Instead, Stein suggests letting the carpet dry completely, then vacuuming the area thoroughly. “Sometimes, repeating the cleaning process a second time can make a difference, especially with ...
Dry carpet cleaning systems are more accurately known as "very low moisture" (VLM) systems, relying on dry compounds complemented by application cleaning solutions, and are growing significantly in market share due in part to their very rapid drying time, [4] a significant factor for 24-hour commercial installations.
A 98% biodegradable or other, [2] slightly moist absorbent cleaning compound may be spread evenly over carpet and brushed or scrubbed in. For small areas, a household hand brush can work such a compound into carpet pile; working like "tiny sponges", the attracted cleaning solution dissolves dirt, and dirt and grime is attracted/absorbed to the compound.
Vinyl floor tiling. Vinyl composition tile (VCT) is a finished flooring material used primarily in commercial and institutional applications. Modern vinyl floor tiles and sheet flooring and versions of those products sold since the early 1980s are composed of colored polyvinyl chloride (PVC) chips formed into solid sheets of varying thicknesses (1 ⁄ 8 in or 3.2 mm is most common) by heat and ...

The LVP instrument measures voltage waveform signals in the device diffusion regions. Device imaging is accomplished through the use of a laser scanning microscope (LSM). The LVP uses dual infrared (IR) lasers to perform both device imaging and waveform acquisition. One laser is used to acquire images or waveforms from the device, while the ...
Linear sweep voltammetry can identify unknown species and determine the concentration of solutions. E1/2 can be used to identify the unknown species while the height of the limiting current can determine the concentration. The sensitivity of current changes vs. voltage can be increased by increasing the scan rate.
Vanadium phosphates have been investigated as potential cathodes for Li-ion batteries: including lithium vanadium phosphate, Li 3 V 2 (PO 4) 3; [1] [2] the same material prepared by sol gel methods showed lithium insertion/removal over a 3.5 to 4.1 V range, with evidence of three stages of insertion/removal.
