Tribological behavior of lubricant-impregnated porous polyimide
Friction, 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.

Structure and Dynamics of Solvated Polymers near a Silica Surface: On the Different Roles Played by Solvent [PDF]
, 2018 Whereas it is experimentally known that the inclusion of nanoparticles in hydrogels can lead to a mechanical reinforcement, a detailed molecular understanding of the adhesion mechanism is still lacking.

BRANCHED POLYMERS ON BRANCHED POLYMERS [PDF]
Modern 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

Polymer Release out of a Spherical Vesicle through a Pore
, 1998 Translocation of a polymer out of curved surface or membrane is studied via mean first passage time approach. Membrane curvature gives rise to a constraint on polymer conformation, which effectively drives the polymer to the outside of membrane where the

Colloid-Induced Polymer Compression [PDF]
, 2002 We consider a model mixture of hard colloidal spheres and non-adsorbing polymer chains in a theta solvent. The polymer component is modelled as a polydisperse mixture of effective spheres, mutually noninteracting but excluded from the colloids, with ...

HYDRAULIC CONDUCTIVITY AND SOIL-WATER DIFFUSION AND ITS RELATIONSHIP TO GYPSUM AND CLAY CONTENT OF SOILS TREATED WITH PEAT-MOSS AND POLYMER [PDF]
مجلة الأنبار للعلوم الزراعيةAn experiment was conducted to estimate hydraulic conductivity, soil-water diffusion, and its relationship to gypsum and clay content of soils treated with peat-moss and polymer. Two soils were used, the first containing 410 gm.

Reciprocal control of viral infection and phosphoinositide dynamics
FEBS Letters, EarlyView.Phosphoinositides, although scarce, regulate key cellular processes, including membrane dynamics and signaling. Viruses exploit these lipids to support their entry, replication, assembly, and egress. The central role of phosphoinositides in infection highlights phosphoinositide metabolism as a promising antiviral target.
