Dually fixed SnO2 nanoparticles (DF-SnO2 NPs) on graphene nanosheets by a polyaniline (Pani) coating was successfully fabricated via two facile wet chemistry processes, including anchoring SnO2 NPs onto graphene nanosheets via reducing graphene oxide by Sn(2+) ion, followed by in situ surface sealing with the Pani coating. Such a configuration is very… (More)
Strain sensors with excellent flexibility, stretchability, and sensitivity have attracted increasing interests. In this paper, a highly stretchable and ultrasensitive strain sensor based on reduced graphene oxide microtubes-elastomer is fabricated by a template induced assembly and followed a polymer coating process. The sensors can be stretched in excess… (More)
This paper address the problem of designing jointly the linear transmitters and receiver in a non-regenerative MIMO relay system, where linear processing is applied at the source, relay and destination node, using minimum mean square error (MMSE) criterion. Under the average power constraints at both the source and relay node, the iterative optimization… (More)
A series of Mn-based mixed metal oxide catalysts (Co-Mn-O, Fe-Mn-O, Ni-Mn-O) with high surface areas were prepared via low temperature crystal splitting and exhibited extremely high catalytic activity for the low-temperature selective catalytic reduction of nitrogen oxides with ammonia.
Aligned micro-sized carbon tubes have been successfully synthesized on silicon substrate by pyrolysis of cyclohexane/ferrocene in the presence of water, a spectacular feature of which is that the multi-wall carbon nanotubes formed in situ act as the basic building blocks for the construction of micro-tubes via a "multi-scale" self-assembly process.
Power offset is zero-order term in the SNR-capacity curve. In this contribution, approximate analysis of power offset is used to describe single-user two transmit multiple receive MIMO system with uniform linear antenna arrays of fixed length by fitting determinant curve of tri-diagonal toeplitz matrix. The simulation results show that approximation of… (More)
Power offset is zero-order term in the capacity versus signal-to-noise ratio curve. In this paper, approximate analysis of power offset is presented to describe MIMO system with uniform linear antenna arrays of fixed length. It is assumed that the number of receive antenna is larger than that of transmit antenna. Spatially Correlated MIMO Channel is… (More)
In this paper, a novel precoding technique is proposed to improve the performance of the MIMO interference channel (MIC). Since the reachable sum-rate is a long-term problem, we present an iterative approach to improve the power-offset and achieve a higher sum-rate than the ordinary scheme. Considering the difference between MIC and multi-input multi-output… (More)
Sodium ion batteries (SIBs) have been considered as a promising alternative to lithium ion batteries, owing to the abundant reserve and low-cost accessibility of the sodium source. To date, the pursuit of high-performance anode materials remains a great challenge for the SIBs. In this work, carbon-stabilized interlayer-expanded few-layer MoSe2 nanosheets… (More)
