Training of first responders on the hazards of actual radiological and nuclear threats has been challenged by the difficulties of adequately representing those threats. Training against such threats would involve using hazardous, highly radioactive materials, experiencing actual radiation doses in training, or require the distribution of radioactive material over a large geographical area.
It has been taken for granted for over 50 years that the type of spectroscopy widely used to study hydrogen inside materials is not subject to any selection rules. In the joint theoretical and experimental study that appeared recently in Physical Review Letters, an international team of researchers showed that this near universally held view is incorrect for at least one important class of hydrogen-entrapping compounds.
Foodborne illnesses kill roughly 3,000 Americans each year and about one in six are sickened, according to the Centers for Disease Control and Prevention. Yet most contaminated foods are never traced back to their source. That’s because existing methods to track tainted food following its supply chain from table to farm are highly inefficient, jeopardizing the health of millions and costing the food industry billions.
Dissecting neuron function, while crucially important for understanding normal and pathological neurological processes, requires measuring the responses of live cells to external stimuli. Because of the inherent difficulties in performing perturbation analyses inside living organisms, there has been a longstanding drive towards developing methodologies for in vitro analysis of neurons.
Lawrence Livermore National Laboratory researchers in conjunction with collaborators at Univ. of California, Los Angeles have found that some cells build intracellular compartments that allow the cell to store metals and maintain equilibrium. Nearly 40% of all proteins require metal ions such as zinc, copper, manganese or iron for activity.
One major challenge currently facing the graphene industry is difficulty in controlling the quality of graphene sheets when produced over large areas using industrial scale techniques. The key to solving this challenge lies in gaining a thorough understanding of the synthetic methods used to fabricate macro-sized single-layer graphene films.
Nearly half of all U.S. adults, nearly 117 million individuals, are living with one or more chronic health conditions. This has become the age of chronic disease, and achieving better outcomes depends on developing tools for research and clinical care that efficiently and accurately address the complex diseases we face today.
During the 2014 R&D 100 Awards event, R&D Magazine expanded the banquet to hold four technology panels during the day. The first panel focused on analytical instrumentation and the innovation behind four R&D 100-winning technologies and the complexity of bringing such instrumentation to the market.
Hydrocarbon exploration by definition is the search by geologists or geophysicists for hydrocarbon deposits beneath the Earth’s surface, such as oil (petroleum) and natural gas. In such exploration, the oil and gas industry drills holes into the Earth’s surface to extract the petroleum or natural gas. However, such exploration is expensive, not to mention a high-risk operation.
Researchers have combined key features of two highly acclaimed x-ray spectroscopy techniques into a new technique that offers sub-nanometer resolution of every chemical element to be found at heterogeneous interfaces, such as those in batteries and fuel cells. This new technique is called SWAPPS for Standing Wave Ambient Pressure Photoelectron Spectroscopy.
Fluorocarbon, a generic term for organic compounds with carbon-fluorine (C-F) bonding, is a chemical material used as a refrigerant in refrigerators and freezers and air conditioners in cars, buses, other vehicles and buildings. It’s also used as a cleaning agent for electronic components and precision parts.
Near-infrared (NIR) spectrometers have been around for over 60 years, yet only a small fraction of the population is familiar with these dependable tools. It’s astounding that NIR spectroscopy does so much for so many people who have never heard the word “spectrometer.” NIR spectrometers help a diverse set of users make decisions in their daily jobs.
The “surfactant” chemicals found in samples of fracking fluid collected in five states were no more toxic than substances commonly found in homes, according to a first-of-its-kind analysis by researchers at the Univ. of Colorado Boulder. Fracking fluid is largely comprised of water and sand, but oil and gas companies also add a variety of other chemicals, including surfactants.
Demand for mass spectrometry continues to rise. According to a recent Marketsandmarkets report, the global mass spectrometry market is expected to reach $5.9 billion by 2018. That’s a healthy compounded annual growth rate of 8.7%. Since its earliest demonstration more than 100 years ago, this analytical technique has become known as the “gold standard” of chemical analysis.
A diet rich in fruit and vegetables is linked to a variety of improved health outcomes, but accurately measuring consumption by self-report, especially with children, is challenging and can be of questionable validity. But a device being developed in a collaboration that involves researchers from the Yale School of Public Health has the potential to change that.
Given today’s widespread use of Raman spectroscopy, it can be hard to believe Raman was a highly specialized analytical technique for most of its history. The technique’s potential was recognized from the beginning: When Raman scattering was first observed in 1928, it was widely believed to be one of the most important scientific discoveries of the 20th century to date.
Rice Univ. researchers have delivered a scientific one-two punch with a pair of papers that detail how synthetic collagen fibers self-assemble via their sticky ends. Collagen is the most common protein in mammals, a major component of bone and the fibrous tissues that support cells and hold organs together. Discovering its secrets may lead to better synthetic collagen for tissue engineering and cosmetic and reconstructive medicine.
As a laboratory technician or director, knowing the current status of your instrument or sample runs is critical for your laboratory’s operations and productivity. Through the rapid increase in machine-to-machine connectivity, real-time instrument monitoring services designed to offer visibility and remote control of these instruments has become an enabler in cost savings, efficiency gains, revenue opportunities and competitive advantage.
Measuring oil content in wastes is nothing new to the petrochemical industry. Whether it’s produced water from onshore or offshore sites, effluents from refineriers or drill cuttings and drilling mud, limits on hydrocarbon levels need to be met. With the increase of hydraulic fracturing in the U.S., more public attention has been focused on the need for regulations and limits.
Spectral sensing is so pervasive that most take it for granted. Even miniature spectrometers have been embraced by late adopters. Yet, spectroscopy has moved beyond routine laboratory and test measurements to take on ever-more sophisticated applications. In this article we explore how familiar spectral sensing technologies—and new ways to exploit them—are today addressing a wider range of measurement problems than ever.
Scientists have been laboring to detect cancer and a host of other diseases in people using promising new biomarkers called “exosomes.” Indeed, Popular Science magazine named exosome-based cancer diagnostics one of the 20 breakthroughs that will shape the world this year. Exosomes could lead to less invasive, earlier detection of cancer, and sharply boost patients’ odds of survival.
The majority of wines are produced from around 20 different types of grape, all of which have their own typical aroma. This is due to the terpenes, a diverse category of chemical substances including cholesterol and estrogen. Scientists have now identified two enzymes that determine the terpene content, and thus the aroma intensity, of grapes. The findings could play an important role in the future development of grape varieties.
The National Institutes of Health this week announced its first research grants through President Barack Obama’s BRAIN Initiative, including three awards to the Univ. of California, Berkeley, totaling nearly $7.2 million over three years. The projects are among 58 funded in this initial wave of NIH grants, involving 100 researchers and a total of $46 million in fiscal year 2014 dollars alone.
