Unraveling the Excited State Proton Transfer Mechanism of Salicylamide: A TD ‐ DFT Study

ABSTRACT Excited‐state proton transfer (ESPT) plays a crucial role in photochemical processes, serving as an important mechanism for modulating molecular structures and fluorescence behaviors. In this study, the ESPT mechanism of salicylamide (SAM) was systematically investigated...

Characterization and molecular dynamics of interfacial adhesion in hydrogenated styrene/polyurethane prepolymer composite-modified asphalt

To address the limitations of conventional polymer modified asphalt, a hydrogenated styrene block polyurethane prepolymer (M-PPU) modified asphalt was developed by incorporating a hydrogenated styrene block into a polyurethane prepolymer (PPU). The preparation process was first o...

Anti-Disturbance Dynamic Memory Event-Triggered Control for Robotic Manipulator Systems

This study investigates the H∞ anti-disturbance dynamic memory event-triggered (ADDMET) control issue for Robotic Manipulator System (RMS) under multiple disturbances. An affine model is adopted to characterize the RMS, accounting for payload variations and complex operating cond...

Lightweight design methodology for marine rotating machinery: Co-design of equivalent material parameters and structural performance in lattice-architected impellers

This study presents a material-structure co-design framework for lightweight lattice-architected impellers targeting marine propulsion applications. By replacing explicit micro-scale lattice modeling with equivalent material parameters (density, elastic modulus, Poisson’s ratio),...

Recent Advances in Perovskite-Based Gas Sensors: Material Design, Fabrication Strategies, Sensing Mechanisms, and AI-Assistance

Perovskite materials have emerged as promising candidates for gas sensing owing to their tunable structures, adjustable compositions, rich defect chemistry, and efficient charge transport properties. These characteristics enable the effective regulation of active sites, oxygen va...

Dynamic Total Cost of Ownership Assessment of Methanol Dual-Fuel Container Ships in the Ningbo–Zhoushan–Valencia Green Shipping Corridor

Green methanol is widely regarded as a technically feasible low-carbon marine fuel for sustainable shipping in the medium term, but its economic viability remains constrained by fuel price and supply-scale uncertainty. This study develops a dynamic total cost of ownership (TCO) m...

Optimising maritime logistics to island ports using Max-Flow and Traffic modelling

Efficient maritime logistics between mainland ports and island destinations is essential for trade and regional integration in East Africa. This study develops a sequentially coupled optimisation framework for cargo movement from Dar es Salaam to Zanzibar, Comoros, and Seychelles...
