Here, we compared the dissolution kinetics and compositional changes at surfaces between citrate-stabilized amorphous calcium phosphate (ACPc) and crystalline hydroxyapatite nanoparticles (HANPs) when exposed to citric and acetic acid buffers, two organic acids commonly present in root exudates. A series of complementary orthogonal characterization techniques, including FTIR, Raman, and PXRD, were combined to elucidate the evolution of the Ca/P ratio, pH change, and recrystallization of calcium phosphate. We found that changes in pH and Ca/P ratio during dissolution in HANP and ACPc were largely due to differences in the formation of surface complexes between the acids and the intra-particle migration of protons (confirmed from H₂O/D₂O isotope exchange). A greenhouse pot trial experiment was performed using commercial lettuce to ground-truth how these characteristics influence the plant nutrition. Results showed a higher crop yield in HANP and ACPc treatments compared to the commercial fertilizer (monocalcium phosphate (MCP)), by 20 and 33%, respectively. The major difference was in resource use efficiency (RUE), a ratio of crop yield to P lost after irrigation, which was about six times higher in HANP than commercial MCP. These outcomes correlate well with dissolution characteristics that the leaching loss of dissolved P could be a major reason for the low yield and highly diminished RUE of ACPc and MCPs compared to those of HANPs. These outcomes provided multiple reasons for the need for the development of next-generation phosphorus fertilizers that are dually capable of enhanced nutrient as well as high resource use efficiency.</p></div>","PeriodicalId":653,"journal":{"name":"Journal of Nanoparticle Research","volume":"27 6","pages":""},"PeriodicalIF":2.1,"publicationDate":"2025-05-27","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://link.springer.com/content/pdf/10.1007/s11051-025-06338-7.pdf","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144140290","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"材料科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Copper-based agrochemicals, widely used to protect crops from diseases, pose risks to non-target microorganisms and groundwater due to their uncontrolled application. This study addresses these challenges by developing a controlled delivery system for Cu-based agrochemicals, enhancing their efficacy and minimizing environmental impact in agricultural applications. We investigated the synthesis of CuS nanoparticles (NPs), followed by surface modification and entrapment of hydrophobic CuS NPs in engineered lignin NPs. CuS NPs exhibited a size between 8.8±1.3 and 14.7±3.3 nm, depending on the duration of the reaction, 15 to 30 min, respectively. Surface modification of CuS NPs with 1-octadecanethiol (ODT), a thiol with 18 carbons (R-SH), resulted in hydrophobic CuS NPs. FTIR revealed a layered assembly due to arranged alkyl chains on the CuS surface. Separately, two types of lignin, alkali (ALN) and sodium ligninsulfonate (SLN), were grafted with poly(lactic-co-glycolic) acid (PLGA) at 1:1 and 2:1 w/w ratios to form amphiphilic polymers, which were assembled into delivery systems for the CuS NPs. Hydrophobic CuS were successfully entrapped into LN-PLGA delivery systems to control the release of CuS under aqueous solutions. SLN-PLGA NPs were generally smaller (122 to 130 nm) compared to ALN-PLGA NPs (132–162 nm). Release of Cu and S from the ALN-PLGA delivery systems exhibited a consistent release of S at 0.49 ppm (0.6%) for 7 days while a slow dissolution of Cu of 0.02 ppm (0.02%) was observed over the same time frame. In conclusion, CuS NPs were successfully synthesized and modified, allowing their entrapment into LNP delivery systems with different properties, and controlled release over time. The lignin-based delivery systems are proposed as feasible alternatives for the efficient delivery of CuS in nanoform, utilizing an abundant biodegradable resource for improving plant health.</p></div>","PeriodicalId":653,"journal":{"name":"Journal of Nanoparticle Research","volume":"27 6","pages":""},"PeriodicalIF":2.1,"publicationDate":"2025-05-24","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://link.springer.com/content/pdf/10.1007/s11051-025-06327-w.pdf","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144125762","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"材料科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

In this study, a unified cohesive energy-based theoretical model is developed to predict the size-dependent melting temperature and optical bandgap of cadmium selenide (CdSe) and zinc selenide (ZnSe) nanoparticles. The model is implemented through MATLAB® simulations, utilizing a geometric scaling approach based on the surface-to-volume atomic ratio. The results reveal that for CdSe, the optical bandgap increases from ~ 1.74 eV (bulk) to ~ 2.21 eV at 4 nm, while the melting temperature decreases from ~ 1510 to ~ 1316 K. Similarly, ZnSe nanoparticles show a bandgap increase from ~ 2.70 to ~ 3.39 eV and a melting temperature reduction from ~ 1795 to ~ 1568 K. These trends are attributed to the dominant role of under-coordinated surface atoms and the consequent reduction in cohesive energy. The model predictions demonstrate strong agreement with experimental measurements and theoretical frameworks, establishing a pronounced inverse correlation between thermal stability and optical bandgap energy.

NPs influence forest trees at molecular and physiological levels, with effects varying by type, size, concentration, and environmental context.
