Modeling the separation of water‐in‐oil emulsions in continuously fed gravity settlers using millifluidic experiments

AIChE Journal, EarlyView.
Abstract Emulsion separation remains a persistent challenge in chemical and process industries due to the metastable nature of dispersed droplets. In gravity separators, the overall separation rate is governed by the formation of a densely packed zone (DPZ) of deforming and coalescing droplets that mediates between the dispersed and continuous phases ...

The Role of Shape Commensurability in Chirality Transfer: Gold Nanoshape Solutes in a Discotic Nematic Liquid Crystal Solvent

Angewandte Chemie, EarlyView.
We report on a suitable approach to predict the chirality “strength” and efficacy of chirality transfer from chiral nanoshape solutes to an achiral discotic nematic (ND) liquid crystal solvent. Highly efficacious chirality transfer based on shape commensurability between nanoshape solute (in the form of gold nanodiscs, GNDs) and a ND solvent was ...

Application of Neural Networks for Advanced Ir Spectroscopy Characterization of Ceria Catalysts Surfaces

Advanced Intelligent Discovery, EarlyView.
A novel convolutional neural network architecture enables rapid, unsupervised analysis of IR spectroscopic data from DRIFTS and IRRAS. By combining synthetic data generation with parallel convolutional layers and advanced regularization, the model accurately resolves spectral features of adsorbed CO, offering real‐time insights into ceria surface ...

Synergistic Lewis Acid Photocatalysis Over Cluster‐Defect‐Engineered UiO‐66 for Efficient Liquid Biomass Upgrading

Angewandte Chemie, EarlyView.
A cluster‐defect engineering strategy is presented for the rational design of Zn‐incorporated UiO‐66 photocatalysts. Selective acid etching mediates hierarchical porosity and abundant Lewis acid sites, tailoring the electronic structure and enhancing light harvesting.

Feasible region identification approach for the regional integrated energy system considering flexible ramping constraints based on polyhedral projection algorithm

International Journal of Electrical Power & Energy Systems
The low-carbon agenda promotes the increasing penetration of renewable energy, this however also results in a rapid decrease in the flexibility of power systems with less controllable generation.

Parametrics of Movable Polyhedral Models in Performative Architecture

, 2009
We present a parametrical approach to movable polyhedral models. Based on polyhedral geometry the whole structure consisting of an interconnected series of prisms (with dual spherical joints) can move 3-dimensionally.

Cell Segmentation Beyond 2D—A Review of the State‐of‐the‐Art

Advanced Intelligent Discovery, EarlyView.
Cell segmentation underpins many biological image analysis tasks, yet most deep learning methods remain limited to 2D despite the inherently 3D nature of cellular processes. This review surveys segmentation approaches beyond 2D, comparing 2.5D and fully 3D methods, analyzing 31 models and 32 volumetric datasets, and introducing a unified reference ...

Specific Ion Effects of Chaotropic and Superchaotropic Anions Probed by Raman Hydration‐Shell Spectroscopy

Angewandte Chemie, EarlyView.
The vibrational frequencies of “dangling” water O─H bonds can be determined by Raman hydration‐ shell spectroscopy and used to differentiate chaotropes from kosmotropes and hydrophobes. Dangling O─H bonds are also detected around superchaotropic anions of the borate cluster type (B12X122−; X = H, F, Cl, Br, and I) but their frequencies do not directly ...

Numerical Experience with a Polyhedral-Norm CDT Trust-Region Algorithm

, 1993
In this paper, we study the modification of the Celis-Dennis-Tapia trust-region subproblem which is obtained by replacing the l² norm with a polyhedral norm. The polyhedral norm CDT subproblem can be solved using a standard quadratic programming code. We
