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.
Naomi Ginsberg, a chemist at Berkeley Lab, is leading the development of CLAIRE (short for "cathodoluminescence activated imaging by resonant energy transfer"). This modality is a non-invasive means for obtaining images of soft matter, and is less destructive of materials than traditional EM methods. CLAIRE uses an electron beam to pass through scintillating film and hit the sample, then creates an image from the luminescence emitted by the sample. Ginsberg states the group is hopeful CLAIRE will be useful in more applications, like watching crystallization or processes in membrane biophysics.
Product and Company
As of June 1 2015 the Olympus Soft Imaging Solutions (OSIS) GmbH EMIC product group will be taken over by EMSIS GmbH, a new start-up with decades of experience in electron microscopy.
The new NordlysMax3 electron back scatter detector from Oxford Instruments has almost double the rate of aquisition over the previous model.
The super-resolution K2 Summit camera for cryo-electron microscopy uses electron counting to record the highest resolution images with the lowest noise. This technology has enabled researchers to determine protein structures at 2.8 Å resolution and protective antigen pore structure at 2.9 Å resolution using single particle cryo-EM.
TESCAN has introduced a coherence-controlled holographic microscope for quantitative phase imaging of biological specimen. This expands Tescan's product line into the advanced light microscopy.
Quotes / About Microscopy and From Microscopists
"It is my intention to offer a prize of $1,000 to the first guy who can take the information on the page of a book and put it on an area 1/25,000 smaller in linear scale in such manner that it can be read by an electron microscope. "
"...a lot of people will advise you. On the one hand you want to listen, and on the other hand you want to test it and say, ‘Okay, is this really making sense, or is it just that somebody I really respect said this?’”"
"Scan not a friend with a microscopic glass
You know his faults, now let his foibles pass"
"Once you add a computer between the microscope and the human observer, the whole game changes. At that point a microscope is no longer a device that has to generate a directly interpretable image. Now it's a device to record information."
