- New phenomenon of radioactivity
Physicists at the TU Darmstadt have succeeded in observing an extremely rare radioactive decay for the first time ever. The unusual thing about it is that this so-called double gamma decay of an ex... - Observing one of the world's fastest chemical reactions using femtosecond spectroscopy
UV radiation often damages our DNA. Researchers at Kiel University and The University of Bristol, Great Britain, have now seen for the first time what happens in DNA building blocks when they are s... - Organic framework serves as a catalyst for the photocatalytic conversion of water into hydrogen
Humanity's need for energy is ever-increasing. However, the traditional energy sources are finite. In contrast, water and sunlight are available in vast abundance. Scientists at the Max Planck Inst... - New certificates for the series of uranium hexafluoride reference materials
Scientists from the JRC-Institute for Reference Materials and Measurements (IRMM) recharacterised and issued new certificates for the entire series of uranium hexafluoride certified reference mater... - Scientists developed a light-activated molecular motor
Molecular motors are synthetic chemical compounds that can convert externally supplied energy into mechanical motion. Such molecules, which are specifically designed to execute directional movement... - Proteins from rice - raw materials instead of waste
Proteins remain after starch is extracted from rice. Until now, this valuable raw material was disposed of by rice starch producers at great expense. A new process is being developed to split prote... - New family of chemical structures can effectively remove CO2 from gas mixtures
The zeolites - crystalline aluminosilicates with frameworks that contain windows and cavities the size of small molecules - can separate out carbon dioxide more effectively from fuel gases than tho... - How to improve ultrathin CIGSe solar cells by nanoparticles
CIGSe solar cells are made of a thin chalcopyrite layer consisting of Copper, Indium, Gallium and Selenium and can reach high efficiencies. Since Indium is becoming scarce and expensive, it is int... - Nanocarbons clean water without the use of chemicals and transform waste heat into electricity
Scientists at Leibniz Institute for New Materials INM are working on a desalination method which does not require the addition of chemicals and which is highly energy-efficient. This environmentall... - Observing the motion of a protein in a crystal
X-ray crystallography reveals the three-dimensional structure of a molecule, thus making it possible to understand how it works and potentially use this knowledge to subsequently modulate its activ... - Rapid analysis of kidney stones using Raman spectrosopy
Kidney stones rank among the most common illnesses. Their recurrence might be prevented with the right postoperative care. However, for this to be effective, composition of the stones should be kno... - High-speed electron tomography sets new standards for 3D images of the nanoworld
Scientists from the Ernst Ruska-Centre in Forschungszentrum Jülich used a transmission electron microscope to record almost 3500 images in 3.5 seconds for the reconstruction of a 3D electron tomogr... - Rapid and efficient technique for targeted chemoenzymatic functionalization of proteins
Selective intermolecular recognition is at the heart of all biological processes. Thus proteins that bind specifically to complementary chemical structures are also indispensable for many biochemic... - Spin-Echo-Spectroscopy will enable most accurate neutron measurement yet
Our universe consists of significantly more matter than existing theories are able to explain. This is one of the great puzzles of modern science. One way to clarify this discrepancy is via the neu... - Protein reactions identified with combination of infrared spectroscopy and computer simulations
Using subatomic resolution, researchers have gained insights into the dynamic modus operandi of two switch proteins which are responsible for the import of compounds into the nucleus and for cell g... - Nobel Prize in Chemistry 2015: The cells' toolbox for DNA repair
The Royal Swedish Academy of Sciences has decided to award the Nobel Prize in Chemistry for 2015 to Tomas Lindahl, Francis Crick Institute and Clare Hall Laboratory, Hertfordshire, UK, Paul Modrich... - Novel porous materials called provides a basis for the design of polymeric photocatalysts
Chemical systems that are capable of generating hydrogen gas by light-activated scission of water molecules (often termed artificial photosynthesis) represent a promising technology for the efficie... - New method enables researchers to sequence complex sugar molecules for the first time
A team of researchers from Berlin succeeded in an effort to fundamentally improve carbohydrate analysis. With the new method, developed by Kevin Pagel (Free University Berlin and Fritz Haber Instit... - Real-time analysis of metabolic products
Biologists at ETH Zurich have developed a method that, for the first time, makes it possible to measure concentration changes of several hundred metabolic products simultaneously and almost in real... - Laser-optic measuring techniques to optimize diesel cat
The scandal surrounding VW has thrust nitric oxide (NOx) emissions from diesel vehicles into the limelight. Owing to the different engine technologies, these have always been higher than in gasolin... - Researchers develop ideal Single-Photon Source
With the help of a semiconductor quantum dot, physicists at the University of Basel have developed a new type of light source that emits single photons. For the first time, the researchers have man... - Chemistry for the methanol economy
Unstable crude oil prices and limited oil resources have made the production of petrochemicals from methanol increasingly popular - above all in China. Scientists at ETH Zurich have now deciphered ...
