About one third of all medicine binds to the same type of receptor in the human body. An estimated 3 percent of the population have receptors of this type that are so genetically different that they are predisposed to altered, ineffective or adverse responses to medicine, a new study from the University of Copenhagen and the MRC Laboratory of Molecular Biology in Cambridge shows.
A team from Ural Federal University (UrFU) developed a new efficient technology of electrical power generation from bituminous coal. The results of the study were published in International Journal of Hydrogen Energy.
A collaboration of scientists has succeeded in verifying a basic prediction of the quantum-mechanical behavior of resonant systems. In the study published in Nature Physics, they were able to carefully follow, one x-ray at a time, the decay of nuclei in a perfect crystal after excitation with a flash of x-rays. They observed a dramatic reduction of the time taken to emit the first x-ray as the number of x-rays increased.
A physicist from Siberian Federal University (SFU) and Kirensky Institute of Physics Federal Research Center KSC SB RAS (IF) described the structure and properties of a new substance obtained by his Chinese colleagues. These are layered crystals of rare earth metal hydroxides Ln2(OH)4SO4 (Ln=Eu-Lu, Y) that may acts as eco-friendly sources of phosphors (substances that transform different energies into emission of light) for panels, screens, and other electronic devices. The discovery was reported by Chemistry: A European Journal.
Chemical engineering professor Daniel Esposito has developed a novel photovoltaic-powered electrolysis device that can operate as a stand-alone platform that floats on open water. His floating PV-electrolyzer can be thought of as a 'solar fuels rig' that bears some resemblance to deep-sea oil rigs -- but it would produce hydrogen fuel from sunlight and water instead of extracting petroleum from beneath the sea floor.
Carbon capture could help coal plants reduce emissions if economic challenges can be overcome. Turning captured carbon into a useable product is one solution. Scientists have developed an efficient process for turning captured carbon dioxide into syngas that can be used to make fuels and chemicals. Results were published Dec. 14 by Green Chemistry. "For the first time it was demonstrated that syngas can be directly produced from captured CO2," the researchers wrote.
An antibiotic candidate compound shelved in the 1970s in favour of more worthwhile drugs could be worth a second look, new research has found.
Scientists of the Friedrich Schiller University Jena, Germany succeeded in developing an efficient method to treat mucoviscidosis. Crucial are nanoparticles that transport the antibiotics more efficiently to their destination. First of all, the active particles need to have a certain size to be able to reach the deeper airways and not to bounce off somewhere else before. Ultimately, they have to penetrate the thick layer of mucus on the airways as well as the lower layers of the bacteria biofilm.
Research teams all over the world are exploring different ways to design a working computing chip that can integrate quantum interactions. Now, Australian and Dutch engineers believe they have cracked the problem, reimagining the silicon microprocessors we know to create a complete design for a quantum computer chip that can be manufactured using mostly standard industry processes and components.
Researchers at University of Tokyo's Institute of Industrial Science report the first direct observation of atoms moving in liquid by collaborating with National Institute of Materials Science. Using scanning transmission electron microscopy, they find that gold ions diffuse through ionic liquid by a phenomenon they describe as a 'cage-jump.' Image analysis determined the diffusion coefficient and activation energy of the diffusion. Quantification of liquid at the atomic level is expected to contribute to the design of energy efficient devices.
