Recent advances in materials science and nanotechnology have lead to considerable interest constructing ion‐channel‐mimetic nanofluidic systems for energy conversion storage. The conventional viewpoint suggests that gain high electrical energy, the longitudinal dimension of nanochannels ( L ) should be reduced so as bring down resistance ion transport provide ionic flux. Here, counterintuitive channel‐length dependence is described osmotic power generation. For short (with length < 400...
Abstract Nanopores in ultrathin or atomically thin membranes attract broad interest because the infinitesimal pore depth allows selective transport of ions and molecules with ultimate permeability. Toward large‐scale osmotic energy conversion, great challenges remain extrapolating promising single‐pore demonstration to really powerful macroscopic applications. Herein, origin ion nanopores is systematically investigated. Based on a precise Poisson Nernst–Planck model calculation, it found...
In this work, we report on a flexible thermoelectric nanogenerator (NG) based the MoS2/graphene nanocomposite. The nanocomposite shows enhanced performance, compared with that solely MoS2 nanomaterials, which may be due to electrical conductivity resulting from graphene acting as charge transfer channel in composites. NG can further applied self-powered sensor for temperature measurement. This work indicates is promising material harvesting environmental thermal energy.
To get precise simulation for ion transport in porous nanofluidic systems, the influence of neighbouring nanopores should be seriously considered.
Abstract Directly mapping local phonon dispersion in individual nanostructures can advance our understanding of their thermal, optical, and mechanical properties. However, this requires high detection sensitivity combined spatial, energy momentum resolutions, thus has been elusive. Here, we demonstrate a four-dimensional electron loss spectroscopy technique, present position-dependent measurements boron nitride nanotubes. By scanning the beam real space while monitoring both transfer, are...
Summary of main observation and conclusion Osmotic power generated by mixing ionic solutions different concentration is an underutilized clean energy resource that satisfy potentially the ever‐growing demand. For decades, substantial efforts are made to enhance density. Toward this goal, we once developed a heterogeneous nanoporous membrane comprising heterojunctions between negatively charged mesoporous carbon positively macroporous alumina harvest electric from salinity difference achieved...
A concise single-pore model with a finite reservoir is sufficiently accurate to simulate osmotic energy conversion in nanoporous materials.
The microstructural evolution of Dy2O3-TiO2 powder mixtures during ball milling and post-milled annealing was investigated using XRD, SEM, TEM, DSC. At high ball-milling rotation speeds, the were fined, homogenized, nanocrystallized, later completely amorphized, transformation Dy2O3 from cubic to monoclinic crystal structure observed. amorphous resulted Dy2O3, not Dy2O3. However, at low only fined homogenized. An intermediate phase with a similar that Dy2TiO5 detected in annealed 800 1000...
Strontium titanate (SrTiO is a promising n-type material for thermoelectric applications. However, its relatively high thermal conductivity limits performance in efficiently converting heat into electrical power through effect. This work shows that the of SrTiO can be effectively reduced by annealing treatments, an integrated study laser flash measurement, scanning electron microscopy, Fourier transform infrared spectroscopy, x-ray absorption fine structure, and first-principles...
