An electrically conducting reversible adhesive with conductivity up to 2.9 × 10 ⁵ S m ⁻¹ and lap shear strength of up to 1.5 MPa is presented. The reversibility of the glue enables debonding of surfaces on exposure to alkaline media. The adhesive comprises polyelectrolyte‐stabilized nanoparticles synthesized by emulsion polymerization and silver nanoparticles as conductive filler. The conductivity of these formulations is comparable to, or exceeds, that of commercially available conductive adhesives, while their mechanical performance is consistent with typical water‐based adhesive systems. Adhesion is reversed by immersing the bonded joints at pH 14. By heating to 85°C and stirring the solution (500 rpm), the debonding time can be reduced to ∼30 min or less. Separation can also be achieved at 85°C at pH 7. Short debonding times can also be achieved at room temperature by using acetone, a recognized green solvent. This electronically conducting reversible adhesive therefore presents a great opportunity to improve the reuse or recycling of electronic components.

A single-formulation water-based and industrially scalable reversible adhesive was prepared from polyelectrolyte emulsions containing clays.

Molecularly imprinted polymer nanoparticles are utilised to achieve the rapid, ultrasensitive detection of cardiac troponin I in human interstitial fluid.

Chitosan is widely explored in the field of biomedicine due to its abundance and reported properties, including biocompatibility, biodegradability, non-toxicity, mucoadhesion, and anti-microbial activity. Although our understanding of the immune response to chitosan has evolved, confusion remains regarding whether chitosan is a pro- or anti-inflammatory biomaterial. Tackling this knowledge gap is essential for the translation of chitosan-based biomaterials to clinical use. Herein, we provide an overview of the immune responses to chitosan, exploring the roles of endotoxin contamination and physiochemical properties in immunomodulation. Ultimately, this literature review concludes that various physiochemical properties, including molecular weight, degree of deacetylation and polydispersity, endotoxin contamination, and cellular environment, interplay in the complex process of chitosan immunomodulation, which can lead to both pro- and anti-inflammatory effects.

This study explores the role of diffusion in creating instabilities in the Bruk Temkin-Gorodsky Novakovic (BT-GN) oscillatory carbonylation reaction network. Stoichiometric network analysis and numerical methods revealed the presence of two destabilizing feedback cycles responsible for these instabilities. Analysis of a spatially uniform system showed that the saddle-node bifurcation can be simulated within the reaction network. The introduction of diffusion results in two types of instabilities: one occurs when a spatially uniform system is already unstable, leading to a reaction–diffusion front; and another involves diffusion-driven instabilities where introducing diffusion destabilizes a stable spatially uniform system. Slower PdI2 diffusion plays a key role in inducing these instabilities. Equations describing conditions for the emergence of the instabilities in both cases were derived.
