Chemists create light-switchable magnets that remain active for hours

 



Chemists have achieved a groundbreaking advancement in materials science by developing light-switchable magnets that can remain active for hours. This innovative class of magnetic materials is engineered to respond to light, offering a controllable and reversible way to manipulate magnetism without the need for constant external power sources. Traditional magnets rely on intrinsic atomic structures to maintain magnetic order, but these new photo-responsive magnets harness molecular-level design and light-induced electronic changes to achieve long-lasting magnetic states.

The principle behind this innovation involves embedding photosensitive molecules into specially designed frameworks. When exposed to light of a specific wavelength, these molecules undergo structural and electronic transitions, which trigger and stabilize magnetism within the system. Unlike earlier attempts where light-induced magnetism quickly faded, this new approach allows the magnetic state to persist for hours even after the light source is removed. Such durability opens the door to more practical applications, including low-energy data storage, reconfigurable electronic circuits, and advanced quantum technologies.

One of the most promising aspects of this discovery is its potential role in sustainable energy and computing. Since the magnets can be activated and deactivated using light, they drastically reduce energy consumption compared to conventional electrically powered systems. Additionally, the switchability feature makes them highly suitable for use in spintronics, where the control of electron spin is crucial for next-generation devices. In medicine, light-switchable magnets may pave the way for targeted drug delivery, controlled release systems, or even non-invasive diagnostic tools.


This breakthrough represents a fusion of chemistry, physics, and materials engineering, highlighting how interdisciplinary research can unlock new frontiers in technology. While challenges remain in scaling up production and improving stability across various environmental conditions, the progress marks a significant milestone. The creation of light-switchable magnets that remain active for hours not only demonstrates a leap forward in molecular magnetism but also signals a future where smart, energy-efficient, and light-controlled devices could become part of everyday life.

Does AI pose a threat to sustainable development?

Image
  The 2025 World Economic Forum, being held in Davos from Monday to Friday under the theme " Collaboration for the Intelligent Age ", is expected to foster a spirit of cooperation and optimism in the digital age in a more sustainable way, despite the different positions of the participants and global uncertainties. Three experts share their views on the issue with China Daily. Projected estimates indicate that advanced artificial intelligence (AI) systems will necessitate over $1 trillion in investments for cloud and enterprise data center infrastructure within the next five years. The AI infrastructure includes servers equipped with graphics processing units (GPUs) or custom accelerators, dedicated networks, storage solutions and specialized facilities, which are all factors that demand significant capital investment. Therefore, evaluating the scale, potential returns and environmental impact of AI's rapid development and application is essential. The rise of AI will si...

Building urban resilience to climate change

Image
  Building Urban Resilience to Climate Change is an essential framework for cities to safeguard their infrastructure, ecosystems, and populations from the increasing threats of climate change. As urban areas grow and climate impacts intensify, it's crucial to develop adaptive measures that not only reduce vulnerabilities but also promote sustainable urban development. This approach involves a variety of strategies, including enhancing green infrastructure, improving water and energy management, promoting low-carbon transportation, and integrating climate adaptation into urban planning. Urban resilience focuses on creating systems that are both adaptable and responsive to climate stressors like heatwaves, flooding, and storms. By prioritizing nature-based solutions such as urban parks, green roofs, and wetlands, cities can mitigate heat island effects, improve air quality, and protect biodiversity. Moreover, integrating sustainable architecture, resilient infrastructure, and effici...

'Our model of cosmology might be broken': New study reveals the universe is expanding too fast for physics to explain

Image
 A recent study has revealed a puzzling discrepancy in our understanding of the universe’s expansion rate, suggesting that our current cosmological models may need a significant overhaul. The crux of the issue lies in the Hubble constant (H₀), a measure of the universe's expansion rate, which appears to differ depending on how it is calculated. For decades, scientists have relied on two primary methods to determine H₀. The first involves observing the cosmic microwave background (CMB), the faint afterglow of the Big Bang, and extrapolating the universe's expansion rate using early-universe physics. The second method uses the local universe, measuring distances to nearby galaxies via "standard candles" like Cepheid variables and Type Ia supernovae. However, these two methods yield conflicting results. The CMB method, based on data from missions like Planck, estimates H₀ to be around 67.4 kilometers per second per megaparsec (km/s/Mpc) . In contrast, local measurements...
