To improve the photothermal conversion capability of PCMs, we developed composite phase change materials (FHS@PCMs) of sea urchin-like Fe 3 O 4 hollow spheres (FHS) loaded with fatty amines (hexadecylamine (HDA) and octadecylamine (ODA)). The material composition and the surface nano-raised ...

During the calcination process, sea-urchin like morphology was obtained with nickel nanoparticles as the core and nitrogen-doped carbon nanotubes (NCNTs) as the shell. The optimized Ni@NCNTs-1.5 material exhibits a high H2O2 selectivity of >90 % in a wide potential range of 0.2–0.6 V, and...
Sensitivity and pressure range are two significant parameters of pressure sensors. Existing pressure sensors have difficulty achieving both high sensitivity and a wide pressure range. Therefore, we propose a new pressure sensor with a ternary nanocomposite Fe2O3/C@SnO2. The sea urchin-like Fe2O3st...
Sea urchin-like Ag–α-Fe2O3 nanocomposite microspheres are developed for gas sensing applications. Such hierarchical nanostructures were synthesized by a two step approach including a hydrothermal reaction and a subsequent incipient wetness impregnation process. The large Brunauer–Emmett–Teller (BET)...
Ag-coated sea-urchin-like Fe3O4@C core-shell particles can be synthesized by a facile one-step solvothermal method, followed by deposition of high-density Ag nanoparticles onto the carbon surface through an in situ growth process, respectively. The as-synthesized Ag-coated Fe3O4@C particles ...
We present novel sea-urchin-like ZnO nanoparticles synthesized using a chemical solution method. Solution approaches to synthesizing ZnO nanostructures have several advantages including low growth temperatures and high potential for scaling up. We investigated the influence of reaction times on the thickness...
Analysis of pressure-sensing mechanism of sea urchin-like PS/PPANI composite microsphere-based flexible pressure sensor Fig. 1(a) shows the sensing mechanism between urchin-like PS/PANI composite microspheres in the pressure sensitive layer of the pressure sensor. Essentially, the working mechanism of...
