Summary: Conductive polyzwitterionic hydrogels with good adhesion properties are promising for implantable electrodes and electronic devices. By introducing tannic acid, the hydrogels' adhesive properties in humid environments can be enhanced without compromising their toughness. The addition of TA coated nanoflowers and nanofibers as reinforcing phase provides a noncovalent cross-linking mechanism, resulting in a highly stretchable hydrogel with excellent anti-biofouling property and resistance to bacteria and cells. The hydrogel also possesses a low modulus and high ionic conductivity, making it an ideal material for implantable electrodes.

Summary: Hydrogels show promise in agriculture as water reservoirs in dry soil, but their ability to swell can be reduced when confined in soil due to competition between osmotic swelling force and confining force. The medium can also be restructured by hydrogel swelling, depending on the balance of forces involved. These findings offer quantitative principles to predict hydrogel behavior in confinement, potentially improving their agricultural use and informing other applications.

Summary: Frequency Interferometric Localization Microscopy (FILM) is a novel super-resolution microscopy technique that incorporates a Michelson interferometer into a wide-field fluorescence microscope to obtain spectral information of individual fluorophores using coherence time as an auxiliary axis. By isolating the homogeneous linewidth of individual fluorophores from the inhomogeneous broadening distribution, nearby fluorophores with distinguishable central wavelengths can be accurately localized beyond the diffraction limit in the frequency domain. With properly prepared fluorophores, FILM has the potential to achieve molecular-scale spatial resolution in principle.

Summary: This paper presents a new vertical inertial sensor with interferometric readout, which achieves high sensitivity and is expected to be limited by thermal noise below 10 Hz. Compared to commercial L-4C geophones, the potential sensitivity improvement is about two orders of magnitude at 10 mHz and 100 mHz, and one order of magnitude at 1 Hz. Performance limitations such as tilt-to-vertical coupling and nonlinearity in the interferometric readout are also discussed.

Summary: Carbon capture and storage (CCS) is an essential measure to achieve CO2 emission reduction goals. Shut down oil and gas fields in the North Sea are potential sites for large-scale offshore CO2 storage due to their proven storage capacity, reliable caprock integrity, infrastructure, and acceptance. However, some legacy wells may compromise CO2 containment due to uncertainties in their integrity. Reliable and cost-effective technologies are needed for well integrity evaluation and remediation. This paper discusses a workflow for screening, monitoring, and remediation of legacy wells.

Summary: Photopolymerization technology is limited in the fields of food packaging and biomedicine due to the high migration of small molecules from photoinitiators. In this study, a polymerizable 2-vinyl thioxanthone (ETX) was synthesized to improve the migration stability of photoinitiators. Macromolecular photoinitiators (PPI1, PPI2) were also prepared to further reduce migration. The results showed that the ETX/TEOA system had higher initiation performance and PPI2 displayed favorable initiation ability. Additionally, the migration of ETX, PPI1, and PPI2 in photocured film was significantly reduced. These low-migration photoinitiators have potential applications in the fields of food packaging and biological materials.

Summary: This study investigates the effect of plasma treatment on carbon nanotubes (CNTs) and the structure/properties of polyimide (PI) nanocomposites with ultra-low content of CNTs. The results show that plasma treatment introduces isocyanate groups on the surface of CNTs and enhances the interfacial interaction between PI and treated CNTs. This leads to a significant improvement in the mechanical properties of the nanocomposites, with even a small addition of treated CNTs showing a substantial increase in Young's modulus, tensile strength and toughness.
