Identification of low-valent iron-porphyrins: Electronic structure and reactivity towards CO2 reduction
(2022-01-25)
The need to close the carbon cycle becomes urgent as concentration of CO2 in the earth atmosphere increases exponentially. Electrochemically-mediated conversion of CO2 into biofuels is a possible ...
Structural and electronic decoupling of a large organic molecule from a metal surface by a single layer of hexagonal boron nitride
(2022-02-21)
In the present work, the ability of one single layer of hexagonal boron nitride (hBN) to decouple the organic molecule 3,4,9,10-perylene tetracarboxylic dianhydride (PTCDA) from an underlying Cu(111) surface was investigated. ...
Efficient approximations for the ab initio calculation of nuclear magnetic resonance shielding tensors
(2022-02-02)
Nuclear magnetic resonance (NMR) spectroscopy is an essential analytic technique in chemical, pharmaceutical, and biomedical research and materials sciences. The information that NMR provides about the molecular structure ......

(2022-02-21)
Im Rahmen der vorliegenden Arbeit ist es gelungen, zahlreiche neue Radikalkationensalze mit demselben Anion, dem [Mo6Cl14]2--Cluster, zu erhalten und zu charakterisieren. Der [Mo6
Pnictogenide and Chalcogenide Zintl Phases via Solid State and Solvothermal Syntheses
(2022-09-08)
This work concentrated on the synthesis of new Zintl phases, especially focusing on the synthesis of new polyarsenides and chalcogenides. Through high temperature synthesis, the compounds Ba3As4, Ba3As2O and K3Ba7(As3)3O ...
Atomic-scale friction study on Au(111) under electrochemical conditions
(2022-09-14)
In this study, lateral force microscopy (LFM) has been employed to investigate the frictional behavior on the surface of an electrode and the role of adsorbates, which correlates with interactions occurring at the interface. ...
In Silico Understanding of the Hydrogen Bond Network in Organic Solvent Mixtures
(2022-05-20)
In the framework of green chemistry, it is fundamental to further investigate the intermolecular interactions that define the dynamics and structure of liquids and their mixtures. Among those, the hydrogen bond in particular ...
Synthese, Eigenschaften und Anwendung symmetrischer Anilinosquaraine als Komponente in Photodioden
