In this study, the feasibility of preparing novel Ca-doped high entropy La(Co,Cu,Fe,Mn,Ni)O3-delta perovskites by mechanochemical synthesis was explored. It was found that monophasic compounds can be obtained after 150 h of milling, characterized by the nano size of their crystals and a significant concentration of oxygen vacancies, likely due to the incorporation of bivalent cations…
Ciprofloxacin (CIP) is a highly persistent antibiotic whose presence in natural aquatic matrices represents a critical challenge for public health and environmental protection. In this study, the photocatalytic efficiency of ZnO and its Ag-modified counterpart, synthesized by coprecipitation and photodeposition, respectively, was evaluated in the ciprofloxacin elimination in distilled water and in a real matrix…
The plant cuticle acts as the first protective layer against external biotic and abiotic factors. As such it plays a role during postharvest regulating fruit quality and shelf-life. This study is focused on understanding the changes naturally occurring in the fruit cuticle of two tomato cultivars during postharvest at ambient temperature. A notable decrease in…
This study proposes a dual-purpose strategy that integrates turquoise H-2 production with the valorization of carbon nanostructures (CNSs) obtained from CH4 pyrolysis for use as asphalt modifiers. Ni-Cu-Al catalysts with different Ni/Cu ratios (0.5-4.0) were synthesized via combustion and evaluated for CH4 pyrolysis at 700 degrees C. The catalyst with Ni/Cu = 0.5 achieved 83…
Triboelectric nanogenerators (TENGs) have rapidly developed into a transformative energy harvesting technology, enabling self-powered, sustainable electronic systems. This review offers the first comprehensive, multidisciplinary perspective that connects the physics of triboelectric charge transfer with material innovation, device engineering, and real-world applications. We systematically categorize and measure the triboelectric series across a wide range of materials,…
Ferroelectric polymers reinforced with noble metals enable advanced sensors, photodetectors, flexible electronics, and energy harvesters. This study investigates the effects of integrating hexagonal nanogold (n-Au) into poly(vinylidene fluoride) (PVDF), a prominent ferroelectric polymer, to advance the structure-property relationship in hybrid materials for next-generation sensor and energy conversion technologies. The fabricated Au-PVDF thin films (<= 100…
Ensuring the thermal reliability of luminescent materials is a key requirement for next-generation lighting, display, and sensing technologies. The intricate interplay of thermal crossover and thermal ionization in lanthanide-doped phosphors often obscures their individual contributions. We present a frequency-domain photoluminescence analysis that disentangles these competing mechanisms. Using single crystals of SrAl2O4:Eu2+,Dy3+ (SAO:Eu,Dy) and (Gd0.33Y0.67)3Al2.4Ga2.6O12:Ce3+,Cr3+ (GYAGG:Ce,Cr)…
Silver nanoparticles stabilized by amino acid-derived N-heterocyclic carbenes, denoted as Ag(NHCR)-NPs (R = H, 3a; Me, 3b; iPr, 3c; and iBu, 3d), were synthesized by reducing the parent complexes Na3[Ag(NHCR)2] (2a-d) with NaBH4 under appropriate reaction conditions. The stability of the aqueous AgNP solutions was found to depend strongly on the presence of the NHC…
The removal of heavy metals from water is a critical challenge because of their high toxicity, persistence, and bioaccumulation in biological systems. Adsorption is widely recognised as a cost-effective and efficient treatment method, and equilibrium isotherms are essential for evaluating the performance of adsorbents. Here, the equilibrium isotherms of Pb2+, Cd2+ and Hg2+ adsorbed onto…
This study introduces a dual strategy that combines kinetic modeling and advanced machine learning (ML) models to enhance the prediction and optimization of Rhodamine B (RhB) degradation using an H2O2/UV system. As a novel scientific contribution, we report the first-time synthesis of an iron-based catalyst, integrating α-Fe2O3 with structural ions (SO₄2−, OH−, Cl−), synthesized via a…
