Summary: Paper is a suitable material for developing disposable diagnostic devices due to its low cost, capillary action for liquid transport, and eco-friendliness. This study explores the use of fluorescence as a readout tool for paper-based diagnostics, which shows better optical readout compared to the current choice of colorimetric assays using nitrocellulose. Additionally, coating the paper fibers with a protein-repellent hydrogel enhances the sensitivity of paper-based analysis.

Summary: This study explores the adsorption behavior of bisphosphonates (BPs) on TiO2, hydroxyapatite (HA), and TiO2+HA composite surfaces. The impact of UV irradiation on BP adsorption was investigated through adsorption curves, revealing an increase in adsorbed BP content due to enhanced deprotonation and hydroxyl group formation. X-ray photoelectron spectroscopy (XPS) analysis indicates that BPs adsorb through condensation reactions with TiO2, while phosphate and Ca2+ ions coordinate with HA. Functionalized films exhibit a water contact angle of zero, and atomic force microscopy (AFM) measurements suggest that BP adsorption has a smaller impact on titania topography compared to HA.

Summary: This article introduces a method for electrophoretic deposition of hydroxyapatite nanoparticles on gold surfaces for surface plasmon resonance measurements. Using an artificial tooth model, the influence of natural saliva in different pH environments has been studied. The results demonstrate that even slight acid solutions can significantly damage the pellicle, exposing the hydroxyapatite to acidic degradation, which can lead to caries.

Summary: Aflatoxins are highly toxic secondary metabolites of fungi that are classified as poisonous mycotoxins. They are mainly produced by Aspergillus flavus and Aspergillus parasiticus in cereals, peanuts, and animal feeds. Sample preparation techniques, chromatographic methods, and detection techniques are crucial in aflatoxin analysis. Selectivity in analysis is achieved using bio-recognition elements like enzymes, antibodies, or DNA sequences. Determination of aflatoxins is essential for food safety due to their high toxicity and presence in food and agricultural products. The choice of analysis method depends on the sample nature, available equipment, toxin concentration range, sensitivity, detection limit, precision, selectivity, required analysis time, and personnel training.

Summary: Microfluidic paper-based analytical devices (μPADs) have gained attention for their advantages in clinical diagnostics, environmental monitoring, and food safety assurance. However, they lack high sensitivity for detecting trace analytes compared to commercial instruments like mass spectrometry. To enhance sensitivity, a preconcentration step is required. This review focuses on techniques to separate and preconcentrate analytes on μPADs, along with challenges and future perspectives.

Summary: The study evaluated the spoilage status of meagre caught in January and July through sensory, microbiological, 16S metabarcoding and VOCs analysis, revealing differences in shelf-life, microbial composition, and volatile profile between whole fish and fish fillets, as well as between the two seasons. Different microbial profiles and volatile compounds were found in the two seasons, with some compounds positively correlating with storage time and others showing a declining trend. The findings provide valuable insights for stakeholders to supply high-quality meagre products in the national and international market.

By adding paraffin-naphthenic oil, improved processability is achieved. The mechanical properties of the materials decrease with increasing waste dosage, but properties for the targeted application are maintained until 15-20% filler blend. The addition of waste leads to an increase in storage modulus and viscosity, indicating a reinforcing effect.

Summary: In recent years, various commercial coatings based on fluorinated materials have been developed using different preparation routes. However, these techniques often require expensive and complex equipment, involve multiple manufacturing steps, or are time- or cost-consuming. This study aimed to develop sustainable hydrophobic and transparent fluorinated hybrid coatings using the sol-gel method, which offers advantages such as lower cost, energy consumption, and easier implementation. The influence of perfluorooctanoic acid in the sol-gel process on the properties of the coatings was evaluated, and different silane precursors were used to synthesize hybrid silica materials. The fluorinated silica coatings showed good transparency and hydrophobicity, making them suitable for potential optical devices.

Summary: Currently, around 70% of paintings in museum collections have been affected by the presence of metallic soaps, causing surface alterations such as exfoliation, cracking, and the formation of surface skins. This study investigates the icon paintings from Saint Mary Monastery in Romania, which have undergone restoration procedures. The presence of efflorescence and its correlation with the conversion of fatty acids into metallic soaps through the reaction of metals in the pigments and binder make this study highly significant. The analysis conducted using various microscopic techniques and spectroscopy methods provides insights into the identification and quantification of metallic soaps generated as white deposits.

Summary: Obtaining photocatalytic coatings on textile materials is challenging due to the conflicting properties that need to be achieved. This study proposes a solution using hybrid silica films generated by sol-gel processes, containing TiO2 sensitized with iron (III) phthalocyanine (FeTCPc). The coatings were made using a pad-dry-cure process with various agents. Experimental results show that treatment with BORAX improves the resistance of the coatings to wet treatments but impairs their photocatalytic performances.

Summary: The corrosion behavior of Fe-60 and Fe-83 ribbons in 0.6 M NaCl was studied. Fe-60 exhibited a local corrosion mode and formed a stable passivation film with higher corrosion resistance, while Fe-83 showed a combination of local and global corrosion modes and had lower corrosion resistance. Controlling the precipitation of nanocrystalline phases and increasing the POx content in the passivation film significantly improved the corrosion resistance of Fe-based glassy alloys.
