The structure of the glass forming system (V2O5)x – (Na2O · P2O5)(1–x), (x = 0–0.4), has been investigated using Raman spectroscopy. The stretching vibrations of various phosphate groups, connected to phosphorus or vanadium atoms, have been assigned. Variation of the composition leads to structural changes where the sodium metaphosphate -P–O–P-chains break and then reconnect with the oxovanadiu...

p2o5-sio2 (30% w/w) was found to be a useful catalyst for the synthesis of various 2-substituted aryl benzimidazoles under solvent-less and in solvent conditions from o-phenylenediamine and aldehydes. the products were directly recrystallized from methanol.

In this paper, we report the study of the loading and the release of curcuminoids by bioactive glasses (BG) and mesoporous bioactive glasses (MBG). Through a detailed spectroscopic study, it was possible to determine the amount and the type of molecules released in water and in simulated body fluid (SBF). In particular, curcumin and K2T21 show a good ability to be released in di-keto and keto-e...

This Bulletin discusses several manufacturing processes for organic compound fertilizers overseas and in Taiwan. The different formulations of N-P2O5-K2O in the fertilizers are also reported. The yield response of different crops from the application of organic compound fertilizer reflects their superiority over organic fertilizers. Experiments also showed that the use of organic compound ferti...

Long-term research shows that phosphorus (P) and nitrogen (N) fertilizer must be applied to optimize production of irrigated corn in western Kansas. In 2020, N alone increased yields by 85 bu/a, whereas P 10 bu/a. Nitrogen together up 136 bu/a which is 11 less than the 10-year average 147 The application 120 lb N/a (with highest rate) produced 98% maximum yield greater (2011–2020). 80 instead 4...

Abstract The objective of the present study was to determine best phosphite source and concentration control anthracnose its effects on physical chemical characteristics ‘Prata-anã’ banana. Bouquets banana fruits were immersed in solutions containing different formulations copper FCu1 (4% Cu + 20% P2O5), FCu2 22% P2O5) at concentrations 0.5; 1.0, 1.5- 2.0-mL L-1 potassium FK (42% P2O5 27.7% K2O...
