The thermal properties were examined through differential scanning calorimetry (DSC). The melting point and latent heat of fusion of PCM was 20.84 °C and 240.60 J/g, while capsules showed a latent heat of 192.66 J/g with the same melting point. The formation of copolymer between DVB and St and their interaction with octadecane for the possibility of forming other copolymer is analyzed through, Fourier transform infrared spectrometry (FTIR). The spherical morphology of the capsules in slurry and core/shell structure was confirmed by the Field emission scanning electron microscope (FESEM)), respectively. Dynamic light scattering (DLS) analysis was used to verify and justify the sized capsules between 800nm and 30μm. From the application point of view, the Thermogravimetric analyzer (TGA) determined the thermal stability of the slurry. Synthesized slurry is used to manage the temperature in the system working under high-pressure condition such as PVT colling system as Heat transfer fluid.

This study focuses on the fabrication and evaluation of three different ceramic membranes, namely CM-0, CM-20, and CM-40. These membranes were prepared using an extrusion process with varying compositions: CM-0 consisted of 77% natural clay, 21% water, and 2% sugar solution; CM-20 comprised 80% natural clay and water, 18% ceramic aggregate, and 2% sugar solution; and CM-40 included 60% natural clay and water, 38% ceramic aggregate, and 2% sugar solution (1.68 M). Prepared membrane was dried at 100℃ and sintered at 1200 °C to enhance their physical, chemical, and mechanical properties. Various techniques such as X-ray diffraction, Fourier-transform infrared spectroscopy, and Dynamic Light Scattering size analysis were used to evaluate the membranes performance and efficiency. Scanning Electron Microscopy (SEM) images revealed a rough surface morphology without noticeable cracks or imperfections. Flow rate measurements using a filtration system indicated that CM-0 exhibited the highest flow rate at 110 L/m²h, followed by CM-20 at 110 L/m²h, and CM-40 at 94 L/m²h. All membranes demonstrated high removal efficiency, exceeding 99.99% for colloidal particlesfrom cosmetic products in deionized water with varying concentrations (200 PPM, 300 PPM, 500 PPM). The fouling resistance of the membrane, measured at 3.388 Pa, suggests minimal fouling, which is beneficial for maintaining consistent performance over time. The formation of fouling on the membrane surface leads to changes in pressure difference, which in turn affects the flux. It was observed that the flux decreased as a result of fouling and varying concentrations of colloidal particles used as the inlet for filtration purposes.

However, finding eco-friendly and cost-effective solutions for separating oil and water remains a challenge. To address these concerns and promote environmental health while conserving water resources, we have a cost-effective and sustainable solution that can separate oil, and recovered oil can be used in other resources, which can be used as a fuel/energy and separated water can be used in irrigation, wastewater treatment, and drinking water plants. Due to these demands, there is an urgency to adopt sustainable solutions to solve the problem of oil-water mixture. 100% cotton plain woven fabric was functionalized with ZnO nanoparticles and malic acid (MA) inspired by fish shells, demonstrating the hydrophilic properties on the fabric surface. Since malic acid contains ester group molecules, it cross-links with cotton fabric (CF) and enhances water absorption capacity. The reason behind hydrophilicity is the increasing polar group. The preparation of multi-role underwater superoleophobic cotton cloth via a simple dip coating method. Here, we successfully immobilized nanoparticles of ZnO onto cotton fabric utilizing sulfuric acid (H2SO4) as a mediating agent and coating with the help of the vacuum filter method so that nanoparticles tightly bound to the cotton fabric surface at the given required condition. subsequently anchoring withmalic acid via the dip coating method. My research has led to the creation of a novel screening charge mechanism at the fabric-oil interface, enabling efficient separation of oil-water mixtures. It is generated with the help of Caustic soda (NaOH) and some amount of anionic surfactant sodium lauryl sulfate (SLS). MA-ZnO-CF shows higher separation efficiency (>99%) and a higher underwater oil contact angle of 173˚± 1. It shows multiple properties such as self-cleaning, anti-stain, anti-oil fouling, higher separation efficiency, higher water absorption capacity, and higher water flux. The modified underwater superoleophobic cotton fabric has a high separation efficiency against a variety of oils, including hexane, toluene, and diesel engine oil.
