Strengthening mechanism of electrocatalytic properties of high activity Fe-based amorphous alloys by low escape work nanocrystals

open access: yesJournal of Materials Research and Technology
Amorphous alloy is a popular choice for wastewater treatment because of its high active sites and high catalytic performance. It is different from the previous situation that the degradation performance of amorphous materials decreases first and then ...

Advances in Thermionic Energy Conversion through Single-Crystal n-Type Diamond

open access: yesFrontiers in Mechanical Engineering, 2017
Thermionic energy conversion, a process that allows direct transformation of thermal to electrical energy, presents a means of efficient electrical power generation as the hot and cold side of the corresponding heat engine are separated by a vacuum gap ...

Understanding and design of efficient carrier-selective contacts for solar cells

open access: yesAIP Advances, 2021
Numerous efforts have been devoted to either understanding or fabricating efficient carrier-selective contacts, since they play a significantly crucial role in high-performance solar cells. In this work, we demonstrate that the asymmetry between electron

Influence of electron scatterings on thermoelectric effect

open access: yes, 2012
In this work, we employed non-equilibrium Green's function to investigate the electron transport properties in the nanowire with the presence of scatterings. The scattering mechanism is modelled by using the concept of B\"uttiker probe.

Inelastic electron and light scattering from the elementary electronic excitations in quantum wells: Zero magnetic field

open access: yes, 2012
The most fundamental approach to an understanding of electronic, optical, and transport phenomena which the condensed matter physics (of conventional as well as nonconventional systems) offers is generally founded on two experiments: the inelastic ...

Nonextensive Interpretation Of Radiative Recombination In Electron Cooling

open access: yes, 2005
An interest for the low-energy range of the nonextensive distribution function arises from the study of radiative recombination in electron cooling devices in particle accelerators, whose experimentally measured reaction rates are much above the ...

Evaluation method of interface bonding strength of cemented carbide with additives

open access: yesScientific Reports
Cemented carbides are widely used in cutting tools, wear-resistant parts and other fields. In order to further improve the mechanical properties, additives are usually added to cemented carbides. The interface bonding strength of additives with WC and Co

Quantum optical signatures in strong-field laser physics: Infrared photon counting in high-order-harmonic generation

open access: yes, 2016
We analytically describe the strong-field light-electron interaction using a quantized coherent laser state with arbitrary photon number. We obtain a light-electron wave function which is a closed-form solution of the time-dependent Schrodinger equation (
