However, applying this encapsulation method, initially developed for CdSe-based QDs, to InP-based QDs results in a significant decrease in photoluminescence quantum yield (PLQY). To understand this discrepancy, we prepared three types of QDs (InP/(ZnSe)<sub>n</sub>/ZnS, with <i>n</i> = 4, 6, 8 monolayers) that emit in the green region and encapsulated them into silica particles (~ 30 nm in size, typically containing ~ 10 QDs per particle). Increasing the thickness of the intermediate ZnSe layer from 1.3 (4 monolayers) to 2.7 nm (8 monolayers) using the same core size (1.6 nm) effectively suppressed the decrease in PLQY after encapsulation. Quantum mechanical calculation revealed that compared to CdSe-based QDs, the excited electron in InP-based QDs tends to spread significantly due to the lighter effective electron mass and lower barrier height from the InP core to the ZnSe and ZnS shells. As the ZnSe layer thickness increases, the amount of spread electron reduces, thereby better maintaining the PLQY after encapsulation. The calculations further suggest that larger cores (> 2.2 nm) and thicker shells (> 2.5 nm) are preferable for achieving high PLQY after silica encapsulation. This knowledge serves as a guideline for developing ideal QDs with bright, robust, and non-toxic features as user-friendly phosphors.</p></div>","PeriodicalId":653,"journal":{"name":"Journal of Nanoparticle Research","volume":"27 3","pages":""},"PeriodicalIF":2.1,"publicationDate":"2025-03-12","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143594795","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"材料科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

It highlights the potential formation of anisotropic aggregates composed of multiple magnetite nanoparticles even in the absence of an external magnetic field. These aggregates, when combined with gold nanoparticles, can selectively bind to mechanoreceptors on the membranes of malignant cells employing aptamers. The aggregation process suppresses thermal fluctuations of the intrinsic magnetic moments of individual particles, thanks to the collective magnetic field generated by the resulting subaggregates. As a result, these nanoparticle aggregates demonstrate stabilization of their total magnetic moment driven by this cooperative behavior. The growth of aggregates of magnetic nanoparticles is accompanied by an increase in the total magnetic moment of the aggregates and the strength of the mechanical effect on cell mechanoreceptors. This enhanced interaction can contribute to the programmed death of malignant cells (apoptosis) in malignant cells when exposed to an alternating magnetic field.

This review critically assesses borophene’s potential, emphasizing its remarkable theoretical storage capacities for Li-ion and Na-ion batteries, underpinned by ultrafast ion-diffusion pathways with minimal energy-barriers and bandgap (9.43eV in zigzag-direction) (Duo et al. Coord Chem Rev 427: 213549, 2021). Advanced density functional theory simulations elucidate borophene’s structural stability, ion-transport mechanisms, and tunable electronic properties achieved through carrier doping, defect engineering, and strain modulation. The review highlights novel synthesis strategies, such as plasma ion-implantation on unconventional substrates like carbon cloth and silicon, mitigating existing fabrication bottlenecks. Experimental validations confirm borophene’s superior electrochemical performance, demonstrating exceptional electrocatalytic activity with low overpotentials for hydrogen evolution reactions and high specific capacitance in supercapacitors. Concomitantly, various approaches encompassing carrier-doping, external-strain, and defect formation that assist in tuning the features of borophene have been discussed briefly in this study. By integrating theoretical insights with experimental advancements, this study identifies critical research-gaps and presents critical discussions and roadmap for leveraging borophene’s anisotropic features in next-generation energy storage systems, advancing the frontier of 2D-materials for sustainable energy technologies.</p><h3>Graphical Abstract</h3>\u0000<div><figure><div><div><picture><source><img></source></picture></div></div></figure></div></div>","PeriodicalId":653,"journal":{"name":"Journal of Nanoparticle Research","volume":"27 3","pages":""},"PeriodicalIF":2.1,"publicationDate":"2025-03-04","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143533149","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"材料科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

We present the results of a theoretical model for the cohesive energy, melting temperature and Debye temperature of silver (Ag) and gold (Au) nanoparticles, developed and analyzed using computer simulations in MATLAB, and validated against experimental data and other theoretical predictions. The results indicate that nanoparticles have lower cohesive energies because of the surface atoms that dominate, resulting in lower melting and Debye temperatures with decreasing particle size. The cohesive energy of Ag nanoparticles decreases from ~ 285 kJ/mol in the bulk to ~ 230 kJ/mol at 5 nm, accompanied by a corresponding decrease in the melting temperature from 1235 K to ~ 700 K, Debye temperature from 230 K to ~ 100 K. The cohesive energy of Au nanoparticles lowers from ~ 368 kJ/mol for bulk to ~ 300 kJ/mol for 5 nm, and the melting temperature and Debye temperature drop from 1337 and 415K, respectively, to around ~ 600K and ~ 200K simultaneously. The experimentally observed and theoretically predicted size dependent trends in these properties are consistent with these trends showing that these properties are intertwined by the atomic bonding strength and vibrational dynamics. All three properties are higher for Au due to stronger metallic bonding.
