Drug delivery and translational research
Biodegradable polymeric microneedle arrays (BPMNAs) could be explored as potential devices for transdermal drug delivery, which can provide a painless and safe drug delivery method. BPMNAs could also provide high drug-loading capacity and prolonged drug delivery once integrated with a drug reservoir. However, the fabrication of MNAs with a drug res...

Atomic force microscopy (AFM)-based electrochemical etching of a highly oriented pyrolytic graphite (HOPG) surface is studied toward the single-atomic-layer lithography of intricate patterns. Electrochemical etching is performed in the water meniscus formed between the AFM tip apex and HOPG surface due to a capillary effect under controlled high re...

Abstracts. Ionic transport properties and diameter of asymmetric conical nano-pores in polyethylene terephthalate membranes were calculated. These nano-pores were synthesized by chemical etching method in irradiated polyethylene terephthalate (PET) films. After etching, the transport characteristics weredocumented under stepping voltage with 2M ion...

Electrochemical action and subsequent discharges are utilized in electrochemical discharge machining (ECDM) for the fabrication of components by subtracting the undesired material. However, as the process progresses, localized electrolyte vaporization (machining zone) and its leading effects limit the process performance. Controlled delivery of fre...

Femtosecond laser machining of biomimetic micro/nanostructures with high aspect ratio (larger than 10) on ultrahard materials, such as sapphire, is a challenging task, because the uncontrollable surface damage usually results in poor surface structures, especially for deep scribing. Here, we report an inside-out femtosecond laser deep scribing tech...

While cobalt (Co) stands out as the most effective non-precious metal for activating monopersulfate (MPS) to degrade organic pollutants, Co nanoparticles (NPs) are easily aggregated, losing their activities. As many efforts have attempted to immobilize Co NPs on supports/substrates to minimize the aggregation issue, recently hollow-structured carbo...

Slotted waveguides are often used when high-power and high-efficiency antennas must be designed and particularly for millimeter waves applications (automotive radar for example). But it is not easy to choose any distance between radiation slots because of the guided wavelength, to obtain a wide beam in E plane and so to cover a wide angular sector ...

This Ph.D. dissertation focuses on developing microfabrication processes to realize planar Fused Silica (FS) Micro-Electro-Mechanical System (MEMS) technology for the implementation of Micro-Rate-Integrating Gyroscopes (MRIG). Additionally, it includes a study on identifying error sources in Coriolis Vibratory Gyroscopes (CVG) with Whole-Angle (WA)...

Microfluidic devices consist of microchannels etched or embossed into substrates made of polymer, glass or silicon. Intricate connections of the microchannels to reactors with some smart mechanical structures such as traps or curvatures fulfil the desired functionalities such as mixing, separation, flow control or setting the environment for bioche...
