SAFETY
One of the most important features of synthetic winch lines is the safety benefits they provide. Synthetic lines do not store energy while under load and are very lightweight. This means that if something should go wrong and the rope breaks, it will harmlessly fall to the ground. Steel wire rope on the other hand, stores a tremendous amount of energy under load, and in the case of breakage, will violently snap back and whiplash. This can cause serious injury to people involved in the winching procedure.
Synthetic winch lines don`t have any wire splinters or burrs like steel wire ropes commonly do, so there is no chance of getting a surprise hand injury while handling a synthetic line.

STRENGTH
Synthetic winch lines have breaking strengths 30-90% higher than steel wire rope. This is a tremendous increase and allows for smaller diameter winch lines to be used when switching to synthetic, therefore increasing the amount of line that can be installed on the winch.
WEIGHT
Synthetic winch lines are up to 80% lighter than steel wire rope. Aside from the safety benefits mentioned above, this offers some obvious advantages. On a typical recreational off road vehicle, switching to a Synthetic Winch Line and an Aluminum Hawse Fairlead will shave up to 30 pounds of weight from the front of the vehicle. Rigging vehicle extractions is also much easier, especially in loose, hilly terrain. Synthetic winch lines are so light, they even float.
Arsenic (III) electrochemical detection mechanism
Researcher Liu Jinhua, chief scientist of Bionic Functional Materials and Sensors Research Center of Bionic Materials and Sensors Research Center, Institute of Intelligent Mechanics, Chinese Academy of Sciences, and researcher led by Huang Xingji, a researcher of the Chinese Academy of Sciences for “bringing in outstanding overseas talentâ€, recently, exploring arsenic (III) ) Achieve new breakthroughs in the mechanism of electrochemical detection.
For a long time, it is a difficult and important problem to realize stable and efficient electrochemical detection of arsenic(III) in complex environments. The interference caused by other ions such as mercury (II), copper (II) and natural organic matter has always been a matter of particular concern to researchers. The previous reports on the impact of interference on the mechanism of little research, lack of theoretical and experimental basis.
Hefei Research Institute of Intelligent Institute researchers from the perspective of practical application, relying on the groundwater in the village of Xingwangzhuang, Tuoketuo County, Inner Mongolia as the background, with the help of spectroscopy to study the humic acid and iron (III) on the electrochemical signal of arsenic (III) influences. The results show that humic acid can complex with arsenic(III) in water, thus affecting the detection signal; while the presence of iron(III) can combine stronger forces with humic acid, eliminating humic acid and gold electrodes or As The combination of (III) enables a stable and highly efficient electrochemical detection of arsenic (III). Research papers were published in the environmental journal "Hazardous Materials" (J. Hazard. Mater. 2014, 267, 153). The reviewer believes that “this work provides a relatively deep understanding of the effects of interferents on electrochemical signals relative to the detection of arsenic(III)â€; “this work is novel, and it is a novelty that eliminates these effects on arsenic analysis. The new possibility of acid brings an idea."
In recent years, researchers of this research group have been devoted to exploring the correlation of nano-materials in electroanalytic behavior and adsorption performance. In this regard, they investigated the adsorption properties of heavy metals such as arsenic (III), arsenic (V), and cobalt (II) in water using amino functionalized graphene oxide and porous double metal oxide (yttria-zirconia) nanospheres. Related studies have demonstrated in depth the important role of surface functional groups in the removal of heavy metals. The research results are also published in full text in "Hazardous Materials" (J. Hazard. Mater. 2013, 260, 498; J. Hazard. Mater. 2014, 270, 1).
The above research work has received the support of the National Major Scientific Research Plan Project, the Chinese Academy of Sciences' 100 Talented Personnel Program for the Introduction of Overseas Outstanding Talents, and the Hefei Physical Science and Technology Center Project.
