The success factors include technological competence, special industry solutions and direct presence in important markets. Dürr offers all key technical procedures of a more
On a high level of plant availability, the substances in the water are safely and reliably destroyed by means of hydrogen peroxide and UV radiation. more
Sievers InnovOx Total Organic Carbon (TOC) Analyzers are designed to measure organic carbon across a broad range of water samples. more
Nanocatalysts made of gold nanoparticles dispersed on metal oxides are very promising for the industrial, selective oxidation of compounds, including alcohols, into valuable chemicals. They show high catalytic activity, particularly in aqueous solution. A team of researchers from Ruhr-Universität Bo more
Chemical oxidation, the selective removal of electrons from a substrate, represents one of the most important transformations in chemistry. However, most common oxidants often show disadvantages such as undesired side reactions. The chemist Marcel Schorpp and colleagues from the group of Prof. Dr. I more
Scientists at Tokyo Institute of Technology have shown that copper oxide particles on the sub-nanoscale are more powerful catalysts than those on the nanoscale. These subnanoparticles can also catalyze the oxidation reactions of aromatic hydrocarbons far more effectively than catalysts currently use more
From industrial process water and wastewater to concentrated brine and acid, Sievers InnovOx Total Organic Carbon (TOC) Analyzers are designed to measure organic carbon across a broad range of water samples. Offering a dynamic operating range of 50 ppb to 50,000 ppm, this analyzer ensures superior T more
Removing of Highly Active Impurities – Such as Active Pharmaceuticals – from Industrial Wastewater more
Production processes in the chemical and pharmaceutical industries give rise to gaseous and liquid residues that are preferably disposed of in decentralized incinerators. Most of these residues are highly caloric gases and solutions containing high c more
In all oxygen consuming cells, metabolism and oxidative stress generate several intermediates and byproducts that are collectively known as reactive oxygen species (ROS). ROS are necessary intermediates in the human body, but they are also involved i more
The efficiency of diluted acids for digestion of organic samples was tested as an alternative to common digestion procedures more
The oxidation state of elements are largely dependend on their position in the periodic table. Main group elements have usually less numbers of oxidations states. Transition metal often have a wider range of possible oxidaions states. more
Here’s the second part of the Chemical Reactions posters, this time featuring condensation, hydrolysis, displacement, oxidation, and reduction reactions. Click the image above to enlarge and read the text. more
Today’s post is a quick one with a look at alcohol oxidation reactions. This graphic tries to provide a basic summary of the reagents used, equipment required, and ways of identifying the products formed. A prominence is given to sodium and potassium dichromate as oxidising agents, despite the fact more
A nickel-titanium oxide (NiO/TiO2) coating was in situ grown on a nickel-titanium alloy (NiTi) fiber substrate by anodic oxidation. After annealing, a uniform and dense Ni-free coating of rutile phase TiO2 submicrorods (TiO2SRs) was formed. In particular, TiO2SRs were embedded into the NiTi fiber su more
For the first time, black phosphorus quantum dots (BP QDs) were found to show chemiluminescence (CL) properties in the presence of hydrogen peroxide (H2O2) and hypochlorite (ClO−). Excited phosphorus oxides (HPO) resulting from the oxidation of BP QDs account for CL emission. Taking triacetone tripe more
In light of the high affinity of Cu2+ for Alzheimer's Aβ1–42 and its ability to subsequently catalyze the formation of radicals, we examine the effects of Cu2+ binding, Aβ oxidation, and an acidic environment on the conformational dynamics of the smallest Aβ1–42 oligomer, the Aβ1–42 dimer. Transitio more
Andrussov oxidation The Andrussov Oxidation is an organic reaction describing the oxidation of methane in the presence of oxygen, ammonia, and a platinum catalyst to produce hydrogen cyanide. :CH4 + NH3 + 1.5O2 → HCN + 3H2O References more
