New research suggests a one-two punch could help battle polio in some of the world's most remote and strife-torn regions: Giving a single vaccine shot to children who've already swallowed drops of an oral polio vaccine greatly boosted their immunity. The World Health Organization officials said the combination strategy already is starting to be used in mass vaccination campaigns in some hard-hit areas.
Isolators are used to block back-reflected light in a fiber laser. Conventional free-space fiber pigtailed isolators can only handle less than 1 W of back-reflected light, which accounts for the main cause of failure for most fiber laser systems. Estimates are that more than 60,000 fiber lasers are at risk of this type of failure, costing operators $75 million a year. With its All-Fiber Isolator, AdValue Photonics Inc. can now provide fiber laser system operators with the ability to handle more than 200 W of back-reflected light.
Physicians and scientists have two major options when it comes to solid-state lighting for applications in fiber optics: conventional lamps, using xenon gas, or LEDs. The lamps, which may be used for tasks ranging from endoscopy in medical settings or borescopy for jet engine inspection, must supply a high level of consistent, high-quality light. Until recently, LEDs couldn’t generate enough high-quality lumens to compete with xenon lamps. But OSRAM GmbH and Osram Sylvania have jointly developed a new white-light LED module based on laser technology.
Micro GC technology is a proven technology for gas analysis in laboratory, pilot plant and field applications. The principle benefit of Micro GC over a traditional benchtop gas chromatography (GC) is speed of analysis. INFICON’s temperature-programmable Micro GC Fusion has further improved the Micro GC speed advantage, cutting the average analysis time over an isothermal Micro GC in half.
With the capacity to test over 30 of the most critical water-quality parameters across multiple industries through a four-step process, Industrial Test Systems’ eXact iDip is the first water testing photometer that provides seamless data transmission and live syncing of test results using Bluetooth at an affordable price.
Mettler Toledo’s XPE205 analytical balance provides unique performance in analytical weighing and support for the highest requirements for safety, efficiency and ease of compliance. These balances feature two quality management features, the StatusLight and StaticDetect, which take the worry out of weighing and provide users with a high level of trust in their results.
Filling major gaps in field testing for explosives and narcotics, Lawrence Livermore National Laboratory’s microTLC is a miniaturized, field-portable thin layer chromatography (TLC) kit used to detect and identify unknowns. Originally developed to identify military explosives, the device has been modified to also identify and determine the purity of illicit drugs, pesticides and other compounds.
EMD Millipore’s Clarisolve depth filters are specifically tuned to the particle size distribution of various pretreatment methodologies enabling a fast and efficient way to clarify high-density streams and easily transfer processes from upstream to downstream without the use of centrifugation.
Waters Corp. has designed CORTECS 1.6 µm Columns to pair seamlessly with UPLC system technology to deliver the highest performance yet for reversed-phase and HILIC separations. CORTECS features a new, patent-pending charged surface modification that improves the peak shape and loading capacity of basic analytes when run in low-ionic strength acidic mobile phases, such as 0.1% formic acid.
Peptide and protein therapeutics are important drug candidates due to their ubiquitous nature as biological molecules, as well as their ability to control all aspects of cellular function along with many facets of intercellular communication. CEM Corp.’s Liberty Blue automated microwave peptide synthesizer will streamline the peptide synthesis process for pharmaceutical, biotech and academic researchers, enabling them to produce peptides for drug discovery and studies in the field of life sciences in a manner that is more efficient, cost effective, faster and better for the environment.
A team of researchers at Louisiana Tech Univ. has developed an innovative method for using affordable, consumer-grade 3-D printers and materials to fabricate custom medical implants that can contain antibacterial and chemotherapeutic compounds for targeted drug delivery.
It’s official. Yale Univ. physicists have chilled the world’s coolest molecules. The tiny titans in question are bits of strontium monofluoride, dropped to 2.5 thousandths of a degree above absolute zero through a laser cooling and isolating process called magneto-optical trapping. They are the coldest molecules ever achieved through direct cooling, and they represent a physics milestone.
Printing whole new organs for transplants sounds like something out of a sci-fi movie, but the real-life budding technology could one day make actual kidneys, livers, hearts and other organs for patients who desperately need them. In Langmuir, scientists are reporting new understanding about the dynamics of 3-D bioprinting that takes them a step closer to realizing their goal of making working tissues and organs on-demand.
Many laboratories analyzing monoclonal antibodies (mAb) regularly encounter situations where they need alternative hydrophobic interaction chromatography (HIC) selectivity. Thermo Fisher Scientific has developed new column chemistry that separates many more of these challenging mAbs, antibody-drug conjugates (ADCs) and proteins.
Shimadzu Scientific Instruments has introduced two new integrated liquid chromatography systems, Prominence-i and Nexera-i. The i-Series systems are integrated with LabSolutions software. The data acquired by the Prominence-i and Nexera-i via interactive communication mode is sent to a laboratory’s data center by the LabSolutions network and managed uniformly by a server.
