TL;DR: In this article, the authors demonstrate a simple, low cost and effective approach of using the charging process in friction to convert mechanical energy into electric power for driving small electronics, which is fabricated by stacking two polymer sheets made of materials having distinctly different triboelectric characteristics, with metal films deposited on the top and bottom of the assembled structure.

TL;DR: Shell-isolated nanoparticle-enhanced Raman spectroscopy is reported, in which the Raman signal amplification is provided by gold nanoparticles with an ultrathin silica or alumina shell, which significantly expands the flexibility of SERS for useful applications in the materials and life sciences, as well as for the inspection of food safety, drugs, explosives and environment pollutants.

TL;DR: A new high-output, flexible and transparent nanogenerator by using transparent polymer materials that far surpassed that exhibited by the unstructured films and gave an output voltage of up to 18 V at a current density of ∼0.13 μA/cm(2).

TL;DR: Progress in nanogenerators for mechanical energy harvesting is reviewed, mainly including two key technologies: flexible piezoelectric nanognerators (PENGs) and flexible triboelectrics nanogsenerators (TENGs).

TL;DR: A general rule is preliminarily proposed that the atomic radius, bond dissociation energy, and electronegativity of the core and shell metals play key roles in determining the conformal epitaxial layered growth mode.
