Selective immobilization onto the designated sites is particularly important as well as maintaining high spatial resolution down to the nanoscale to prevent unwanted nonspecifi c protein interactions. [ 6 , 7 ] Most previous attempts to form protein nanoarrays were done based on dip-pen nanolithography, which has been demonstrated as able to ensure nanoscale resolution with high selectivity. [ ...

Here we investigate the forming of superficial micro and nanostructures in poly(ethylene-2,6-naphthalate) (PEN), with a view to their use in biomedical device applications, and compare its performance with a polymer commonly used for the fabrication of these devices, poly(methyl methacrylate) (PMMA). The PEN is found to replicate both micro and nanostructures in its surface, albeit requiring mo...

The possible use of poly(ethylene naphthalate) as substrate for thin silicon solar cells has been studied in this paper. The transparency of this polymer makes it a candidate to be used in both substrate and superstrate configurations. ZnO:Al has been deposited at room temperature on top of PEN. The resulting structure PEN/ZnO:Al presented good optical and electrical properties. PEN has been su...

Abstract Polyethylene naphthalate (PEN) is an industrial plastic which interesting to the physics community as a wavelength-shifting scintillator. Recently, PEN structures with excellent radiopurity have been successfully produced using injection compression molding technology. This opens possibility for usage of optically active structural components wavelength shifting capabilities in low-bac...

Liquid argon is commonly used as a detector medium for neutrino physics and dark matter experiments in part due to its copious scintillation light production response excitation ionization by charged particle interactions. As appears the vacuum ultraviolet (VUV) regime difficult detect, wavelength-shifting materials are typically convert VUV visible wavelengths more easily detectable convention...

This protocol describes the fabrication and characterization of nanostructures using a novel nanolithographic technique called Patterning via Optical Saturable Transitions (POST). In this technique the chemical properties of organic photochromic molecules that undergo single-photon reactions are exploited, enabling rapid top-down nanopatterning over large areas at low light intensities, thereby...

The most important tool for controlling an industrial robotic arm is a teach pendant, which controls the robotic arm movement in work spaces and accomplishes teaching tasks. A good teaching tool should be easy to operate and can complete teaching tasks rapidly and effortlessly. In this study, a new teaching system is proposed for enabling users to operate robotic arms and accomplish teaching ta...

A webcam together with a standard pen can replace a mouse as pointing device for many common user interaction tasks. We provide an implementation of a dedicated image-processing component integrated in a ready-to-use software tool that acts as mouse alternative. The image-processing component is responsible for tracking the head of a pen based on shape and colour information retrieved in a quic...

Owing to a large diamagnetism, graphene flakes can respond and be aligned to magnetic field like a ferromagnetic material. Aligned graphene flakes exhibit emergent properties approaching single-layer graphene. Anisotropic optical properties also give rise to a magnetic writing board using graphene suspension and a bar magnet as a pen. This simple alignment technique opens up enormous applicatio...
