Wavelength tunable 10-GHz 3-ps pulse source using a dispersion decreasing fiber-based nonlinear optical loop mirror [PDF]
, 2004 We experimentally demonstrate the use of a dispersion decreasing fiber (DDF)-based nonlinear optical loop mirror (NOLM) for the generation of wavelength tunable soliton-like pulses at a repetition rate of 10 GHz.

ChemSusChem, Volume 18, Issue 6, March 15, 2025.Novel organic solvents with an unmodified carbohydrate core were synthesised both from D‐xylose and directly from biomass and were successfully used as reaction media for lipase biocatalysts to synthesise aliphatic and aromatic polyesters. Abstract The use of organic solvents in academic research and industry applications is facing increasing ...

Cooperativity in Dinuclear Complexes With Redox‐Active Guanidine Ligands Aligned in a Ring
European Journal of Inorganic Chemistry, EarlyView.The introduction of designed organic linkers between two redox‐active diguanidine units induces cooperative effects in dinuclear metal complexes. In this work, the differences in the electronic structures of dinuclear cobalt and copper complexes with respect to the corresponding individual metal complexes are analyzed.
