Advances in NP shapes and their applications in cancer therapy Cancer is a major global cause of death, yet traditional treatments such as surgery, chemotherapy, and radiotherapy have inherent limitations. Nanoparticles (NPs) are rapidly emerging as drug delivery systems for cancer treatments, offering promising advancements to overcome associated challenges and enhance therapies. Innovation in nanoparticle shapes is crucial in nanotechnology research worldwide. Studies indicate that the shape of nanoparticles can affect their tumor-targeting efficiency and blood circulation time. For example, the tumor accumulation of nanorods is reported to be 3-5-times higher than that of nanospheres, while the blood circulation time of nanodisks can be extended by 2-3-times compared to nanospheres. In this review, we first introduce different shapes of nanoparticles, illustrate their fabrication processes, and present their applications. Then, we examine recent research on NP shapes for various cancer treatments, discussing their challenges, perspectives, and potential impact on oncology and offering a deeper understanding.

Interplay Between Exfoliation and Functionalization Strategies for Group VI Layered Transition Metal Dichalcogenide Dispersions The ability to efficiently tailor the surface properties of layered transition metal dichalcogenide (LTMD) dispersions is critical for optimizing performance and enabling scalable manufacturing techniques, such as spray coating and inkjet printing, for optoelectronic, energy storage, and sensing applications. Group VI LTMDs, owing to their unique properties in the monolayer architecture, offer exceptional potential; however, the properties of exfoliated dispersions are strongly dependent on the specific solution-processing techniques employed. These techniques determine the choice of subsequent surface functionalization strategies and, consequently, the characteristics of the resulting functionalized hybrids. Furthermore, the inherent heterogeneity of solution-processed dispersions-manifested, among other factors, in broad distributions of flake thickness and lateral size-remains a significant challenge and strongly influences the behavior of hybridized materials. As a result, exfoliation-method-dependent properties and dispersion heterogeneity introduce substantial complexity in the selection of appropriate surface-tailoring strategies, characterization methodologies, and data interpretation. To address these challenges, we systematically classify exfoliated Group VI LTMD dispersions according to their exfoliation methods and highlight recent findings that challenge previously accepted assumptions in the field. Finally, we provide perspectives on surface functionalization approaches for Group VI LTMDs and discuss key limitations associated with the characterization of these newly hybridized materials.

Enhancing Electromagnetic Wave Absorption in 3D-Printed Concrete with Superabsorbent Polymers for High Performance The widespread application of concrete with specific functions has become indispensable in modern technology. However, the persistent issue of electromagnetic pollution poses a serious hazard to human health, electronic equipment, and military operations. Although various conventional electromagnetic absorbing materials have been incorporated, the achievable EMW-absorption performance is still restricted, with only a narrow effective absorption bandwidth. This study investigates the application of advanced 3D-printing technology to produce concrete with enhanced EMW-absorption properties with the incorporation of SAP (super-absorbent polymers). To achieve this, concrete samples with three SAP occupying the concrete volumes (0 vol.%, 20 vol.%, and 40 vol.%) and three methods (pretreatment-addition) were examined to provide an in-depth analysis of the properties and microstructures. The study reveals superior electromagnetic absorption in concrete enhanced with SAP compared to the untreated counterpart. Specifically, samples subjected to 40 vol.% Dry Treatment SAP exhibited exceptional performance, achieving 98.77% absorption at 7.53 GHz frequency with a peak reflectance of −19.12 dB, outperforming unmodified absorbing resin concrete by 25.44%. Moreover, microscopic analysis revealed irregular void distribution within the concrete, while the 3D-printing and -mixing processes led to SAP particle fractures, forming a complex 3D structure, thereby enhancing EMW-absorption performance. Ultimately, by selecting appropriate SAP pre-treatment and mixing methods based on the specific frequency range, this study provides crucial references and practical guidance for the application of EMW-absorbing concrete in military and technological contexts.

Zinc molybdenum thiovanadate nanoparticles: synthesis, characterization, and antibacterial activity Infection control is a key point for maintaining and developing the healthcare sector. Nanosized metal derivatives have attracted significant interest for preventing infections caused by various bacteria and fungi. This study reports the synthesis of new sulfide nanoparticles containing bioactive Zn, Mo, and V in one structure. Powder X-ray diffraction (PXRD) analysis was used to determine the structure, phase purity, and crystallite size of the ZnMoVS<sub>4</sub> nanoparticles (NPs). The results reveal the presence of only one phase corresponding to a cubic close-packed spinel structure in the <i>F</i>4̄3<i>m</i> (216) space group. The calculated crystallite (grain) size is 16.86 nm, which falls within the nanoparticle size range. High-resolution transmission electron microscopy (HR-TEM) was utilized to verify the nanoscale size and crystallinity of the NPs and to examine their morphology. High-angle annular dark-field scanning transmission electron microscopy (HAADF-STEM) was used to perform elemental mapping and confirm the chemical composition of the prepared NPs. X-ray photoelectron spectroscopy (XPS) analysis was performed to confirm the presence and oxidation states of all the introduced elements. These results are consistent with the proposed chemical formula of ZnMoVS<sub>4</sub> for the prepared NPs. The bioactivity of the prepared NPs was studied using three waterborne Gram-negative bacteria: <i>Escherichia coli</i>, <i>Salmonella choleraesuis</i>, and <i>Shigella flexneri</i>. The results revealed the significant effect of the ZnMoVS<sub>4</sub> NPs on the studied bacteria. However, <i>Escherichia coli</i> showed greater suppression upon treatment than <i>Salmonella choleraesuis</i> and <i>Shigella flexneri</i>. Hence, the introduced NPs are promising antimicrobial candidates for water treatment to prevent waterborne bacterial diseases.

Green synthesis of bio-compatible carboxylate-functionalized carbon layers of 4 to 26 nm thickness on gold plasmonic nanoparticles Polycrystalline spherical plasmonic gold nanoparticles (GNPs) were coated with carboxylate-functionalized carbon layers with unprecedented thinness down to 4 nm, tunable between 4 and 26 nm, <i>via</i> a hydrothermal approach using glucose, fructose or sucrose as carbon sources. This synthetic approach allows for the formation of conformally coated GNPs with well-controlled carbon-layer thicknesses as a function of initial carbon source concentration. These carbon coated GNPs exhibit plasmon resonance at ∼545 nm and have an increased absorbance at 400 nm, which is found to correlate linearly with the thickness of the carbon layer with a squared Pearson correlation coefficient of 0.94. The coated GNPs are shown to be bio-compatible through incubation with SH-SY5Y cells with varying carbon coating thicknesses, without changes in cellular morphology and exhibiting increased proliferation with no notable differences when compared with the control or citrate capped GNPs, over 48 hours.

Synthetic Carbon Nanobionic Interfaces for Enhancement of Plant Photosynthetic Efficiency Boosting the photosynthetic efficiency remains a critical challenge for sustainable crop productivity. In this study, the design, synthesis, and functional evaluation of two carbon-based nanomaterials are reported: a fluorescent carbon nanoassembly (Compound 1) derived from citric acid and urea, and a cerium-incorporated variant (Compound 2) incorporating redox-active cerium oxide domains. Comprehensive characterization confirmed the formation of nanostructured materials with tunable optical properties, surface functionalities, and crystalline features. Both compounds exhibited strong UV-A absorbance and blue photoluminescence, with Compound 2 showing enhanced emission and additional red-shifted features due to cerium integration. Greenhouse trials usingRaphanus sativus as a model plant revealed significant improvements in biomass, pigment concentration, and ascorbic acid levels in the treated plants. Confocal microscopy and inductively coupled plasma mass spectrometry confirmed nanoparticle uptake and translocation, while flow cytometry revealed altered chloroplast fluorescence, supporting functional interaction at the organelle level. Together, these results establish carbon-based nanobionics as a promising platform for photonic enhancement of photosynthesis, offering new opportunities for advanced bioagricultural applications.

Effect of primary-secondary synergistic system on the aging resistance of <i>Salix psammophila</i> /polylactic acid composites To enhance the hydrothermal aging resistance of <i>Salix psammophila</i> wood flour/polylactic acid (PLA) composites, a primary-secondary synergistic anti-aging system was constructed using antioxidant 1010 as the primary antioxidant and distearyl thiodipropionate (DSTP) as the auxiliary antioxidant, with maleic anhydride as an interfacial compatibilizer. The composites were fabricated by hot-pressing, and the effects of the synergistic system on mechanical performance and hydrothermal aging behavior were investigated. Static mechanical results showed that the 1010/DSTP system enhanced the initial mechanical properties and effectively mitigated mechanical degradation after aging. After hydrothermal aging (60 °C, 96 h), the synergistically modified composite (WPC-1/D) retained 47.38% of its flexural strength, representing a 56.54% increase compared to the aged, unmodified control. Stress-strain behavior indicated improved deformation coordination and delayed damage evolution, suggesting enhanced interfacial stability under hydrothermal conditions. Dynamic mechanical analysis further confirmed the synergistic effect, as WPC-1/D exhibited a high storage modulus of 1295.43 MPa in the glassy region after aging, together with increased loss modulus and loss factor peaks, reflecting restricted molecular chain mobility and enhanced energy dissipation. A static-dynamic mechanical correlation model was established to quantitatively describe the relationship between macroscopic mechanical degradation and viscoelastic response during hydrothermal aging. Microscopic observations revealed a multi-scale progressive aging process from damage initiation to damage penetration, clarifying the aging damage pathways. Chemical analysis showed that the O-H absorption peak of WPC-1/D shifted most slowly from 3332 cm<sup>-1</sup> to 3422 cm<sup>-1</sup>, the ester C[double bond, length as m-dash]O group exhibited only slight displacement, and no new CH<sub>3</sub>-related absorption peaks emerged; meanwhile, the carbon content increased from 73.88% to 80.03% and the oxygen content decreased from 25.92% to 18.80%, indicating suppressed hydrolysis-oxidation degradation. This study elucidates the anti-aging mechanism of the primary-secondary synergistic system and provides empirical insights and experimental evidence for improving the durability of fully biodegradable composites.

Electrochemical Access to N-Aryliminium Ion Electrophiles from N-Aryl Amino Acids N-aryl hemiaminals are versatile synthetic intermediates that can serve as placeholders for N-aryliminium ions. We report the non-Kolbe anodic decarboxylation of N-arylamino acids for efficient synthesis of an array of N-aryl hemiaminals. The reported electrochemical method is convenient and air-tolerant with a simple workup, user-friendly controls, and employs inexpensive electrode materials. We demonstrate the utility of these intermediates in traditional Povarov cyclizations under the action of Lewis acid affording 4-phenyltetrahydroquinolines (up to 70% yield over two steps). We also demonstrate the direct electrochemical synthesis of polycyclic frameworks relevant to several bioactive natural products from simple N-arylamino acid starting materials.

Scalable Chemoenzymatic Iodination of Waste‐Derived Phenolic Acids Using Pyranose 2‐Oxidase for In Situ H <sub>2</sub> O <sub>2</sub> Generation Sustainable valorization of biomass-derived aromatics is essential for green chemical manufacturing. Palm oil mill effluent (POME), a major agro-industrial wastewater, contains phenolic acids such as p-hydroxybenzoic acid (p-HBA) that inhibit anaerobic digestion but represent valuable chemical feedstocks. Here, we demonstrate a scalable chemoenzymatic platform for selective iodination of p-HBA, vanillic acid (VA), and ferulic acid (FA) using pyranose 2-oxidase (P2O) to generate hydrogen peroxide in situ under mild aqueous conditions. Buffer screening revealed that tris(hydroxymethyl)aminomethane hydrochloride, 4-(2-hydroxyethyl)-1-piperazineethanesulfonic acid, and sodium phosphate best promoted monoodination of p-HBA, VA, and FA, respectively. Compared to direct H<sub>2</sub>O<sub>2</sub> addition, P2O-mediated oxidant supply improved selectivity for 3-iodo-p-HBA (3-IHBA) (15% vs. 21%), suppressed di-iodination, and prevented oxidative coupling of FA. Liter-scale reactions retained small-scale efficiency, achieving >99% conversion and 93% yield for VA, and 89% conversion with 88% yield for FA. Moreover, direct conversion of POME-derived p-HBA yielded 3-IHBA (19%), confirming compatibility with real wastewater matrices. This work establishes P2O-driven iodination as a mild, selective, and scalable route for synthesizing iodinated aromatics from waste-derived phenolics, providing a green alternative to conventional halogenation and advancing sustainable biorefinery development.

Recombinant Fibrinogen‐Gamma‐Chain as a Crosslinker of Thiol‐ene Hydrogels Hydrogels based on thiol-ene step-growth chemistry have gained increased attention due to their superior properties over the currently standard materials based on chain growth polymerization. In the thiol-ene reaction, a crosslinker with at least two thiol groups is necessary for network formation. Many currently used crosslinkers exhibit cytotoxic potential, are non-biodegradable, or involve toxic chemicals and relatively complicated procedures in their synthesis, thus hindering their broader application. As an alternative, the use of a protein (fibrinogen gamma chain, FGG) recombinantly expressed in Escherichia coli was investigated. The FGG is part of the multimeric fibrinogen involved in hemostasis. This protein complex is stabilized by disulfide crosslinking. This presence of cysteines in the sequence makes FGG a promising candidate as a thiol donor in thiol-ene reactions. It was shown for the first time, that a cysteine-containing protein expressed in E. coli was capable of forming hydrogels with norbornene functionalized gelatin. An increase in FGG concentration led to higher gel stiffness and a decrease in the swelling ratio. Furthermore, the material exhibited cell adhesive properties and biocompatibility. Overall, a proof-of-principle could be achieved, opening up the use of recombinant proteins without further modifications as crosslinkers in thiol-ene based hydrogels, providing a cost-effective, safe, and scalable material source.

Entropic phase separation in polymer--vitrimer melts Traditional plastics demand a choice between durability (thermosets) and reprocessability (thermoplastics). Vitrimers are a recent class of polymer network combining both these qualities. Their increased cost of production can be offset by mixing them with a traditional thermoplastic; however, phase separation in such blends can lead to inhomogenous materials. In this paper, we adapt an existing model for the free energy of dissociative polymer networks to their associative, vitrimeric counterpart. We test the accuracy of the model's predictions by comparing them with the results of novel molecular-dynamics simulations. We demonstrate that such melts can undergo phase separation even in the absence of energetic interactions between the components. We find furthermore that the phase diagram of the melts is qualitatively similar to that of dissociative systems, and that the critical degree of conversion for the onset of phase separation depends reciprocally on the number of function sites per vitrimer chain.

Perspective: twenty-five years of nanoscale thermal transport modeling Over the past twenty-five years, I have explored the application of molecular dynamics simulations and lattice dynamics calculations for determining phonon properties and thermal conductivity. Motivated by conversations with my group members and colleagues, I share insights about aspects of these methods that can be overlooked or misunderstood. For molecular dynamics, I focus on how to set up the simulations and apply the Green-Kubo method. For lattice dynamics, I outline the calculation workflow and highlight key decisions. I offer thoughts about the benefits of calculations and how they can be compared to experiments. I share highlights, mistakes, and missteps from my group’s work. I conclude with reflections on the past, present, and future of nanoscale thermal transport modeling.
