https://lnkd.in/d3-sRfY4 Vivianite is a hydrated iron phosphate mineral (Fe3(PO4)2·8H2O), crystallized in a monoclinic system. It is the endmember of a mineral series known as the vivianite group, where minerals have the general formula A3(XO4)2·8H2O, A is a divalent metal cation and X is phosphorus P or arsenic As. Today, vivianite is attracting interest as a promising material for recovering phosphorous from wastewaters. In fact, the presence in wastewater sludges of soluble iron and phosphorus can lead to vivianite formation. As a crystal, it is a naturally occurring Van der Walls material. It can be easily characterized by means of Raman and infrared spectroscopies. Here we will consider the Raman spectroscopy, precisely that related to the hydroxyl-stretching region. We will propose the deconvolutions in q-Gaussian functions of spectra from RRUFF database, comparing the obtained results with those available from literature. Besides vivianite, we will consider also baricite and bobierrite for comparison (baricite and bobierrite are two other members of the vivianite group). About the hydroxyl-stretching region and the use of q-Gaussians, we take the chance to continue a discussion regarding the Raman spectroscopy of water, discussion that we started in March 2024.

Our latest #publication in Corrosion Science unravels the role of calcareous deposits on hydrogen uptake. The permeation of hydrogen in carbon steel under various cathodic polarization is investigated combined with in-situ electrochemical impedance spectroscopy. The results indicate calcite's dual role in hydrogen uptake: it promotes uptake for bare samples and lower cathodic currents, but inhibits it for preformed deposits and higher cathodic currents. Congrats to the lead and first author of the work Razieh Tavassolian and thanks to Kim Verbeken for the cooperation. Enjoy reading! #corrosion #hydrogen #research https://lnkd.in/e3Q_g28t

These alkali metals are so light that they can float on water, although they react vigorously when they do so. 𝑬𝒙𝒑𝒍𝒂𝒏𝒂𝒕𝒊𝒐𝒏: Lithium and sodium are alkali metals with very low densities, allowing them to float, but their reactivity makes them hazardous in water. 💬 𝑫𝒊𝒅 𝒚𝒐𝒖 𝒌𝒏𝒐𝒘? The reactivity of light metals, especially in water, makes them both fascinating and dangerous to work with! #Metallurgy #MaterialsScience #Met_Jerry #EngineeringFacts #30DayChallenge #MythBusters #Metallurgy #MaterialsScience #MythBusters #EngineeringFacts #Met_Jerry #30DayChallenge #KnowledgeIsPower #Cryogenics #Steel #Aluminum #StainlessSteel #MetallurgicalEngineering #ExtremeEnvironments #InnovationInEngineering #CryogenicMetals #BCC #FCC #CrystalStructures #EngineeringScience #SmartEngineering #IndustrialApplications #AdvancedMaterials #EngineeringExplained #MiningEngineering #everyone #fyp #anyone #ExtractiveMetallurgy #MiningTechnology #MetalsAndMining #MineralsProcessing #MiningIndustry #NaturalResources #MiningInnovation #SustainableMining #EnvironmentalEngineering #MetalExtraction #OreProcessing #MineralExploration #Geology #EnergySector #RawMaterials #IndustrialEngineering #ProductionTechnology #HeavyMachinery #ResourceManagement #EnergyInnovation #ManufacturingExcellence #AutomationInMining #GreenTechnology #SmartManufacturing #MetallurgicalProcesses #MiningSafety #LinkedIn #Networking #Learning #Success

Pacific Northwest National Laboratory's Non-Equilibrium Transport Driven Separations (NETS) Initiative is developing and evaluating next-generation separation strategies targeting critical materials.  Check here for more details https://lnkd.in/gQe2bHmy

There are 118 elements, which are represented in several rows. These are called periods. The elements that are thus placed one below the other in the periodic table, i.e. in one column, form a group. The periodic table has a total of 18 groups, eight of which are referred to as main groups. They are called: alkali metals, alkaline earth metals, boron group, carbon group, nitrogen group, chalcogens, halogens and noble gases. #abcr #GuteChemie #PeriodicTable #Elements #Chemistry #Chemicals

#Brine, a crucial raw material, is categorized into sulfate, chloride, and carbonate types: -Sulfate-Type Brine: This type of brine typically forms in salt lakes through evaporation of water supplied by surrounding rivers. -Carbonate-Type Brine: brines primarily result from magmatic CO₂ and hydrothermal activities. - Ca–Cl Brines: These brines develop through deep circulation of hydrothermal water, which interacts with rocks and sediments at high temperatures. -About...Lithium Extraction Techniques: Recent advancements in lithium extraction from brine include solvent extraction, membrane separation, and adsorption. These methods address challenges posed by high magnesium-to-lithium (Mg/Li) ratios and low lithium concentrations.

The world is going to need a lot of weird metals in the coming years, according to chemistry professor Justin Wilson at UC Santa Barbara. But he isn't talking about lithium, cobalt or even beryllium. Wilson's interested in dysprosium, which is so hidden in the periodic table that you'd be forgiven for thinking he made it up. Rare earth elements (REEs) like dysprosium have a lot of niche uses in modern electronics. So much so that the U.S. Department of Energy classifies them as "critical minerals." And while they aren't quite as rare as noble metals like platinum or gold, they are difficult to obtain from natural deposits. They also share extremely similar chemical properties, making them devilishly difficult to isolate from one another. But a team led by Wilson and postdoctoral researcher Yangyang Gao has just developed a technique to purify certain REEs at room temperature without relying on the toxic and caustic compounds currently used for the task. The results, published in the journal Angewandte Chemie International Edition, promise a safer, more effective way to process these metals from mining operations and recover them from electronic waste. https://lnkd.in/gfV4GN2z

🔬Advanced synthesis methods that fine-tune host properties and metal speciation are at the forefront of catalyst design. 💥In our most recent study, we harness mechanochemical activation to stabilize iron atoms on defective h-BN. This process simultaneously exfoliates the carrier and generates surface defects, creating optimal anchoring sites for catalytically-active iron species. Iron single atoms showcased efficient C–H activation in N2O-ODHP, enabling selective and stable propylene production. We encourage exploring mechanochemical activation for synthesizing h-BN-supported transition metal SACs. 🙌🏻A big thanks to all the co-authors for the outstanding teamwork, especially Ivan Surin and Prof. Javier Pérez-Ramírez!

Carbon Molecular Sieves belong to the group of micro porous materials characterized by the relatively high adsorption capacity and selectivity towards a wide spectrum of gases. They posses amorphous structure with well developed surface area and the pore size comparable to the effective diameter of small molecules. #WesternChemicalCorporation #import-export #internationalsales #manufacturer #CMS #turkey #UAE
