AC is a similar approach 16 more where the absorption of visual light is traced over the whole measurement cell. Thusbeing space- and time-resolvedAC enables to investigate the interaction of the graphene flakes with different liquids in-situ.

Apparent molar mass of decanoic acid surface modified ceria nanoparticles measured by analytical centrifugation AuthorNaishu Yang, Masaki Ota, Richard Lee Smith Jr., Takaaki Tomai, Hiroshi Inomata, Masaru Watanabe Year2026 SourceFluid Phase Equilibria LanguageEnglish Pages114707 3191LUMiSizerLSHybrid nanoparticles (HNPs) are defined as particles bearing organic modifiers adsorbed or covalently bonded to their surfaces. Measurement and estimation of HNP molar mass and diffusion coefficients are essential for transport and quality control of engineering slurries 16 more as well as for catalyst dosing and advanced material formulation. In this work5.8 nm core size CeO2 nanoparticles modified with decanoic acid (C10CeO2) were prepared by supercritical hydrothermal treatment. The apparent molar mass of C10CeO2 was determined by analytical centrifugation (AC). In ACthe molar mass was obtained by analyzing the balance among the buoyancydiffusionfrictionand centrifugal forces acting on the particles during sedimentation. Specificallythe molar mass was derived from two force‑balance equations: one balancing buoyancy and diffusion against the centrifugal force (AC1)and another incorporating friction in addition to buoyancy and diffusionwhich are likewise balanced against the centrifugal force (AC2). Hybrid nanoparticles; Molar mass ; Analytical centrifugation ; SedimentationAnalytical centrifugation (AC) is a technique that applies a constant centrifugal force (gravitational field) lower than that used in AUC to a solution. Under this weaker centrifugal fieldparticles gradually approach sedimentation equilibriumwhere the opposing forces acting on the nanoparticles (primarily diffusion and centrifugal force) are balanced. AC has been successfully applied to the characterization of silica nanoparticles [29] and C10CeO2 systems [30]and it is expected to be applicable for determining the molar mass of C10CeO2 by analyzing the balance of forces involved in sedimentation. Analytical centrifugation was employed to elucidate the sedimentation behavior of decanoic acid-surface-modified ceria nanoparticles (C10CeO2) in cyclohexane. • Apparent molar mass of C10CeO2 was analyzed with the Svedberg-Lamm equationwhich considers the thermodynamic and hydrodynamic relationships among buoyancyand centrifugal forces. • A new model developed in this work accounts for friction in addition to buoyancy and diffusionwith all forces balanced against the centrifugal force.

Their discussion deepens our understanding of the prevailing microprocesses and allows a refinement of measurement protocols in future applications.Howevercommercially available photosedimentometers vary with respect to several aspects: use of gravity or centrifugal forcesgeometry of the measurement cellwavelength of the incident lighttemperature controlspatial resolution of the photometric signal or data-evaluation procedures. These differences raised questions on the reproducibility of measurement resultsfor which reason the authors organised an interlaboratory comparison (ILC) within the frame of ISO standardisation. The ILC enjoyed the participation of 24 laboratories from several countries with 26 analytical centrifuges and 10 gravitational sedimentometers. Tests were performed with a quality control material (spherical particles with narrow size distribution) and real-world materials (non-spherical particles with moderate polydispersity). Parts of the ILC have already been presented with a focus on the quantification of repeatability and reproducibility as well as on rightness of measured PSDs.

While this method proved to lower the filler concentration required to achieve electrical conductivity in solid compositesit remains unexplored for liquid conductive composites such as electrofluids (EFs). We propose the combination of emulsions and conduct- ive particles to create EFs with reduced filler content. Conductive emulsions were prepared based on two immiscible liquidsglycerol and polydimethylsiloxane (PDMS)and carbon black (CB) as the conductive filler. Analytical centrifugation The prepared emulsions were filled with a syringe into 2 mm rectangular polyamide cuvettes. The cuvettes were put into a LUMiSizer 6510Soft electronic components are of great interest for applications demanding stretchable sensors or stable conductorslike wearables or implants . Conductive polymer composites are a common type of material to create electrical conductors with relatively low Young’s modulus [5]. They consist of conductive filler particles dispersed in a non-conductive polymeric matrixoften elastomers. The high variety of conductive fillers and matrices confers on them a high versatility and a broad degree of tun- ability in their properties. For examplefillers can be found with different shapes and of different nature such as silvercopperor gold spherical particles; silver wires or flakes; carbon mater- ials such as fractal carbon black (CB)carbon nanotubes (CNTs)and graphene flakes ; or 2D materials such as MoS2 or MXenessedimentation velocityinstability index More details Edition9 Internal reference3199 Open publication →

The utilization of these systems is prevalent across a wide range of sectors within the process industry 7 more including the chemical and pharmaceutical industriesthe food technology and beverage industrybiotechnologyminerals processing and wastewater treatment [1]. An important advantage of solid-bowl centrifuges is their applicability to various particle systemssuch as colloids or coarse particles. The driving force behind the separation of dispersed particles in a continuous liquid phase is the centrifugal force which results in a density separation. This presentation provides an overview of the use of analytical centrifugation (AC) for the process design of solid-bowl centrifuges on an industrial scale.The numerical models combine short-cut models with the material functions derived from AC for the sedimentation behavior and sediment compressibility.
