Potassium solubilizing bacteria (KSB): Framework, stimulation of plant growth and future outlook: A review Potassium (K) is an essential macronutrient required for the fundamental growth and physiological development of all plants and animals. It is absorbed by plant roots and circulates throughout the organism as the cation K+. Although global soil reserves of potassium are typically high, the vast majority exists as insoluble minerals, meaning plants can only access a very small fraction of this total. This limitation has made modern agriculture heavily dependent on expensive synthetic fertilizers, which can degrade soil health over time. Potassium-solubilizing bacteria (KSB) offer a powerful biological solution by converting these inaccessible mineral forms into usable nutrients. Diverse bacteria, including Acidothiobacillus ferrooxidans, Paenibacillus spp., and various Bacillus species, have demonstrated the ability to dissolve silicate minerals such as biotite, feldspar, and mica. These microbes utilize a suite of biological processes including the secretion of organic and inorganic acids, acidolysis, polysaccharides, chelation, and exchange processes to release K into the soil solution. Utilizing KSB in integrated nutrient management not only boosts soil K availability but also promotes sustainable farming by reducing the reliance on chemical inputs. This review explores the framework of KSB, the specific biochemical pathways they use to solubilize K, and their multi-functional role in promoting plant development and crop yield. By addressing current challenges and outlining future research directions, this article underscores the importance of KSB as a cornerstone for sustainable global food security.

Predictive modeling of conductivity for carbon black nanocomposites: influence of filler features, interfacial effects and network portion The conductivity of carbon black samples depends on more than one or two obvious variables; it arises from a complex interaction of structural and surface factors acting in concert. Considering these interdependencies in a model is essential for designing materials that achieve reliable performance. In this study, we developed a theoretical framework that integrates the filler geometry, interphase thickness, tunneling resistance, tunneling distance, tunneling diameter, percolation threshold, and intrinsic conductivity of the filler. Rather than considering these parameters in isolation, the model allows them to interact, and its predictions are validated using experimental datasets. When the carbon black radius drops to 10 nm and the networked fraction of nanoparticles is 1, the conductivity of the composite increases to 1 S/m. As the particle radius increases or the fraction of networks decreases, the conductivity of the system decreases sharply and, in some cases, returns to the insulating state. The results further show that the composite conductivity is strongly governed by the polymer tunneling resistivity (p) and the interphase conductivity (σint). The lowest σint (< 200 S/m) produces an insulated system, while the composite conductivity maximizes to 3 S/m at p = 10 Ω.m and σint = 8000 S/m. Accordingly, more interphase conduction and less polymer tunnel resistivity are desirable to improve the conductivity of samples.

A La Plata Journey through Frozen Molecules: Matrix Isolation Spectroscopy Studies Matrix-isolation spectroscopy is a powerful and versatile technique in physical and analytical chemistry, enabling the detailed study of highly reactive and transient species under cryogenically stabilized conditions. By trapping molecules within an inert, rigid solid matrix—typically argon, nitrogen, or krypton at temperatures as low as a few Kelvin—this method effectively quenches thermal energy, suppressing diffusion and preventing chemical decay. This review highlights the application of this foundational technique in La Plata to explore multifaceted research centred on the generation, isolation, and characterization of novel molecular entities, elucidating their fundamental properties, reaction mechanisms, and reactivity. We present examples spanning the isolation of novel compounds, detailed conformational studies, the formation and analysis of molecular complexes, and the elucidation of photochemical mechanisms. The synergy between matrix-isolation FTIR spectroscopy and computational chemistry is emphasised as a basis for validating experimental findings and advancing molecular-level understanding.

Автоматизація проєктування композиційних електромагнітних екранів заданої ефективності Relevance. Shielding is the most effective means of improving electromagnetic safety for people and electromagnetic compatibility for electronic equipment. Only composite materials can control the protective properties (ratio of reflection, absorption and transmission coefficients) of electromagnetic waves. However, designing materials with the required protective properties is complex and requires large amounts of calculations. This makes it expedient to automate these processes by creating application software. The aim of this work is to automate the design processes of composite materials with controllable protective properties. Research results. Mathematical functions are provided to determine the effectiveness of electromagnetic radiation shielding by reflection and absorption of electromagnetic waves. It is shown that it is advisable to use fundamental relations of electrodynamics of continuous media to automate the design processes of composite protective materials. A list of theoretical and experimental data necessary for the design of protective materials is determined. Applied software has been developed that allows obtaining data on the effectiveness of electromagnetic radiation shielding by reflection and absorption of electromagnetic waves depending on the electrophysical parameters of the composite components and the volume content of the electrically conductive filler in the dielectric matrix. Using the example of a silicate material with a granulated copper filler, dependencies of the effectiveness of shielding ultra-high frequency electromagnetic radiation on the filler content were obtained. A comparison of the obtained data with the experiment shows their acceptable convergence. To accelerate the design of protective materials, a generalised function of the dependence of the electrical conductivity of the composite on the filler content was obtained. This allows reducing the amount of experimental work to obtain the initial data. Conclusions. The creation of application software for automating the design processes of composite materials allows optimising the effectiveness of protective materials by selecting the most acceptable components and the content of electrically conductive material in the dielectric matrix.

Nitrochalcones: Pharmacological Activities and Therapeutic Potential Chalcones are compounds containing an α,β-unsaturated carbonyl group that have been studied due to their structural simplicity, ease of synthesis, and broad spectrum of biological activities. Within this family, nitrochalcones have gained relevance due to the influence of the nitro group (-NO<sub>2</sub>) on the modulation of their electronic properties, chemical reactivity, and pharmacological behavior. This review presents a critical analysis of advances in the biological activities and possible mechanisms of action of nitrochalcones and their derivatives, with an emphasis on their structure-activity relationships and therapeutic potential. The available evidence shows that nitrochalcones and their derivatives act as multitarget molecules, capable of intervening in key biological processes such as oxidative stress, mitochondrial dysfunction, inflammation, and cell signaling pathways associated with proliferation and apoptosis. Several studies report anticancer, anti-inflammatory, antiparasitic, antimicrobial, antifungal, and cardiovascular activities, often with favorable selectivity toward pathological cells over healthy cells.

Waste utilization and optimization of calamansi peels: a formulation study on biodegradable microbeads One environmental challenge posed by agricultural waste in the Philippines can be mitigated by converting fruit peel waste into valuable cellulose-derived microbeads. Utilizing the ionic gelation technique, this study introduces a sustainable, “waste-to-value” innovation designed to replace synthetic microplastics in the cosmetic industry. The resulting microbeads are characterized by a yellowish-green, spherical morphology with a standardized particle size of 850 micrometers, well within the functional limit for exfoliants, and an excellent flowability rating indicated by a 26.55° angle of repose. When incorporated into formulations, the microbeads maintained high structural stability; the resulting hand sanitizer had a pH of 3.55, while the facial gel exfoliant had a pH of 7.6, demonstrating excellent homogeneity and foam stability. By successfully validating these bio-based alternatives, the study highlights a circular-economy approach that mitigates food-processing waste while providing eco-friendly, high-performance materials for the global personal care sector.

Optimization of bio-based cellulose-phosphate hydrogel production from rice husk waste using the Taguchi method This work reports the development and statistical optimization of a fully Bio-based absorbent hydrogel synthesized from rice husk–derived cellulose via phosphoric acid crosslinking. Cellulose was extracted through sequential chemical treatments and subsequently converted into a phosphate-crosslinked hydrogel using a controlled synthesis process. A Taguchi L16 (4⁵) orthogonal array was employed to optimize four key synthesis parameters: cellulose content, reaction time, heating temperature, and phosphoric acid volume. Hydrogel structure and morphology were characterized using Fourier Transform Infrared Spectroscopy (FTIR) and Scanning Electron Microscopy (SEM). FTIR results confirmed the formation of phosphate ester linkages, indicating successful crosslinking, while SEM observations revealed a porous and interconnected network structure favorable for water absorption. The optimized hydrogel formulation achieved a maximum swelling ratio of 91.25 g/g, demonstrating effective absorbent performance despite the absence of synthetic monomers or grafting agents. These findings indicate that rice husk waste can be efficiently valorized into an environmentally benign absorbent material through a simple and statistically guided synthesis route, supporting sustainable hydrogel development and agricultural waste utilization.

Production and Characterisation of Polyhydroxyalkanoates from Cocoa Mucilage Using a Wild-Type &lt;em&gt;Priestia aryabhattai&lt;/em&gt; Strain The accumulation of petroleum-based plastics demands sustainable alternatives such as polyhydroxyalkanoates (PHAs), biodegradable polyesters synthesised by numerous prokaryotes. However, high feedstock costs limit their commercialisation. This study evaluated cocoa mucilage, an underutilised by-product of the Ecuadorian cacao sector, as a low-cost carbon source for PHA production by a wild-type strain isolated from cocoa fruit residues. Bacteria were recovered from cocoa mucilage and pod shell fractions, screened for PHA accumulation by Sudan Black B staining with UV–Vis spectrophotometric confirmation, and identified by 16S rRNA gene sequencing. A first report of a single PHA-positive isolate, designated as Priestia aryabhattai strain NBP01-UTN, was recovered from the cocoa shell surface. Fermentation conditions were optimised using response surface methodology with a central composite design evaluating temperature, pH and ammonium sulphate concentration. The fitted quadratic model was highly significant (R² = 0.978, p &amp;lt; 0.0001), indentifying that temperature and nitrogen limitation were the dominant factors. Optimal conditions (40 °C, pH 7.30, 0 g·L⁻¹ (NH₄)₂SO₄) yielded 0.496 g·L⁻¹ PHA at 24 h (productivity ≈ 20.7 mg·L⁻¹·h⁻¹). FTIR and DSC analyses provided converging evidence consistent with poly(3-hydroxybutyrate). These results demonstrate the feasibility of coupling a locally isolated wild-type strain with cocoa mucilage for bioplastic production within a circular bioeconomy framework.

FRACTIONAL MATHEMATICAL MODELLING OF THE CORROSION RATE OF ALUMINUM 5083 IN A MARITIME ENVIRONMENT Aluminum 5083 is one of the materials used for the construction of ship hulls due to its classification as a material with good corrosion resistance. Despite its high corrosion resistance, Aluminum 5083 remains susceptible to galvanic corrosion and pitting corrosion caused by marine environmental conditions. This study develops a mathematical model by adding chloride and passivation effects using fractional differential equations to describe the corrosion rate of Aluminum 5083. The model construction using a Fractional Differential Equation System (FDES) aims to capture memory effects to represent the complex corrosion dynamics accurately. Stability analysis of the fractional model shows that the system is locally asymptotically stable, with all eigenvalues satisfying the condition . Furthermore, a numerical solution approach using the PECE-PI method is employed to solve the model, demonstrating agreement between the simulation results and real-world corrosion phenomena. Involvement of different fractional orders α reveals an effect on the rates of increase and decrease in concentration for each variable. The smaller the value of fractional order α, the slower the concentration change process occurs.

Experimental Demonstration of Airborne Virtual Hyperbolic Metamaterials for Radar Signal Guiding The inherent diffraction of electromagnetic waves, such as shortwaves and microwaves, severely limits the effective signal transmission distance, thereby constraining the development of related applications like radar and communications. This work experimentally demonstrates the use of a virtual hyperbolic metamaterial (VHMM) realized via a plasma filament array induced in air by a femtosecond laser. We characterize the ability of this VHMM to control electromagnetic waves in the shortwave and microwave bands, particularly its guiding and collimating effects. By combining experimental measurements with effective medium theory, we confirm that under specific parameters, the principal diagonal components of the permittivity tensor for the plasma array exhibit opposite signs, manifesting typical hyperbolic dispersion characteristics which enable the guiding of electromagnetic waves. This research provides a feasible approach for utilizing lasers to create dynamically reconfigurable and non-physical structures in free space for manipulating long-wavelength electromagnetic radiation, demonstrating potential for applications in areas such as radar, communications, and remote sensing.
