While researchers have extensively studied the initial decomposition mechanism of Monomethylhydrazine (MMH, CH3NHNH2) in MMH/dinitrogen tetroxide (NTO) system, investigation Unsymmetrical Dimethylhydrazine (UDMH, (CH3)2NNH2) has been limited due to its high toxicity, corrosiveness, and deterioration rate. Hence, effects UDMH’s products on combustion performance gas-phase reaction mechanisms rem...

In this paper, the corrosion test of copper in hydrocracked base oil HC-6 was performed presence an additive for extremely high pressures (EP additive) different concentrations. EP additives are used to reduce wear industrial applications, under load conditions. Since most these sulfur-based, whose compounds can be corrosive at temperatures, their use leads some materials. To prevent with addit...

Abstract Hydrofluoric acid (HF) or fluoride ion corrosion issues are often encountered in many fields, which have attracted extensive research due to its strong corrosiveness. In this paper, a critical review is presented based on recent progress HF corrosion. view of the discrepancy compared with other ions, special attack characteristics firstly discussed. Afterwards, mechanisms stainless ste...

BACKGROUND Hydrofluoric acid (HF) is particularly dangerous due to the potential for systemic effects and induction of severe skin necrosis through two mechanisms: corrosiveness and local tissue toxicity. In addition, because it is only partially dissociated (pK(a) 3.2), it is capable of penetrating deeply into tissues. There is a lack of experimental studies that objectively characterize the b...

Carbon fiber reinforced polymer (CFRP) bars present advantages over conventional steel rebars such as non-corrosiveness and relatively high tensile strength. CFRP cannot directly substitute the main reinforcement for concrete structures due to a lack of understanding behavior CFRP-reinforced (RC) members. This research investigates effect surface characteristics deformed FRP on bond between con...

Stress Corrosion Cracking (SCC) is known as a trigger for material failure, especially in Dissimilar Metal Welding (DMW). Although DMW promises wide application structural design, it found that there high SCC mitigation making prone to failure. Capacitor Discharge (CDW) one of the best dissimilar metal welding methods. This article observes weld joints CDW ASTM A36 and SS 316L against phenomeno...

Vanadium Redox Flow Batteries (VRFBs) are promising candidates for large- scale energy storage applications however, there still some obstacles that need to be overcome such as their low density (25–30 Wh L−1 a 1.8 M electrolyte), high cost and large environmental impact due corrosiveness the unsustainability of vanadium. To address these challenges, we introduce lignin low-cost electrocatalyst...

Sulphur mustard (SM), chemically bis (2-chloroethyl) sulphide is a bifunctional alkylating agent that causes cutaneous blisters in human or animals. There is no specific therapy for SM induced skin injury, however, DRDE/WH-02 (containing PVP-I, Aloe vera gel and betaine) has proved to be an effective remedy for SM dermatotoxicity in preclinical studies. This study was planned to evaluate safety...
