Phase composition and transformations in magnetron-sputtered (Al,V)2O3 coatings

, 2019
Coatings of (Al1-xVx)2O3, with x ranging from 0 to 1, were deposited by pulsed DC reactive sputter deposition on Si(100) at a temperature of 550 {\deg}C. XRD showed three different crystal structures depending on V-metal fraction in the coating: {\alpha}-

Structure and wear mechanisms of nano-structured TiAlCN/VCN multilayer coatings [PDF]

, 2007
Dry sliding wear of transition metal nitride coatings usually results in a dense and strongly adhered tribofilm on the worn surface. This paper presents detailed electron microscopy and Raman spectroscopy characterizations of the microstructure, a newly ...

Thermally Modulated Metasurface Sensor for Dynamic and Time‐Resolved Isolation of Extracellular Vesicles

Advanced Materials, EarlyView.
A thermally adaptive plasmonic metasurface, functionalized with poly(N‐isopropylacrylamide) (PNIPAM) and anti‐CD63 antibodies, enables precise, on‐demand capture and release of extracellular vesicles (EVs). Delivering high recovery, improved purity, and intact vesicle structure, the platform offers a versatile, label‐free solution for real‐time EV ...

Leaftronics: Bio‐Fractal Scaffolds From Leaf Venation for Low‐Waste Electronics

Advanced Materials, EarlyView.
“Leaftronics” transforms naturally evolved leaf venation into quasi‐fractal scaffolds for sustainable electronics. Polymer‐infiltrated leaf skeletons can be used to fabricate ultra‐smooth, reflow‐ and thin‐film‐compatible decomposable substrates, while making the same lignocellulose networks conducting results in flexible transparent electrodes.

Enhancing Interfacial Charge Transport in Gold Nanoparticle@Polyaniline Hybrids via N‐Heterocyclic Carbene Linkers

Angewandte Chemie, EarlyView.
An amino‐functionalized NHC‐Au complex is employed as a conductive molecular linker to couple large Au NPs with PANI, yielding Au NP@NHC‐PANI hybrids with an electronically well‐defined interface. SAMs of these hybrids reveal enhanced charge transport compared with Au NP@PANI.
