Evaluation of rheological and fluid loss properties of Nigerian bentonite using periwinkle and mucuna solannie

Cogent Engineering, 2021
Nigerian bentonite has low fluid loss control and poor rheological properties which are key API specifications. Foreign and imported bentonites are sodium-based, while local bentonites are calcium-based, and there is a need for beneficiation.

Trait compensation in marine gastropods: shell shape, avoidance behavior, and susceptibility to predation [PDF]

, 2004
Many organisms have evolved morphological and behavioral traits that reduce their susceptibility to predation. However, few studies have explicitly investigated the relationships between defensive traits and susceptibility. Here we demonstrate a negative

Poisson distribution:How tensile properties of particulate polymer composites are enhanced in a Poisson-motivated Taguchi method

Engineering and Applied Science Research, 2019
This paper examines how the Poisson distribution is being used to model thetensile properties of selected particulate reinforced polymer composites. While past studies have shown that the Taguchi method provides robust optimized composites forcost and ...

Iceberg Scour and Shell Damage in the Antarctic Bivalve Laternula elliptica [PDF]

, 2012
We document differences in shell damage and shell thickness in a bivalve mollusc (Laternula elliptica) from seven sites around Antarctica with differing exposures to ice movement. These range from 60% of the sea bed impacted by ice per year (Hangar Cove,

Investigating the performance of periwinkle shell tympanotonos fuscatus as energy storage material i

Journal of Thermal Engineering
Solar desalination remains a viable technique for addressing the lack of clean water in off-grid and arid locations. Low productivity and over-dependence on the available solar radiation are the main drawbacks of the technology.

PREPARATION AND INVESTIGATION OF THE PHOTOCATALYTIC PROPERTIES OF PERIWINKLE SHELL ASH FOR TARTRAZINE DECOLOURISATION [PDF]

Journal of Mechanical Engineering and Sciences, 2014
The discharge of dye-containing effluents into the aquatic environment represents a source of aesthetic pollution with associated negative effects. Photocatalytic degradation has been identified as a suitable means of treating these effluents.

Microemulsion‐Based Drilling Fluids Incorporating Seashell Residue Powder: A Sustainable Approach to Fluid Loss Control

Journal of Surfactants and Detergents, Volume 29, Issue 4, Page 537-547, July 2026.
Two microemulsion‐based drilling fluids incorporating SSRP were formulated using pine oil, the nonionic surfactant Alkonat L100W, and a glycerol/water solution. The results provide valuable insights into how surfactant‐assisted microemulsion systems can be engineered to enhance the performance and eco‐efficiency of drilling fluids.
