PRINCIPLES OF THE SPLASH CONTROL TECHNIQUE IN DIVING

INTRODUCTION: "Splash control" is a key element of water entry technique in competitive diving. This process starts from the initial contact of a diver's body with the water surface until complete entry of the rest of the body into the water. The purpose of this study was to establish the most effective hand pattern and body posture that can achieve the best “splash control” to minimize water splash

Thermosensitive Nanocables Prepared by Surface-Initiated Atom Transfer Radical Polymerization

Thermosensitive nanocables consisting of Au nanowire cores and poly(N-isopropylacrylamide) sheaths (denoted as Au/PNIPAAm) were synthesized by surface-initiated atom transfer radical polymerization (SI-ATRP). The formation of PNIPAAm sheath was verified by Fourier transform infrared (FTIR) and hydrogen nuclear magnetic resonance (1H NMR) spectroscopy. Transmission electron microscope (TEM) results confirmed the core/shell structure of nanohybrids. The thickness and density of PNIPAAm sheaths can be adjusted by controlling the amount of cross-linker during the polymerization. Signature temperature response was observed from Au/cross-linked-PNIPAAm nanocables. Such smart nanocables show immense potentials as building blocks for novel thermosensitive nanodevices in future
