Amphiphilic Nanoscale Antifog Coatings: Improved Chemical Robustness by Continuous Assembly of Polymers.

Designing effective antifog coatings poses challenges in resisting physical and chemical damage, with persistent susceptibility to decomposition in aggressive environments. As their robustness is dictated by physicochemical structural features, precise control through unique fabrication strategies is crucial. To address this challenge, a novel method for crafting nanoscale antifog films with simultaneous directional growth and cross-linking is presented, utilizing solid-state continuous assembly of polymers via ring-opening metathesis polymerization (ssCAP).

Reduced Ice Adhesion Using Amphiphilic Poly(Ionic Liquid)-Based Surfaces.

Ice build-up on solid surfaces causes significant economic losses for a range of industries. One solution to this problem is the development of coatings with low ice adhesion strength. Amphiphilic poly(ionic liquid) (PIL)-based surfaces have been recently reported for antifogging/antifrosting applications.

Mechanochromophore-Linked Polymeric Materials with Visible Color Changes.

Mechanical force as a type of stimuli for smart materials has obtained much attention in the past decade. Color-changing materials in response to mechanical stimuli have shown great potential in the applications such as sensors and displays. Mechanochromophore-linked polymeric materials, which are a growing sub-class of these materials, are discussed in detail in this review.

Crosslinked Polypeptide Films via RAFT-Mediated Continuous Assembly of Polymers.

Polypeptide coatings are a cornerstone in the field of surface modification due to their widespread biological potential. As their properties are dictated by their structural features, subsequent control thereof using unique fabrication strategies is important. Herein, we report a facile method of precisely creating densely crosslinked polypeptide films with unusually high random coil content through continuous assembly polymerization via reversible addition-fragmentation chain transfer (CAP-RAFT).

Spontaneous cervical haematoma caused by extracapsular haemorrhage from a parathyroid carcinoma presenting with acute onset neck swelling and dysphonia.

We present the case of a 69-year-old male patient who presented with progressive neck swelling causing symptoms of dysphonia and dysphagia. Flexible nasendoscopy revealed bruising of the right hemilarynx, hypopharynx and parapharyngeal mucosal consistent with a spontaneous cervical haematoma. After conservative management, the haematoma self-resolved and the source of the haematoma was thought to be a parathyroid adenoma.
