Bond-selective and surface-site-specific dissociation of methane on platinum

I present a molecular beam study of methane dissociation on differ-ent surface sites of several platinum single crystal surfaces (Pt(111), Pt(211), Pt(210), Pt(110)-(2x1)). The experiments were performed in a molecular beam/surface-science apparatus that c ...

Angle-multiplexed all-dielectric metasurfaces for broadband molecular fingerprint retrieval

Hatice Altug, Andreas Tittl, Aleksandrs Leitis, Bang Hyun Lee, Mingkai Liu

Infrared spectroscopy resolves the structure of molecules by detecting their characteristic vibrational fingerprints. Subwavelength light confinement and nanophotonic enhancement have extended the scope of this technique for monolayer studies. However, cur ...

Leather-Promoted Transformation of Glucose into 5-Hydroxymethylfurfural and Levoglucosenone

Paul Joseph Dyson, Felix Daniel Bobbink, Florent Menoud, Zhangjun Huang

The search for efficient catalysts frequently leads to new homogeneous and heterogeneous catalysts of increasing complexity, and sometimes common, natural, or hybrid natural/synthetic materials that could be used in catalysis are overlooked. For example, t ...

Statics and dynamics of multivalley charge density waves in Sb (111)

Davide Campi, Daniele Dragoni

Charge density waves (CDWs), periodic modulations of the charge density, are among the most abundant and non-trivial ordered phases in condensed matter. Here we demonstrate the occurrence of multi-valley charge density waves (MV-CDW) on the semimetal Sb(11 ...

Non-equilibrium dynamics of di-platinum complexes and molecular dyes in solution: Insights from transient absorption and two-dimensional Fourier transform spectroscopy

Lars-Hendrik Mewes

Unraveling the interplay between electronic- and vibrational degrees of freedom on the earliest time scales of physical, chemical and biological processes is crucial to gaining insight into the mechanisms that govern the world around us, since it is during ...

UV and IR Spectroscopy of Transition Metal–Crown Ether Complexes in the Gas Phase: Mn2+(benzo-15-crown-5)(H2O)0–2

Thomas Rizzo, Yoshiya Inokuchi

Ultraviolet photodissociation (UVPD) and IR–UV double-resonance spectroscopy are performed for bare and microhydrated complexes of Mn2+(benzo-15-crown-5), Mn2+(B15C5)(H2O)n (n = 0–2), under cold (∼10 K) gas-phase conditions. Density functional theory (DFT) ...

Effect of annealing temperature on the performance of printable carbon electrodes for perovskite solar cells

Mohammad Khaja Nazeeruddin, Iwan Zimmermann, Zubair Ahmad

Perovskite solar cells (PSCs) with mesoporous TiO2 electron transport layers have reached > 22% efficiency at laboratory scale ( < 1 cm(2)), however, these layers are fabricated using spin-coating, which is not conducive to large-scale or high throughput f ...

Koopmans Meets Bethe-Salpeter: Excitonic Optical Spectra without GW

Nicola Marzari, Nicola Colonna, Paolo Umari

The Bethe Salpeter equation (BSE) can be applied to compute from first-principles optical spectra that include the effects of screened electron hole interactions. As input, BSE calculations require single-particle states, quasiparticle energy levels, and t ...
