The high demand on fast rechargeable batteries and supercapacitors combined with the limited resources of their active materials (e.g. Li Co) motivate exploration sustainable energy storage systems such as Zn-ion hybrid supercapacitors. MXenes are two-dimensional outstanding properties conductivity capacitance which enhance performance in devices. Herein, we report use freestanding Mo1.33CTz–Ti...

Information Storage In article number 2213668, Ming Liu, Bin Peng, and co-workers introduce a self-assembly method to fabricate scroll-like 3D architecture, which can increase the information storage density in ferroelectric memories. It is enabled by self-rolling-up of freestanding single-crystalline ferroic oxide membranes. The could be enhanced at least one order magnitude (experimentally 45...

As a remarkable orientationally ordered soft-condensed matter system, the smectic-C*(alpha) phase exhibits an incommensurate nanoscale helical pitch of more than four smectic layers. Recent theoretical advances predict the existence of a new phase showing a helical pitch of less than four smectic layers (<16 nm). By applying a novel optical technique to the study of freestanding films with incr...

Differential optical reflectivity (DOR) was used to study the temperature dependence of the short helical pitch in freestanding films of a liquid crystal compound. The experimentally measured DOR signal was fitted using Berreman's 4 x 4 matrix method to get the pitch value in the smectic-C*alpha (sMC*alpha) phase. The results show continuous evolution of the pitch between the smectic-C*alpha an...

A MEMS sensor has been developed for use as a calorimetric cell in an ultra-sensitive, thin-film, differential scanning calorimetric technique. The sensor contains a freestanding, thin (30 nm to 1000 nm), low-stress silicon nitride membrane with lateral dimensions of a few millimeters. This membrane, along with a thin (50 nm) metallization layer, forms a calorimetric cell with an exceptionally ...
