- Abstract:
- ... Drop shape analysis (DSA) techniques measure interfacial tension subject to error in image analysis and the optical system. While considerable efforts have been made to minimize image analysis errors, very little work has treated optical errors. There are two main sources of error when considering the optical system: the angle of misalignment and the choice of focal plane. Due to the convoluted na ...

- Abstract:
- ... Diallyl disulfide (DAD), propyl disulfide (PPD) and dibenzyl disulfide (DBD) flavouring agents as copper corrosion inhibitors in 0.5 mol/L H₂SO₄ solution were evaluated with multitudinous experiments including electrochemical techniques, morphological characterization measurements, FTIR spectra and theoretical calculations. The electrochemical results indicate that PPD and DBD show mixed-type inhi ...

- Abstract:
- ... High-efficiency removal of chloramphenicol (CAP) drug from waste water still faces a large challenge up to date. Herein, we report the first metal-organic framework-based adsorbent (PCN-222) for CAP and effective removal was achieved. PCN-222 exhibits a large adsorption capacity of 370 mg g⁻¹, superior to some other MOFs and various reported adsorbents; and more importantly, the adsorption equilib ...

Ordered mesoporous molybdate-zirconium oxophosphate (M-ZrPMo) solid acid catalysts with controllable molybdenum contents (0–20%) are designed and synthesized through a one-pot evaporation-induced self-assembly strategy. Afterwards, ordered mesostructure and molybdenum species in the materials are systematically researched by a variety of means. The results show that M-ZrPMo has highly ordered meso ...

- Abstract:
- ... The design of surfactants for CO₂/oil emulsions has been elusive given the low CO₂-oil interfacial tension, and consequently, low driving force for surfactant adsorption. Our hypothesis is that waterless, high pressure CO₂/oil emulsions can be stabilized by hydrophobic comb polymer surfactants that adsorb at the interface and sterically stabilize the CO₂ droplets. The emulsions were formed by mixi ...
