Researchers at the universities in Linköping and Shenzhen have shown how an inorganic perovskite can be made into a cheap and efficient photodetector that transfers both text and music. "It's a promising material for future rapid optical communication", says Feng Gao, researcher at Linköping Univers more
The discovery of lead in Flint, Michigan's drinking water drew renewed attention to the health risks posed by the metal. Now researchers at the University of Houston have created an inexpensive system using a smartphone and a lens made with an inkjet printer that can detect lead in tap water at leve more
Scientists can spend a long time in heated debates over tiny details – for example, how and whether atoms in a crystal move when heated, thereby altering the symmetry. Using computer simulations for the mineral lead telluride on the CSCS supercomputer “Piz Daint”, ETH researchers have resolved a lon more
A new molecular gel recipe developed at the University of Michigan by Anne McNeil, Arthur F Thurnau Professor of Macromolecular Science, and is at the core of a prototype for a more accurate lead paint test.The new test is more clear and accurate than its counterparts. It consists of a vial that ... more
Virginia Tech researchers helped prove that lead levels were dangerously high in Flint’s tap water, even when government officials denied the problem. We visited the researchers to see how they're using standard analytical chemistry to try and make water safer. more
The aim of this work was to demonstrate the performance of Whatman Grade 40 and Grade 41 quantitative ashless filter paper in specific mining industry applications. Whatman Grade 40 and Grade 41 filter paper was evaluated in three metal content tests more
Corrosion in refinery operations has been, and still is, the subject of many studies, papers, courses and web forums. Although a lot of what has been written shows that significant progress in understanding corrosion has been made, it also makes it more
This latest infographic focuses on the Group 4 (Group 14 in IUPAC nomenclature) elements. One extra fact to add for the curious: although tin has the greatest number of stable isotopes, Xenon trumps it comprehensively if unstable isotopes are also included in the count, with well over 30 possible is more
Kicking off an occasional new series of graphics with today’s post, which’ll be looking at common chemical reactions encountered in schools. Today kicks off with one of my favourite reactions, the ‘Golden Rain’ demonstration, which involves the synthesis and recrystallisation of lead (II) iodide, an more
18th May marks the date of birth of Thomas Midgley, who made significant contributions to something many of us make use of on a regular basis: petrol. Midgley was the research assistant to Charles Kettering, and the duo were responsible for the addition of the compound tetraethyl lead to petrol, an more
The interactions between metals and two-dimensional materials, in particular, the adsorption energies, strongly determine the performances of rechargeable batteries. Previously, it has been demonstrated that heterostructures of two dimensional (2D) materials can lead to enhanced metal adsorptions, w more
Surface-catalyzed reactions provide a versatile route to synthesizing new 2D materials. Here, we show that the statistical nature of an activated reaction can lead to a diversity of intermolecular bonding motifs through partially-reacted molecules. With increasing annealing, we observe different per more
The variation of center atom in cation from N to P-atom lead to improved physio-chemical properties of protic ionic liquids (PILs) which are suitable for electrolyte applications. We present atomistic simulations study to compare the effect of alkyl or aryl group on trioctylammonium triflate ([HN(Oc more
BMI View: Peru's agricultural exports grew by 16.6% year-on-year (y-o-y) in value terms over the first quarter of 2012 to reach US$915.mn, according to Ministry of Agriculture data. Higher export prices for a number of key products, including coffee, mangoes, avocado, asparagus and evaporated milk, more
BMI’s China Petrochemicals Report Q312 examines the long-term growth trends that are in play across the local industry, but warns of short-term concerns about over-capacity and the impact on prices and trade. This report analyses the way in which the slowdown in Chinese construction activity is af more
As the main component of turpentine, alpha-pinene (β-pinene) and beta-pinene (β-pinene) are also important forest chemicals in China. Since a large amount of pinene is exported annually in recent years, the global economy situation is very important for pinene industry. After global financial cr more
