Nitrogen-doped SWCNTs with enhanced carbocatalysis were investigated in the activation of superoxides by advanced oxidation and theoretical calculations.
2D inorganic materials are now breeding a wide‐ranging series of energy applications including catalysis, electrochemical activity, thermoelectricity and spin electronic devices. However, the physicochemical property virgin can scarcely satisfy modern increasing diversificated demand theory applcations. In this regard, confined electron phonon structures will be directive for rationally tuning intrinsic properties materials. Given this, vacancies in even infinitesimal concentrations could...
Vacancy is a very important class of phonon scattering center to reduce thermal conductivity for the development high efficient thermoelectric materials. However, conventional monovacancy may also act as an electron or hole acceptor, thereby modifying electrical transport properties and even worsening performance. This issue urges us create new types vacancies that scatter phonons effectively while not deteriorating transport. Herein, taking BiCuSeO example, we first reported successful...
Defect engineering, at the core of field thermoelectric studies, serves as a scaffold for engineering intrinsic electrons' and phonons' behaviors to tailor parameters through direct impacts band phonon which can modify electronic structure transport behavior enhance power factor (PF = σS2) reduce lattice thermal conductivity (κl). By virtue implementation defect past decades have witnessed great progress in research synergistic optimization inter-correlated parameters, substantial...
The world's supply of fossil fuels is quickly being exhausted, and the impact their overuse contributing to both climate change global political unrest. In order help solve these escalating problems, scientists must find a way either replace combustion engines or reduce use. Thermoelectric materials have attracted widespread research interest because potential applications as clean renewable energy sources. They are reliable, lightweight, robust, environmentally friendly can reversibly...
The ever-increasing world-wide energy consumption and crisis of environmental pollution have aroused enthusiasm on developing high-efficiency green-clean conversion technology. Thermoelectric materials enable an environmentally friendly between heat electricity, therefore serve as optimum candidate for solving the current dilemma contribute to carbon-neutral target. Among thermoelectric family, layered shared a great portion with impressive performance originating from their...
Multifarious defects are introduced in SnTe by CuSbSe 2 alloying to induce full-scale phonon scattering, which leads an ultra-low lattice thermal conductivity, reaching the amorphous limit, and achieves prominent thermoelectric performance.
Many layered superlattice materials intrinsically possess large Seebeck coefficient and low lattice thermal conductivity, but poor electrical conductivity because of the interlayer transport barrier for charges, which has become a stumbling block achieving high thermoelectric performance. Herein, taking BiCuSeO as an example, it is demonstrated that efficient charge release can increase carrier concentration, thereby activating multiple Fermi pockets through Bi/Cu dual vacancies Pb codoping....

Since the rise of two-dimensional (2D) semiconductors, it seems that electronic devices will soon be upgraded with spintronics, in which manipulation spin degree freedom endows obvious advantages over conventional charge-based electronics. However, as most crucial prerequisite for above-mentioned expectation, 2D semiconductors adjustable magnetic interaction are still rare, has greatly hampered promotion spintronics. Recently, transition metal phosphates have attracted tremendous interest...

These contribute...
In thermoelectric research, the introduction of a dopant can suppress lattice thermal conductivity (κ1) through phonon scattering and optimize power factor (PF) by changing behavior carriers, which are key prerequisites for high performance. However, electrical (κe) also increase with (σ), may override optimization in PF be detrimental to improvement final ZT. this work, we highlight an amphoteric doping method using Mn atoms substitute both Ag Sb AgSbTe2. The MnSb positive p-type AgSbTe2...
Recently, ternary Cu-based Cu-IV-Se (IV = Sb, Ge, and Sn) compounds have received extensive attention in the thermoelectric field. Compared with Cu-Sb-Se Cu-Sn-Se, Cu-Ge-Se been less studied due to its poor Seebeck coefficient high thermal conductivity. Here, Cu2GeSe3 material electrical conductivity was first prepared, then, effective mass increased by doping S, which led of doped sample being 1.93 times higher than that pristine at room temperature. Moreover, alloying Ag Cu site...
In the high latitudes, icy patches on road are frequently generated and have a wide distribution, which difficult to remove obviously affect normal usage of highways, bridges airport runways.
