It has long been well established that fingerprints can be used to identify people or help convict them of crimes. Things have gone a lot further now: fingerprints can be used to show that a suspect is a smoker, takes drugs, or has handled explosives, among other things. In the journal Angewandte Chemie, Pompi Hazarika and David Russell describe the noteworthy progress that has recently been made.
Wiley-VCH, part of the scientific and technical publishing business of John Wiley & Sons, Inc., and the Asian Chemical Editorial Society (ACES) today announced the launch of the Asian Journal of Organic Chemistry, the second pan-Asia society chemistry journal after Chemistry – An Asian Journal (2010 Impact Factor: 4.188), launched by ACES and Wiley-VCH in 2006.
The future will be dominated by organic electronics, as opposed to current silicon-based technology. In the journal Angewandte Chemie, an international team of researchers has now introduced a new luminescent organic liquid that can be applied like ink. When two additional dyes are dissolved in this liquid, it forms a white luminescent paste that may offer a new way to make devices like large displays and white light-emitting diodes.
Dr. Vera Köster, Website & Managing Editor, Wiley-VCH, is the recipient of this year’s prize of the Society of German Chemists (GDCh) for journalists and writers.
It is not always easy to distinguish between images and mirror images of molecules, but this knowledge is important when one image of a molecule is a drug and the mirror image is toxic. One new approach to this may be chiral recognition in the gas phase. This involves using synchrotron radiation (highly energetic photons from a particle accelerator) to eject electrons from the molecules and analyzing their trajectories. In the journal Angewandte Chemie, German researchers have now demonstrated that such experiments also work with a compact laser system.
Finding Cancer Cells in Blood. Chip-based method for the rapid, sensitive isolation of rare cells in blood
Even in the early stages of cancer, individual cancer cells can be found in the blood. Certain subsets of these circulating tumor cells can cause metastasis. In cases of breast cancer, it is known that these cells can differ from the original tumor cells, which allows them to survive treatment to cause later recurrence. It could thus be quite informative to detect these cells in the blood and examine them more closely. In the journal Angewandte Chemie, researchers at the University of Washington (Seattle, USA) describe a new chip-based method that allows for the detection and isolation of tiny concentrations of such cells in blood.
In 2012 Wiley-Blackwell, the Scientific, Technical, Medical, and Scholarly publishing business of John Wiley & Sons, Inc., will begin publishing 44 titles new to its journal program, including 16 new launches and 40 journals published in collaboration with societies or other organizations.
Phosphorus and arsenic are on top of each other in one group of the periodic table, so they have many similar properties. In addition to tubular forms, phosphorus is found in white, red, black, and purple structural forms. At room temperature, black phosphorus is the stable form; the others are metastable. According to textbooks, arsenic occurs in gray, yellow, and black forms. However, the existence of black arsenic, which should be analogous to black phosphorus, has never been indisputably proven. In the journal Angewandte Chemie, German researchers have now demonstrated that black arsenic is metastable in its pure form, and that it has thus far only been obtained in a form stabilized by atoms of other elements.
Tiny Silver Particles Trap Mercury. Hyperstoichiometric reaction between mercury ions and silver nanoparticles
Anyone who thinks amalgams are limited to tooth fillings is missing something: Amalgams, which are alloys of mercury and other metals, have been used for over 2500 years in the production of jewelry and for the extraction of metals like silver and gold in mining operations. These days, the inverse process is of greater interest: the removal of mercury from wastewater by amalgamation with precious metals in the form of nanoparticles. Kseniia Katok and colleagues have now reported new insights in the journal Angewandte Chemie: if the diameter of silver nanoparticles is made even smaller, significantly more mercury can be extracted relative to the amount of silver used.
Wiley titles have been honored with 11 prizes at the 2011 PROSE Awards.
Packaging, insulation, and impact protection are examples of commercial uses of polymer foams. Depending on the intended application, the properties required of these foams can differ greatly. In the journal Angewandte Chemie, a team of German, Irish, and French researchers led by Cosima Stubenrauch at the University of Stuttgart has now introduced a new method for the controlled production of structured foams. Their technique is based on the polymerization of foamed emulsions of oil in water.
DNA is not merely a carrier of genetic information; DNA is a useful building material for nanoscale structures. In a way similar to origami, the Japanese art of paper folding, a long single strand of DNA can be folded into nearly any three-dimensional shape desired with the use of short DNA fragments. The DNA nanostructure can also be equipped with specific docking sites for proteins. In the journal Angewandte Chemie, a team led by Takashi Morii at the University of Kyoto (Japan) has now introduced a new method for attaching the proteins by means of special “adapters” known as zinc-finger proteins.
Was the consumption of toxic mushrooms responsible for a series of unusual deaths in China’s Yunnan province? A team led by Ji-Kai Liu (Beijing) has now found further proof of this hypothesis. In the journal Angewandte Chemie, the researchers now present two unusual toxic amino acids that they found in extracts from the suspect mushrooms.
Delicate and translucent as a puff of air, yet mechanically stable, flexible, and possessing amazing heat-insulation properties—these are the properties of a new aerogel made of cellulose and silica gel. Researchers led by Jie Cai have introduced this novel material, which consists almost completely of air, in the journal Angewandte Chemie.
Precious metals, especially platinum, are important catalytic materials for many chemical reactions. For example, platinum is used in some fuel cells; however, broad commercialization of such fuel-cell technology is hampered by the fact that platinum is rare and thus far too expensive. Growing demand is making it necessary to develop efficient and environmentally friendly processes for recycling platinum. Jing-Fang Huang and Hao-Yuan Chen at the National Chung Hsing University in Taiwan have now introduced a new approach in the journal Angewandte Chemie. Their method is based on the dissolution of the metal in an ionic liquid.
Archaeologists examining late period Mayan containers have identified nicotine traces from a codex-style flask, revealing the first physical evidence of tobacco use by ancient Mayans.
New research into the potential link between parabens and breast cancer has found traces of the chemicals in breast tissue samples from all of the women in the study. Parabens are commonly used as preservatives in cosmetics, food products and pharmaceuticals. As the research shows that parabens are measurable in the tissue of women who do not use underarm cosmetics the parabens must enter the breast from other sources.
Whether it’s right under our nose or far away, when we observe an object we see it—provided we have healthy eyes and normal vision or suitable glasses—in focus. For this to work, muscles deform the lenses of our eyes and adjust them to a suitable focal distance. For miniaturized technical devices, microscale lenses with a similar adaptable focus could be an advantage. In the journal Angewandte Chemie, Hong-Bo Sun and a team from Jilin University (China) have described a new approach to the production of adjustable microlenses made from protein gels.
Wiley-VCH, part of the scientific and technical publishing business of John Wiley & Sons, Inc., and ChemPubSoc Europe, an association of 16 chemical societies, have announced the launch of ChemPlusChem, a multidisciplinary journal centering on chemistry.
