Paper, matted or felted sheet, usually of cellulose fibers, formed on a wire screen from water suspension. Although wood has become the major source of fiber for papermaking, rag fibers are used for paper of maximum strength, durability, and permanence.
Making paper without trees. (alternate sources for paper manufacture)(includes related article)Ayres, Ed
Although the paper machine symbolizes the mechanization of the paper industry, every step of production, from the felling of trees to the shipment of the finished product, has also seen a dramatic increase in mechanization, thus reducing hand labour. As papermaking operations require the repeated ...
People tend to use trees for papermaking.But maybe electronics (电子) engineers are missing out on something here. "It turns out that two major building blocks of wood have a lot of electrical qualities," says Magnus Berggren,a professor at Linköping University.His team has been working to...
根据文章第二段“His team has been working to make parts for electronics from the forest. Right now, they’re focusing on two materials of trees. The first material is cellulose, which can make energy. Lignin, the second material, can store that energy, just as a battery does. The team ...
When the video image is taken with a static camera, there is no matching problem, but when the camera is moving, it is difficult to match the previous frame and the new one. Therefore, to subtract the frames, camera movement must be taken into account. In this paper, we present a ...
Sometimes this is scrap fiber from sawmills, but it mostly comes from trees cut specifically to make paper. A growing trend is to use a percentage of recycled paper or cloth. The common factor of all these materials is cellulose fibers, long strands of strong fiber found in all plants, ...

province, for three years, where he has seen many changes and feels the potential of the city. As a scientist in the field of paper pulp making from agriculture, he is trying to find other raw material from agricultural waste for paper making, "so we don't need to cut the trees," ...
