Ionic Metal Poly(heptazine Imides) and Single‐Atoms Interplay: Engineered Stability and Performance for Photocatalysis, Photoelectrocatalysis and Organic Synthesis

open access: yesAdvanced Functional Materials, EarlyView.
Poly(heptazine) imides (PHIs), a crystalline carbon nitride subclass, intercalate metals to deliver high stability, tunable electronics, and efficient charge separation. These features enable solar‐driven applications such as hydrogen evolution, CO₂ reduction, and organic synthesis.

Fixed point theorem for Interpolative contraction of Suzuki type mappings in CAT (0) spaces

open access: yesResults in Control and Optimization
In this work, we obtained a fixed point theorems ω−ψ−interpolative Hardy–Rogers contraction, ω−ψ−interpolative Kannan contraction and ω−ψ−interpolative Reich–Rus–Ciric type contraction for Suzuki generalized non-expansive mappings in the context of ...

Cu‐Based MOF/TiO2 Composite Nanomaterials for Photocatalytic Hydrogen Generation and the Role of Copper

open access: yesAdvanced Functional Materials, EarlyView.
HKUST‐1/TiO2 composite materials show a very high photocatalytic hydrogen evolution rate which increases as a function of the irradiation time until reaching a plateau and even surpasses the performance of the 1%Pt/TiO2 material after three photocatalytic cycles.

Mg2+/Al3+ Co‐doped Li‐Rich Manganese‐Based Oxides for Boosting Rate Performance and Stability of Lithium‐Ion Batteries

open access: yesAdvanced Functional Materials, EarlyView.
The co‐doping strategy can effectively address the challenges associated with LRMOs cathode materials, providing a promising pathway for the development of high energy density and resilient cathode materials in the next‐generation lithium‐ion batteries. Abstract Lithium‐rich manganese‐based oxides (LRMOs) are promising cathode materials for lithium‐ion

On the Assouad-Nagata Dimension of CAT(0) Spaces

open access: yes, 2017
The Nagata dimension of a metric space X is the least integer n, such that for all r>0 there is a cover of X with sets whose diameter is bounded by cr and every set of diameter bounded by r does intersect at most n+1 of the sets of the cover. Here, c>0 is a constant independent of r.

Mixed‐Dimensional 0D‐DNA‐2D Heterostructures Beyond van der Waals: A DNA‐Templated Strategy for Optoelectronic Tunability

open access: yesAdvanced Functional Materials, EarlyView.
A two‐step DNA metallization process is presented for the modular assembly of metal sulfide nanoparticles (NPs) on MoS2, with nanoscale control over their separation and ability to concomitantly assemble different kind of NPs. This allowed to tailor the photoinduced electrical response of phototransistors to different wavelengths, according to the ...
