The organic solar cell (OSC) heterojunction interface is where key photophysical processes such as charge separation and recombination occur. The molecular orientation at the interface is one of the key factors that determine the efficiency of solar cells. Due to the complex three-dimensional ...
“We were surprised how powerful this new tool is, considering how straightforward it is to assemble”
Researchers have made a tiny camera, held together with ‘molecular glue’ that allows them to observe chemical reactions in real time. The device, made by a team from the University of Cambridge, combines tiny semiconductor nanocrystals called quantum dots and gold nanoparticles using molecular ...
Interference leads to inaccurate Raman spectroscopic analysis of vitamin B12
Many natural products are complicated organic molecules. Despite this complexity, scientists are usually able to investigate them using spectroscopic techniques. However, a team of researchers has now discovered that care should be taken using Raman spectroscopy to analyze certain chiral ...
Ultrafast charge transfer in Prussian blue analogues
Photoinduced charge transfers are an interesting electronic property of Prussian blue and some analogously structured compounds. A team of researchers has now been able to elucidate the ultrafast processes in the light-induced charge transfer between iron and manganese in a manganese-containing ...
Completely unusual and never observed like this before
An international team has observed an amazing phenomenon in a nickel oxide material during cooling: Instead of freezing, certain fluctuations actually increase as the temperature drops. Nickel oxide is a model system that is structurally similar to high-temperature superconductors. The experiment ...
Many scientific experiments require highly precise time measurements with the help of a clearly defined frequency. Now, a new approach allows the direct comparison of frequency measurements in the lab with the atomic clock in Bern, Switzerland. For many scientific experiments, today’s researchers ...
A new method for identifying quantum orbits enables photoelectron spectroscopy via tunneling ionization to provide attosecond temporal and subangstrom spatial resolution measurement of electron dynamics
Electron motion in atoms and molecules is of fundamental importance to many physical, biological, and chemical processes. Exploring electron dynamics within atoms and molecules is essential for understanding and manipulating these phenomena. Pump-probe spectroscopy is the conventional technique. ...
The Körber European Science Prize 2021 awarded to chemist Clare Grey
The Körber European Science Prize 2021, endowed with one million euros, goes to Clare Grey. The British chemist pioneered the optimisation of batteries using NMR spectroscopy. Grey pioneered the optimisation of batteries with the help of NMR spectroscopy. This method allows non-invasive insights ...
Researchers at Tampere University and their collaborators have shown how spectroscopic measurements can be made much faster. By correlating polarization to the colour of a pulsed laser, the team can track changes in the spectrum of the light by simple and extremely fast polarization measurements. ...
Novel spectroscopic technique developed
In a joint experimental and theoretical effort between Lund University (Sweden), the Russian Academy of Science (Russia), and the Center for Advancing Electronics Dresden at Technische Universität Dresden (Germany), researchers developed a novel spectroscopic technique for the study of charge ...
