Growth Strategy of Circular Startups

open access: yesBusiness Strategy and the Environment, EarlyView.
ABSTRACT Circular startups (CSUs) play a crucial role in the circular transition by developing circular business models (CBMs) that minimise resource use and narrow material and energy loops. However, empirical research on how CBMs shape growth strategies and how ecosystems enable or constrain scaling remains limited.

Action of Betulinic Acid in the Inhibition of Efflux Pump NorA in Staphylococcus aureus Strains: In Vitro and In Silico Approaches

open access: yesChemistry &Biodiversity, EarlyView.
ABSTRACT Antibiotic resistance poses a serious challenge to public health, particularly in the case of Staphylococcus aureus, a Gram‐positive bacterium that employs multiple resistance mechanisms, including efflux pumps such as NorA, which extrude antimicrobial compounds from the cell and reduce antibiotic efficacy. Therefore, the search for substances

Bifunctional Reduced Graphene Oxide Derivatives for PFOA Adsorption

open access: yesChemistryEurope, EarlyView.
A bifunctional graphene‐based material is developed for selective PFAS adsorption from water. Thermally reduced graphene oxide is modified with quaternary ammonium groups and fluorinated chains, promoting electrostatic and fluorine–fluorine interactions. Surface functionality is characterized by X‐ray photoelectron spectroscopy, atomic force microscopy,

Exploring Indium Teflates: From Neutral In(OTeF5)3(THF)3 to Anionic Complexes [In(OTeF5)4(THF)2]– and [In(OTeF5)6]3–

open access: yesChemistryEurope, EarlyView.
The study examines the coordination chemistry of indium teflate complexes, showing the progression from [In(OTeF5)3(THF)3] to the anionic species [In(OTeF5)4(THF)2]– and [In(OTeF5)6]3–. Systematic ligand substitution and anion formation reveal increasing teflate coordination, highlighting structural evolution, Lewis acidity modulation, and ...

Aspects of the Requirements of ISO 15263.4 and the Design and Development of Bicycle Racks [PDF]

open access: yes
There is currently interest in developing safety standards for bicycle racks for cars. A draft international standard (ISO 15263.4) has been developed. However, there have been many objections to the proposals and a redraft has been made.
