The device has a wide frequency coverage and can detect explosives, chemical agents, and biological substances from safe distances.
Researchers at KU Leuven have developed a metal-free chemical reaction to produce fully functional 1,2,3-triazoles, a key compound for pharmaceutical drugs. The new method expands the possibilities for creating complex compounds without relying on harmful heavy metals.
Biologists discovered a new plant species, Piper kelleyi, that is home to an estimated 40-50 insect species, most of which are entirely dependent on the plant for survival. The study highlights the importance of unique plant compounds in driving evolution and biodiversity.
Dartmouth researchers have developed a pH-activated molecular switch that controls the assembly of a commercially available liquid crystal, changing its readout color from purple to green. This technology may help detect harmful gases, pathogens, and explosives.
Researchers from Germany and Slovakia have found that triclosan concentrations in the Elbe river basin exceeded predicted no-effect concentrations by up to a factor of twelve. Triclosan is currently not included in routine monitoring programs, despite being used extensively in personal care products and sportswear.
Research finds that benzene and BTEX emissions remained dissolved in the Gulf of Mexico, posing a potential health risk to cleanup workers. However, other substances released by crude oil could become airborne, threatening worker health if inhaled.
Baylor researchers propose using data from similar chemicals to predict environmental toxicity and develop environmental safety values. This approach could help prioritize chemical testing, reducing the need for unnecessary animal testing while maintaining environmental safety.
Scientists have developed a new material consisting of copper-coated silica nanoparticles that can eliminate unpleasant odors. These nanoparticles are up to twice as effective as the current gold standard, activated carbon, in removing foul-smelling substances like ethyl mercaptan.
Scientists developed a new approach to eliminating unpleasant odors using nanoparticles coated with copper, which are hundreds of times smaller than peach fuzz. These particles show promise for removing sulfur contaminants and harmful bacteria.
Researchers at Florida Institute of Technology have developed a streamlined process for synthesizing the chemical compound CDNI-Glu, reducing production time from 150 hours to 24 hours. The licensed technology will be commercially available through Tocris, enabling neuroscientists to study brain neural networks more efficiently.
Scientists at Carnegie Institution create novel 'compound' from pure boron, exhibiting low mass, high strength, and response to neutron irradiation. The discovery builds on previous superconductivity findings in boron and paves the way for understanding its transition to superconductivity under pressure.
Researchers at Southern Methodist University identified four potent chemical compounds that slow neuron degeneration, a key cause of old-age diseases like Alzheimer's and Parkinson's. The compounds, called 3-substituted indolin-2-one derivatives, are non-toxic even at high doses, offering hope for halting neurodegenerative diseases.
Researchers have found semiconducting nanotubes produced by living bacteria, opening the door to cheaper and more environmentally friendly manufacture of electronic materials. The discovery could lead to novel functionality for next-generation semiconductors in nano- and opto-electronic devices.
A new XML-based architecture could improve access to chemical information in biomedical literature, reducing errors and increasing publication efficiency. The proposed system would link to open databases like PubChem, enabling readers to easily identify compounds mentioned in articles.
Arthur Gossard, a professor at UCSB, has received the James C. McGroddy Prize for his contributions to molecular beam epitaxy, a key technology for compound semiconductors used in wireless and fiber-optic devices. The prize honors his work on device applications and physical understanding of low-dimensional structures.
Researchers have discovered chemical cousins of an antimalarial drug that show promise in treating serious antibiotic-resistant infections. The compounds, originally developed to treat malaria and other parasitic infections, have been found to be as active as many currently used drugs against a range of bacteria, including staphylococc...
Scientists at Ohio University and Russia discovered that carnosine and N-acetyl-carnosine can prevent alcohol's assault on red blood cells, allowing them to maintain their healthy shapes. The findings have implications for the development of a treatment for anemia in alcoholics.
A team of astronomers has discovered a new molecule, nitrogen sulfide, in comets, which may offer insights into the formation of the early solar system. The compound's presence in comets suggests that it could have originated from the material that formed the planets.
Using high-intensity ultrasound, researchers discovered a dramatically improved catalyst for removing sulfur-containing compounds from gasoline and other fossil fuels. The new form of molybdenum disulfide is 10 times more active than the standard industrial catalyst.
New anti-TBT regulations may actually increase environmental and human health risks for countries with limited resources. The regulations result in $4 billion in added fuel costs for the shipping industry.
Seventy percent of ships use TBT-based paints, which pose a constant but low release risk. Researchers are exploring alternative antifouling technologies that can match performance while being environmentally safe.
A new measurement technique developed by researchers at the University of Illinois can identify and measure up to 30 compounds found in a single cell. The method uses nanoliter sampling, capillary electrophoresis, and fluorescence spectroscopy to provide a detailed snapshot of the cell's physiology.
The Harbor Branch Oceanographic Institution has received a three-year, $1.1 million grant to investigate the potential anticancer properties of Discodermolide, a marine-derived compound. The study aims to evaluate the effectiveness of Discodermolide on experimental models of human lung, breast and ovarian cancers.
In a study by Cornell University, male fire-colored beetles (Neopyrochroa flabellata) entice females with a chemical offering containing cantharidin. The female ingests the chemical, which is then transferred to her eggs, protecting them from predators. This unique strategy highlights the resourcefulness of male insects in seeking mates.
