Highly flexible and robust self-standing covalent organic framework (COF) membranes with rapid preparation are important but technically challenging for achieving precise separation. Herein , a novel imine-based 2D soft (SCOF) membrane large area of 226.9 cm2 via ingeniously selecting an aldehyde linker trigonal building block, is reported. The rapidly formed (≈5 min) based on the sodium dodecyl sulfate (SDS) molecular channel constructed at water/dichloromethane (DCM) interface, which...

Abstract. This study investigates the performances of different optical indices to estimate gross primary production (GPP) herbaceous stratum in a Mediterranean savanna with nitrogen (N) and phosphorous (P) availability. Sun-induced chlorophyll fluorescence yield computed at 760 nm (Fy760), scaled photochemical reflectance index (sPRI), MERIS terrestrial-chlorophyll (MTCI) normalized difference vegetation (NDVI) were from near-surface field spectroscopy measurements collected using high...

Abstract The precise manipulation of the microstructure (pore size, free volume distribution, and connectivity free‐volume elements), thickness, mechanical characteristics membranes holds paramount significance in facilitating effective utilization self‐standing membranes. In this contribution, synthesis two innovative ester‐linked covalent–organic framework (COF) is first reported, which are generated through selection plant‐derived ellagic acid quercetin phenolic monomers conjunction with...

Thin-film composite (TFC) membranes have gradually replaced some traditional technologies in the extraction, separation, and concentration of high value-added pharmaceutical ingredients due to their controllable microstructure. Nevertheless, devising solvent-stable, scalable TFC with permeance efficient molecule selectivity is urgently needed improve separation efficiency process. Here, we propose phenolphthalein, a commercial acid-base indicator, as an economical monomer for optimizing...

Continuous covalent organic framework (COF) thin membranes have garnered broad concern over the past few years due to their merits of low energy requirements, operational simplicity, ecofriendliness, and high separation efficiency in application process. This study marks first instance fabricating two distinct, self-supporting COF from identical building blocks through solvent modulation. Notably, precision membrane's capabilities is substantially enhanced by altering pore alignment a random...

A new machine learning method referred to as F-score_ELM was proposed classify the lying and truth-telling using electroencephalogram (EEG) signals from 28 guilty innocent subjects. Thirty-one features were extracted probe responses these Then, a recently-developed classifier called extreme (ELM) combined with F-score, simple but effective feature selection method, jointly optimize number of hidden nodes ELM subset by grid-searching training procedure. The compared two classification models...

Artificial Intelligence (AI) systems are increasingly intertwined with daily life, assisting users in executing various tasks and providing guidance on decision-making. This integration introduces risks of AI-driven manipulation, where such may exploit users' cognitive biases emotional vulnerabilities to steer them toward harmful outcomes. Through a randomized controlled trial 233 participants, we examined human susceptibility manipulation financial (e.g., purchases) conflict resolution)...

The threshold pressure is critical to characterizing multi-phase nonlinear flow through tight porous media under effective stress. Due the complex and heterogeneous pore structures, essential controls on of are not determined. In this study, based fractal theory, a theoretical model for gas–water two-phase proposed. derived considers stress, capillary pressure, boundary layer. predicted from developed in good agreement with available experimental results, which validates model.
