Fast and Sensitive Detection of Paramagnetic Species Using Coupled Charge and Spin Dynamics in Strongly Fluorescent Nanodiamonds

Sensing of a few unpaired electron spins, such as in metal ions and radicals, is a useful but difficult task in nanoscale physics, biology, and chemistry. Single negatively charged nitrogen-vacancy (NV-) centers in diamond offer high sensitivity and spatia ...

Self-Assembled Nanomicelles as MRI Blood-Pool Contrast Agent

Lothar Helm, Anne-Sophie Chauvin, Vassily Vorobiev

Gadolinium‐loaded nanomicelles show promise as future magnetic resonance imaging (MRI) contrast agents (CAs). Their increased size and high gadolinium (Gd) loading gives them an edge in proton relaxivity over smaller molecular Gd‐complexes. Their size and ...

Nanoionics Phenomena and Devices with Oxide Thin Films

Mahmoud Hadad

The number of studies on solid state ionic thin films (Nanoionics) has increased dramatically over last decades due to their high potential in micro and nanoscale technologies. Micro solid oxide fuel cells (micro-SOFC), and resistive switching memories (Re ...

Micro-solid state energy conversion membranes: influence of doping and strain on oxygen ion transport and near order for electrolytes

Paul Muralt

Enhancing the efficiency of micro-energy conversion devices through engineering of the structure-transport relationship is a prerequisite toward next generation micro-electrolysers and fuel cells. Here, oxygen ion conducting free-standing thin films are ke ...

Key-features in processing and microstructure for achieving giant electrostriction in gadolinium doped ceria thin films

Paul Muralt, Silviu Cosmin Sandu, Mahmoud Hadad, Husnain Ashraf

Gadolinium doped ceria is a well-known oxygen ion conduction material for solid fuel cell electrolytes. With its centrosymmetric average lattice and relatively low bulk dielectric constant it does not look interesting for electromechanical applications. Ho ...
