Unlocking NIR‐II Photoluminescence in 2D Copper Tetrasilicate Nanosheets through Flame Spray Synthesis

Advanced Materials, EarlyView.
A flame‐spray‐pyrolysis method is presented to synthesize ultra‐bright CTS nanosheets with tunable NIR‐II emission. Achieving quantum yields up to 34%, these materials support high‐speed imaging and enable super‐resolution in vivo applications such as transcranial microcirculation mapping and macrophage tracking.

Does presence of a mid-ocean ridge enhance biomass and biodiversity? [PDF]

, 2013
In contrast to generally sparse biological communities in open-ocean settings, seamounts and ridges are perceived as areas of elevated productivity and biodiversity capable of supporting commercial fisheries.

Nanoarchitectonics of Metal–Organic Framework and Nanocellulose Composites for Multifunctional Environmental Remediation

Advanced Materials, EarlyView.
Nanoscale metal–organic frameworks (MOFs) and nanocellulose composites have significant potential for the multi‐functional remediation of the environment. This review focused on the synthesis strategies (in situ growth, ex situ growth, and other approaches), typical forms (aerogel, hydrogel, beads, and membrane), and applications in the removal of ...

Impact-generated hydrothermal circulation and metasomatism of the rochechouart astrobleme: mineralogy and major and trace element distribution [PDF]

, 2014
The energy released during a hypervelocity impact on Earth can generate high temperatures in the target rock. There are currently 170 known impact structures worldwide, of which over one-third contain fossil hydrothermal systems [1].

Idealised modelling of ocean circulation driven by conductive and hydrothermal fluxes at the seabed

Ocean Modelling, 2018
Geothermal heating is increasingly recognised as an important factor affecting ocean circulation, with modelling studies suggesting that this heat source could lead to first-order changes in the formation rate of Antarctic Bottom Water, as well as a significant warming effect in the abyssal ocean.

Copper Catalysts Inherit and Retain Precatalyst Morphology in Extended CO Electroreduction to n‐Propanol

Advanced Materials, EarlyView.
Flash Joule heating enables the formation of quenched Cu oxide precatalysts with intragrain‐in‐grain architectures. These hierarchical structures are inherited after electroreduction, suppressing reconstruction even at high current densities in an MEA cell.

Recent Advances in Reactive Microdroplets for Clean Water and Energy

Advanced Materials, EarlyView.
Reactive microdroplets enable precise and sustainable chemistry at small scales. This review explores their role as confined reactors and dynamic interfaces for synthesizing functional materials, fuels, and microdevices. It offers a critical perspective on how droplet‐based platforms can drive next‐generation technologies in clean energy, environmental

Anchoring Redox Mediator on COFs for Efficient Solar to Hydrogen Conversion

Advanced Materials, EarlyView.
In this work, Fe ions are first fixed on COFs skeleton to construct a novel 2D Z‐scheme heterojunction (BWO/Fe/TP1C). The cycling of Fe3+/Fe2+ significantly improves the electron transfer rate. In addition, the construction of 2D Z‐scheme heterojunction not only promotes the separation of photogenerated carriers but also ensures its high redox activity.
