Advanced Light Source Sets Microscopy Record

A record-setting X-ray microscopy experiment may have ushered in a new era for nanoscale imaging. Working at the U.S. Department of Energy (DOE)’s Lawrence Berkeley National Laboratory (Berkeley Lab), a collaboration of researchers used low energy or “soft” X-rays to image structures only five nanometers in size. This resolution, obtained at Berkeley Lab’s Advanced Light Source (ALS), a DOE Office of Science User Facility, is the highest ever achieved with X-ray microscopy.

Using ptychography, a coherent diffractive imaging technique based on high-performance scanning transmission X-ray microscopy (STXM), the collaboration was able to map the chemical composition of lithium iron phosphate nanocrystals after partial dilithiation. The results yielded important new insights into a material of high interest for electrochemical energy storage.

Product of Interest

Scientific Industries Roto-Shake Genie

Roto Shake Genie® is a combination platform/tilt, shaker, rocker, and specialized rotator mixes tubes 6 different ways: rotating, rocking/ shaking, rotating/rocking, rolling/rocking and rotating/ rolling, as well as a combination of all these mixing actions. An optional 3-D Orbital Shaker Attachment transforms the unit into an orbital shaker. Easy to remove, two-sided 8” x 13.5” (20.3cm x 34.3cm) stainless steel magnetic platform easily converts from rotating to rocking with a simple mechanical adjustment.

 Coy Laboratory Products O2 Control Glove Boxes and Cabinets

The importance oxygen levels play in various biological processes is increasingly significant to researchers. To study this requires consistent atmospheric control — maintaining hypoxia, normoxia, hyperoxia, or anoxia to mimic physiological conditions. Coy offers a complete line of glove boxes and cabinets that enable you to maintain desired levels of CO2, temperature and humidity, along with oxygen control.

Help your Colleagues

Plenty of discussions are happening on LabWrench all the time. We have many questions come in daily from users that are seeking advice from fellow users and lab professionals on LabWrench. Can you help any of these users find the answers they are looking for?

Circuit Board
I recently acquired a Labophot 2 but the circuit board for the lamp has died. Nikon tells me I need the old style 'large' circuit board. My circuit board is marked HSV-6-30NC and has the electrolytic cans vertically placed on the board not horizontally like the newer 2-piece board. Can someone help me with finding a replacement board? Advise this member.

Phosphor Screen
Can someone please tell me the typical response time (rise time and decay time) of the green phosphor screen in JEOL 2100F TEM? Thank you for your help. Advise this member.

Microscope stage is dropping down
When lifting the microscope stage with the coarse focus knob, at a certain point it drops down undamped all the way, slamming the condenser into the light source. Does this mean that the focussing mechanism is broken, or is there any way to adjust it to prevent this? Advise this member.

Company News Hot Off The Press

Leica Microsystems Introduces the Inverted Microscope Leica DMi8
Wetzlar, Germany. Leica Microsystems is launching the Leica DMi8 inverted microscope with built-in modularity that can grow and adapt to ever-changing research needs. With this new concept, life scientists can custom-configure an inverted microscope now and upgrade it in the future for applications ranging from basic imaging to advanced fluorescence microscopy. The Leica DMi8 is equipped with an additional incident illumination port, the Infinity Port, which facilitates the integration of additional light sources and laser systems for advanced applications.

Market launch of ZEISS Smartzoom 5 
The Microscopy business group of ZEISS will present its first automated digital microscope. The device particularly stands out thanks to its one-of-a-kind operating concept, which makes operation as easy as possible for the user. In an industrial environment, optical inspection is an important part of production-related quality testing. Parts such as screws, printed circuit boards, and metal elements need to be examined for defects. Read more.


FEI adds Phase Plate Technology and Titan Halo TEM to its Structural Biology Product Portfolio
FEI announced two new products for cryo-electron microscopy applications: a new phase plate solution and the Titan Halo™ transmission electron microscope (TEM). The phase plate is a stable, durable solution to increase the contrast of sensitive biological samples and is available on most TEM platforms from FEI. The Titan Halo TEM provides high-quality optical performance with enhanced flexibility for multi-scale applications in life and biomaterials sciences. Read more.

Questions from the Vault

We have so many questions filling our forums that sometimes questions can be missed and go without answers. Can you help us provide answers for these users with unanswered questions?

Nikon Eclipse 80i
There are dark spots in field when I use filters, in bright field no problem. I checked all filters and lenses every thing is fine. Please help. Advise this member.

E beam spot size
What is the spot size for the electron beam at 10 kV and 250µA? Advise this member.

Filter Adjustment
I'm a user of JEOL 2200 FS with omega filter. I would appreciate if someone could tell me how to do EELS in TEM Mode ( at high magnification), should we correct stigmatism of Filter every time? Using alpha 3, spots 1 or 2 with ENTA aperture 4, to get better resolution, in SPECTROSCOPY mode the spot is always with a shadow ( long tail) unless I make the beam fully deconverged as I lose my signal even in ZLS. Does anyone have an idea on the reason of it? In alpha 1 it is even worse. Advise this member.
