charged ion collision48,49under laboratory conditions. Most of what is known about H3+chemistry comes from reactive scattering experiments and from ion-neutral reactions in flow drift tubes. These measurements, full collisions, provide reaction cross sections and in some cases angle-resolved product st...
The time scales and formation mechanisms of tri-hydrogen cation products in organic molecule ionization processes are poorly understood, despite their cardinal role in the chemistry of the interstellar medium and in other chemical systems. Using an ultrafast extreme-ultraviolet pump and time-resolved nea...
Please visit Domain of Experts for other recommended Chemistry tutors. I will be busy for the next couple of months moving house (from Tampines to Bedok). I will be able to accept students some time in the 1st quarter of 2025. Students can email me now at bedokfunland@yahoo.com to regis...
摘要: Abstract A collision chamber designed for efficient collection of product ions was used to determine the extent of back scattering in the reactions of D+ and H2 to form H+ and HD+. No significant amount of back scattering in the laboratory system was detected....
the H2SO4 will form, but that almost always will break down to make CO2 and H2O that's why i threw in a disclaimer by using the word approximately before i said 100% Logged AP Chemistry Squad Member [V]rctrackstar2007 Full Member Posts: 265 Mole Snacks: +18/-40 Gender: I ...
Table 1 Operating conditions of experiments performed in the FVC Full size table The H2-air Ф = 0.56 mixture has a low Lewis number of 0.39, for which the flame can undergo thermodiffusive instabilities (Berger et al. 2022). However, under the H2-air Ф = 0.56 condition, the ...
To further improve the activity, cubic MoC was introduced into Mo2C to form the carbon-modified MoC-Mo2C nanoparticles (MoC-Mo2C@C) by a calcination method. The resultant MoC-Mo2C@C (ca. 5 nm) was eventually coupled with TiO2 to acquire high-efficiency TiO2/MoC-Mo2C@C by electrostatic ...
The MOF-in-COF membrane displayed a H2 permeance as high as 1.3 × 10−6 mol m−2 s−1 Pa−1 and the H2/CH4 separation factor was 33.3. The MOF-in-COF membrane is regarded as the most promising membrane material for hydrogen separation. Download: Download full...

Additional contrast is presented in the bimetallic supercrystal, indicating platinum activation. Full size image First, wavelength-dependent catalytic experiments were performed on the bimetallic supercrystal, which made it possible to discriminate the photocatalyst response in different spectral regions48. ...
