Preparation and Surface Characterization of Chitosan-Based Coatings for PET Materials

open access: yesMolecules, 2023
Poly(ethylene terephthalate)—PET—is one of the most frequently used polymers in biomedical applications. Due to chemical inertness, PET surface modification is necessary to gain specific properties, making the polymer biocompatible. The aim of this paper

Utilization of Chlorella vulgaris to Fixate a High Concentration of Carbon Dioxide in a Compost-based Medium

open access: yesInternational Journal of Technology, 2016
Massive use of fuels by industry increase carbon dioxide (CO2) emissions significantly. Chlorella vulgaris (C. vulgaris) is well known for its ability to fixate CO2 and synthesize it to a lipid. As industry usually emits high concentrations of CO2, it

Covalently Binding the Photosystem I to Carbon Nanotubes

open access: yes, 2009
We present a chemical route to covalently couple the photosystem I (PS I) to carbon nanotubes (CNTs). Small linker molecules are used to connect the PS I to the CNTs.

Specific heat anomaly in the d-density wave state and emergence of incommensurate orbital antiferromagnetic order

open access: yes, 2001
We study the effect of finite chemical potential on the d-density wave state that has been proposed to explain the pseudogap phenomena in underdoped cuprates. We find that the specific heat anomaly at the transition temperature, below which the d-density
