Engineering Carbon Dots as Multifunctional Nanomaterials

Carbon dots (CDs) represent an emerging class of carbon-based nanomaterials. With size below 10 nm, CDs present the unique combination of photophysical properties, tunable surface chemistry, and biocompatibility that make them highly adaptable platforms for addressing challenges in diverse scientific and technological domains. Advances in synthetic strategies, including both pre- and post-synthetic design, now allow precise tailoring of their structure-function relationships, enabling the...

Hydrogen and Oxygen bubble detachment from nanowire-based electrode in alkaline electrolyzers

Green hydrogen is one of the most promising solutions for integrating renewable energy so urces, allowing excess energy to be stored and used when needed. Green hydrogen can be used in various sectors, from industry to transport. However, its main drawback remains the high cost compared to hydrogen produced from fossil sources. Many studies foc us on optimizing electrolysis technology to reduce costs and improve efficiency. An efficient way to improve the performance of electrolysis is ...

Optimizing CVI-based heuristic approach for regional coastal vulnerability assessment in Sicily and 2000-2019 shoreline change calibration

Coastal vulnerability can be defined as its proneness to be damaged by changing climatic and/or geomorphic conditions. In this study, coastal vulnerability focuses entirely on the physical impact of erosion, distinguishing the coastal behaviour between negative (susceptibility) and positive (resilience) responses to climate change-induced conditions, without taking into account any socioeconomic variables. The Coastal Vulnerability Index (CVI) approach has become one of the most used and...

Hydromorphological Quality Index assessment and sensitivity analysis: a test in north-western Sicily

IDRAIM (System for Stream Hydromorphological assessment, analysis, and monitoring) is the multiparametric expert based approach for assessing the ecological status of the Surface Water Bodies (SWBs), which has been formally adopted by the Italian Institute for Environmental Protection and Research and explicitly included in the national technical standards. In the framework of a collaboration between the University of Palermo and the Basin Authority of the Sicilian Region, an approach has be...

Emilia-Romagna, Italy: could the landslide phenomena of May 2023 have been predicted?

In May 2023, the Emilia-Romagna region (Italy) was hit by intense rainfall, causing significant economic damage (8.6 billion euros) and 17 fatalities. After a prolonged dry period, with only occasional light precipitation, two major rainfall events occurred on May 1 st - 3 rd and May 16 th -17 th , bringing cumulative precipitation exceeding 500 millimetres in various locations. The Emilia-Romagna Region reported 80,946 landslides triggered by these rainfall events, many of which d...
