The course went beyond writing papers and giving presentations—it was about mastering the power of storytelling, engaging audiences, and even embracing the stage! The course was split into two complementary modules: 🎤 Module 1 – “Communicating Science: Techniques for Writing and Speaking”: Led by Professor Andy Ross from Johns Hopkins University, this module helped participants sharpen their scientific writing, structure their ideas, and deliver research presentations with confidence. (January 2025)🎭Module 2 – “Stage Presence for Scientists”: Delivered by the Malad’arte Theatre Company from Braga, this module pushed students out of their comfort zones, using drama techniques to improve body language, vocal delivery, and stage confidence. (February 2025) The grand finale? “Epicenter“—a live performance, held on February 21, 2025, in which PhD students took the stage, seamlessly […]

Taking inspiration from the human brain to create a new class of intelligent, light-powered devices

At INL, our researchers are pushing the boundaries of brain-inspired computing, developing neuromorphic systems that process sensory data the way nature does – fast, efficiently, and with minimal energy. In a recently published paper in Scientific Reports, INL researchers developed a tiny micropillar quantum resonant tunnelling diode, or RTD, that behaves like a sensory neuron. This ‘neuron’ is capable of detecting light, processing information, and converting it into electrical signals, all within a single nanoscale device. Researcher Bruno Romeira explains, “This is possible because we are using quantum phenomena.” At its core, this system is a III–V semiconductor structure (materials widely used in photonics and high-speed electronics) designed to respond directly to incoming near-infrared light. When the light intensity reaches a certain threshold, the device enters a state known as negative differential resistance, triggering large-amplitude voltage oscillations. In other words, the incoming light signal is transformed into rhythmic electrical bursts, just like the firing patterns seen in biological neurons. Traditional neuromorphic hardware often relies on complex circuits, combining separate memory components and oscillators to mimic the way biological neurons process information. This increases the size, power consumption, and complexity of the system. The new device developed by Bejoys Jacob and […]

INL Develops High-Speed Nanosecond True Random Bit Generator for Secure Computing

The International Iberian Nanotechnology Laboratory (INL) has developed a Nanosecond True Random Bit Generator (nRBG), on an advanced solution for secure randomness in cryptographic systems, artificial intelligence (AI), and high-performance computing (HPC). The nRBG technology operates at the nanoscale and delivers true random numbers at a speed of one bit every 10 nanoseconds, making it one of the fastest and most reliable random number generation solutions available today. Its high entropy and unpredictability have been validated through 10 National Institute of Standards and Technology (NIST) randomness tests, ensuring its suitability for critical security applications. Advancing Computing with True Randomness Random number generation is a fundamental component of digital systems, particularly in encryption, communications, and AI-driven models. Unlike other generators, which rely on deterministic algorithms, INL’s nRBG generates unpredictable, high-speed random bit streams, enhancing efficiency across various domains. Key features of INL’s nRBG include: Potential Applications: INL’s nRBG is designed to support a range of high-security and computational applications, including: INL partners with technology companies, research institutions, and industry leaders to explore: technology integration – embedding the nRBG into existing and emerging security architectures; joint research and development (R&D) – advancing next-generation randomness solutions for AI, quantum computing, and cybersecurity; and commercialisation pathways – bringing nRBG technology to market-ready applications. Organisations interested in integrating nRBG […]

Can Earth’s gravitational field monitor climate change?

The measurement of our planet’s gravitational field, known as gravimetry, allows us to extrapolate the rate at which climate changes are occurring by detecting small variations in Earth’s gravitational field, caused, for example, by melting ice. Inês Sofia Garcia, a Research Engineer at INL, is focused on the development of a high-precision MEMS (micro electromechanical system) accelerometer, crucial for detecting the gravity field shifts of our planet. This accelerometer is a system capable of converting a mechanical phenomenon into an electrical one, and vice versa, transforming an electrical signal into a mechanical displacement. “Our group is creating a MEMS accelerometer to measure Earth’s acceleration changes,” explains Inês Garcia. “We handle the system’s modelling, design, fabrication, and characterisation.” With rigorous demands for stability, power management, and satellite orientation accuracy, this research work strengthens Portugal’s position in the global space sector. The team developed the device as part of the uPGRADE project, and at INL, we are already looking ahead to its next phase: uPGRADE-NEXT. In this new project, the device will undergo space qualification and is set to be included in the first uPGRADE microsatellite launch, planned for mid-2026. These flagship projects, led by Rosana Dias and Filipe Alves, will also […]
