Methanol is sometimes referred to as ethanol's deadly twin. While the latter is the intoxicating ingredient in wine, beer and schnapps, the former is a chemical that becomes highly toxic when metabolised by the human body. Even a relatively small amount of methanol can cause blindness or even...
by analyzing its headspace and distinguished it from pure liquor. As first proof-of-concept, the detector was also tested on breath of an intoxicated volunteer, where it could clearly identify the sample spiked with toxic methanol concentrations. Thus, it shows promise for quick and non-invasive...
By using a large amount of data, our machine-learning algorithm was able to classify the 4D vectors for different gases with high consistency when they are tested individually. The gas-sensing patterns in binary mixture conditions of water and methanol vapors were qualitatively distinguished. The ...
Parameters: RP-18 column; water phase contained 5% methanol, 0.2% acetic acid and water; organic phase was 100% methanol. Flow rate at 20 μl/min; detection wavelength at 254 nm; Peak ABC as the data analysis software. Rutin standard was purchased from Sigma. After calculation, the result...
Electrochemical energy conversion devices, such as fuel cells, can convert the chemical energy of different fuels into electricity, with minimal to no emissions [3,4]. Direct alcohol fuel cells, fed by liquid fuels such as ethanol and methanol, are promising alternatives to hydrogen-fed fuel ...
A further increase in the share of ethanol allowed for this indicator to be reduced down to the level of 1–1.5% (with the permissible limit of 1.5%). Dual-fuel direct injection systems currently involve a number of combinations, among which are the injection of methanol and diesel fuel [...
Liver sections (25 mg) were extracted at the mixed organic solvent (acetonitrile: methanol: water = 2: 2: 1), and vibrated on a vortex oscillator for 1 min. After centrifugation at 10,000g for 15 min at 4 °C, the supernatant was taken into a centrifuge tube and evaporated to dryness...
The function of PtOHads in electrochemical oxidations of small organic molecules (such as CO27, methanol28,29, and ethanol30–33) and other compounds (such as thiosulfate and thiourea34) has been studied in previous reports. However, the function and mechanism of Pt oxides at higher potentials...
small as 4.75 ± 0.77 nm (the inset in Fig.1dand Supplementary Fig.3). The size of PdZn NPs being small can be also reflected by the XRD detection which shows no PdZn signals except for neat ZnO peaks (Supplementary Fig.4). After the ZnO being etched away, there are ...
tests were performed to determine their stability and long-term durability. The synthesized AgPt (1:3)/C electrocatalyst presented significative catalytic activity and superior durability due to the introduction of Ag that weakens the chemisorption of the carbonaceous species. Thus, it could be an at...
