An Automatic Microscope Image System on Textile Fibers
关键字：Automatic microscope, quantitative measure, shape index, resin slice
With the development of chemical fiber forming technology, it is necessary that quantificational methods replace qualitative methods for cross shape measure. So an automatic image analysis system on textile fibers is developed to repla...

Alternating and regioregular copolymers with high refractive index from COS and biomass-derived epoxides
This study describes the catalytic formation of alternating and regioregular copolymers from carbonyl sulfide (COS) and epoxides along with eugenol-based glycidyl ether (EGE) and guaiacol-based glycidyl ether (GGE), derived from eugenol and guaiacol, respectively. The (salen)CrCl [salen ? N,N0-bis(salicylidene) cyclohexanediimine] complex, accompanied with various organic bases, was highly activ...

Well-defined high refractive index poly(monothiocarbonate) with tunable Abbe''s numbers and glass-transition temperatures via terpolymerization
The synthesis of thermoplastics with high refractive index (n) and high Abbe’s number (Vd) is rarely reported. This work describes well-controlled synthesis of a soluble poly(monothiocarbonate) with high n and Vd values by using carbonyl sulfide (COS) as sulfur resource. The alternating COS/cyclohexene oxide (CHO)/propylene oxide (PO) terpolymerization was well performed by using...

High-refractive-index transparent coatings enhance the optical fiber cladding modes refractometric sensitivity
The high order cladding modes of standard single mode optical fiber appear in quasi-degenerate pairs corresponding to mostly radially or mostly azimuthally polarized light. In this work, we demonstrate that, in the presence of a high-refractive-index coating surrounding the fiber outer surface, the wavelength spacing between the orthogonally polarized cladding modes families can be drastically enh...
