Article Abstract
Anti-icing and de-icing are vital for infrastructure maintenance. While carbon-based materials with photothermal or electrothermal effects have advanced, they face challenges like environmental dependence, poor resistance, high energy consumption, and complex manufacturing. Here, we developed a scalable, hybrid metamaterial driven by photothermal/electrothermal for all-weather anti-icing/de-icing. Its nanostructured surface delays icing by 360 s at -30°C, breaking records across a wide temperature range. The porous structure enhances light absorption, achieving a delayed icing time of 2500 s at -20°C under one sunlight. The graphene film's high conductivity allows rapid de-icing with 1.6W power. After 720 h of outdoor exposure, the metamaterial retained a contact angle above 150°, confirming durability. More critically, we have demonstrated that the metamaterial can be manufactured on a large scale, which is essential for improving the economics of the anti-icing/de-icing sector.

The expansion of single-cell analytical techniques has empowered the exploration of diverse biological questions at the individual cells. Droplet-based single-cell RNA sequencing (scRNA-seq) methods have been particularly widely used due to their high-throughput capabilities and small reaction volumes. While commercial systems have contributed to the widespread adoption of droplet-based scRNA-seq, their relatively high cost limits the ability to profile large numbers of cells and samples.

The Internet of Things (IoT) and Industrial Internet of Things (IIoT) have drastically transformed industries by enhancing efficiency and flexibility but have also introduced substantial cybersecurity risks. The rise of zero-day attacks, which exploit unknown vulnerabilities, poses significant threats to these interconnected systems. Traditional signature-based intrusion detection systems (IDSs) are insufficient for detecting such attacks due to their reliance on pre-defined attack signatures.

Polyvinylidene fluoride (PVDF)-based materials are the most researched polymers in the field of energy harvesting. Their production in thin-film form through printing technologies can potentially offer several manufacturing and performance advantages, such as low-cost, low-temperature processing, use of flexible substrates, custom design, low thermal inertia and surface-scaling performance. However, solution-based processes, like printing, miss fine control of the microstructure during film-forming, making it difficult to achieve a high level of polarization, necessary for PVDF to exhibit electroactive characteristics.

We have executed a cost-effective approach to produce a high-performance multifunctional human-machine interface (HMI) humidity sensor. The designed sensors were ecofriendly, flexible, and highly sensitive to variability in relative humidity (%RH) in the surroundings. In this study, we have introduced a humidity sensor by using carbon paper (as both a substrate and sensing material) and a silver (Ag) conductive ink pen.
