INL advances heavy metal detection in industrial wastewater

The advances in industrial modernisation are driving research towards the development of new sensors for the Industrial Internet of Things (IIoT) or Internet of Robotic Things (IoRT), aiming to enhance efficiency, production rates, and quality standards. However, current solutions face technical limitations in accuracy, and adaptability to real-world conditions. The Next-Gen Quality Control (NGQC) IoRT project focuses on developing an automated monitoring system to detect heavy metals in industrial effluents. This ecosystem includes environmental monitoring, as well as wastewater. Pilot testing is currently underway at Stellantis in Mangualde, embracing the principles of Industry 4.0. The monitoring system is integrated into a wastewater treatment plant to understand its evolution and whether water quality limits are being exceeded. Raquel Queirós, staff researcher in the Water Quality Group, explains, “This system collects a small sample from the tank at the beginning and end of the process. This sample is then filtered to detect the presence of the heavy metals”. Samuel Silva, research fellow in the Water Quality research group, adds, “The developed electrochemical sensors have been optimised to detect nickel and zinc.” The prototype has integrated an algorithm that calculates and estimates the concentration of the heavy metals. “The system is able to […]

The magnetic world of quantum nanostructures

Over the last year, INL joined forces with Native Scientists as a partner in the educational programme “Cientista Regressa à Escola” (Scientist Returns to School). This social project, aimed at promoting scientific literacy, is truly unique and inspiring. Together, we have been able to strengthen the bond between scientists and children, inspiring the next generation and promoting equal opportunities. João Henriques, Junior Research Fellow in the Theory of Quantum Nanostructures group, visited the Escola Básica EB1/JI da Garapôa, and he described his school visit as “a wonderful experience fuelled by the genuine excitement of students eager to learn more about science”. João’s research is focused on theoretical studies of low dimensional materials, such as carbon based nanographenes. Nanographenes are fragments of graphene with unpaired electrons, which lead to magnetism. In a recently published study within the project PiMag, João Henriques and the team described the magnetic properties in these quantum nanostructures, and how it is possible to combine organic chemistry techniques to engineer new materials. The calculations provide a tuneable platform to explore quantum magnetism at the nanoscale, for potential quantum technology applications. João explains, “To explain this topic for 8-year-olds, I divided it into three parts. The first two highlighted the […]

INL hosts ASCENT+ Research Accelerator Program

In January, the INL Research Core Facilities – Micro and Nanofabrication (MNF) and Advanced Electron Microscopy, Imaging & Spectroscopy (AEMIS) – hosted a special event focused on micro- and nanofabrication, electron microscopy, and spectroscopy techniques. The event saw six participants from the ASCENT+ Research Accelerator come together for two and a half days of lectures and demos. During the event, participants were given a chance to see first-hand the different processing steps involved in microfabrication: deposition, lithography/patterning, and etching and electron microscopy and spectroscopy: SEM, FIB, XPS and TEM. The week’s highlight was an extended live demo of a microfabrication process inside the INL’s cleanroom. The INL team was pleased to share their knowledge and contribute to the training of these promising researchers. Overall, the event provided an excellent opportunity for researchers to come together and learn about the latest techniques in micro- and nanofabrication. More about the project here.

INL researchers developed an autonomous monitoring system for grape ripening

INL researchers have published a new study describing a novel prototype of a stand-alone system designed to autonomously collect grape ripening measurements. Climate change and the rapid transformation of economic value chains are driving the need for advanced decision-support systems in viticulture. The traditional method of monitoring grape maturation involves manual sampling and lab assays, but there’s a shift towards using optical techniques in agriculture. The Internet of Things (IoT) plays a key role in agriculture by connecting sensors, networks, and data processing. IoT is also one of the main drivers of precision viticulture, where the combination of multiple data sources can create complex tools for monitoring the vineyard. Hugo Oliveira, the main author of this study, explains “this IoT application involves using simplified spectral sensors to monitor grape ripening in real-time, providing analytical information about the grapes’ status. This work established the technology ground to achieve this objective”. The research work developed by INL researchers of the Systems Engineering and the Nanodevices groups, in collaboration with University of Milano, IMTEK, Sogrape, INESC-MN, and Automation, introduces a novel prototype of a stand-alone system which uses simplified spectral sensing to autonomously collect reflectance measurements directly from grape bunches. The system comprises […]
