Using sound waves to levitate individual droplets of solutions containing pharmaceutical drugs and drying them in mid-air. Why do this? This is useful because most of the drugs on the market are either amorphous or crystalline and the crystalline form doesn’t get absorbed by the body. So levitating the solution allows the drug to be made into an amorphous state (by evaporation) because if it were to touch any surface it would simply crystallize. They call this “containerless processing”.
The frequencies used are just above the audible range at about 22 kilohertz and when the two speakers are aligned they create two sets of sound waves, perfectly interfering with each other creating a phenomenon known as a standing wave. This allows the objects to levitate in areas within the waves known as nodes as the acoustic pressure is enough to cancel the force of gravity.
And now I made a PWxDW crossover! Phoenix always gets the most bizarre character as his clients.
Why should women be paid equal to men? Men have been in the working world a lot longer and deserve to be paid at a higher rate. Heck, I’m a working mom and I’m not paid a dime. I depend on my husband to provide for me and my family, as should most women… and if a woman does work, she should be happy just to be out there in the working world and quit complaining that she’s not making as much as her male counterparts. I mean really, all this wanting to be equal nonsense is going to be detrimental to the future of women everywhere. Who’s going to want to hire a woman, or for that matter, even marry a woman who thinks she is the same, if not better than a man at any job. It’s almost laughable. C’mon now ladies, are you with me on this?
