DNA‐Templated 2D Heterostructures as Phototriggered Dynamic Nanohybrids: From Releasing Molecular Loads to Controlling Enzyme Biocatalytic Function

open access: yesAdvanced Functional Materials, EarlyView.
DNA strands are employed both as dynamic linkers and nanoscale templates for the integration of Ag2S nanoparticles on MoS2, which in turn imparted photothermal responsiveness; this feature permits the selective cargo (fluorophore, quantum dots or an enzyme) release from the MoS2 surface in response to local heat induced by light irradiation.

Ferroelectricity in Antiferromagnetic Wurtzite Nitrides

open access: yesAdvanced Functional Materials, EarlyView.
We establish MnSiN2${\rm MnSiN}_2$ and MnGeN2${\rm MnGeN}_2$ as aristotypes of a new multiferroic wurtzite family that simultaneously exhibits ferroelectricity and antiferromagnetism with altermagnetic spin splitting. By strategically substituting alkaline‐earth metals, we predict new materials with coexisting switchable polarization, spin texture, and

Interlayer Expansion of Bulk MoS2 via Top‐Down Organic Pillaring Enables Tunable Li+ Intercalation and Controlled Solvent Co‐Intercalation

open access: yesAdvanced Functional Materials, EarlyView.
Top‐down organic pillaring expands the interlayer spacing of bulk‐sized MoS2 particles while preserving the bulk morphology. Operando X‐ray diffraction and electrochemical dilatometry show that MoS2‐bulk undergoes solvent co‐intercalation in diglyme electrolyte, causing large structural expansion, while pillared, expanded MoS2 suppresses solvent uptake

Ecological Restoration in Conservation Units

open access: yes, 2015
Forest ecosystems have rapidly been transformed into areas for the occupation of the human population and for economic purposes [1]. Rainforests distributed around the planet have been cleared because of a complex set of factors, which vary according to the characteris‐ tics of each region [2]. Among the factors are deforestation for alternative use of
