International Day of Clean Energy—“Clean Energy: For All and for Our Planet”, 26 January 2026


26 January marks the International Day of Clean Energy, a global initiative that aims to drive equitable and sustainable energy transitions, leaving no one behind and protecting our planet. As emphasized by the UN, clean energy is essential for closing the energy access gap (an estimated 1.5 billion people in rural areas still use unsafe, unhealthy and inefficient cooking systems) and for combatting climate change (over 75% of global greenhouse gas emissions are caused by fossil fuel energy production). Clean energy fuels socio-economic progress, empowering vulnerable communities in terms of education, healthcare and livelihoods, while also addressing the issue of polluting fuels, which are linked to 3.2 million premature deaths each year.

Join us in celebrating this International Day of Clean Energy by exploring research that turns global goals, such as Sustainable Development Goal 7, into actionable solutions. Together, these works amplify the UN’s call to action, uniting researchers, policymakers, and innovators to build a future in which clean energy benefits everyone and safeguards our planet.

“Do Not Be Afraid of New Things”: Prof. Michele Parrinello on Scientific Curiosity and the Importance of Fundamental Research

In atomic and molecular simulation, researchers have long-needed efficient ways to predict material properties in order to focus on the most promising real laboratory tests instead of redundant work. Addressing this challenge, Prof. Michele Parrinello introduced two transformative methods that have redefined the field: the Car–Parrinello method, which serves as a “virtual lab” for studying reactions and electronic properties, and the Parrinello–Rahman method, a cornerstone for crystal phase transition studies. His work has reshaped the way that we study atomic systems, earning him the status of one of the most cited scholars in his field.

To honor his enduring legacy and continued impact, MDPI has established the Michele Parrinello Award. This award celebrates innovation and recognizes senior scientists who have made outstanding contributions to computational physical sciences, spanning the fields of physics, chemistry, and materials science.

We had the great honor of speaking with Prof. Parrinello in an exclusive interview, where he shared his perspectives on his current research focus, personal scientific experiences, support for basic research, and his advice for global researchers.

Access the full interview to hear his insights in this conversation.

Prof. Xin-Gao Gong Appointed Chair of the Michele Parrinello Award Committee

We are honored to announce that Prof. Xin-Gao Gong will serve as the Chair of the Michele Parrinello Award Committee.

Prof. Xin-Gao Gong is a distinguished computational condensed matter physicist and an Academician of the Chinese Academy of Sciences. He serves as a professor and doctoral advisor at Fudan University, where his groundbreaking research has profoundly advanced our understanding of material properties through computational methods. Widely recognized for his leadership in the field, Prof. Gong was elected a Fellow of the American Physical Society in 2009. He also directs the Key Laboratory of Computational Physical Sciences at Fudan University—a hub of innovation and discovery.

Under Prof. Gong’s leadership, the committee will focus on identifying innovative research in computational physical sciences, a multidisciplinary field that bridges physics, chemistry, and materials science. The committee will highlight fundamental advances with potential to drive progress across these domains, as the Michele Parrinello Award continues its mission to inspire excellence and recognize contributions that push scientific boundaries.

We recently had the honor of organizing an exclusive interview with Prof. Xin-Gao Gong. In this inspiring interview, Prof. Gong shares his academic journey from China to Italy, where he studied under the renowned Prof. Michele Parrinello and worked with one of the strongest research groups in condensed matter physics.

Prof. Gong also discusses the origins of the Michele Parrinello Award, which he proposed to honor excellence in computational physical sciences. Now chairing the award committee, he emphasizes its role in recognizing both senior researchers and inspiring young scientists to pursue innovation in fields like computational physics, chemistry, and materials science, especially in the age of AI-driven simulation.

Watch the full interview to hear his story and vision for the future of scientific excellence.
