We present a micromachined, stress-induced, thermal bimorph actuator for optical purpose. Piston motions of more than 3um are demonstrated by FEM simulation. Upon the release from the substrate, the actuators lift off the substrate due to a large built-in bending moment arising from the compressive residual stress in the poly-silicon layer and tensile residual stress in the metal layer. Large d...

Novel architectures with nanometric are very promising as building blocks for future nanotechnological applications. Metallic substrates with ordered morphology have been shown to be very effective for surface-enhanced Raman scattering (SERS). The sensitivity of detection is increased by several orders of magnitude by using this technique. In this paper we investigate SERS on thermal evaporated...

The present paper focuses on the investigation of self-cleaning properties based on studding of water repellency and blood repellency for TiN- and CrN single-layer and TiN/CrN nanoscale multi-layer coatings deposited via Cathodic Arc Evaporation (CAE) method on medical grade 420C stainless steel substrate. X-ray diffraction (XRD) method and Field Emission Scanning Electron Microscope (FESEM) wa...

This paper describes a novel approach of forming micropatterned co-cultures using a combination of oxygen plasma ashing and electrochemical removal of poly(ethylene glycol) (PEG) silane from indium tin oxide (ITO) substrates. After assembling a layer of PEG silane on ITO, photolithography and oxygen plasma cleaning were used to form cell-adhesive domains within the non-fouling PEG silane layer....

The design, materials, process, and fabrication of a hybrid substrate for the heterogeneous integration chips with 50μm-pitch (minimum) by fan-out chip-last panel-level packaging are presented. consists fine metal linewidth (L), spacing (S), thickness (H) RDL (redistribution-layer) substrate, solder joints underfill, build-up package substrate. dielectric material L/S/H RDL-substrate is an Ajin...

We introduce a novel optofuidic biochemical sensor in which detection is based on the contrast between the refractive index of a target biomaterial and ambient carrier fluid. The sensor consists of parallel vertical micochannels embedded in a planar substrate. The central microchannel is illuminated by a focused beam of light and the periodic spacing of the channels combined with the contrast i...

Owing to recent advances in chemical vapour deposition, graphene sheets can now be made in quantities that are large enough for essentially all research and development purposes1–3. For practical applications, however, new methods are required to transfer the graphene from the growth substrate to a target substrate without damaging either the graphene sheet or the target surface. Various transf...

The structure of softly supported polymer-cushioned lipid bilayers, prepared in two different ways at the quartz-solution interface, were determined using neutron reflectometry. The polymer cushion consisted of a thin layer of branched, cationic polyethyleneimine (PEI), and the bilayers were formed by adsorption of small unilamellar dimyristoylphosphatidylcholine (DMPC) vesicles. When vesicles ...

Gadolinium oxysulfide phosphor doped with trivalent terbium have been synthesized using urea homogenous precipitation and followed by sulfurization at 800 °C under argon atmosphere. Structural and morphological of synthesized phosphor powder were characterized by x-ray diffraction (XRD), scanning electron microscopy (SEM) and Fourier transform infrared spectrometry (FT-IR). Hexagonal structure ...
