Plasma technology used for textile and leather materials treatment is a dry, environmental friendly, and easy to operate method by which surface modification is obtained without altering the bulk properties of the materials. Particularly, nonthermal plasmas are very appropriate due to the fact that most textiles, and especially leathers, are usually heat sensitive. The major objective of this review is to provide a critical update on the present state‐of‐art relating to plasma and its effects on different textiles and leathers. We believe that the discussed subjects are helpful and may be used as an instruction guide for the future developments in the field of plasma‐activated textiles and leathers.

Microwave heating of high loss liquids was performed using two applicator types, a coaxial configuration and a pair of rectangular slot antennas. The temperature profiles in the asheated liquid samples were investigated in real time. The dielectric properties of the samples were measured over a broad band of frequencies at the same temperature value as the highest one reached in the temperature profile. The heating depth in the liquid was compared to the dielectric loss for different samples. These investigations were performed for surface microwave processing in liquid mixtures (living tissues), for extraction applications and medical thermal treatments.

Summer savory (Satureja hortensis L.) is most often used as a culinary herb, but it also has medicinal benefits. The extracts from control and irradiated savory were obtained by ultrasound extraction for 30 minutes in an ethanol — water (80:20, v/v) mixture. Polyphenolic compounds from savory were identified and characterized by high-performance liquid chromatography coupled with a photodiode array detector and mass spectrometer. The separation was performed using an Altima C18 column (100×3 mm, 3 μm) and as mobile phase two solvent mixture: A — acetonitrile and B — water-formic acid (99.9:0.1, v/v). Peaks were identified with authentic standards in accordance to retention time, UV spectra and molecular mass. It was identified as caffeic acid, rosmarinic acid, luteolin, naringenin and apigenin. A quantitative determination of polyphenolic compounds was performed applying the external standard method. Our study showed large quantitative differences between the control plant and the irradiated plant.
