(Phys.org)—Colloidal systems are important in nanoscience and materials. A colloidal system involves the dispersion of particles within a solvent. A stable colloid has evenly dispersed solute particles while unstable colloids ...
(Phys.org)—The pentazole molecule and its anion, cyclo-N5- has proven elusive to researchers for almost a century. The pentazole anion is highly unstable and cannot be made in bulk. Researchers from Nanjing University of ...
Proponents of clean energy will soon have a new source to add to their existing array of solar, wind, and hydropower: osmotic power. Or more specifically, energy generated by a natural phenomenon occurring when fresh water ...
