It emerges from a nozzle that’s rarely wider than 400 microns in diameter, and can produce a continuous filament roughly the thickness of a human fingernail. 假设你想要打印一个半月板,半月板是膝盖里的一块软骨,用来避免胫骨和股骨互...
2.2. Strain and Long-Term Cultivation Conditions We used the unialgal, clonal Limnospira fusiformis strain ASW 01 100 (Algensammlung Wien, algae culture collection of the University of Vienna, Wien, Austria) with maintenance culture conditions provided, namely 25 °C and a day:night cycle of ...
of drug dosage and tablet spatial structure on the dissolution profiles. Given that the development of a method that allows the production of dosage forms with different properties from a single drug-loaded filament is desirable, we developed a method of printing ketoprofen tablets with different ...
All of the different light bulbs and electrical appliances offer a certain amount of resistance, also described as the load. This resistance is what makes the appliance work. A light bulb, for example, has a filament inside that is very resistant to flowing charge. The charge has to work ...
The heated filament is in a vacuum created inside a glass "tube." The "ray" is a stream of electrons that naturally pour off a heated cathode into the vacuum. Electrons are negative. The anode is positive, so it attracts the electrons pouring off the cathode. In a TV's cathode ray ...
An online UPS is a type of uninterruptible power supply that provides backup power to a computer or electronic device by supplying power from a battery or flywheel when the input power is lost. How long does a UPS last without power? Typically, a UPS will last for about 15 minutes without...
The heart of an X-ray machine is an electrode pair -- a cathode and an anode -- that sits inside a glass vacuum tube. The cathode is a heated filament, like you might find in an older fluorescent lamp. The machine passes current through the filament, heating it up. The heat sputter...
A transmission electron microscope fires a beam of electrons through a specimen to produce a magnified image of an object. A high-voltage electricity supply powers the cathode. The cathode is a heated filament, a bit like the electron gun in an old-fashioned cathode-ray tube (CRT) TV. It ...
If you let it build up long enough, the frost can get 6 inches thick and eventually there is no room to put anything in the freezer. This frost forms when water vapor hits the cold coils. The water vapor condenses -- turns to liquid water. Think of the water beading up on a glass...
Whether it's PP, PPFG, or OBC filament, LayerLock Build Surface for Polypropylene will provide the bed adhesion necessary to prevent warping. Achieving a strong bond between the first layer of your print and the heated bed's build surface is crucial for successfully avoiding warping. Like othe...
