INL team develops sensor to detect multidrug-resistant bacteria

A research team at INL is using ionizing light to “smell” volatile compounds emitted by multidrug-resistant bacteria. Antibiotic resistance is a serious global threat with widespread implications, contributing to an estimated 5 million deaths annually due to drug-resistant infections. This occurs as bacteria evolve to resist the effects of antibiotics, leading to new bacterial strains that are resistant to treatment. As a result, infections become harder to treat, increasing the risk of disease spread, severe illness, and death. Recently, this work was featured in ‘90 Segundos de Ciência’, a series of science communication episodes with daily broadcasts on Antena 1 Portuguese public radio. In this episode, Research Engineer Susana Costa explains INL’s contribution towards this exciting project in just 90 seconds (in Portuguese). The novel sensor is being designed to detect multidrug-resistant bacteria in hospital environments and healthcare facilities. Susana Costa explains that “the photo-ionization sensor employs a sophisticated mechanism that emits light, targeting gaseous molecules released by bacteria present in the air. When the light interacts with these molecules, it ionizes them, creating ions and electrons. These electrons, under the influence of an electric field, generate an electric current, which is then measured by the system”. The technology behind […]

September 20, 2024, Government Declares National Day of Mourning for Fire Victims

The Portuguese Government has declared a National Day of Mourning for Friday, September 20, 2024, to honour the victims of the devastating wildfires that swept through the North and Central Portugal earlier this week. The announcement was made today by António Leitão Amaro, the Minister of the Presidency. This day of national mourning reflects the profound sorrow and solidarity of the Portuguese people in the wake of these tragic events. “On behalf of the government and the nation, we express deep regret for the loss of lives and the devastating impact of the fires,” said Leitão Amaro. “Our hearts go out to the families of the victims, and we stand united with them in their grief.” The fires, which have claimed lives and left several injured, tore through rural and forested areas, leaving destruction in their wake. Several towns and villages were severely affected, with homes, businesses, and farmlands reduced to ashes. While thousands of residents have been evacuated, many remain displaced as emergency services work tirelessly to bring the situation under control. Over the past week, the combination of intense heatwaves and strong winds fuelled the fires, making them extraordinarily difficult to contain. Portugal’s emergency response was further challenged […]

Nanotechnology as a strategy for plastics in a circular economy

In a world increasingly conscious of environmental impact, industries that rely heavily on plastic materials face significant challenges. Plastics can be found in everything from packaging to consumer electronics. However, the environmental consequences of plastic waste are driving the sector towards a much-needed transformation. The European strategy for plastics in a circular economy embraces an ambitious approach to enhance the recyclability of plastic packaging and provides a strong response to the issue of microplastics, a major contributor to marine pollution. The current design, production, use, and disposal of plastics have harmful effects on our society, economy, and environment. Supported by the EU, projects such as FlexFunction2Sustain and Convert2Green are creating a sustainable open innovation ecosystem. This ecosystem helps small industries bring innovative products to market faster, with a focus on new polymer formulations, such as bio-based and biodegradable plastics. INL researcher Victor Souza explains that their lab is developing “sustainable, smart products that can drastically reduce the environmental footprint of industries that rely on plastics.” The goal is to make these materials both high-performing and eco-friendly. Pastrana’s group is addressing the challenge of plastic waste by developing nano-functionalised flexible plastic and paper materials. Victor explains, “At INL, we are working […]

Revolutionising micro optics: INL researchers develop open-source software for advanced design and modelling

INL researchers, in collaboration with Bosch Car Multimedia and Bosch Security Systems, recently published an article on Computer Physics Communications, where they introduce a new open-source Python software that democratises the design and modelling of micro optical elements and flat optics. Micro optics can replace bulky traditional optics with sleek, micro and nanostructured alternatives, enabling more advanced optical functions. These components, produced with semiconductor microfabrication techniques, require precise binary or multilevel lithography masks to translate computed designs into physical components. However, no existing tool offers a complete solution for designing, simulating, and generating these masks – until now. INL researchers developed an open-source software package to fill this gap, by providing an end-to-end solution that allows users to design, simulate, and generate lithography masks for micro optical elements. João Cunha, a Marie Skłodowska-Curie Postdoctoral Fellow at INL, explains “with this new development it is possible to create masks directly from your desired optical functions, and export them as binary or multilevel lithography files (such as GDSII and DXF) compatible with standard microfabrication tools.” “This package addressed the challenge of producing surface relief diffractive optics by discretisation of continuous topographies into mask layers, required for specific micro and nanofabrication approaches, such […]

Advanced electron microscopy to investigate magnetic layered materials

In a recent study published in Nature Communications, INL researchers Loukya Boddapati and Francis Leonard Deepak, along with an international team from Korea, Spain, the U.S., and the U.K., used cutting-edge electron microscopy, including low-temperature Cryo-TEM, to explore the structural phase transitions of CrI₃. CrI₃ is a novel magnetic material which has attracted significant attention for its unique ferromagnetic properties and potential applications in spintronics. The stacking configurations in van der Waals crystals significantly influence several material properties. Previous research has shown that stacking engineering is a powerful method for achieving desired properties through layer-by-layer crystal engineering. Controlling the twist angle between artificially stacked two-dimensional (2D) materials has led to the discovery of unconventional phenomena, ranging from superconductivity to strongly correlated magnetism. This study clarifies the complex relationship between these transitions and the material’s magnetic properties. In this study, cross-sectional TEM analysis was used to identify interlayer stacking disorders in CrI3. According to Francis Leonard Deepak, “the study provides evidence of twisted stacking faults in CrI₃ and reveals changes in the relative population of twisted domains, without the anticipated transition to the rhombohedral phase at low temperatures”. “These findings underscore the importance of understanding layer-dependent stacking order and magnetic properties […]

Researchers achieve quantum breakthrough with novel quantum-to-quantum Bernoulli factory design

Unlike classical computers, which use bits to process information as either 0s or 1s, quantum computers use quantum bits, also known as qubits, which can represent and process both 0 and 1 simultaneously thanks to a quantum property called superposition. This fundamental difference gives quantum computers the potential to solve some complex problems much more efficiently than classical computers. INL researcher Ernesto Galvão, in collaboration with Sapienza Università di Roma (Rome) and Istituto di Fotonica e Nanotecnologie (Milan), recently published a groundbreaking study in the journal Science Advances, where they describe a new set-up for a quantum-to-quantum Bernoulli factory. A Bernoulli factory is a method to manipulate randomness, using as inputs random coin flips with a certain probability distribution, and outputting coin flips with a different, desired distribution. Let us imagine we have a coin that lands on heads with some unknown probability. Now, we want to create a new coin that lands on heads with a different probability, possibly described by a function of the initial probability. The Bernoulli factory is an ingenious way to flip our original coin multiple times and use the different outcomes to simulate the new coin with the desired probability. Ernesto Galvão adds “This […]
