Contrasting functional responses of benthic and hyporheic stream biofilms to light availability and macronutrient stoichiometry

open access: yesLimnology and Oceanography, EarlyView.
Abstract Nutrient dynamics in headwater streams are governed by benthic and hyporheic biofilms, with carbon (C) : nitrogen (N) : phosphorus (P) ratios driving the heterotrophic microbial biofilm development through nutrient limitation. Furthermore, heterotrophic responses to changes in C : N : P ratios are probably modulated by autotrophic responses to

Self‐Assembly Pathway Influence on Dehydropeptide‐Based Gel Properties and Drug Release

open access: yesMacromolecular Bioscience, EarlyView.
In this work, it is explored how the gelation conditions affect the morphology, mechanical properties, and drug release of dehydropeptide‐based gels. The naphthalene‐capped dehydropeptide forms a crystal structure with a pore diameter of ≈4.08 Å. Gelation conditions can influence gel stiffness by nearly three orders of magnitude, in which the assembly ...

A Brief History of Plastic Additives. Part 1: Antioxidants

open access: yesMacromolecular Materials and Engineering, EarlyView.
The development of suitable antioxidants has been a decisive element for the success of plastics in particular in the field of polyolefins. Sterically hindered phenol structures, amines, and sulfur‐containing products including multifunctional substances comprise today´s commercial range. Stabilizers based on renewable resources and tailor‐made systems

Lauric Acid Based Composite Phase Change Materials Form‐Stabilized with Highly Crosslinked Polymer for Thermal Energy Storage

open access: yesMacromolecular Materials and Engineering, EarlyView.
The design of a composite phase change material (PCM) suitable for low‐temperature thermal energy storage (TES) systems is performed. For this purpose, highly cross‐linked polymer frameworks with a surface area of ​​76.26 m2 g−1 are prepared by Friedel‐Crafts alkylation reaction.
