Enhanced thermal management and energy efficiency in electronic processor cooling using MWCNT-LA NEPCM heat sink with U-tube heat pipes S. Kalaiselvam, A. Lakshmi Kanthan Bharathi, A. Ameelia Roseline Next Energy, 2025 This study investigates the efficiency of a multi-walled carbon nanotube-infused lauric acid (MWCNT-LA) heatsink with U-tube heat pipes filled with n-pentane for electronic processor cooling. Experimental evaluations were conducted under varying heat loads and filling ratios to assess processor stability and energy efficiency. The investigation focused on energy savings, the thermal resistance of different heat pipe-assisted heatsink modules with multi-walled carbon nanotube-infused lauric acid phase change material, with its regeneration time, and optimal heat pipe filling ratio. Results showed that the MWCNT-LA heat sink module with 50% n-pentane filling performed best under higher heat loads, achieving the lowest thermal resistance of 0.63 °C/W at 50% filling ratio and 75% heat load. This design was 3.58 times more effective than the unfilled heat pipe version and achieved 78% energy savings with minimal cooling fan energy consumption. The developed heat sink design improves thermal management by utilizing latent heat storage and enhancing heat transport efficiency through the heat pipe, thus optimizing thermal performance, heat dissipation, and temperature regulation. These improvements increased the operational reliability and energy efficiency of processors in data center cooling applications. • Multi-walled carbon nanotubes embedded in lauric acid phase change material. • Nano-embedded phase change material-filled finned heat sink. • Nano-embedded phase change material heat sink increases operating time by 3.58 times. • Lower thermal resistance of 0.63 °C•W −1 at 50% filling ratio and 75% heat load. • Fifty percent is the optimum filling ratio for U-tube heat pipe.

Suitability of natural composite desiccant assisted evaporative cooling for sustainable net zero energy green building Harish Kumar U, Lakshmi Kanthan Bharathi A, Saravanan R, Kalaiselvam S Solar Compass, 2025 • Preparing organic cow dung composite desiccant. • Coating cow dung composite desiccant on wood pulp fiber paper matrix. • Evaluating DCOP, DC, and MRE of different cow dung Composite desiccant beds. • Cow dung composite desiccant performed better with 0.643 g/g of moisture uptake. • Maximum DCOP of CDC-WPFP desiccant bed is 2.52 at 50 °C regeneration temperature. This paper investigates the adsorption capacity of the organic cow dung desiccant and its composites for application as a desiccant for desiccant dehumidification systems. The composite desiccants of cow dung with calcium chloride (CDC) and with silica gel (CDS) were prepared as a solution with Hydroxyethylcellulose and coated on a Wood Pulp Fiber Paper (WPFP) substrate and their adsorption ability was studied for different temperatures (25, 35 and 45 °C) and RH (75, 85 and 95 %). The desiccant bed of size 30 × 30 cm with desiccant CD, CDS, and CDC coated on the Wood Pulp fiber paper was prepared and subjected to dehumidification and regeneration. The dehumidification capacity (DC) and dehumidification coefficient of performance (DCOP) of the CD, CDC, and CDS composite desiccant beds were analyzed. The composite CDC performed better than others with a moisture uptake capacity of 0.643 g/g by reaching saturation in 80 min. CD, CDC, and CDS desiccants show faster regeneration within 30 min at the regeneration temperature of 80 °C. The CDC-coated Wood Pulp Fiber Paper performed better and the DCOP was maximum with a value of 2.52 at 50 °C regeneration temperature considering 50, 60, 70, and 80 °C.
Investigation of TiO2 Nanoparticles Influence on Tensile Properties and Thermal Stability of Dry and Wet Luffa-Epoxy Nanocomposites K. Anbukarasi, D. Mala, N. Senthilkumar, S. Imran Hussain, S. Kalaiselvam Recent Patents on Nanotechnology, 2025 Background: Recently, progress has been made toward understanding the efficiency of polymer composites with natural fibres. With the hope of enhancing the characteristics of polymer composites supplemented with natural fibres in a watery environment, TiO2 nanoparticles have been used to improve their performance in the field. Methods: These nanoparticles were filled in luffa-epoxy components at 1, 3, and 5% volume fractions. A combination of x-ray diffraction and Fourier transform infrared spectroscopy was utilized to conduct the structural examinations. The nanoparticle spread was captured by field emission scanning electron microscopy. Results: Results show that dry nanocomposite's tensile strength and modulus have increased by 74% and, 13%, 137%, and 50% compared with epoxy and 40 vol% luffa-epoxy (E/L) composites, respectively. In wet nanocomposites, maximum reduction in tensile strength and modulus were observed as 27.4% and 16.54%, respectively. The diminished water absorption and thickness swelling percentage of nanocomposites were recorded as 98% and 91.8%, respectively. The onset temperature of these nanocomposites was scattered in the range of 379-393°C, with a maximum char residue of 38%. Conclusion: The increase in the percentage of residue indicates the effectiveness of epoxy's flame retardant, improved thermal stability, diminished water absorption (approximately 2%), and 95% retention of wet composites' tensile properties. These results provided data support for improving the application of nanocomposites in the automobile field and to develop possible patents on the new material development.
