Strong 3p -T1u Hybridization in Ar@C60 [PDF]

, 2010
Multilayers of fullerenes with and without endohedral Ar units, C60 and Ar@C60, were investigated by photoemission and density functional theory. The stoichiometry and the endohedral nature of Ar is checked by x-ray photoelectron spectroscopy and x-ray ...

Metal/Metal Carbide Catalyst of Growth of Single-Walled Carbon Nanotubes: New Examples of Filling Single-Walled Carbon Nanotubes

Materials Proceedings, 2023
In this work, I filled single-walled carbon nanotubes (SWCNTs) with nickelocene and cobaltocene molecules. I investigated the inner growth of carbon nanotubes on metallic and metal carbide catalysts.

Single-Layer Graphene/Germanium Interface Representing a Schottky Junction Studied by Photoelectron Spectroscopy

Nanomaterials, 2023
We investigated the interfacial electronic structure of the bidimensional interface of single-layer graphene on a germanium substrate. The procedure followed a well-established approach using ultraviolet (UPS) and X-ray (XPS) photoelectron spectroscopy ...

Remarkable thermal stability of BF3-doped polyaniline

, 2003
We show that the recently synthesized BF3-doped polyaniline (PANI) exhibits remarkable stability against thermal ageing. Unlike the protonated PANI, which shows rapid degradation of the conductivity on heating in air, BF3-doped PANI shows more than an ...

Innovative Processing of Compacted Waste Aluminum Alloy Powders via Controlled Remelting and Solidification

Advanced Engineering Materials, EarlyView.
This study demonstrates an efficient recycling route for out‐of‐spec AlSi10Mg atomized powders through compaction and arc remelting followed by suction casting. By correlating compaction load, cooling rate, and resulting microstructure, we show that intermediate pressures (50–80 kN) and rapid cooling refine dendrites, reduce porosity, and enhance ...
