Summary: The study investigates the assembly of nanoparticles at the air/water interface using Langmuir films. By inducing conformational changes within a PNIPAM capping layer, the assembly of nanoparticles with a diameter of 90 nm can be controlled. The system shows reversible switching between uniform and nonuniform states, with the densely packed and uniform state observed at higher temperatures. The findings provide guidelines for designing adaptive 2D systems, such as programable membranes or optical interfacial devices.

Summary: This paper reviews the formation, structure determination, and properties of polyelectrolyte multilayer (PEM) films and capsules that respond to physical, chemical, and biological stimuli. It discusses their applications as microcarriers for controlled release, substrates for controlled cell growth, coatings for enhanced surface adhesion, and self-healing anticorrosive systems. The impacts of various stimuli on the integrity and permeability of the films or capsules shell are presented, along with their applications in controlled drug release, biotechnology, and industrial protective coatings.

Summary: The study presents the synthesis and characterization of a novel triple stimuli responsive interpenetrating polymer network (IPN) based on two polyzwitterionic networks. The IPN hydrogel can expand or shrink in response to changes in temperature, pH, and salt concentration. It has good mechanical stability and exhibits non-cytotoxicity and antibiofouling activity against various bacteria. The in vivo behavior suggests that this smart material has great potential as a biomaterial.

Summary: A model based on the coupled diffusion-deformation mechanism was developed to predict the large deformation caused during the reversible folding behavior of polymeric thin films accurately. The concentration dependent Young's modulus variation was found to be essential in accurately predicting folding curvatures. The model successfully predicted buckling and wrinkling phenomenon observed in stimuli-responsive polymer thin films.

Summary: Cu(0)-mediated atom transfer radical polymerization was used to synthesize a poly(ionic liquid), a stimuli-responsive polyelectrolyte, and a novel block copolymer formed from these two polymers. The control of livingness polymerization was evaluated through the synthesis of the block copolymer. Various characterization techniques were employed to study the supramolecular interactions and morphology of the block copolymer. The results demonstrated the potential of the PDMAEMA-b-PVBBImTf(2)N block copolymer in polymer-inorganic nanoparticle composite applications.

Summary: In this work, a method for synthesizing temperature and light-responsive copolymers by introducing azobenzene fragments in the side chain of poly(2-oxazoline)s is proposed. The obtained copolymers exhibited thermo-responsive behavior and reversible isomerization of azobenzene units under UV and visible light exposure. The presence of nanoparticles in the aqueous solutions of the copolymers was confirmed, and the size of these nanoparticles changed in response to UV irradiation.

Summary: A telechelic rhodamine-bearing poly(2-isopropyl-2-oxazoline) (Rh-PiPrOx-Rh) was synthesized by living cationic ring-opening polymerization and end-group functionalization using amine-functionalized rhodamine 6G. Rh-PiPrOx-Rh demonstrated hydrophilic-hydrophobic phase transition behavior at a lower critical solution temperature. The rhodamine moieties exhibited pH-responsive and Al3+-sensitive absorption and emission changes. Under physiological conditions, amphiphilic Rh-PiPrOx-Rh formed polymeric micelles that could be dissociated by binding with Al3+. The thermo-responsive properties of Rh-PiPrOx-Rh were also significantly altered by the addition of Al3+.

Summary: This study introduces a biobased photonics film with multi-stimuli responsive behavior to humidity, solvent, and pH stimuli, showing dramatic color changes and high sensitivity. The film displayed fast response and good reversibility under different ethanol concentrations, as well as significant color changes in response to pH variations in the range of 2 to 12, with no interference between humidity, solvent, and pH responsiveness.

Summary: Sclerolinum annulatus n. sp. is a newly described species of Siboglinidae found in the Haima cold seep of the South China Sea. It is morphologically distinct with transverse rings and elongated plaques on both sides of the dorsal furrow. Genetic analysis supports its placement in the genus Sclerolinum with a close relationship to an undescribed siboglinid from Japan.

Summary: We used ancient DNA extraction methods to confirm the genetic identity of a polychaete species that has been a matter of debate since its description. Our results revealed a high genetic match with a cryptic seep species. Additionally, we found that chemosynthesis-based polychaetes in Arctic seeps are not seep specialists and may have a relatively generalist habitat. Our findings suggest that Arctic chemosymbiotic animals seasonally vary their reliance on chemosynthetic partners due to the extreme seasonality of the Arctic.
