A method for characterizing particles suspended in a liquid, in a self-contained disposable cartridge for single-use analysis, such as for single-use analysis of a small quantity of whole blood. The method characterizes particles in liquid and samples a small and accurate volume of liquid. The ...
The initial dissolution peak of Cu suggests that Cu-rich particles on the surface start to detach and dissolve first23. The dissolution behavior of solutes in the peak-aged, under-aged, and over-aged alloys is similar, except that less dissolution of Mg and Zn is observed for the over-...
The fluid is a colloid, made of tiny particles suspended in a liquid. The particles repel each other slightly, so they float easily throughout the liquid without clumping together or settling to the bottom. But the energy of a sudden impact overwhelms the repulsive forces between the particles...
A non-Newtonian fluid is a type of liquid that doesn’t behave like most other liquids. Imagine if you were stirring a bowl of water; it would move around easily no matter how fast or slow you stirred it. But if you were to stir a non-Newtonian fluid, like slime or ketchup, it ...
Although this doesn’t - as some report - change the viscosity of the fluid, the realignment of the particles is capable of giving it an almost solid state, making it harder for the damper’s piston to move through. The strength of the field determines how ‘solid’ the fluid is, allowi...
Particles surf their own waves, reveal how microbes and cells move through human body A ball falling through goopy liquid will generate a wave in a nearby flexible rubber sheet. The ball will 'surf' the wave, moving away from the rubber sheet and picking up speed, new calculations and ...
If you drop paint from high up, you make it move faster. It might also impact the water more, making the process more difficult. Take a sequence of shots as the paint makes beautiful clouds. After each iteration, we need to clean and refill the tank. Try using two colors to make the...
While air particles are extremely small, they do have mass, and so they are pulled toward the Earth. At any particular level of the Earth's atmosphere, this pull is very slight — the air particles seem to move in straight lines, without noticeably falling toward the ground. So, pressure...
The worst thing to do is to thrash around in the sand and move your arms and legs through the mixture. You will only succeed in forcing yourself farther down into the liquid sandpit. The best thing to do is to make slow movements and bring yourself to the surface, then just lie back....
Physical exfoliantsact like your body scrub. It contains abrasive particles that help lift off the debris. Physical exfoliation requires a bit of effort from your side: you need to gently massage your scalp for a couple of minutes to achieve the desired result. ...
