Polymersome Shape Transformation at the Nanoscale

Elucidating the Phase Transformation of Li4Ti5O12 Lithiation at the Nanoscale.

This work provides insight regarding the fundamental lithiation and delithiation mechanism of the popular lithium ion battery anode material, Li4Ti5O12 (LTO). Our results quantify the extent of reaction between Li4Ti5O12 and Li7Ti5O12 at the nanoscale, during the first cycle. Lithium titanate's discharge (lithiation) and charge (delithiation) reactions are notoriously difficult to characterize ...

A nanoscale shape memory oxide.

Stimulus-responsive shape-memory materials have attracted tremendous research interests recently, with much effort focused on improving their mechanical actuation. Driven by the needs of nanoelectromechanical devices, materials with large mechanical strain, particularly at nanoscale level, are therefore desired. Here we report on the discovery of a large shape-memory effect in bismuth ferrite a...

Censored at the Nanoscale

As soon as researchers uncovered microorganisms’ abilities to communicate, efforts began to control the conversation. Among other cellular functions, quorum-sensing is implicated in biofilm formation, a problematic phenomena in a variety of settings such as persistence of infections (Costerton et al., 1999; Rutherford and Bassler, 2012) and biofouling of waterand wastewatertreatment membranes (...

Thermometry at the nanoscale.

Non-invasive precise thermometers working at the nanoscale with high spatial resolution, where the conventional methods are ineffective, have emerged over the last couple of years as a very active field of research. This has been strongly stimulated by the numerous challenging requests arising from nanotechnology and biomedicine. This critical review offers a general overview of recent examples...
