Shape deformations of hydrogels are achieved by changing the surface areas isotropic with simple, facile and efficient scratching photolithography patterning methods.
A UV light emitting diode (LED) with a maximum output of 372 nm was collimated using a pinhole and a small plastic tube and focused using a microscope objective onto a substrate for direct lithographic patterning of the photoresist. Movement of the substrate with a motorised linear stage (syringe pump) allowed lines in SU-8 to be pattered with a width down to 35 microm at a linear velocity of 8...
Photolithography is when light is used to put an image from a photo mask onto a wafer that has photo resist on it thus creating integrated circuits or other technology such as read/write heads for hard drives. Reservoir Switching Units can fail to detect resist on the Photolithography tool or the Millipore pump thus introducing air into the resist lines and ultimately causing scrap due to poor ...
Background and purpose: Despite extensive studies on prevention and management of deep vein thrombosis (DVT), less attention has been paid to chronic venous insufficiency. The persend study aimed to investegite the incidence and clinical signs of post thrombotic syndrome in patients with deep vein thrombosis. Materials and methods: A descriptive retrospective study was done in patients with DV...
Abstract As one of the most advanced and precise equipment in world, a photolithography scanner is able to fabricate nanometer‐scale devices on chip. To realize such small dimension, optical system fundamental, but mechanical often becomes bottleneck. In photolithography, exposure dynamic process. The accuracy precision movement are determined by system, which even more difficult control compar...
