Tin Oxide‐Anchored MXene Composites for Enhanced Hydrogen Evolution in Alkaline Media

open access: yesAdvanced Materials Interfaces, EarlyView.
The schematic illustrates a SnO2/MXene heterostructure for efficient hydrogen evolution. SnO2 nanoparticles are uniformly anchored on conductive MXene nanosheets, enhancing charge transfer and catalytic activity. The MXene substrate provides high electrical conductivity and abundant active sites, while SnO2 facilitates water adsorption and dissociation.

The selection of subcontractors: is price the major factor? [PDF]

open access: yes, 2007
The philosophy of ‘lowest price wins’ in the selection of subcontractors often leads to problems with quality of work and claims for further costs. Since Latham (1994), many models have offered selection methods that take account of a wide range of ...

Transducers Across Scales and Frequencies: A System‐Level Framework for Multiphysics Integration and Co‐Design

open access: yesAdvanced Materials Technologies, EarlyView.
Transducers convert physical signals into electrical and optical representations, yet each mechanism is bounded by intrinsic trade‐offs across bandwidth, sensitivity, speed, and energy. This review maps transduction mechanisms across physical scale and frequency, showing how heterogeneous integration and multiphysics co‐design transform isolated ...
