AXT Pty. Ltd., Australia, launched a new website dedi-
cated to x-ray tubes. The site focuses on replacement
x-ray tubes for analytical, industrial, and medical appli-
cations. AXT supplies tubes from various manufacturers
for a range of applications such as x-ray diffraction, x-ray
fluorescence, nondestructive testing including baggage
inspection, and many others. The site contains detailed
information about these applications as well as the var-
ious x-ray tubes that are available as replacement parts
for leading x-ray instrument manufacturers such as
Bruker, Thermo, Shimadzu, and PANalytical.

PI (Physik Instrumente), Germany, introduced a new
P-763 XY nanopositioning stage, an affordable piezo
stage positioner. The
compact P-763 flexure-
guided stage has a
footprint of less than
3 × 3 in. (70 × 70 mm)
while providing a
30 × 30 mm aperture.
With a travel range of
200 × 200 µm, the piezo positioning system is suitable
for demanding applications such as image stabilization,
microlithography, nano-alignment, surface metrology,
super-resolution microscopy and bio-nanotechnology,
and photonics and datacomm. .
The Emax from Retsch, Germany, is a new type of ball
mill for high energy milling. The combination of high fric-
tion and impact results in extremely fine particles
within a short amount of time. High energy input
is a result of a speed of 2000 min-1 and innova-
tive jar design. Thanks to the revolutionary
water cooling system, high energy input is
effectively used for grinding without over-
heating the sample. Due to the special
grinding jar geometry, samples are thor-
oughly mixed resulting in a narrow particle
size distribution. .
Bruker Corp., Billerica, Mass., introduced the SkyScan
TM 2211, a new high-resolution x-ray nano-CT (com-
puted tomography) system with a wide range of ob-
ject sizes and spatial resolutions. The system is
capable of nondestructive scanning and 3D recon-
struction of internal microstructures of large objects, as
well as submicron resolution for small samples. Sky-
Scan TM 2211 allows scanning objects up to 200 mm
in diameter, where high accuracy
of <50 nm for samples up to 25 kg
is achieved by high-precision air-
bearing rotation. Combining a 600-
nm c-ray source with two c-ray
detectors—a 3Mp flat-panel and
an 11 Mp cooled CCD detector—
8000 × 8000 × 2300 pixels can be
reconstructed after a single scan. The smallest de-
tectable detail (smallest pixel size) is 100 nm.
Materion Performance Alloys, Mayfield Heights, Ohio,
added nickel aluminum bronze (AMS 4881 C95520) con-
tinuous cast hollow bars to its line of high performance
alloys. AMS 4881 C95520 is a martensitic nickel alu-
minum bronze that offers higher strength and hardness
than other nickel aluminum bronze alloys. Using
patented technology called EquaCAST, an extremely
uniform, fine-grained microstructure with more consis-
tent mechanical properties is produced with better
machinability to ensure surface finish. AMS 4881
C95520 is used primarily for aircraft landing gear and
brake systems as well as heavy equipment bearings,
bushings and wear plates, and oil and gas components.

Instron, Norwood, Mass., offers VisualRHEO software,
which manages and analyzes data from rheological
tests with steps at constant piston speed or shear rate,
enables full control over gathering data including viscos-
ity, Bagley, and Rabinowitsch corrections, and
non-Newtonian index calculations. Software
is compatible with Windows 2000/XP/
Vista/7/8.1 and features a real-time graphic
display of the measured quantity; post-
process graphs of rheological quantities
(apparent and corrected values); password-
protected operator
access levels; ability
to export to spread-
sheets, text files, and
LIMS systems; test
comparison and refer-
ence viscosity curves; and an advanced
database search. .
Agilent Technologies Inc., Santa Clara, Calif., introduced
its AFM-enabled scanning electrochemical mi-
croscopy (SECM) mode, a seamlessly integrated tech-
nology package that enables scientists to perform
scanning electrochemical microscopy on conductive
and insulating samples. This unique mode of AFM oper-
ation allows scanning electrochemical microscopy to be
performed quickly and reliably with nanoscale resolution.
The SECM mode can be used to investigate homoge-
neous and heterogeneous electron transfer reactions,
image biologically active processes, analyze thin films
(e.g., pinhole detection, conformality), screen catalytic
material (e.g., fuel cell catalysts), and study corrosion
processes. .
FEI, Hillsboro, Ore., introduced the NanoEx sample
holder for in situ transmission electron microscopy
(TEM). Its use of an innovative micro-electro-mechani-
cal system (MEMS)-based heating element enables
