As a result, new and improvedantibacterial drugs are urgently needed. Similarly, when some unwanted foreign pathogensenter the cellular premises to disturb its homeostasis, inflammation develops as an immune reaction. However, these immune responses also become a double-edged sword when the inflammatory reaction lasts for a long time, and pain is also linked to inflammatory responses. Inflammation and pain are both signs of tissue injury. Pain is,by definition, an unpleasant experience that ultimately interferes with their normalwell-being. Hence, bacterial infection, inflammation, and pain need medical assistance to maintain homeostasis. Conventional medicines possess so many repercussive effects, which then demand a replacement with a less toxic and more efficient modern drug. In their review article, for the first time, they present recent advancements in biomedical applications such as the antimicrobial, anti-inflammatory, and analgesic properties of noble metal nanoparticles. Noble metals have limited availability in the earth's crust. Hence, their physicochemical characterizations and applications are greatly limited. Still, there are some interesting research findings that offer a significant ray of hope for the health sector all over the world.","PeriodicalId":19903,"journal":{"name":"Particle & Particle Systems Characterization","volume":null,"pages":null},"PeriodicalIF":2.7,"publicationDate":"2023-12-28","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"139053874","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}

However, challenges such as particle aggregation and rapid copper oxidation affect nanoscale production. This study systematically investigates the synthesis of colloidal Cu-NPs using chitosan (Cts) as a stabilizer and reducing agent in the arc discharge system, comparing it to distilled water as a medium. Confirmation of the purity, size, and morphology of the Cu-NPs is achieved through various physicochemical characterization methods. X-ray diffraction patterns confirm the synthesis of highly pure face-centered cubic (fcc) crystal Cu-NPs. UV–vis analysis reveals absorption peaks at 572–585 nm, indicating pure copper. Fourier-transform infrared spectroscopy shows peaks at 638 and 597 cm−1, corresponding to Cu─Cts bonds. Transmission electron microscopy images depict spherical nanoparticles ranging from 15 to 45 nm, with smaller sizes at higher Cts concentrations. The catalytic activity of Cu-NPs in the degradation of 4-nitrophenol to 4-aminophenol is assessed, with Cu-NPs synthesized in distilled water demonstrating superior catalytic properties compared to 0.10 wt.% Cts. This study highlights the efficacy of the arc discharge method in producing pure, uniformly sized Cu-NPs with potential applications in catalysis.","PeriodicalId":19903,"journal":{"name":"Particle & Particle Systems Characterization","volume":null,"pages":null},"PeriodicalIF":2.7,"publicationDate":"2023-12-25","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"139035820","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}

These particles are synthesized and enlarged using an improved hydrolysis method, resulting in highly crystalline (96.5%), low polydispersity (15.1%), and readily dispersible colloids in water. The aqueous mesomorphic system is characterized for the isotropic-to-nematic phase transition by analyzing number density and shear viscosity. Thermal stability is assessed through thermogravimetric analysis. Additionally, kinetic and thermodynamic parameters for 2D gibbsite nanoparticles are determined for the first time using three models (Coats-Redfern, Friedman, and Kissinger). In particular, the activation and Gibbs free energies for the first dehydration stage of gibbsite yield ranges of 98‒128 kJ mol−1 and 135‒161 kJ mol−1, respectively. To investigate the confinement effect of colloidal gibbsite-LCs, an isotropic gibbsite dispersion is introduced into a tube, leading to the uniform formation of gibbsite-LC layers along two distinct pathways: tangential to the liquid-air interface and as concentric circles along the tube walls. These findings offer valuable insights into potential applications, particularly in the domain of gas barrier inorganic films across various specialized fields.","PeriodicalId":19903,"journal":{"name":"Particle & Particle Systems Characterization","volume":null,"pages":null},"PeriodicalIF":2.7,"publicationDate":"2023-12-19","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"138826401","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}

However, current research predominantly examines isolated cavitation bubbles, overlooking real-world LAL scenarios where numerous bubbles interact simultaneously. This study addresses this gap by investigating the effects of short-range micrometric spatially controlled double-pulse laser ablation in liquids on nanoparticle size distribution. Gold and YAG are used as model materials, and a dimensionless parameter, H*, is introduced to quantify the ratio between double bubble spatial separation and their maximum height. This parameter correlates with cavitation bubble merging time, bubble volume change rate, and subsequent nanoparticle size increase. Shadowgraphs provide valuable insights into bubble contact and fusion dynamics, showcasing phase separation by a thin water film and subsequent merging into a single bubble. Notably, a twofold increase in nanoparticle size is observed for both Au and YAG at H* = 0.25. The research indicates a strong association between nanoparticle size trends and cavitation bubble volume rate change, particularly emphasized at H* = 0.25. Understanding the dynamics of neighboring bubbles during LAL emphasizes the relevance of lateral pulse distances in dual-beam LAL, impacting particle size distribution in a distance-dependent manner.","PeriodicalId":19903,"journal":{"name":"Particle & Particle Systems Characterization","volume":null,"pages":null},"PeriodicalIF":2.7,"publicationDate":"2023-12-19","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"138826496","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}

Despite these concerns, there is currently limited understanding of the potential adverse effects of engineered nanomaterials on fibrin clot formation. This is surprising, given that fibrinogen is highly concentrated in plasma and has a large surface area, making it prone to unintended interactions with nanomaterials. In this study, the impact of ultrasmall gold nanoparticles (usGNPs) on fibrin clot formation is investigated. UsGNPs have gained significant interest in biomedical applications due to their unique physicochemical properties and favorable behavior in complex biofluids. It is found that the usGNPs interacted with fibrinogen, delayed the onset of clot formation, and became physically trapped within the forming fibrin matrix. Confocal microscopy showed that the usGNPs disrupted the normal architecture of the fibrin clot, resulting in a less dense network structure. This disruption led to larger clot pore sizes and increased clot permeability to liquid. Considering the potential health risks associated with abnormal clot formation, a detailed examination of the clot formation process should be included in the standard safety assessment of usGNPs and other nanomedicines.","PeriodicalId":19903,"journal":{"name":"Particle & Particle Systems Characterization","volume":null,"pages":null},"PeriodicalIF":2.7,"publicationDate":"2023-12-06","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"138556963","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}

However, the reported CDs derived from coal pitch are mainly limited blue emission. Here, a new route to synthesize yellow-emissive CDs from coal pitch is developed by extracting the lightweight aromatic compounds from coal pitch and solvothermally treating the extracts in dichloromethane in the presence of a small amount of nitric acid and sulfuric acid. Notably, the obtained CDs exhibit excitation independent yellow emission, large Stokes shift and good photostability. The application of the CDs for luminescent solar concentrators (LSCs) is evaluated. It is found that the CDs can be well dispersed in polymethyl methacrylate (PMMA) matrix and fabricated transparent LSCs. The synthesized LSC (4 × 4 × 0.2 cm3) with the optimal CDs concentration exhibits an optical conversion efficiency (ηopt) of 3.31% and power conversion efficiency (ηPCE) of 1.95% under simulated sun light illumination (100 mW cm−2).
