Swift heavy ion irradiation puts InGaN/GaN multi-quantum wells on the track for efficient green light emission

open access: yesNano Trends
InN and InGaN/GaN multi-quantum wells (MQWs) were subjected to Swift Heavy Ion (SHI) irradiation. Ion track formation was studied using transmission electron microscopy in both plane view and cross-sectional modes.

Safeguarding the Photoluminescence of Silver Sulfide Nanocrystals in Biological Environments via Silica Shielding

open access: yesSmall, EarlyView.
Interactions with biomolecules can alter the photoluminescence of Ag2S nanocrystals, undermining near‐infrared imaging and thermometry. Incorporation into dendritic silica minimizes these interactions and preserves emission intensity, spectral response, and lifetime in plasma and whole blood. This shielding enables more reliable imaging and temperature

Nanopatterning by Swift Heavy Ions

open access: yes, 2006
Today, the dominating way of patterning nanosystems is by irradiation-based lithography (e-beam, DUV, EUV, and ions). Compared to the other irradiations, ion tracks created by swift heavy ions in matter give the highest contrast, and its inelastic scattering facilitate minute widening and high aspect ratios (up to several thousands).

Impact of dicarboxystilbene impurities on the properties of swift heavy ion latent tracks in PET films

open access: yesOptical Materials: X
We present a new hypothesis and supporting experimental evidence about the essential role played by small impurities of dicarboxystilbene in the process of UV treatment of PET films irradiated with swift heavy ions (SHI). This treatment both forms highly

Nonthermal plasma approaches for combating implant‐associated infections: A compendious review

open access: yesVIEW, EarlyView.
Implant‐associated infections pose serious clinical challenges. Non‐thermal plasma (NTP) modifications overcome this bottleneck in distinct ways relative to traditional sterilization methods. Gas‐phase plasmas generate highly energetic species, UV radiation and reactive oxygen/nitrogen species (RONS), which alter the implant surface properties.

On the Conceptual Overstretch of Weaponized Interdependence in Lithium and Rare‐Earth Element Markets

open access: yesGlobal Policy, EarlyView.
ABSTRACT This paper critically examines the conceptual overstretch of weaponized interdependence (WI) in analyses of China's dominance over lithium and rare‐earth element (REE) markets. Although WI has become a central framework for interpreting EU–China economic relations, its application to raw materials often extends beyond the theory's original ...
