10-pack of spay nozzles able to make a thin-film liquid sheet. The spray nozzles are manufactured from borosilicate glass. The nozzles are able to create free-flowing, sub-micron, liquid sheets which are two orders of magnitude thinner than anything previously reported. Optical, infrared, and X-ray spectroscopies are used to characterize the sheets, which are found to be tunable in thickness from over 1 μm down to less than 20 nm, which corresponds to fewer than 100 water molecules thick. At this thickness, aqueous sheets can readily transmit photons across the spectrum, leading to potentially transformative applications in infrared, Xray, electron spectroscopies and beyond. Their use is demonstrated at free-electron laser and synchrotron light sources.

Have a look at our clogging prevention guide
Is your setup clogged with dirt or fully blocked?
Chips can get clogged, for example when they’ve been used before and have not been cleaned the right way. If your chip is clogged with dirt, check our document on the prevention of clogging and/or read the answer to question number one on this page (regarding the cleaning of chips). Clogged chips often do let some flow through the chip, which makes it easier to identify the issue as clogging. If there is no flow at all it’s more likely that the flow path is not connected correctly.
Pinpoint the issue
We recommend walking through the full track of the fluid flows: check if your syringe or pump is not blocked, if your tubing is actually hollow and if your filters let fluids pass through. Then check if your chip has inlet and outlet holes and if these are positioned so that the fluids can go through the chip. The easiest way to do this is to disassemble the setup and check if fluids come out of the pump, then connect the tubing and check if fluids can come through. Keep on adding parts and checking if the fluids go through. This way you can pinpoint the problem.
If the problem remains
If the problem cannot be solved after following the above-mentioned steps, then take some pictures or make a short movie of your setup and send this, together with the description or name of your chip, to Micronit. We will gladly assist you in identifying the issue.
