In a breakthrough for nanotechnology, engineers at The University of Texas at Austin have developed the first method for selecting and switching the mechanical motion of nanomotors among multiple modes with simple visible light as the stimulus.
In research that may help bridge the divide between the nano and the macro, Brown University chemists have used pyramid-shaped nanoparticles to create what might be the most complex macroscale superstructure ever assembled.
Engineers have observed how carbon dioxide is activated at the electrode-electrolyte interface. Their finding shifts the catalyst design from trial-and-error paradigm to a rational approach and could lead to alternative, cheaper, and safer renewable energy storage.
As an alternative to using lithium in batteries, Purdue University researchers made a sodium powder to prevent sodium-ions from “getting lost” during the first few times a battery charges and discharges.
Researchers have designed a dopant-free hole-transport material based on an alternating copolymer, dithiophene–benzene, which can be easily synthesized in only two steps. Their work features an edge-on orientation, where π–π stacking occurs parallel to the perovskite layer.
Researchers have now used short-term, readily available characterization techniques to develop a simple power law model for predicting calendar aging, obviating the need for long-term experiments.
A new type of battery could be made partly from carbon dioxide captured from power plants. Rather than attempting to convert carbon dioxide to specialized chemicals using metal catalysts, this battery could continuously convert carbon dioxide into a solid mineral carbonate as it discharges.
As demand for heavily-processed natural graphite (for electric vehicle batteries and other applications) continues to drive the graphite market, industry members outside China list greater environmental awareness among the most important changes needed to move the market forward.
Several Japanese automakers jointly announced plans to launch an electric vehicle battery collection and recycling project. The project’s purpose is to establish an efficient and sustainable battery recycling system.
A research group in Japan has developed a machine learning method to analyze complex spectra in materials science. The team used theoretical calculations to construct a spectral database in which each spectrum had a one-to-one correspondence with its atomic structure, where all spectra contained the same parameters.
A research team has developed a fluorescent organic glass with well-defined features that are easily synthesized and processed. Its properties include high thermal stability and low glass transition temperature; and rheological properties that allow for molding, blowing, and nanopatterning.
