Plants have
tiny pores on their leaves called stomata — Greek for mouths — through which they take in carbon dioxide from the air and from which water evaporates.
The next step was to soak the plants in that solution and pressurize them, which causes the particles to enter the leaves through
tiny pores called stomata.
The belief in the ability of trees, shrubs and bushes to remove pollutants from the air, by trapping them on their leaves, absorbing them
through tiny pores called stomata on the leaf surface, or via the roots, is by no means misplaced.
The final product, a black carbon powder, has a very high surface area due to the presence of
many tiny pores that have been chemically etched on the surface of the microspheres.
The networked polymer is made from joining smaller molecules
with tiny pores, and selectivity is programmed into the material through a crosslinked monomer.
When rainwater is introduced to this kind of rock, either seeping in through
tiny pores in the rock surface, or, more typically, dribbling in through larger cracks, the rock will begin to dissolve.
«These types of natural gas and oil are in tiny,
tiny pores that range from a few millionths of a meter in diameter to a few thousandths of a meter,» Lee said.
Bamboo charcoal - as moso bamboo plants mature (taking 5 years),
tiny pores are created that absorb allow it to act as a deodorizer.
The carbon is then treated with chemicals to etch in
the tiny pores.
The polymer covering contains holes that are larger than graphene's pores, which Hart says act as microscopic «drumheads,» keeping the graphene sturdy and
its tiny pores open.

tiny pores, which was in agreement with the structure (grayscale image) observed in a scanning electron microscope.
«It's moving through
the tiny pores between the sand grains and it gets smeared, like grease on a tie.»
Zeolite crystals are a popular industrial «sieve» because
their tiny pore spaces allow only certain molecules to slip through.
But some of it also enters the stomata, or
tiny pores, on the leaves and is drawn down through the branches to the roots.
Researchers have demonstrated for the first time that they can continuously read the chemical letters of DNA as it travels through
a tiny pore, paving the way for a new kind of sequencing machine that decodes DNA much like an announcer reading a ticker tape.

a tiny pore in the cell membrane using an ultra-short laser pulse from a femtosecond laser.
The reason goes back to
the tiny pores, called stomata, which exist on leaves and needles and are the channels through which trees absorb CO2 and cool off through evaporation.
According to a report in this week's issue of Current Biology,
tiny pores in the outer membranes of two species of bacteria secrete a stream of slime that propels them forward.
«
These tiny pores mean scientists could potentially «sift» molecules into different sizes to study them individually.
Tiny pores in the charcoal, along with changes in its chemistry, provide more surfaces for nutrients to adhere to, which in turn encourages microorganisms to colonize the soil.
