stringent dispersion properties and a delicate balance between rheological behavior and surface tension. This study addresses these challenges by exploring and optimizing the combination of surfactants and dispersing agents. We aimed to achieve a stable nanosized dispersion of Disperse Blue 359 in aqueous pigment-based inkjet inks while adjusting its rheological properties using a polymeric dispersant and surfactants. Various formulations with different surfactants and polymeric dispersant concentrations were assessed for rheological behavior, surface tension, particle size distribution, and dispersion stability. Among the assessed surfactants, the surfactant with the lowest hydrophilic-lipophilic balance offered the lowest and most stable particle size. It also showed the best performance during milling and almost Newtonian rheological behavior. It was attributed to its higher tendency to absorb on the particle surface. The optimization of polymeric dispersant concentration also revealed that samples with too low dispersant, experience flocculation rapidly after milling due to insufficient dispersant to cover the fresh surface of ground particles. On the other hand, samples with too high dispersant concentration have stability issues and also non-Newtonian rheological behavior because of too thick absorbed layer of dispersant on the particle surface and high concentration of non-absorbed polymer chains in the media. The optimized combination resulted in a stable nanosized pigment dispersion with low viscosity and Newtonian behavior. These findings provide valuable insights into formulating high-performance pigment-based inkjet inks, highlighting the critical interplay between dispersants and surfactants in achieving optimal performance. https://pccc.icrc.ac.ir/article_82040_4f60ef0446446851dbdeb01f21ade7f9.pdfInstitute for Color Science and Technology (ICST)Progress in Color, Colorants and Coatings2008-213418220250501Enhancing the Mechanical and Electrical Properties of Adhesive Coating Materials by Cu@Sn Core Shell Nanomaterials Mixed with Hybrid Polymeric Composite Material1891998204410.30509/pccc.2024.167342.1311ENJ.

The result was a cost-effective nanocomposite used as an adsorbent and photo-degradation with exceptional organic pollutants (OP) in refinery wastewater (RWW). This composite exhibited outstanding mechanical stability and eliminated organic pollutants (OP) by oxidation and adsorbent. All materials were comprehensively characterized through XRD, FTIR, DRS, TGA, BET, EDX, XRD, and FE-SEM analyses. A comparison was made between the nanocomposite's UV and solar light performance, considering factors like temperature, pH, time, dose, and so on. The best conditions were identified: pH levels of 8-9, time of 120 minutes, temperature of 70 °C, and dose of 1.0 g. Upon applying these optimized conditions to RWW samples, the high removal ratios were achieved: 97.4, 90.3, 64.2, and 49 % for CoWO4/NCW, NCW, NaOH/CW, and CW respectively. These findings underscore the composite's potential as an economical and efficient biosorbent for OP elimination, alongside its effectiveness in solar-assisted degradation processes.https://pccc.icrc.ac.ir/article_82049_d934b32c90acf637efa644e3c32fe87a.pdfInstitute for Color Science and Technology (ICST)Progress in Color, Colorants and Coatings2008-213418220250501Current Trends in Cool Coating Technology2192328201110.30509/pccc.2024.167293.1286ENSh.MontazeriDepartment of Surface Coatings and Corrosion, Institute for Color Science and Technology, P.O.

The materials of the building and urban fabric have an impact on the thermal balance of the city and significantly increase the risk of urban warming. This review describes advances in the design, manufacture and application of ultra-low and low surface temperature coatings for buildings and equipment. It covers the definitions, mechanisms, evaluations, and recent technological advances of natural, light-colored, infrared solar reflective, PCM-doped, thermochromic, quantum dot, and plasmonic cool materials. A comparative analysis of the experimental results on the cooling capacity and thermal performance of the traditional or new materials is provided. It is shown that natural cool coatings can reflect 80-90 % of solar energy and save 18 % of cooling energy, white and colored cool pigments can exhibit 85-95 % solar reflectance, and novel cool materials can reflect more than 93 % of solar thermal energy. In addition, PCM-doped cool coatings can reduce the surface temperature by 2.5 to 19.7 °C. The aim is to present the best method among those proposed in terms of energy and raw material cost for cool coatings. This review also explains how cool coatings with high solar reflectance can absorb less solar energy and increase the lifetime and efficiency of power systems and electronic devices that are typically exposed to sunlight. https://pccc.icrc.ac.ir/article_82011_b81940fdbf1c15b6958bcb2a3d949e5a.pdfInstitute for Color Science and Technology (ICST)Progress in Color, Colorants and Coatings2008-213418220250501Harnessing Herbaceous Plants as an Eco-Friendly Source of Carbon-Based Adsorbents for Water Remediation: A Review2332658204110.30509/pccc.2024.167340.1309ENN.AlbayatiDepartment of Chemical Engineering, College of Engineering, University of Baghdad, P.O.

This research explores the diverse adsorption potential of herbaceous plants, particularly Rosaceae, Paeoniaceae, Malvaceae, and Asteraceae, to improve eco-friendly and efficient water remediation technologies. The study catalogs 22 herbaceous plants using Scopus data and focuses on pollutant adsorption. Rose waste (especially ultimate rose pulp) and rose flower biomass may remove wastewater pollutants. Novel biomass treatments like coating, pyrolyzing, soaking in activating solutions, and synergizing with additives increase pollutant water adsorption. Spent Alchemilla vulgaris leaves absorb methylene blue dye well. Paeoniaceae, represented by Paeonia ostii seed coats, showed novel heavy metal adsorbents with excellent capacities and reusability. Hibiscus species of Malvaceae show phytoremediation potential, removing dyes and adsorbing Safranin dye with activated carbon from Hibiscus cannabinus. In the Asteraceae family, sunflower-based adsorbents for water treatment were studied for various pollutants using biochar modification, chemical treatment, and nanoparticle incorporation. The exceptional adsorption properties of biochar, the cost-effective production of activated carbon, the versatility of sunflower straw-activated carbon, and the use of nanoparticles-coated sunflower husk were found for simultaneous antibiotics adsorption and dye removal. Marigold and Chamomile, Asteraceae plants, are versatile environmental adsorbents. This comprehensive research uses herbal-based adsorbents due to their efficacy, economic viability, and environmental sustainability.https://pccc.icrc.ac.ir/article_82041_9385ce03c6437567e0a7da3e5a522a32.pdf
