Abstract

Abundant pH and UV light stimuli-responsive behaviors of Gemini surfactant 12-3(OH)-12·2Br− and trans-ortho-hydroxyl cinnamic acid in aqueous solution.

Versatile Pickering Emulsions Stabilized by Polyphenolic 2D Janus Nanosheets Enhance Foliar Deposition of Agrochemicals

“…A similar phenomenon has also been reported in some literature and was deemed reasonable. 41,42 Consequently, the typical shear-thinning behaviors unambiguously manifest that the emulsions are all non-Newtonian fluids, 43 which would facilitate the Pickering emulsion to spread out on the surface of leaves. By contrast, the viscosities of O/W and W/O coexisted emulsions (φ o = 22−70%) are generally higher than those of O/W emulsions (φ o = 5−15%), which probably due to the W/O emulsion droplets are denser and stack with each other, thus quite a few of emulsions still hang out at the bottom of vial against gravity when φ o are 30 and 70% (inset in Figure 4d).…”

Emerging delivery systems based on aqueous two-phase systems: A review

“…Extremely low tension can be achieved in ATPSs by adjusting both solutes’ concentrations 54 . The comparatively softer and broader range of interfacial tension can help to elucidate the interfacial properties of w/w systems, such as the response to external stimuli 55 . Moreover, the low interfacial tension is advantageous for applications that require low-tension w/w systems, such as the interfacial assembly of microparticles or nanoparticles, particularly in specific transport systems with dynamic changes 53 .…”
