Tenders are invited for Instrument For Physisorption
And Temperature Program Experiments
A part of these ions belongs to nonelectrosorption, namely, the physisorption
or chemisorption; the other part belongs to electroadsorption, which is reversible.
On the other hand, the values for the mean adsorption energies (E) that were obtained for the systems that were studied according to the DubininRadushkevich equation were found to be lower than the interval 1-16 kJ/mol for a physisorption
of nitrogen was carried out at liquid nitrogen temperature.
Two devices for determining the surface area, size distribution and a micropore volume and mesopore by physisorption
gas enabling measurement of at least three samples simultaneously.
Enthalpy values less than 40 KJ mol-1 are associated with physisorption
(electrostatic attraction), rather than chemical bonding .
Limited Tenders are invited for Supply And Installation Of Multi-Purpose Adsorption Measurement With Physisorption
And Chemisorption Capabilities
The adsorption of [H.sub.2], [H.sub.2]O, [O.sub.2], CO, C[O.sub.2], NO, N[O.sub.2], N[H.sub.3], and C[H.sub.3]OH on C-CNT, B-CNT, and Si-CNT are calculated and can be characterized as physisorption
and chemisorption, as indicated by the magnitude of adsorption energy ([E.sub.ad]) and binding distance (BD).
Tenders are invited for Equipment For Physisorption
The surface areas of catalysts were calculated by using the Brunauer-Emmett-Teller (BET) method, with Micromeritics ASSP 2020 equipment by [N.sub.2] physisorption
at 77 K.
This instrument(s) should have the capability to facilitate automated physisorption
measurements relevant to research in the areas of porous materials including metal organic frameworks, activated carbon, carbon nanotubes and zeolites.
