Key Scientific Contributions

[A] Radio Frequency and Microwave Electronics: Theory and Design for Active Frequency Selective Surfaces(AFSS)

Most attention is paid to frequency selective surfaces (FSS).For improving the performance of FSS, intelligence algorithm is used to optimize its parametric model, such as Genetic Algorithm (GA). GA is used to optimize the EM performances of FSS due to its superiority to solve multi-variables optimization problem. By using GA and optimizing the geometry and size of the FSS unit cell as well as the thickness and dielectric constant of the substrate material, it is possible to design multiband artificial magnetic conducting surfaces that work for nearly any desired combination of operating frequencies. However, the traditional GA can not apply to the cases of evaluating polymorphic individual which having opposite performances, such as switchable absorber/reflector. In this case, it has to comprehensively evaluate the performance in ON and OFF state of each individual during the optimization.

We investigate a wideband switchable FSS absorber/reflector. Discussions are carried out around how to integrate broadband absorption and switchable performance into FSS structure. Polymorphic union evaluation genetic algorithm (PUE-GA) is put forward to optimize the parametric model of FSS element and comprehensive evaluate the performances of switchable FSS. The results showed that the switchable absorber/reflector could both have wideband absorption and switchable properties over the C-band frequency range (4–8 GHz), and PUE-GA is able to improve the design of switchable FSS absorber/reflector.

[B] Energy Electronics & Supercapacitors: Scientific Fundamentals of Energy Storage Electrochemistry and Technological Application of Supercapacitors

With the fast-growing energy depletion and environmental degradation, numerous efforts have been made to develop energy storage and conversion from alternative energy sources, such as, lithium ion battery, supercapacitors, fuel cell. Supercapacitors as new energy storage devices, have drawn an increasing attention because they can provide an energy density higher than traditional capacitors, and greater power density and longer cycling ability compared to rechargeable batteries. Binary metal compounds (oxides,hydroxides and sulfides) possessing multiple oxidation states and/or architectures that enable multiple redox reaction activity, have been reported to exhibit a higher performance than single metal components. Most of them seem to be some of the most promising and low cost materials for supercapacitors. For instance, the ultrathin mesoporous NiCo₂O₄ nanosheets on conductive nickel foam exhibit superior pseudocapacitive of 1450 F g, even at a very high current density of 20 A g, and excellent cycling performance at high rates. The Cobalt-nickel layered double hydroxides have a high specific capacitance of 2104 F g. The porous NiCo₂S₄ nanotubes show a specific capacitance of 1093 F g at a current density of 0.2 A g. Up to now, the unitary nickel or manganese compounds have been widely studied for supercapacitors, due to their excellent electrochemical performance, low cost (especially for the material systems with containing a large amount of cobalt) and environmental friendly. However, the synthesis and electrochemical characterization of the binary Ni-Mn compounds (Ni-Mn oxides or Ni-Mn sulfides) are rarely reported, which may exhibit more excellent electrochemical performances than that of the unitary nickel or manganese compounds. Therefore, preparation of binary Ni-Mn oxides or sulfides, and study of their formation mechanism are very usefulfor application-specific supercapacitors.

The development of three-dimensional (3D) micro-nanostructures with one-dimensional (1D) nanostructures as building units can provide a promising solution to enhance the capacitive performance because of their high surface area, short electron and ion transport pathways. Among them, the 3D hollow structures such as, hollow ZnO, Fe₂O₃, CuO, ZnS, with 1D nanoneedle nanostructure in the surface of shell were carried out, especially for application in supercapacitors. However, most of the previous syntheses usually involve the use of hard templates, soft surfactants, toxic organic solvents, and complicated procedures. The resultant structures are largely limited to low-order structures and are not very efficient for practical applications. Therefore, it is essential but challenging to develop a facile, controllableand environmental friendly method to produce binary Ni-Mn compounds of hollow hedgehog-like structures with uniform size ordered 1D nanostructures as high-performance electrode materials for supercapacitor applications. In our work, we report a one-step and novel approach synthesis of hollow hedgehog-like binary Ni-Mn precursor based on directional growth of Mn induced. In the formation process of hollow hedgehog-likestructure, Mn play a very important inducing role which is similar to the growth of the pute hollow manganese dioxide.The plausible formation mechanism of such directional Mn-induced synthesis can be described as shown in Figure 1. The induced mechanism is conducted as follows: (1) In the beginning, the OH formed by urea hydrolysis reacts with Ni and aggregates to form nucleation centre;(2) The nucleation centre subsequently adsorp Mn and form flocculent nanostructures at the surface of nucleation product; (3) After prolonged hydrothermal treatment, the internal of nucleation gradually form hollow structure as the induction process; (4) Finally, the precursor will further be inducted and crystallize into shell and needle-like nanostructures in surface of shell, forming a complete hollow hedgehog-like framework. The hollow hedgehog-like binaryNi-Mn oxides and sulfides are obtained after thermal treatment and vulcanization for hollow hedgehog-like binaryNi-Mn precursor and retain the morphology of the precursor with one-dimensional (1D) nanoneedles as building units. The excellent electrochemicalperformance of hollow hedgehog-like Ni-Mn oxides and sulfides benefit from its unique 3D open structure, effectively buffering the volume strains during the ion electrolyte adsorption/desorption process。

[C] Nanoelctronics: Computational Nanoscale Materials Science and Electronic Structure Analysis by First Principle Calculations

Graphene, which is an exciting two-dimensional material, shows great promise for the fabrication of nanoscale devices with its interesting semimetal electronic properties. And quasi-one-dimensional graphene nanoribbons (GNRs) can generally be either metallic or semiconducting depending on the patterns formed by their edges. What’s more, GNRs sub 10 nm present the excellent semiconducting character because of the quantum confinement effect and edge effect. Thus the ultra-narrow GNRs can be the ideal materials for lots of nanoscale devices. Nowadays, the usual methods to fabricate GNRs are electron-beam lithography and plasma etching, chemical synthesis, and chemical vapor deposition method. Most GNRs fabricated by these ways are difficult to ensure the crystallographic orientation and achieve smooth graphene edges simultaneously during fabrication. And it’s hard to reach the target of sub 10 nm.

The productions have smooth edge and a narrow width distribution (10–20 nm). In this way, the width of GNRs can be well controlled. From then on, the method to fabricate GNRs through unzipping CNT becomes a hot issue. The mechanism of oxygen-driven unzipping of CNT was investigated using density functional theory calculations. Unzipping starts with attacking one of the internal C–C bonds of CNT, then stretching and breaks it. Soon afterwards, many researches were carried on. Also there are other adsorbates to break C-C bond, such as H atom, transition metal, and alloy. Furthermore, kinds of production could be got through this way according to different requirements, such as bilayer GNRs with tunable width, aligned GNR arrays, and magnetoresistive device. Very recently, this method has already been applied into unzipping and cutting of graphene. However, there are also some problems need to explore. The irregular initial adsorption of O adatom and the relatively high energy barrier of O diffusion on CNTs, will go against to ensure smooth edges of GNRs.

On the other hand, the charge transfer and electron redistribution caused by external electric field will apparently affect the physical and chemical properties of nano materials. The effect of electric field on the electronic structure of nano materials, such as single-walled carbon nanotube (SWCNT), boron nitride nanotube, graphene, bilayer graphene, GNRs, has been investigated, and a tunable band gap could be achieved for these materials. In addition, the electron redistribution will change the intensity of atomic interaction and chemical bond. The gases, such as H₂, O₂, N₂O, adsorption on nano materials could be influenced by electric field greatly. Even a reversible reduction and oxidation of graphene oxide was realized by electric field. Furthermore, too large electric field even could break the structure of hydrogenated SWCNT.

In our work, we investigate the effect of electric field on orientation-selective oxygen-driven unzipping of CNT. The relaxed structure of CNT, the binding energies and the diffusion barrier of O adatom at kinds of site on CNT under different electric fields are calculated to study the possibility of longitudinal unzipping SWCNT.

Carbon dioxide, nitrogen dioxide and sulfur dioxide are acidic gaseous pollutants, coming from both natural and industrial procedures, accumulating in the atmosphere, reacting under certain atmospheric conditions, and leading to greenhouse effect, photochemical smog and acid rain, which are great threats to global processes and human health nowadays.

The most efficient way to reducehazards of acidic gases has been proven to be gases capture after the burning of fuels and before the emission of acidic gases. Ammonia scrubbing, denitrification processes and flue gas desulfurization are the traditional methods to control the emission of CO₂, NO₂ and SO₂.However, these processes will be more or less high absorbent and running cost, low removal efficiency, poor absorbent utilization ratio, high secondary pollution, and large occupying area. In this paper, a novel nanomaterial with large specific area, high stability and less contamination, will be studied on the removal of acidic gases.

Graphene, which is an exciting two-dimensional material with many interesting semimetal electronic properties, shows great promise for fabrication of nanoscale devices. And modified graphenes are put forward to avoid its physical native defect while applying in devices, such as graphene oxide (GO), graphene nanoribbons, crumpled graphene, doped graphene, metal decorated graphene and so on. Among them, GO exhibits a moderate conductivity, high chemical stability, and excellent mechanical, optical, thermal, electrochemical properties. Hence, GO is prepared and applied into gas sensor or storage, high-performance fibers, composite membranes, electro-chemical applications, energy devices, field effect transistors and so forth. Here, its outstanding performance in gas storage catches our eyes.

In our work, much more eco-friendly, cheaper and lighter metals (Li, Al) are selected to decorate GO to investigate acidic gases (CO₂, NO₂and SO₂) adsorption effectiveness comparing with transition metal (Ti). High binding energy and oxygen adsorption restraint are the targets. The relaxed structures of pure and metal decorated GO, the binding energies of gases on metal decorated GO and charge transfer are calculated to study the efficient removal of acidic gases.

The adsorption of several acidic gases (CO₂, NO₂ and SO₂) on light metal (Li, Al) decorated graphene oxide (GO) is theoretically studied, based on the first-principle calculations. Configuration relaxation, binding energy and charge transfer are carried out to discuss the acidic gas adsorption ability of light metal decorated GO. It’s found out that Li, Al could be anchored stably by hydroxyl and epoxy groupson GO, and then a strong adsorption will occur of CO₂, NO₂ and SO₂above these light metals. In contrast to Ti, Li decorated GO performs a comparable adsorption ability of acidic gases, but a much smaller interaction with O₂ about 2.85 ~ 3.98 eV lower in binding energy; and Al decorated GO displays much higher binding energy of all acidic gases with enhancement of about 0.59 ~ 2.29 eV.The results of enhanced acidic gas adsorption ability and a reduced interferenceof O₂, imply that Li, Al decorated GO may be useful and promising for collection and filtration of exhaust gases.
