Jean-Francois Charles, assistant professor in composition and digital arts, wanted to expand on a piece of music he previously composed to incorporate more chemical elements. Johna Leddy, associated professor of chemistry, suggested he reach out to Benjamin Revis. As the UI's professional scientific ...

Abstract: Energy dispersive X‐ray fluorescence (EDXRF) technique, as a qualitative and quantitative analysis, was used for inorganic chemical elements determination (K, S, Cl, Al, Si, Ca, Ti, Mn, Fe, Pb, Zn, Rb, and Bi) in eyeshadows for safe human use. International Nomenclature of Cosmetic Ingredients ...

Hello? Is there anyone out there? DAVID NIELD. 6 APR 2018. One of the chemical elements essential to life is phosphorus, but the latest research suggests there may be less of it in the wider Universe than we thought. That could be bad news for those hoping to find alien life out there in space. Scientists think that life-giving ...

Phosphorus, while probably not part of your daily lexicon, is one of just six chemical elements on which Earthly life depends. The element, represented by the chemical code 'P', is also a key component of adenosine triphosphate (ATP), the compound which cells use to store and transfer energy. Not one of your more ...

... Northridge (CSUN) chemistry professor Maosheng Miao, and including University at Buffalo chemistry professor Eva Zurek, has provided a theoretical explanation of how helium may be capable of forming stable compounds—the myriad combinations of chemical elements that create all kinds of materials ...

"The chemical elements join together to form a compound, sort of like a family," he explained. "But, like in any family, not everyone gets along -- in this case because you either have too many negative or positive ions. "Now, we're going to apply pressure to make this compound work, which is like putting this ...

A new study from a team at the National Institute of Environmental Health Sciences (NIEHS) is rekindling a debate over the safety of essential oils. The research suggests lavender and tea tree oils contain potential hormone disrupting chemicals and could be responsible for a condition called prepubertal gynecomastia, ...

Most cell phones contain precious metals, chemical elements and minerals, including copper, gold, lead, zinc, beryllium, tantalum, coltan, as well as plastics that can be recycled to save energy and resources that would otherwise be required to mine or manufacture. There are several e-waste facilities in ...

There she met and married her husband which started a partnership that discovered two new chemical elements: polonium (named in honor of her native country) in the summer of 1898, and radium a few months later. She isolated pure metallic radium and used this discovery to obtain her doctorate of ...

There is a flood of new electronic and electrical devices reintroducing toxins very similar to those in tobacco smoke, diesel fumes, asbestos and other killers. Some of these devices will sell in up to billions yearly but there has been no tracking of the big picture of imminent toxic threat from the balance of ...

The project is part of a multinational collaborative effort called GEOTRACES that aims to better understand global ocean circulation and marine cycles by examining the distribution of dissolved and particulate chemical elements suspended in the water column. 'If we lose (the ice shelves), the speed of the ...

The car covers are required for all vehicles that are revealed to climate and other chemical elements. Substances such as bird droppings and acid rains, rust the external finish of the car making it wear off fast. The price of repairing damage finish does cost you up for a depending on various factors like the extent of the ...

compound (often used as a synonym for chemical) A compound is a substance formed when two or more chemical elements unite (bond) in fixed proportions. For example, water is a compound made of two hydrogen atoms bonded to one oxygen atom. Its chemical symbol is H2O. CRISPR An abbreviation ...

One could be forgiven for thinking that the periodic table of chemical elements is a dusty relic with nothing new to say. Today the periodic table is more commonly found in textbooks than newspapers. Yet it was only in 2016 that the latest additions to the table were officially named. Clearly, the periodic table ...

Ramsay was awarded a Nobel Prize in 1904 for discovering five elements. Henry Moseley, an experimental physicist, contributed to the development of the modern periodic table when he discovered in 1913 that each element has a specific number of protons. As a result, four new chemical elements were ...

Flerovium-capturing sulfur cages could finally reveal where in the periodic table the superheavy element belongs. Periodic table showing position of flerovium. Source: © Antoine2K / Sutterstock. 'Flerovium might not belong [where it currently sits in the periodic table], so in other words Mendeleev's table is ...

It is made from chemical elements which are harmless on their own but lethal when combined. Theresa May's first scenario, that the Kremlin was directly involved, seems unlikely. Skripal was in the UK as part of an official spy-swap deal with Russia. The only suggestion of suspicious activities on Skripal's ...

Helium has long confounded scientists regarding what role it plays in the formation of stable, solid compounds – the myriad combinations of chemical elements that create all kinds of materials. As a noble gas — so labeled because helium was believed “too aloof” to react with the other elements on what is ...

Chemical elements on the periodic table also have family resemblances that could provide predictive insight into the way elements interact, leading scientists to not-yet-imagined applications. In the case of one element, protactinium, chemical similarities produced by the configuration of its outermost ...

A new international poll said Albert Einstein's theory of relativity was inspired during his sleep. In that same poll, Einstein's theory was considered the greatest idea ever. Other notable ideas conceived during sleep include: the periodic table of chemical elements, the invention of the sewing machine, the model of the atom, ...
