Raman Spectroscopic Identification of Oxide Phases in a Corroded MgO–Steel Composite Anode Used in Aluminum Molten Salt Electrolysis

open access: yesAdvanced Engineering Materials, EarlyView.
Micro‐Raman spectroscopy is applied to characterize corrosion products in a recycled‐based MgO–316L steel composite anode after molten salt electrolysis. A depth‐dependent Fe–O/Fe–Al–O layer sequence of magnetite, hercynite, and an Al‐doped magnetite transition zone is identified.

Photocatalytic Water Splitting on the Lunar Surface: Prospects for In Situ Resource Utilization

open access: yesAdvanced Materials Interfaces, EarlyView.
Water has been found in craters on the moon nearby locations which are illuminated >80% of the time. Photocatalysis uses energy from sunlight to drive chemical reactions such as water splitting to produce oxygen and hydrogen. It is a scalable technology that requires lighter equipment and utilizes resources available on the moon. ABSTRACT The discovery

Effect of Surface‐Lubricant Compatibility on Bubble Formation in Lubricant‐Infused Surfaces

open access: yesAdvanced Materials Interfaces, EarlyView.
Lubricant‐infused surfaces reduce drag partly through bubbles that form when lubricant depletes. Using laser‐textured steel infused with silicone oil, we show that microbubble nucleation occurs even on surfaces fully wetted by the lubricant, regardless of chemistry.

New Directions in Focused Ion Beam Induced Deposition for the Nanoprinting of Functional 3D Heterostructures

open access: yesAdvanced Materials Technologies, EarlyView.
Here, it is shown that focused ion beam induced deposition (FIBID) using helium and neon ions enables advanced high‐resolution 3D nanoprinting achieving precise multimaterial architectures and engineered internal voids. Thus, FIBID with finely focused noble gas ion species is presented as a unique platform for designing functional nanomaterials for ...

Mantle magma-thermofluidodynamic and intracrustal granitoid-hydrothermal-metasomatic auriferous systems [PDF]

open access: yes, 2007
Contents of typical models of formation of abyssal and intra-core ore-forming systems are discussed. As it has been already marked, the interaction between core and mantle ore-forming systems occurred at formation of large and unique golden-ore deposits.

Bioinspired Microreactor for Iodide Adsorption and Photooxidation Recovery

open access: yesAdvanced Science, EarlyView.
A bioinspired micro‐ionic‐reactor based on porous organic polymer (MIR‐POP) integrates rapid iodide capture with in situ photooxidative conversion, achieving record uptake capacity and high uptake efficiencies in simulated mining wastewater and natural brine. This bioinspired microreactor strategy offers a new avenue for sustainable iodine recovery and
