ЭЛЕКТРОХИМИЧЕСКИЕ И МЕХАНИЧЕСКИЕ СВОЙСТВА БОРСОДЕРЖАЩИХ ПЭО-ПОКРЫТИЙ, ФОРМИРУЕМЫХ НА МАГНИЕВОМ СПЛАВЕ МА8 В работе представлено исследование свойств слоев, сформированных на магниевом сплаве МА8 методом плазменного электролитического оксидирования (ПЭО) в борсодержащих электролитах. Электрохимические свойства покрытий исследованы методом электрохимической импедансной спектро-скопии. Механические характеристики покрытий оценивались по величине значений микротвердости и мо-дуля Юнга. Показано, что образцы с покрытиями, формируемыми в потенциодинамических режимах, пре-восходят по показателям коррозионной стойкости сплав без покрытия более чем на1 порядок величины. Внедрение частиц бора в состав покрытий позволяет улучшить механические свойства: универсальная мик-ротвердость покрытий с частицами превышает на 10–12% величину данного параметра для базовых ПЭО-покрытий. The paper presents a study of the properties of layers formed on magnesium alloy MA8 by plasma electrolytic oxidation (PEO) in boron-containing electrolytes. The electrochemical properties of the coatings were investigated by electrochemical impedance spectroscopy. The mechanical characteristics of the coatings were esti-mated by the values of microhardness and Young's modulus. It is shown that samples with coatings formed in poten-tiodynamic modes are superior in terms of corrosion resistance to an uncoated alloy by more than 1 order of magni-tude. The introduction of boron particles into the composition of coatings makes it possible to improve the mechani-cal properties: The universal microhardness of coatings with particles exceeds by 10-12% the value of this parame-ter for basic PEO coatings Chemistry Magnesium Alloys: Properties and Applications ; Surface Treatment and Coatings ; Polymer Science and Applications

Mechanisms and Research Progress of Magnetic Nanoparticles in Modulating Neural Plasticity for Neuroregeneration Magnetic nanoparticles (MNPs), particularly those exhibiting superparamagnetism and biocompatibility, have garnered significant interest in the biomedical field due to their unique physicochemical properties. Recent studies have shown that MNPs can modulate neural plasticity by influencing key signaling pathways such as BDNF (Brain-Derived Neurotrophic Factor) and the PI3K/Akt pathway, critical for neuronal growth, synaptic connectivity, and functional recovery. This review provides a comprehensive analysis of the mechanisms through which MNPs interact with neural tissues, highlighting the diversity of nanoparticle types (eg, iron oxide, gold, and carbon-based nanoparticles) and their applications in neurodegenerative disease treatment and neural regeneration. Despite the immense potential of MNPs in neurodegenerative disease treatment, this review also compares them with traditional interventions, discussing their advantages and limitations. Additionally, it addresses key challenges, particularly the difficulty of overcoming the blood-brain barrier, and issues related to biocompatibility, toxicity, and long-term safety. In clinical applications, ethical concerns, such as patient informed consent and long-term risks, must also be considered alongside efficacy and safety. This review offers insights into these challenges and provides a framework for future research, aiming to accelerate the clinical integration of MNP-based neurotherapies.

Cellulose and Cellulose Synthase in a Marine &lt;em&gt;Pseudomonas&lt;/em&gt; Strain from Antarctica: Characterization, Adaptive Implications, and Biotechnological Potential Antarctic microorganisms have developed extraordinary strategies for adaptation. They have also demonstrated the ability to produce various biopolymers in response to environmental stress. The demand for biopolymers is constantly increasing and is expected to grow further. Among the emerging biomaterials, bacterial cellulose (BC) is generating significant interest due to its unique characteristics that distinguish it from plant-based cellulose. BC exhibits higher purity, water-holding capacity, and tensile strength compared to its plant-based counterpart. Furthermore, BC can be obtained through environmentally friendly protocols. Several bacterial strains have already been identified as cellulose producers, including Komagataeibacter xylinus. In this study, a marine bacterial strain named Pseudomonas sp. ef1, isolated from a consortium associated with the Antarctic ciliate Euplotes focardii was tested for cellulose production. We found that this Antarctic Pseudomonas can produce BC in conditions that appear unique to this bacterial strain. Furthermore, the final BC product is structurally different from that obtained from the well-known BC producer Komagataeibacter xylinus. Additionally, a putative cellulose synthase was identified from the Pseudomonas sp. ef1 genome, exhibiting unique characteristics that may account for the unique BC production capability of this Antarctic marine Pseudomonas. The versatility of BC opens numerous applications, including in papermaking, food, pharmaceutical, and biomedical sectors.

Nano-Sieve–Enabled On-Chip Concentration and Multiplexed Detection of Raman-Dye–Labeled Nanocubes To address persistent challenges in molecular detection-particularly signal variability, low analyte abundance, and poor spectral reproducibility-a portable bead-stacked nano-sieve platform was engineered to enable robust on-chip Raman signal amplification using silver nanocubes (AgNCs) functionalized with Raman-active thiolated ligands. The microdevice integrates deformable elastomeric channels with magnetic bead stacking to immobilize and concentrate AgNCs within confined nanoscopic junctions, thereby generating densely packed plasmonic hot-spot architectures that markedly enhance Surface-Enhanced Raman Scattering (SERS) efficiency. Time-resolved measurements revealed substantial increases in Raman intensity for both 4-mercaptobenzoic acid (4-MBA) and 4-aminothiophenol (4-ATP), outperforming corresponding off-chip assays and maintaining stable enhancement factors over a four-hour operational window. Furthermore, the platform successfully demonstrated multiplexed sensing capability: mixed-analyte experiments containing 4-MBA, 4-ATP, and cysteamine produced clearly distinguishable spectral fingerprints, even under serial dilution and dynamically pulsed sample delivery. Collectively, these results establish the bead-stacked nano-sieve as a versatile, label-free, and scalable diagnostic architecture capable of achieving high sensitivity and spectral fidelity under continuous-flow conditions. Our technology holds significant promise for real-time, non-invasive molecular surveillance, point-of-care diagnostics, and early disease monitoring in resource-limited or field-deployable settings.

Thermal Stabilization Activities of Metal Oxide γ-Irradiated Styrene–Isoprene–Styrene Nanocomposites This study provides insights into the stabilization effects of certain oxides (CeO2, Cr2O3, Cd2O3, In2O3, MnO2, MgO, Nd2O3, and Pr2O3) in styrene–isoprene–styrene triblock copolymers with respect to neat materials. This study was performed via chemiluminescence (CL), which allowed for the determination of the main parameters characterizing the interphase coexistence: the oxidation induction times, oxidation rates, and onset oxidation temperatures. The improvement in the thermal performances of the pristine and γ-ray-processed samples at a moderate dose was highlighted differently due to the electronic interactions on the particle surface. While the non-isothermal CL measurements pointed to a weaker evolution of oxidation in the studied composites at a higher temperature range over 160 °C, the isothermal CL determinations revealed a delayed start of oxidation, slower oxidation rates, and greater activation energies in the nanocomposite aging patterns. The different individual behaviors of the investigated formulations were ascribed to the dissimilar electronic interactions between the particles and the surrounding matrix, where the oxidation initiators were formed by the molecular fragmentation of the polymer macromolecules. The kinetic features illustrate the influence of the peculiarities due to the electronic interactions. The higher resistance shown by the irradiated samples compared with the non-processed compositions demonstrates the stabilization efficiency of the fillers studied.

Biodegradability and biocompatibility are the advantages of PLA in DDS and other biomedical applications. Drug loading capacity, controlled drug release, and physical and mechanical properties are some critical requirements of materials for DDS. Additionally, the biological interactions of PLA, including its enzymatic hydrolysis, degradation into lactic acid, and subsequent metabolism through natural pathways, are essential for ensuring safe and efficient drug delivery. PLA‐based materials have the capabilities to be developed into various advanced materials to overcome their limitations in physical and mechanical properties, such as PLA nanocomposites, PLA‐copolymers, and stereocomplex PLA. Meanwhile, the hydrophobic character of PLA‐based materials is a main challenge in drug delivery applications. This review highlights recent advances in PLA‐based materials for DDS, focusing on material development, structure modification, and applications. Moreover, this review addresses the molecular modification and its relationship to tunable properties as potential next‐generation bio‐based polymeric materials for DDS.

Mechanical Behavior of Bioinspired Nanocomposites for Orthopedic Applications The application of bioinspired nanocomposites in orthopedic implants marks a significant innovation in biomedical engineering, aimed at overcoming long-standing limitations of conventional implant materials. Traditional implants frequently suffer from poor osseointegration, mechanical mismatch with bone, and vulnerability to infection. Bioinspired nanocomposites, modeled after the hierarchical structures found in natural tissues such as bone and nacre, offer the potential to enhance mechanical performance, biological compatibility, and implant functionality. This study reviews and synthesizes current advancements in the design, fabrication, and functionalization of bioinspired nanocomposite materials for orthopedic use. Emphasis is placed on the integration of nanocrystalline hydroxyapatite (nHA), carbon nanotubes (CNTs), titanium dioxide (TiO2) nanotubes, and other nanostructured coatings that mimic the extracellular matrix. Methods include comparative evaluations of mechanical properties, surface modifications for biocompatibility, and analyses of antibacterial efficacy through nano-topographical features. Bioinspired nanocomposites have been shown to improve osteoblast adhesion, proliferation, and differentiation, thereby enhancing osseointegration. Nanostructured coatings such as TiO2 nanotubes increase surface hydrophilicity and corrosion resistance, supporting long-term implant stability. Mechanically, these composites offer high stiffness, superior wear resistance, and improved strength-to-weight ratios. Biomimetic combinations of hydroxyapatite, zirconia, and biopolymers have demonstrated effective load transfer and reduced stress shielding. Additionally, antibacterial functionality has been achieved via nanostructured surfaces that deter bacterial adhesion while remaining cytocompatible with host tissues. The integration of bioinspired nanocomposites into orthopedic implants provides a multifunctional platform for enhancing clinical outcomes. These materials not only replicate the mechanical and biological properties of native bone but also introduce new capabilities such as infection resistance and stimuli-responsive behavior. Despite these advancements, challenges including manufacturing scalability, long-term durability, and regulatory compliance remain. Continued interdisciplinary research is essential for translating these innovations from laboratory to clinical practice.

Determination of Magnetic Anisotropy Tensors in Actinide Complexes Using Torque Magnetometry: A U(IV) Case Study In this study, we employed cantilever torque magnetometry to probe the magnetic anisotropy of a single crystal of U(DOTA)(H<sub>2</sub>O) (DOTA = 1,4,7,10-tetraazacyclododecane-1,4,7,10-tetraacetic acid), representing, to the best of our knowledge, the first application of this technique to an actinide-based molecular system. Combining cantilever torque magnetometry data with <i>ab initio</i> calculations allowed us to determine the magnetic anisotropy tensor of the uranium center. The resulting parameters enabled direct comparison with the isoelectronic lanthanide complex previously reported in the literature as well as with <i>ab initio</i> predictions for the theoretical Es<sup>4+</sup> isostructural analogue. We find that the magnetic anisotropy axes of <b>U(DOTA)(H<sub>2</sub>O)</b> (5<i>f</i><sup>2</sup>) closely align with those of the Pr<sup>3+</sup> (4<i>f</i><sup>2</sup>) and Dy<sup>3+</sup> (4<i>f</i><sup>9</sup>) analogues and with those predicted for <b>Es(DOTA)(H<sub>2</sub>O)</b> (5<i>f</i><sup>9</sup>). The combination of CTM and electronic structure calculations was essential to describe the weakly paramagnetic, EPR-silent, non-Kramers ground state of <b>U(DOTA)(H<sub>2</sub>O)</b>, despite the added complexity of four noncollinear molecules in the unit cell. Overall, these results demonstrate that cantilever torque magnetometry provides a powerful route to characterize the magnetic anisotropy of actinide complexes and offers a valuable experimental benchmark for validating computational approaches to 5f-element magnetism.
