Simple Method for the Preparation of Fe3O4/MWCNT Nanohybrid as Radar Absorbing Material (RAM) [PDF]

Iranian Journal of Chemistry & Chemical Engineering, 2018
We have successfully prepared Fe3O4/MWCNT nanohybrid with a very simple and economical method. Multi-Walled Carbon NanoTubes (MWCNT) encapsulated with Fe3O4 nanoparticles were synthesized via pyrolyzing of ferrocene. The sample was characterized with XRD,

Understanding Sulfur Redox Mechanisms in Different Electrolytes for Room-Temperature Na–S Batteries

Nano-Micro Letters, 2021
This work reports influence of two different electrolytes, carbonate ester and ether electrolytes, on the sulfur redox reactions in room-temperature Na–S batteries. Two sulfur cathodes with different S loading ratio and status are investigated.

Electronic transport through electron-doped Metal-Phthalocyanine Materials

, 2006
We report an insulator-metal-insulator transition in films of five metal phthalocyanines (MPc) doped with alkali atoms. Electrical conduction measurements demonstrate that increasing the alkali concentration results in the formation of a metallic state ...

First-principles calculations of hot-electron lifetimes in metals [PDF]

Phys. Rev. B 61, 13484 (2000), 2000
First-principles calculations of the inelastic lifetime of low-energy electrons in Al, Mg, Be, and Cu are reported. Quasiparticle damping rates are evaluated from the knowledge of the electron self-energy, which we compute within the GW approximation of many-body theory.

Solid state thin electrolyte to overcome transparency-capacity dilemma of transparent supercapacitor

Scientific Reports, 2022
For portable and transparent electronic applications, transparent supercapacitor (T-SC) is developed to act as an energy storing device. Because electric and optical characteristics of the supercapacitor are strongly dependent on its thickness, all solid

D'yakonov-Perel' spin relaxation for degenerate electrons in the electron-hole liquid [PDF]

Phys. Rev. B 83, 155205 (2011), 2010
We present an analytical study of the D'yakonov-Perel' spin relaxation time for degenerate electrons in a photo-excited electron-hole liquid in intrinsic semiconductors exhibiting a spin-split band structure. The D'yakonov-Perel' spin relaxation of electrons in these materials is controlled by electron-hole scattering, with small corrections from ...

AAPM Medical Physics Practice Guideline MPPG 17.a: Quality management for mammography review workstation displays

Journal of Applied Clinical Medical Physics, EarlyView.
Abstract The Mammography Quality Standards Act (MQSA) sets quality standards for displays used to interpret mammography images. With the shift to digital mammography and the widespread use of remote reading workstations (RWS), updated quality management (QM) programs are needed to ensure consistent image presentation and accurate interpretation.
