A Trihybrid Approach for Enhancing Crude Oil Recovery Using Effervescent-Tablet-Based Nanofluids.

While nanofluids can contribute enormously to enhanced oil recovery (EOR) in the upstream sector, conventional nanofluids are produced using complex equipment and expertise, which is somewhat limiting. To address this issue, herein, the use of effervescent-tablet-based nanofluids for EOR is reported. Tablets are formed by mixing and consolidating multi-walled carbon nanotubes, surfactants, and effervescent agents.

Deposition of Stainless Steel Thin Films: An Electron Beam Physical Vapour Deposition Approach.

This study demonstrates an electron beam physical vapour deposition approach as an alternative stainless steel thin films fabrication method with controlled layer thickness and uniform particles distribution capability. The films were fabricated at a range of starting electron beam power percentages of 3⁻10%, and thickness of 50⁻150 nm. Surface topography and wettability analysis of the samples were investigated to observe the changes in surface microstructure and the contact angle behaviour of 20 °C to 60 °C deionised waters, of pH 4, pH 7, and pH 9, with the as-prepared surfaces.
