Antibacterial characteristics of heated scallop-shell nano-particles.
Heated scallop-shell (HSS) nano-particles, prepared using a wet grinding mill, and microparticles were examined for their antibacterial activity against vegetative bacterial cells and spores. The median diameters of the nano-particles and micro-particles were approximately 20 nm and 30 µm, respectively. The antibacterial activity of HSS against Escherichia coli increased with an increase in con...
متن کاملInspired by Abalone Shell: Strengthening of Porous Ceramics with Polymers
INTRODUCTION Alumina ceramics have long been of technological importance. However, their brittleness limits their potential for use in structural applications. Traditional approaches proposed to improve the strength and reliability of ceramics include: decrease flaw size, improve fracture toughness and flaw insensitivity, and decrease applied stresses. Polymers on the other hand, although weak,...
متن کاملThe Effect of Zinc Oxide Scallop-Shell Powder and Complications After Coronary Angiography
Introduction: Coronary angiography is often associated with complications such as hemorrhage and hematoma that should be considered and be minimized. Objective: This study aimed to determine the effect of Zinc oxide scallop-shell powder as a topical hemostatic agent (composed mainly of calcium) on complications after coronary angiography. These complications include hemostasis time, low back p...
متن کاملShell Growth in the Scallop Argopecten Irradians. I. Isotope Incorporation with Reference to Diurnal Growth.
1. Incorporation of calcium and carbonate into shell has been studied in the scallop Argopecten irradians using 45Ca and 14C-bicarbonate. 2. The incorporation of 45Ca and 14C-carbonate into shell was linear with time after a lag period of 1 to 2 hours. The shell-forming mantle tissue attained a steady state with respect to 45Ca in the sea water medium within 2 hours. 3. The molar ratio of 45Ca ...
متن کاملMorphological convergence of shell shape in distantly related scallop species (Mollusca: Pectinidae)
Morphological convergence is a central concept in evolutionary biology, but convergent patterns remain understudied in nonvertebrate organisms. Some scallop species exhibit long-distance swimming, a behaviour whose biomechanical requirements probably generate similar selective regimes. We tested the hypothesis that shell shape similarity in long-distance swimming species is a result of converge...
