Sir,—Digestion of the sweetener aspartame yields aspartic acid and phenylalanine, plus methanol. has questioned aspartame's safety, alleging (1) that methanol is a "cumulative poison", (2) that a toxicity syndrome is producible "only in humans", (3) that "formaldehyde is a known carcinogen", (4) that ethanol protects against methanol in food sources, (5) that the.

Two structural forms of a ternary alloy PtRuIr/C catalyst, one amorphous and one highly crystalline, were synthesized and compared to determine the effect of their respective structures on their activity and stability as anodic catalysts in methanol oxidation. Characterization techniques included TEM, XRD, and EDX. Electrochemical analysis using a glassy carbon disk electrode for cyclic voltamm...

CO poisoning during methanol electrooxidation was investigated on PtAu alloys with different surface compositions. Results show that the CO formation can be reduced gradually with increasing surface Au fractions in PtAu alloys and CO poisoning can be almost eliminated by adjusting to a proper surface Au fraction.

The anode electro-oxidation of methanol is central to the operation of Direct Methanol Fuel Cells (DMFC), which have the potential to become the fastest growing next generation mobile power sources. While Pt and Pt-based catalysts are known for their effectiveness in methanol activation, they are also most susceptible to catalyst poisoning by reaction intermediates such as CO. A second or even ...

Methanol intoxication produces a well recognized clinical picture characterized by gastrointestinal, ocular and nervous system symptoms. The effect of poisoning on the cardiovascular system has not been well documented. We report the case of a 55 year old man whose acute methanol intoxication caused severe reversible cardiac failure. This represents the first description of an association betwe...

Methods: Retrospective medical record review of 122 patients in a cluster outbreak of methanol poisoning. Data collected included history, complete ocular and systemic examination details, time to presentation, amount of alcohol ingested, and results of laboratory investigations, such as hemogram, glucose levels, hematocrit level, arterial pH, methanol levels, potassium and bicarbonate levels, ...
