Researchers from the Faculty of Chemistry and Biology successfully designed a pyridinium salt molecule that is critical for molecular electronics. The molecule's key feature is its ability to perform reversible electrical switching even when immobilized on a surface.
Chile is actively positioning itself as a global leader in green hydrogen production and export, a clean fuel that is essential for national decarbonization and reducing reliance on fossil fuels.
Thanks to its vast solar and wind energy potential, Chile is well-positioned to produce green hydrogen via water electrolysis. In this process, electricity from renewable sources such as solar panels or wind turbines is used to split water molecules into hydrogen and oxygen, producing a fuel that only emits water vapor as a waste product.
Dr. Jorge Castillo-Sepúlveda, academic at the FAHU School of Psychology and Vice Dean of Research and Postgraduate Studies, together with Jhonathan Castro Pino, are leading the cutting-edge project entitled "Towards a river biopolitics: a case study of hydroelectricity from Itaipú," funded by the Usach Office for Scientific and Technological Research through its 2025 competition.
Open science has firmly established itself as one of the most significant transformations in the global scientific system. It actively promotes the accessibility, reusability, and transparency of publicly funded research results, greatly strengthening academic collaboration and the democratization of knowledge.
Currently, this essential vision has been promoted by the National Research and Development Agency (ANID) through its Open Access Policy, which seeks to have all Chilean universities make their research publications available in interoperable repositories.
On the morning of Tuesday, November 4, the hybrid seminar “Strategies for Improving the Diet of Older Adults” was held at the Center for Postgraduate Studies and Continuing Education at the University of Santiago, Chile (USACH). The event brought together food science researchers, students, and professionals in the field of geriatric nutrition to address the critical challenges associated with improving nutrition and eating habits in older adults.
When we activate a cell phone screen, an LED flashlight, or a device that glows in the dark, the microscopic event is light emission or luminescence. This phenomenon occurs when a material absorbs energy, exciting its electrons. When these electrons return to their ground state, they release that absorbed energy, which is then transformed into light.
Renewable energy is a necessity in the face of climate change, as industries and communities are increasingly adopting clean sources, such as solar and wind power. However, a major challenge is their intermittency; the sun does not always shine, and the wind does not always blow. This variability creates a gap between when energy is generated and when it's consumed, making it difficult to use its full potential.
Dr. Ximena Rosselló Zeldis, Head of the Visual Communication Design program, recently earned her Doctorate in American Studies with highest honors. Her thesis, “Universal Design from the South: A path toward the liberation of people with functional diversity,” not only initiates a critical debate on Universal Design application in Latin America but also introduces Analectic Design—an emerging concept seeking deeply human and contextualized inclusion in the discipline.
Like forests, wetlands are critical to global health and are sometimes referred to as the planet's lungs. They provide more than just oxygen and carbon sequestration; these vital ecosystems also supply clean drinking water, act as massive carbon sinks, and shelter 40% of all species, making them essential for biodiversity.
Green hydrogen has established itself as one of the fundamental energy pillars for tackling the climate crisis and advancing global decarbonization. Unlike fossil fuels, its production is clean; when consumed in energy processes, its only by-product is water. Furthermore, hydrogen holds three times more energy than conventional fuels. Recent research indicates that hydrogen produced by electrolysis using renewable energy could reduce greenhouse gas emissions by between 50% and 90% compared to fossil fuel methods without carbon capture.
