How does the B,F-monodoping and B/F-codoping affect the photocatalytic water-splitting performance of g-C3N4?

22-Jul-2016 | Kaining Ding; Lili Wen; Mengyue Huang; Yongfan Zhang; Yunpeng Lu; Zhongfang Chen, Physical Chemistry Chemical Physics, 2016

By means of density functional theory (DFT) computations, we investigated the electronic and optical properties of B,F-monodoped and B/F-codoped graphitic carbon nitride (g-C3N4) to explore the doping effects on the photocatalytic performance of g-C3N4. It is found that F atom addition plays a ...


Effects of induced optical tunable and ferromagnetic behaviors of Ba doped nanocrystalline LaB6

22-Jul-2016 | Lihong Bao; Xiaoping Qi; Tana; Lumen Chao; O. Tegus, Physical Chemistry Chemical Physics, 2016

Multiple nanocrystalline rare-earth hexaborides La1−xBaxB6 have been synthesized via a single step solid-state reaction. The Ba doping effects on crystal structure, grain morphology, magnetic and optical absorption properties were investigated using XRD, FESEM, HRTEM, SQUID magnetometry and ...


Magnetism, Structures and Stabilities of Cluster Assembled TM@Si Nanotubes (TM=Cr, Mn and Fe): A density functional study

22-Jul-2016 | Debashis Bandyopadhyay; Kapil Dhaka, Dalton Transactions, 2016

Present study reports the transition metal (TM=Cr, Mn and Fe) doped silicon nanotubes with tunable band structure and magnetic properties by the careful selection of cluster assembly as building blocks using first-principle density functional theory. We found that the transition metal doping and ...


Effect of Halogen Doping on Nanocarbon Catalyst Synthesized by Solution Plasma Process for Oxygen Reduction Reaction

22-Jul-2016 | Takahiro Ishizaki; Yuta Wada; Satoshi Chiba; Sou Kumagai; Hoonseung Lee; Ai Serizawa; Oi Lun Helena Li; Gasidit Pano ..., Physical Chemistry Chemical Physics, 2016

Heteroatom-containing carbon catalysts have attracted much attention for the oxygen reduction reaction (ORR) in metal-air batteries and fuel cells. The solution plasma process allows the easy synthesis of heteroatom-containing carbon nanoparticles (CNP) from mixtures of carbon and heteroatom ...


A high-performance dual-function material: self-assembled super long [small alpha]-Fe2O3 hollow tubes with multiple heteroatoms (C-, N- and S-) doping

19-Jul-2016 | Jianfeng Li; Wen Zhang; Guangtao Zan; Qingsheng Wu, Dalton Transactions, 2016

Novel heteroatoms self-doped super long α-Fe2O3 hollow tubes have been synthesized through the combination of hydrothermal and calcination technique using the chicken eggshell membrane as template and dopant. The obtained α-Fe2O3 super long hollow tubes are composed of close arranged building ...


Pinning effect of reactive elements on adhesion energy and adhesive strength of incoherent Al2O3/NiAl interface

19-Jul-2016 | Zhao Zhang; Ruifeng Zhang; Dominik Legut; Dongqing Li; Shihao Zhang; Zhongheng Fu; Hongbo Guo, Physical Chemistry Chemical Physics, 2016

The profound effects of reactive elements (REs) on adhesion energy and adhesive strength of α-Al2O3/β-NiAl interface in thermal barrier coating (TBC) system have attracted increasingly attention because REs-doping have played significant role in improving the thermal cycling lifetime of TBC. ...


Element-selective resonant state in M-doped SnTe (M = Ga, In, and Tl)

19-Jul-2016 | X. J. Tan; G. Q. Liu; J. T. Xu; H. Z. Shao; J. Jiang; H. C. Jiang, Physical Chemistry Chemical Physics, 2016

The band engineering of M-doped SnTe (M = Ga, In, and Tl) is investigated by using first-principles calculations. Being consistent with experimental measurements, our calculations found that Ga doping hardly changes the valence band, while In doping introduces an obvious resonant state near the ...


Impact of Ho3+-doping on 13C dynamic nuclear polarization using trityl OX063 free radical

19-Jul-2016 | Andhika Kiswandhi; Peter Niedbalski; Christopher Parish; Pavanjeet Kaur; André Martins; Leila Fidelino; Chalermchai ..., Physical Chemistry Chemical Physics, 2016

We have investigated the effects of Ho-DOTA doping on the dynamic nuclear polarization (DNP) of [1-13C] sodium acetate using trityl OX063 free radical at 3.35 T and 1.2 K. Our results indicate that addition of 2 mM Ho-DOTA on 3 M [1-13C] sodium acetate sample in 1 [ ] : [ ] 1 v/v glycerol [ ] : [ ...


Ion‐beam induced effects in multi‐layered semiconductor systems

15-Jul-2016 | Elke Wendler, Nikolai A. Sobolev, Andrés Redondo‐Cubero, Katharina Lorenz, physica status solidi (b), 2016

In this article, ion‐beam induced effects in multi‐layered III–V semiconductor structures are reviewed. Besides doping, important effects occurring during ion irradiation are defect formation and diffusion, amorphisation and intermixing. It is shown that these processes are closely related to ...


Materials, Vol. 9, Pages 579: Nb5+-Doped SrCoO3−δ Perovskites as Potential Cathodes for Solid-Oxide Fuel Cells

15-Jul-2016 | Cascos, Vanessa ; Alonso, José Antonio; Fernández-Díaz, María Teresa, Materials, 2016

SrCoO3−δ outperforms as cathode material in solid-oxide fuel cells (SOFC) when the three-dimensional (3C-type) perovskite structure is stabilized by the inclusion of highly-charged transition-metal ions at the octahedral positions. In a previous work we studied the Nb incorporation at the Co ...
