Summary: Zeta potential is a surface characteristic formed on the solid surface and liquid interface, which can be used to describe the surface properties of materials. In this study, four homemade stationary phases containing phosphate groups were investigated based on their surface zeta potential. The majority of cases showed negative zeta potential values, but positive zeta potential was observed in some solvents. It was also found that the type of silica gel used for the stationary phase synthesis did not affect the zeta potential.

Summary: Thermal transport in a non-Newtonian fluid flow through a parallel plate microchannel is studied with a focus on the effects of high zeta potential and steric factor. The flow behavior is modeled using a power law and is driven by a combination of electric field and pressure gradient. The study considers the impacts of joule heating, viscous dissipation, and slip length at the wall. A semi-analytical formulation for the temperature profile is developed and solved numerically. The results show that the Nusselt number increases with the flow behavior index and that velocity slip has a positive impact on convective heat transfer. However, as the zeta potential and steric factor increase, the Nusselt number starts to decrease due to increased viscous dissipation. The study emphasizes the importance of considering variable electrical conductivity in evaluating the effect of joule heating in high zeta potential and moderate steric factor conditions. A comprehensive thermal map is developed for a wide range of zeta potentials and steric factors.

Summary: This study theoretically investigates the electroosmotic and electromagnetohydrodynamic (EMHD) transport of couple stress fluid in a microchannel under simultaneous magnetic and electric field. The flow dynamics, thermal transport, and entropy generation in a thermofluidic system with slip-dependent (SD) zeta potential are predicted. Key parameters such as couple stress, slip length, Hartmann number, pressure gradient, and transverse electric field are considered, and their effects are shown graphically. The results highlight the significant influence of flow velocity and thermal energy distribution on entropy generated in the channel under SD zeta potential.

Summary: The absorption performances of CO2 into AMP solutions mixed with water, EG, DEG, and TEG were investigated and compared in a T-junction microchannel. The results show that solvents affect the absorption rate with the order of AMP-water < AMP-EG < AMP-DEG < AMP-TEG, which is opposite to their solubility. Increased pressure drop and shorter bubble surrounded with thicker film are the dominant factors affecting the absorption rate. Under current conditions, water is a feasible solvent choice.

Summary: This study quantitatively investigated the lateral motion of micro-particles in different microchannels based on the Dean drag force. It was found that in both square and half-circle microchannels, the particles exhibited a twist-type lateral trajectory around each turn, with the larger particles twisting in the opposite direction of the smaller particles. This indicates the potential for particle separation solely due to the Dean drag force. The separation efficiency decreased with decreasing Dean and Reynolds numbers. In cases of symmetric sheath flow, the particles showed minimal lateral deflection and no separation was achieved.

Summary: This paper extends the four-component relativistic Dirac-Kohn-Sham method to include environmental and confinement effects in the frozen density embedding (FDE) scheme. The implementation is facilitated by the BERTHA code's python API (PyBERTHA) and auxiliary density fitting techniques. The accuracy and numerical stability of the implementation are demonstrated on the NH3-H2O system and the computational performance is evaluated on gold clusters and heavy elements. The results show that FDE improves upon current approximations and provides a basis for generating more realistic radial potentials for confined atoms.

Summary: A sufficient amount of ionic surfactants can disperse silica particles in water-glycol mixtures with a zeta potential of around 100 mV. The addition of HCl had little effect on the zeta potential, while excess NaOH induced a zeta potential of about -80 mV in 50% EG and less significant effect in 50% PG. Excess CTMABr induced a zeta potential of about +100 mV in both 50% EG and PG, while excess SDS induced a zeta potential of about -80 mV in both 50% EG and PG.

Summary: The aggregation behavior of low charge density thermoresponsive polyelectrolytes was investigated in organic counterion aqueous solutions. Two thermoresponsive polyelectrolytes, P-NIP-SPAK and P-NIP-AAPTAC, were synthesized. The polyelectrolytes remained soluble in their solutions due to the strong hydration property of the ionic groups. Aggregation occurred when organic counterions were added, attributed to the salting-out effect of counterions near the polyelectrolyte surface. This aggregation behavior was utilized for charge-selective recognition of amino acids.

Summary: In this study, a one-step immunoassay for microdroplets using nanoparticle assembly at the interface by spontaneous emulsification is proposed. It was found that nanoparticles with diameters less than 50 nm were uniformly adsorbed to the microdroplet interface as a Pickering emulsion, whereas larger nanoparticles tended to aggregate in the bulk part of the microdroplet. The feasibility of this method was demonstrated using rabbit IgG as the analyte, and it is expected to be a powerful tool for trace biochemical analyses.

Summary: In this study, a simple enrichment method utilizing water-insoluble organic nanocrystals accumulated on μPAD was developed for sensitive multi-ion detection. By combining the enrichment method with multivariate data analysis, three metal ion concentrations in the ion mixtures were simultaneously quantified with high sensitivity. Zn2+, Cu2+, and Ni2+ were successfully quantified at 20 ng L-1 in the mixed ion solution using only two dye indicators, with a larger sensitivity improvement than previous studies. Interference studies revealed possibilities for practical application in real sample analysis. This developed approach can also be used for other analytes.

Summary: The quasi-elastic laser scattering (QELS) method is an optical scattering measurement technique that utilizes thermally excited capillary waves at gas/liquid and liquid/liquid interfaces. It can optically measure surface tension, which is a distinct characteristic in micro-nano sciences. Unlike conventional QELS methods, the new QELS method utilizes spontaneous capillary wave resonance at spatially restricted interfaces in microchannels, microwells, and microdroplets, eliminating the need for precise scattering angle determination and wavelength information for surface tension calculation.

Summary: This study investigates the relationship between the morphology of PMMA monopolymers and PMMA-PHEMA copolymers with the expected nature of surfactant-free microemulsions (SFMEs) before polymerization. It is found that previously mesostructured, surfactant-free mixtures can produce porous polymers of different morphologies, while unstructured, oil-rich regions lead to solid, transparent polymers without nanostructured morphologies. Additionally, a surfactant-based reference system shows similar phase behavior and polymer morphologies as the comparable surfactant-free system, indicating the importance of the hydrotropic behavior of HEMA in this system.
