Pulsed DC Sputter Deposition of Stable Turbostratic Boron Nitride Thin Films

Advanced Materials Interfaces, EarlyView.
Boron nitride (BN) films are deposited by sputtering from a boron target. During deposition, a substrate bias voltage is applied between the plasma and the sample, which reduces excess boron in the film and enhances the crystallinity. This process prevents the formation of boric acid and ammonium borate hydrate.

Nanoporous Microelectrodes for Neural Electrophysiology Recordings in Organotypic Culture

Advanced Materials Technologies, EarlyView.
The highly porous microelectrodes have been designed and printed on culture membranes, allowing to record electrophysiological neural activity for rodent brain slices. To keep the biocompatible nanoporous structure, the microelectrodes and insulative layer are fabricated on the bottom of culture membranes with only small connector pads added on the top.

Tooth embedding medium influences the accuracy of electronic apex locator. [PDF]

Acta odontologica latinoamericana : AOL, 2013
This study evaluated the influence of tooth embedding media on the accuracy ofan electronic apex locator. The root canal length of 20 human mandibular canines was measured by inserting a 15 K-file into the root canal up to the apical foramen. The distance was measured with a digital caliper.

Scalable Layer‐by‐Layer Electrospray‐Assisted Interfacial Polymerization: Enabling Large‐Area Polyamide Membrane Fabrication

Advanced Materials Technologies, EarlyView.
We report a multi‐jet, layer‐by‐layer electrospray‐assisted interfacial polymerization (LBL‐EAIP) approach for the scalable fabrication of polyamide reverse osmosis (RO) membranes. The method enables precise control of polymerization, uniform polyamide coverage, and tunable polyamide film thickness, while delivering consistently high filtration ...

High‐Throughput Screening of REBCO Superconducting Thin Films Fabricated Via Combinatorial Inkjet Printing and TLAG Process

Advanced Materials Technologies, EarlyView.
A methodological framework is presented for combinatorial REBCO thin films fabricated by drop‐on‐demand inkjet printing with controlled Rare Earth composition gradients. Automated, synchrotron‐based, and local characterization techniques produce comprehensive property maps that correlate composition and TLAG process parameters with superconducting ...

Molecular Inks for the Development of Complex 3D In‐Mold Electronics

Advanced Materials Technologies, EarlyView.
Molecular inks (MINKs) enable the fabrication of thermoformed 3D circuits by decoupling the forming and metallization steps. Following thermoforming, intense pulsed‑light or thermal processing converts the patterned MINKs into complex 3D conductive tracks with improved stretchability and electrical performance, advancing low‑cost, high‑performance in ...
