The objective of this paper is to describe the new serpentine group mineral, guidottiite, which is analogous to cronstedtite. Guidottiite has an ideal chemical composition of (MnFe)(SiFe)O(OH)4. The sample is from the N'chwaning 2 mine, Kalahari manganese field, Republic of South Africa, and apparently forms from hydrothermal solutions. [...]

10 p, 1.1 MB Role of chitin in montmorillonite fabric : Transmission electron microscope observations / Kim, Jinwook (Yonsei University. Department of Earth System Sciences) ; Furukawa, Yoko (Stennis Space Center. Naval Research Laboratory, Seafloor Sciences Branch) ; Curry, Kenneth J. (University of Southern Mississippi. Department of Biological Sciences) ; Bennett, Richard H. (SEAPROBE, Inc.)
Particle concentration, charge, solution chemistry (i. e. ionic strength), and the nature of organic matter (OM) are the major factors controlling particle flocculation in aqueous environments. In the present study, the nature of clay fabric associated with clay-OM interaction at a range of ionic strengths was the focus. [...]

17 p, 2.6 MB Low-temperature hydrothermal alteration of trachybasalt at Conical Seamount, Papua New Guinea : Formation of smectite and metastable precursor phases / Giorgetti, Giovanna (Università di Siena. Dipartimento di Scienze della Terra) ; Monecke, Thomas (Department of Geology and Geological Engineering. Colorado School of Mines) ; Kleeberg, Reinhard (Institut für Mineralogie. TU Bergakademie Freiberg) ; Hannington, Mark D. (Department of Earth Sciences. University of Ottawa)
The conversion of volcanic glass to secondary alteration products is one of the most common mineralogical transformations during low-temperature hydrothermal alteration of submarine basalts. To better understand the mechanism and kinetics of this transformation, porphyritic and formerly glassy trachybasalt, recovered from Conical Seamount, Papua New Guinea, was studied in detail. [...]

Department of Microbiology)
Mineralization of microbial biomass is a common phenomenon in geothermal habitats, but knowledge of the structure of the minerals formed in these environments is limited. A combination of spectroscopic, microscopic, and stable isotopic methods, as well as the chemical analysis of spring water, were employed in the present study to characterize calcium carbonate minerals deposited in filamentous cyanobacterial mats in different locations of La Duke hot spring, a circumneutral thermal feature near the north entrance of Yellowstone National Park, Montana, USA.

Department of Earth System Sciences) ; Dong, Hailiang (Miami University. Department of Geology)
Electron energy-loss spectroscopy (EELS), energy-filtered transmission electron microscopy (EFTEM), and high-resolution transmission electron microscopy (HRTEM) have been applied in mineralogy and materials research to determine the oxidation states of various metals at high spatial resolution.

We investigated pseudo-cubic CuTe nanosheets using electron diffraction tomography and high-resolution HAADF-STEM imaging. The structure of this metastable nanomaterial, which has a strong localized surface plasmon resonance in the near-infrared region, was determined ab initio by 3D electron diffraction data recorded in low-dose nanobeam precession mode, using a new generation background-free single-electron detector.

Therapeutic drug carriers can drive their cargo to their target cells. However, an obstacle is usually the entrapment of the drug inside the endolysosomal compartment, which physically impedes its actuation by the impossibility of reaching its molecular site of action. [...]
