This paper proposes a novel technology to fabricate 3D curved structures on SU-8 resist by a photo-acid-diffusion process. This technology deliberately modifies the standard SU-8 photolithography procedure and allows the diffusion of photo-acid released from UV-exposed regions into the adjacent unexposed resist regions, which would result in forming smooth 3D curved structures after cross-linking...
The combustion and spray process of DI diesel was calculated using CFD software - FIRE. Some important research information, including the distribution of the velocity of flow field, temperature field and cylinder pressure as well as heat release rate, were got and analyzed detailedly as a predictable reference for improving the structures of existing DI diesel and developing the new combustion systems.
It is more profitable for the natural gas hydrate exploitation by use of the depressurization in conjunction with hot brine stimulation. In the work, at the initial stage of the exploitation, the depressurization is used to induce the hydrate dissociation. When the temperature drops and causes the decrease of the hydrate dissociation rate, hot brine is injected to prompt the hydrate dissociation,...
Fraction collection following DNA electrophoresis has many applications in biology analysis. These assays typically need to identify specific DNA fragments in the separated sample for further processing and require extraction of one or a group of fragments. Unfortunately, the conventional methods involve cumbersome procedure and are not amenable to integration, automation and extraction of microscale...
