In article number 2009553, Hyomin Lee, Chang-Hyung Choi, and co-workers present hydrogel microcapsules with an intermediate thin oil layer that enable the smart release of a broad range hydrophilic cargoes triggered via diverse stimuli. The osmotic pressure overall stiffness can be fine-tuned to control onset time behavior multi-cargo encapsulated either simultaneous or selective.

A novel Building Integrated Concentrating Photovoltaic (BICPV) Smart Window has been designed and developed as a next generation intelligent window system. In response to climatic conditions, the smart window varies solar light transmission into the building for provision of light and heat with the reflection of light to the photovoltaic (PV) for electricity generation. This unique function is ...

Abstract The unique properties of smart hydrogels combined with conducting surfaces opened new possibilities in the construction novel electrochemical devices. Electrodes modified thin gel layers demonstrate that are usually unachievable for bare electrodes. Usually a layer provides highly permeable matrix analytes, and can also serve as an immobilizing/impermeable larger molecules. Hydrogel ba...

Hydrogel, a material with outstanding biocompatibility and shape deformation ability, has recently become hot topic for researchers studying innovative functional materials due to the growth of new biomedicine. Due their stimulus responsiveness external environments, hydrogels have progressively evolved into “smart” responsive (such as pH, light, electricity, magnetism, temperature, humidity) i...

Flexible triboelectric nanogenerators (TENGs) with multifunctional sensing capabilities offer an elegant solution to address the growing energy supply challenges for wearable smart electronics. Herein, a highly stretchable and durable electrode TENG is developed using ZIF-8 as reinforcing nanofiller in hydrogel LiCl electrolyte. nanocrystals improve hydrogel's mechanical properties by forming h...

A new way is demonstrated to develop a bio-inspired coacervate hydrogel by following catechol chemistry showing injectable and re-moldable physical properties. The formed coacervate shows potential long-term stability under water. Depending on pH, formation of the coacervate has been verified which is confirmed by XPS and zeta potential measurements.

conclusions this study showed that compared to standard drug treatment, treatment with hydrogel containing peptide had substantial antibacterial effects on s. aureus wound infections in mice. results the highest and lowest numbers of wounds were observed on day 2 in the negative and positive control groups, respectively. during the 8-day period, the positive control and hydrogel containing pept...

cell-based biosensors have become a research hotspot in biosensors and bioelectronics fields. the main feature of cell-based biosensors is the immobilization of living cell on the surface of transducers. different types of polymers which are used as scaffolds for cell growth should be biocompatible and have reactive functional groups for further attachment of biomolecules. in this work, the cel...

Polyacrylic acid/ octavinyl polyhedral oligomeric silsesquioxane, nanocomposite hydrogel with 3-D network was synthesized via radical polymerization. Octavinyl polyhedral oligomeric silsesquioxane was used as crosslinker and nanofiller simultaneously in the preparation of the hydrogel. Hydrogel adsorption performance was determined by adsorption of methylene blue. The adsorption capacity was ev...
