In this study, we have synthesized Ti(1-x)SmxO2 (x = 0–20%) nanocomposites by adopting an aqueous sol-gel route. A two or multi-phase mixture of titania and samarium oxide could be expected as samarium added >5% may exceed ...

Strained superlattices (SSLs) are typically found inside the p-n junction area of semiconductor devices and consist of very thin alternating layers of different material. There exists a small lattice mismatch between these ...

Nickel (Ni) foam-based symmetric/asymmetric electrochemical supercapacitors benefit from a randomly 3D structured porous geometry that functions as an active material support and as a current collector. The surface composition ...

Noble-metal nanoparticles size and packing density are critical for sensitive surface-enhanced Raman scattering (SERS) and controlled preparation of such films required to achieve reproducibility. Provided that they are ...

Analysis of the cellular response to piezoelectric materials has been driven by the discovery that many tissue components exhibit piezoelectric behavior ex vivo. In particular, polyvinylidene fluoride and the trifluoroethylene ...

Optical properties of metal nanostructures, governed by the so-called localised surface plasmon resonance(LSPR) effects,have envoked intensive investigations in recent times owing to their fundamental nature and potential ...

Soft exoskeletons apply compressive forces at the limbs via connection cuffs to actuate movement or stabilise joints. To avoid excessive mechanical loading, the interface with the wearer's body needs to be carefully designed. ...

The stability of typical vanadium flowbattery (VFB) catholytes with respect to precipitation of V2O5 was investigated at temperatures in the range 30–60◦C. In all cases a precipitate formed after an induction time, which ...

Colloidal carbon spheres were synthesized by the carbonization of squalane, a nonvolatile hydrocarbon solvent, in supercritical carbon dioxide. Precise pressure modulation of the fluid medium led to size controlled growth ...

Irish students’ interest and enjoyment of science deteriorates as they progress through formal education and subsequently enrolments in the physical sciences at second and third level education are low. Research in science ...
