the aim of this study was to investigate the barrier properties of cellulose nanocrystals-pvananocomposites. nanocomposite films with different filler loading levels (3, 6, 9 and 12% by wt) weredeveloped by solvent casting method. the effect of cellulose nanocrystals on the barrier properties ofthe nanocomposites was studied. to this end, moisture absorption, water vapor permeability (wvp),oxyg...

A novel synthesis method of partially crosslinking a polymer solution prior to casting, has been successfully developed for the preparation solvent-tolerant nanofiltration (STNF) membranes. STNF merges solvent resistant (SRNF) with aqueous nanofiltration. The feed consists mixture solvent(s) and water, requiring membrane both high water permeability stability. In this work, epoxy resins are pro...

Introduction: As the ability to repair cartilage tissue in body is limited, finding a suitable method for cartilage regeneration has gained the attention of many scholars. For this purpose, scaffold structure and morphology, along with cell culture on it, can be a novel method to treat cartilage injuries, osteoarthritis. Methods: In this study, polyhydroxybutyrate (PHB) is selected as the scaf...

Chitosan/gelatin and chitosan/gelatin/zeolite films prepared by solvent casting method are impregnated with a mixture of thymol carvacrol using green solvent, supercritical carbon dioxide at 35 °C 30 MPa, during 18 h. Proposed enables preparation biocompatible biodegradable blends strong antioxidant antibacterial activity, whereby amounts loaded thymol/carvacrol (TC) in the range from 3.3% to 6...

The current work explores the potential use of commercial Chinese bayberry tannin (BT) to develop antioxidant PVA-based films using solvent casting process for packaging applications. effect BT concentration on opacity, water resistance and capacity resulting was investigated. Properties like tensile strength, thermal behavior, morphological aspects were also characterized. experimental results...

A new opacity correction approach for oversampled volume ray casting is introduced. While the only existing opacity correction method in the literature is based on the assumption of dataset homogeneity, the new opacity correction method introduced in this paper is a faster, generalized voxel-by-voxel approach which does not assume dataset homogeneity. The new opacity correction avoids the datas...

Abstract Poly(vinylidene fluoride) (PVDF) ultrafiltration (UF) membrane was prepared by vapor and non-solvent-induced phase separation (VNIPS) process, the relationships between preparation conditions, behaviors structures were discussed. The diagram generated cloud point titration, effects of environmental relative humidity, air exposure time casting solution temperature on structure performan...

Polycaprolactone (PCL) is a widely applied biomaterial in bone tissue engineering (BTE) due to its superior mechanical properties and biodegradability. However, the high hydrophobicity low cell adhesion of PCL show limited interactions. Herein, we prepared porous PCL/DBP composites with improved through addition demineralized powder (DBP). Three-dimensional scaffolds were fabricated by mixing v...

Recent studies show that osmotically driven membrane processes may be a viable technology for desalination, water and wastewater treatment, and power generation. However, the absence of a membrane designed for such processes is a significant obstacle hindering further advancements of this technology. This work presents the development of a high performance thin-film composite membrane for forwa...
