The “Superresolution” research network, founded by the German Ministry of Education and Sciences, demonstrated a new widefield microscopy technology with resolutions better than 20 nanometers. The method is based on special dyes, which’s fluorescence can be optically and reversibly switched on and off in aqueous solutions. The dyes are bond to cellular structures by using a functional group. By switching the dyes on and off, the fluorescence emission is separated in time until only those dye molecules fluoresce that have enough distance to allow their localization as single molecules. After several thousand switching cycles, a total image is constructed (dSTORM – direct stochastic optical reconstruction microscopy). Involved in the project were the work groups of Prof. Dr. M. Sauer and Prof. Dr. J. Mattay (University of Bielefeld, Germany ), Prof. Dr. K.-H. Drexhage (University of Siegen, Germany), Prof. Dr. J. Enderlein (University of Goettingen, Germany), and Prof. Dr. S. Hell (Max Planck Institute of Biophysical Chemistry, Goettingen, Germany).

The Twelfth Frontiers of Electron Microscopy in Materials Science, FEMMS2009, will take place from Sept. 27 – Oct. 2, 2009 at “Huis Ten Bosch” in Sasebo/Nagasaki in Kyushu Island, Japan. FEMMS is an international a biennial symposium series focused on the application of electron microscopy, primarily TEM, in the field of materials science. The conference contains a plenary talk, 9 sessions of invited talks and poster sessions of contributed papers. The sessions cover recent progresses and emerging trends, such as current instrument advances in TEM, SEM, HVEM and detecting systems, ultra-high resolution imaging and analysis, in-situ and ultra-fast analysis, 3-dimensional analysis, and so on. Dr. Akira Tonomura, a world renowned pioneer in the field of electron holography, will give a plenary talk as the distinguished lectureship award winner.

Thermo Fisher Scientific will host a series of free informative seminars on routine spectroscopy in the analytical laboratory. This seminar will explain the range of spectroscopic techniques currently available for use in the quality control or analytical laboratory. The essential theory of Infra-Red, Near-Infra-Red, Raman and UV spectroscopy will be covered, together with how to select the best technique for a given process or application. The seminar is aimed at scientists and analysts looking to commission, expand or replace spectroscopic analytical capabilities in their laboratory.
June 2, 2009 – Hemel Hempstead, UK
June 3, 2009 – Leeds, UK
June 4, 2009 – Edinburgh, UK

A proposal by a team of UC Davis (University of California, US) scientists to develop the first electron microscope capable of filming live biological processes has been awarded a $2 million grant from the National Institutes of Health. The team’s plan is to extend the capabilities of a powerful new imaging tool called the dynamic transmission electron microscope or DTEM. These instruments can snap 10 to 100 images per millionth of a second, while capturing details as small as 10 nanometers. If they can be adapted to living, moving systems, DTEMs could achieve resolutions 100 times greater than currently attainable for live processes, enabling scientists to observe and record biological processes at the molecular level. Currently, there are only three DTEMs in use worldwide, none of which are designed for observing living systems. Rather, they are utilized to document such processes as inorganic chemical reactions and the dynamics of materials as they change from one state – solid, liquid or gas – to another.

The Photonics Festival is the integrated event comprising of the international trade shows of OPTO Taiwan, LED Lighting Taiwan, OPTICS Taiwan and SOLAR Taiwan, taking place concurrently together with Display Taiwan during June 10-12, 2009 at Taipei World Trade Center, Taipei, Taiwan. The Festival presents exhibitions and conferences on the latest technologies and products in the optoelectronics industry. It is open to manufacturers, suppliers and distributors in the industry who want to expand their overseas sales networks. The show has been held since 1984 and is an event for exchanging information, comparing products and services with competitors, and spotting future trends.
