However, the high catalytic performance using stable electrocatalysts in alkali solutions remains limited. In this work, we herein report a facile method of deposition of NiAl-LDH electrocatalyst that addresses the above challenge under a magnetic field. Water oxidation behavior of the new electrodeposited nickel‑aluminum layered double hydroxides (NiAl-LDH) on Ni electroplated on the Cu substrate and their remarkable improvements in electrocatalytic activity under the external magnetic fields in alkali solutions were studied. Ni films were first electroplated on the Cu substrate using the direct current (DC) method. NiAl-LDH was coated on the Ni/Cu substrates using the electrochemical deposition method, and their water oxidation performance was investigated in the KOH aqueous solution (0.1 mol⋅L⁻¹) at 25 °C in the absence and presence of magnetic field. It was found that the oxygen evolution reaction (OER) over NiAl-LDH/Ni/Cu was improved when water oxidation was conducted under a magnetic field (<em>μ</em>_oH_┴ = 0.2 T) by decreasing the onset potential, Tafel slope, and overpotential or by increasing the current density (about 54 mA⋅cm⁻²). The effects were even more pronounced when the magnetic field was applied perpendicular to the electrode plane, reaching the OER overpotential of about 310 mV and the Tafel slop of about 142 mV⋅dec⁻¹. We interpreted the effect of magnetic water electrolysis by the ordinary magnetohydrodynamics (MHD) which enhanced the mass transport, increased the limiting current density, and removed the blocking oxygen gas bubbles accumulated on the electrode surface. The present investigation provides a low-cost electrocatalyst system for efficient electrochemical water oxidation.</div></div>","PeriodicalId":245,"journal":{"name":"Applied Clay Science","volume":"269 ","pages":"Article 107770"},"PeriodicalIF":5.3,"publicationDate":"2025-03-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143527124","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"地球科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The aim was to determine most effective inorganic component for developing desired elasticity and swelling/shrinking ability. By fixing the concentration of clay minerals embedded in CPNs as 1.50 % (<em>w</em>/<em>v</em>), the effect of inorganic clay type on structural properties was evaluated in terms of polymerization temperature, compressive elasticity, pH and thermo-sensitivity. Clay type had an effect on the thermal stability of semi-IPNs, while sepiolite increased the stability and compressive modulus to a higher extent. Among the four types of semi-IPNs, the water absorbency of montmorillonite-integrated gel was the highest, while that of sepiolite-doped was the lowest. The elastic moduli of semi-IPNs incorporated with same amount of clay is in the order Sepiolite &gt; Halloysite &gt; Laponite &gt; Montmorillonite. Changing pH in the range of 2.1 to 11.2 significantly increased the swelling, while a small variation in pH 6.6 caused a large difference in swelling capacity. For pH-dependent cyclic swelling, the highest swelling-shrinkage response was observed in Laponite-doped cryogels. The swelling of nanocomposites was significantly weakened by the change in ionic strength, while the swelling increased with the incubation temperature, showing good agreement with Fickian diffusion. Among the nanocomposites for cationic methylene blue (MB) dye, Laponite-integrated semi-IPNs exhibited the highest adsorption capacity from aqueous solution with 89.51 mg/g. MB adsorption kinetics followed pseudo-second-order, Freundlich and Redlich–Peterson isotherm models. The findings provide strategic approach for promising material design, supporting the development of potential applications of polyelectrolyte semi-IPN nanocomposite cryogels as biomedical materials.</div></div>","PeriodicalId":245,"journal":{"name":"Applied Clay Science","volume":"269 ","pages":"Article 107763"},"PeriodicalIF":5.3,"publicationDate":"2025-02-26","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143488395","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"地球科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

This uncertainty stems from a limited understanding of the compositional substitution mechanisms that control spectral variations. This study compiled published datasets of white mica with both available composition and spectroscopy data from five major hydrothermal systems, including porphyry, epithermal, skarn, orogenic, and volcanogenic massive sulfides (VMS) deposits. Three types of white micas, each dominated by distinct substitution mechanisms—interlayer-dominated (Na⁺ ↔ K⁺, and Ca²⁺, Ba²⁺ ↔ 2 K⁺), Tschermak-dominated (^VIAl³⁺ + ^IVAl³⁺ ↔ ^VIFe²⁺, ^VIMg²⁺ + ^IVSi⁴⁺), and illitic-dominated (K⁺ + ^IVAl³⁺ ↔ ^IVSi⁴⁺ + []_interlayer)—have been identified, accounting for the observed inconsistencies in spectral responses. The interlayer substitution is associated with shorter absorption feature (&lt; 2195 nm) arising from the combination of high-frequency Al₂OH stretching (<em>ν</em>) vibration and bending (δ) vibration. Interlayer-dominated white mica is predominantly found in orogenic deposits, where its presence typically indicates proximal mineralization. Tschermak substitution induces continuous wavelength shifts (2195–2215 nm) in the mid-frequency <em>ν</em> region combined with δ vibration. A high-level of Tschermak reaction stimulates low-frequency ν vibration, producing specific longer absorption feature (&gt; 2215 nm) with δ vibration. Tschermak-dominated white mica is the most widespread among diverse systems. Illitic substitution, however, leads to compositional changes that are not detectable in shortwave infrared (SWIR, 1300–2500 nm) regions, thus rarely providing vectoring indicators. This study suggests that data from white mica characterized by different dominant substitution mechanisms should be distinctly evaluated, thereby enhancing the efficacy of SWIR spectroscopy for mineral exploration.</div></div>","PeriodicalId":245,"journal":{"name":"Applied Clay Science","volume":"269 ","pages":"Article 107762"},"PeriodicalIF":5.3,"publicationDate":"2025-02-26","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143488397","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"地球科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
