To enhance the mechanical properties of hydrogels, this study prepared a composite hydrogel (P-D₃₀-DIOH₁) composed of covalently crosslinked polyacrylamide (PAM), diacetone acrylamide (DAAM), and expanded dickite (DIOH). The results indicated that PAM and DAAM could form a dual crosslinked network structure through hydrogen bonding and molecular chain entanglement, thereby improving the mechanical properties of the hydrogel. Furthermore, the surface of dickite, which is rich in -OH and Si<img>O groups, could simultaneously form hydrogen bonds with PAM and DAAM, thus acting as an inorganic crosslinking agent. After expansion treatment, the dickite layers were fully exposed, increasing the specific surface area and further enhancing the physical crosslinking effect of dickite. Mechanical testing revealed that the tensile strength of the DAAM and DIOH reinforced P-D₃₀-DIOH₁ hydrogel reached 0.374 MPa, with a tensile elongation of 2100 % and a compressive strength of 0.308 MPa at 75 % deformation. P-D₃₀-DIOH₁ hydrogel electrolyte exhibited a high ionic conductivity (20.7 mS cm⁻¹), attributed to the negatively charged expanded dickite, which enriched Zn²⁺ and formed rapid Zn²⁺ transport channels under the electric field. The P-D₃₀-DIOH₁ hydrogel effectively stabilized the surface of the Zn anode, inhibited the growth of Zn dendrites, and reduced the formation of by-products. When the P-D₃₀-DIOH₁ hydrogel electrolyte was assembled into the MnO₂//Zn battery, it operated stably for 700 cycles, maintaining a specific discharge capacity of 118 mAh g⁻¹ at a current density of 150 mA g⁻¹. Moreover, the battery delivered a specific discharge capacity of 270 mA h g⁻¹ at 60 mA g⁻¹, and even at 600 mA g⁻¹, it retained a high reversible capacity of 115 mAh g⁻¹, demonstrating excellent electrochemical performance.

Two different sizes (fine and coarse) and three percentages (10, 20, and 30 % by weight) of volcanic ash were added to a clayey sediment from Viznar (Granada, Spain) to produce bricks that were fired at 800, 950, and 1100 °C in an electric oven with an oxidising atmosphere. The chemistry, mineralogy and texture of the samples with volcanic ash were compared to control samples made without it and fired at the same temperature. In the bricks with ash there was a reduction in the phases detected in the control samples (quartz, phyllosilicates, and newly formed gehlenite, and diopside) and augite, a phase present in the volcanic ash, appeared. The volcanic ash fragments in the samples fired at over 950 °C turned red in color, owing to the formation of iron oxides. The increase in the concentration of volcanic ash caused a progressive increase in the vitreous phase and in clinopyroxene. Conversely, there were no significant differences in terms of their mineralogical composition between the fired bricks made with fine or coarse ash, although the samples with coarse volcanic ash apparently showed higher porosity.</div></div>","PeriodicalId":245,"journal":{"name":"Applied Clay Science","volume":"266 ","pages":"Article 107690"},"PeriodicalIF":5.3,"publicationDate":"2024-12-31","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143137495","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}

Reflectance spectra, CIE color parameters, surface properties, and Fourier-transform infrared spectroscopy were employed to evaluate these pigments. Results indicate that indigo monomers can penetrate the channels of both palygorskite and sepiolite, conferring a greenish-blue hue and high stability. However, the diffusion of indigo is determined by the size match between the channel and indigo monomers. In palygorskite, indigo monomers can diffuse only upon heating because the channel size is only a little bit larger than the indigo molecule, while in sepiolite, lager channels allow easy diffusion, even without heating. However, sepiolite's larger channels make indigo molecules more prone to chemical degradation or migration. Under vacuum conditions, indigo molecules more easily diffuse into the channels of both clay minerals, yielding pigments with higher saturation and enhanced stability. These findings highlight the size-matching between clay minerals' micropores and organic molecules and offer valuable guidance for optimizing the preparation process of clay-dye hybrid pigments.</div></div>","PeriodicalId":245,"journal":{"name":"Applied Clay Science","volume":"265 ","pages":"Article 107689"},"PeriodicalIF":5.3,"publicationDate":"2024-12-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143155232","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}

Further, it plays a crucial role in monitoring the disease propagation during the pandemic. A wide range of analytical methods are used to detect and quantify viruses. The currently available methods are, however, laborious, costly, and time-consuming. Also, the accuracy of many of these methods is debatable. We propose a novel method for the detection and quantification of coronavirus based on the clay–virus–electrolyte interaction using the sedimentation method. Newcastle disease virus (NDV), a Coronavirus surrogate (CS), and Infectious bronchitis virus (IBV), an avian coronavirus, were used in this study. Due to changes in inter-particle forces of clay in the presence of the virus, the sedimentation rate of the clay-electrolyte system changed. A protocol was thus developed based on the changes in the sedimentation rate to predict the presence and quantity of the given virus. The sedimentation rates were recorded by mixing the bentonite clay with the CS or IBV and 0.1 M NaCl electrolyte solution at a solid-to-liquid ratio of 1:50. The sedimentation rates were varied with different CS concentrations due to different particle-particle associations due to the sorption of virus particles on the clay surface. The proposed method was successfully validated for using the plaque assay techniques for CS virus and RT-PCR for the IBV. The proposed method is simple, cost-effective, and very useful for the detection of coronavirus and other viruses' presence and quantification. Moreover, the methodology is useful to diagnose the Newcastle disease virus (NDV), which causes infection among several avian species during avian outbreaks.</div></div>","PeriodicalId":245,"journal":{"name":"Applied Clay Science","volume":"265 ","pages":"Article 107680"},"PeriodicalIF":5.3,"publicationDate":"2024-12-25","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143155823","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}
