Iridium-catalyzed Z-retentive asymmetric allylic substitution reactions
In synthetic organic chemistry, Z-olefins are a challenging synthetic target to produce in the lab due to their relative thermodynamic instability. The Z-olefins form an unsaturated compound with a CnH2n formula that can be readily isomerized. Analog.....»»
Research offers new understanding of complex catalysis, advances catalyst design
Many of the catalytic reactions that drive our modern world happen in an atomic black box. Scientists know all the components that go into a reaction, but not how they interact at an atomic level......»»
Hyperpolic shear polaritons in low-symmetry crystals
Scientists from the Fritz Haber Institute of the Max Planck Society, Vanderbilt University, City University of New York, University of Nebraska, and University of Iowa have just published new results on asymmetric light-matter waves in the journal Na.....»»
Study reveals how sulfate-reducing bacteria respond to biocides
Almost all materials immersed in seawater are suffering from microbiologically influenced corrosion (MIC). MIC catalyzed by sulfate reducing bacteria (SRB) can cause pipeline network damage. The non-oxidizing biocide tetrakis hydroxymethyl phosphoniu.....»»
Alarm Raised After Microsoft Wins Data-Encoding Patent
Microsoft last month received a US patent covering modifications to a data-encoding technique called rANS, one of several variants in the Asymmetric Numeral System (ANS) family that support data compression schemes used by leading technology companie.....»»
Rare Form of Sulfur Offers a Key To Triple-Capacity EV Batteries
Engineers at Drexel University have made a breakthrough they say takes [lithium-sulfur batteries] closer to commercial use, by leveraging a rare chemical phase of sulfur to prevent damaging chemical reactions. New Atlas reports: [T]here is one proble.....»»
Steering conversion of carbon dioxide and ethane to desired products
Converting carbon dioxide (CO2) and ethane—an underutilized component of natural gas—into things we need would be a great way to put a potent greenhouse gas and an unused reservoir of hydrocarbons to work. But driving such reactions specifically.....»»
COVID Vaccines Can Be Safe for People with Prior Allergic Reactions
My colleagues and I use a protocol to inoculate safely, and the CDC needs to revise its recommendations -- Read more on ScientificAmerican.com.....»»

Avoiding chains of magnetic islands may lead to fusion paradise
To create the conditions needed for fusion reactions, tokamak reactors contain a plasma in magnetic fields. These magnetic fields can contain tubular areas called magnetic islands. Plasma particles move extra quickly across these islands. This preven.....»»
For sustainable sulfur-tolerant catalysts, alloy precious metals with phosphorus
Catalysts play crucial roles in chemical processes. However, many conventional catalysts have suffered from deactivation caused by sulfur-containing molecules which are strongly absorbed onto catalyst surfaces and suppress catalytic reactions. Osaka.....»»
Common household cleaner can boost effort to harvest fusion energy on Earth
Scientists have found that adding a common household cleaning agent—the mineral boron contained in such cleaners as borax—can vastly improve the ability of some fusion energy devices to contain the heat required to produce fusion reactions on Ear.....»»
