Rice University chemists find a second level of fluorescence in single-walled carbon nanotubes. The phenomenon may be useful in solar energy and optoelectronic applications.
A new paper in Science Advances describes for the first time how minerals come together at the molecular level to form bones and other hard tissues, like teeth and enamel.
Rusted iron pipes can react with residual disinfectants in drinking water distribution systems to produce carcinogenic hexavalent chromium in drinking water, reports a study by engineers at UC Riverside.
With an increasing demand for a more sustainable alternative for high-rise construction, new research from UBC Okanagan, in collaboration with Western University and FPInnovations, points to timber as a sustainable and effective way to make tall, high-density, and renewable buildings.
Researchers at Chalmers University of Technology, Sweden, have found that graphene-based heat pipes can help solve the problems of cooling electronics and power systems used in avionics, data centres, and other power electronics.
Engineers from NUS have devised a method to convert natural gas into a non-explosive solid form known as gas hydrates, which can be easily stored and transported. Using a novel, low-toxicity additive mixture, the conversion can be completed in just 15 minutes - the fastest time ever reported.
Lancaster University researchers studying a crystalline material have discovered it has properties that allow it to capture energy from the sun. The energy can be stored for several months at room temperature, and it can be released on demand in the form of heat. With further development, these kinds of materials could offer exciting potential as a way of capturing solar energy during the summer months, and storing it for use in winter - where less solar energy is available.
cientists at Tokyo Institute of Technology (Tokyo Tech) have designed a novel catalyst for the Suzuki cross-coupling reaction, which is widely used in the synthesis of industrial and pharmaceutical organic chemicals. Their strategy of loading an intermetallic Pd compound onto a support sharing the same element yields a stable and cost-effective catalyst that outperforms commercially available alternatives.
A new bioinspired prototype offers a total package of features unmatched by any hydrogen sensor currently on the market. While commercial hydrogen sensors only work at 150C or higher, the new tech is powered by light instead of heat. And the sensor can detect hydrogen at concentrations from as little as 10 ppm (for medical diagnoses) to 40,000 ppm (the level where the gas becomes potentially explosive).
Nagoya University scientists have furthered understanding of how plants make a common pigment that might have medicinal applications.
