Summary: This study investigates the wet classification behaviors of polydisperse particles using a nanofibrous membrane with a complex three-dimensional network structure and high porosity. Results show that the nanofibrous membrane effectively retains larger particles while allowing smooth passage of smaller particles. Analysis of filtration models and SEM images provides insight into the retention behavior of larger particles.

Summary: The clarity of beer is crucial for its marketability and consumer approval. This study tested natural zeolite as a substitute filter media for diatomaceous earth in removing unwanted constituents that cause beer haze formation. The results showed that natural zeolites are promising aids for beer filtration, with no significant changes in brewery industry process equipment and protocols for preparation.

Summary: Robots have components that work together to accomplish a task. Colloidal robots are particles capable of functions such as sensing, computation, communication, locomotion, and energy management that are all controlled by the particle itself. Their design and synthesis is an emerging area of interdisciplinary research drawing from materials science, colloid science, self-assembly, robophysics, and control theory.

Summary: The research team has created non-biological capsules that can capture, concentrate, store, and release microscopic payloads as needed. This design uses hollow colloids as cell-membrane mimics with a well-defined single pore, allowing for mass production and offering a blueprint for developing smart materials, micro-machinery, and artificial cell mimics.

Summary: The study shows that nanocrystalline zirconia with uniform size can be prepared by sintering zirconium gel, where colloidal particles aggregate into clusters and form a three-dimensional gel network structure. This internal gelation process is superior for preparing uniform nanocrystalline materials.

Summary: A rapid filtration test method has been developed to predict malt filtration efficiency without the need to brew. Six different malts were tested and their filtration performance was determined by measuring turbidity. Experimental results showed a correlation with viscosity and β-glucan content. The response surface design was used to optimize the detection method, leading to enhanced differentiation. The optimal reaction conditions were determined with an F-value of 147.00.

Summary: This study develops a novel experimental protocol to observe coagulant gelation using light microscopy, revealing the physical chemistry properties and the growth patterns of the gel. The research finds that the abundance of the coagulant and diffusion are key factors affecting gel growth, and the gel thickness is limited by the available amount of coagulant.

Summary: When a colloidal suspension flows in a constriction, particles deposit and can completely clog the channel, resulting in the accumulation of particles. This study investigates the factors that affect the permeability and particle volume fraction of the accumulation, including confinement dimensions, ionic strength, and flow conditions. It is found that in high confinement, the deposition of particles on the channel surfaces plays a dominant role in determining the structure and flow of the accumulation.

Summary: In this study, a simple spectral selective active colloidal system is designed, in which TiO2 colloidal species are coded with spectral distinctive dyes to form a photochromic colloidal swarm. By combining incident light with various wavelengths and intensities, the particle-particle interactions can be programmed, enabling controllable colloidal gelation and segregation. This system presents a facile approach towards colored electronic paper and self-powered optical camouflage.

Summary: Capillary assembly of liquid particles (CALP) is a microfabrication strategy for engineering arbitrarily shaped polymer colloids. CALP demonstrates versatility by engineering geometrically diverse Janus and patchy colloids using consecutive assembly and heterogeneous coassembly. It enables the design and fabrication of colloids with complex internal construction to target hierarchical functional materials, with the potential for further processing into colloid-based microscale devices.

Summary: The assembly of tunable nanocrystal gels using reversible chemical bonding and polymer-induced depletion attractions shows promise for creating functional materials with controllable properties, although challenges exist in translating principles to the nanoscale. The control of structure and properties at both microscopic and macroscopic levels is key in guiding the reversible assembly of nanocrystal gels. Insights from statistical thermodynamic theory and computer simulation have helped in predicting conditions for gelation and optimizing experimental parameters for targeted functionalities.

Summary: Patchy particles have gained attention for their ability to develop directional and selective interactions and serve as building blocks for self-assembling innovative colloidal molecules and crystalline structures. A new approach using colloidal stamps has been introduced to pattern functional DNA patches on particle surfaces, enabling selective strand-displacement reactions. These produced DNA-patchy particles are ideal candidates for advanced precision and designer building blocks to self-assemble the next generation of colloidal materials.

Summary: This study investigates the physical characteristics of sorghum whole flour particles produced through hydrothermal treatment to reduce tannins. Two types of mills were used to grind the grains with a moisture content of 25%. The results showed that the treated samples had larger particle sizes and rougher surfaces compared to the untreated samples.

Summary: This study proposes the use of pyrodextrins obtained from sorghum to improve the traditional African sorghum beer, enhancing alpha-acid utilization, bitterness, and viscosity of the drink to achieve values similar to typical lager beer obtained from barley. Addition of 10 g/L pyrodextrin resulted in a 4.4% increase in wort viscosity and a 4.9% increase in beer viscosity.
