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 […]

Inl Global Local Photonics Meetup

On November 13th and 14th, INL joined the global initiative Photonics Online Meetup (POM) as a POM-hub, bringing together 100 photonics enthusiasts from 24 organizations across Northwestern Iberia for two days of insightful discussions and engaging sessions. The conference was broadcast from the auditorium, while the lobby provided a platform for networking and socializing. The event was attended by representatives from various academic institutions, including the University of Minho, University of Porto, University of Aveiro, University of Vigo, University of Santiago de Compostela, University of Coimbra, University of Lisbon, FCT NOVA Lisbon, as well as representatives from local photonics-related industries and small and medium-sized enterprises (SMEs). There were 42 poster submissions, and the best poster prize included student registration for the conference AOP2024 and the opportunity to be featured in the program as an invited speaker, sponsored by the Sociedade Portuguesa de Óptica e Fotónica. This event was sponsored by MT Brandão Lda and Izasa Scientific.

New open-source Python tool revolutionizes design and modeling of micro optical elements | 23 August 2024

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 […]

FUNLAYERS SUMMER SCHOOL

Training on Nanoscale Characterization and Analysis + Workshop on Transferable Skills In September, FUNLAYERS promotes a four-day initiative focused on Nanoscale Characterization and Analysis.

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 […]
