Beneficial effect of Re-doping on the electrochemical HER activity of MoS2 fullerenes

26-Aug-2015 | Manjeet Chhetri; Uttam Gupta; Lena Yadgarov; Rita Rosentsveig; Reshef Tenne; Chintamani Nagesa Ramachandra Rao, Dalton Transactions, 2015

Electrochemical generation of hydrogen by non-precious metal electrocatalysts at a lower overpotential is a thrust area ofresearch directed towards sustainable energy. The exorbitant costs associated with Pt based catalysts is the major bottleneck associated with the commercial scale hydrogen ...

A Van Der Waals Homojunction: Ideal p–n Diode Behavior in MoSe2

21-Aug-2015 | Youngjo Jin, Dong Hoon Keum, Sung‐Jin An, Joonggyu Kim, Hyun Seok Lee, Young Hee Lee, Advanced Materials, 2015

A MoSe2 p–n diode with a van der Waals homojunction is demonstrated by stacking undoped (n‐type) and Nb‐doped (p‐type) semiconducting MoSe2 synthesized by chemical vapor transport for Nb substitutional doping. The p–n diode reveals an ideality factor of ≈1.0 and a high external quantum ...

Precipitation Synthesis and Color‐Tailorable Luminescence of α‐Zr(HPO4)2: RE3+(RE = Eu, Tb) Nanosheet Phosphors

21-Aug-2015 | Shikao Shi, Xiaojun Zhang, Shuping Wang, Lina Geng, Jianjun Zhang, Wei Chen, Journal of the American Ceramic Society, 2015

The rare earth (RE=Eu and Tb) ions‐doped α‐Zr(HPO4)2 (ZrP) nanosheet phosphors were synthesized by direct precipitation method, and their structures and photoluminescence properties were investigated. The results of X‐ray diffraction and scanning electron microscopy indicated that the systems ...

Independent Tuning of Electronic Properties and Induced Ferromagnetism in Topological Insulators with Heterostructure Approach

21-Aug-2015 | Zilong Jiang; Cui-Zu Chang; Chi Tang; Peng Wei; Jagadeesh S. Moodera; Jing Shi, Nano Letters, 2015

The quantum anomalous Hall effect (QAHE) has been recently demonstrated in Cr- and V-doped three-dimensional topological insulators (TIs) at temperatures below 100 mK. In those materials, the spins of unfilled d-electrons in the transition metal dopants are exchange coupled to develop a ...

Well-Defined Thiolated Nanographene as Hole-Transporting Material for Efficient and Stable Perovskite Solar Cells

21-Aug-2015 | Jing Cao; Yu-Min Liu; Xiaojing Jing; Jun Yin; Jing Li; Bin Xu; Yuan-Zhi Tan; Nanfeng Zheng, Journal of the American Chemical Society, 2015

Perovskite solar cells (PSCs) have been demonstrated as one of the most promising candidates for solar energy harvesting. Here, for the first time, a functionalized nanographene (perthiolated trisulfur-annulated hexa-peri-hexabenzocoronene, TSHBC) is employed as the hole transporting material ...

Dual Europium Luminescence Centers in Colloidal Ga2O3 Nanocrystals: Controlled in Situ Reduction of Eu(III) and Stabilization of Eu(II)

21-Aug-2015 | Arunasish Layek; Baran Yildirim; Vahid Ghodsi; Lisa N. Hutfluss; Manu Hegde; Ting Wang; Pavle V. Radovanovic, Chemistry of Materials, 2015

Introducing multiple luminescent centers into colloidal nanocrystals is an attractive way to impart new optical properties into this class of materials. Doping disparate ions into specific nanocrystals is often challenging, due to the preferential incorporation of one type of dopant. Here, we ...

Multi‐frequency (S, X, Q and W‐band) EPR and ENDOR Study of Vanadium(IV) Incorporation in the Aluminium Metal–Organic Framework MIL‐53

20-Aug-2015 | Irena Nevjestić, Hannes Depauw, Karen Leus, Vidmantas Kalendra, Ignacio Caretti, Gunnar Jeschke, Sabine Van Doorslae ..., ChemPhysChem, 2015

Abstract Doping the well‐known metal–organic framework MIL‐53(Al) with vanadium(IV) ions leads to significant changes in the breathing behaviour and might have repercussions on the catalytic behaviour as well. To understand the properties of such a doped framework, it is necessary to determine ...
