Temporal pulse shaping aspects of refractive X-ray lenses. [PDF]

open access: yesJ Synchrotron Radiat
This work investigates the temporal effects of refractive X‐ray lenses on ultra‐short pulses from X‐ray free‐electron lasers. Using both a full Fresnel theory model and a simplified ray‐tracing approach, the paper analyzes the pulse elongation and spatio‐temporal distortions introduced by these focusing optics.Refractive X‐ray lenses are frequently ...

Naturens trøst og trøstens natur

open access: yesNordisk Tidsskrift for Helseforskning, 2023
Dette essayet er en undring om å finne trøst i naturen. Fortellinger brukes for å få frem ulike aspekter ved fenomenet trøst både i og utenfor naturen, slik vi kan møte det i sorg og annen lidelse.

Direct Synthesis of Allyl Amines with 2‐Nitrosulfonamide Derivatives via the Tsuji‐Trost Reaction

open access: yesChemistryOpen, 2021
The Tsuji‐Trost Reaction is a palladium‐catalysed allylation of nucleophiles that consists in the reaction of a nitrogen, carbon or oxygen‐based nucleophiles with an allylic substrate bearing a leaving group. Here we present the use of 2‐nitrosulfonamide

Calculation, normalization and perturbation of quasinormal modes in coupled cavity-waveguide systems [PDF]

open access: yes, 2014
We show how one can use a non-local boundary condition, which is compatible with standard frequency domain methods, for numerical calculation of quasinormal modes in optical cavities coupled to waveguides.

Catalytic Enantioselective Synthesis of N-C Axially Chiral N-(2,6-Disubstituted-phenyl)sulfonamides through Chiral Pd-Catalyzed N-Allylation

open access: yesMolecules, 2022
Recently, catalytic enantioselective syntheses of N-C axially chiral compounds have been reported by many groups. Most N-C axially chiral compounds prepared through a catalytic asymmetric reaction possess carboxamide or nitrogen-containing aromatic ...

On the theory of coupled modes in optical cavity-waveguide structures [PDF]

open access: yes, 2017
Light propagation in systems of optical cavities coupled to waveguides can be conveniently described by a general rate equation model known as (temporal) coupled mode theory (CMT).
