Evaluation of the Influence of Salt Treatment on the Structure of Pyrolyzed Periwinkle Shell

Journal of Applied Sciences and Environmental Management, 2013
This paper investigates the effect of use zinc chloride in varying impregnation ratios ranging between 0.1 and 1.5 to chemically activate carbonized periwinkle shells. Studies to characterize the activated carbon were conducted at ambient conditions. The

REVIEW OF THE DEVELOPMENT OF PERIWINKLE/PALM KERNEL SHELL-REINFORCED EPOXY MATRIX HYBRID COMPOSITES FOR BRAKE PAD PRODUCTION [PDF]

European Journal of Materials Science and Engineering
Asbestos has traditionally been used in brake pad production due to its durability, but concerns over its health hazards, non-biodegradability, and high cost have prompted the search for safer alternatives.

Local Conditions and Environmental Gradients Shape the Abundance and Size Structure of a Non-Native Intertidal Species in Atlantic North America. [PDF]

Ecol Evol
We investigated how density and body size of the non‐native intertidal snail Littorina littorea vary along a 10° latitudinal gradient (> 1700 km) in North America. Our analyses show that local substrate complexity drives density patterns, whereas body size is shaped by climatic factors, with higher and more variable summer temperatures reducing ...

Trematode infection buffers heat stress in blue mussels Mytilus edulis: The role of heat shock proteins. [PDF]

J Anim Ecol
The study shows that parasite infection changes heat shock protein expression and can increase heat tolerance in blue mussels. By separating parasite and temperature effects, the results suggest that infection may improve survival during heat stress, highlighting important parasite–host interactions for climate change resilience. Abstract The influence

Performance evaluation of a domestic vapor compression refrigeration system using periwinkle-shell-derived CaO-rich nano-lubricant in mineral oil

Journal of Materials Science: Materials in Engineering
This study presents a novel approach to improving the performance of domestic vapor compression refrigeration systems (VCRS) through a bio-synthesized nano-lubricant derived from periwinkle shells, a biodegradable waste material. Periwinkle-shell-derived

Effect of adsorption variables on the removal of Cadmium ions from wastewater using activated periwinkle shell from Okada, Edo State

The Proceedings of the Nigerian Academy of Science, 2022
This paper details the effect of adsorption variables on the removal of cadmium ions from wastewater using activated periwinkle shell. The periwinkle shells were carbonized for 1.5h for 900oC, and activated using HNO3 and calcium chloride solution.
