Abstract In this study, super-amphiphobic nano-silica nanoparticles (SA-NPs) were used to enhance the shale stabilization performance of water-based drilling fluids (WBDFs) by altering surface wettability, preventing capillary self-priming effect, and plugging nano-micro pores shale. The results transmission electron microscopy, particle size distribution, scanning microscopy characterization r...

The polymer polyvinylidene difluoride (PVDF) has unique piezoelectric properties favorable for Micro-Electro-Mechanical Systems (MEMS) and Nano-Electro-Mechanical Systems (NEMS) applications. In the present research, we conducted nanometer-length scale characterization of this material using several high-resolution techniques. Specifically, we used an atomic force microscope (AFM) to study the ...

wood is a naturally renewable material with both continuous and isolated pore systems. wood-composite panels have the privilege of offering a homogeneous structure to be used as constructional and structural materials. however, its nature makes it susceptible to biological wood-deteriorating agents, water absorption and thickness swelling, fire, etc. using nano-materials are very easy in the wo...

Recent advances in computational materials science present novel opportunities for structure discovery and optimization, including uncovering of unsuspected compounds and metastable structures, electronic structure, surface, and nano-particle properties. The practical realization of these opportunities requires systematic generation and classification of the relevant computational data by high-...
