 | | |  Kinectics of Photocatalysis Reactions Studied by Transient Absorption Spectroscopy
Photocatalysis is the rate increase of a chemical reaction by light, often in the presence of a catalyst that starts the reaction upon irradiation. Photocatalysts are typically semiconducting metal oxides which are employed as particles in solution. When absorbing light they can generate electrons and holes which go on to react with chemical species on their surface.

| | |  A startling new study published in the journal Science shows that ultrasound can help scientists to understand whether specific genes are in the active or inactive state in live cells. This incredible feat promises to transform the way scientists examine a host of living cell activities, ranging from the growth of tumors to neuron function. | | | | |  n order to treat diseases better, we must understand how they arise. A European research team led by Prof. Christian Eggeling from the Friedrich Schiller University Jena, the Leibniz Institute of Photonic Technology (Leibniz IPHT), and the University of Oxford has now succeeded in using high-resolution imaging to make visible to the millisecond how the HI virus spreads between living cells and which molecules it requires for this purpose. | | | | |  A team of Tufts University-led researchers has developed three-dimensional human tissue culture models of pediatric and adult brain cancers in a brain-mimicking microenvironment, a significant advancement for the study of brain tumor biology and pharmacological response. | |
