Purpose Public transportation plays a crucial role in reducing traffic congestion, greenhouse gas emissions, and social inequalities in urban systems. However, selecting the most sustainable transit bus technologies remains challenging because socio-economic conditions, geographic characteristics, and energy infrastructures vary across regions. This study aims to develop an integrated sustainability-based decision-making frame...

Single-walled carbon nanotubes (SWCNTs) that emit fluorescence in the near-infrared region (NIR) enable the identification of certain molecules as a result of surface modification. In this study, a selective sensor system against dopamine, a neurotransmitter, was developed by wrapping a Guanine-Thymine-Adenine (GTA) 20 -repeat single-stranded DNA structure around SWCNT. Sensor analysis fluorescence measurements in the NIR regi...
