    Green Grafting Innovations in Polymer Functionalization for Sustainable Solutions in Pharmaceutical and Healthcare Industry Part 2, 2026
    In biomedicine, the biocompatible and good physical and chemical properties of polyurethanes are frequently employed in medical devices, such as coronary stents. Despite being a perfect tissue frame in many ways, polyurethane exhibits better compatibility than other polymers, which can be partly attributed to its surface characteristics. Here, we outline a process for functionalizing polyurethane gallows that entails integrating. The primary amine groups thus inserted into the polyurethane surface enable further coupling with dextran and recombinant peptides through reductive amination. Surface analysis is used to confirm the effectiveness of surface functionalization of an aliphatic poly(ether)urethane of medical grade. Polymers are so lightweight, moldable, and adaptable that they are indispensable in modern life; as a result, the human population grows, so will the need for polymers. During their usage, structural and functional polymers save CO2 and have benefits for sustainability; yet, they pose problems when they reach the end of their useful lives. By utilizing the most recent developments in the field, polymer science and related fields can facilitate the circular economy of polymers by means of biodegradation or recycling. This can be achieved through the implementation of techniques for molecular and system design. Computational material science and advances in polymer chemistry and applications pave the way for a comprehensive approach to resolving these concerns through the design of materials that are biodegradable and recyclable. For applications involving controlled medication release, biodegradable polymers can be employed. They break down naturally in the body to produce non-toxic metabolites.
  • A comprehensive acoustic analysis of a single expansion chamber reactive muffler
    Shravani Kulkarni, Mahesh Kulkarni, Deepak Hujare
    Building Acoustics, 2025
    This study explores the acoustic performance of a single-expansion-chamber reactive muffler through theoretical, numerical, and experimental methods, focusing on transmission loss as a measure of noise attenuation. Theoretical analysis employs the Transfer Matrix Method (TMM) to model the sound wave behavior by incorporating geometric parameters and fluid acoustic properties. Numerical simulations using the Finite Element Method (FEM) provide insights into the sound pressure distribution and validate theoretical predictions. Experimental testing in a controlled laboratory environment measures the muffler transmission loss and offers a practical benchmark for comparison. The results revealed a strong correlation between the theoretical, numerical, and experimental data, demonstrating the reliability of these methods. This study identifies critical design parameters that influence noise attenuation and provides guidelines for optimizing muffler performance in automotive applications. This integrated approach offers a comprehensive framework for analyzing and improving the acoustic efficiency of reactive mufflers.

    Journal of Engineering and Applied Science, 2025
    The verification of mathematical models for multistage reciprocating compressors is crucial for ensuring their accuracy and reliability. In this study, we used different machine learning (ML) models to verify the results of MATLAB-based models of single-stage reciprocating compressors, multistage reciprocating compressors without intercoolers, and multistage reciprocating compressors with intercoolers to simulate the real-world operating conditions of a reciprocating compressor. The verification focuses on key performance indicators, such as the pressure–volume (PV) graph, outlet temperature graph, volumetric efficiency, and pressure ratio graph. The MATLAB model computes thermodynamic parameters, such as the power required, outlet pressure, and outlet temperature for various operating conditions. The MATLAB model produced the following results for single-stage compressor: the outlet pressure increased by 1.6 times the inlet pressure of the compressor, the volume reduced by 20% of the volume at the inlet of the single-stage compressor, and the outlet temperature increased by 30% of the inlet temperature. In the case of a multistage compressor without an intercooler, the outlet pressure increased by about 3.3–3.6 times the inlet pressure of the compressor; the volume reduced by 60% of the volume at the inlet, and the outlet temperature increased by 35% in comparison to the inlet temperature of the multistage compressor without an intercooler. Subsequently, in the case of a multistage compressor with an intercooler at the first stage of compression, the pressure increased by three times the inlet pressure; at the second stage of compression, the pressure increased by six times the inlet pressure of the compressor, the volume was reduced by approximately 80%, and the intercooler maintained the increase in outlet temperature by 30%, limiting it and preventing excessive expansion of air in the compressor and increasing the efficiency of the compressor by 12% in comparison to the multistage compressor without an intercooler. In addition, the results generated by all the machine learning models used in the study were in correlation with the results generated by the MATLAB model for all three compressors, with an accuracy of approximately 90% or more for almost all the models implemented for prediction. By comparing the predicted outputs from the ML model with the MATLAB-generated results, the accuracy and consistency of the simulation were assessed. This study aims to bridge the gap between traditional mathematical modeling and modern data-driven validation techniques to ensure robustness in compressor performance predictions.

    SAE Technical Papers, 2024
    <div class="section abstract"><div class="htmlview paragraph">Dimensional optimization has always been a time-consuming process, especially for aerodynamic bodies, requiring much tuning of dimensions and testing for each sample. Aerodynamic auxiliaries, especially wings, are design dependent on the primary model attached, as they influence the amount of lift or reduction in drag which is beneficial to the model. This study aims to reduce the time period taken to finalize the design parameter for the same. For a wing, the angle of attack is essential in creating proper splits to incoming winds, even under high velocities with larger distances from the separation point. In the case of a group of wings, each wing is then mentioned as a wing element, and each wing is strategically positioned behind the previous wing in terms of its vertical height and its self-angle of attack to create maximum lift. At the same time, its drag remains variable to its shape ultimately maximizing the C<i><sub>L</sub></i>/C<i><sub>D</sub></i> ratio. A high value of C<i><sub>L</sub></i> indicates a significant component of horizontal drag is converted into a vertical lift. While the value of C<i><sub>D</sub></i> remains variable to different design factors, adjusting the angle of attack can minimize the drag forces caused by reducing the frontal area of impact. In this study two winged elements were considered for the front wing. Three parameters with 5 levels each were used for the parametric optimization. Twenty-five sets of setup designs were considered as a part of the Taguchi optimization study. The <i>C<sub>L</sub>/C<sub>D</sub></i> ratio of X<sub>5</sub> model obtained by CFD analysis is 15.78 and by experimental testing is 15.32. It is found that the <i>C<sub>L</sub> /C<sub>D</sub></i> ratio obtained by Numerical analysis and Experimental investigation are well corroborated.</div></div>
  • Characterization and In-vitro Study of Polyethylene Glycol as Coating Material used as Drug Carriers on Coronary Stent for Treatment of Cardiac Diseases
    Jayashri V Chopade, Deepak Hujare
    International Journal of Drug Delivery Technology, 2024
    Background: The way coronary artery disease is treated has changed dramatically with the use of coronary angioplasty and stenting. Nowadays, acute coronary syndromes brought on by coronary artery disease are frequently treated using drug-eluting stents. A review of the literature reveals that the polymer coating’s thickness affects the stent’s safety; moreover, current computational studies suggest that larger coatings increase the risk of stent deformity. Polyethylene glycol is the preferred polymer coating material for coronary artery stents.Objectives: Characterization of polyethylene glycol as a medication carrier coating for coronary stents used in cardiac disease therapyMethods: Using UV-visible spectrophotometer, differential scanning calorimetry (DSC), fourier-transform infrared (FTIR), X-ray diffraction, thermogravimetric analysis, and surface morphology, polyethylene glycol was characterized.Results: The calibration curves’ linear regression results, as revealed by the UV-visible spectrophotometer investigation, showed a significant linear association between the concentration range of 10 to 60 μg/mL for polyethylene glycol Y = 0.0354X + 0.0212 (r2 = 0.999), was found. Polyethylene glycol’s molecular miscibility, recrystallization, and phase separation were investigated using a DSC analysis. It was found that the material was physically stable because no recrystallization peaks were visible. According to the results of the thermogravimetric study, a ceramic sample cup with 4 to 6 mg of sample was heated to 400°C at a rate of 5°C every minute. Nitrogen gas was continuously supplied at a rate of 20 mL/min into the sample chamber during the analysis. The results of each batch were measured, and an average was determined. The study of surface coatings to examine the microstructure of the coatings produced both before and after the use of polymers is known as surface morphology. Within analytical imaging is the subset of surface morphology. Pure polyethylene glycol’s morphology showed broad plate-shaped structures. Additionally, a strong band is detected between 1362 and 1287 cm-1, which is comparable to the C-O stretching vibration seen in primary alcohol.Conclusion: On base of the characterization results above shows that polymers were stable and included functional groups and structures throughout a range of conditions. It is possible to use polyethylene glycol as a coating material for coronary stents.
