Research and Innovations
Transient Absorption (TA) Microscopy couples ultrafast temporal resolution with high spatial resolution to obtain information on heterogeneous electronic properties across domains ranging from tens to hundreds of nanometers in size of organic photovoltaic films. The technique measures changes in adsorption spectra resulting from femtosecond laser pulses that have excited the transient energy states.
John Miao, a UCLA professor, and his colleagues have contributed an article to the May 2015 issue of Science, in which they review and analyze the wide range of applications that have stemmed from Miao's technique of coherent diffractive imaging (CDI). Developed in 1999, CDI uses an X-ray and a computational algorithm to interpret the diffraction pattern, instead of a lens. This allows users to achieve high-resolution, high-contrast imaging of nanoscale objects, and was the first method in X-ray crystallography to enable imaging of noncrystalline materials and nanocrystals.
The National Physical Laboratory (NPL) has developed a microscopic specimen that features single-nanometer spacings. These protein nanostructures would make an excellent material for calibration standards. EM users would be able to calibrate with greater reproducibility, accuracy, traceability and precision.
The Korea Advanced Institute of Science and Technology (KAIST) has published an article in Optics Express, the journal of the The Optical Society detailing a new microscope technique to identify bacteria more quickly. This simple modification to a traditional microscope could help in medical applications by eliminating the need to culture microbes prior to identification, and in food services applications to identify any pathogens. It works by using laser holographic techniques to identify single bacterial species, and uses mathematical and computer software with a machine-learning algorithm that is similar to that used for facial recognition in security cameras.
Product and Company
Hitachi High-Technologies Corporation will introduce its new instrument, the NX9000, at Microscopy & Microanalysis 2015 in Portland, U.S.A. from August 2-6, 2015. The NX9000 is the second product created through the collaboration of Hitachi High-Tech and its subsidiary Hitachi High-Tech Science Corporation. This real-time 3D analytical FIB*1-SEM*2 composite instrument boasts improved 3D structural analysis precision and throughput, and can be used in applications of SEM observation, 3D EBSD, 3D EDS, TEM or atom probe sample preparation, and more. By arranging the SEM column and FIB column orthogonally, instead of diagonally, the NX9000 is optimized for improved throughput and precision in 3D structural analysis applications.
Bruker has launched the OPTIMUS™ TKD detector head for use with scanning electron microscope. The head can be easily interchanged with Bruker e-Flash EBSD detectors, so users have access to Transmission Kikuchi Diffraction (TKD) and EBSD with the same detector. OPTIMUS™ TKD provides a simple, cost-effective method of obtaining Selected Area Electron Diffraction (SAED) patterns like those acquired through TEM, and can be integrated with the ARGUS™ direct electron detection system to allow for bright field and dark field images.
Leica Microsystems has launched the Leica DM2500 LED, completing the Leica DM1000 to 3000 series of microscopes. All the microscopes are available with an LED illumination feature, which keeps a constant color temperature. The DM2500 LED can be used for demanding applications in clinical labs, and research applications in cytology, developmental biology, microbiology, botany, and zoology, to name a few.
Quotes / About Microscopy and From Microscopists
"One story that the Prof.(Oakley) used to tell, is that when the SEM was being considered as a commercial product, a group of Marketing experts were sent out to make an evaluation of the number of SEMs that could be sold. ...they came back with probably between 6 (six), and 10 (ten) would saturate the market!"
"We replaced the wave length of the light by the wave length of electrons at an accelerating voltage of 75 kV and inserted into the Abbe relation the imaging accelerating voltage of 75 kV and inserted into the Abbe relation the imaging accelerating voltage of 75 kV and inserted into the Abbe relation the imaging aperture of 2 X 10-2 rad...we came up with a resolution limit of 2.2 Å ."
"Our work, it seems to me, can bring us a special bonus of pleasure and satisfaction, through its very close contact with colleagues of different disciplines and our ability to peep into the inexhaustible world of the smallest forms of existence..."
"There was no physical law to prevent it."
