The concept for a turbomolecular vacuum pump is based on a very basic principle: mechanical motion can be transferred directly to gas molecules to create a vacuum. This idea, which was first implemented by molecular drag pumps in the 1930s and 1940s and later refined in the first turbomolecular pump in 1958, has been so effective that few other solutions exist to provide this high level of vacuum performance in such a compact space.
In the last 10 years, the presence of wireless technology has blossomed in the industrial and manufacturing space, where a multitude of technologies, from Bluetooth to Zigbee to RFID, have been successfully employed to monitor conditions of machinery, products under assembly and the work force.
The ability to adapt to changing situations is critical for today’s labs. Today, many lab equipment systems are designed with the flexibility to accommodate these needs. Time is also of utmost importance, and the ability for a researcher to walk away from their work, or monitor it on the go, is a new standard.
Upon introducing engineering simulation into an organization, it’s important to formulate an implementation plan. Simply telling the engineering team to “have at it” doesn’t generally lead to positive results. Every plan will be different, but all can benefit from some basic considerations.
Investigations into long-term health consequences associated with pipetting were first made in the 1980s. Today, pipettes are typically designed with ergonomics in mind—but the right solution for one may not be the right solution for all. Considering body type and workstation design, in addition to pipette features, can result in greater ease, fewer errors and better throughput.
Before 2004, when Geim and Novoselov demonstrated the existence of graphene, a single-atomic-layer-thick crystal of carbon, physicists didn’t believe such a substance could exist. Since then, graphene has attracted tremendous research interest because of its exceptional physical and electrical properties.
After another year of flat spending in 2013, global investment in R&D is forecast to grow by 3.8% to $1.6 trillion in 2014, according the annual R&D Magazine Global Funding Forecast. In the U.S., federal spending is forecast to increase modestly (1.5%), another promising sign, but it’s fair to say the pressure is still on to do more with less, particularly in Big Pharma where recent R&D cuts have been the most dramatic.
Pharmaceutical companies are constantly seeking ways to improve efficiency in order to increase productivity, all while speeding up innovation and protecting intellectual property (IP). The use of mobile applications (apps) in the laboratory has been investigated as a means to achieve these goals. By allowing scientists to move freely around the laboratory, mobile apps add value to suboptimal processes requiring non-value-added steps.
High-speed rail is a frequently discussed topic, but one that has yet to become a reality in the U.S. A number of states and regions in the U.S. including Texas, California, the Pacific Northwest and Minnesota, to name a few, have planned projects to bring high-speed rail to fruition.
If a senior engineer left an organization suddenly, how many hours would it take for the engineering team to take over his projects, confident that they understand not only the designs, but why those designs are the way they are? The typical answer is “far too many”. Widespread use of CAE and data management tools have made this task much easier than before, but these tools do little to record the thinking behind the results.
Fluorescent proteins have helped researchers open doors to countless molecular imaging applications and deepened our understanding of biological processes. Without fluorescence, advancements in oncology, drug discovery and any field that requires single-cell to whole-body imaging would be substantially limited.
Rechargeable lithium-ion batteries are key components for portable electronics, medical devices, industrial equipment and automobiles. They are light weight, provide high energy density and recharge without memory effects. Much research has been spent on improving product safety, lifecycle and power output over a range of high and low temperatures, yet understanding fundamental processes and degradation mechanism remains a challenge.
All types of research laboratories rely on a set of core utilities to enable and support work functions. These are often overlooked as a commodity called “consumables”, but in reality they are indispensable nutrients that vary greatly in quality and reliability. Just as a human can’t exist without water, oxygen and food, the research facility cannot make do without water, gas, air, lighting and, increasingly, high-throughput data.
Spectroscopy is an analytical technique used to identify and determine the physical characteristics of materials through the measurement of emissions and absorption of electromagnetic spectra. A staple in any research laboratory, the technique makes its main home in pharmaceutical, biotechnology and chemical laboratories.
In today’s fast-paced markets, engineers are continuously challenged to deliver products that meet market demand, improve operational efficiency and exceed customer expectations. Multiphysics simulation is an essential component of the product design workflow for creating innovative designs, especially when building prototypes becomes impractical or when taking actual measurements is not possible.
