In this context, we developed a low-cost photolytic system to improve the efficiency of methylene blue (MB) dye removal. Based on biochar derived from sugarcane biomass, the proposed composites were prepared with various metal oxides (TiO₂, ZnO, and CuO). Their photocatalytic property was tested in the dispersion of the biochar composite powder in the solution and a biochar composite-based porous matrix built from a commercial polyurethane sponge. High photodegradation rates of the MB dye were observed: 96 % and 98 % for dispersed powder of TiO₂@biochar and ZnO@biochar, respectively, in 230 min and at room temperature. By applying a temperature of 50 °C, an efficiency of 95 % was achieved within 30 min of the photocatalysis. When immobilized on the polyurethane (PM) matrix, the results for TiO₂@biochar and ZnO@biochar showed the same tendency. After three heterogeneous photocatalysis cycles, both materials showed promising results for reuse. Moreover, the main advantage of using the PM matrix is the easy recovery, avoiding significant material loss.

Polyethylene Terephthalate Glycol (PETG) plastic was used to create a PCM container utilising 3D printing technology, which solved leakage problems and increased durability. Aluminium oxide (Al₂O₃) nanoparticles (75 nm) were added to Micronal® DS 5008 X, an organic paraffin wax-based PCM, at different mass percentages (1 %, 2 %, and 3 %), to improve thermal conductivity. This PCM was chosen for its exceptional thermal energy storage capabilities. In order to ensure uniform nanoparticle distribution, ultrasonic dispersion was used to create the nanoparticle-enhanced PCM (n-PCM) mixes. K-type thermocouples and silicone rubber heaters were used in the experimental setup to imitate high sun irradiation conditions, and temperature readings were taken with a data logger. Thermal characteristics of PCMs and n-PCMs were evaluated using Differential Scanning Calorimetry (DSC) analysis. As a consequence of the considerable reduction in operating temperatures and improvement in thermal conductivity, the results showed that adding 2 % Al₂O₃ nanoparticles produced the best thermal control. Though they were still within practical limits for thermal energy storage, the latent heat of fusion and heat capacity were somewhat decreased with the inclusion of nanoparticles. At 1 % and 2 % Al₂O₃ concentrations, the heat transfer coefficients were improved; at higher concentrations, however, thermal performance was reduced due to nanoparticle aggregation and increased viscosity. Electrical performance investigation demonstrated a 12 % reduction in energy consumption and a peak photovoltaic (PV) system efficiency of 16.0 % with 2 % Al2O3.

After stabilizing the system, two layers of water molecules were obtained on the metal, with the first layer having hydrogen atoms oriented upwards and the second layer having hydrogen atoms oriented downwards. We found that as water molecules approached the surface, there was an increased deviation in the geometric parameters and dipole moment of the upward-oriented water molecules compared to those oriented downwards. We demonstrated that the presence of the metallic substrate contributes to increasing the polarization of the water molecule, such that the dipole moment of the water molecule at the surface is greater than that of the isolated molecule measured experimentally (μ = 1.855 D). Since the dipole moment is a vector quantity oriented from the negative pole to the positive pole, the total dipole moment required us to calculate the angle between water molecules with different orientations. We found that these angles are approximately linear (θ ≈ 180°), and we confirmed that the total dipole moment increases rapidly and exponentially as the molecules approach the surface.</div></div>","PeriodicalId":17276,"journal":{"name":"Journal of the Indian Chemical Society","volume":"102 2","pages":"Article 101597"},"PeriodicalIF":3.2,"publicationDate":"2025-02-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143140688","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"化学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
