In this paper, a dual-parameter liquid level and refractive index (R.I.) sensor is fabricated using three pieces of bare polymer optical fibers (POFs), which can independently simultaneously sense the R.I. The proposed design utilizes twisted coupling technique, in two are coupled with macro-bending. measurement depends on loss, where light transmitted to emission fiber (EF) acceptor (AF). measure depths up 125 mm sensitivity 8.03 nW/mm. Moreover, sensing macro-bending (TCMB) EF generates...
In sensor systems, most sensors are single-point detection, and it is challenging to develop a multi-point where multiple points can be sensed. This work reports low-cost relative humidity (RH) relying on intensity-variation based the side coupling technique using polymer optical fiber, three integrated into single illuminating fiber. The structure contains twisting of two fiber times coated with agarose-gel, while rise in causes change refractive index (RI) between twisted fibers....

Where, the could be varied at different locations as well depending on environmental conditions. present paper developed dual measuring sensor by using polymer optical fiber (POF) based illuminating fiber. sensor's basic structure is to twist two fibers and bend them certain radius. However, cascading of twisted micro (TMB-1 TMB-2). twisting couples light from one another side coupling method. An increase in level leads...
Silica fiber under high pressure increases the risk of breakage or permanent deformation, which may cause sensor failure due to mechanical strength limitations. High can also induce birefringence in optical fiber. In this study, we present a simple design and low-cost using polymer (POF) based on intensity-variation technique. A side-coupling mechanism structure is adopted, varies intensity with applied pressure. Two POFs are twisted together create sensing region where light launched first...

Abstract Recently, dyeing of cellulose nanofibers (CNF) has gained substantial interest due to its multifunctional properties, but discharge hazardous effluent containing salts are biggest challenges for sustainability textile processing sectors. Herein, we report deep eutectic solvents (DES) as a novel green medium dye CNF with anionic reactive dyes (without salts) the first time and parameters were optimized. Dyed in DES showed 37% higher color yield compared dyed conventional (with...
The paucity of in-situ records, particularly in the glaciated mountainous region, is an obstacle cryosphere ecology and environmental studies. Generally, available gauge station data fragmented covers valleys; thus, use gridded precipitation products (GPPs) crucial such complex terrains. However, these GPPs suffer from systematic biases uncertainties owing to parameterization deficiencies. Therefore, main goal this research systematically evaluate long-term performance differences newly...
