(2024-12-19)The use of entomopathogenic fungi as biocontrol agents in agricultural pest management offers a promising alternative to chemical pesticides, aligning with the increasing global emphasis on sustainable farming practices. ... -
Mechanistic Studies of Hydrogen Recombination and Water Formation on Palladium Surfaces
(2024-12-19)In heterogeneous catalysis, one of the major challenges is to determine which microscopic processes are of importance for the reaction to occur with desired activity and selectivity. Efforts towards a fundamental understanding ... -
Towards a new view of the photospheric magnetic field with the Polarimetric and Helioseismic Imager on Solar Orbiter
(2024-12-19)Accurately determining the magnetic flux through the solar surface is incredibly important to understanding the dynamics of the Sun and its atmosphere. The magnetic field provides energy for heating the higher layers of ... -
CO2-Bindung in landwirtschaftlichen Böden durch Humusaufbau - Untersuchungen zur Teilnahmebereitschaft landwirtschaftlicher UnternehmerInnen an Humusprogrammen
(2024-12-19)In order to counteract climate change, it is necessary to reduce greenhouse gas emissions and the existing concentration of greenhouse gases in the atmosphere. Agricultural soils have a great potential to store carbon ... -
Measurement of the tt̄γ production cross section with the ATLAS experiment at √ s = 13 TeV using the full Run 2 data set
(2024-12-19)With Run 1 of the LHC, an unequalled top-quark factory started its operation. While during Run 1 the focus was on tt̄ measurements, the unprecedented size of the ATLAS Run 2 data set of 140 fb −1 allows for precise ... -
Pallada-Electrocatalyzed Non-Directed C–H Alkenylation and Double C–H Arylation
(2024-12-19)The merger of electrooxidation and transition metal-catalyzed C–H activation has emerged as an increasingly viable platform in molecular syntheses that can avoid stoichiometric chemical redox agents and circuitous functional ... -
Domain decomposition for optimal transport and localized optimality conditions
(2024-12-19)Optimal transport (OT) is a fundamental tool in the study of the space of probability measures. Several algorithmic breakthroughs, such as the Sinkhorn algorithm, have allowed practicioners to solve the OT problem ... -
