Building calibration data takes effort, which is why many laboratories stay with older monochromator-based near-infrared (NIR) instruments instead of upgrading to more accurate Fourier transform-based systems (FT-NIR). A recent white paper from Bruker Optics details the possibility of transferring old calibrations from a monochromator system to an FT-NIR system such as Bruker's MPA.
Bruker Optics has published a method for on-line monitoring of edible fats and oils. Iodine value is important to these substances because it affects the viscosity and susceptibility to oxidation. Performed by a Fourier transform near-infrared spectrometer coupled with specially designed fiber optic probes, the methodology described in a recent Bruker Optics white paper speeds up analysis, reduces production down time, and achieves product consistency.
Konrad Juethner, a software engineering consultant, recently used Windows HPC Server to run cluster-based analysis with COMSOL Multiphysics using the hardware he had available at home. His successful setup highlights a high level of accessibility for advanced supercomputing approaches.
PerkinElmer technologists Andrew W. Salamon, Patrick Courtney and Ian Shuttler have authored a white paper that takes a comprehensive look at the quickly changing field of a engineered nanomaterials. They examine the materials now available, some of their potential applications, and the analytical instruments and techniques used to work with them.
Ajinomoto Aminoscience has announced availability of a new white paper that outlines the common challenges associated with recombinant protein production and discusses how new expression systems are helping simplify the production process, reduce costs, and speed time to market.
A new white paper from W. L. Gore & Associates, Inc., presents a systematic approach that design engineers can follow to ensure that a cable system will provide reliable performance in demanding environments and mission-critical applications.
Piezo technology specialist PI Ceramic has released a new white paper on the development and test of highly reliable multilayer piezo actuators. Because of their speed and precision, piezoelectric multilayer actuators are a driving force behind challenging motion control applications.
About 40,000 companies received questionnaires from the National Science Foundation and the U.S. Census Bureau in 2008. The results from this report, the first of its kind to gauge R&D performance on a global scale, show that the U.S. economy supports a higher level of domestic R&D ($234 billion) than some had thought.
W. L. Gore & Associates, Inc. (Gore) has announced results of a study in which they compared the measurement uncertainty between vector network analyzers and time domain reflectometers. They designed an experiment which determined if both instruments possess similar levels of measurement precision.
The authors of a new report from the Woodrow Wilson International Center for Scholars claim that the ability to estimate the social, ethical, legal, and economic impacts of emerging technologies and science is missing from our national perspective. They advocate the creation of a new institution that would assess national technology capability.
Microfuge tubes, one of the most common labware tools in molecular biology labs, have an Achilles’ heel. The way they are manufactured, a recent study finds, could be leading to measurement errors for researchers. Texas State Univ. researchers say the trouble stems from UV light-absorbing chemicals in polypropylene microtubes.
How many gallons of water does it take to produce $1 worth of sugar, dog and cat food, or milk? The answers appear in ACS' Environmental Science & Technology in the first comprehensive study in 30 years documenting American industry's thirst for this precious resource.
Active vibration isolation technology is a key ingredient for enabling next-generation, 22-nm scale lithography. In this white paper, PI describes the application of STACIS active isolators, which are now available in small form-factors, to advanced microscopies and nanomanufacturing.
The American Chemical Society has made public a recent study by Kuwaiti scientists in the journal Energy & Fuels that predicts world conventional crude oil production will peak in 2014. This is about 10 years earlier than other forecasts, particularly the Hubbert model, which accurately predicted peak production in the U.S. in 1970.
This paper presents a new design for a linear ultrasonic piezo motor for precision positioning developed by Physik Instrumente (PI). The design and operating characteristics of the prototypes are presented in both open- and closed-loop modes, and FEM software was used to obtain proper stator geometry.
