3D printed titanium scaffold has promising applications in orthopedics. However, the bioinert presents challenges for promoting vascularization and tissue growth within porous stable osteointegration. In this study, a modular is created using printing gradient-surface strategy to immobilize QK peptide on surface with bi-directional gradient distribution. This design featured high density interior low both ends, aiming induce cell migration from ends subsequently enhance osteointegration...
A new low-cost, high throughput method was developed for fabricating large area quantized magnetic disks (QMDs) using nanoimprint lithography (NIL), electroplating, and chemical mechanical polishing. Perpendicular QMDs with a density of 18 Gbit/in.2 good uniformity over an 4 cm×4 cm (total 45 Gbit) have been achieved, as well longitudinal 30 The NIL molds the perpendicular were fabricated double grating mold. properties both types studied by force microscopy.
We have demonstrated a method to directly pattern organic light-emitting structures with submicron resolution without any degradation in optical properties. Both small molecules and polymer-based were patterned by nanoimprint at 150 °C vacuum. The comparison of luminescence efficiency before after patterning shows that did not cause the property materials. Nanoimprint offers low-cost, high-throughput, high-resolution technique opens way for realizing novel photonic devices based on
Five multilayer resist methods (three positive tones and two negative tones) have been devised for nanoimprint lithography on nonflat surfaces. Three of the demonstrated experimentally a SiO2 surface with 100 nm deep sharp steps. The advantages disadvantages each method are discussed. Our results should be applicable to 10 feature size
The dynamic behavior of lithographically induced self-assembly (LISA), a newly discovered pattern formation phenomenon, was recorded and analyzed with real time video. Two surprising intriguing phenomena were observed. First, LISA pillar array formed in an orderly manner starting under the corners mask pattern, then edges, later propagating to center pattern. Second, interval between two subsequent pillars has shell structure. observation presents evidence critical uncovering physical origin...
Quantized magnetic disks consisting of an array single domain Ni pillars with a density 18 Gbits/in.2 were fabricated using nanoimprint lithography (NIL) and electroplating. The total disk area, limited by the NIL mold, is 4 cm×4 cm, leading to 45 Gbits. Magnetic force microscope (MFM) images show that all 70 nm in diameter 400 height are domain. magnetostatic interaction between adjacent fairly strong. have average switching field 360 Oe can be switched MFM tip large moment.
We report a promising approach to align molecules in polymer film patterned by nanoimprint lithography. found that and chromophores are spontaneously aligned the plane of during nanopatterning process. Since polymer–chromophore (called guest–host) system plays an important role field nonlinear optics organic optoelectronics, this letter we present technique combine high-resolution patterning capability lithography with ability control molecule chromophore orientation. It opens up way realize...
Controlling surface wettability has important application prospects in many aspects. Both the Cassie–Baxter equation and Wenzel explain effects of chemical composition roughened texture on wettability. Recently, third factor—reentrant curvature—has been proposed; nonetheless, its impact based theoretical calculation never investigated. Based theory proposed by Marmur, herein, overlap fraction ϕr was introduced to effect, three novel necessary conditions for existence Cassie state were drawn....
Superhydrophobic surfaces are currently under intense investigation due to their superb properties and enhanced performance. Along these lines, in this work we present a novel designing scheme consisted of five different microstructures (cone structure, pyramid cone ridge adhesive interconnect topology structure). The static properties, as well the wettability all configurations, evaluated by applying both comprehensive numerical model mathematical approach for contact issue. From our...
