Nanometer-Scale Lateral p–n Junctions in Graphene/α-RuCl3 Heterostructures
(American Chemical Society, 2022)
[EN] The ability to create nanometer-scale lateral p-n junctions is essential for the next generation of two-dimensional (2D) devices. Using the charge-transfer heterostructure graphene/alpha-RuCl3, we realize nanoscale ...
Nanostructural Organization of Thin Films Prepared by Sequential Dip-Coating Deposition of Poly(Butylene Succinate), Poly(ε-Caprolactone) and Their Copolyesters (PBS-ran-PCL)
(Elsevier, 2021-06-04)
In this work, we prepare and characterize multiphasic thin films containing poly(epsilon-caprolactone), PCL, poly (butylene succinate), PBS, and a poly (butylene succinate-ran-epsilon-caprolactone) (PBS-ran-PCL) random ...
Kinetics of NH3 Desorption and Diffusion on Pt: Implications for the Ostwald Process.
(American Chemical Society, 2021-10-21)
We report accurate time-resolved measurements of NH3 desorption from Pt(111) and Pt(332) and use these results to determine elementary rate constants for desorption from steps, from (111) terrace sites and for diffusion ...
Synthesis, Structure, Crystallization and Mechanical Properties of Isodimorphic PBS-ran-PCL Copolyesters
(MDPI, 2021-07-09)
Isodimorphic behavior is determined by partial inclusion of comonomer segments within the crystalline structure and arises from the comparatively similar repeating chain units of the parental homopolymers. Isodimorphic ...
Effect of the valence state on the band magnetocrystalline anisotropy in two-dimensional rare-earth/noble-metal compounds
(American Physical Society, 2022)
[EN] In intermetallic compounds with zero orbital momentum (L = 0) the magnetic anisotropy and the electronic band structure are interconnected. Here, we investigate this connection in divalent Eu and trivalent Gd intermetallic ...
Reducing Passive Drug Diffusion from Electrophoretic DrugDelivery Devices through Co-Ion Engineering
(Wiley, 2021-06)
Implantable electrophoretic drug delivery devices have shown promise for applications ranging from treating pathologies such as epilepsy and cancer to regulating plant physiology. Upon applying a voltage, the devices ...
Metal–Polymer Heterojunction in Colloidal-Phase Plasmonic Catalysis
(American Chemical Society, 2022-03-03)
[EN] Plasmonic catalysis in the colloidal phase requires robust surface ligands that prevent particles from aggregation in adverse chemical environments and allow carrier flow from reagents to nanoparticles. This work ...
3D Printable and Biocompatible Iongels for Body Sensor Applications
(Wiley, 2021-08)
Soft-ionic materials with biocompatibility and 3D printability are needed to develop next-generation devices to interface between electronic and biological signals. Herein, thermoreversible and biocompatible ionic liquid ...
Theory-guided enhancement of CO2 reduction to ethanol on Ag-Cu tandem catalysts via particle-size effects
(ACS, 2021-10-18)
In the CO2 reduction reaction, the design of electrocatalysts that selectively promote alcohols over hydrocarbons (e.g., ethanol over ethylene) hinges on the understanding of the pathways and specific sites that forms ...
Elucidating the Facet-dependent Selectivity for CO2 Electroreduction to Ethanol of Cu-Ag Tandem Catalysts
(ACS, 2021-04-07)
Despite being desirable high-value products of the electrochemical CO2 reduction reaction (CO2RR), alcohols are still obtained with lower selectivity compared to hydrocarbons and the reaction pathways leading to their ...
