Organic photovoltaic (OPV) cells are at the forefront of sustainable energy generation due to their lightness, flexibility, and low production costs. These characteristics make OPVs a promising solution for achieving sustainable development goals. However, predicting their lifetime remains challenging task due to complex interactions between internal factors such as material degradation, interface stability, and morphological changes, and external factors like environmental conditions, mechanical stress, and encapsulation quality.

This study explores the synergistic antibacterial effects of essential oils (EOs) and phenolic extracts from three plants against foodborne pathogenic bacteria. The present work aimed to investigate the synergistic effects of the binary and the ternary combinations of extracts using different blend proportions of the following plant extracts: (AC), (AHA), and (CA). The antimicrobial activities of EOs and phenolic extracts were determined and evaluated against five strains.

This study investigated the seasonal variation (over seven months) of phenolic acid (PHA) components in different parts of Centaurea sp. The primary objective was to determine the pattern of variation, while the secondary objective was to identify which month or growth stage provides a greater total PHA content or percentage of bioactive components. Different patterns of seasonal variations were highlighted for the different PHA components and their classes (hydroxybenzoic and -cinnamic acids) in different parts of the plant.

in folk medicine is used by Algerian traditional healers for treating a wide variety of diseases and conditions including dyspepsia, digestive problems, peptic ulcers, and, in particular, inflammatory diseases. The present study aimed to assess the phytochemical composition, in vitro antioxidant activity (using 2,2-diphenyl-1-picrylhydrazyl (DPPH), ABTS+, and reducing power methods), enzyme inhibitory activity (towards α-amylase and urease), antibacterial activity, and in vivo anti-inflammatory activity of the unripe fruit extracts of collected from different parts of the Djelfa region of Algeria. According to the findings, various aqueous extracts exhibited significant antioxidant and enzymatic activities in all tests, but showed that they have a weak inhibitory effect against all tested bacterial strains.

Statistical Approach and Neutron Activation Analysis for Determining Essential and Toxic Elements in Two Kinds of Algerian Artemisia Plant.

Biol Trace Elem Res

June 2021

Technical Platform of Physico-Chemical Analysis (PTAPC-Laghouat), P.O. Box. 37G, Road of Ghardaïa, 03000, Laghouat, Algeria.

Article Synopsis
  • The study analyzed two types of Artemisia plants from Djelfa province, Algeria, using instrumental neutron activation analysis (INAA) to identify essential and toxic elements for the first time.
  • The analysis found a total of twenty-one elements in the plants, with significant concentrations of potassium (K), calcium (Ca), iron (Fe), and sodium (Na).
  • The results suggest that the daily intake of these plants falls within safe limits set by the World Health Organization (WHO), providing a scientific basis for their medicinal use and enhancing the knowledge of herbal remedies.
