Photoisomerization of chromophores usually shows significantly less efficiency in solid polymers than solution as strong intermolecular interactions lock their conformation. Herein, we establish the impact macromolecular architecture on isomerization main-chain-incorporated (i.e., α-bisimine) both and state. We demonstrate that branched architectures deliver highest for main-chain chromophore state─remarkably high 70% compared to solution. The design principles established herein efficient...
Caniformia include a range of aquatic, semi-aquatic and terrestrial species, which reveal diversity in their whisker arrangements shape. Whisker movements play crucial role the perception tactile information, allowing whiskered mammals to distinguish between shapes, sizes, textures. Despite significance sensory perception, few studies have focussed on measuring during sensing. enrichment tasks potential expand behavioural repertoires animals captivity reduce stereotypical behaviours....
We explore a cross-linked polymer network based on visible light photodynamic [2 + 2] cycloaddition driven by styrylpyrene chemistry. Based backbone with pendent units, the can be formed using λ = 450 nm irradiation. Upon irradiation 340 nm, photostationary state is generated within ∼17% of units open compared to close 2% in cured state. The limited fraction couples caused their proximity and sharp contrast solution experiments photoreactive moiety. Thus, retains its mechanical properties...
Resolving the anonymity of plastic materials is critical for safeguarding well-being our natural environments and human health.
An alternative synthetic route towards the widely employed electroactive poly(TEMPO methacrylate) (PTMA) via a thermally robust methoxyamine-protecting group is demonstrated herein. Protection of radical moiety hydroxy-TEMPO with methyl functionality and subsequent esterification methacrylic anhydride allows high-yielding formation novel monomer methyl-TEMPO methacrylate (MTMA). The polymerization MTMA to poly(MTMA) (PMTMA) investigated free reversible addition-fragmentation chain-transfer...
We find that the topology of phase diagrams for block copolymer/ionic liquid (IL) blends and scaling phase-separated domains are significantly influenced by cation structure IL. have varied bis(trifluoromethane sulfonyl)imide ILs investigated influence these changes on thermodynamics with polystyrene-b-poly(methyl methacrylate). Effective χ parameters (χeff) were determined used to plot diagrams, where significant differences observed, suggesting balance Coulombic van der Waals interactions...
The feasibility of passive sampling biological matrices to quantify contaminants has been demonstrated using polydimethylsiloxane (PDMS). PDMS has, however, low sorptive capacity for hydrophobic compounds (with Klipid–PDMS ∼ 30–40), and increasing the sampler volume thus extent chemical mass transfer is not feasible because concomitant lipid transfer. We therefore developed new polymers by graft polymerization from substrates evaluated mechanism kinetics Klipid–polymer was significantly...
We demonstrate the light-induced, crosslinker mediated collapse of linear polymer chains into single-chain nanoparticles (SCNPs) capable self-reporting their unfolding.
An increasing body of research is being conducted on the development wave energy converters as a potential source renewable energy. To directly convert low-speed oscillation into electrical energy, several bespoke machines have been developed by researchers, often only demonstrated in dry laboratory environment. prove reliable operation at sea, generic converter this paper which ideally suited for demonstrating an integrated small scale direct drive generator ocean. This gives design details...
Spatially controlling self-assembly of block copolymer thin films through photoinduced molecular interactions that significantly impact on the glass transition temperature.
This paper compares two variable reluctance permanent magnet machines – a flux reversal and vernier hybrid variant. The machine, which is being developed in conjunction with Mocean Energy, required to operate at very low speed. describes the application electrical topology development, focus on optimization routine used. Results show there conflict between peak torque cogging torque, but also that induced voltage are highly dependent sensitive rotor tooth width, rather than if machine or type.
The power take off for wave energy remains one of the key technical challenges that must be overcome before maturity. low speed reciprocating nature many devices combined with challenging environment require development bespoke electrical machines in a direct drive system. This paper describes research project is developing small device. aim to prove can reliably operate marine environment.
