From planes to bowls: photodissociation of the bisanthenequinone cation
, 2018 We present a combined experimental and theoretical study of the photodissociation of the bisanthenequinone (C28H12O2) cation, Bq+. The experiments show that, upon photolysis, the Bq+ cation does not dehydrogenate, but instead fragments through the ...

Designing for Degradation: Transient Devices Enabled by (Nano)Cellulose
Advanced Materials, EarlyView.Recent progress in transient devices enabled by (nano)cellulosic materials is reviewed. Transiency mechanisms, advantages of nanocelluloses, and a suite of applications are discussed. A circular thinking approach coupled with life cycle assessment is applied to critically revisit the potential, advantages, and challenges of nanocellulose‐enabled ...

The simulation of interquinone charge transfer in a bacterial photoreaction center highlights the central role of a hydrogen-bonded non-heme iron complex [PDF]
, 1954 We consider electron transfer between the quinones QA and QB, one of the final steps in the photoinduced charge separation in the photoreaction center of Rhodobacter sphaeroides.

Advanced Materials, EarlyView.A novel one‐shot integration electropolymerization (OSIEP) method is developed as a breakthrough on the intricate photolithographic steps, enabling to compress all processes from synthesis to channel integration in one‐shot manufacturing. The specially designed dual bipolar electrodes provide the targeted depositions of poly(3,4‐ethylenedioxythiophene)

“Breast is best”… until they say so
Frontiers in Sociology, 2023 In this autoethnographic article, I discuss the consequences of being exposed to two competing breastfeeding discourses during my first mothering experience—the “self-regulated dyad” and the “externally regulated dyad” discourse.

Stability of steady state solutions in a predator-prey model with density-dependent diffusion [PDF]
arXiv, 2020 In this note we present a study of the solutions associated to a particular spatial extension of the Rosenzweig-MacArthur model for predator and prey. The analysis presented here shows that positive steady state solutions emerge via a transcritical bifurcation mechanism, in accordance with the insight obtained from previous numerical and analytical ...
