Aeroxide® TiO2 P90 (Evonik‚ Germany) was used in all experiments as the photocatalyst. The properties of TiO2 nanoparticles are given in Table 3.1 according to the supplier. The suspensions were prepared by dispersion of the desired amount of TiO2 in deionized water. The suspension was magnetically mixed at the stirrer speed of 500 – 600 rpm. Table 3.1. Characteristic physicochemical data of Aeroxide® TiO2 P90 Properties Unit Primary particle size µm 14 Specific surface area (BET) m2/g 90 ± 20

- Molecules move from hypertonic to hypotonic‚ until it reaches an isotonic state (or equilibrium). At that point‚ molecules will move equally across the membrane. 10-1 Cell Growth surface-area-to-volume-ratio: the ratio of surface area to volume cell division: division of a cell (also called mitosis) Explain why larger organisms are made of many small cells rather than one large cell‚ emphasizing the

Renal failure can be caused by many different factors. Something that would cause a failure would be impaired blood flow to the kidney. Ways this could happen could be: blood or fluid loss blood pressure medications‚ heart attack‚ heart disease‚ infection‚ liver failure‚ use of aspirin‚ ibuprofen (Advil‚ Motrin IB‚ others)‚ naproxen (Aleve‚ others) or related drugs‚ severe allergic reaction (anaphylaxis)‚ severe burns‚ or severe dehydration. Another way renal failure could occur is if there is direct

ACTIVITY 1: THE RESTING MEMBRANE POTENTIAL 1. Explain why increasing extracellular K+ reduces the net diffusion of K+ out the neuron through the K+ leak channels? When the diffusion is greater on one side‚ the other side will slow down. 2. Explain why increasing extracellular K+ causes the membrane potential to change to a less negative value. How well did the results compare with your predictions? There are two potassium’s for every sodium so the increase of potassium will make it more

total testosterone may be warranted in the clinical decision-making of this patient. Free testosterone has been estimated from the serum for some time by dialyzing serum across a semipermeable membrane with the testosterone that crosses in the serum believed to be the unbound portion or free. Most dialysis assays use small tracer amounts of radiolabeled testosterone added to the serum.

Shadish‚ Rob Harris‚ Patricia Tellekamp Water appears to cross the differentially permeable membrane of potato cells by a process called osmosis. The measure of the energy involved in osmosis is called water potential. Since water must lose energy as it moves by osmosis‚ water must move from an area of greater potential to an area of less water potential‚ until the water potential on either side of the membrane is the same‚ at which point the cell has reached equilibrium. The two major parameters influencing

Eddy Current 1. The principles of eddy current testing depend on the process of electromagnetic induction. 2. This process includes a test coil through which vary or alternating current (AC) is passed. 3. A varying current flowing in a test coil produces a varying electromagnetic field around the coil‚ As shown in this diagram Amperage * # of coils= strength of magnetic field 4. The electromagnetic field produced around the coils is directly proportional
