Oxygen enriched PAni-based counter electrode network toward efficient dye-sensitized solar cells (DSSCs).

Dye-sensitized solar cells (DSSCs) have great potential as a renewable energy technology assisting combat climate change due to its low cost, adaptability, and sustainability. Oxygen plasma ion doping is a promising strategy to improve the capacity of a low-cost, platinum-free counter-electrodes (CEs) to absorb photons and drive high-performance DSSCs via generating an abundance of active absorption sites. In this instance, novel PAni-ZnO (PZ) composite layers were designed as a CE material and received various in-situ oxygen plasma dosages, including 0, 2, 4, 6, 8, and 10 min, to improve their physiochemical and microstructural feature for the first time, to the best of our knowledge.

Pressure distribution analysis of X-Ray table mattresses.

Background: There is a risk of developing pressure ulcers from lying on an X-ray table mattress, if the mattress pressure redistribution properties are poor.

Aim: To assess the pressure redistribution properties of 'new' and 'in current clinical use' X-ray table mattresses.

Methods And Materials: Twenty one X-ray table mattresses, each of 2.

A Phantom-Based Method to Assess X-Ray Table Mattress Interface Pressures.

Background: Pressure redistribution performance of x-ray table mattresses can influence the development of pressure ulcers in at-risk populations. Interface pressure analysis, with human participants, is a common method to assess mattresses. This approach has limitations that relate to the lack of standardisation between and within humans.
