A damp-proof course (DPC) [2] is a barrier through the structure designed to prevent moisture rising by capillary action such as through a phenomenon known as rising damp. Rising damp is the effect of water rising from the ground into property. [3] The damp proof course may be horizontal or vertical. [4]
In construction, a building or structure is waterproofed with the use of membranes and coatings to protect contents and structural integrity. The waterproofing of the building envelope in construction specifications is listed under 07 - Thermal and Moisture Protection within MasterFormat 2004, by the Construction Specifications Institute, and includes roofing and waterproofing materials.
In fluid statics, capillary pressure is the pressure between two immiscible fluids in a thin tube (see capillary action), resulting from the interactions of forces between the fluids and solid walls of the tube. Capillary pressure can serve as both an opposing or driving force for fluid transport and is a significant property for research and ...
Incipient wetness impregnation (IW or IWI), also called capillary impregnation or dry impregnation, is a commonly used technique for the synthesis of heterogeneous catalysts. Typically, the active metal precursor is dissolved in an aqueous or organic solution. Then the metal-containing solution is added to a catalyst support containing the same ...

In earlier days, birch bark was occasionally used as a flashing material. [7] Most flashing materials today are metal, plastic, rubber, or impregnated paper. [8]Metal flashing materials include lead, aluminium, copper, [1] stainless steel, zinc alloy, other architectural metals or a metal with a coating such as galvanized steel, lead-coated copper, anodized aluminium, terne-coated copper ...
This has been suggested to be due to absorption of photons by the increasing density of solvent molecules., [20] [21] However, this leads to the benefit that APPI can extend to very low flow rates (e.g., 1 μL/min domain) allowing for effective use with capillary LC and capillary-electrophoresis. [22]
A promising application area for biochips is clinical pathology, especially the point-of-care diagnosis of diseases. [72] In addition, microfluidics-based devices, capable of continuous sampling and real-time testing of air/water samples for biochemical toxins and other dangerous pathogens , [ 73 ] can serve as an always-on "bio-smoke alarm ...
