The Table that defines chemistry turns 150
The Table that defines chemistry turns 150
The ‘Periodic Table of Elements’, or simply, ‘The Table’ for many, was written by Dmitri Ivanovich Mendeleev on 17th February 1869. Looking back, the Table opens a window to the world of inanimate matter. Mendeleev’s profound impact on chemistry is comparable to those of his contemporaries, Gregor Mendel and Charles Darwin in genetics and evolution, respectively. Therefore, the United Nations General Assembly and UNESCO have decided to celebrate 2019 as the “International Year of the Periodic Table of Chemical Elements (IYPT2019)”.

Millions of tons of plastic waste could be turned into clean fuels, other products
Millions of tons of plastic waste could be turned into clean fuels, other products
A new chemical conversion process could transform the world's polyolefin waste, a form of plastic, into useful products, such as clean fuels and other items. The conversion process incorporates selective extraction and hydrothermal liquefaction. Once the plastic is converted into naphtha, it can be used as a feedstock for other chemicals or further separated into specialty solvents or other products.

Scientists develop promising new type of polymers
Organic polymers can nowadays be found in solar cells, sensors, LEDs and in many other technical applications. One specific type of polymers - known as S-PPVs - were previously regarded as promising in theory but were almost impossible to produce from a technical perspective. After many years of work, a team has now managed to identify a new chemical synthesis process for the production of S-PPVs.

Engineered sand zaps storm water pollutants
Engineers have created a new way to remove contaminants from storm water, potentially addressing the needs of water-stressed communities that are searching for ways to tap the abundant and yet underused source of fresh drinking water. The mineral-coated sand reacts with and destroys organic pollutants, providing a way to help purify storm water percolating into underground aquifers, creating a safe and local reservoir of drinking water for parched communities.

Chemists make breakthrough on road to creating a rechargeable lithium-oxygen battery
Chemists have successfully resolved two of the most challenging issues surrounding lithium-oxygen batteries, and in the process created a working battery with near 100 per cent coulombic efficiency. The new work demonstrates that four-electron conversion for lithium-oxygen electrochemistry is highly reversible. The team is the first to achieve four-electron conversion, which doubles the electron storage of lithium-oxygen, also known as lithium-air, batteries.

The Chemistry of Sparklers Explained in Slow-motion Video
It's powdered metals catching fire, and what you see fly off into lovely sparkles are actually tiny ignited fragments of metal. They're also super hot — from 1800 to 2900 degrees Fahrenheit (1000 to 1600 degrees Celsius), but burn up quickly due to their microscopic size.
The different colors you'll see in a sparkler are produced by different colorants, which are metals that produce different colors of light when they burn: strontium burns red, for instance, and copper blue

'Electrogeochemistry' captures carbon, produces fuel, offsets ocean acidification
Limiting global warming to 2 degrees Celsius will require not only reducing emissions of carbon dioxide, but also active removal of carbon dioxide from the atmosphere. This has prompted heightened interest in 'negative emissions technologies.' A new study evaluates the potential for recently described methods that capture carbon dioxide from the atmosphere through an 'electrogeochemical' process that also generates hydrogen gas for use as fuel and creates by-products that can help counteract ocean acidification

The tiny robots, which are a millionth of a millimetre in size, can be programmed to move and build molecular cargo, using a tiny robotic arm.
Each individual robot is capable of manipulating a single molecule and is made up of just 150 carbon, hydrogen, oxygen and nitrogen atoms. To put that size into context, a billion billion of these robots piled on top of each other would still only be the same size as a single grain of salt.
