TL;DR: It is demonstrated that the nanostructures comprising silver cores and dense layers of Y(2)O(3):Er separated by a silica shell are an excellent model system to study the interaction between upconversion materials and metals in nanoscale.

TL;DR: In this paper, size-controlled and coated magnetite nanoparticles with glucose and gluconic acid have been successfully synthesized via a simple and facile hydrothermal reduction route using a single iron precursor, FeCl3, and a combination of the inherent chemical reduction capability of sucrose decomposition products and their inorganic coordinating ability.

TL;DR: A comprehensive review of the relationship between Coulombic efficiency (ICE) and energy density can be found in this paper, where a detailed assessment of the reasons of the initial capacity loss (low ICE) for various types of anode materials.

TL;DR: In this paper, a honeycomb-like, nitrogen-rich, hierarchically porous, and highly disordered carbonaceous material (N-HC) with an expanded interlayer distance (0.44 nm in average) is synthesized by spray drying and subsequent pyrolysis under flowing NH3.

TL;DR: The hollow and porous structure of dandelion-like ZnO spheres facilitated the diffusion of gas molecules, leading to a rapid response speed and good selectivity of hierarchical ZNO spheres gas sensor at low operating temperature.
