Inspired by Audio Cassettes: Economical nanostructured iron–cobalt catalysts for the Fischer–Tropsch synthesis
Audio cassettes make the production process for fuels less expensive: To produce nanoparticles made of inexpensive iron oxide cores with a very thin cobalt shell, an international team of researchers modified a method developed for the production of magnetic audio tapes. As the researchers report in the journal Angewandte Chemie, their particles are easily accessible on a large scale, and are excellent Fischer–Tropsch catalysts for the production of good diesel fractions.
Diamond Wires: Carbon nanowires obtained by tempering diamantane dicarboxylic acid inside carbon nanotubes
Carbon-based nanomaterials have unique properties that make them useful for many technical applications, including lightweight construction, electronics, energy generation, environmental technology, and medicine. In the journal Angewandte Chemie, an international team of researchers has now introduced a new process for the production of especially fine carbon nanowires from carbon in the diamond configuration. In this process, molecules with a diamond-like structure are linked together inside a carbon nanotube.
Airy but Thirsty: Ultralight, flexible, fire-resistant carbon nanotube aerogels from bacterial cellulose
They can absorb vast amounts of oil or organic compounds, yet they are nearly as light as air: highly porous solids made of a three-dimensional network of carbon nanotubes. In the journal Angewandte Chemie, Chinese scientists have now introduced a simple technique for the production of these ultralight, flexible, fire-resistant aerogels. Their method begins with bacterial cellulose as an inexpensive starting material. Their fibrous lightweights can "suck" organic contaminants from polluted water and could possibly be used as pressure sensors.
When gluing things together, both surfaces usually need to be dry. Gluing wet surfaces or surfaces under water is a challenge. In the journal Angewandte Chemie, Korean scientists have now introduced a completely new concept. They were able to achieve reversible underwater adhesion by using supramolecular "velcro".

Squeezing Out CO2. Post-combustion capture: metal-organic framework releases stored carbon dioxide in sunlight
In order to reduce the carbon dioxide output from coal power plants, CO2 could be removed from their exhaust (post-combustion capture) and stored or, if possible, used as a carbon source for chemical syntheses. Previous approaches to this have suffered from the fact that they require too much energy. In the journal Angewandte Chemie, Australian scientists have now introduced a new metal–organic framework compound that absorbs CO2 and then releases it upon exposure to sunlight.
Uncovering Pathogens Outside the Lab. DNAzymes and gold nanoparticles: a colorimetric assay for diagnostics in the field
Infectious diseases such as malaria and syphilis can be diagnosed rapidly and reliably in the field by using a simple test developed by Canadian scientists. The test is based on the use of DNAzymes and gold nanoparticles. As the researchers report in the journal Angewandte Chemie, their test allows for the sensitive detection of bacteria, viruses, and parasites.
Wiley has launched Labtiva’s ReadCube Web Reader on Wiley Online Library, making it easier for researchers to discover, access and interact with scientific literature.
Irradiation with light is an established method for initiating polymerization or crosslinking (curing) in the production of plastics. American researchers are now using light to retroactively increase the size of the pores within a polymer network. As reported in the journal Angewandte Chemie, this new approach allows for the production of polymer gels with tailored mechanical properties.
Published by Wiley, this new 10-volume set captures every aspect of the interdisciplinary nature of magnetic resonance and provides the most complete and up-to-date source in the field.
It All Depends on the Length. Chemical functionalization of ‘toxic’ long carbon nanotubes reduces their effective length and alleviates asbestos-like pathogenicity
Carbon nanotubes resemble asbestos fibers in their form. Unfortunately, long, pure nanotubes also seem to have asbestos-like pathogenicity. In the journal Angewandte Chemie, a European research team has now reported that chemical modifications, for example with tri(ethylene glycol), can alleviate this problem if the modification makes their surface more water-friendly and reduces the effective length of the tubes.
Clogged Pores for Increased Effectiveness. Whey protein stabilizes nanotransporter and controls pH-dependent drug release
How can pharmaceuticals be safely carried through the acidic environment of the stomach and into the intestines? A team of Canadian and Australian researchers has developed a novel nanotransporter that consists of porous particles of silicon dioxide stabilized with a whey protein. In acidic environments the protein forms a gel that closes off the pores; at higher pH values, the pores are opened.

The journal Angewandte Chemie is celebrating its 125th anniversary as a world leader - with Nobel Laureates and other luminaries
On the occasion of its 125th anniversary, the journal Angewandte Chemie is treating its readers to a special issue, which contains no less than 16 contributions from chemistry Nobel Laureates, and also a symposium that will take place in Berlin in March and will feature three Nobel Laureates. In its 125-year history, the journal has developed from a magazine for the chemical industry in German-speaking countries (that's where the name of the journal comes from: Angewandte Chemie means "applied chemistry") to a modern global medium for fundamental chemical research. Both the English and German editions are available electronically, a form that has long since overtaken the printed issues. The journal has always been owned by scientific societies, and since 1947 it has been in the hands of the Gesellschaft Deutscher Chemiker (GDCh; German Chemical Society), in close cooperation with its scientific publisher Wiley-VCH.
