Different Photostability of BiVO4 in Near-pH-Neutral Electrolytes
Siyuan Zhang, Ibbi Ahmet, Se-Ho Kim +11
Photoelectrochemical water splitting is a promising route to produce hydrogen from solar energy. However, corrosion of semiconducting photoelectrodes remains a fundamental challeng…
Atomic scale mapping of impurities in partially reduced hollow TiO2 nanowires
Joohyun Lim, Se-Ho Kim, Raquel Aymerich Armengol +5
The incorporation of impurities during the chemical synthesis of nanomaterials is usually uncontrolled and rarely reported because of the formidable challenge that constitutes meas…
Direct imaging of dopant and impurity distributions in 2D MoS
Se-Ho Kim, Joohyun Lim, Rajib Sahu +4
Molybdenum disulfide (MoS) nanosheet is a two-dimensional material with high electron mobility and with high potential for applications in catalysis and electronics. We synthes…
Nanocrystalline equiatomic CoCrFeNi alloy thin films: Are they single phase fcc?
Maya Kini, Subin Lee, Alan Savan +9
The bulk quaternary equiatomic CoCrFeNi alloy is studied extensively in literature. Under experimental conditions, it shows a single-phase fcc structure and its physical and mechan…
Properties and influence of microstructure and crystal defects in FeVAl modified by laser surface remelting
Leonie Gomell, Moritz Roscher, Hanna Bishara +3
Laser surface remelting can be used to manipulate the microstructure of cast material. Here, we present a detailed analysis of the microstructure of FeVAl following laser surfa…
Microstructure evolution and thermal stability of equiatomic CoCrFeNi films on (0001)alpha-Al2O3
Younes Addab, Maya K. Kini, Blandine Courtois +6
Homogeneous face-centered cubic (fcc) polycrystalline CoCrFeNi films were deposited at room temperature on (0001)alpha-Al2O3 (c-sapphire). Phase and morphological stability of 200…
Could face-centered cubic titanium in cold-rolled commercially-pure titanium only be a Ti-hydride?
Yanhong Chang, Siyuan Zhang, Christian H. Liebscher +7
A face-centered cubic (FCC) phase in electro-polished specimens for transmission electron microscopy of commercially pure titanium has sometimes been reported. Here, a combination…
Rational Strain Engineering in Delafossite Oxides for Highly Efficient Hydrogen Evolution Catalysis in Acidic Media
Filip Podjaski, Daniel Weber, Siyuan Zhang +9
The rational design of hydrogen evolution reaction (HER) electrocatalysts which are competitive with platinum is an outstanding challenge to make power-to-gas technologies economic…
Direct Observation of Interface and Nanoscale Compositional Modulation in Ternary III-As Heterostructure Nanowires
Sriram Venkatesan, Morten H. Madsen, Herbert Schmid +3
Straight, axial InAs nanowire with multiple segments of GaInAs were grown. High resolution X-ray energy-dispersive spectroscopy (EDS) mapping reveal the distribution of group III a…
