Combustion synthesis of ceramic and metal-matrix composites [PDF]

open access: yes
Combustion synthesis or self-propagating high temperature synthesis (SHS) is effected by heating a reactant mixture, to above the ignition temperature (Tig) whereupon an exothermic reaction is initiated which produces a maximum or combustion temperature,

Synthesis and methane cracking activity of a silicon nitride supported vanadium nitride nanoparticle composite [PDF]

open access: yes, 2017
The co-ammonolysis of V(NMe2)4 and Si(NHMe)4 with ammonia in THF and in the presence of ammonium triflate ([NH4][CF3SO3]) leads to the formation of monolithic gels.

Plasmonic Nanomachines: Creating Local Potential Gradients and Motions

open access: yesAdvanced Materials, EarlyView.
Plasmonic nanomachines can generate optical, thermal, and chemical potential gradients to drive directional rectilinear, rotational, and twisting motions at the nanometer scale. The integration of multimodal plasmonic forces with functional materials and programmed structural distortions enables precise spatiotemporal actuation, thereby providing a ...

Integrating ZnO/Ag2O@g‐C3N4‐Based Nanocomposites Into a Carrageenan Matrix to Efficiently Remove Heavy Metals From Water

open access: yesAdvanced Materials Interfaces, EarlyView.
ABSTRACT This research focused on characterizing graphitic carbon nitride (g‐C3N4) nanocomposites incorporated with ZnO and Ag2O nanoparticles, and carrageenan to remove heavy metals. The ZnO/Ag2O@ g‐C3N4 and ZnO/Ag2O/g‐C3N4@Carr nanocomposites demonstrated thermal stability of 97.40% (108.81°C) and 82.80% (188.99°C) for TGA.

Light‐Programmable Interfaces: From Molecular Photoswitching to Adaptive Membrane Separations

open access: yesAdvanced Materials Interfaces, EarlyView.
This review advances an interface‐centered framework for light‐responsive membranes, linking molecular photoswitches (azobenzene (AZO), spiropyran (SP), diarylethene (DAE), donor–acceptor Stenhouse adducts (DASA), photoacid) to integration strategies in polymeric, porous, self‐assembled, and mixed‐matrix systems.

Mass Spectrometric Investigation of the Influence of Water Vapour and Oxygen on Gas‐Phase Reactions of Aluminium Acetylacetonate

open access: yesAdvanced Materials Interfaces, EarlyView.
The gas‐phase decomposition of Al(acac)3 is investigated under inert, oxygen, and water‐containing conditions. Water is found to promote selective ligand removal and suppress hydrocarbon formation, while oxygen induces faster, less selective decomposition pathways.
