2+ hour, 1+ min ago (407+ words) Elusive atomic oxygen finally seen inside water using cutting-edge laser imaging Scientists have captured the first-ever image of individual atomic oxygen dissolved in water, using an advanced laser approach that reveals previously unknown behaviors of this highly reactive species. The breakthrough provides direct visual evidence of how atomic oxygen moves and survives in aqueous environments. This is an area where measurement has long been considered nearly impossible. Atomic oxygen is known for its powerful oxidative properties and is central to applications in medicine, industrial chemistry, and fundamental research. Yet its behavior in liquids has remained poorly understood because oxygen atoms are difficult to detect without disturbing the very conditions needed to study them. Until now, researchers lacked a tool capable of directly measuring atomic oxygen concentrations in water without causing degradation or triggering unwanted chemical reactions. For years, attempts to…...

2+ hour, 14+ min ago (433+ words) A number of advanced energy technologies " including fuel cells, electrolyzers, and an emerging class of low-power electronics " use protons as the key charge carrier. Whether or not these devices will be widely adopted hinges, in part, on how efficiently they can move protons. One class of materials known as metal oxides has shown promise in conducting protons at temperatures above 400degrees Celsius. But researchers have struggled to find the best materials to increase the proton conductivity at lower temperatures and improve efficiency. Now, MIT researchers have developed a physical model to predict proton mobility across a wide range of metal oxides. In a new paper, the researchers ranked the most important features of metal oxides for facilitating proton conduction, and demonstrated for the first time how much the flexibility of the materials" oxide ions improves their ability to transfer protons. The…...

3+ hour, 7+ min ago (1181+ words) New research suggests life began in sticky gels that protected early chemistry before cells existed. (CREDIT: ChemSystemsChem) For decades, scientists have searched for clues to how life first emerged on Earth. Many theories focus on simple molecules reacting in water or on fragile protocells drifting in ancient seas. A new study from Hiroshima University offers a different view. The earliest steps toward life may have taken place inside sticky, gel-like materials attached to Earth's surfaces. This idea comes from an international team of researchers who argue that these "prebiotic gels" provided protection, structure, and stability long before true cells existed. Their work suggests that life may have learned to organize and persist inside soft, surface-bound networks rather than isolated bubbles in open water. The study, published online in the journal ChemSystemsChem, draws inspiration from modern microbial biofilms. These dense, surface-attached…...

3+ hour, 37+ min ago (175+ words) That's right " organic chemistry. All because you decided to treat dry eye disease with semifluorinated alkanes (SFAs). There are two important differences between harmful and nonharmful PFAS. Dangerous PFAS generally are in the category of perfluoroalkyl acids (PFAAs). These substances are highly water soluble (550 to 9,500 ng/mL vs. < 0.35 ng/mL for Miebo). Because of this, they have bioaccumulative properties, which is the presumed cause of their toxicity. One dramatically inhibits evaporation off the surface of the eye whereas the other is a magnificent solvent that effectively delivers a challenging active ingredient into ocular surface tissue. So, let's get right with how we talk about them. This is organic chemistry. There are no essay questions on an orgo test. Darrell E.

8+ hour, 59+ min ago (338+ words) Original story from the University of Basel (Switzerland). Nuclear pore complexes are more dynamic than previously thought, reshaping our understanding of a vital transport process in cells. Imagine the cell's nucleus as a bank vault protected by a highly sophisticated security system: the NPC. Only proteins carrying the correct "key' " specialized transport factors " are granted exclusive access. This selective control over what enters and exits the nucleus is essential for ensuring proper communication between the genome protected inside it and the cellular machinery outside. In this infographic, we dive into how AFM works, the technical features one must consider and how it can be implemented for biomechanical investigation. Now, a team led by Argovia Professor for Nanobiology Roderick Lim from the Biozentrum and the Swiss Nanoscience Institute at the University of Basel, has used high-speed atomic force microscopy (AFM) to…...
