X‐ray photoelectron spectroscopy and tribology studies of annealed fullerene‐like WS₂ nanoparticles

Abstract

Organic conducting polymers can be synthesized inside the pores of a track‐etch membrane, and the resulting hollow tubules are shown to have enhanced electrical properties compared to their corresponding bulk materials. The polymerization of monomers (e.g., pyrrole, thiophenes) inside the confined space of these pores, combined with electrostatic interaction, ensures the alignment of the organic polymers on the interior, leading to higher conductivity. The application of these conducting tubes in the development of amperometric glucose sensors is discussed. Due to the special properties of conducting polymers inside a track‐etch membrane, biosensors with a unique electron‐transfer mechanism have been developed.

Mechanism of Action of WS2 Lubricant Nanoadditives in High-Pressure Contacts

“…12). The main signals are for W 6? , specific to WO 3 (35.6 eV) and for W 0 (31.2 eV) [25,33,34]. The only exception was in the unsputtered layer, where W was found at 31.5 eV.…”

Lightweight and High-Performance Microwave Absorber Based on 2D WS2–RGO Heterostructures

“…In addition, a solvothermalsynthesized MoS 2 /rGO heterostructure nanosheet absorber has been reported to exhibit a maximum RL of − 31.57 dB at a thickness of 2.5 mm [39]. Similarly, WS 2 -rGO heterostructure nanosheets could also be synthesized by the solvothermal method [34]; these nanosheets have been used for electrocatalytic hydrogen evolution [40][41][42][43]. However, the dielectric loss and microwave absorption properties of WS 2 -rGO systems have not been studied.…”

“…The second component at 169.3 eV (Figure a) indicates that the surface of pristine NT‐WS 2 contains a certain amount of SO 4 2− (about 17 at.%. of all superficial sulfur) . Obviously, it is formed due to prolonged contact of commercial nanotubes with atmospheric oxygen.…”
