Substrate‐Tight Graphene Transmembrane‐nanofluidic Devices

open access: yesSmall, EarlyView.
This study demonstrates that the covalent coupling of a pyrene layer to a silicon nitride substrate using silane and peptide chemistry increases the adhesion of graphene to the substrate and prevents the delamination of graphene. 76.2% of the devices with free‐standing graphene are successful devices for ion transport measurement in 0.1 M HCl ...

Formation Mechanism of BN Flakes on MWCNTs

open access: yesSmall, EarlyView.
This work presents a novel heterostructured h‐BN flake‐coating on multi‐wall carbon nanotubes synthesized via CVD. It details structural characterization supported by molecular dynamics simulations. The mechanism of BN flake formation, stress‐induced buckling, and van der Waals heterostructure design is discussed, highlighting applications in thermal ...

Surface Engineering of Ti3C2Tx MXenes via Silanol Functionalization for Improved Electrochemical Performance

open access: yesSmall, EarlyView.
This study explores the covalent functionalization of Ti3C2Tx using 5,5′‐bis(triisopropoxysilyl)‐2,2′‐bipyridine in different solvents, revealing that only m‐xylene enables effective covalent bonding, ensuring structural stability and preventing layer swelling.

Comunidad cristiana, comunidad iniciática

open access: yes, 2015
En la nueva etapa evangelizadora en la que ha entrado la Iglesia, la iniciación cristiana se ha convertido en el referente fundamental de su acción catequizadora. La catequesis inicia en la fe iniciando en la vida eclesial; es decir, iniciando en la experiencia viva que la comunidad cristiana tiene del misterio trinitario de comunión que se ha revelado

Temporal dynamics in functional fruit traits of native and invasive fleshy fruited plants in subtropical Andean forests

open access: yesFunctional Ecology, EarlyView.
Read the free Plain Language Summary for this article on the Journal blog. Abstract Fruits encompass the energetic and material flow between both interacting parties in frugivore‐mediated seed dispersal. Since fruit traits matter in frugivores' foraging decisions, the temporal dynamics of fruit traits might influence interaction outcomes.

Scaling from microsite to landscape to resolve litter decomposition dynamics in globally extensive drylands

open access: yesFunctional Ecology, EarlyView.
Read the free Plain Language Summary for this article on the Journal blog. Abstract Decomposition is the transformation of dead organic matter into its inorganic constituents. In most biomes, decomposition rates can be accurately predicted with simple mathematical models, but these models have long under‐predicted decomposition in globally extensive ...
