Analytical techniques such as Titration, Chromatography, and Spectroscopy are only as reliable as the quality of solvents and inorganics that you use more
See how premium quality, unique packaging, and new 2D data matrix labels make EMSURE® inorganics and solvents the smartest choice for precise analysis. more
The tiny rings that chemists at the Center for Nanointegration (CENIDE) at the University of Duisburg-Essen (UDE) create in the laboratory are as small as a bacterium. Self-organized, individual polymer chains form the flexible structures that can even squeeze themselves through cell membranes. This more
They look like interlocking egg cups, but a hen's egg is 100,000 times as thick as one of the miniature cups: Scientists at the Center for Nanointegration (CENIDE) at the University of Duisburg-Essen (UDE) have made polymers to form themselves into tiny cups on their own. They could, for example, be more
How can the share of bio-based raw materials used in the European chemical industry be increased to 25 % by 2030? As conclusion of its two-year work, the EU project RoadToBio has published a roadmap that outlines how this goal could be achieved. Based on the analysis of nine product groups, the road more
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
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
In today's competitive skin care market, consumers look for a range of benefits, superior aesthetics and cost effectiveness. more
By amending methodology to utilize eVol® for sample preparation processes for GC-C-IRMS C isotope ratio analysis, the ISORA department has: improved sample preparation conditions and the GC-C-IRMS analysis results by removing the risk of ghost peaks, more
Although the ancient Egyptians already used inks 5000 years ago, inks and their properties have been continuously improved and refined over thousands of years. more
If you’ve ever needed a tooth out, or had surgery of any kind, chances are you’ll have experienced use of an inhalational anaesthetic. All of the compounds shown above can induce general anaesthesia, and a range have been utilised since the initial discovery of nitrous oxide in the mid-1800s. Often, more
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
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
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
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
