Significance In solar-terrestrial systems, solar energy input has long been recognized to have a profound impact on Earth. The well-known photosynthetic systems enable sustainable solar-to-chemical conversion. However, no evidence yet emerged for the existence of widespread geological light-harvesting system. This study reveals such “photoelectric device,” where semiconducting Fe- and Mn (oxyhydr)oxide-mineral coatings are found overlay vast expanses natural rock/soil surfaces exhibit highly...
Background: The long-term chondroprotective effect of meniscal allograft transplant (MAT) and its superiority over meniscectomy have rarely been reported. Hypothesis: MAT would reduce osteoarthritis (OA) progression when compared with the meniscus-deficient knee. Graft extrusion distance strongly affect MAT. Study Design: Cohort study; Level evidence, 3. Methods: A total 17 knees receiving were followed up as group. group was further divided into nonextrusion subgroup (n = 9) 8) according to...
Abstract Electron transfer is the most elementary process in nature, but existing electron rules are seldom applied to high-pressure situations, such as deep Earth. Here we show a learning model obtain electronegativity of 96 elements under arbitrary pressure, and regressed unified formula quantify its relationship with pressure electronic configuration. The relative work function minerals further predicted by electronegativity, presenting decreasing trend because pressure-induced...
Re-oxidation of Cr(III) in treated Cr-contaminated sites poses a considerable source Cr(VI) pollution, necessitating stable treatment solutions for long-term control. This study explores the immobilization into chromite, most and weathering-resistant Cr-bearing mineral, under ambient conditions. Batch experiments demonstrate chromite formation at pH above 7 Fe(III)/Cr(III) ratios exceeding 1, with Fe(III) occupying all tetrahedral sites, essential stability. A theoretical model is developed...
Abstract Manganese (Mn) oxides have been prevalent on Earth since before the Great Oxidation Event and Mn cycle is one of most important biogeochemical processes Earth's surface. In sunlit natural environments, photochemistry has discovered to enable solar energy harvesting conversion in both geological biological systems. One widespread birnessite, which a semiconducting layered mineral that actively drives photochemical cycling Nature. The oxygen-evolving centre photosystem II (PSII) also...
Terrestrial hydrothermal systems have been proposed as alternative birthplaces for early life but lacked reasonable scenarios the supply of biomolecules. Here, we show that elemental sulfur (S0), dominant mineral in terrestrial hot springs, can reduce carbon dioxide (CO2) into formic acid (HCOOH) under ultraviolet (UV) light below 280 nm. The semiconducting S0 is indicated to a direct bandgap 4.4 eV. UV-excited produces photoelectrons with highly negative potential -2.34 V (versus NHE, pH...
Reductive immobilization has been a commonly used technique to detoxify Cr(VI) from soil; however, it's challenging remove the reduced Cr soil prevent its re-oxidation. This work explored natural magnetic composite for remediation, mineralization, and removal of soil. It consists 77% magnetite 23% pyrrhotite with strong properties. A series characterization tests show that composites are interlaced closely bonded, contain no other heavy metals. The rate increases decrease in particle size....
Abstract Calcification within breast cancer is a diagnostically significant radiological feature that generally consists of hydroxylapatite. Samples from 30 cases carcinoma with calcification were investigated using optical microscopy, energy-dispersive X-ray analysis, transmission-electron Fourier-transform infrared spectroscopy, Raman synchrotron radiation diffraction and fluorescence. Under the calcifications found to consist either irregular aggregates widths > 200 μm or spherical...
Based on the most active hydrosphere earth, interplay between adjacent semiconducting minerals and electrochemically microorganisms was scientifically researched in marine euphotic zone of Yellow Sea, China. Fe Ti were found suspended by ICP-MS EDS, probing element composition from macro to micro. Moreover, SR-XRD Raman indicated that iron titanium metal oxide situ such as anatase, rutile, brookite, goethite consisted minerals, notably, which retained prominent photo-response property...
The Danxia landform is representative of the Cretaceous continental red sediment. careful identification and potential environmental effects minerals in beds have yet to be clearly reported. In this work, reddish sandstone samples were collected from Lang Mountain Xinning, Hunan province, China, their mineral phases, element distribution, microstructure, spatial relationship different investigated using polarizing optical microscope, scanning electron microscopy, energy-dispersive X-ray...
