The new Purair 5 Ductless Fume Hoods from Air Science USA feature a high level of operator protection where routine work is being carried out. The units exceed OSHA, ANSI and all relevant international standards.
Researchers in Finland have succeeded in creating a surface on nano-sized cellulose crystals that imitates a biological structure. The surface adsorbs viruses and disables them, preventing their spread into cells. The results could prove useful in the development of antiviral ointments and surfaces.
A 32-year study of subarctic forest moths in Finnish Lapland suggests that scientists may be underestimating the impacts of climate change on animals and plants because much of the harm is hidden from view. The study analyzed populations of 80 moth species and found that 90% of them were either stable or increasing throughout the study period, from 1978 to 2009.
Since the discovery of the Antarctic ozone hole, scientists, policymakers and the public have wondered whether we might someday see a similarly extreme depletion of ozone over the Arctic. But a new Massachusetts Institute of Technology study finds some cause for optimism: Ozone levels in the Arctic haven’t yet sunk to the extreme lows seen in Antarctica, because international efforts to limit ozone-depleting chemicals have been successful.
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.
Researchers in California have created, for the first time, compounds made from mixtures of calcium hexaboride, strontium and barium hexaboride. They also demonstrated that these ceramic materials could be manufactured using a simple, low-cost manufacturing method known as combustion synthesis.
When considering potential drug delivery vehicles, liposomes are an important option and have already been approved for use with a number of therapeutic formulations. Liposomes are comprised of phospholipids and may be single- or multi-layered, can be produced in different sizes and have a hydrophilic interior and hydrophobic shell. They are biodegradable, non-toxic and capable of encapsulating both hydrophilic and hydrophobic materials.
Following an upgrade of the Continuous Electron Beam Accelerator Facility at the Thomas Jefferson National Accelerator Facility, the accelerator delivered the highest-energy electron beams it has ever produced into a target, recording the first data of the 12 GeV era. The machine sent electrons around the racetrack three times, resulting in 6.11 GeV electrons at 2 nanoAmps average current for more than an hour.
Nanotechnology has unlocked new pathways for targeted drug delivery, including the use of nanocarriers that can transport cargoes of small-molecule therapeutics to specific locations in the body. Researchers have recently demonstrated that processing can have significant influence on the size of nanocarriers for targeted drug delivery. It was previously assumed that once a nanocarrier is created, it maintains its size and shape anywhere.
Thirty years have passed since 3-D printers first appeared, but only recently have they hinted at a new era of manufacturing. The first working 3-D printer was created in 1984 by Chuck Hull of 3D Systems Corp. This early device, based on stereolithography, gave way to the first truly practical 3-D printing, or “3DP”, technology patented by the Massachusetts Institute of Technology in 1993.
The R&D 100 Awards is our most prestigious Awards event of the year, and after 52 years of doing this, R&D’s editors believe it’s one of the best ways to gauge the competitiveness of new, technologically-advanced products. But completing our entry process doesn’t have to be difficult. First-time competitors and veteran product development both can benefit from a few helpful tips the editors have put together.
Few areas of instrumentation have prompted as much development or efforts toward innovation as spectroscopy. Without sophisticated approaches to handling light, spectrometers as we know them would not function, and we would be without a deep understanding of the chemical nature of the world around us.
Driven by rapid growth in forensics, biotechnology, disease diagnostics and environmental regulations, chromatography systems have become a laboratory staple. Used for the separation of complex mixtures, detection of illicit drugs and the production of pharmaceuticals, the biotechnology and pharmaceutical industries are the prime users of chromatography techniques.
