Shaping Matter with Acoustic Waves: From Particles to Functional Structures

open access: yesAdvanced Functional Materials, EarlyView.
Acoustic‐directed assembly is reviewed as a materials‐oriented strategy for organizing particles, polymers, metals, and biological systems into functional structures. The review distinguishes reversible manipulation from permanent structure formation through medium fixation, particle fixation, and in situ material generation, highlighting routes toward

Microscopic Origin of Temperature‐Dependent Anisotropic Heat Transport in Ultrawide‐Bandgap Rutile GeO2

open access: yesAdvanced Functional Materials, EarlyView.
Rutile GeO2${\rm GeO}_{2}$ exhibits orientation‐dependent heat transport with temperature‐dependent anisotropy, showing higher cross‐plane thermal conductivity along [001] than along the equivalent in‐plane [100] and [010] directions. Temperature‐dependent TDTR measurements and first‐principles phonon calculations identify the microscopic phonon ...

Vers le Sud : le voyage de Johann Georg von Dillis à travers la France, la Suisse et l'Italie en 1806

open access: yesRIHA Journal, 2011
Southern France, and Provence in particular, started to lure painters as early as in the 18th century, first and foremost French ones, and then increasingly foreign painters, notably the German landscapist Johann Georg von Dillis. In 1806, he undertook a

Bacteria‐Responsive Nanostructured Drug Delivery Systems for Targeted Antimicrobial Therapy

open access: yesAdvanced Materials, EarlyView.
Bacteria‐responsive nanocarriers are designed to release antimicrobials only in the presence of infection‐specific cues. This selective activation ensures drug release precisely at the site of infection, avoiding premature or indiscriminate release, and enhancing efficacy.

When travel is a challenge: Travel medicine and the ‘dis-abled’ traveller

open access: yesTravel Medicine and Infectious Disease, 2018
Travellers with recognised disabilities or the dis-ability to function as required during a trip have been overlooked in the travel medicine literature. This paper provides a starting point for further discussion and research into this neglected traveller population.

Opportunities of Semiconducting Oxide Nanostructures as Advanced Luminescent Materials in Photonics

open access: yesAdvanced Materials, EarlyView.
The review discusses the challenges of wide and ultrawide bandgap semiconducting oxides as a suitable material platform for photonics. They offer great versatility in terms of tuning microstructure, native defects, doping, anisotropy, and micro‐ and nano‐structuring. The review focuses on their light emission, light‐confinement in optical cavities, and

“Writing is travelling unfolding it’s own landscape.” A discussion with Breyten Breytenbach on A Veil of Footsteps

open access: yesTydskrif vir Letterkunde, 2017
This discussion of A Veil of Footsteps (Memoir of a nomadic fictional character) resulted from my reading of the manuscript – initially entitled Word Bird (On the peripatetic art of writing an I) – in August and September 2007.

Self‐Assembled Inorganic Nanomembrane Tubes: Rolled‐Up Piezoelectrics for Microacoustic Wave‐Based Actuators and Sensors

open access: yesAdvanced Materials, EarlyView.
This study demonstrates a self‐assembly process to generate free‐standing piezoelectric nanomembranes, forming ultracompact microtubular acoustic wave sensors and actuators. The miniaturized 3D piezoelectric platform reported in this work can be applied in telecommunication, energy harvesting, and acoustofluidics. Moreover, the 3D self‐assembly can add

Flexible Dielectric Acoustic Resonator Patch for Tissue Regeneration

open access: yesAdvanced Materials, EarlyView.
A flexible dielectric acoustic resonator patch enables MHz‐range ultrasound generation through resonance amplification without using piezoelectric materials. Conformal integration on a curved substrate allows efficient acoustic delivery to tissue‐mimicking environments.
