Abstract Rock fragments of the Cb-type asteroid Ryugu returned to Earth by JAXA Hayabusa2 mission share mineralogical, chemical, and isotopic properties with Ivuna-type (CI) carbonaceous chondrites. Similar CI chondrites, these underwent extensive aqueous alteration consist predominantly hydrous minerals likely formed in presence liquid water on parent asteroid. Here we present an situ analytic...

Nanomineralogy is the study of Earth and planetary materials at nano-scales, focused on characterizing nanofeatures (like inclusions, exsolution, zonation, coatings, pores) in minerals and revealing nanominerals and nanoparticles [1,2]. With advanced high-resolution analytical scanning electron microscopy, we are now capable to characterize solid materials in situ easier and faster down to nano...

The lunar rocks described in the next chapter are unique to the Moon. Their special characteristics— especially the complete lack of water, the common presence of metallic iron, and the ratios of certain trace chemical elements—make it easy to distinguish them from terrestrial rocks. However, the minerals that make up lunar rocks are (with a few notable exceptions) minerals that are also found ...

The objective of this study was to compare the use of thermal combustion (CNS) and inductively coupled plasma (ICP) to measure the total S content in plant-, animal-, and mineral-based feedstuffs, and to provide concentrations of other macro- and micro-minerals contained in these feedstuffs. Forty-five feedstuffs (464 total samples) were obtained from suppliers as well as swine feed and pet foo...

Radhuni (Carum roxburghianum Benth.) seeds of three indigenous cultivars grown in Bangladesh have been studied for minerals and various compositional properties as well as assess their role in human nutrition. Variability was observed among investigated cultivars in terms of physical characteristics (e.g. seed volume, seed density, hydration capacity, hydration index, swelling capacity and swel...

Magnetotactic bacteria (MTB) biomineralize magnetosomes, nano-scale crystals of magnetite or greigite in membrane enclosures that comprise a permanent magnetic dipole in each cell. MTB control the mineral composition, habit, size, and crystallographic orientation of the magnetosomes, as well as their arrangement within the cell. Studies involving magnetosomes that contain mineral and biological...
