Summary: The generation of fiber foams with surface aeration was studied by simultaneously mixing pulp fibers, surfactant, air, and water in a lab-scale tank under transient or turbulent conditions. The air content and bubble size were found to be influenced by mixing power and surfactant dosage, with the half-life time of the foam related to air content. The impeller type and mixing Reynolds number were identified as factors affecting the power number during mixing.

Summary: The study presented an experimental setup for in-situ characterization of physical parameters of food foams, showing reliable determination of yield stress, gas volume fraction, and bubble size distribution at different heights. It was found that the gas volume fraction and bubble size increase monotonically during free drainage, and gradients of structural and rheological parameters along the direction of gravity increase over time. The yield stresses in milk foams were as predicted from phenomenological modeling, emphasizing the reliability of the measurement setup.

Summary: This study investigates the influence of interstitial slurry rheology on the pore structure of chemically foamed geopolymer foams (GPFs). Different metakaolin/fly ash ratios were used to achieve a range of slurry rheological properties, and a high-foam-content system was created using a H2O2 solution. The study tests the slurry rheological properties, foaming properties, and pore structures of the GPFs to understand the effect of rheology on bubble behavior and pore structures. Equations describing the relationship between bubble pressure, extrusion pressure, and slurry yield stress are discussed, and four sequential phases of bubble deformation during the foaming process are identified. The findings of this study provide essential guidance for designing and synthesizing porous cementitious materials.

Summary: Aqueous foams have a wide range of applications and play an important role in various industries. In this study, we explore the spontaneous generation of foam from a layer of volatile hydrocarbon liquid floating on an aqueous fluorosurfactant solution. By investigating the underlying processes, we demonstrate the unique ability of fluorosurfactants to form foams. Additionally, we examine the mechanisms of foaming using experiments with a single hydrocarbon droplet floating on the aqueous solution.

Summary: This article investigates the relationship between size distribution of facet areas and bubble size in aqueous foams. The study reveals that surface measurements tend to overestimate polydispersity and the mean equivalent diameter of the facets is 6% smaller than the bubble diameter obtained through sampling. The proposed method by Wang and Neethling offers a good approximation for reducing uncertainties in surface-based bubble size measurements.

Summary: In this study, mass transfer rates of single carbon-dioxide bubbles with chemical absorption in a vertical pipe using aqueous sodium hydroxide solutions were investigated. The enhancement factor E was found to be related to pH and bubble diameter, and a correlation for E was developed. By combining this correlation with Sherwood number correlations, accurate estimation of Sherwood number for bubbles with chemical absorption was achieved. Additionally, the applicability of the correlations to bubbles in a larger pipe diameter was examined.

Summary: Experimental investigations of Marangoni flow in micro-foams have faced challenges due to the difficulty in detecting and measuring this flow. This study introduces three-dimensional models to analyze the Marangoni flow characteristics in microscale foams. The simulations show that the Marangoni flow velocities are at the same scale with the PB flow velocity for mobile interfaces, but considerably less for rigid interfaces. Thicker films have a stronger effect in reducing the Marangoni flow compared to the PB flow.

Summary: This study investigates the use of commercial microfiltration membranes combined with single particle inductively coupled plasma-mass spectrometry (SP-ICP-MS) to remove environmental matrix interference and determine the concentration of model silver nanoparticles (AgNPs). Different pore sizes (0.22 μm, 0.45 μm, 0.8 μm) and materials (mixed cellulose ester, polyether sulfone, and nylon) of filters were tested for recovery of AgNPs concentration and size in various real aqueous solutions. The maximum recovery of nanoparticle concentration was 70.2% using a 0.8 μm polyether sulfone membrane. Heating the filters improved the recovery of AgNPs particles in the real aqueous environment. Therefore, the proposed pretreatment method by SP-ICP-MS combined with filtration membrane is a simple, fast, and cost-effective approach for quantifying AgNPs in natural water environments.

Summary: The study focuses on experimental investigation of droplets rising through viscous liquid, observing that droplets change shape from prolate to oblate spheroids as they mix with the ambient liquid, with their volume increasing and velocity decreasing according to power laws. The scaling relations explain the observed phenomena, but further investigation is needed on the power laws governing the rate of volumetric increase and velocity decrease.

Summary: This study investigated the influence of an emulsion's physical characteristics on the delivery onset of microinfusion. The results showed that when the emulsion entered a vertical upward carrier flow, rapid initial emulsion delivery occurred, exceeding the predictions of delivery models. On the other hand, entering horizontal and vertical downward carrier flows resulted in longer delivery lag times. These findings have important clinical implications for the efficacy and safety of using emulsion drugs.

Summary: We developed a myeloid cell-based strategy using backpack-laden monocytes to reduce disease burden in experimental autoimmune encephalomyelitis (EAE), a mouse model of progressive multiple sclerosis (MS). These backpack-laden monocytes regulated both the local and systemic immune responses and had therapeutic benefits by improving motor function. This approach offers a biomaterial-based method to precisely tune cell phenotype and demonstrates the utility of myeloid cells as a therapeutic modality and target.

Summary: In this study, the influence of transition metal doping on the electronic and mechanical properties and electrochemical performance of 2HMoS2/NC was investigated using Cobalt (Co) as an example. Co doping was found to effectively improve the electronic conductivity and active site areas of 2H-MoS2/NC at different positions, optimizing the adsorption and diffusion capability of potassium ions. Furthermore, the study revealed the optimal roles of different types of nitrogen atoms in kinetic adsorption, diffusion, and interfacial stability of potassium ions. These findings provide guidance for the experimental design of high rate 2H-MoS2/NC electrode materials and the optimal design of other functional composite materials.

Summary: This research developed an effective approach to enhance the charging rates of lithium ion batteries (LIBs) by strategically incorporating carbon nanotube (CNT) conductivity boosters into Li4Ti5O12 (LTO) electrodes. Multi-layer architectures comprising CNT-rich and CNT-free LTO electrode layers were manufactured using a layer-by-layer spray coating method to promote charge transfer kinetics of high mass loading electrodes. The best performing multi-layer was paired with a spray-coated LiFePO4 (LFP) positive electrode, resulting in attractive power performance that outperformed conventional LTO || LFP combinations.

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.
