Effect of Alcohol as Additives on the Morphology and Separation Performance of Polyethersulfone (PES) Hollow Fiber Ultrafiltration Membranes [PDF]
Engineering and Technology Journal, 2008 Hollow fiber ultrafiltration (UF) membranes were prepared using Polyethersulfone(PES), alcohol (n-Propanol) as additive and N, N-dimethylacetamide (DMAc) as asolvent. Asymmetric hollow fiber UF membranes were spun by wet phaseinversion method from 17 wt%

Hollow Fiber Coupler Sensor [PDF]
Sensors, 2019 We present a bi-conical optical directional coupler composed of solid and hollow core fibers. Through an evanescent wave coupling mechanism, the detection of liquid refractive index and its temperature are demonstrated. The experimental results illustrated that the sensor offers a sensitivity of 4.03 ± 0.50 volts per refractive index units (V ...

Fiber design for high-power low-cost Yb:Al-doped fiber laser operating at 980nm [PDF]
, 2007 We investigated an Yb:Al-doped depressed-clad hollow optical fiber (DCHOF) for cladding-pumped 980nm laser operation. With a careful design, the nonzero fundamental-mode cutoff characteristics of a DCHOF allows the competing 1030-1060nm emission to be ...
