Article Synopsis
- The study discusses a new method for creating ultraporous titanium dioxide thin films using plasma deposition and etching, which can be done at room or mild temperatures.
- These films have over 85% porosity, maintain their structure even after high-temperature annealing, and exhibit unique properties like being antireflective and superhydrophilic under UV light.
- The resulting porous films can be used as electrodes in perovskite solar cells and have potential applications in various fields such as energy storage, photonics, and controlled wetting due to their scalable and solvent-free synthesis process.
This study explores the impact of plasma treatment on Lavandin Grosso flowers and its influence on the extraction of essential oils (EOs) via hydrodistillation. Short plasma treatment times enhance the yield of EO extraction from 3.19% in untreated samples to 3.

Evidence also exists about a positive effect of plasmas for germination under environmental stress conditions. For barley seeds, this work studies the influence of cold plasma treatments on the germination rate and initial stages of plant growth in common stress environments, such as drought, salinity, and low-temperature conditions.

In this investigation, the texture and surface roughness of porous titanium samples obtained by the space holder technique were modified with a femtosecond Yb-doped fiber laser. Different percentages of porosity (30, 40, 50, and 60 vol.
