Summary: In this study, a high cumulative true strain was applied on a near equiatomic NiTi shape memory alloy through multi-axial forging, resulting in a full shape memory response without residual strain under decreasing temperature conditions. The effects of compound twins on stabilizing the pre-existing martensite structure and favoring the detwinning stage compared to type I and type II deformation twins were discussed as important factors in this behavior.

Summary: Local canning compression is applied to equiatomic NiTi shape memory alloy with complete B19' martensite, leading to different grain sizes after annealing at 300, 450 and 600 degrees C. The highest elastic limit is achieved under annealing at 300 degrees C, while the highest yield stress and good plasticity are observed under annealing at 450 degrees C. Annealing at 600 degrees C results in a relatively low yield stress but still higher than the as-received NiTi SMA, with high plasticity as well.

Summary: This study evaluated the corrosion effects on fracture of nickel-titanium superelastic wires in physiological solutions, showing localized corrosion in fluoride-containing solutions but no corrosion in NaCl solutions. The corrosion resistance of strained and unstrained wires did not differ significantly, yet brittle-like fracture was observed in solutions with both NaCl and NaF. The use of superelastically strained NiTi in oral environments with fluoride poses a significant risk of corrosion-induced fracture.

Summary: The correlation between the surface chemistry and corrosion behavior of quaternary CuAlMnGd and CuAlMnSn alloys was investigated. It was found that the addition of Sn promoted the formation of a homogeneous microstructure, while the presence of Gd led to the formation of different crystalline phases. XPS analysis revealed the presence of Gd2O(3) and/or Gd(OH)(3) on the surface film of the CuAlMnGd alloy, and SnO2 on the surface of the CuAlMnSn alloy. Electrochemical tests showed that the Sn-containing alloy exhibited better corrosion resistance.

Summary: In this study, the use of electrochemical oxidation with upcycled secondary waste materials (SWMs) as electrodes was demonstrated as a safer and cleaner technology to minimize the impact of pharmaceuticals in wastewaters. The design of tailored multifunctional electrode materials, derived from combustion and industrial processes, addresses the energy efficiency and potential release of toxic by-products issues. The results show that SWMs can substitute costly engineered fillers and the tailored fibrous composite electrodes have low energy consumption and absence of reaction by-products, making them good candidates for safer and cleaner technologies.

Summary: In this study, a series of MnCo2-xFexO(4) powders were synthesized by the sol-gel method to investigate the effect of partial Fe substitution on the physicochemical and electrochemical properties of MnCo2O4 spinel. The synthesized powders were characterized using various techniques. The findings revealed that the electrocatalytic activity towards oxygen evolution reaction (OER) was enhanced when Fe was partially substituted for Co, with the highest activity observed at x = 0.5. This indicates that tuning the eg occupancy at the octahedral sites through Fe substitution can modulate the catalytic activity of OER.

Summary: This study investigated the multiple reprocessing of a commercially available PLA conductive composite with carbon black filler for 3D printing. The effects of extrusion temperature and reprocessing steps on the rheology, morphology, thermal, and electrochemical properties of the conductive PLA 3D-printing filament were evaluated. The results showed deterioration in thermal stability and material strength, as well as an increase in melting point after initial melting. The conduction mechanism and reversibility of the redox process were also affected by the multiple processing. Furthermore, the material fluidity was too high after multiple reprocessing, which should be considered for proper application as a 3D-printed electrode material.

Summary: Anodic TiO2 nanotubes have potential for large-scale production due to their high specific surface area and easy growth. In this study, a fast 30-second nitrogen plasma-induced crystallization method was proposed for TiO2 nanotubes. The method showed comparable photoresponse to furnace annealed TiO2 nanotubes without significant changes in their ordered morphology. This method demonstrates promise for reproducible and stable fabrication of photoanodes and could contribute to wider applications of plasma for phase transitions in functional materials.

Summary: In recent years, there has been a significant increase in the number of studies focusing on the synthesis and characterization of deep eutectic solvents (DESs). DESs, known for their stability, ease of synthesis, and ability to tailor properties, are considered one of the greenest solvent families used in various fields such as organic synthesis, catalysis, electrochemistry, and medicine. However, there is a lack of research on specific groups of DESs, particularly those comprising organic acids (OA-DESs), despite their potential in biomedical applications. This review aims to highlight the importance and applications of OA-DESs as antimicrobial agents and drug delivery enhancers, providing valuable insights for future developments in this field.

Summary: In this work, the electropolymerization of quinone-rich polydopamine (PDA) on hydrogenated TiO2 nanotubes is described, resulting in improved photoactivity in the visible spectrum. The deposition of PDA is uniform on the nanotube walls and its chemical structure depends on the pH of the supporting electrolyte. The modification of the nanotubes leads to a 20-fold increase in photocurrent response and improvement in quantum efficiency at specific wavelengths.

Summary: The electrodes with a periodic matrix of gold particles patterned by titanium dimples and modified by 3-mercaptopropionic acid (MPA) followed by CD147 receptor grafting were studied for specific impedimetric detection of SARS-CoV-2 viral spike proteins. The study revealed that MPA adsorption on the Au-Ti surface had preferential and stronger binding patterns with CD147, resulting in enhanced surface coverage. Control of bonding at the surface was crucial for oriented receptor assembling and boosted sensitivity. The method has been demonstrated for detecting the SARS virus and can be applied to protein-antigen systems.

Summary: The impact of crystallinity on the structural, thermal, and in vitro dissolution properties of Na2O-CaO-Nb2O5/MgO-P2O5 glasses/glass-ceramics was investigated. Glass-ceramics were synthesized through spontaneous crystallization. The Nb content in the materials increased with melting temperature, and the crystallinity was directly proportional to the Nb content. FTIR analysis confirmed the presence of crystalline niobates and phosphates, which was consistent with XRD results. The phosphate network was found to consist of different proportions of Q2, Q1, and Q0 units, depending on the amount and type of crystalline phase. Most samples exhibited improved thermal stability. The in vitro dissolution test showed that the highest mass loss occurred within the first 6 days of immersion, with smaller phosphate crystals favoring the deposition of hydroxyapatite while larger niobate crystals dissolved more readily.

Summary: Salivary stones, also known as sialoliths, are formed in pathological conditions in the salivary glands. The composition of sialoliths and the proteins associated with their formation have been studied using mass spectrometry and SWATH-MS analysis. Different types of sialoliths were found to contain unique proteins, and bacterial proteins were also identified. The results suggest that bacterial infections, disturbances in calcium metabolism, and neutrophil extracellular traps (NETs) may play a role in the formation of sialoliths.
