MOF-Derived Defective CoO Nanosheets in Carbon Nitride Nanocomposites for CO Photoreduction and H Production.

In photocatalysis, especially in CO reduction and H production, the development of multicomponent nanomaterials provides great opportunities to tune many critical parameters toward increased activity. This work reports the development of tunable organic/inorganic heterojunctions comprised of cobalt oxides (CoO) of varying morphology and modified carbon nitride (CN), targeting on optimizing their response under UV-visible irradiation. MOF structures were used as precursors for the synthesis of CoO.

Photocatalytically Active Graphitic Carbon Nitride as an Effective and Safe 2D Material for In Vitro and In Vivo Photodynamic Therapy.

Thanks to its photocatalytic property, graphitic carbon nitride (g-C N ) is a promising candidate in various applications including nanomedicine. However, studies focusing on the suitability of g-C N for cancer therapy are very limited and possible underlying molecular mechanisms are unknown. Here, it is demonstrated that photoexcitation of g-C N can be used effectively in photodynamic therapy, without using any other carrier or additional photosensitizer.

The Effect of Materials Architecture in TiO /MOF Composites on CO Photoreduction and Charge Transfer.

CO photoreduction to C /C energized molecules is a key reaction of solar fuel technologies. Building heterojunctions can enhance photocatalysts performance, by facilitating charge transfer between two heterojunction phases. The material parameters that control this charge transfer remain unclear.

Can application and transfer of strategy be observed in low visibility condition?

It has been long assumed that cognitive control processes can only be applied on consciously visible stimuli, but empirical evidence is contradictory. In the present study, we investigated strategic adaptation to conflict both in unmasked and in low-visibility masked trials. Using a paradigm derived from the Stroop task, we studied the application of strategies, but also the transfer of a strategy developed in unmasked trials to masked trials, and the trial-to-trial dynamics of strategic processing.

Layer-by-Layer Photocatalytic Assembly for Solar Light-Activated Self-Decontaminating Textiles.

Novel photocatalytic nanomaterials that can be used to functionalize textiles, conferring to them efficient solar-light-activated properties for the decontamination of toxic and lethal agents, are described. Textiles functionalized with one-dimensional (1D) SnS-based nanomaterials were used for photocatalytic applications for the first time. We showed that 1D SnS/TiO nanocomposites can be easily and strongly affixed onto textiles using the layer-by-layer deposition method.
