In the realm of photocatalysis, the efficient transfer of energy is paramount. Recent advancements by Dr. Albert Solé-Daura and Prof. Feliu Maseras have unveiled groundbreaking applications of the Marcus theory, historically known for its role in modeling electron transfer processes. Their innovative approach leverages this theoretical framework to elucidate the energy transfer (EnT) mechanisms, specifically
Samarium (Sm), a member of the rare earth metals, has garnered attention from organic chemists due to its unique ability to facilitate single-electron transfer reductions through its divalent compounds. Among these, samarium iodide (SmI2) stands out due to its moderate stability and versatility, allowing reactions to occur under mild conditions and at room temperature. This
Histones are widely recognized as vital proteins that play a foundational role in the life of complex organisms by structuring and compacting DNA. Traditionally, these proteins have been associated with eukaryotic organisms—the multicellular entities like plants and animals—leading to the perception that simpler forms of life, such as bacteria and archaea, lacked such advanced mechanisms
When we think of crystals, our minds might conjure images of beautiful gemstones or artificial ones created in laboratories. Yet, surprisingly, a variety of living organisms—ranging from graceful fish to adaptable chameleons and industrious crabs—also produce crystals. However, whereas these organisms utilize crystals for beneficial purposes such as vision and camouflage, others like the character
Cholesterol is often vilified for its association with heart disease, yet it is an essential molecule that plays a pivotal role in the structural integrity and functionality of cell membranes. Recent research from Rice University, spearheaded by Professor Jason Hafner, sheds light on this complex molecule and its interactions within biomembranes. Published in the Journal
As society grapples with the urgent need to address climate change, the implications of rising carbon dioxide (CO2) levels go beyond just environmental concerns. New research suggests that high atmospheric CO2 concentrations can lead to significant changes at the cellular level in humans. The interaction of CO2 with biological molecules is beginning to reveal a
Recent advancements in biochemistry have unveiled critical insights into the enzymatic processes that facilitate cancer growth, particularly involving serine hydroxymethyltransferase (SHMT). A research team from the Department of Energy’s Oak Ridge National Laboratory (ORNL) employed neutron experiments to delve into the vital functions of this enzyme, a pivotal component in the metabolic pathways regulating cell
The pursuit of cleaner energy sources is at the forefront of addressing global climate change and fossil fuel dependency.
