Stereoselective alkene synthesis with non-precious nickel catalysis
NUS chemists have developed a new way to access prized tri- and tetrasubstituted alkenes through a nickel-catalyzed tandem process involving a Heck reaction followed by carbon-carbon double bond (C=C) migration......»»
How chemical reactions compute
A single molecule contains a wealth of information. It includes not only the number of each kind of constituent atom, but also how they're arranged and how they attach to each other. And during chemical reactions, that information determines the outc.....»»
New tool enables mapping of protein interaction networks at scale
Proteins—long chains of amino acids—each play a unique role in keeping our cells and bodies functioning, from carrying out chemical reactions, to delivering messages, and protecting us from potentially harmful foreign invaders. More recent resear.....»»
Harmful algal blooms jeopardize health of reptiles, songbirds
Toxic algal blooms in the Great Lakes region cause mixed reactions in wildlife, from higher stress levels to weaker immune systems......»»
Finding the cause of a fatal problem in rocket engine combustors
Rocket engines contain confined combustion systems, which are essentially combustion chambers. In these chambers, nonlinear interactions among turbulent fuel and oxidizer flows, sound waves, and heat produced from chemical reactions cause an unstable.....»»
Iridium-catalyzed hydrogen addition, giving plant- and insect-based natural substances
The cost-effectiveness of drug synthesis depends on a number of factors, including the amount of waste produced. A team of researchers have now discovered a catalyst that achieves exceptionally high-precision addition of hydrogen to carbon-carbon bon.....»»
Facebook Pauses Sales of the Oculus Quest 2 Due To Face Irritation Concerns
