Walnut shells were used to produce highly microporous activated carbon. The prepared walnut found be an efficient adsorbent for removing Cr(VI). study the response surface methodology investigate four independent variables effect: Cr(VI) concentration, pH, AC-Ws dose, and temperature on removal efficiency, which was studied in concentration range of 0.1 0.3 g/L, 4 10, 15 35 °C 1 5 mg/L, respectively. Through experiments designed, optimum conditions determined 4, 0.23 298 k, 2 At these conditions, efficiency 93%. thermodynamic adsorption process showed a spontaneous exothermic nature. kinetic model that explains experimental data is pseudo-second-order model. Furthermore, Langmuir isotherm estimated excellent representation equilibrium data. Quantum calculations NCI analyses also performed get more light mechanism atom its complex form surface.

Selective detection of food contaminants using engineered gallium-organic frameworks with MD and metadynamics simulations

Scientific Reports, Год журнала: 2024, Номер 14(1)

Опубликована: Авг. 5, 2024

The exclusion mechanism of food contaminants such as bisphenol A (BPA), Flavonoids (FLA), and Goitrin (GOI) onto the novel gallium-metal organic framework (MOF) functionalized MOF with oxalamide group (MOF-OX) is evaluated by utilizing molecular dynamics (MD) Metadynamics simulations. atoms in molecules (AIM) analysis detected different types atomic interactions between contaminant substrates. To assess this procedure, a range descriptors including interaction energies, root mean square displacement, radial distribution function (RDF), density, hydrogen bond count (HB), contact numbers are examined across simulation trajectories. most important elements stability systems under examination found to be stacking π-π HB interactions. It was confirmed significant value total energy for BPA/MOF-OX (- 338.21 kJ mol

Exploring Principal Component Analysis for Enhanced Insights into Physical and Operational Characteristics of Palladium-Based Membrane Composites: Advancing Hydrogen (H2) Energy Potential to Revolutionize the Energy Sector

Processes, Год журнала: 2025, Номер 13(1), С. 192 - 192

Опубликована: Янв. 11, 2025

In this study, we used Principal Component Analysis (PCA) to evaluate the physical and operational properties of palladium (Pd)-based membrane composites, focusing on variables like temperature, differential pressure (ΔP), thickness, hydrogen (H2) permeability, H2 flux. The analysis revealed that first two principal components explained 53.16% total variance, indicating moderate explanatory power. Interdependencies were observed among flux, while ΔP functioned independently. This study found similarities membranes, such as eco-friendly chitosan-based which performed comparably conventional options Pd–PSS Pd–Cu/αAl2O3. Overall, PCA proved be an invaluable tool for uncovering hidden patterns, optimizing experimental processes, deepening understanding Pd-based membranes. findings underscore PCA’s potential enhance material performance promote sustainable alternatives, with practical benefits advancing separation technologies. illustrates how data-driven approaches can refine drive innovation in design.

Alginate versus Chitosan for Templating Growth and Shaping HKUST‐1 as Porous CO₂‐Adsorbent Beads

ChemistrySelect, Год журнала: 2025, Номер 10(5)

Опубликована: Фев. 1, 2025

Abstract This study aims at elucidating the role of polysaccharide skeleton (alginate versus chitosan) during growth and shaping HKUST‐1 as porous beads. Although two biopolymers afford an open hydrogel network, freeze‐drying step was crucial with water medium being inappropriate to preserve crystalline framework HKUST‐1. Alternatively, drying in ethanol circumvented this drawback by keeping intact structure However, a contrasting behavior observed resulting polysaccharide@HKUST‐1 beads, grown alginate underwent dramatic collapse, whereas self‐standing, microspheres could be obtained using chitosan templating route. The chitosan@HKUST‐1 cryogel displays enhanced CO 2 capture (2.67 mmol.g −1 ) compared its analogs shaped alginate, making consequently better option for structuring MOF‐based adsorbents.
