The article examines how hybrid nanofluids can significantly improve the efficiency of PTC used in solar thermal energy applications. The aim is to evaluate recent advancements in hybrid nanofluids, focusing on their thermophysical properties and their impact on PTC efficiency. The objective is to provide a comprehensive analysis of thermal, optical, and rheological characteristics, identify research gaps, and propose future directions for optimizing PTC performance. By incorporating a mixture of different nanoparticles into a single base fluid, hybrid nanofluids achieve enhanced thermal properties and more efficient heat transfer than single-particle nanofluids, achieving thermal efficiency improvements of up to 2.8% in PTCs and 197% in solar collectors. Notably, Al₂O₃/water nanofluid at 3% concentration increased thermal efficiency by 28%, from 40.8% to 52.4%. The novelty lies in integrating nanoparticle functionalization, surfactant-assisted stabilization, and passive techniques like turbulators to enhance stability and exergy efficiency. Challenges such as long-term stability, viscosity-related pressure drops, and scalability are addressed, offering insights for sustainable solar energy harnessing and green hydrogen production.

Under microalgae-based biofuels, it provides an option for the replacement of conventional fuels with an alternative energy source, rapid algal growth with the possibility of high accumulation of lipids along with capturing carbon and remediating wastewater among others. In this regard, the study comparatively analyzed the biofuel production efficiencies of Spirulina platensis and Chlorella vulgaris in a rice water-based medium (wastewater), supplemented by True water, which is an artificial water. The preparation of growth medium for Spirulina involved modification of Zarrouk's using agricultural rice water. The culture of Chlorella powdered water (3g) and Spirulina culture (100 mL per liter in two separate beakers) was carried out under controlled light and aeration conditions. Lipids were extracted by methanol and chloroform, while transesterification was done by sodium hydroxide and methanol. However, the yield obtained was very low (<1 mL) at the end of the entire optimization of the cultivation, lipid extraction, and transesterification processes. It was found that Chlorella had better growth and lipid productivity than Spirulina in wastewater cultivation. Both gases were tested for their ability to sequester CO₂ by microalgae, plus their nutrient pollutant removal (nitrate and phosphate). Improvements in biomass concentration and optimizing solvent systems and harvesting techniques would contribute to improving biofuel yields in future studies. Recommended further tests for a more extensive characterization of biodiesel quality and energy content include lipids profile analysis (GC-MS) and calorific value testing of the extracted biofuel.

Seaweed, an abundant marine resource, has long been recognized for its nutritional, medicinal, and ecological significance. Seaweed has been used traditionally in feminine hygiene practices for its absorbent and soothing properties, particularly in coastal communities. Modern innovations now utilize seaweed-derived biopolymers like alginate and carrageenan in biodegradable sanitary products, offering antibacterial, anti-inflammatory, and eco-friendly alternatives to synthetic materials. Seaweed-based supplements also contribute to menstrual and reproductive health. Beyond hygiene, seaweed cultivation empowers women economically, especially in coastal regions. However, further research is needed to validate the clinical efficacy of these products and optimize their use in sustainable hygiene solutions.

The Nigerian electricity network, with an average generation capacity of 5500 MW, face significant challenges due to constrained power, leading to grid instability and inefficiencies. This research presents a comprehensive framework for harnessing excess power within the Nigerian grid, emphasizing its application in ancillary services and grid balancing. The proposed framework integrates energy storage systems, demand response programs, as well as renewable energy sources, offering a strategic approach to optimize grid performance and enhance reliability. Through simulation studies and optimization models, the research demonstrates the viability of this framework in addressing the challenges of the Nigerian power sector, contributing to the sustainability and modernization of the electricity grid.

Pantaprazole was estimated using a straightforward, sensitive, and selective UV approach that was devised and verified. The technique was developed using UV spectrometry; the optimal concentration was 10µg/ml, the absorbance was 0.449, and the λmax was reached at 292nm with solvent water: ethanol (8:2 V/V). The linearity range of the test technique was 0.5 µg/ml to 16 µg/ml, which had an R2 value of 0.999. It was discovered that the accuracy % assay 98.64-99.96%. The results indicated that the intraday precision and interday precision % RSD values were found in between 0.32 -0.52. The developed method's LOD and LOQ were 0.15µg/ml and 0.44 µg/ml respectively. The robustness results were found to be 99.72%-101.78% for wavelength variation and organic phase change.

At CDL we work with librarians and archivists from across the ten University of California campuses. More specifically, as the team that maintains and augments our digital preservation repository, Merritt, we assist a variety of depositors with their digital preservation initiatives. Though most depositors are extensively familiar with the file formats and metadata of their content when it is ingested, preserving collections will, in a chronological sense, stretch beyond any one group of individuals. Therefore, a key challenge we face over time is to provide the means for current and future staff to thoroughly analyze the contents of their collections, at scale. This presentation will discuss a solution the Merritt team at CDL created to address the need to analyze the metadata, digital object structure and file types in the numerous collections being preserved in the repository. The solution leverages Amazon OpenSearch and its data visualization tools. We've found that OpenSearch has allowed us to create a rich map of relationships across elements of object data, and in turn lend depositors the necessary knowledge to make informed preservation decisions related to the metadata and structure of the objects in their collections and regarding file format sustainability.
