The Value Chain of Sustainable Dual Carbon Sodium Ion Capacitors

open access: yesBatteries &Supercaps, Volume 8, Issue 8, August 2025.
Sodium‐ion capacitors (SICs) bridge the energy‐power gap between batteries and supercapacitors, offering sustainable and scalable energy storage solutions. This review provides a 360‐degree perspective on SIC technology, covering material choices, presodiation strategies, manufacturing challenges, applications and life cycle assessment to ensure ...

AI‐Powered Advancements in Food Analysis and Safety: Ensuring Quality, Protection, and Precision in Modern Food Systems: A Review

open access: yeseFood, Volume 6, Issue 4, August 2025.
The role of AI in contaminant detection and spoilage prediction is underlined. One of the applications is using near‐infrared spectroscopy on a machine learning algorithm sample to determine if it contains any adulterants in olive oil. Also, trying to develop computer vision techniques that can soon be widely deployed to detect defects in the automated

Effects of Cosmic String Velocities and the Origin of Globular Clusters

open access: yes, 2015
With the hypothesis that cosmic string loops act as seeds for globular clusters in mind, we study the role that velocities of these strings will play in determining the mass distribution of globular clusters.
