TL;DR: In this paper, the nanoparticles (i.e., SiO2 and Al2O3 nanoparticles) and methanol are combined into SiO 2/methanol and Al 2O3/mETHanol nanofluids to enhance the CO2 absorption rate of the base fluid (Methanol), and absorption experiments are performed in the bubble type absorber system equipped with mass flow controller (MFC), mass flow meter (MFM), and silica gel (which can remove the methanoline vapor existing in the outlet gases).
Abstract: In this study, the nanoparticles (i.e. SiO2 and Al2O3 nanoparticles) and methanol are combined into SiO2/methanol and Al2O3/methanol nanofluids to enhance the CO2 absorption rate of the base fluid (methanol). The absorption experiments are performed in the bubble type absorber system equipped with mass flow controller (MFC), mass flow meter (MFM) and silica gel (which can remove the methanol vapor existing in the outlet gases). The parametric analysis on the effects of the particle species and concentrations on CO2 bubble absorption rate is carried out. The particle concentration ranges from 0.005 to 0.5 vol%. It is found that the CO2 absorption rate is enhanced up to 4.5% at 0.01 vol% of Al2O3/methanol nanofluids at 20 °C, and 5.6% at 0.01 vol% of SiO2/methanol nanofluids at −20 °C, respectively.

TL;DR: In this paper, a four-step method is proposed to prepare the stable oil-in-binary solution (O/S) emulsion, and a polymer (Gum Arabic) is used as a steric stabilizer.

TL;DR: In this article, a nanopore protein biosensor using a copolymer and diffusive flow of the test sample was developed using a concentration gradient between the nanopore and the micropore sides.
Abstract: A nanopore protein biosensor using a copolymer and diffusive flow of the test sample was developed The copolymer coated within the nanopore can capture the antibody, which then captures the antigen Diffusive flow of a test sample can be obtained using a concentration gradient between the nanopore and the micropore sides No applied voltage was used to create the electrokinetic flow of the test liquid The present nanopore protein biosensor showed high sensitivity and detected antigen quantities as low as 015 nM (4 pg/mL)
