Titanium Suboxides Responsible for Electronic Anomaly Near Room Temperature in the Ti3C2Tx MXene

Advanced Functional Materials, EarlyView.
Our multi‐technique study reveals that the near‐room‐temperature anomaly in Ti3C2Tx MXene is linked to titanium suboxide nanodomains, including Ti3O5, embedded within the MXene host. Their temperature‐driven transformation provides an alternative explanation to solvent‐ and swelling‐based models and offers new insight into the thermally activated ...

Synergizing remote sensing, support vector machine, and aeromagnetic data for precise lithological and mineral potential mapping: a case study from Egypt

Geo-spatial Information Science
Precise lithological mapping is not only a strong key for exploring new mineralized areas but also could help in achieving the optimal exploitation of mineralized regions. In the present case, cause lithological mapping may provide advice not only to the

Near‐Infrared Light‐Driven Zn/Au Janus Micromotors for Multiplex SERS Detection of Anticancer Drugs

Advanced Functional Materials, EarlyView.
Zn/Au Janus micromotors, propelled by thermophoretic effects under NIR light, function as active SERS platforms for single and multiplex detection of anticancer drugs. Their dynamic motion enhances analyte exchange at the Au interface, reducing saturation and competitive adsorption, thereby improving sensitivity and extending the linear detection range.

Experimental research on the formation of mineral-rich areas in residue gold placer deposits

E3S Web of Conferences, 2018
Underestimation of the reserves of raw material base of gold mining (namely residue dump complexes) leads to negative social and economic consequences in the regions engaged in placer gold mining. Nonetheless, their efficient development is possible only

Morphological and Minor Element Fingerprinting for Source Identification of Placer Gold from the Vulture Mine Area

, 2014
The Vulture Mine, with over 340,000 ounces of reported gold production, is a historically important mine in Arizona. Four samples of placer gold from the area around the mine were examined in regards to geochemistry and morphology.
