Synthesis of thorium tetrafluoride (ThF4) by ammonium hydrogen difluoride (NH4HF2)
Nuclear Engineering and Technology, 2019 The present study aims to investigate the fluorination of thorium oxide (ThO2) by ammonium hydrogen difluoride (NH4HF2). Fluorination was performed at room temperature by mixing ThO2 and NH4HF2 at different molar ratios, which was then left to react for ...

Electrically Tunable Heliconical Smectic Superstructure in Polar Fluids
Advanced Materials, EarlyView.Strong dipole–dipole interactions give rise to an emergent polar smectic phase with spontaneous chiral symmetry breaking. This resulting polar heliconical smectic superstructure enables novel functionalities in polar fluids, such as color modulation driven by electric field strength and frequency, as well as second‐harmonic generation amplification ...

Controlled Hydrophilic–Hydrophobic Transition of PET Films via Fluorination and Drying
PhyschemPolyethylene terephthalate (PET) films were modified by direct fluorination using fluorine gas at room temperature and 660 torr for reaction times ranging from 10 min to 5 h. Some of the fluorinated samples were dried at 70 °C for 7 days.
