Removal of Congo Red Dye Molecules by MnO<SUB>2</SUB> Nanorods

Journal of Nanoscience and Nanotechnology (2014)

Bosi Yin Siwen Zhang Yang Jiao Yang Liu Fengyu Qu

Uniform MnO2 nanorods were synthesized successfully via a facile and effective hydrothermal approach. Scanning electron microscope images showed that the average diameter of the as-synthesized nanorod is about 30 nm and the length of that is about 5 μm, respectively. Photocatalytic experimental results indicate that Congo red can be degraded nearly completely (over 97%) after visible light irradiation of 120 min, demonstrating potential applications of such nanorod structures for wastewater purification.

Schottky barrier formation and dopant induced band bending in Au/TiO$_2$ interfaces from first principles

arXiv (Cornell University) (2015)

Yang Jiao Anders Hellman Yurui Fang Shiwu Gao Mikael Käll

An atomistic insight of Schottky barrier formation and subinterface band bending is achieved by ab initio simulations and analysis with previous models. Niobium doped rutile titania in contact with gold (Au/Nb:TiO$_2$) is used to model a Schottky diode. The local Schottky barrier height is shown to vary between 1.26 eV for the pristine interfaces to 0 eV for the case of dopant in interfacial layer due to the induced interface dipole field from contact and doping. Band bending is shown to originate from the dopant induced dipole fields between the interface and dopant site, whereas undoped Au/TiO$_2$ interface shows a step like barrier.

Optical and Electrical Properties of Ga-Doped ZnO Nanowire Arrays on Conducting Substrates

The Journal of Physical Chemistry C (2009)

Minjie Zhou Haojun Zhu Yang Jiao Yangyan Rao Suikong Hark

Large area Ga-doped ZnO nanowire arrays have been vertically grown on transparent conducting substrate by a simple chemical vapor deposition method. Experimental results reveal the well-aligned array morphology and the uniform Ga concentration in these nanowires with individual nanowires of single crystallinity. In particular, direct I−V measurements performed on a single nanowire on indium−tin oxide (ITO) substrate disclose both the low resistivity of nanowire and its Ohmic contact with the conducting substrate, which characteristics make them promising candidates for various optoelectronic and energy applications including photovoltaic cells.

Enhancement of thermal and mechanical properties of silicone rubber with γ-ray irradiation-induced polysilane-modified graphene oxide/carbon nanotube hybrid fillers

RSC Advances (2021)

Ke Cao Bolong Li Yang Jiao Yongjun Lü Liancai Wang

In this study, a polysilane-modified graphene oxide (GO) and carbon nanotube (CNT) nanocomposite (GO/CNTs-Si) was prepared as a thermal conductive nanofiller to enhance the thermal and mechanical properties of silicone rubber composites. By γ-ray-radiation 3-methacryloxypropyltrimethoxy silane (MPTMS) was polymerized on the surface of GO and CNTs to improve the interfacial interaction between the GO/CNTs-Si and SR matrix. FTIR characterization results demonstrated that polysilane modified the GO/CNTs successfully. The pristine GO/CNTs and resultant GO/CNTs-Si were individually incorporated into α,ω-dihydroxypolydimethylsiloxane to vulcanize SR composites. Compared with SR-GO/CNTs, SR-GO/CNT-Si exhibited better mechanical and thermal performance. Moreover, the time-dependent complex modulus of SR-GO/CNTs-Si was much higher than that of SR-GO/CNTs, which indicates longer service time and more stable performance. In terms of electronic packaging, SR-GO/CNTs exhibited better performance than the 1180B counterpart. The low value of warpage of chip packaged by SR-GO/CNTs implied that SR-GO/CNTs-Si could have potential application as the thermal interface electronic packaging material.

Pressure-induced spin reorientation and spin state transition inSrCoO3

Physical Review B (2015)

J. Y. Yang C. Terakura M. Medarde J. S. White Denis Sheptyakov

A series of high-pressure measurements including resistivity, ac and dc magnetic susceptibility, neutron powder diffraction, and synchrotron x-ray diffraction were performed to investigate the crystal structure and electronic states of the itinerant ferromagnet $\mathrm{SrCo}{\mathrm{O}}_{3}$. Two pressure-induced phase transitions were observed at about 1.1 and 45 GPa, corresponding to a spin reorientation and a spin-state transition, respectively, while the cubic crystal structure was stable with pressure up to 60.0 GPa. The origins of these electronic state changes are discussed and rationalized in the light of first-principles calculations.

Facile and low-cost synthesis of gold nanoparticles supported on cadmium sulphide flower-like three-dimensional assemblies

Micro & Nano Letters (2012)

Yang Jiao Xiaoming Ma Feifei Wang Kui Wang Peipei Zhang

Gold nanoparticles supported on cadmium sulphide (CdS) with flower-like three-dimensional assemblies were prepared successfully by a simple and facile method at room temperature. The preparation process takes place in ethylene glycol solution. Chloroauric acid is used as a source of golden nanoparticles (AuNPs). CdS and glutamate are used as the support and the stabiliser, respectively. X-ray diffraction patterns indicate that AuNPs possess a cubic crystal structure. High resolution transmission electron microscope measurements indicate that CdS support facilitate preparation of the highly dispersed AuNPs. Most importantly, the glutamate plays an important role in the monodisperse and smaller size (only about 2.9 nm) of AuNPs. These results indicate that the product has potential applications in degrading the organic dyes in the wastewater, catalysing organic reactions and applying to low-temperature CO oxidation.

Radiation synthesis of polysilane‐modified graphene oxide for improving thermal conductivity and mechanical properties of silicone rubber

Journal of Applied Polymer Science (2019)

Pei Dai Yang Jiao Huiling Ma Xinmiao Zeng Yongjun Lü

ABSTRACT Functionalized graphene oxide (named GO‐Si) was synthesized with graphene oxide and triethoxyvinylsilane (TEVS) using tetrahydrofuran solution by γ‐ray irradiation. TEVS was successfully covered onto GO sheets, and the polysilane content on GO‐Si was increased upon increasing the absorbed dose. The structures of GO‐Si were verified by atomic force microscopy, Fourier transform infrared spectroscopy, and X‐ray photoelectron spectroscopy. The resultant GO‐Si was dispersed into α,ω‐dihydroxypolydimethylsiloxane to prepare room temperature vulcanized silicone rubber composites (named SR/GO‐Si) by solution casting. The dispersion of GO‐Si was more uniform than that of GO. Compared to that of pure SR, the thermal conductivity of SR/GO‐Si‐1.95 composites was increased 1.5‐fold, and its tensile strength and elongation at break increased 78.6 and 71.4%, respectively. It was expected that SR/GO‐Si would have potential application as the thermal interface material. © 2019 Wiley Periodicals, Inc. J. Appl. Polym. Sci. 2019 , 136 , 47776.

Atomistic mechanism of charge separation upon photoexcitation at the dye–semiconductor interface for photovoltaic applications

Physical Chemistry Chemical Physics (2011)

Yang Jiao Zijing Ding Sheng Meng

Charge separation in excited states upon visible light absorption is a central process in photovoltaic solar cell applications. Employing state-of-the-art first principles calculations based on time-dependent density functional theory (TDDFT), we simulate electron-hole dynamics in real time and illustrate the microscopic mechanism of charge separation at the interface between organic dye molecules and oxide semiconductor surfaces in dye-sensitized solar cells. We found that electron-hole separation proceeds non-adiabatically on an ultrafast timescale <100 fs at an anthocyanin/TiO(2) interface, and it is strongly mediated by the vibrations of interface Ti-O bonds, which anchor the dye onto the TiO(2) surface. The obtained absorption spectrum and electron injection timescale agree with experimental measurements.
