Building Ohmic Contact Interfaces toward Ultrastable Zn Metal Anodes

Advanced Science, 2021
Zn metal holds grand promise as the anodes of aqueous batteries for grid‐scale energy storage. However, the rampant zinc dendrite growth and severe surface side reactions significantly impede the commercial implementation.

Epitaxial Graphene and Graphene–Based Devices Studied by Electrical Scanning Probe Microscopy

Crystals, 2013
We present local electrical characterization of epitaxial graphene grown on both Si- and C-faces of 4H-SiC using Electrostatic Force Microscopy and Kelvin Probe Force Microscopy in ambient conditions and at elevated temperatures. These techniques provide

The effect of synthesis time on morphology and electronic structure of polyaniline [PDF]

Омский научный вестник, 2018
The paper investigates the morphology and electronic structure change of polyaniline as a function of the synthesis time. It is shown that the band gap of a polymer decreases with increasing duration of the synthesis time due to a change in the number

Work Function of Single-wall Silicon Carbide Nanotube

, 2011
Using first-principles calculations, we study the work function of single wall silicon carbide nanotube (SiCNT). The work function is found to be highly dependent on the tube chirality and diameter. It increases with decreasing the tube diameter.

Studying the Effect of Transport Layers on ZrS2/MEH-PPV Solar Cells: Using SCAPS -1D Software

East European Journal of Physics
This study investigates the effect of charge transport layers on the efficiency of Poly[2-methoxy-5-(2-ethylhexyloxy)-1,4-phenylenevinylene] (MEH_PPV) and Zirconium Disulfide (ZrS₂) solar cells using Scaps-1D software. It was found that by increasing the

Defects in oxide surfaces studied by atomic force and scanning tunneling microscopy

Beilstein Journal of Nanotechnology, 2011
Surfaces of thin oxide films were investigated by means of a dual mode NC-AFM/STM. Apart from imaging the surface termination by NC-AFM with atomic resolution, point defects in magnesium oxide on Ag(001) and line defects in aluminum oxide on NiAl(110 ...

Pazopanib Combined With Vincristine and Irinotecan in Relapsed Wilms Tumor: Encouraging Outcomes in a Heavily Pretreated Pediatric Cohort

Pediatric Blood &Cancer, EarlyView.
ABSTRACT Background While Wilms tumor (WT) typically has a favorable prognosis, relapsed cases—especially those with high‐risk histology—remain therapeutically challenging after intensive frontline therapy. The combination of vincristine and irinotecan has demonstrated activity in pediatric solid tumors, and pazopanib, a multi‐targeted tyrosine kinase ...
