TL;DR: In this article, a 3D-cellular structure of Stearic acid (SA)/fungi-derived carbon (FDC) composite phase change materials (PCM) was fabricated by vacuum impregnation, where three types of FDC as carrier were synthesized by diverse synthetic procedures of carbonization.

TL;DR: An acoustic metasurface design to extend the wave manipulations to both far- and near-fields while reducing the complexity with a simple structure, which consists of an array of deep-subwavelength-spaced slits perforated in a thin plate.

TL;DR: The synthesis of bifunctional catalysts by supporting cationic porphyrin-based polymers on carbon nanotubes (CNTs) using the direct reaction of 5,10,15,20-tetrakis(4-pyridyl)porphyrin zinc(II), di(1H-imidazol-1-yl)methane, and 1,4-bis(bromomethyl)benzene

TL;DR: This work employs a terahertz metamaterial-based biosensor to an oral cancer cell with and without cisplatin, a chemotherapy drug for cancer treatment, and finds a linear relation between cell apoptosis measured by Flow Cytometry and the relative change of resonant frequencies of the meetamaterial measured by THz time-domain spectroscopy.

TL;DR: In this article, a triboelectric nanogenerator with an organic nanocomposite electret thin film was investigated for mechanical energy harvesting, and it was found that the output current increases by 70% and the equivalent surface charge density reaches 85 μC/m2 in comparison to the virgin PTFE film.
