Mechanisms and factors affecting the removal of minocycline from aqueous solutions using graphene-modified resorcinol formaldehyde aerogels

open access: yesScientific Reports, 2023
In recent years, concerns about the presence of pharmaceutical compounds in wastewater have increased. Various types of residues of tetracycline family antibiotic compounds, which are widely used, are found in environmental waters in relatively low and ...

Mechanochemically accessing a challenging-to-synthesize depolymerizable polymer

open access: yesNature Communications, 2023
Polymers with low ceiling temperatures (Tc) are highly desirable as they can depolymerize under mild conditions, but they typically suffer from demanding synthetic conditions and poor stability.

X-ray spectrometry applied for determination of linear attenuation coefficient of polymer-based samples as radiologically tissue-equivalent materials

open access: yesBrazilian Journal of Radiation Sciences, 2023
In this work we obtained experimental linear attenuation coefficients of polymer-based samples at diagnostic imaging energy range (15-150 keV) for eleven formulations candidates for tissue-equivalent materials (TEMs).

BRANCHED POLYMERS ON BRANCHED POLYMERS [PDF]

open access: yesModern Physics Letters A, 1996
We study an ensemble of branched polymers which are embedded on other branched polymers. This is a toy model which allows us to study explicitly and in detail the reaction of a statistical system to its underlying geometrical structure, a problem of interest in the study of the interaction of matter and quantized gravity. We find a phase transition at

Responsive materials based on coordination bonds

open access: yesResponsive Materials, 2023
Responsive materials can respond to different external stimuli by changing their chemical or/and physical properties, thus being useful for various applications such as drug delivery, bioimaging, actuators, and sensors. A common strategy for constructing

Polymers Pushing Polymers: Polymer Mixtures in Thermodynamic Equilibrium with a Pore [PDF]

open access: yesBiophysical Journal, 2012
We investigate polymer partitioning from polymer mixtures into nanometer size cavities by formulating an equation of state for a binary polymer mixture assuming that only one (smaller) of the two polymer components can penetrate the cavity. Deriving the partitioning equilibrium equations and solving them numerically allows us to introduce the concept ...

Tribological behavior of lubricant-impregnated porous polyimide

open access: yesFriction, 2023
Porous materials impregnated with lubricants can be used in conditions where limited lubricant is desirable. In this work, three porous polyimides (PPI) with different densities were prepared.
