• Polypropylene recycling from carpet waste
  

  A significant part of carpet waste consists of petroleum-based polypropylene. As a non-recyclable product, disposing of it has previously meant incineration or landfill. However, a new solvent is now making it possible to recover virgin-standard polypropylene from carpet waste — with no perceptible more

Cyrene™ Bio-Renewable Dipolar Aprotic Solvent

Due to their health hazards, NMP and DMF are now included in the REACH restriction list. If you had regularly used these solvents, you’ll be glad to know we offer a perfect alternative: Cyrene™. Our “green” dipolar aprotic bicyclic chiral solvent is harmless for users, safer for the environment, and more

Accelerated Solvent Extraction (ASE) – Maximize results and reduce errors in food analysis!

Food safety is defined as “the absence of adverse health effects due to food contamination”. Contaminants are substances that have not been intentionally added to food. These substances may be present in food as a result of the various stages of its production, packaging, transport or holding. They more

Acetone Dissolves Styrofoam Into Goo

Have you ever seen a foam cup appear to melt away in acetone? Foam cups, bowls and containers are made of a lightweight but strong material – expanded polystyrene. How then does acetone reduce this substance to a blob of goo? In this week’s video, we team up with chemistry professor Matt Harting ... more

• Sustainable hydrophobic terpene-based eutectic solvents for the extraction and separation of metals

  Sustainable hydrophobic eutectic solvents, composed of low-priced and biodegradable terpenes and fatty acids, were used for the extraction and separation of Cu(II) from other transition metals in mildly acidic solutions. Multiple parameters were evaluated for metal extraction and the hydrophobic eut more

• Continuous detection of HCl and NH3 gases with a high-performance fluorescent polymer sensor

  A novel fluorescent triazine-based covalent organic polymer (COP-1) sensor toward HCl and NH3 gases has been designed and synthesized. Both the COP-1 powders dispersed in solvents and the COP-1 film formed on surface of quartz sheets exhibit stable fluorescence and sensitive HCl/NH3 response. Immers more

• First-principles calculations of oxidation potentials of electrolytes in lithium–sulfur batteries and their variations with changes in environment

  Oxidation potentials of electrolyte molecules in Li–sulfur (Li/S) batteries and their variations in various solvent environments are investigated using first-principles calculations in order to understand oxidative decomposition reactions of electrolytes for cathode passivation. Electrolyte solvents more

• Water instead of mineral oil
  

  Optical active substances made from chiral catalysis form the basis of many drugs. Expensive precious-metal catalysts are required for the chemical production, which due to their thermal instability decompose at high temperatures and can therefore only be used once. The innovative process of DexLeChem GmbH makes it possible for the first time to use these precious-metal catalysts made from rhodium, ruthenium or iridium more than once, without modifying them. At the same time, reaction occurs in aqueous solutions instead of mineral-oil-based solvents, which increases the sustainability of the process. This is a milestone in catalysis and a real opportunity for the pharmaceutical industry. more
