New Insecticide Class

August 19, 2014 11:05 am | Award Winners

Dow AgroSciences is constantly searching for technological advances for its insecticide products. The company does this by investigating new chemistries that are discovered and rigorously tested using a variety of techniques, such as bioassays.

Faster Gamma Scans

August 19, 2014 11:02 am | Thermo Fisher Scientific | Award Winners

Portable, handheld radioisotope identification instrument (RIID) technology typically uses one of two types of detector material—sodium iodide (NaI(Tl)) or lanthanum bromide (LaBr)—in combination with a multi-channel analyzer to segregate pulses from specific gamma energies, to provide a gamma energy spectrum used to identify a specific radioisotope.

Lithium Harnessed for Neutron Detection

August 19, 2014 11:00 am | Award Winners

Scientists at the Kansas State Univ.’s SMART Laboratory and Saint-Gobain Crystal in Ohio have capitalized on the availability of 6Li (lithium) to produce Lithium Foil Neutron Detectors that offers equivalent or better detection efficiency compared to present-day helium (3He) detectors.

Responding to Crystal Defects

August 19, 2014 10:59 am | Award Winners

Cadmium zinc telluride (CZT) gamma-ray detectors are important new components in spectroscopic imaging systems because they are the first detectors capable of distinguishing natural gamma-ray background and radioactive isotopes without the need for bulky cooling equipment. The technological difficulties of producing perfect crystals, however, have hindered widespread usage. Brookhaven National Laboratory has successfully addressed these challenges with the introduction of the GammaScout.

TOPICS:

Dopant-enhanced Scintillator

August 19, 2014 10:58 am | Award Winners

Scintillators help identify and differentiate fissionable nuclear materials from benign radioactive sources. The quest for improved radiation detection scintillators has a long history dating back to the early 1900s. Sandia National LaboratoriesTriplet-Harvesting Plastic Scintillators (THPS) address limitations by controlling all aspects of the detector response through specially designed light-harvesting dopants.

TOPICS:

Greater Peak Detection for HPLC

August 19, 2014 10:53 am | Award Winners

Excellims Corp.’s IA3100 integrated, compact high-performance ion mobility spectrometry (HPIMS) detector for high-performance liquid chromatography (HPLC) systems provides complete separation and detection of complex mixtures, particularly when adding the IA3100 capabilities to existent LC hardware, and can complement or serve as an replacement for an end user’s present LC detector.

TOPICS:

X-rays Provide Higher Energy Resolution

August 19, 2014 10:52 am | Award Winners

X-ray spectroscopy is widely used to determine the elemental and chemical composition of materials. However, Lawrence Livermore National Laboratory and STAR Cryoelectronics LLC’s Superconducting Tunnel Junction (STJ) X-ray Spectrometer offers more than 10 times higher energy resolution than current x-ray spectrometers based on silicon or germanium semiconductors.

TOPICS:

Transportable Isotope Ratio Measurements

August 19, 2014 10:50 am | Thermo Fisher Scientific | Award Winners

Before the introduction of Thermo Fisher Scientific’s Thermo Scientific Delta Ray Isotope Ratio Infrared Spectrometer, it was all but impossible to obtain accurate, verifiable real-time or high-frequency sampling of carbon dioxide isotope ratio data from samples at their sources in the field.

A Wide Angle on Chemical Sensing

August 19, 2014 10:48 am | Award Winners

MIT Lincoln Laboratory’s Wide-Area Chemical Sensor (WACS) system uses a tuned, broadband laser coupled to a lossless, spectrally discriminating receiver to detect gases at sensitivities as good as typical local detectors, at ranges up to tens of kilometer, while compensating for atmospheric contaminants and instrumental drift.

TOPICS:

Regenerating Suppressor Design

August 19, 2014 10:47 am | Thermo Fisher Scientific | Award Winners

Thermo Fisher Scientific’s Thermo Scientific Dionex ERS 500 Electrolytically Regenerated Suppressor is a significant leap in electrolytic suppressor product design. The Dionex ERS 500 is the first fully regenerated high-capacity membrane suppressor that eliminates traditional gaskets and a need for frequent off-line regeneration.

TOPICS:

A Fixed Sample Platform

August 19, 2014 10:46 am | Agilent Technologies Inc. | Award Winners

Traditional spectrophotometers have a fixed sample platform and detection stage. This arrangement severely restricts the number and types of measurements that can be undertaken without laborious manual adjustments. Agilent Technologies Australia (M) Pty Ltd has introduced the Agilent Cary 7000 Universal Measurement Spectrophotometer (UMS) and Universal Measurement Accessory (UMA) to aid in this matter.

TOPICS:

Probing the Liquid Vacuum Interface

August 19, 2014 10:43 am | Award Winners

Important scientific studies require precise knowledge of the unique properties at the interface between liquids and solids or at the liquid surface itself. Analyzing these properties has proven difficult because many key analytical instruments are vacuum-based. Pacific Northwest National Laboratory has developed SALVI: System for Analysis at the Liquid Vacuum Interface as a solution.

TOPICS:

Faster Aircraft Defect Analysis

August 19, 2014 10:42 am | Award Winners

In an effort to address the apparent shortcomings in modern inspection technology, Los Alamos National Laboratory developed an Acoustic Wavenumber Spectroscopy (AWS) instrument that performs nondestructive inspection more quickly and easily than prior spectroscopy solutions.

U.S. wants cars to talk to each other

August 19, 2014 10:34 am | by Associated Press, Joan Lowy | News | Comments

The Obama administration has said it is taking a first step toward requiring that future cars and light trucks be equipped with technology that enables them to warn each other of potential danger in time to avoid collisions. A research report released by the National Highway Traffic Safety Administration estimates that the technology could eventually prevent 592,000 left-turn and intersection crashes a year, saving 1,083 lives.

500-million-year reset for the immune system

August 19, 2014 10:22 am | News | Comments

Scientists at the Max Planck Institute of Immunobiology and Epigenetics re-activated expression of an ancient gene, which is not normally expressed in the mammalian immune system, and found that the animals developed a fish-like thymus. To the researchers' surprise, while the mammalian thymus is utilized exclusively for T cell maturation, the reset thymus produced not only T cells, but also served as a maturation site for B cells.
