ChemPur delivers more than 3,500 metals and compounds, inorganic specialty chemicals, nano powder, as well as more than 100,000 organic intermediates. Our range of products include precious metal compounds and rare earth compounds, precious metal semi-finished products, sputtering targets from meta more
Plansee is the expert in the field of molybdenum, tungsten, tantalum, niobium and chromium products. Refractory metals, alloys and composite materials from Plansee come into use in electronics, coating technology or high-temperature furnaces - wherever traditional materials are stretched beyond thei more
The Lab Solutions business unit of Merck Millipore supplies products for research, analytical and clinical laboratories in a wide variety of industries. We are one of the leading suppliers of laboratory chemicals, lab water equipment and consumables. For inorganic chemistry, we offer reagents, refer more
Water electrolysis could provide high-quality hydrogen gas that can be used in fuel cells directly. However, since noble metals, such as platinum and iridium, are currently needed to initiate such a reaction, the cost is very high. "Obviously, catalysts that are low-cost with high-activity are neede more
Since their experimental discovery, magnetic skyrmions - tiny magnetic knots - have moved into the focus of research. Scientists from Hamburg and Kiel have now been able to show that individual magnetic skyrmions with a diameter of only a few nanometres can be stabilised in magnetic metal films even more
Additive manufacturing's promise to revolutionize industry is constrained by a widespread problem: tiny gas pockets in the final product, which can lead to cracks and other failures. New research led by teams from Carnegie Mellon University and the U.S. Department of Energy's (DOE) Argonne National more
Geologists analyze soil samples, the oil industry studies crude oil, and the steel industry wants to know the composition of slag. These are completely different fields, but all begin the analysis process with a high-temperature fusion treatment of t more
Simple, fast, accurate and precise oil and fuel analysis using ICP-OES with radial plasma observation more
The second of a series of infographics on the groups of the periodic table, here some general properties of the group 2 elements are examined. As stated previously, these are primarily aimed at secondary school students, hence the relative simplicity and generality of the information presented. more
I wanted to display all the key points about each group of elements, in a way that was both clear and engaging for the pupils – as a consequence, the information presented is relatively basic, so that it’s accessible for as many of the year groups as possible. I also tried to include some informatio more
The metal reactivity series is a commonly taught concept in chemistry, placing the metals, as its name suggests, in order of reactivity from most reactive to least reactive. It’s also a useful tool in predicting the products of simple displacement reactions involving two different metals, as well as more
We report electromagnetic interference shielding of metals decorated MWCNT/rGO in polyvinylidene fluoride (PVDF) flexible films. X-ray diffraction patterns show the presence of metallic nanoparticles firmly bound with carbon fillers of the composite. The morphological studies proved the homogeneous more
The rare earth elements (REEs) play critical roles in modern consumer electronics and clean technologies, but unpredictable supply and environmentally unsustainable extraction practices have spurred efforts to develop green methods of recovering the metals from waste streams. In this regard, we have more
An X-ray diffraction study of [6]cycloparaphenylene (1), crystallized under solvent-free conditions, revealed a unique solid state structure with tight packing of individual molecules that minimizes empty internal space. The controlled chemical reduction of this highly strained nanohoop with Group 1 more
