As rapidly developing Asian countries become major players in materials research, they have the perfect opportunity to use new technologies to build a greener energy infrastructure.
Conducting scientific research in Korea has not always been easy. The country has made rapid progress in encouraging research, but how did it come to be able to hold its own on the world stage, and what could the future hold?
Research in India has changed dramatically over the past half century, and C. N. R. Rao has been an observer and participant for all this time. With his unique perspective as an advisor to the Indian prime minister, Nature Materials talked to him about directions in Indian chemistry.
The mammalian sense of taste has an exquisite ability to differentiate subtle variations in flavour. An artificial tongue has now been developed with the ability to amplify and sense analytes that before may have gone unnoticed.
Nanoscale phase separation into a perfect two-dimensional chessboard structure is observed in a class of perovskite-based lithium-ion conductors. The periodicity can be controlled by varying the composition, which is an intriguing advance in materials design.
Interfaces between gold nanoparticle films and semiconductor substrates are found to behave like nearly ideal Schottky diodes. Moreover, the detailed electronic structure of the interfaces can be tuned by electrochemical charge-transfer.
Controlled assembly of nanoparticles can increase their utility for a large range of applications. Selectively functionalizing the ends of hydrophilic nanorods with hydrophobic polymers is an elegant way to do this, as solvent composition provides structure control.
