A single process for how a group of molecules called nucleotides were made on the early Earth, before life began, has been suggested by a UCL-led team of researchers.
A Florida State chemistry professor created a plutonium compound that behaves much more like lighter elements, giving scientists new information about how this element works.
Better medical responses to the accidental or intentional release of inhaled toxic chemicals are being developed, but the field faces considerable challenges, according to a new report by an international panel of experts. The report, 'Chemical Inhalation Disasters: Biology of Lung Injury, Development of Novel Therapeutics, and Medical Preparedness,' has been published online in the Annals of the American Thoracic Society.
Northeastern researchers Yung Joon Jung and Swastik Kar have developed a way to detect nuclear materials that far outpaces any existing method.
Pre-lithiated multiwalled carbon nanotubes and activated carbon (AC) materials were used as anode and cathode respectively for Lithium-ion capacitors (LICs). The pre-lithiatiation was performed using internal short circuit approach (ISC). The LIC showed excellent supercapacitor performance. The pre-lithiated MWCNTs have a potential application as anode for high performance Lithium-ion capacitors.
Chemists at the University of Texas at Austin have developed a material that holds the key to cheap, fast and portable new sensors for a wide range of chemicals that right now cost government and industries large sums to detect.
There's a reason why farmers wear protective gear when applying organophosphate pesticides. The substances are very effective at getting rid of unwanted bugs, but they can also make people sick. Related compounds -- organophosphate nerve agents -- can be used as deadly weapons. Now researchers have developed a fast way to detect the presence of such compounds in the field using a disposable 'lab-on-a-glove.' The report on the glove appears in the journal ACS Sensors.
Chemists from Russia and Switzerland created biosafe luminescent nanoparticles for imaging tumors and blood vessels damaged by heart attack or stroke. The particles are made of hafnium oxide that is allowed for intravenous injection, and doped with ions of rare earth metals. The scientists hope that the development will give an alternative to toxic quantum dots and help imaging deep tissues without harming a human body. The study appeared in Colloids and Surfaces B: Biointerfaces.
A synthetic ion channel provides different-shaped paths into a cell. This could offer insight into how these unique channels function in living organisms.
A Washington State University study of the chemistry of technetium-99 has improved understanding of the challenging nuclear waste and could lead to better cleanup methods.
