Atomically Dispersed Copper Electrocatalysts with Proton‐feeding Centers for Efficient Ammonia Synthesis by Nitrate Electroreduction

open access: yesAdvanced Functional Materials, EarlyView.
Rationally‐designed advanced carbon‐based single‐atom catalysts with isolated CuN2O2 active sites anchored in N,O‐doped porous carbon facilitate water dissociation and nitrate reduction, accelerating proton supply for efficient electrosynthesis of ammonia.

Biomass Native Structure Into Functional Carbon‐Based Catalysts for Fenton‐Like Reactions

open access: yesAdvanced Functional Materials, EarlyView.
This study indicates that eight biomasses with 2D flaky and 1D acicular structures influence surface O types, morphology, defects, N doping, sp2 C, and Co nanoparticles loading in three series of carbon, N‐doped carbon, and cobalt/graphitic carbon. This work identifies how these structural factors impact catalytic pathways, enhancing selective electron

Half‐Century Ammonia Emissions From Agricultural Systems in Southern Asia: Magnitude, Spatiotemporal Patterns, and Implications for Human Health

open access: yesGeoHealth, 2018
Much concern has been raised about the increasing threat to air quality and human health due to ammonia (NH3) emissions from agricultural systems, which is associated with the enrichment of reactive nitrogen (N) in southern Asia (SA), home of more than ...

3D Printing of Functional Mesoporous Silica Monoliths with Embedded Metal and MOF Components

open access: yesAdvanced Functional Materials, EarlyView.
This article presents the development of silica nanocage‐based nano‐inks tailored for digital light processing 3D printing, enabling automated additive manufacturing of mesoporous monoliths. Novel strategies for incorporating metal sites and inducing in situ growth of metal‐organic frameworks are introduced.

Process for the preparation of fluorine containing crosslinked elastomeric polytriazine and product so produced [PDF]

open access: yes, 1980
Crosslinking elastomeric polytriazines are prepared by a 4 step procedure which consists of (1) forming a poly(imidoylamidine) by the reaction, under reflux conditions, of anhydrous ammonia with certain perfluorinated alkyl or alkylether dinitriles; (2 ...
