Understanding the Effects of Conductive Polymer Electrode Coating on Recorded Neural Signals

Advanced Healthcare Materials, EarlyView.
Conductive polymer coatings are widely explored to improve the quality of signals recorded with chronically implanted neural electrodes, offering enhanced biocompatibility along with reduced electrode impedance. Combining computational modelling and data from PEDOT:PTS coated and PtIr electrodes in rats, we show that improvements in signal quality with

Magnetocaloric effect in bamboo-grained Ni-Mn-Ga microwires over a wide working temperature interval

Materials & Design, 2020
Bamboo-grained Ni-Mn-Ga microwire is promising for achieving considerable magnetic-field-induced strain due to less neighboring grain constraints to the twin boundary motion.

Fabrication and electrical transport properties of embedded graphite microwires in a diamond matrix

, 2017
Micrometer width and nanometer thick wires with different shapes were produced $\approx 3~\upmu$m below the surface of a diamond crystal using a microbeam of He$^+$ ions with 1.8~MeV energy.

Study of the Negative Magneto-Resistance of Single Proton-Implanted Lithium-Doped ZnO Microwires [PDF]

, 2015
The magneto-transport properties of single proton-implanted ZnO and of Li(7\%)-doped ZnO microwires have been studied. The as-grown microwires were highly insulating and not magnetic.

Magnetotransport properties of iron microwires fabricated by focused electron beam induced autocatalytic growth

, 2011
We have prepared iron microwires in a combination of focused electron beam induced deposition (FEBID) and autocatalytic growth from the iron pentacarbonyl, Fe(CO)5, precursor gas under UHV conditions. The electrical transport properties of the microwires

Low temperature magnetic behaviour of glass-covered magnetic microwires with gradient nanocrystalline microstructure [PDF]

, 2014
Slow nanocrystallization driving dynamics can be affected by the combination of two factors: sample residual stresses and sample geometry. This effect is evidenced at the initial stages of nanocrystallization of amorphous CoFeSiBCuNb magnetic microwires.

Thermal Processing Creates Water‐Stable PEDOT:PSS Films for Bioelectronics

Advanced Materials, Volume 37, Issue 13, April 2, 2025.
Instead of using chemical cross–linkers, it is shown that PEDOT:PSS thin films for bioelectronics become water‐stable after a simple heat treatment. The heat treatment is compatible with a range of rigid and elastomeric substrates and films are stable in vivo for >20 days.

Opportunities of Semiconducting Oxide Nanostructures as Advanced Luminescent Materials in Photonics

Advanced 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
