Journal ArticleDOI
Mass‐Production of Mesoporous MnCo2O4 Spinels with Manganese(IV)‐ and Cobalt(II)‐Rich Surfaces for Superior Bifunctional Oxygen Electrocatalysis
Wenhai Wang,Long Kuai,Wei Cao,Marko Huttula,Sami Ollikkala,Taru Ahopelto,Ari-Pekka Honkanen,Simo Huotari,Mengkang Yu,Baoyou Geng +9 more
TL;DR: The prominent bifunctional activity shows that MnCo2 O4 could be used in metal-air batteries and/or other energy devices and the surface state engineering may open a new avenue to optimize the electrocatalysis performance of electrode materials.
Journal ArticleDOI
Microscopic structure of water at elevated pressures and temperatures
Christoph J. Sahle,Christian Sternemann,Christian Schmidt,Susi Lehtola,Sandro Jahn,Laura Simonelli,Simo Huotari,Mikko Hakala,Tuomas Pylkkänen,Alexander Nyrow,Kolja Mende,Metin Tolan,Keijo Hämäläinen,Max Wilke +13 more
TL;DR: According to the simulations, distortions of the hydrogen-bond network increase dramatically when temperature and pressure increase to the supercritical regime and the average number of hydrogen bonds per molecule decreases.
Journal ArticleDOI
Multiple-element spectrometer for non-resonant inelastic X-ray spectroscopy of electronic excitations
Roberto Verbeni,Tuomas Pylkkänen,Tuomas Pylkkänen,Simo Huotari,Laura Simonelli,György Vankó,Keith Martel,C. Henriquet,Giulio Monaco +8 more
TL;DR: A multiple-analyser-crystal spectrometer for non-resonant inelastic X-ray scattering spectroscopy installed at beamline ID16 of the European Synchrotron Radiation Facility is presented.
Journal ArticleDOI
Direct tomography with chemical-bond contrast
Simo Huotari,Simo Huotari,Tuomas Pylkkänen,Tuomas Pylkkänen,Roberto Verbeni,Giulio Monaco,Keijo Hämäläinen +6 more
TL;DR: This work introduces a new hard-X-ray spectroscopic tomography with a unique sensitivity to light elements, and applies the method to acquire the 3D structure and map the chemical bonding in selected samples relevant to materials science.
Journal ArticleDOI
Improving the performance of high-resolution X-ray spectrometers with position-sensitive pixel detectors.
Simo Huotari,Gy. Vankó,F. Albergamo,Cyril Ponchut,H. Graafsma,C. Henriquet,Roberto Verbeni,Giulio Monaco +7 more
TL;DR: A dispersion-compensation method to remove the cube-size effect from the resolution function of diced analyzer crystals using a position-sensitive two-dimensional pixel detector is presented, allowing a substantial increase in the resolving power without any loss of signal intensity.
