Energy conversion in isothermal nonlinear irreversible processes - struggling for higher efficiency

open access: yes, 2017
First we discuss some early work of Ulrike Feudel on structure formation in nonlinear reactions including ions and the efficiency of the conversion of chemical into electrical energy.

Evolutionary tradeoff and equilibrium in an aquatic predator-prey system [PDF]

open access: yes, 2004
Due to the conventional distinction between ecological (rapid) and evolutionary (slow)timescales, ecological and population models to date have typically ignored the effects of evolution.

Lignin precursors enhance exolaccase-started humification of bisphenol A to form functional polymers

open access: yesEco-Environment & Health, 2023
Humification plays a significant role in converting phenolic pollutants and forming heterogeneous polymers, but few studies have been performed to investigate exolaccase-started humification (ESH).

Enzymatic degradation of biopolymers in amorphous and molten states: mechanisms and applications

open access: yesFEBS Open Bio, EarlyView.
This review explains how polymer morphology and thermal state shape enzymatic degradation pathways, comparing amorphous and molten biopolymer structures. By integrating structure–reactivity principles with insights from thermodynamics and enzyme engineering, it highlights mechanisms that enable efficient polymer breakdown.
