Stoichiometry‐Programmed MXenes via Precursor Engineering for High‐Performance EMI Shielding and Energy Storage

open access: yesAdvanced Materials, EarlyView.
Precursor carbon stoichiometry programs internal strain and oxygen substitution in Ti3AlCxO2‐x, deterministically switching Ti3CxO2‐xTz MXenes between highly aligned 2D nanosheets and spontaneous 1D nanoscrolls. This synthesis‐stage architecture control enables ultrathin X/W‐band EMI shielding with outstanding mass‐normalized performance and bending ...

Unpacking the provision of the industrial commons in Industry 4.0 cluster

open access: yesEconomics and Business Review, 2019
This paper argues that provision of industrial commons (IC), might be considered as a crucial factor of a cluster’s attractiveness in digital transformation, e.g. in Industry 4.0 (I4.0) time.

Wafer‐Scale 2D High‐Entropy Transition Metal Dichalcogenide Thin‐Film Catalysts for Efficient and Durable Photoelectrochemical Hydrogen Production

open access: yesAdvanced Materials, EarlyView.
A wafer‐scale 2D high‐entropy (MoWTaNbRu)S2 thin‐film catalyst with a distorted 1T phase integrated onto p‐Si photocathode is designed for highly efficient and durable photoelectrochemical hydrogen evolution reaction. The high‐entropy effect in layered transition metal dichalcogenides optimizes hydrogen adsorption energetics, accelerates photogenerated

Characterization and Antimicrobial Activity of Hafnium Nanostructures Fabricated by Physical Vapor Deposition Through a Colloidal Mask

open access: yesAdvanced Materials Interfaces, EarlyView.
We generate hafnium nanostructures by first depositing polystyrene particles of varying diameter followed by physical vapour deposition of hafnium thin films. The resultant structure shows a kill‐on‐contact effect against both Gram‐negative Escherichia coli and Gram‐positive Staphylococcus aureus.
