Here, we describe the in-plane patterning of thin films of poly(acrylic acid) (PAA) within microfluidic channels by crosslinking with metal cations. The patterned polymer and embedded metal ions (Pb, Ba, Zn, Pd, Cu, La, or Ho) are a platform for the rapid “on-chip” growth of patterned metallic and semiconductor nanoparticles; these particles, in turn, serve as catalysts for electroless depositi...

showing the occurrence of glass/rubber transition in bovine serum albumin (a globular protein) atlow moisture levels and the occurrence of maillard crosslinking in gelatin in previous works, the importanceof the state of glass or rubber of bsa on the rate and extent of polymerisation, protein solubility, colour andsds page patterns in the presence and absence of ascorbic acid, diketogulonic aci...

The 3D encapsulation of cells within hydrogels represents an increasingly important and popular technique for culturing cells and towards the development of constructs for tissue engineering. This environment better mimics what cells observe in vivo, compared to standard tissue culture, due to the tissue-like properties and 3D environment. Synthetic polymeric hydrogels are water-swollen network...

A concept of patternable top-coats dedicated to directed self-assembly high-? block copolymers is detailed, where the design enables a crosslinking reaction triggered by thermal or photo-activation. Nanostructured BCP areas with controlled domains orientation are selected through straightforward top-coat lithography step unique integration pathways. Additionally, crosslinked nature material sup...

An elaborate surface-crosslinking method was introduced to enhance the low absorbency under load (AUL) and liquid permeability of itaconic-acid-based superabsorbent polymer (SAP). The effects reaction parameters absorption properties SAP were investigated. increase in content distilled water 1,4-butanediol used as solution improved AUL SAP, whereas an resulted a sharp decrease centrifuge retent...

Focusing on the challenge of non-biodegradable plastics replacement, we propose a design for peroxide-initiated crosslinking biodegradable poly(ε-caprolactone) (PCL) and renewable cellulose nanocrystals (CNCs) bionanocomposites. An industrially scalable water-assisted reactive melt-processing (REx) is studied to explore hypothesis synergy between simultaneous effects water improving CNC dispers...

This article reports the effects of gamma irradiation (dose ranges 0.1-10 kGy from 60Co source) on the characteristics of solid gelatin and the physico-mechanical, microstructural and bioactive properties of the scaffold prepared from irradiated gelatin solution. FTIR, intrinsic viscosity, bloom strength, thermal properties, SEM, tensile properties, water uptake ability and antimicrobial activi...
