Preparation Methods and Photocatalytic Performance of Kaolin-Based Ceramic Composites with Selected Metal Oxides (ZnO, CuO, MgO): A Comparative Review

Inorganics, Journal Year: 2025, Volume and Issue: 13(5), P. 162 - 162

Published: May 13, 2025

The current review examines various methods for preparing photocatalytic materials based on ceramic substrates, with a focus incorporating metal oxides such as ZnO, CuO, and MgO. This study compares traditional mixing, co-precipitation, sol–gel, autoclave synthesizing these materials. Kaolin-based ceramics (DD3 DD3 38% ZrO2) from Guelma, Algeria, were used substrates. highlights the effects of different preparation structural, morphological, compositional properties resulting photocatalysts. Additionally, potential degradation organic dyes, specifically Orange II, was evaluated. Results indicated that ceramic/ZnO/CuO ceramic/MgO powders prepared via mixing co-precipitation techniques exhibited significantly faster rates under visible light than Cu layers deposited substrates using solution gradient processes. enhancement attributed to increased effective surface area size spherical nanoparticles obtained through methods, which facilitated accelerated pollutant absorption. ease cost-effectiveness robust are advantageous applications due their straightforward removal after filtration. Notably, DD3Z/MgO demonstrated superior catalytic activity, achieving complete dye in just 10 min, whereas DD3Z/ZnO-CuO achieved 93.6% 15 min. experiments kaolin-based instead yielded maximum decomposition rate 77.76% over 6 h ZnO thin method.

3D Printed Bigel: A Novel Delivery System for Cannabidiol-Rich Hemp Extract

Gels, Journal Year: 2024, Volume and Issue: 10(12), P. 770 - 770

Published: Nov. 26, 2024

The therapeutic potential of Cannabis sativa L. extract has gained significant attention due to its diverse medical applications. Sublingual administration remains a common delivery method cannabinoids; however, challenges often arise the inconvenient form and taste. To address these issues, novel bigel formulation was developed, combining water oil phases enhance stability bioavailability. This incorporates cannabidiol-rich hemp extract, hyaluronic acid for moisturizing properties, taste-masking agent improve patient compliance comfort. Using standardized rich in cannabinoids well-characterized terpene profile, printability bigels evaluated through 3D printing technology. A printout with known cannabidiol (CBD) cannabidiolic (CBDA) content 11.613 mg ± 0.192 CBD 4.732 0.280 CBDA obtained. In addition, release profile determine efficiency active ingredient—dissolved ingredient levels ranged from 74.84% 0.50 80.87% 3.20 80.84 1.33 98.31 1.70 depending on formulation. Rheological studies were conducted evaluate viscosity under varying temperature conditions, ensuring their usability. Findings suggest that this 3D-printed could significantly cannabis extracts, offering more convenient effective option patients. research underscores importance innovation cannabinoid therapies paves way further advancements personalized medicine.

Abstract In the current investigation, elemental boron was added to form a series of Ti 53.3-x Nb 10 Zr Ni Co Fe 6.7 B x Compositionally Complex Alloys (CCAs). Alloying done via vacuum arc melting in amounts 0.0, 5.3, and 10.6 at.%. From thermodynamic parameters, adding base alloy increased system’s entropy. The microstructure prepared CCAs characterized using scanning electron microscopy, transmission X-ray diffraction (XRD). mechanical properties as related were assessed. According XRD results, B-based intermetallic phases obtained CCAs, which binary 3 4 ZrB 2 ternary FeNbB 7 . These notably provided strengthening effects B-added alloys. 48 5.3 CCA showed most homogenous by process. Adding Young’s modulus from 141 GPa (without B) 195 260 with at.%B, respectively. Hardness also 502 606 HV at.% 648 at.%B. Accordingly, wear resistance addition where at.%B sample lowest rate among other conditions. However, nominated optimum amount due its notable homogeneity.
