Journal of Applied Polymer Science, EarlyView.This study explores the mechanical properties of HDPE‐based composites reinforced with walnut shell (WS) and Nano‐CaCO3. The addition of Nano‐CaCO3 enhanced tensile and flexural strength, demonstrating its reinforcing effect. These findings highlight the potential of HDPE/WS/Nano‐CaCO3 composites for structural applications, offering insights into ...

Thermal‐Infrared Measurements of the North‐East Tower at Ardrossan Castle
Archaeological Prospection, EarlyView.ABSTRACT Thermal‐infrared imaging of buildings is used to investigate a range of phenomena including the accumulation of moisture. In general, the presence of moisture poses a direct danger to historic structures and must be characterized prior to any intervention.

Synthesis of a spinifex‐textured basalt as an analog to Gusev crater basalts, Mars [PDF]
Meteoritics & Planetary Science, 2012 Abstract– Analyses by the Mars Exploration Rover (MER), Spirit, of Martian basalts from Gusev crater show that they are chemically very different from terrestrial basalts, being characterized in particular by high Mg‐ and Fe‐contents. To provide suitable analog basalts for the International Space Analogue Rockstore (ISAR), a collection of analog rocks ...

Archaeometric Analyses of Medieval Pottery from the Lower Danube Region, Romania
ChemPlusChem, EarlyView.This study is about the pottery manufacturing in the Lower Danube region during the Early Medieval period (8th–10th c. AD). Optical microscopy, Particle induced X‐ray emission, and X‐ray diffraction analyses performed on 32 representative ceramic shards excavated at Pantelimonu de Sus, Constanţa County, Romania, provide clues on the raw materials and ...

Clinopyroxene Dissolution Records Rapid Magma Ascent
Frontiers in Earth Science, 2020 Magma ascent rates control volcanic eruption styles. However, the rates at which basaltic magmas ascend through the crust remain highly uncertain. Although recent studies have successfully exploited records of decompression driven degassing to estimate ...

The Depositional Record, EarlyView.Halite thickness in Mbr 2 of the Kumugeliemu can reach 1000 m. The thick halite is associated with sedimentary rock with shallow water fabrics. The thick halite was formed in a shallow‐sea water environment. The ‘Multiple transgression‐salt‐forming’ model was established.

How Much Water in Basaltic Melts Parental to Porphyry Copper Deposits?
Frontiers in Earth Science, 2020 Porphyry copper deposits are formed by aqueous fluids exsolved by differentiated, mantle-derived magmas variably mixed with crustal melts. Water is essential to form porphyry Cu mineralization, and this explains why these deposits are found only at ...
