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.
Fume hoods have been present within society and science since the 17th century. However, throughout the years fume hoods have changed to accommodate user’s needs and laboratory applications. While the first fume hoods were fixed and far from flexible, with modern and mobility needs, fume hoods have now become flexible in design, more efficient, energy-saving, and also now have many types from benchtop or conventional fume hoods, radioisotope fume hoods, perchloric fume hoods, ductless fume hoods, and more.
It is well known that laboratories and fume hoods are generally the largest consumers of energy in a facility. Since recycling exhaust air and intermittent HVAC equipment operation are not luxuries afforded in the operation of many labs and fume hoods, it is necessary to account for four specific areas when designing or retrofitting a system.
Camera systems and scanners must have high resolutions. This creates difficulties for all applications where low light intensity means neither the resolution of the chip nor the exposure time for changing or moving objects can be freely chosen. In a new paper, Physick Instrumente details how to increase the resolution of these sensor chips.
The DC-test results of PICMA actuators are the basis for lifetime calculations under predefined conditions. The individual factors which have an impact must be taken into consideration, such as temperature, relative humidity and applied voltage. PI gathered results through an extensive series of tests still in progress.
Physik Instrumente gives a detailed look at piezoelectric operationg and theory.
The Tormach PCNC 1100 was designed from the ground up to be a CNC mill that is affordable, portable, easy-to-use, and easy-to-maintain. With these attributes, the CNC mill becomes a valuable tool for prototyping, research and development, and education. Now, CNC is not limited to the professional machine shop – it can be used by engineers, inventors, researchers, students, and hobbyists as an at-the-ready “personal” manufacturing tool.
Many HPC IT departments are feeling the rising pressure to deliver more capacity computing and performance while trying to reduce the total cost of ownership. This white paper discusses how an environmentally-friendly and open-standards HPC building block based computing system using flexible interconnect options helps address capacity computing needs.
