Refractive Index Change of Cellulose Nanocrystal-Based Electroactive Polyurethane by an Electric Field

CMOS image sensor-based immunodetection by refractive-index change.

A complementary metal oxide semiconductor (CMOS) image sensor is an intriguing technology for the development of a novel biosensor. Indeed, the CMOS image sensor mechanism concerning the detection of the antigen-antibody (Ag-Ab) interaction at the nanoscale has been ambiguous so far. To understand the mechanism, more extensive research has been necessary to achieve point-of-care diagnostic devi...

Ultrasensitive Magnetic Field Sensing Based on Refractive-Index-Matched Coupling

An ultrasensitive magnetic field sensor is proposed and investigated experimentally. The no-core fiber is fusion-spliced between two pieces of single-mode fibers and then immersed in magnetic fluid with an appropriate value of refractive index. Under the refractive-index-matched coupling condition, the guided mode becomes leaky and a coupling wavelength dip in the transmission spectrum of the s...

development and implementation of an optimized control strategy for induction machine in an electric vehicle

Electric Field Induced Au Nanocrystal Formation in Aqueous Solutions

Preparation and Characterization of Waterborne Polyurethane Modified by Nanocrystalline Cellulose

Nanocrystalline cellulose (NCC) was used as a modifier for waterborne polyurethane (WPU) to investigate the water and ethanol resistance of WPU-NCC composites. The NCC surface was modified with γ-glycidoxypropyltrimethoxysilane (GPTMS) and γammnonimpropylmethyldimethoxysilane (APMDS) to improve its compatibility with waterborne polyurethane (WPU), as indicated by the contact angle (CA). The cha...
