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 ...

Advanced Functional Materials, EarlyView.For the first time, a highly sensitive electrochemical biosensor based on SiO2‐based hairy particles with a grafted PDMAEMA polymer brush containing a quantifiable and large amount of immobilized Laccase is reported. The fabricated biosensor exhibits a sensitivity of 0.14 A·m⁻¹, a limit of detection (LOD) of 0.1 µm, and a detection range of 0.3–750 µm,

Gold in iron oxide copper–gold deposits
Ore Geology Reviews, 2016 Abstract Iron oxide copper–gold (IOCG) deposits contain economic or anomalous gold, and the gold distribution is important both for its economic significance and ore genesis. However, the gold distribution in IOCG deposits and its controlling factors remain unclear.

The relation between Cu/Au ratio and formation depth of porphyry-style Cu-Au ± Mo deposits [PDF]
, 2018 Constraints on gold and copper ore grades in porphyry-style Cu-Au ± Mo deposits are re-examined, with particular emphasis on published fluid pressure and formation depth as indicated by fluid inclusion data and geological reconstruction.

Hydrothermal alteration and fluid pH in alkaline-hosted epithermal systems [PDF]
, 2017 Epithermal gold mineralisation is found in a wide compositional range of host lithologies, but despite the diversity the alteration mineral assemblages are often similar between deposits. Notable exceptions are those gold deposits hosted in alkaline host

Advanced Functional Materials, EarlyView.The dielectric properties of clays are studied on the level of individual monolayers and functional double stacks. The material breakdown characteristics and charge storage performance are analyzed. For illustration, a defined charge pattern representing a cuneiform character is produced, written into a microscopic clay tile, referencing the origins of
