A research team has discovered an electrochemical method that allows highly selective para-position single-carbon insertion into polysubstituted pyrroles. Their approach has important applications in synthetic organic chemistry, especially in the field of pharmaceuticals.
Their work is published in the Journal of the American Chemical Society on July 14.
In new research, University of California, Irvine astronomers describe how more than 200 known exoplanets are likely much larger than previously thought. It’s a finding that could change which distant worlds researchers consider potential harbors for extraterrestrial life.
Macquarie University researchers have demonstrated a technique to dramatically narrow the linewidth of a laser beam by a factor of over ten thousand – a discovery that could revolutionise quantum computing, atomic clocks and gravitational wave detection.
A new tool allows researchers to probe the metabolic processes occurring within the leaves, stems, and roots of a key citrus crop, the clementine. The big picture goal of this research is to improve the yields, flavor and nutritional value of citrus and non-citrus crops, even in the face of increasingly harsh growing conditions and growing pest challenges. To build the tool, the team – led by the University of California San Diego – focused on the clementine (Citrus clementina), which is a cross between a mandarin orange and a sweet orange. The effort is expected to expand well beyond the clementine in order to develop actionable information for increasing the productivity and quality of a wide range of citrus and non-citrus crops. The strategy is to uncover – and then make use of – new insights on how plants respond, in terms of metabolic activities in specific parts of the plant or tree, to environmental factors like temperature, drought and disease.
The interplay between quantum theory and gravity is one of the most challenging problems in physics today. Using new groundbreaking approach, researchers hope that quantum networks will help them test this interplay for the first time in actual experiments.
In the fall of 2024, Hurricane Helene made landfall in the southeastern U.S., later downgrading to a tropical storm causing strong winds, flooding and major destruction throughout Appalachia. Now, researchers and public health officials in ACS’ Environmental Science & Technology Letters provide a debrief about how their mapping of key locations, including private wells, septic systems and service facilities, helped distribute disaster relief in North Carolina — a part of Appalachia hit particularly hard by the hurricane.
