Abstract:
Formulations of road over-stabilized cationic bitumen emulsions with orthophosphoric, sulfuric and hydrochloric acids and cationic emulsifiers for slowly disintegrating emulsions have been designed. The physical and mechanical properties of the manufactured over-stabilized bitumen emulsions and their breaking behavior were determined. It has been established that over-stabilised bitumen emulsions demonstrate good storage stability for 180 days. The obtained results of breaking behavior bitumen emulsions indicate that emulsions based on hydrochloric and sulfuric acid have a shorter fines mixing

It was found that cement formed using pyrophosphoric acid solution set more slowly than that formed using orthophosphoric acid and could be mixed to a higher powder to liquid ratio, facilitating the production of cement exhibiting compressive strengths, without pre-compaction, as high as 25 MPa.

Introduction: Orthodontics, a dental specialty focused on correcting dental anomalies and malocclusions, frequently relies on materials such as orthophosphoric acid (H₃PO₄) for enamel etching during bracket bonding procedures. However, this acid may induce changes in salivary pH, potentially altering the oral microbiota and increasing the prevalence of mucosal lesions. Methods: A clinical and epidemiological study was conducted on 30 patients aged between 10 and 25 years, all undergoing fixed multibracket orthodontic therapy.

Abstract:
This thesis describes the effects of phosphoric acid on the positive lead dioxide electrode of a lead-acid cell. The aim of this research was to evolve a mechanism for the action of phosphoric acid on the charge (PbSO4→PbO2) and discharge (PbO2→PbSO4) processes. Industrially, phosphoric acid is added to the battery electrolyte because it has certain beneficial effects of preventing formation of 'hard' sulphate and reduction in shedding of active material resulting in improved cycle life. The main disadvantage of phosphoric acid-containing electrolyte is a reduction in capacity of the cell.

Abstract Corrosion in process industries often occurs in mixtures of various acids and salts. Such corrosion behavior cannot be predicted simply by extrapolation from the behavior in pure acids. For example, corrosion behavior in wet process phosphoric acid is significantly different from that in pure orthophosphoric acid due to a variety of impurities in the former. Corrosion behavior in sulfuric and hydrofluoric acid mixtures is quite different from that in either of the pure acids. Acid mixtures can be broadly classified as: (1) mixtures of two non-oxidizing strong acids; (2) mixtures with
