We have synthesized a prototype of a photochromic styrylquinolyl-dihydroindolizine (DHI), which forms a highly coloured and fluorescent betaine upon irradiation with lambda<400 nm. Embedding this photochromic DHI in a thin polymethyl methacrylate (PMMA) film permits the non-destructive readout via fluorescence at low temperature (77 K). Thus, either a non-destructive photoswitch or an informati...

To improve biocompatibility of hydrophobic polymethyl methacrylate intraocular lens (PMMA IOL), 2-hydroxyethyl methacrylate (HEMA) was immobilized by UV-induced graft copolymerization method. The hydrophilicity and chemical composition of the PMMA IOL surface after each step of surfaces modification were analyzed by contact angle (CA) and X-ray photoelectron spectroscopy (XPS). The morphology o...

This study focuses on fabrication of a micro plastic part using custom made vertical injection molding machine. Electrical discharge machining (EDM) and micro mechanical machining was used to fabricate micro shape cavity on aluminum mold. The mold was embedded with Polymethyl Methacrylate (PMMA) window to observe the behavior of plastic melt flow during injection. The custom made vertical injec...

We developed a novel single-step capillary electrophoresis (SSCE) scheme for field-amplified sample stacking (FASS) by using a hydrophilic material polymethyl methacrylate (PMMA) microchannel chip. The capillary effect was used to introduce liquids and control capillary stop valves in a partial barrier structure of the microchannel. Through the combined action of stop valves and air vents, both...

The possibility of regulating the retention and selectivity of monoalkyl- and polymethyl-substituted aromatic hydrocarbons in normal-phase high-performance liquid chromatography was investigated by modifying the non-polar (hexane) mobile phase with halide derivatives of hydrocarbons. Dichloromethane, chloroform, carbon tetrachloride and ethyl bromide were employed as modifiers. The decrease in ...

Supramolecular A8Bn miktoarm star copolymers were fabricated by host–guest complexation between a cavitand-based coordination capsule possessing eight polystyrene arms and biphenyl guest molecules with one, two, or four polymethyl acrylate arms, as reported Takeharu Haino co-workers in their Research Article (e202219001). The stability of the A8B1, A8B2, A8B4 polymers is influenced number polym...

Coupling between tunable broadband modes of an array of plasmonic metamolecules and a vibrational mode of carbonyl bond of poly(methyl methacrylate) is shown experimentally to produce a Fano resonance, which can be tuned in situ by varying the polarization of incident light. The interaction between the plasmon modes and the molecular resonance is investigated using both rigorous electromagnetic...
