POLYMERIC FILMSAMINO ACIDSANIONSMATERIALSMOLECULAR WEIGHTNYLONPEPTIDESPIEZOELECTRICITYPLASTICIZERSA 33-month project was undertaken to study piezoelectricity in low, odd nylons; odd, odd nylons; polyureas; and polypeptides. The commercially available polypeptides poly(L alanine), poly(L valine), and poly(...
Development of an UV rolling system for fabrication of micro/nano structure on polymeric films using a gas-roller-sustained seamless PDMS moldRoller imprinting is one of the most effective methods to fabricate polymeric plate components with nanostructures on the surface. In this study, a gas-bag ...
Synthetic ultrathin structures have the potential for use in the development of smart biomaterials and devices inspired by the functions of cytoplasmic membranes. Polymeric ultrathin films (referred to as nanosheets and also known as nanofilms or nanomembranes) are a new class of polymeric ...
The membranes were prepared by grafting tertiary amines onto polyethylene films. After grafting, the membranes were made ionic in character by conversion to the corresponding hydrochloride or by quaternizing with 1-bromobutane. Evaluation demonstrated the feasibility of preparing membranes having acceptable ...
polymeric gel electrolytes. Such batteries exhibit an energy density of 1323 Wh L−1at the pouch cell level. Moreover, the lithium sulfide-based anode-free cell chemistry endows intrinsic safety thanks to a lack of uncontrolled exothermic reactions of reactive oxygen and excess Li inventory....
of hard-shell gelatin capsules is a benefit for such dosage forms. To alter drug release by using polymeric films, there are various concerns, such as choosing a polymer with the required capabilities to unwind and enlarge in the gastric system and complex processes in preparing polymeric films ...
Superficial fungal diseases of the skin and nails are an increasingly common occurrence globally, requiring effective topical treatment to avoid systemic adverse effects. Polymeric nanoparticles have demonstrated sustained and effective drug delivery in a variety of topical formulations. The aim of this pro...
Colon-targeted drug delivery systems (CTDDSs) could be useful for local treatment of inflammatory bowel diseases (IBDs). In this study, various interpolyelectrolyte complexes (IPECs), formed between ...
Rectangular tunnels with or without fins/grooves are made of metal sheets or polymeric materials either in separate channels or in double/multipass designs (Figure 2). They are used in all types of PV/T collectors, because the flat-plate surfaces can be easily integrated with PV modules. Addit...
In the drug reservoir compartment, the drug can be in the form of a solution, suspension, gel or be dispersed in a solid polymer matrix. The hypoallergenic adhesive polymer can be also be applied as an outer surface polymeric membrane, which needs to be compatible with the drug. Matrix-...
