Iron Salts, but Not Iron Oxide Nanoparticles, Drive High‐Yield Production of Iron‐Engineered Extracellular Vesicles

Journal of Extracellular Vesicles, Volume 15, Issue 8, August 2026.
Soluble iron, but not iron oxide nanoparticles, is efficiently routed into extracellular vesicles (EVs) through physiological cargo‐sorting pathways. Prolonged ferric salt incubation combined with turbulence‐based hydrodynamic stimulation drives massive EV secretion and near‐complete intracellular iron transfer via ferritin.

Mineralogie descriptiva

, 2005
In the book we have selected and described the most important minerals from the point of view of spreading and participation in the composition of the terrestrial crust and in terms of economic and scientific significance. The book was adopted the latest concepts on mineral systematic model proposed by IMA (International Mineralogical Association). The

Carbonate‐Associated Sulfate Does Not Record Superheavy δ34S in Deep Scandinavian Bedrock Fractures: Implications for Pyrite Formation in the Deep Biosphere

Geochemistry, Geophysics, Geosystems, Volume 27, Issue 8, August 2026.
Abstract In deep bedrock fractures of the Fennoscandian shield, pyrite with “superheavy” δ34S values of up to 147‰ exists together with calcite. The extreme variability and 34S‐enrichment in pyrite indicate that microbial sulfate reduction (MSR) evolved to almost complete sulfate exhaustion in closed‐system microenvironments.

Synthesis of novel derivatives of 5-hydroxymethylcytosine and 5-formylcytosine as tools for epigenetics

Beilstein Journal of Organic Chemistry, 2014
In this work we present for the first time the synthesis of novel 5-hydroxymethylcytosine (5hmC) and 5-formylcytosine (5fC) derivatives that can be used as tools in the emerging field of epigenetics for deciphering chemical biology of TET-mediated ...

Aluminum Phyllosilicate and Jarosite Formation Through Alteration of Reworked Al/Si‐Rich Volcaniclastic Sediments in Nili Fossae, Mars

Journal of Geophysical Research: Planets, Volume 131, Issue 8, August 2026.
Abstract Aluminum phyllosilicates occur in 1–10s of km2 exposures of Noachian (∼3.7 Ga) rock across Mars and typically appear stratigraphically above Fe/Mg‐phyllosilicates. These units have been proposed to represent pedogenic basalt weathering sequences.

Thermal histories of El Médano 300 (EM 300) and Northwest Africa 8155 (NWA 8155): Implications for the diversity of IAB‐ungrouped iron meteorites and their parent bodies

Meteoritics &Planetary Science, Volume 61, Issue 8, Page 1763-1787, August 2026.
Abstract This study provides the first petrographic, crystallographic, and chemical comparison between El Médano 300 (EM 300) and Northwest Africa 8155 (NWA 8155), two particular IAB‐ungrouped iron meteorites. Both contain exceptionally large graphite nodules and “flowers”, providing unique insights into carbon behavior in metallic melts and cooling ...

Transport of heavy minerals and heavy anthropogenic particles in the Rio Sella catchment and along the adjacent coast, northern Spain [PDF]

Eiszeitalter und Gegenwart
The Rio Sella in northern Spain drains a catchment area of around 1200 km2. It originates in the Picos de Europa and erodes a variety of outcropping lithologies, mainly of Palaeozoic and minor Mesozoic to Cenozoic age. These rocks include siliciclastics,

Origin and formation of a chondritic xenolith in Krymka (LL3.2, breccia): Indications for a late formation of the accretionary breccia

Meteoritics &Planetary Science, Volume 61, Issue 8, Page 2016-2047, August 2026.
Abstract An unusual chondritic xenolith was found in two sequentially prepared thin sections of a sample from the Krymka (LL3.2) chondrite. The xenolith has a rounded, slightly deformed shape of about 5 mm in apparent diameter and is partially surrounded by a double rim made of an inner fine‐grained silicate‐rich rim and an outer sulfide‐rich rim.
