Poly-Sorb: Synthesis of Waste-Derived Polysulfide Sorbents for Oil Spill Recovery and Environmental Remediation
Authors: Osorio Lolo iii, Daniel Adrian Labadan, Ginrie P. Villaruel, Kathrina Clariss P. Duliente, Jesson H. Cinto
Abstract: This study utilized sulfur, waste cooking canola oil (WCCO), and sodium chloride, a waste-derived polysulfide sorbent synthesized for potential use in oil spill recovery and remediation. Through thermal copolymerization at 170°C , washed, and dried. Three concentrations were produced (15–15–70, 20–20-60, and 25–25–50 wt%). Oil absorption capacity, reusability retention across three cycles, and oil removal efficiency were tested for the three concentrations of polysulfide sorbent. Based on the findings, all concentrations showed successful results in absorbing oil, with 15-15-70 wt% achieving the highest mean absorption (1.42 g/g) and reusability retention (38.73%). 25-25-50 wt% performed the highest in terms of oil removal efficiency (96.0%), followed by 15-15-70 wt% (95.0%). Among three different concentrations, one-way ANOVA showed no statistically significant difference at α = 0.05 in terms of absorption capacity. The polysulfide sorbent showed effective absorption, moderate reusability, and high removal efficiency generally, indicating for its potential as a low-cost and eco-friendly sorbent. To help improve durability and performance, enhancement and conducting extended testing under simulated environmental conditions are recommended for future studies.

Cybersecurity Challenges In IoT-Enabled Supply Chains
Authors: Dr Anuranjita Dixit
Abstract: IoT has disrupted supply chains worldwide by incorporating smart sensors, RFID tags, cloud-based visibility systems, autonomous tracking devices, robotics, and data-driven logistics. IoT-SC provides considerable operational benefits, including real-time tracking, predictive maintenance, inventory automation, transportation optimization, and responsive decision-making. However, it simultaneously brings in serious cybersecurity challenges due to the distributed nature of IoT ecosystems, resource-constrained devices, heterogeneous communication protocols, and exposure to public networks, vulnerabilities in every supply chain layer-from procurement and manufacturing to warehousing, distribution, and last-mile delivery.This research paper will comprehensively analyze the threats, vulnerabilities, and risks in IoT-enabled supply chains in regard to cybersecurity. It reviews the existing literature, maps attack surfaces, and evaluates major cyberattacks affecting supply chain IoT infrastructure, such as malware propagation, DDoS attacks, side-channel attacks, data tampering, firmware manipulation, RFID spoofing, GPS jamming, and supply chain infiltration via compromised vendor devices. The paper will also propose a multi-layer security framework for IoT-based supply chains that includes device authentication, lightweight encryption, blockchain-based integrity, intrusion detection systems, AI-driven anomaly detection, ZTA, and post-quantum cryptography.The goal is to emphasize the importance of robust cybersecurity strategies that would effectively protect IoT-enabled supply chains against emerging threats without compromising efficiency, scalability, and interoperability. The paper concludes with some future research directions, emphasizing dynamic security adaptation powered by AI, threat simulation using digital twin concepts, and advanced cryptographic techniques appropriate for next-generation IoT ecosystems.

FOOTSTEP POWER GENERATION
Authors: Aditya Kale, Srushti Dani, Sonali Gawali, Om Menkudle
Abstract: In last few years low power electronic devices have been increased rapidly. The devices are used in a large number to comfort our daily lives. With the increase in energy consumption of these portable electronic devices, the concept of harvesting alternative renewable energy in human surroundings arises a new interest among us. In this project we try to develop a piezoelectric generator. That can produce energy from vibration and pressure available on some other term(Like people walking ). This project describes the use of piezoelectric materials in order to harvest energy from people walking vibration for genera ting and accumulating the energy. This concept is also applicable to some large vibration sources which can find from nature. Thisproject also represents a footstep of piezoelectric energy harvesting model which is cost effective and easy to implement.

Voice And Text Based Chatbot
Authors: Zaibindah Rafeeq Pandit, Sabit Aslam, Rehana Jan, Irfan Rasool
Abstract: Conversational agents, or more popularly called virtual assistants or chatbots, are now a unifying interface for modern digital ecosystems, enabling seamless human-computer interaction. Fueled by unprecedented accelerations in Artificial Intelligence (AI), Machine Learning (ML), and Natural Language Processing (NLP), these agents evolved from script-based rules to sentient agents with the capability to understand context, sentiment, and intent. Transformer-based models such as GPT and BERT have significantly improved fluency, coherence, and chatbot response flexibility so that conversations could be more human-like. The present paper follows the historical progression of conversational agents from the initial symbolic systems such as ELIZA to modern-day deep learning models. It covers significant architectural components like intent recognition, conversation management, and response generation with emphasis placed on the intersection of speech-to-text (STT) and text-to-speech (TTS) for voice interaction. The book also looks into popular frameworks and toolkits used to develop and deploy chatbots into real-world applications across healthcare, education, customer support, and mental health. Moreover, the paper highlights major challenges hindering the robustness of current systems, including data bias, hallucination, context limitations, and lack of emotional intelligence. Moral implications—particularly of fairness, privacy, and explainability—are argued against in terms of novel guidelines and mitigation strategies. A modular, LLM-assisted architecture is suggested to demonstrate practical implementation with inherent evaluation metrics. Finally, the paper outlines guidance for subsequent research and development, calling for emotionally smart, multi-lingual, and culturally sensitive conversational agents that are ethics-compliant and highly accessible and performing.

Mealsphere Management System
Authors: Durgesh Nishad, Purvesh Patil, Vedant Chaudhary, Ghansham Bordekar, Dr.Umesh Pawar
Abstract: The MealSphere Management System is a modular, automated platform designed to streamline food ordering, inventory tracking, billing, and administrative operations. Traditional restaurant workflows reliant on handwritten logs and disconnected tools often result in delays, errors, and poor visibility. MealSphere resolves these inefficiencies through a centralized system that integrates authentication, menu management, inventory deduction, digital billing, and analytics. It supports both offline and online modes, ensuring operational continuity and real-time synchronization. This paper presents the system’ s architecture, implementation, and performance evaluation, demonstrating its scalability across restaurants, hostels, cloud kitchens, and canteens.
AIRMATH: FULLY AUTOMATIC SOLAR CRASS CUTTER
