A newly synthesized 1,3-alternate calix[4]arene-based fluorescent chemosensor featuring pyrene–thiosemicarbazone units was developed and characterized as an effective 1:1 binding platform for the sensitive detection of Cd(II), Ni(II), and Cu(II) ions through pronounced fluorescence quenching.
This paper reports the successful synthesis of highly active nanocrystalline Sr12Al14O33 and Ca12Al14O33 soot oxidation catalysts via a low-temperature reaction of metal oxides with water and AlOOH, with the strontium variant demonstrating superior performance due to enhanced oxygen radical mobility.
This study develops a unified Cubic-Plus-Association equation-of-state framework that accurately predicts the vapor–liquid equilibria of isobutanol, 1-butanol, and 2-ethyl-1-hexanol mixtures by explicitly accounting for hydrogen bonding and steric hindrance effects through physically interpretable parameters.
This study developed and validated rapid, field-deployable chromogenic spot and test-tube assays for qualitative zinc detection in fortified wheat flour, demonstrating high accuracy and agreement with ICP-MS reference methods to enable effective routine monitoring in resource-limited settings.
This study demonstrates that graphene/pure ferrite composite absorbers, prepared via a hydrothermal method with a 1:3 mass ratio, achieve optimal microwave absorption performance (−23.8 dB at 11.8 GHz) through a synergistic mechanism of enhanced magnetic and dielectric losses driven by interfacial polarization and multiple reflections.
This study demonstrates that two curcumin-derived Schiff base ligands, CurAP and CurMP, serve as effective and selective colorimetric chemosensors for the visual detection of Cu²⁺, Fe²⁺, and Pb²⁺ ions in an aqueous-DMF mixture through the formation of 1:1 bidentate complexes, a mechanism further supported by conceptual density functional theory analysis.
This study demonstrates that ammonium phosphomolybdate (AMP) and natural zeolite immobilized in alginate microcapsules are effective, stable adsorbents for cesium removal from simulated seawater, with AMP-alginate exhibiting superior distribution coefficients and adsorption capacity compared to natural zeolite-alginate.
This study combines high-throughput DFT screening, machine learning, and experimental validation to identify Ni₁₉@N₄C as a highly active, earth-abundant electrocatalyst for the oxygen evolution reaction, establishing local frontier orbital occupancy as a key descriptor for rational nanocluster design.
This study demonstrates that despite being structurally detectable, chemically short-range order (CSRO) in FCC alloys like CoCrNi and Inconel 625 remains functionally silent regarding hydrogen diffusivity and embrittlement, thereby establishing a fundamental limit to its utility as a design lever for hydrogen-resistant materials.
This study demonstrates that incorporating 15 wt% hydrophobic silica aerogel into waterborne intumescent coatings optimally balances enhanced thermal insulation and active high-temperature residue modification with acceptable mechanical adhesion, establishing a rational strategy for next-generation fire-protective coatings that address both fire safety and building energy performance.
