Nanomaterials design beyond the limit of geometrical symmetry

Mon, 09/17/2018 - 16:02
Scientists have theoretically demonstrated that special tetrahedron nanostructures composed of certain metals have a higher degree of symmetry than the geometrical symmetry of spherical atoms. Nanomaterials with unique and unprecedented electrical and magnetic properties arising from this symmetry will be developed and used for next-generation electronic devices.

2D material produces highest ever signals for human embryonic stem cell detection

Mon, 09/17/2018 - 09:37
Researchers have developed a way to achieve an ultra-high bioelectric signal from human embryonic stem cells using direct current-voltage measurements facilitated by few-layered 2D molybdenum disulfide sheets. This method, which produces cell signals 2 orders of magnitude higher than previous electrical-based detection methods, paves the way for the development of a broadly applicable, fast, and damage-free stem cell detection method capable of identifying pluripotency with virtually any complementary metal-oxide-semiconductor circuits.

The rise of phosphorene analogue optoelectronic materials

Thu, 09/13/2018 - 09:39
Black phosphorus (BP or phosphorene), a novel two-dimensional semiconducting material, has gained tremendous attention because of its intriguing properties, such as ON/OFF ratio, high carrier mobility, and tunable direct band. However, a fundamental obstacle hindering practical applications is the lack of stability under ambient conditions. Now researchers demonstrated both excellent photoelectrochemical performance and significantly improved stability based on tin monosulfide nanosheets. These findings hold great potential for practical applications of phosphorene analogue nanomaterials-based devices.
