The formation of single-phase solid solutions iron oxide and manganese with a spinel structure in MnxFe3 – xO4 system (x = 0; 0.3; 0.6; 0.8; 1.0; 1.2; 1.4; 1.8) has been established by methods X-ray phase analysis infrared spectroscopy. maximum saturation magnetization was found for the composition Mn0.3 Fe2.7O4 (Ms 68 A ⋅ m2 kg−1 at 300 K Ms 85 5 K), which is associated change cationic distrib...

Tomatoes are a crop of significant economic importance, and disease during growth poses substantial threat to yield quality. In this paper, we propose IBSA_Net, tomato leaf recognition network that employs transfer learning small sample data, while introducing the Shuffle Attention mechanism enhance feature representation. The model is optimized by employing IBMax module increase receptive fiel...

The negative effects of environmental estrogens on wildlife and human beings are gaining increasing attention. Research the highly sensitive detection method for Vitellogenin (Vtg), one biomarkers (EEs), is expected to detect weak in complex environments. This study aimed develop a label-free immunosensor with high specificity sensitivity testing Vtg. Carbon quantum dots (CQDs) fluorescence exc...

A voltammetric biosensor based on tyrosinase (TYR) was developed for determination of tyramine. Carbon material (multi-walled carbon nanotubes or mesoporous carbon CMK-3-type), polycationic polymer-i.e., poly(diallyldimethylammonium chloride) (PDDA), and Nafion were incorporated into titania dioxide sol (TiO2) to create an immobilization matrix. The features of the formed matrix were studied by...

Platinum pyrimidine "blues," a class of potent antitumor drugs [1] derived from cw-dichlorodiammineplatinum(II) (a's-PDD) or the corresponding hydrolysis product as-diaquodiammineplatinum(II) (cis-PDDa), have lately been the subject of considerable research effort in order to elucidate their structure and mode of action. The structure of platinum a-pyridone "blue," a Pt pyridine complex in some...

AgCl semiconductor nanocrystals (NCs) with trapezohedral (TPH) and concave hexoctahedral (HOH) structures have been successfully synthesized for the first time in high yield by a direct one-pot solvothermal method. The as-prepared TPH, concave HOH AgCl NCs with unconventional polyhedral shapes and smooth surfaces were enclosed by 24 high-index {311} facets and 48 high-index {15 5 2} facets, res...

We tested the hypothesis that the level of protein adsorption onto polyelectrolyte multilayers (PEMs) is influenced by the chain stiffness of the polymers forming the multilayer. The implication being that by altering the chain stiffness, PEMs can be formed that promote or inhibit protein adsorption. Protein adsorption to PEMs consisting of flexible and semi-flexible polyelectrolytes was invest...
