and out of cells by simple diffusion. Diffusion movement of molecules from a region of high concentration in the region of low concentration by random molecular motion (www.biologyplace.com). Diffusion in the solution can be accelerated by...
passive UHF RFID systems (Raghunathan: 457 – 462) . Thus an on-board energy supply is necessary, which forces a renaming of the previously called passive UHF RFID technology to semi-passive and active technology. This change in the tag arch...
the total amount of membrane in a cell. Most animal cells, especially those that have specialized functions, are so packed with membranes that there may be 50 to 100 times as much membrane inside them as on their surface. (In plant cells t...
cells are shaped or created by biological membranes, the obstacles that characterise the interior and the out-of-doors of a cell. (De Weer 2000, 919-926) These obstacles avert substances developed interior the cell from leaking out and redu...
polymer electrolyte membrane fuel cells (PEMFC), direct methanol fuel cells (DMFC), solid oxide fuel cells (SOFC), molten carbonate fuel cells (MCFC) and alkaline fuel cells (AFC). Each has its own electrolyte, cathode and anode as well as ...
