These fluids not only act as a primary barrier but are also responsible for maintaining hole integrity, carrying and lifting the drilled cutting and preventing the fluid loss. All these characteristics can be achieved by the help of desired rheological properties. Silica-coated iron oxide nanoparticles (0.25 and 0.5 wt. %) and activated carbon (0.25 and 0.5 wt. %) are being utilised in this study to formulate stable and high-performance water-base drilling fluids. The rheological characteristics of the mud system were investigated using different rheological parameters that consist of plastic viscosity, yield point, apparent viscosity and gel strength. On the other hand, the stability of the mud systems was observed with the help of intensity profile plots and interactive 3D surface plots using image processing technique. It is a novel method of spotting the changes in mud stability under no circulation condition. The results of the study reveal that all the muds showed pseudo-plastic shear thinning behaviour with flow index &lt; 1. No substantial changes in mud density were recorded after the addition of these particles. The maximum mud weight of 8.8 ppg was recorded in activated carbon samples. All the rheological properties were obtained at ambient conditions of 27 °C. It was observed that samples 1 and 4 demonstrate rheological characteristics in the desired operating range with optimum yield point-to-plastic viscosity ratio in range of 0.75–1 <span>(frac{{{raise0.7exhbox{${lb}$} !mathord{left/ {vphantom {{lb} {100ft^{2} }}}right.kern-0pt} !lower0.7exhbox{${100ft^{2} }$}}}}{cP})</span>. This ratio indicates that the concentration of both the particles is the key factor in achieving desire cutting carrying capacity. Moreover, according to intensity profile plots for the determination of mud stability, the sample with least concentration of activated carbon was the most stable sample. No substantial change in stability was recorded in that sample after two days of experimentation. On the contrary, silica-coated iron oxide nanoparticles start to de-phase on Day 1, and separation was quite visible on Day 2. On Day 5 of the stability test, it was perceived with the help of 3D surface plots that each sample was undergoing either solid settling phenomenon or dephasing. Based on the findings of the study, it can be concluded that activated carbon because of its high surface area and nontoxic behaviour can act as an efficient additive in terms of maintaining the rheological properties and stability of water-based mud system.</p></div>","PeriodicalId":471,"journal":{"name":"Applied Nanoscience","volume":"13 9","pages":"6405 - 6420"},"PeriodicalIF":3.674,"publicationDate":"2023-07-21","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"41229030","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"工程技术","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

However, administering minoxidil through remote drug loading and controlled release using lipid vesicles can be challenging, particularly for scalp applications in conditions like alopecia. Controlled release nano-medicine (CRNM) that delivers the minoxidil, using engineered nanoparticles, locally at a predetermined rate can overcome these side effects. For that, a novel minoxidil-loaded “shape anisotropic lipid nanoparticle” (SALN) is developed with a given composition and optimized for ultrasound processing conditions. That renders SALN with properties like multi-chambered bulk architecture with nano-reservoirs and shape anisotropy, with ultrasound activation, remote-loading, and controlled-release properties. The nanoparticles exhibited entrapment efficiency (32.2%) and drug release (99.01%) over 48 h and showed zero-order release kinetics. The nanoparticles are anisotropic as per HR-TEM. The HR-TEM studies showed that the SALN has a honeycomb-like bulk architecture with interconnected drug-loaded nano-reservoirs. It also revealed that the drug remains in different polymorphs at nanoscale inside the multi-chambered nano-reservoirs by DSC, TGA, and XRD. Drug release is significantly enhanced due to this nanoscale effect. The results of the design of experiments (DOE) to experimentally validated results are within 10% deviation. Moreover, the proposed controlled release system (SALN) for alopecia could improve local delivery to the hair follicle and is subjected to further studies. Subsequent research and development in this field can potentially revolutionize the management of alopecia and offer more effective and well-tolerated treatment options for patients.</p></div>","PeriodicalId":471,"journal":{"name":"Applied Nanoscience","volume":"13 9","pages":"6373 - 6391"},"PeriodicalIF":3.674,"publicationDate":"2023-07-17","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"41229428","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"工程技术","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
