Perylene bisimide J-aggregates in a polymer matrix: controlling self-assembly and fluorescence properties
The self-assembly process of tetraphenoxy-substituted perylene bisimide dyes into J-aggregates via hydrogen bonds is investigated in three different polymer matrices resulting in solid-state materials with fluorescence quantum yields up to 28%.
Extremely durable supercapacitor enabled by disordered porous carbon with a capacity retention up to 60 000 cycles
Porous carbon materials have been prepared through a salt template method. The as-fabricated supercapacitors show an excellent cycling stability. These supercapacitors hold great potential for application in the field of energy storage.
Development of a novel polyelectrolyte complex nanocomposite of modified chitosan and karaya gum for co-delivery of 5-fluorouracil and curcumin for cancer therapy
A pH-responsive polyelectrolyte complex of trimethylchitosan and carboxymethylkaraya gum containing silver nanoparticles has been developed as a matrix material for co-delivery of the drugs, 5-fluorouracil and curcumin.
Cellulose-based bioactive material and turmeric-impregnated flexible and biocompatible scaffold for bone tissue engineering applications
Cellulose-based cotton fabric impregnated with a bioactive material and turmeric acts as a flexible, biocompatible, eco-friendly, and cost-effective material for bone regeneration applications.
Reversible photomechanical actuators with liquid crystal polymer graphene oxide nanocomposites
This study quantifies the photomechanical actuation in LC242 nanocomposites doped with azo dye and graphene oxide. Optimized doping and UV curing achieve a 35° photo-induced bend with rapid response, advancing applications in smart materials.
Nitrogen doped carbon quantum dots: a multifaceted carbon nanomaterial that interferes in an amyloid-forming trajectory
LAdN-CQDs have been used to inhibit fibril formation, display biocompatibility, reduce reactive oxygen species, and safeguard against apoptosis, indicating promise in neuroprotection.
