Visible-Light-DrivenPorphyrin/ZnO Nanohybrids forUltrasensitive Room-Temperature Triethylamine Sensing

Abstract Real-time monitoring of toxic triethylamine (TEA) at room temperature remains a significant challenge for metal oxide chemiresistors due to their typically high-power consumption and thermal requirements. This work presents a highly responsive, visible-light-activated ga...

A Blockchain-Based Tokenize–Track–Trace (3T) Architecture for Oracle-Anchored Supply Chain Traceability Using Dynamic NFTs and Smart Contracts

This paper introduces an approach based on blockchain and dynamic Non-Fungible Tokens (dNFTs) for transparent supply chain management (SCM) through end-to-end traceability and automation. The approach addresses three recurring limitations of blockchain-enabled SCM: physical-to-di...
