The amplitude of the mouse ERG declines with age. This change does not appear to reflect a change in the structural integrity of the photoreceptor cells. In functional studies of murine models of late-onset retinal disorders, it will be important to take these changes into consideration.

Flexible wearable sensors are expected to be the future generation of personal health monitoring devices with large‐area, multimodal, multipoint sensing, and complicated data analysis. However, multimaterial interfacial coalescence and mechanical matching critically challenge the advancement of flexible devices and multifunction integration. Graphene, with characteristic carbon sheet 2D material, is endowed with good transparency, stability, superior electron mobility, heat conductivity, excellent flexibility, and mechanical performance. A summary of the progresses of flexible graphene‐based sensors in terms of material processing, sensor configuration, and property is presented. Various assembly structures could perform different electrical behaviors with unitary graphene material. The diversity of graphene‐based temperature, humidity, pressure, strain, and integrated multifunctional sensors developed in recent years is detailed. Benefitting from the commendable flexible mechanical performance and high durability, flexible graphene‐based sensors promote practical applications in body temperature monitoring, voice recognition, pulse‐beating, motion, and respiration detection. Finally, future research following the development trends and challenges of integrated graphene‐based sensors to develop their potential in human health monitoring and human–machine interfaces are discussed.

Supercharged unfolded polypeptides (SUPs) are exploited for controlling ice nucleation via tuning the nature of charge and charge density of SUPs. The results show that positively charged SUPs facilitate ice nucleation, while negatively charged ones suppress it. Moreover, the charge density of the SUP backbone is another parameter to control it.

The fabrication of micro-and nanostructures in polymers has attracted considerable attention. Here, a general method defined as secondary phase separation (SPS) is developed, which regulates the growth of polymers into multiple dimensions including one-dimensional (fiber-like), two-dimensional (flower-like), or three-dimensional (3D; sphere-like) structures. A theoretical understanding of the growth evolution in the polymer multidimensional structures is clearly proposed based on classical nucleation theory and Oswalt ripening. In particular, the multidimensional superstructures of poly(lactic acid) (PLA) exhibit strong water repellency (e.g., contact angle > 150°, sliding angle < 10°, and adhesive force < 5 μN). The resultant PLA foam composed of microspheres exhibits good shape recovery after compression due to its 3D alternating rigid (PLA microspheres) and soft (air space) skeleton. This skeleton can be further implemented for the selective absorption of organic pollutants (like chlorobenzene), showing a high yield of up to 21 g g −1 without any mass loss after 10 cycles. This work provides a new strategy to prepare polymer foams with multidimensional micro/nanostructures and shows potential in selective absorption and water purification.

Solar energy-facilitated icephobic films have emerged as clean and renewable materials, which can potentially solve energy loss problems during anti-icing/deicing applications. However, there is a significant challenge for all-day and continuous anti-icing/deicing applications under practical conditions with insufficient sunlight or no sunlight. In this work, a chemical oxidation polymerization method was used to prepare in situ self-wrinkling porous poly­(dimethylsiloxane) (PDMS)/polypyrrole (PPy) (POP-P) films based on a facile sugar template method. The porous-structured film enhanced light absorption by elongating the optical path for multiple reflections, maintaining an outstanding broad-band solar light absorption (295–2500 nm) and an exceptional photo-thermal effect. The light-to-heat performance showed a temperature enhancement from room temperature to 89.1 °C within 400 s under 1 sun illumination (q i = 1.0 kW m–2). In addition, this membrane also exhibited an electro-thermal effect at different voltages due to the Joule effect, and the saturation temperature could reach 75.4 °C at a voltage of 32 V. As an anti-icing/deicing material, this POP-P surface remained ice-free (−25 °C) throughout alternating of day and night, under conditions of a solar intensity of 0.8 kW m–2 and a voltage of 25 V.

The solution-processing fabrication of superhydrophobic surfaces is currently intriguing, owing to high-efficiency, low cost, and energy-consuming. Here, a facile nonsolvent-assisted process was proposed for the fabrication of the multi-scaled surface roughness in polylactide (PLA) films, thereby resulting in a significant transformation in the surface wettability from intrinsic hydrophilicity to superhydrophobicity. Moreover, it was found that the surface topographical structure of PLA films can be manipulated by varying the compositions of the PLA solutions. And the samples showed superhydrophobic surfaces as well as high melting enthalpy and crystallinity. In particular, a high contact angle of 155.8° together with a high adhesive force of 184 μN was yielded with the assistance of a multi-nonsolvent system, which contributed to the co-existence of micro-/nano-scale hierarchical structures.
