| 单词 | semipermeable membrane |
| 例句 | At the heart of every fuel cell lies a semipermeable membrane. Generating clean electricity with chicken feathers 2023-10-20T04:00:00Z Figure 20.31 The semipermeable membrane of a cell has different concentrations of ions inside and out. College Physics for AP Courses 2015-08-12T00:00:00Z Diffusion-driven transfer of solvent molecules through a semipermeable membrane is a process known as osmosis. Chemistry 2019-02-14T00:00:00Z The blood is separated from a solution, called the dialysate, that is designed to remove wastes by diffusion through a semipermeable membrane. Biology for AP Courses 2022-06-09T00:00:00Z This creates a pressure, osmotic pressure, which will exist until the solute concentration is the same on both sides of a semipermeable membrane. Anatomy and Physiology 2013-06-19T00:00:00Z By pumping the positive ions—like sodium or potassium—to the other side of a semipermeable membrane, researchers can create two pools of water: one with a positive charge, and one with a negative charge. Rivers could generate thousands of nuclear power plants worth of energy, thanks to a new ‘blue’ membrane 2019-12-04T05:00:00Z Osmosis is the transport of water through a semipermeable membrane from a region of high concentration to a region of low concentration. College Physics for AP Courses 2015-08-12T00:00:00Z This is the pressure that must be applied to the solution to prevent diffusion of molecules of pure solvent through a semipermeable membrane into the solution. Chemistry 2019-02-14T00:00:00Z The blood is separated from a solution, called the dialysate, that is designed to remove wastes by diffusion through a semipermeable membrane. Biology for AP Courses 2022-06-09T00:00:00Z Figure 3.7 Osmosis Osmosis is the diffusion of water through a semipermeable membrane down its concentration gradient. Anatomy and Physiology 2013-06-19T00:00:00Z There was no lightbulb-over-my-head moment; just the constant drip-drip percolation of facts and feelings through the semipermeable membrane of my mind. The Choice: Two Red-Eyes, 36 Sleepless Hours and Still a Choice 2011-05-12T16:47:47Z Figure 19.32 The semipermeable membrane of a cell has different concentrations of ions inside and out. College Physics for AP Courses 2015-08-12T00:00:00Z Osmosis is the transport of water through a semipermeable membrane from a region of high concentration to a region of low concentration. College Physics for AP Courses 2015-08-12T00:00:00Z Fructose diffused because of the pore specificity of the semipermeable membrane, not because of its concentration gradient. Biology for AP Courses 2022-06-09T00:00:00Z Whenever a substance exists in greater concentration on one side of a semipermeable membrane, such as the cell membranes, any substance that can move down its concentration gradient across the membrane will do so. Anatomy and Physiology 2013-06-19T00:00:00Z Similarly, dialysis is the transport of any other molecule through a semipermeable membrane due to its concentration difference. College Physics for AP Courses 2015-08-12T00:00:00Z One type of semipermeable membrane has small pores that allow only small molecules to pass through. College Physics for AP Courses 2015-08-12T00:00:00Z For example, if pure water and sea water are separated by a semipermeable membrane that passes no salt, osmotic pressure will be 25.9 atm. College Physics for AP Courses 2015-08-12T00:00:00Z Dialysis is the transport of any other molecule through a semipermeable membrane due to its concentration difference.
