Record-breaking number of boron atoms recorded in a single molecular species

Scientists in the United States have synthesised a molecular species containing the highest number of boron atoms ever recorded by crystallographic characterisation.

The unique supramolecular cuboctahedron contains 240 boron atoms. The previous record for the most boron atoms in a single species was a heptanuclear silver aggregate reported in 2010, but this species contained only 88 boron atoms.

Boron-rich nanostructures form the basis of high-energy materials, nanoelectric materials and boron neutron capture therapy agents.

    Using yeast to create alternative petrochemical processes

    As climate change continues to do more damage to our planet, scientists are working to find more efficient and cleaner ways to power the earth. One appealing alternative to common petrochemical processes that generate significant greenhouse gases and other waste products could come from bio ... more

    Engineers create double layer of borophene for first time

    For the first time, Northwestern University engineers have created a double layer of atomically flat borophene, a feat that defies the natural tendency of boron to form non-planar clusters beyond the single-atomic-layer limit. Although known for its promising electronic properties, borophen ... more

    New 'Swiss Army knife' cleans up water pollution

    Phosphate pollution in rivers, lakes and other waterways has reached dangerous levels, causing algae blooms that starve fish and aquatic plants of oxygen. Meanwhile, farmers worldwide are coming to terms with a dwindling reserve of phosphate fertilizers that feed half the world's food suppl ... more

    Light-Powered 3-D Printer Prints Stent

    The 3-D printer in Cheng Sun’s lab allows researchers to fabricate materials that precisely fit their designs. It uses a photo-polymer in liquid form that coverts into a solid when light is applied. The material actually forms to the shape of the projected light, creating a 3-D structure. more

    New coating is self-defence for seeds

    Scientists in Switzerland have developed a protective coating for seeds that poisons pests with cyanide when they bite into it. The coating is a system of two layers and only becomes toxic when the layers are mixed, eliminating the problem of environmental contamination that is associated w ... more

    Using bacteria to make electrodes

    Scientists in France have produced hematite using a bacterial pathway for use as an electrode material in Li-ion technologies. Currently, most commercial electrode materials for Li-ion technologies are prepared using the ceramic method, which requires long heating periods at high temperatur ... more

    Marine plant replacement for platinum in solar cells

    An international research team has shown that that the power conversion efficiency of sea tangle extract is comparable to platinum in solar cell electrodes. Dye-sensitized solar cells (DSCs) are quickly becoming a widespread and affordable alternative to photovoltaic solar cells. The electr ... more
