Geometallurgy of the Pebble porphyry copper-gold-molybdenum deposit, Alaska: Implications for gold distribution and paragenesis

, 2013
The Pebble Cu-Au-Mo deposit in southwest Alaska is one of the world's largest porphyry deposits. The deposit contains over 80 billion pounds (Blbs) Cu, 107 million ounces (Moz) Au, and 5.6 Blbs Mo in all resource categories.

All‐in‐One Analog AI Hardware: On‐Chip Training and Inference with Conductive‐Metal‐Oxide/HfOx ReRAM Devices

Advanced Functional Materials, EarlyView.
An all‐in‐one analog AI accelerator is presented, enabling on‐chip training, weight retention, and long‐term inference acceleration. It leverages a BEOL‐integrated CMO/HfOx ReRAM array with low‐voltage operation (<1.5 V), multi‐bit capability over 32 states, low programming noise (10 nS), and near‐ideal weight transfer.

Fluid inclusion and H–O–S isotope constraints on the genesis of the Ashawayi gold deposit, Southern Tianshan, Xinjiang, NW China

Frontiers in Earth Science
The Ashawayi gold deposit is situated in the eastern part of the Southern Tianshan Sb–Hg–Au metallogenic belt, a significant source of gold in China. This deposit exhibits typical disseminated mineralization controlled by faults or fractures.

Emplacement age and PGE geochemistry of lamprophyres in the Laowangzhai gold deposit, Yunnan, SW China

, 2001
Widely-distributed lamprophyres in the Laowangzhai gold deposit were associated closely with gold ores. Phlogopite 40Ar/39Ar dating suggests that the emplacement age of lampro-phyric magma ranges from (30.8 0.4) to (34.3 0.2) Ma, and gold ...

The early cretaceous Yangzhaiyu lode gold deposit, north China craton: A link between craton reactivation and gold veining

, 2012
The Yangzhaiyu gold deposit is one of numerous lode gold deposits in the Xiaoqinling district, southern margin of the North China Craton. Gold mineralization is hosted in Neoarchean to early Paleoproterozoic amphibolite facies metamorphic rocks and ...

Printed Integrated Logic Circuits Based on Chitosan‐Gated Organic Transistors for Future Edible Systems

Advanced Functional Materials, EarlyView.
Edible electronics needs integrated logic circuits for computation and control. This work presents a potentially edible printed chitosan‐gated transistor with a design optimized for integration in circuits. Its implementation in integrated logic gates and circuits operating at low voltage (0.7 V) is demonstrated, as well as the compatibility with an ...

The Pambula Gold-Deposits [PDF]

Quarterly Journal of the Geological Society of London, 1893
The Pambula Goldfield is situated in the parish of Yowaka, county of Auckland, in the south-eastern corner of New South Wales, and is about 11 miles north of Twofold Bay. Most so-called ‘practical’ miners, especially those accustomed to well-defined quartz-reefs, acknowledge that these deposits are quite different from anything they have ...

Composites of Shellac and Silver Nanowires as Flexible, Biobased, and Corrosion‐Resistant Transparent Conductive Electrodes

Advanced Functional Materials, EarlyView.
Shellac, a centuries‐old natural resin, is reimagined as a green material for flexible electronics. When combined with silver nanowires, shellac films deliver transparency, conductivity, and stability against humidity. These results position shellac as a sustainable alternative to synthetic polymers for transparent conductors in next‐generation ...
