A porous barrier is a barrier against the movement of one type of objects that is not a barrier to the movement of another type of objects. A "real life" example would be a picket fence, which stops motion of objects, such a s adult humans, that are larger than the distance between the pickets but not those of smaller objects such as snakes and insects. However, the most common use of the phrase is in engineering and physical chemistry, specifically in osmosis and reverse osmosis technology, battery design, and other electrochemistry. In these fields, porous barriers have been devised that permit the flow of water but not electrolytes, of cations but not anions, etc.
What else can I help you with?
Is metal porous?
Metal is not porous. Many other elements are porous though and when metal combines with them it can potentially become porous.
What does non-porous mean?
Porous means 'with holes'. So non-porous means 'without holes'
Definition of porous and non porous materials?
Porous means, containing pores ie, small or tiny hole, while non-porous means, without pores or holes.
How many types of barriers of communication are there?
There are many types of barriers of communication for example; language barrier, physical barrier, emotional barrier, listening barrier, cultural barrier, gender barrier etc
Why must an eggshell be porous?
for oxidation
What is it called when you use a porous barrier to separate solids?
Filtration.
Can filtration to separate solids from liquids by using a porous barrier?
Yes, that's what filtration is.
What cells form a porous membrane surrounding the endothelial cells of the glomerulus?
Podocytes form a porous membrane known as the glomerular filtration barrier surrounding the endothelial cells of the glomerulus. These specialized cells have foot-like extensions that interdigitate to create filtration slits, contributing to the selective permeability of the barrier.
Which technique uses a porous barrier to separate a solid from a liquid?
Filtration is a technique that uses a porous barrier, typically a filter paper or sieve, to separate a solid from a liquid. The liquid passes through the barrier while the solid particles are retained on the filter.
What is a type of barrier that lets in all things?
A type of barrier that lets in all things is known as a "permeable barrier." This type of barrier allows the passage of various substances, including liquids, gases, and even small particles, without restriction. An example of this is a mesh screen or a porous material, which can facilitate the movement of air and water while blocking larger objects.
What happens on sound waves when it hits a barrier?
When waves pass through a narrow gap, be they light or sound, they diffract. This creates an interference pattern of some sort, often depending on the wavelength of the sound and the size of the gap.
Is a concrete non porous?
There are two types porous and non porous. You can also seel porous concrete to make it non porous.
Is concrete non porous?
There are two types porous and non porous. You can also seel porous concrete to make it non porous.
What has the author A F Brown written?
A. F. Brown has written: 'Partial separation of the uranium isotopes by diffusion through a porous barrier' 'A flow meter for small gas flows'
Is silk porous or nonporous?
Silk is porous -- it absorbs liquids.
Is polystyrene a good sound insulator?
Polystyrene is neither sufficiently porous nor of sufficient mass to be either a good Sound Absorber, or a Sound Barrier. [Those are the proper technical terms.]
Is metal porous?
Metal is not porous. Many other elements are porous though and when metal combines with them it can potentially become porous.
