Organic Sensitizers for Indoor DSSC Applications
Among the emerging photovoltaic (PV) technologies, Dye-Sensitized Solar Cells (DSSCs) appear especially interesting in view of their potential for unconventional PV applications. In particular, DSSCs have been proven to provide excellent performances under indoor illumination, opening the way to their use in the field of low-power devices, such as wearable electronics and wireless sensor networks, including those relevant for application to the rapidly growing Internet of Things technology. Considering the low intensity of indoor light sources, efficient light capture constitutes a pivotal factor in optimizing cell efficiency. Consequently, the development of novel dyes exhibiting intense absorption within the visible range and light-harvesting properties well-matched with the emission spectra of the various light sources becomes indispensable.

Cholinesterase Methods forNerve Agents Detection Using Optical Evaluation
The extreme toxicity of nerve agents and the broad spectrum of their physical and chemical properties, enabling the use of these agents in a variety of tactical situations, is a continuing challenge in maintaining the knowledge and capability to detect them, as well as in finding new effective methods. With the military standardization of V-series agents (VX), the sensitivity of traditional chemical methods was no longer satisfactory; therefore, increased attention was paid to cholinesterase methods. The reduction of enzyme activity after contact with NAs allows for the detection of these cholinesterase inhibitors with high sensitivity since, in this case, one and the same enzyme acts as both a sensitive element and an amplifier of the analytical signal.
