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.

Toughening mechanisms in novel nano-silica epoxy polymers [PDF]

open access: yes, 2007
A crosslinked epoxy polymer has been modified by the addition of nano-silica particles. The particles were introduced via a sol-gel technique which gave a very well dispersed phase of nanosilica particles which were about 20 nm in diameter.

Strong Lateral Confinement of Hydrophilic Silica Nanoparticles on Mg‐Al Layered Double Hydroxides Nanoflakes for Enhanced Thermal Properties

open access: yesAdvanced Materials Interfaces, EarlyView.
A nanostructured, naturally flame‐retardant, and non‐toxic inorganic composite is introduced, which is laterally associated with silica nanoparticles to induce the restacking of the LDH lamella structure, thereby serving as an efficient thermal insulator.

Morphology‐Controlled Silica Nanoparticle Coatings for Transparent Radiative Cooling

open access: yesAdvanced Materials Interfaces, EarlyView.
Transparent radiative cooling coatings are achieved by immobilizing solid and hollow silica spheres on glass. Particle morphology within sub‐monolayer coatings is shown to govern the trade‐off between visible and atmospheric window reflectance. Hollow‐sphere structures enable reduced thermal emission losses while preserving transparency, highlighting ...

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 ...

3D Printed Omniphobic Slippery Liquid Infused Porous Surfaces for Low Surface Tension Repellency

open access: yesAdvanced Materials Technologies, EarlyView.
A 3D printing strategy fabricates omniphobic slippery liquid‐infused porous structures with lubricant reservoirs and interconnected microchannels. A post‐printing surface treatment modifies the porous surface to ensure compatibility with the infused fluorinated lubricant.
