Scientists from Trinity College Dublin have taken a giant stride towards solving a riddle that would provide the world with entirely renewable, clean energy from which water would be the only waste product. Reducing humanity’s carbon dioxide (CO2) emissions is arguably the greatest challenge facing 21st-century civilization – especially given […]

High-energy-density polymeric cathode for fast-charge sodium- and multivalent-ion batteries. Next-generation batteries will probably see the replacement of lithium ions by more abundant and environmentally benign alkali metal or multivalent ions. A major challenge, however, is the development of stable electrodes that combine high energy densities with fast charge and discharge […]

Boston College Professor of Earth and Environmental Sciences Ethan Baxter, at work on Greek island of Sifnos. Analysis of garnet samples collected on the island confirmed theories that water flowing from deep in the Earth millions of years ago is the source of oxidation found in the remnants of ancient […]

Credit: Kristina Kvashnina An international team of scientists, led by the Helmholtz Zentrum Dresden-Rossendorf (HZDR), have found a new compound of plutonium with an unexpected, pentavalent oxidation state, using the ESRF, the European Synchrotron, Grenoble, France. This […]

A research team from Tokyo Institute of Technology (Tokyo Tech) and Kanazawa University developed an eco-friendly device that uses solar energy to catalyze an electrochemical oxidation reaction with high efficiency. Green energy sources constitute a hot research field globally because of the current environmental crisis and the necessity to avoid […]

For DNA to be read, replicated or repaired, DNA molecules must open themselves. This happens when the cells use a catalytic protein to create a hydrophobic environment around the molecule. Illustration Credit: Yen Strandqvist/Chalmers University of Technology Researchers at Chalmers University of Technology, Sweden, disprove the prevailing theory of how DNA binds […]

Nature has evolved a dazzling array of materials that help organisms thrive in diverse habitats. Sometimes, scientists can exploit these designs to develop useful materials with similar or completely new functions. Now, researchers reporting in ACS Applied Materials & Interfaces have made a durable and flexible super-water-repelling material inspired by spiky porcupinefish […]
