  • Eco-pottery product from water treatment sludge
    Sludge obtained from water treatment plants were studied as suitable materials to be used in the pottery industry to make suitable pottery products.

  • Spinach could lead to alternative energy more powerful than Popeye
    Spinach gave Popeye super strength, but it also holds the promise of a different power for a group of scientists: the ability to convert sunlight into a clean, efficient alternative fuel. Physicists are using spinach to study the proteins involved in photosynthesis, the process by which plants convert the sun's energy into carbohydrates used to power cellular processes. Artificial photosynthesis could allow for the conversion of solar energy into renewable, environmentally friendly hydrogen-based fuels.

  • Electronic nose could aid in rescue missions
    Researchers have developed a device that allows multiple robotic platforms to follow the path of certain odors. A technology which could aid the search and rescue of people in case of natural disasters such as earthquakes, hurricanes or floods.

  • First total synthesis of madangamine D, a molecule of biomedical interest
    Madangamines are a group of polycyclic alkaloids from marine sponges which have biomedical interest due to their cytotoxic activity. Chemists have now completed the first total synthesis of madangamine D, a scientific discovery in the field of organic chemistry.

  • Chemists eye improved thin films with metal substitution
    The yield so far is small, but chemists have developed a low-energy, solution-based mineral substitution process to make a precursor to transparent thin films that could find use in electronics and alternative energy devices.

  • More than glitter: How gold nanoparticles easily penetrate cells, making them useful for delivering drugs
    A special class of tiny gold particles can easily slip through cell membranes, making them good candidates to deliver drugs directly to target cells. Scientists can now explain how gold nanoparticles easily penetrate cells, making them useful for delivering drugs.

  • Replacing coal, oil with natural gas will not help fight global warming, expert argues
    Both shale gas and conventional natural gas have a larger greenhouse gas footprint than do coal or oil, especially for the primary uses of residential and commercial heating. "While emissions of carbon dioxide are less from natural gas than from coal and oil, methane emissions are far greater. Methane is such a potent greenhouse gas that these emissions make natural gas a dangerous fuel from the standpoint of global warming over the next several decades," said the author of a new article.

  • Tiny laser sensor heightens bomb detection sensitivity
    Researchers have created a plasmon laser detector that can sniff out tiny traces of airborne molecules of explosives. The sensor detected both DNT and ammonium nitrate at concentrations below one part per billion.

  • A noble gas cage: New material traps gases from nuclear fuel better and uses less energy than currently available options
    A new material called CC3 effectively traps xenon, krypton, and radon. These gases are used in industries such as lighting or medicine and, in the case of radon, one that can be hazardous when it accumulates in buildings. New research shows how: by breathing enough to let the gases in but not out. The results might lead to cheaper, less energy intensive ways to extract these gases.

  • Cheap, highly efficient solar cells: A new stable and cost-cutting type of perovskite solar cell
    Scientists have made a very efficient perovskite solar cell that does not require a hole-conducting layer. The novel photovoltaic achieved energy conversion efficiency of 12.8 percent and was stable for over 1000 hours under full sunlight. The innovation is expected to significantly reduce the cost of these promising solar cells.
