[Use of rigid gas permeable contact lenses].

Klinika oczna, 1994
By application of contact lenses destined for a extended wearing, for preservation of a normal structure and metabolism of the cornea a considerable permeability of the contact lens for oxygen is necessary (Dk/L 75-80). The actually most popular in the world soft contact lenses have no such parameters.

Biopolymer‐Coated Paper Composites for Sustainable Packaging

Asia-Pacific Journal of Chemical Engineering, EarlyView.
ABSTRACT Conventional plastic packaging, though dominant in food and flexible applications, poses serious environmental concerns due to its persistence and limited recyclability. To address this challenge, this study develops bio‐based coated paper composites as sustainable alternatives. Paper, while biodegradable, lacks adequate barrier properties. To

Optimized Selenium‐Doped Nanocomposites for Enhanced Polymer Gel Performance in Permeability Reduction

Asia-Pacific Journal of Chemical Engineering, EarlyView.
ABSTRACT Excessive water production in mature oil fields necessitates robust shut‐off treatments, yet conventional polymer gels often fail under high‐temperature and high‐salinity conditions. This study aims to enhance gel thermal stability and mechanical strength by incorporating selenium‐doped Ag/AgO–ZnO nanocomposites synthesized via a novel green ...

Drug‐coated balloons: From conventional designs to next‐generation innovations in vascular therapy

BMEMat, EarlyView.
This review traces the evolution of drug‐coated balloons (DCBs) from conventional designs to next‐generation platforms. We highlight innovations in balloon engineering, coating technologies, and therapeutic agents that enhance localized drug delivery while addressing challenges in efficiency, safety, and biocompatibility for vascular and emerging non ...
