Mechanisms of near‐normal sea water dolomitisation: Mesohaline‐reflux or syn‐depositional?
This study investigates the dolomitisation of the Eocene Dammam Formation on the Arabian Plate using petrographic, mineralogical, geochemical and isotopic analyses. The findings reveal two distinct dolomite types, formed primarily through normal‐to‐mesohaline sea water dolomitisation, challenging previous models such as sabkha‐meteoric mixing.

Domed‐rim microbial polygons and their preservation potential
Microbially induced sedimentary structures (MISS) derive through interactions between minerals and microorganisms. We define a domed‐rim MISS, morphologically distinct from abiotic mud cracks and demonstrate its potential for long‐term preservation. These structures represent promising biosignatures in ancient environments on Earth and potentially Mars.

Eu2O3-functionalized ZnO/palygorskite
Eu2O3-functionalized ZnO/palygorskite was synthesized in a two-step method, and was thoroughly characterized. Energy was transferred from Eu2O3 to ZnO, but not from ZnO to Eu2O3, in contrast to literature reports. The interaction between Eu2O3 and ZnO directly influenced the energy transfer process.

Determination of Total Acid in Palygorskite Chemically Modified by N-Butylamine Thermodesorption
The acid properties of palygorskite clay (R1) were studied using n-butylamine as probe molecule. A comparison was made of these properties in palygorskite clay (R1), in an acidified palygorskite (R2) and in acid palygorskite loaded with 2% of lanthanum ...

Engineering Crystalline Structure of In2O3 for Enhanced Electroreduction of CO2 to Formate
A series of In2O3 catalysts with unique crystallographic structures (h‐In2O3, c‐In2O3, and h/c‐In2O3) is methodically obtained for electroreduction of CO2 to formate. The h‐In2O3 catalyst demonstrates a higher Faradaic efficiency of formate and current density than c‐In2O3 and h/c‐In2O3.

Adsorption of terpenes compounds onto palygorskite
The present work aimed to study the processes of the synthesis insecticidal formulation. The active compounds of essential oil of eucalyptus globulus were fixed in the palygorskite by adsorption process. Two samples types of palygorskites were used; raw
