Glowing Fingerprints: Researchers make latent fingerprints visible with help from electrochemiluminescence
Fingerprints are not just important in forensics and the identification of people; they can also be used for security clearance, access control, and the authentication of documents. In the journal Angewandte Chemie, Chinese researchers have now introduced a new fast method to make fingerprints visible at high resolution.
CO2 as a Carbon Source? Homogeneous catalysis: ruthenium phosphine complex hydrogenates carbon dioxide to make methanol
Fossil-based resources are declining and their use releases the greenhouse gas CO2. Both of these problems could be significantly mitigated if we could use CO2 as a carbon source for the production of fuels and chemical feedstocks. Various different approaches are currently being explored for the catalytic conversion of CO2 to methanol (CH3OH). In the journal Angewandte Chemie, German researchers have now introduced a new possibility to conduct this stepwise reaction of CO2 in solution with help of a homogeneous catalyst.
Gram staining of bacteria is a routine diagnostic method of long standing that can be used for initial diagnoses and to simplify the choice of antibiotics. It is a simple way to classify bacteria into two classes—Gram-positive and Gram-negative—under a microscope. In the journal Angewandte Chemie, American researchers have now introduced an improvement to this method: magnetic Gram staining. This allows for the class-specific, automated, magnetic detection and separation of bacteria.
John Wiley & Sons, Inc., today announced a continued increase in the proportion of its journal titles indexed in the Thomson ISI® 2011 Journal Citation Reports (JCR). A total of 1,156 Wiley titles (approximately 76%) were indexed, representing an increase of 5% from the 2010 JCR, and including 43 titles which have been indexed for the first time.
Secret of “Fetid Fluorite” Aired: Elemental fluorine F2 detected for the first time in a natural mineral
Why does “fetid fluorite”, a mineral that is found in the Upper Palatinate in Bavaria, Germany, have such an unpleasant sharp smell when it is crushed? Scientists in Munich have now found the solution to this puzzle, not only bringing an end to a controversial discussion that has been going on for about 200 years, but also altering a hard and fast textbook rule. In the journal Angewandte Chemie, the researchers have demonstrated that the stench is caused by elemental fluorine. This unambiguously proves that despite prior assumptions, elemental fluorine does occur in nature.
Our electronic devices are getting smaller and smaller while doing more and more. Using conventional materials, we will soon reach the practical limit. The electronics of tomorrow require alternatives, such as nanowires made of DNA that can serve as conductive paths and nanotransistors for miniature circuits. In the journal Angewandte Chemie, German scientists have now described a new method for the production of stable, conducting DNA nanowires.
Healing Bullets Fly Through Tissue: Ultrasound vaporization of microdroplets as propulsion for therapeutic micromachines
Microscopically small submarines that can swim through our blood to clear out clogged arteries or destroy malignant tumors. This concept may sound utopian, but it isn’t. Various micro- and nanomachines have in fact already been developed. In the journal Angewandte Chemie, American researchers have now introduced a new type of machine that finally has enough propulsive power to penetrate tissue and overcome cellular barriers.
Wiley annouces the publication of the only reference available that gives a thorough overview of all the important current methods used in Physical Chemistry.
Complex laboratory investigations do produce reliable results, but they are not useful for point-of-care diagnostics. This is especially true in developing countries, which must rely on simple, inexpensive test methods that do not require a power source. Biosensors based on paper are an interesting alternative. American researchers from the University of Texas at Austin and the University of Illinois at Urbana-Champaign have now introduced a particularly clever concept in the journal Angewandte Chemie: print on one side of the paper, fold it up origami-style, laminate it, and the test is ready. Test evaluation requires only a voltmeter.
The ultimate handbook on microcirculation imaging techniques
Painkiller by Photosynthesis. Selective and effective: silicon nanowires as photoelectrodes for carbon dioxide fixation
During photosynthesis, plants capture solar energy and use it to drive chemical reactions. Their carbon source is the CO2 in air. In the journal Angewandte Chemie, American scientists have now proposed a new reaction mechanism that binds CO2 and strongly resembles photosynthesis. In this process, light energy is captured by silicon nanowires. It was successfully used to synthesize two precursors of the anti-inflammatory, pain reducing drugs ibuprofen and naproxen.
Many discoveries are made by chance, but it is also possible to help it along: The chance of finding something interesting increases when the number of experiments rises. French researchers have now applied this principle to the search for new chemical reactions. In the journal Angewandte Chemie, they have introduced a new concept based on antibodies and a “sandwich” immunoassay.
Synthetic Scent Hounds: Nanostructured sensor for the detection of very low concentrations of explosive
To prevent terrorist attacks at airports, it would be helpful to detect extremely low concentrations of explosives easily and reliably. Despite the development of various sensor technologies, dogs continue to be the most efficient detectors. In the journal Angewandte Chemie, a German and French team has now described a type of micromechanical sensor with a structure derived from the sense organs of butterflies.
The term ethylene (ethene) generally brings to mind polyethylene plastics, not fruit. However, ethylene is more than just a feedstock for chemical industry, it is also the smallest plant hormone, and it controls physiological processes, such as the ripening of fruit, seed germination, and the blooming and wilting of blossoms. In the journal Angewandte Chemie, American researchers have now introduced a highly sensitive ethylene sensor that could be used to determine the ripeness of fruit.
In the book “Harry Potter and the Chamber of Secrets” by J. K. Rowling, Harry writes a question in Tom Riddle’s diary—and a written answer appears. Australian researchers were inspired by the idea of paper that writes on itself. In the journal Angewandte Chemie, they have introduced a blood test that indicates blood type in plain text.
Simulated Digestion: Nanomaterial made from lipids and silicon dioxide improves absorption of pharmaceuticals
Some medicines have to be taken either before, after, or during a meal because food ingredients can affect its absorption or bioavailability. Australian researchers have now encapsulated drugs in a matrix of silicon dioxide and lipids to simulate the administration of pharmaceuticals with food. As the researchers report in the journal Angewandte Chemie, drug absorption is increased through control of the enzymatic digestion of the lipid droplets.
The First Seconds in a Building’s Life: X-ray diffraction studies of cement hydration on the millisecond scale
No matter if it is a giant complex, a high-rise, or an underground project, modern architecture cannot get along without concrete. The component in concrete that holds the other components together is cement. In order to control the properties of concrete, it is important to know what occurs as it hardens. German scientists have now successfully watched the first few seconds in the “life” of cement by means of X-ray diffraction. In the journal Angewandte Chemie, they explain the role of the superplasticizers added to concrete.
Wiley is pleased to announce publication of a new major reference work, the Wiley Encyclopedia of Composites, 5 Volume Set, 2nd Edition
Improved Mussel Adhesive. Biocompatible, waterproof, self-healing, and reversible: A new adhesive for medical applications?
Mussels are true masters of adhesion. They bond solidly under water to nearly any type of surface. Researchers from Mainz have been inspired by mussel adhesive proteins to add another exciting property. As they report in the journal Angewandte Chemie, their new adhesive can be debonded on demand.
