Turkish Journal of Chemistry
The sensitizer is one of the most essential dye-sensitized solar cell (DSSC) components. In the present research, a Zn-astaxanthin complex was investigated as a sensitizer, compared to pure astaxanthin. The complex with a 1:1 mole ratio between astaxanthin and Zn2+ was synthesized in a reflux reactor at 37–60 °C. The product was analyzed using Proton Nuclear Resonance (1H-NMR), which indicates the presence of chelate formation between Zn2+ with two atoms of oxygen on the terminal cyclohexane ring of astaxanthin. The interaction of sensitizers (astaxanthin and Zn-astaxanthin) on the photoelectrode surface in this study was analyzed using a Fourier Transform Infra-Red …

Improving The Water Solubility Of Cannabidiol Using A Peptide Carrier, Melek Parlak Khalily
Turkish Journal of Chemistry
Cannabidiol (CBD), nonpsychotropic cannabinoid found in Cannabis sativa, is a very promising drug candidate offering many differential effects such as sedative, antiinflammatory, antioxidant, and neuroprotective properties. Nevertheless, the therapeutic use of CBD is hindered by its lack of water solubility and relatively low bioavailability. Various carriers have been used to address the solubility issues of CBD and other highly lipophilic drugs so far. However, self-assembled peptide nanostructures as carrier have not been used to improve the water solubility of CBD yet. In this study, a self-assembling peptide micelle was demonstrated to be an effective vehicle for encapsulation of CBD and …

In recent years, there has been an increasing interest in producing new materials that use renewable resources and halogen-free flame retardants with nonleaching properties. This research focuses on designing and synthesizing phosphorus-nitrogen-based biopolyols for use in polyurethane (PU) foam production. Polyol (ESBO-DYM) with dual functionalities, renewability, and nonflammability is synthesized through the epoxy ring-opening reaction of epoxidized soybean oil with phosphorus and nitrogen-containing tetraol products (DYM). The mechanical and flame retardant properties of PU foams with the addition of an ESBO-DYM were investigated. Increasing the amount of phosphorus in the PU foams increased the thermal stability properties. Using 100% ESBO-DYM …

Soil is the main influencing factor for plant growth, reproduction, and distribution. With the acceleration of industrialization and the intensification of human activities, the problem of heavy metal pollution in agricultural soil is becoming increasingly prominent. Heavy metals in soil are toxic and easily absorbed by plants, and consuming contaminated crops poses a great threat to human health. Therefore, it is necessary to monitor the content of heavy metals (HMs for short here) in soil. Hyperspectral Remote Sensing (HRS for short here) has great application prospects in obtaining quantitative information of soil organic matter, minerals and other components due to …

As an important macro element for all living cells, phosphorus is essential in agricultural production systems as well and is required in large quantities by elite varieties of crops to maintain yields. Approximately 70% of worldwide cultivated land suffers from phosphorous deficiency, and it has recently been estimated that worldwide phosphorous resources will be shattered by the end of this century thus increasing the demand for crops to be more efficient in their P usage. A greater understanding of how plants can maintain yield with lower phosphorous availability is highly desirable to both breeders and farmers, therefore, significant to develop …
