This paper investigates a nano-enhanced wireless sensing framework for dissolved oxygen (DO). The system integrates a nanosensor that employs cerium oxide (ceria) nanoparticles to monitor the concentration of DO in aqueous media via optical fluorescence quenching. We propose a comprehensive sensing framework with the nanosensor equipped with a digital interface where the sensor output is digitized and dispatched wirelessly to a trustworthy data collection and analysis framework for consolidation and information extraction. The proposed system collects and processes the sensor readings to provide clear indications about the current or the anticipated dissolved oxygen levels in the aqueous media.

This essay aims to broaden the dialogue between physical activity (PA) and health by a salutogenesis-oriented concept, which emphasizes the origins of health, as opposed to the pathogenic model, which focuses on the origin of diseases. It presents the foundations of the theory, created by Aaron Antonovsky, whose health promotion model is centered on the sense of coherence (SOC), which consists of significance, comprehensibility, and manageability. Then, it explores the relationships between PA and salutogenesis, demonstrating how this framework can be applied in various life stages and practice settings.

Recently, metal-organic frameworks (MOFs) have shown high potential in the field of sensing. However, fluorescent-based detection with MOFs in solution needs complex pre-treatments and has stability issues, complicating measurements and handling for sensing applications. Here, an easy-to-handle and low-cost strategy is introduced to convert MOF-based sensing from solution to surface using scanning probe lithography.

Flexible metal-organic frameworks (MOFs) have emerged as a new generation of porous materials and are considered for various applications such as sensing, water or gas capture, and water purification. MIL-88 A (Fe) is one of the earliest and most researched flexible MOFs, but to date, there is a lack in the structural aspects that govern its dynamic behaviour. Here, we report the first crystal structure of DMF-solvated MIL-88 A and investigate the impact of real structure effects on the dynamic behaviour of MIL-88 A (Fe), particularly upon water adsorption.

Multisensory perception produces vast amounts of data requiring efficient processing. This paper focuses on the multisensory example of touch in biological and artificial systems. We integrate philosophical theories of multisensory perception with neuromorphic hardware and demonstrate how classical sensory integration concepts can enhance artificial sensory systems.
