Nanonutraceuticals and their impact on non-communicable diseases: A review Noncommunicable diseases (NCDs) represent one of the most critical health concerns worldwide, being responsible for about 68% of all deaths annually, which equates to roughly 38 million people.In India, they contribute to nearly 60% of disease-related morbidity, affecting around 5.87 million individuals.Chronic ailments such as diabetes mellitus, cardiovascular disorders, cancers, endocrine and urogenital diseases, vascular complications, and respiratory illnesses account for the majority of these deaths, causing nearly 41 million fatalities each year, approximately seven out of every ten global deaths.Beyond mortality, NCDs impose severe socio-economic challenges through elevated healthcare costs, diminished productivity, and financial instability, particularly evident during infectious disease outbreaks like COVID-19.In response, the preventive and therapeutic potential of nanonutraceuticals, the bioactive compounds derived from medicinal plants, fruits, vegetables, and grains, incorporated into nanoscale delivery systems, has gained increasing scientific attention.Traditional nutraceuticals often face challenges such as poor water solubility, low chemical stability, and limited bioavailability, which restrict their clinical efficacy.Nanotechnology-based formulations offer a promising solution by enhancing the solubility, stability, absorption, and targeted delivery of these bioactives, thereby maximizing their biologica l effectiveness and therapeutic outcomes.This review summarizes the emerging importance of nanonutraceuticals in mitigating and managing non-communicable diseases, emphasizing their potential as complementary strategies alongside conventional medical interventions.

Modular and Vertically Integrated Microsupercapacitor Arrays Based on Laser‐Induced Graphene and Bimetallic Oxide Interfaces on Liquid Crystal Polymer Substrate We report a modular, vertically integrated microsupercapacitor (MSC) by developing laser‐induced graphene (LIG) and in situ grown bimetallic metal oxides on liquid crystal polymer substrates. Utilizing spatially confined photothermal synthesis with complementary Ru‐ and Mn‐based precursors, we induce synergistic oxidation reactions to form highly dispersed oxide nanophases within a 3D porous LIG matrix, overcoming the intrinsic capacitance limitations of pristine LIG. Optimized lasing parameters and stoichiometric control yield hierarchically structured electrodes with high electrical conductivity, mechanical resilience, and enhanced charge storage. A through‐via stacking strategy enables vertical MSC assembly with minimal footprint while maintaining sufficient areal energy and power densities. Integration with photovoltaic cells and converter circuits supports rapid charging and stable energy output, even under fluctuating light conditions. Demonstrations across wireless IoT modules, GPS tracker, and pressure‐activated µ‐LED validate device‐level viability for autonomous systems. This work establishes a scalable, current collector‐free, and structurally conformable MSC architecture, offering a promising pathway for next‐generation integrated energy storage in flexible electronics.

Synthesis and Transformations of Bioactive Scaffolds via Modified Mannich and <i>aza</i>‐Friedel–Crafts Reactions This account summarizes the synthesis of bifunctional glycine-type precursors substituted with 2- and 1-naphthol. The stabilization of precursors via partially aromatic ortho-quinone methide intermediate is tested with different cyclic imines in [4 + 2] cycloaddition. 8-Hydroxyquinoline is a biologically active moiety considered as a formal 1-naphthol analog, hence the behavior of the scaffold in Mannich reaction is examined. The possibility of transformation of glycine derivatives substituted with 2- and 1-naphthol as well as the formed Mannich base consisting 5-chloro-8-hydroxyquinoline skeleton to give diarylmethane derivatives with indole and 7-azaindole are studied. A series of cyclic amines coupled with indole and azaindole derivatives has been systematically designed and their biological examination is achieved. To have a preliminary overview about the structure-activity relationship, the antibacterial and anticancer activity of synthesized compounds by preliminary biological screening systems is tested.

Heavy Prussian Blue Analog with Magnetic Ordering above 400 K Molecule-based magnets hold promise for a variety of applications in information technologies owing to their chemical tunability. This feature can facilitate the integration of desired magnetic properties alongside additional functionalities within a single material. Although numerous cyanido-bridged assemblies are identified as multifunctional materials at cryogenic temperatures, achieving analogous behavior at room temperature remains a challenge. This study reports a cyanido-bridged compound, which shows ferrimagnetic ordering with a critical temperature exceeding 400 K. This breakthrough is achieved through the mechanochemical synthesis of vanadium(II)-hexacyanomolybdate(III) Prussian Blue Analog (PBA) under anhydrous conditions. The ferrimagnetic order is evidenced by SQUID (SQUID = superconducting quantum interference device) magnetometry and X-ray Magnetic Circular Dichroism (XMCD) spectroscopy. Both techniques unambiguously confirm the antiparallel alignment of vanadium and molybdenum magnetic moments. As a result, hexacyanomolybdate(III) is experimentally established as a viable precursor for the preparation of a new generation of high-temperature molecule-based magnets and multifunctional materials.

Nanoparticle‐Mediated Targeted Protein Degradation: An Emerging Therapeutics Technology Abstract Targeted protein degradation (TPD) has emerged as a transformative therapeutic strategy for eliminating disease‐associated proteins, with relevance across disorders ranging from cancer to neurodegeneration. Since its inception nearly two decades ago, TPD has attracted strong academic and commercial interest, with multiple candidates advancing into clinical trials. Despite this progress, the field faces persistent challenges, including limited solubility, poor cellular uptake, and unpredictable structure–activity relationship of small‐molecule degraders, which complicate rational design. To address these limitations, alternative platforms such as nanoparticle‐mediated protein degraders (NanoPDs) have gained attention. First reported 17 years ago, NanoPDs harness a diverse array of materials, degradation mechanisms, and linker chemistries to achieve protein clearance through novel pathways. Although promising, their clinical translation remains constrained by barriers such as lysosomal entrapment, protein corona formation, and biocompatibility concerns. In this review, we present a comprehensive overview of the current landscape of nanoparticle‐mediated TPD. We emphasize the design principles underlying nano–bio interfaces and explore the role of proximity‐induced biology as a mechanism for orchestrating protein interactions. Finally, we highlight critical challenges and key questions that must be addressed to fully realize the therapeutic potential of NanoPDs.

Recent Advances in the Rhodium‐Catalyzed C─H Bond Functionalization Reactions of 2‐phenylpyridines Abstract Transition metal catalyzed C─H activation is a dynamic synthetic route for coupling reactions in the field of chemistry, which has been developed over the last 20 years. The C─H activation approach for achieving C─C bond cross‐coupling reactions avoids all elements of pre‐functionalized substrates and lengthy synthetic routes. Pyridine‐derived moieties are indispensable in directed C─H bond activation by selective direction of the transition metal catalyst to bind C─H bonds in the phenyl ring. This review focuses on the rhodium(III)‐catalyzed direct functionalization of C─H bonds under oxidative conditions, enabling the formation of C─C, C─N, and C─O bonds of 2‐phenylpyridines to functionalized products with an emphasis on reports from 2009. The efficient creation of C─E bonds (where E═C, N, S, or O) makes Rh(III) catalysis an appealing, step‐efficient method for producing value‐added molecules from readily available starting materials. Focus is given to the significant regioselectivity and functional group tolerance of each reaction mechanism, along with a brief discussion of a few mechanistic pathways. Also demonstrates considerable scientific progress and greater advances, particularly in developing functionalized systems via transition metal‐catalyzed C─H activation with practical applications in the pharmaceutical industries, agrochemical industry, and drug discovery.

Investigating The Redox Properties Of Photoredox Catalysts And Organic Compounds Through Quantum Chemistry This dissertation explores the redox behavior of organic and organometallic systems using density functional theory (DFT), focusing on electron transfer mechanisms and structur –property relationships. The first study investigates the two-electron reduction of bianthrone isomers, revealing a potential-inverted ECE mechanism driven by isomerization and electronic destabilization. The second study examines ruthenium photoredox catalysts, showing that ligand fusion positions significantly affect redox potentials due to backbone dearomatization, while p extension has minimal impact. Together, these findings provide insight into redox tuning strategies and support the rational design of advanced catalysts and electroactive materials.

Antifungal and photocatalytic potentials of zinc oxide nanoparticles synthesized using various fruit peel aqueous extracts Banana (Musa spp), mango (Mangifera indica) and pineapple (Ananas comosus) peel aqueous extracts were employed to synthesize zinc oxide nanoparticles (ZnONPs), namely; ZnO-BPE, ZnO-MPE and ZnO-PPE, respectively. A reference sample, ZnO-ppt (without fruit peel extract) was also synthesized by simple precipitation. These were calcined at 500 °C and characterized using x-ray diffraction (XRD), Fourier transform infra-red spectroscopy (FT-IR), UV-visible spectroscopy (UV-VIS), Brunauer-Emmett-Teller (BET), Thermogravimetric analysis (TGA/DTG), scanning electron microscopy-electron dispersive x-ray (SEM-EDX) and Transmission electron microscopy (TEM) techniques. The XRD of the samples revealed a hexagonal wurtzite crystalline structure typical of ZnONPs, with the Debye Scherrer’s crystallite sizes ranging from 21 to 38 nm. FTIR spectra of the samples showed Zn-O vibration bands at ~ 521 cm−1 while the UV-vis showed a narrow band gap in the range of 2.41–2.85 eV, and good UV light absorption in all the samples. The SEM images showed significant differences in the morphology of the samples, including spherical-hexagonal shape for the ZnO-ppt sample, and flower-like shaped particles for the ZnO-MPE. Antifungal assay showed that all the samples are active against Trichosporon sp and Aspergillus niger isolates. Highest zones of inhibitions were obtained for the ZnO-MPE against Trichosporon sp., while the ZnO-PPE sample showed the lowest MIC of 62.5 µg/ml against Aspergillus niger. Photodegradation potential of the samples against 10 ppm methylene blue solution showed 73–91% degradation under UV-light irradiation. The best-performing photocatalyst, ZnO-MPE, sustained its efficiency over three regeneration cycles.

Bridging-induced densified MXene films with ultralow single-atom Pt loading for highly efficient hydrogen evolution Platinum (Pt)‐based materials have garnered significant attention due to their exceptional electrocatalytic performance and potential for advancing water splitting technology. However, reducing Pt usage simultaneously maintaining its high catalytic performance remains a critical challenge. Here, ultralow content (0.25 wt‰) of Pt single atoms (SAs) were successfully anchored onto Ti<sub>3-x</sub>C<sub>2</sub>T<em><sub>y</sub></em> MXene nanosheets, followed by the preparation of self-supported, densified MXene film electrocatalysts through a sequential bridging process involving hydrogen and covalent bonding (denoted as 0.25-HCM@Pt<sub>SA</sub>). The resulting 0.25–HCM@Pt<sub>SA</sub> film catalyst exhibits excellent hydrogen evolution reaction (HER) performance, showcasing a small overpotential of 48 mV at 10 mA cm<sup>−2</sup>, an ultrahigh mass activity of 28.93 A mg<sub>Pt</sub><sup>−1</sup>, and a large turnover frequency of 23.45 s<sup>−1</sup> at an overpotential of 100 mV. Furthermore, density functional theory calculations reveal that the anchoring Pt SAs on the densified MXene film reduces the binding energy and hybridization strength between H atoms and the support, contributing to rapid hydrogen adsorption−desorption kinetics and high HER activity. This work provides a promising and scalable strategy for designing 2D materials-based noble metal electrocatalysts with ultralow metal loading and high catalytic activity.

Nanomaterial-Mediated Alleviation of Abiotic Stress in Plants: Mechanisms and Applications Drought, salinity, heavy metal contamination and temperature fluctuations are increasingly constraining crop production. Conventional agronomic and chemical approaches alone often fail to ensure stable yields under these abiotic stresses. Nanomaterials are emerging as complementary tools for improving stress tolerance and helping to stabilize yield because they can interact efficiently with key processes at the rhizosphere, at the leaf surface and within cells. Their high surface area, tunable surface chemistry and functionalization, and controlled-release properties make them suitable for root application, foliar spraying, and seed treatment. These features enable low-dose, efficient, and targeted delivery. This review delineates five mechanistic dimensions: restoring redox homeostasis; enhancing nutrient uptake and maintaining ion balance; modulating signaling factors and hormone levels; influencing gene expression; and improving structural and physiological traits at the root and chloroplast levels. Based on case studies under salinity, drought, and heavy metal conditions, we summarize material- and route-dependent differences in efficacy and define dose boundaries. Moreover, the current limitations arising from limited field evidence and nonuniform evaluation standards are also highlighted. Accordingly, we outline key considerations for material design and application assessment, underscoring the value of this review in integrating mechanisms and guiding the practical translation of nanomaterials for stress alleviation in plants.

Enhanced physical properties and antimicrobial activity of PEG-4000 capping on CoxCu1-xFe2O4 nanoparticles for technological applications: Synthesis and characterization Abstract This research presents an in depth study of the electrical and antibacterial activity of Co x Cu 1-x Fe 2 O 4 and their polymer nanocomposites. The citrate precursor auto-combustion method was successfully used to synthesize the nanostructured Co x Cu 1-x Fe 2 O 4 . To investigate the impact of PEG on the physical characteristics, polymer-blended ferrite nanoparticles were produced using PEG-4000 as a capping agent. X-ray diffraction analysis of Co x Cu 1-x Fe 2 O 4 verified their cubic spinel structure, and Rietveld analysis was used to further refine the results using FULLPROF software. The lattice constant ( a ) increases, while the crystal size decreases by increasing Co 2+ concentration. According to the measured elastic properties, PEG in PEG/Co x Cu 1-x Fe 2 O 4 nanocomposites made it softer and more durable. CuFe 2 O 4 was found to have maximum conductivity and dielectric loss but lower dielectric permittivity. PEG enhances the dielectric permittivity of some Co x Cu 1-x Fe 2 O 4 . The Nyquist plots were fitted by the ZSimpWin program, and the equivalent circuit demonstrates that the electrode, grain, and grain boundaries contributed to the polarization process. Co x Cu 1-x Fe 2 O 4 samples are suitable for high-frequency applications due to their low dielectric loss. Thermal conductivity tests reveal that CuFe 2 O 4 has the highest value among the ferrite samples. The thermal conductivity of the composites exceeds that of pure ferrites. The nanoparticles and their composites exhibited antimicrobial activity against both gram-negative bacteria (E. coli) and gram-positive bacteria (Staph. Aureus). These intriguing findings suggest that these materials are excellent candidates for technological and therapeutic applications.
