A team of researchers has invented a more efficient way to extract lithium from waste liquids leached from mining sites, oil fields and used batteries. They demonstrated that a common mineral can adsorb at least five times more lithium than can be collected using previously developed adsorbent materials. The new low-cost high-lithium-uptake process presents the […]

Global energy demand is expected to rise around 30% by 2040 according to the International Energy Agency (IEA). Hydrogen (H2) produced by the electrolysis of water, using renewable electricity, the so-called green hydrogen, has emerged as a promising energy vector to respond to this increasing energy demand with the potential to decarbonize transportation, heating, and […]

The way a particular reaction proceeds, described in terms of the steps involved, is called mechanism. The study of organic chemistry is, to a great extent, the study of reaction mechanisms and textbooks content both their description and their applications. But something has come to revolutionize the world of mechanisms: surface chemistry. On-surface synthesis is […]

Chemical contamination of water bodies on one hand, and water shortages due to overexploitation on the other, have increased the need for effective and efficient water treatment and decontamination processes. Two important aspects need to be taken into consideration to define what is an “effective and efficient” treatment. First, as current methods of removing pathogens […]

Polyfluoroalkyl substances (PFAS), a family of highly fluorinated substances, represent a danger for humans and the environment. Particularly problematic members of this family, such as perfluorooctane sulfonate (PFOS) and perfluorooctanoic acid (PFOA) appear to cause organ damage and cancer, as well as disrupting the endocrine system. Researchers have now introduced a new method for an […]

Voyager II, a NASA solar system exploration spacecraft launched in 1977, measured highly unusual magnetic fields around Uranus and Neptune. Scientists considered exotic states of so-called superionic ice as a possible explanation due to these states’ increased electrical conductivity. A new work demonstrates the existence of the previously undiscovered Ice XIX phase. It shows that […]

Just like our hands, certain organic molecules relate to each other like an image and its reflection – a phenomenon that chemists call “chirality” or “handedness”. The two mirror images of the same molecule, namely both enantiomers, often possess different biological properties. This is key, for example, for drug discovery, as many times only one […]

Light emission (fluorescence or phosphorescence) in organic molecules, in the vast majority of cases, proceeds from the lowest energy excited state irrespective of the excitation energy used. This is known as the Kasha’s rule, which states that most of the molecules are emissive from the lowest energy, same (ground state) spin multiplicity, S1 excited state […]
