We describe the realization of a quantum key distribution (QKD) system clocked at 100 MHz. The system includes classical postprocessing implemented via software, and is operated over a 12 km standard telecommunication dark fiber in a real-world environment. A time-cost analysis of the sifted, error-corrected, and secret key rates relative to the raw key rate is presented, and the scalability of...

Fiber materials have advantages such as light weight and high strength, corrosion resistance, fatigue easy processing production, they are widely applied in the repair renovation of concrete structures. To promote construction convenience fiber materials, raw yarn is continuously braided to form fiber-belt-bars. Based on existing research, performance bonding between fiber-belt-bars a interface...

In this investigation dyeing of alginate fiber was carried out after cationic treatment of 11 EPTAC (2, 3-Epoxypropyl Trimethyl Ammonium Chloride). Optimum dyeing process and 12 parameter show good dyeing performance when alginate fiber dyed with rhubarb dye. In addition 13 to cationic treatment is taken into account for alginate fiber to improve fastness, color strength, 14 breaking strength. ...

Abstract Recent advances in additive manufacturing enable redesigning material morphology on nano-, micro-, and meso-scale, for achieving an enhanced functionality the macro-scale. From non-planar flexible electronic circuits, through biomechanically realistic surgical models, to shoe soles individualized user comfort, multiple scientific technological areas undergo material-property redesign e...

Recent years have seen an increase in the use of lignocellulosic materials in the development of bioproducts. Because sisal fiber is a low cost raw material and is readily available, this work aimed to evaluate its hemicellulose fraction for the simultaneous production of xylitol and ethanol. The sisal fiber presented a higher hemicellulose content than other frequently-employed biomasses, such...

The objective of this research was to evaluate an all-chemical process to prepare nano-scale to macro-scale cellulosic fibers from kenaf bast fibers, for polymer composite reinforcement. The procedure used in this all-chemical process included alkaline retting to obtain single cellulosic retted fiber, bleaching treatment to obtain delignified bleached fiber, and acidic hydrolysis to obtain both...

Although the world's forest resources have decreased, paper production has increased. Utilization of recycled fiber Recycle Fiber as a substitute for new Virgin in significant influence world industri. In 2011 industri reached 403 million tons and about (53%) was produced from paper. is cost competitive because lower than Fiber's fiber. Approximately (80%) this type comes three sources, namely ...
