Physisorption, also
called physical adsorption, is a
process in
which the
electronic structure of the atom or
molecule is
barely perturbed upon adsorption...
-
reactants are the adsorbate. Two
types of
adsorption are recognized:
physisorption,
weakly bound adsorption, and chemisorption,
strongly bound adsorption...

creates new
types of
electronic bonds. In
contrast with
chemisorption is
physisorption,
which leaves the
chemical species of the
adsorbate and
surface intact...

species involved, but the
adsorption process is
generally classified as
physisorption (characteristic of weak van der
Waals forces) or
chemisorption (characteristic...
-
practically no
physisorption, and
hence no deposition. The
closer the
deposition temperature is to the
threshold temperature the
weaker the
physisorption. Parylene...
- The
observations are very
often referred to as
physical adsorption or
physisorption. In 1938,
Stephen Brunauer, Paul Hugh Emmett, and
Edward Teller presented...

Adsorption may
occur via
physisorption and chemisorption. Ions and
molecules can
adsorb to many
types of surfaces...
- can be
broadly classified as
being one of two types:
physisorption or chemisorption.
Physisorption is
characterized by weak van der

Hydrogen physisorption can be
increased in
these materials by

physisorption resulting in a net

Inert and
lighter gases, such as He and H2 tend not to
sputter and are
absorbed by
physisorption. Some...
