In this regard, nanoparticles (NPs) possessing enormous potential properties can be obtained using various facile methods for several applications. Adopting NPs as primitive building blocks can initiate the formation of complex entities named supraparticle (SP) to create several advanced functional materials. Additionally, SPs enable entirely new material characteristics to the system, owing to their individual entities, intrinsic properties such as coupling, spatial arrangement, and co‐localization. Indeed, methods such as template‐induced evaporation‐based assembly of NPs direct the shape, size, and morphology of SPs from their respective colloidal dispersions on a solvent‐repellant solid surface. Therefore, it is important to comprehend the formation of SPs and their structure‐property relationship with respect to practical application. This review presents a brief overview of SPs assembly by outlining the templated‐assisted evaporation‐based methodologies for synthesizing SPs. Further, the effect of various factors on the interaction between colloidal entities, solvent, and substrate, leading to the genesis of SPs is elaborated. Conclusively, specific properties are described and applications of SPs for energy storage, generation, and environmental remediation are reported, which collectively brings many interdisciplinary research fields to the same podium.","PeriodicalId":19903,"journal":{"name":"Particle & Particle Systems Characterization","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2023-10-26","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"134908780","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}

Herein, a facile and efficient hydrothermal approach is reported for obtaining various complex Nb 2 O 5 nanostructures, including thin sheets, thick flakes, spiky and elongated spiky sea urchin morphologies using urotropin as a growth‐directing and hydrolyzing agent in various mixed and pure solvents. The detailed structural and chemical composition, surface morphology and crystallinity of as‐synthesized Nb 2 O 5 nanostructures are presented. The urotropin concentration, reaction time, and water‐ethanol solvent mixture play a critical role for obtaining the elongated spiky sea urchin morphologies. The spiky Nb 2 O 5 structures show a pseudohexagonal phase with less urotropin content, while thin sheets are obtained with a higher urotropin concentration and are primarily amorphous. These structures undergo transformation in their crystal phase and morphologies during calcination at higher temperatures revealing the active role of urotropin in stabilizing them. A composite of spiky sea urchin Nb 2 O 5 ‐carbon nanospheres (suNb 2 O 5 ‐CNS) is achieved by in‐situ growth of Nb 2 O 5 in the presence of CNS without compromising on morphology, phase, and crystallinity. suNb 2 O 5 ‐CNS composite is shown to possess higher charge storage capacity compared to its constituents for supercapacitor applications.","PeriodicalId":19903,"journal":{"name":"Particle & Particle Systems Characterization","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2023-10-25","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"135170425","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}

The prime purpose of this research study is to demonstrate a controlled release of Quercetin from formulation of quercetin (Qu)‐based layered nanocarriers (LNCs) with higher stability and anti‐diabetic activity. The QuLNCs are synthesized using the nanoprecipitation method and optimized by Box‐Behnken design of the Design of Experiment (DoE) method. The Quercetin Nanoparticles (QuNPs) are prepared using Polyvinyl alcohol (PVA) and Poly (D,L‐ lactic‐co‐glycolic acid) (PLGA) polymers where the two layers of Phenylboronic acid (PBA) are conjugated using 3‐amino propyl‐triethoxysilane (APTES) as a functionalizing agent followed by PEGylation of the entire system using PEG 2000 . The optimized QuLNCs are characterized by various parameters like Particle size (PS), Zeta potential (ZP), % Entrapment efficiency (%EE), Attenuated total reflectance‐ Fourier Transform Infrared Spectroscopy (ATR‐FTIR), Differential scanning Calorimetry (DSC), Transmission electron microscopy (TEM), in vitro as well as in vivo studies. The QuLNCs showed a % entrapment efficiency of 82.846 ± 0.957% and release of 85.04 ± 3.21% of Qu for 24 h from the layered nanocarriers. The in vivo studies of QuLNCs exhibited a significant controlled release of quercetin for modulating blood glucose levels. Hence, these results proved QuLNCs system acts as a favorable approach for the treatment of type 1 diabetes to offer a longer duration of action.","PeriodicalId":19903,"journal":{"name":"Particle & Particle Systems Characterization","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2023-10-23","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"135405145","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}

Furthermore, research results indicated that the RACN showed superior broad‐spectrum catalytic performance for the reduction of aromatic nitro compounds, and the catalytic efficiency of the RACN is enhanced dozens of times by the treatment.
