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.....»»
Twitter Could Be Working On Facebook-Style Reactions
Twitter could be adding some new emojis to augment its formerly star-shaped, currently heart-shaped Like button, according to app researcher Jane Manchun Wong. The Verge reports: The assets Wong found -- which have been reliable predictions of future.....»»
Metamaterials offer multifunctional materials for engineering
In recent years, the popularity of metamaterials has increased significantly. These materials are not found in nature or made using chemical reactions, but are designed geometrically in the physics lab. Metamaterials can be given special, often count.....»»
Can"t stand chewing or breathing sounds? Scientists have discovered why
People who have extreme reactions to sounds such as chewing or loud breathing may have a "supersensitised" brain connection, according to a study......»»
The birth of a subnanometer-sized soccer ball
Ever since the existence of molecules was proven and molecular reactions were predicted, humans have wanted to visually observe how such events proceed. Such observations of single-molecule reactions are highly important for the fundamental understan.....»»
What causes tropospheric ozone pollution over northern Tibetan Plateau?
Atmospheric ozone, which can regulate the amount of incoming ultraviolet radiation on the Earth's surface, is important for the atmospheric environment and ecosystems. Tropospheric ozone, primarily originating from photochemical reactions, is the thi.....»»

A new book goes micro to show the wonderful world of close-up chemical reactions......»»
Nuclear Reactions Are Smoldering Again At Chernobyl
An anonymous reader quotes a report from Science Magazine: Thirty-five years after the Chernobyl Nuclear Power Plant in Ukraine exploded in the world's worst nuclear accident, fission reactions are smoldering again in uranium fuel masses buried deep.....»»
Improving quality of life for cats with renal disorders: Drugs with minimal reactions
Many cats develop chronic renal disorders as they age. As chronic renal disorders progress, the secretion of erythropoietin (EPO), a hematopoietic factor produced in the kidneys, is decreased, which causes renal anemia. Veterinary medicine, until now.....»»
No, the new iMac isn"t ugly. The design and colors are a breath of fresh air
When Apple unveiled its colorful new iMac line at a virtual product launch earlier this week, reactions were divided: They're beautiful. They're ugly. What is with that 'chin'?.....»»
Engineering single-molecule fluorescence with asymmetric nano-antennas
NIR fluorescence has shown great potential in bioscience, but low quantum-yield has largely impeded research on most NIR fluorophores. Here, scientists in China use asymmetric plasmonic nano-antennas to drastically enhance an NIR dye's single-molecul.....»»
Scientists uncover structure of light-driven enzyme with potential biofuel applications
Although many organisms capture and respond to sunlight, enzymes—proteins that catalyze biochemical reactions—are rarely driven by light. Scientists have identified only three types of natural photoenzymes so far. The newest one, discovered in 20.....»»
Asymmetric synthesis of aziridine with a new catalyst can help develop novel medicines
Unless you've studied chemistry in college, it's unlikely you've come across the name aziridine. An organic compound with the molecular formula, C2H4NH, aziridines are well-known among medicinal chemists, who make use of the compound to prepare pharm.....»»
Sustainable chemical synthesis with platinum
Researchers used platinum and aluminum compounds to create a catalyst which enables certain chemical reactions to occur more efficiently than ever before. The catalyst could significantly reduce energy usage in various industrial and pharmaceutical p.....»»
