Activation of carbon dioxide is the most important step in its conversion into valuable chemicals. Surfaces of stable oxide with a low work function may be promising for this purpose. Here we report that the surfaces of the inorganic electride [Ca24Al28O64](4+)(e(-))4 activate and split carbon dioxide at room temperature. This behaviour is attributed to a high concentration of localized electro...

BACKGROUND Carbon monoxide (CO) is known as a leading cause of unintentional poisoning death in many countries. Diagnosis is usually made by measuring carboxyhemoglobin (COHb), but due to the non-specific symptoms, the crucial step is considering CO poisoning. A possible solution might be screening emergency department (ED) patients. A cutaneous sensor that measures oxygen and CO saturation sim...

A cometary ice analog sample consisting primarily of carbon suboxide ice (C3O2) was produced from the irradiation of its precursor, carbon monoxide. This carbon suboxide sample was subjected to irradiation with energetic electrons at 10K to simulate the interaction of carbon suboxide-rich cometary analog ices with ionizing radiation. The destruction of carbon suboxide as well as the production ...

Rhabdomyolysis is most frequently caused by soft tissue injury with trauma to the extremities. Non-traumatic rhabdomyolysis may be caused by alcohol or drug abuse, infection, collagen disease, or intensive exercise, but incidence is low. In particular, rhabdomyolysis resulting from carbon monoxide poisoning is especially rare. If caught before death, carbon monoxide poisoning has been shown to ...

The effect of smoking five non-nicotine cigarettes and of breathing carbon monoxide on exercise-induced angina was evaluated in 12 patients with angina. Smoking increased venous carboxyhemoglobin from 1.71 to 5.35%, decreased exercise duration until angina 45%, increased ischemic STsegment depression at angina from 1.33 to 1.52 mm, and decreased systolic blood pressure times heart rate at angin...

INTRODUCTION Almost every known central neurological syndrome has been reported as a complication of carbon monoxide poisoning. Hemorrhagic infarct has rarely been considered as an early manifestation of carbon monoxide poisoning. A case of cerebral hemorrhagic infarction is presented. Typical findings, neuropathology and the role of vascular injury are described. CASE PRESENTATION The sympto...

The effects of carbon monoxide on exercise tolerance as assessed by the distance walked in 12 minutes were studied in 15 patients with severe chronic bronchitis and emphysema (mean forced expiratory volume in one second 0.56 1, mean forced vital capacity 1.54 1). Each subject walked breathing air and oxygen before and after exposure to sufficient carbon monoxide to raise their venous carboxyhae...

Poisoning by carbon monoxide from burning charcoal has become one of the popular and lethal ways of attempting suicide in Hong Kong. Survivors of the carbon monoxide poisoning often face acute and delayed adverse problems in both their physical and mental health. We report two cases of delayed onset neuropsychiatric complications caused by carbon monoxide poisoning from burning charcoal. These ...

The use of normobaric versus hyperbaric (>2 atm) oxygen in the treatment of carbon monoxide intoxication continues to be a matter of debate despite reports of increased efficacy with hyperbaric oxygen. When hyperbaric oxygen is used, immediate treatment is preferred for best results. The therapeutic window of time, however, is unknown. A patient presented with acute confusion and partial retrog...
