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.

Wiley is pleased to announce the publication of a practical how-to guide to apply and re-apply to the National Science Foundation (NSF), written by authors with successful grant histories and NSF "insider" knowledge.
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.

Inverse Fingerprints on Paper: Visualization of Latent Fingermarks by Nanotechnology: Reversed Development on Paper: A Possible Remedy to the Variation in Sweat Composition
Paper is one of the surfaces most commonly tested for fingerprints in forensics. Unfortunately, it is particularly difficult to make fingerprints on paper visible. In the journal Angewandte Chemie, Israeli scientists have now introduced a new method developed specifically for use on paper. It produces a “negative” of the fingerprint and is, in contrast to conventional methods, independent of the composition of the sweat residue left behind.
