The plastic hardener methyl ethyl ketone peroxide is unstable peroxide that releases free oxygen radicals. Ingestion of this compound induces widespread liver necrosis, severe metabolic acidosis, corrosive esophagitis and gastritis, that is often fatal. A 49-year-old man unintentionally ingested approximately 100 mL (55%) of this compound in solution, which was purchased as plastic hardener. De...

Methyl Ethyl Ketone Peroxide (MEKP) is a highly toxic clear liquid used as a solvent. It is a strong oxidizing agent and a corrosive. Acute and chronic toxicity can occur as an occupational hazard. Ingestion is associated with corrosive burns leading to stricture formation, inhalational pneumonitis, acidosis, liver failure and renal failure. In this paper we present a case of a young patient wh...

UNLABELLED Seven esophageal reconstructions with interposition colon in severe suicide corrosive ingestion and Boehave's injury at Thammasat University Hospital were presented. Vascular enhancement (as called "supercharge") were done. Only one patient had micro-leakage at pharyngeal anastomosis with healed by conservative treatment and no late anastomotic stricture. The operation need more time...

In this study microorganisms from Antarctic soils were isolated using different selective nutrient media. The soils were collected from different habitats of Livingston Island. The microorganisms were isolated and purified to pure culture. The isolated microorganisms were micro-morphologically and macromorphologically characterized. The results obtained suggested that despite the extreme Antarc...

Waters from natural sources of the São Miguel Island in the Azores archipelago have been investigated regarding their corrosive action on metallic materials. The corrosive and encrusting characteristics of the waters have been established in terms of relevant chemical parameters (namely pH, conductivity, total dissolved solids (TDS), and concentrations of bicarbonate, calcium, magnesium, chlori...

Ten cases of combined corrosive and peptic strictures of the oesophagus have been described. The peptic stricture of the oesophagus occurred 20 to 50 years after the corrosive burn. The authors believe that the hiatal hernia was due to the contraction of the fibrotic wall of the oesophagus, and therefore they prefer to call it a traction hiatal hernia. The operation of choice in these cases is ...

Abstract For components serving in high temperature, humidity, and salinity marine corrosive environment, it is vital to analyze the causes of corrosion behavior mechanisms. Metal matrix composites (MMCs) are commonly used materials for offshore equipment. In this work, factors MMCs environments analyzed from characteristics service mechanisms summarized. Graphene (Gr) has excellent comprehensi...

The corrosion process involves a sequence of reactions in which a metal or an alloy is attacked by an aggressive agent [4, 13]. Due to their particular electronic structure characterized by the presence of free electrons in the crystalline network, metals and alloys react chemically or electrochemically and thus may suffer corrosion processes [13, p.85]. The stabile chemical state of the metals...

Sustainable synthesis schemes for the production of porous carbons with appropriate textural properties for use as supercapacitor electrodes are in high demand. In this work a greener option to the widely used but corrosive KOH is proposed for the production of highly porous carbons. Hydrochar products are used as carbon precursors. It is demonstrated that a mild alkaline potassium salt such as...
